1. Summary
While the population of the Eurasian Griffon Vulture in the western European range
(Iberian Peninsula, France) has greatly increased during the last three decades,
populations in the eastern European and Mediterranean range must be considered
as endangered and were extinct from many parts of their former distribution.
Due to this highly worrying development, the Eastern European/Mediterranean
Griffon Vulture Working Group working group (EGVWG) was established in 2000.
Besides this, an evaluation of the current status and distribution, activities focussed
on the development of an Action Plan which is now available.
We are aware about the fact that all old vulture species are endangered in this
geographic range, and in this context we see the Eurasian Griffon Vultures as the
species which received the least attention up to now. We wanted to stress the fact
that even this species which is comparably widely distributed and more abundant
when compared with other vulture species must be considered as endangered. It is
obvious that all activities and actions which are suggested in this Action Plan are
highly beneficial for all other old world vulture species. However, we concentrate with
this Action Plan on the Eurasian Griffon Vulture (Gyps fulvus).
The total population size equals around 20.000 breeding pairs with only 10% of the
population outside the Iberian peninsula (Del Moral & Marti, 2001). While Spain,
Portugal and France (the latter with a high percentage of successfully reintroduced
colonies) are mainly confronted with a management problem, a severe conservation
problem is evident for the rest of the range and requires urgent actions.
Main threats for the Eurasian Griffon Vulture population are poisoning, lack of food,
changes of land use practices with decreasing numbers of domestic and wild
ungulates, electrocution, disturbance, persecution (shooting and egg robbing).
This Action Plan summarizes the status and distribution of the Griffon vulture and
describes the required actions.

2. Introduction and background information 2.1 Legal Status
The Eurasian Griffon Vulture is protected throughout the range of countries which are
covered in this Action Plan (AP). However, according to the country considered,
national laws vary greatly, and the species may be subject of laws for nature
protection and/or hunting. In any case it is strictly protected throughout the whole
hunting season. Besides protection on a national level, there are numerous
International conventions which apply to the Eurasian Griffon Vulture and which are
signed by most of the countries listed in this Action Plan. Under international
Conventions and Directives, the Eurasian Griffon is classified as follows:
EU Bird Directive: Annex I
The species mentioned in annex 1 shall be the subject of special conservation
measures concerning their habitat in order to ensure their survival and
reproduction in their area of distribution.
Bern Convention: Annex II
The following actions will in particular be prohibited for these species:
(a) all forms of deliberate capture and keeping and deliberate killing;
(b) the deliberate damage to or destruction of breeding or resting sites;
(c) the deliberate disturbance of wild fauna, particularly during the period of
breeding, rearing and hibernation, insofar as disturbance would be significant
in relation to the objectives of this Convention;
(d) the deliberate destruction or taking of eggs from the wild or keeping these
eggs even if empty;
(e) the possession of and internal trade of these animals, alive or dead, including
stuffed animals and any readily recognisable part or derivative thereof, where
this would contribute to the effectiveness of the provisions of this article.
CITES Annex II
(a) all species which, although not necessarily now threatened with extinction may
become so unless trade in specimens of such species is subject to strict
regulation in order to avoid utilization incompatible with their survival; and
11
(b) other species which must be subject to regulation in order that trade in
specimens of certain species referred to in sub-paragraph (a) of this
paragraph may be brought under effective control.
BirdLife International
Secure and Non SPEC: Although the species continued to decline in Turkey and the
Caucasus 1990-2000, most other populations increased or
were stable, the species is now evaluated as Secure
(BirdLife International 2004).
The Geographical Scope of this Action Plan is primarily intended to cover the
western Palearctic species range, although the lack of available information and
practical feasibility in a number of countries may make its implementation in those
areas rather difficult. The recent distribution of breeding populations in the world
comprises the following countries: Armenia, Algeria, Austria, Bulgaria, Croatia,
Cyprus, France, Georgia, Greece, Israel, Italy, Jordan, Republic of Macedonia,
Morocco, Portugal, Serbia, Spain, Turkey and Albania.
Other countries where the species probably bred in the past: Germany (Glutz et al.
1971), Poland (Tomialoj´c 1976), Rumania (Bijleveld 1974, Puscariu & Filipascu
1977). Accidental observations have been recorded for Britain, Ireland, Belgium and
the Netherlands, Finland, Hungary and Tunisia.
2.2. Taxonomic Status
Gyps fulvus (Hablizl, 1783). Monotypic. Two subspecies are being distinguished:
1) Gyps f. fulvus (Hablizl, 1783) occurring in NW Africa, Iberian Peninsula and to
the E through the Balkans, Turkey, Middle East, Arabia and Iran to Pamir and
Altai.
2) Gyps fulvus fulvescens (Hume 1869) in Afghanistan, Pakistan and N India and
E to Assam.
12
2.3. Distribution and Population Status
The Eurasian Griffon Vulture is distributed as a breeding bird over the western
Palearctic from India, Pamirs and Altai in the east, to Portugal and Spain in the west.
Areas in southern Europe surrounding the Mediterranean are the core-range with a
strong focus on the Iberian Peninsula. The total population comprises around 20.000
– 30.000 breeding pairs and a total population (including non-breeders) of unknown
magnitude.
Breeding populations are sedentary whereas younger birds are migrants or vagrants.
They may wander widely. Migration and wintering areas include countries in Africa
south to the 20º N in Senegambia, Mali, Chad and probably Niger. South to the
Middle East wintering grounds are in Somalia and Ethiopia. Other significant areas
concur with the breeding range as is the case on the Iberian Peninsula gathering up
to 1,000 individuals. In Asia, small numbers have been recorded wintering.
Once widespread across the continent, the species has undergone dramatic declines
leading to extinction in the Alps and the Carpathians. These declines were mainly
due to persecution by man and poisoning. The remnant populations are isolated and
in urgent need of conservation action assisted by international cooperation and
provision of expertise.
In 1986 the distribution of the Griffon Vulture was clearly distinct into two parts
(Gensbøl & Thiede 1986; Figure 1). In the western part of its range was found mainly
on the Iberian Peninsula, northern Morocco, whereas in the east the Griffon Vulture
occurred in Greece, Turkey, the Ural Mountains and certain regions of Israel and
Jordan. In between there are only a few small populations mainly on the Balkans.
To evaluate status of the population, trends and threats, a standard questionnaire
provided by BirdLife International was used. Beside parameters obviously influence
griffon habitat quality also parameters which are primarily linked to climate change
were asked for.

In 2002 the distribution range is much more patchily but quite similar to the results
from 1986 according to the data collected for this Action Plan. On the Iberian
Peninsula the Griffon vulture is established quite well and doubled its population size
every 8 years (Table 1). In a lot of the countries where the species occurred 16 years
ago, the population decreased and the distribution has turned to be very scattered.
Especially in Greece and Turkey where the Griffon Vulture formerly showed a
compact distribution, only few populations in small patches can be found. This is also
true for Croatia where griffons remained only on some Adriatic islands. In contrast, in
between the eastern and the western population populations have been established
in France and Italy as a consequence of reintroduction programmes since the 1980s.
This new colonies are important as stepping stones.
If we exclude the Iberian peninsula, the populations seems stable in Europe during
the last 16 years with about 2000 pairs. Including Spain the population equals about
a magnitude of some 20.000 pairs. This means that only 10% of the population exist
on about 90 % of the species range.

According to the data of the two censuses results differ but cross numbers are similar
for both reports (Table 2). It is noteworthy the role of the Iberian Peninsula on the
conservation of the Eurasian griffon. With these data Spain holds the 86.19-91.05%
of all these population estimates (87.48- 92.45% of breeding pairs included in the
Iberian Peninsula). The EGVWG Status report also includes other countries such as
Morocco (where the species seems to be extinct as breeder) Jordan and Israel
together with other republics from the former Soviet Union (Kazakhastan,
Uzbekistan).
2.4. Life History
General Biology
The Eurasian Griffon Vulture Gyps fulvus is a specialized scavenger, which inhabits
rugged and mountainous areas in southern Europe surrounding the Mediterranean.
Life History
The Griffon Vulture is generally a colonial breeder, comprising from one to more than
100 pairs (Del Moral & Martí 2001) Typically the species breeds on cliffs but
exceptionally also on trees (Spain and Portugal, Traverso 2001). Rarely the species
breeds alone. Breeding starts early in the year. Timing varies regionally but generally
occurs not later than the end of January due their long breeding cycle. In some areas
breeding may start as early as December with earliest copulation behaviour in
November in Spain (Camiña pers. obs.) but may also occur as late as April at the
northern slope of the Alps (Bögel & Mäck 1989). Breeding has not been recorded by
birds younger than 4 years old. Generally, breeding starts when reaching adult age
with 5-6 years. However, large proportions of birds with “subadult” plumage criteria
have been recorded breeding at earlier stages probably as a consequence of high
food availability (Blanco & Martinez 1996). They only lay one egg, with an incubation
period of 55 days on average. The fledging period is 110-132 days. Replacement
clutches may exists up to May. Very little is know regarding the post-fledging
dependence period. Most of the juvenile population disperse or partially migrate
(Bernis 1983, Griesinger 1996, Griesinger 1998) and only a few number may stay
with their parents year round probably related with good food supply. Juvenile ringed
vultures have been recorded as far as Gambia, Senegal, Mali, Chad and Niger.
17
Breeding success varies among different areas, in accordance with food supply
(Fernández et al. 1998), intraspecific concurrence (density of breeding pairs), site
characteristics and climate, It ranges from 0,3 – 0,8 young/pair (Terrasse 1961,
Leconte 1977, Arroyo et al. 1990) The Eurasian Griffon Vulture is a long-lived, slow-
reproducing raptor, compensating for a low annual offspring production by high adult
survival. This makes the species highly sensitive to a decrease in adult survival,
whereas a decrease in juvenile survival or a temporary decrease in productivity will
have a much lower effect on population dynamics. However, a reduction in
productivity over a prolonged period will threaten the population as well.
Feeding
The Griffon Vulture almost exclusively feeds on carrion. Only very few records have
been made where Griffons approched injured and weak individuals of sheep or cattle
(Camiña et al. 1995, Camiña 2004). The diet is mainly comprised of livestock species
(sheep, goat, cattle and horses) (Fernández 1975, Camiña 1996). Wild ungulate
species (Rupicapra rupicapra, Cervus elaphus, Capreolus capreolus) is consumed in
certain areas (Pyrenees, Alps) where these species are abundant and carcasses are
accessible (open areas).
Habitat requirements
Breeding is mainly restricted to cliffs reaching from just above sea-level to heights of
up to 2,500m. On average cliffs are usually below 1,500m a.s.l. In Spain and
Portugal, nests have also been located on trees where Griffons occupy Cinereous
Vulture (Aegypius monachus) nests (Traverso 2001).
Movements
Adult individuals are largely sedentary. Partial migration occurs for juvenile and
immature birds which leave their breeding areas at the end of breeding season,
probably in order to locate better feeding resources and thereby avoiding competition
with adults (Camiña 1996). This may motivate young birds to fly as far as south of the
Sahara (Bernis 1983, Mundy et al. 1992, Griesinger 1996, Griesinger 1998).
Concentrations of migrating birds do occur during the migration periods at specific
points like Gibraltar and Suez (Bijlsma 1987). However, as the species can stay year
18
round also under very harsh climatic conditions as long as the food availability is
guaranteed (Bögel pers. obs., Bahat et al. 2001).
2.5 Threats
• Poisoning – critical
• Decline of intensive livestock farming – high
• Food shortage – generally high (for Spain: medium)
• Electrocution and collision with powerlines and overhead cables – high
• Loss and degredation of habitat – locally high
• Disturbance – locally high
• Illegal Shooting – potentially high
(Definition of criteria see table 2)
Poisoning
Despite the well established legal protection, direct persecution takes place and it is
documented for Griffon and other vulture species. However, direct persecution is a
problem of subdominant order.
The main problem for Griffon Vultures is caused by poisoning and habitat loss.
Poisoning is generally addressed towards the recently increased populations of
mammalian predators such as wolf / dogs (Canis lupus / ssp.), bear (Ursus arctos),
lynx (Lynx lynx), foxes (Vulpes vulpes), jackals (Canis aureus) and mustelids but can
also be caused by agrochemicals (for example rodenticides) which are frequently
used in many countries. They can be purchased in many countries without any

restriction or regulation. In most cases, the target animals are not vultures, so
secondary poisoning is the dominant problem.
Frequent chemicals used are carbamates, cyanids and organophosphates; popular
products are lannate, strychnine, bromadiolon, brodifacoum, difenacoum and
flocoumafen. Lead poisoning caused by feeding on remains from shot animals was
also considered to be a problem of great concern. In this context it is important to
stress the fact that due to the species biology (see above) and etho-ecological facts
(highly efficient food searching strategies, feeding in groups, low capacity for natural
re-colonisation) Griffon vultures are extremely sensitive towards poisoning.
As with the poisoning problem vultures are secondary targets in the context of
trapping and shooting. The birds are killed by traps or baits which are not primarily to
them but mainly to large predators like wolf or bear and sometimes wild boar.
Habitat loss (breeding site and food availability)
Habitat loss is a problem which refers to both factors affecting the distribution of
raptors (Newton 1979) - food availability and breeding sites. The main food source of
Griffon Vultures in Europe and the Mediterranean comes from domestic livestock.
Thus, traditional rearing livestock practices must be maintained in order to ensure
food provision. In many parts of Europe, traditional forms of extensive farming such
as transhumance have been changing greatly along with socio-economic
developments, generally decreasing the food supply massively. However, in some
areas, a revitalisation of such practices currently takes place. Feeding of vultures
within countries of the European Union range is closely linked with subsidies from the
Common Agricultural Policy. It is important in this context that adequate food supply
is not only a question of sufficient numbers of grazing livestock but can also be a
problem of easy access to carcasses in some regions. In many parts of the area
covered by this AP, vulture restaurants or feeding stations were established in order
to fulfil two important management issues: i) provide vultures with enough food, and
ii) to guarantee a safe food supply with the aim to reduce the risk of exposure to
poisoned baits while foraging. However, due to EU-regulation which have been
established recently along with the BSE crisis (Camiña 2001, Camiña 2004), a
severe problem of legal operation of such feeding sites was created which urgently
requires a quick solution.
21
In few occasions (for example for Turkey) natural succession and forest management
(forestation of formerly open areas) has been considered to have a negative effect on
foraging capabilities of vultures.
In this context it is important to note, that wild ungulates can play an important role
for the food supply of Griffon Vultures. However, this important food source has been
diminished to a huge extend, partly by over-harvesting (eastern and southern
Europe) and partly by doubtful management measures in order to reduce forest
damage (central Europe).

Electrocution and collision with powerlines and overhead cables
Electrocution is another problem whose extent on vulture populations can currently
not be accurately assessed. Some work has been developed in Spain (Alonso &
Alonso 1999) with varying experiences from other countries (comp. Hartley et al.
1996, Houston 1996). These studies showed, that losses caused by electrocution are
high and solutions, like adequate pole design, have been developed to solve the
problem (Ferrer & Janss Coord. 1999). Other types of infrastructure may have
adverse effects on Griffon populations. They can result in a highly fragmented
landscape or in the access of humans close to breeding or important feeding sites
and thus create a problem of disturbance (see below). In Europe there has been an
important development of windfarms in some countries. At least in Spain, vultures
are one of the most affected raptor species (Camiña in press). In recent years large
numbers of griffons have been collated after collisions with turbine blades. A correct
windfarm design, the avoidance of any construction close to breeding or foraging
sites and rigorous studies on the space and habitat use of the windfarm area are
urgently needed. Furthermore, losses resulting from collisions with overhead cables
such as cable cars has been documented (Bögel, pers. communication).
Tourism and other disturbances
Concerning breeding sites, this is mainly a problem of disturbances by trend sporting
activities (climbing, paragliding, etc.) and/or recreation/curiosity. Especially on the
Adriatic islands but also elsewhere this is (or it has been) a problem resulting in
drowned juveniles and (at least in one case) in an extinction of a breeding colony. In
few cases, mining activities have also been supported as a potential threat (for
example in Bulgaria).
It is important to note that threats and their relative importance vary greatly with the
geographic range which is considered. As also reflected by population dynamics
during recent years, the situation is good in the western European-Mediterranean
region (Iberian peninsula and France) mainly consisting of a management problem
while in the eastern range we face severe problems with a massive risk of extinction.
Detailed information can be found in the country-specific listing of this AP. Figure 2
summarises threats and reflects the relative importance of various threats.

Mediterranean
3.1 The Situation of the Griffon vulture in Albania
The information available for Albania is rare (B. Grubac pers. communication). The
population decreased substantially during the last decades but Griffon Vulture flocks
are regularly observed in the bordering areas to Greece, Macedonia and
Serbia/Kosovo (up to 40 birds). If breeding pairs still exist is unclear. However, one
colony with few breeding pairs is hypothized by B. Grubac.
Illegal shooting, changes in land use practices, poor food supply, and habitat loss are
the main causes for this development. Poisoning seems to be a subdominant
problem at present.

Distribution:
Armenia has an area of 29800 km². The Eurasian Griffon Vulture has been
extensively studied by B.O. Geilikman (1966, 1975) between 1953 – 1990. From
1993 onward studies continued within the framework of the project “Birds of Armenia”
(1993-1995) and as part of the thesis “Some peculiarities of vertical distribution and
ecology of the birds in Meghri region of Armenia” (1996-1998). In 2002, a pilot survey
was conducted. The collected data show that Griffon Vultures breed in the Northern,
Central, Southern and South-Eastern parts of Armenia. The species inhabits habitats
from the semi- desert up to mountain forest zone (from 700 to 2000m a.s.l.) and
feeds mostly on open areas like the semi-desert, the mountain steppe and the sub-
alpine zone. The main food item of the Eurasian Griffon Vulture in Armenia are
25
Armenia
Turkey
Azerbaijan
26
livestock carcasses; however, the native food items are wild ungulates. The species
breeds on huge rocks (width: 70-200m) with many caves and niches. In total, 6
colonies of Griffon Vultures are known: 5 inside Armenia and 1 in the border region
with Nakhichevan (Western Azerbaijan enclave). The number of birds in the
remaining known colonies are as follows:
• Khosrov Preserve (central Armenia): 2 colonies with 14-20 birds
• Alaverdi region (northern Armenia): approx. 15 birds
• Meghri region (south-eastern Armenia): 8-10 birds
The total number of birds in two other colonies accounts for 13-15 birds.
During last 10 years the Griffon Vulture population has declined by at least 50%. It is
very likely that this decline is linked to local economic changes after breakdown of
the former USSR which resulted in illegal killing of wild ungulates and a decline of
livestock numbers, both remarkably decreasing the food supply.

Distribution:
The breeding population is restricted to Salzburg county with a strong focus on the
northern slope of the Austrian Alps. This breeding population originates from a
release project at Salzburg Zoo during the 1960’s. First breeding occurred during the
beginning of the 1980’s. The population size of the colony fluctuates between 10 and
20 individuals. Although some constant food supply is provided at the zoo (430 m
a.s.l.), most activities (breeding, foraging, etc.) occurs in the high Alps (> 1500 m
a.s.l.; foraging area approx. 150 km²).
Additionally, a non-breeding population exists in the Central Austrian Alps (“Hohe
Tauern” region). This consists of up to 100 individuals with a southern origin (mainly
birds from the “Kvarner Islands” / Croatia but also from “Friaul” / Italy). Those non-
breeders are migrants and use this area from May to October (foraging area approx.
500 km²). Regular interactions between the breeding population at Salzburg Zoo and
the non-breeding population occur.

Distribution:
In Bulgaria this species is represented by one colony of breeding birds, which is in
the valley of the river Arda in the Eastern Rhodopes (Southern Bulgaria, near the
Greek border). There are two distinct breeding groups within the colony: one is near
the town of Madzharovo – 19 breeding pairs; the other one breeds in the area of the
Studen Kladenets dam ca. 30 km away – 11 breeding pairs (2001). The feeding area
of the colony is approximately 250 km².
Small groups of Griffon Vultures are sporadically observed in the mountains of the
Eastern Fore-Balkan, Eastern and Western Balkans, Gornotrakiiska Lowland,
Western Rhodopes and Western outlying districts. Individual birds were observed in
the Western Balkan, Strandja Mountains and the Kresna gorge.
The Eastern Rhodopes landscape is characterized by exceptionally great
compositional and structural diversity. The compositional diversity is defined by the
big number of different habitats (45 types), and the structural by mosaic patterns due
to the diverse relief and different interferences. The Eastern Rhodopes are the only
relatively compact mountain area in Bulgaria with such considerable differences in
altitude – from 45 m to 1483 m a.s.l. Besides, this part of the Rhodopes is located
close to the Aegean Sea, substantial territories being directly exposed to the impact
of this part of the Mediterranean.
The principal livelihood of the people in Eastern Rhodopes is extensive
stockbreeding and tobacco growing. Additionally, there was a well-developed mining
in the near past, but presently the mines are no longer in use.

3.5 The Situation of the Griffon vulture in Croatia Goran Susic
Ornithological Station Cres, Institute of Ornithology / Croatian Academy of Sciences
and Arts
Legal protection of the species:
The species is protected according to the Nature Protection Act (new version of
1994). Almost all Croatian breeding birds, excepting hunting species, cormorant on
fishponds and starling on agricultural land (i.e. 283 bird species) are protected under
the Nature Protection Act.

Distribution:
At the end of 19th century Griffons lived all over the country, along the Dalmatian
coast as well as on 11 Adriatic islands, even in lowland Slavonia near Sava and
Danube River. At the beginning of the 20th century, the Croatian population of
Eurasian Griffons declined rapidly in numbers and in range. Today the Eurasian
Griffons breed only on the Kvarner islands: Cres, Krk, Plavnik, Prvic, and,
occasionally, on the island of Pag. Their survival is linked to the traditional farming
practices of leaving sheep carcasses in the field to be consumed by Griffons.
Eurasian Griffon is a kind of peculiarity for the coastal area of Croatia as it breeds
exclusively on the cliffs above the sea, some nests being located only 8m above sea
level. The recent breeding colonies are situated on the cliffs of the Northern Adriatic
islands in the Kvarner area (Cres, Krk, Prvic and Plavnik) with a total breeding
population of about 90 pairs (Suši 2002). Due to the active protection, the population
on the Cres island has grown from 25 to 70 pairs during
35
Serbia
Slovenia
Croatia
Bosnia Herzegovina
Montenegro
Hungary
36
the last 15 years, while it had decreased drastically or even disappeared on other
breeding sites (for example at Paklenica National Park). Illegal poisoning and
disappearance of traditional extensive sheep breeding in the coastal zone of Croatia
are the biggest threats to the population. Number of pairs constantly decreases on
the island of Prvic (from 25 pairs to 15 pairs during the last 5 years) and on the island
of Krk (from 12 to only 3 pairs, during the last three years).
At the end of September most of the juvenile birds leave the colony, so there are
almost no juvenile, immature and sub-adult birds over-wintering on the above
mentioned islands. When they reach sexual maturity (5 years old) they come back to
the breeding colonies. For their migration routes, they use three main directions: NW
to the Austrian and Italian Alps (those may head later on to France and Spain); SW
to the southern Italy, and SE to the Southern Balkanian peninsula, Bulgaria, Greece,
Turkey, Israel, reaching southern latitudes as far as Chad (Suši 2000, 2002a).
Threats:
The major causes of Griffon's decline in Croatia are as follows:
I) High vulture mortality which is caused by:
• decrease of sheep number, turn to intensive herding (winter feeding, lambing in
pens, keeping in stalls to minimize risk predation, etc.)
• large-scale indirect poisoning
• improvement of veterinary techniques which reduce sheep mortalities
• human persecution – illegal shooting to eliminate Griffons from hunting areas
(which could become an ornithological reserve).
• electrocution (every year at least two reported cases only on the island of Cres)
• human disturbance (tourism or recreational activities close to nest sites)
• replacement of native sheep by game animals (e.g. fallow deer and wild boars
cause damage on the pastures, selling of sheep in order to avoid looses by bears)
• hunting regulation which result in a reduced number of game animals available to
vultures because they are shot earlier before dying from natural causes
• habitat destruction by urbanization (building of roads and infrastructure)
• lack of implementation of existing laws (active protection in the field)
37
II) Low reproductive capacity
Additional to those threats listed above, the reproductive capacity of Eurasian
Griffons is very low and makes the species very vulnerable to losses (for example the
productivity on the island of Cres is 55-60 %, so – on average - a pair raises one
chick only every second year). Therefore, a long recovery period is necessary for the
population after being diminishing for example poisoning events.

Management Activities:
I. Past and current activities
The following conservation measures are taken by the “Eco-center Caput Insulae-
Beli (ECCIB)” as local NGO (almost without any help from the Croatian Government
with the following results:
- Establishment of a Griffon Recovery center with adequate aviary and quarantine
cages (more than 50 Griffons were brought there for rehabilitation, many of them
could be released later on to the wild)
38
- Operation of feeding stations (very intensively after 1998 and on a regular basis since 2001 with a maximum food supply of approx. 50 tons / year which directly increased hatching success)
- Building of a hide for observations and education at the vulture restaurant - Operate a scientific monitoring and research program (cooperation with the Cres
Ornithological Station of the Institute for Ornithology since 1990; 380 Eurasian Griffons have been marked with rings and wing tags since then)
- Implementation of measures for undisturbed breeding sites
- Educational program (including an exhibition about Griffons, brochures, postcards, stickers, etc.)
- Eco-tourism program in order to provide information about Eurasian Griffons, biodiversity, and to enhance involvement in protection of natural and cultural-historical heritage of the island of Cres
- Recruitment of volunteers which are actively involved in the protection, monitoring and management of Eurasian Griffons and the eco-tourism program
- Promoting a holistic approach to nature protection, local products and the preservation of the traditional methods of sheep herding to locals in order to save the food supply
II. Actions urgently needed: Activities required in order to preserve the last Croatian population of Eurasian Griffons (Sušic 2002b) should include: 1. Launch an anti-poisoning campaign with efficient measures 2. Maintain the Recovery center 3. Continuation of the Griffon monitoring program (marking, control of nest sites) 4. Telemetric monitoring of rehabilitated Griffons in order to minimize losses and
possibly identify sources of risk 5. Ensure an adequate supply of safe food through feeding sites and establish a
network of vulture restaurants 6. Minimize disturbances at the colonies by establishing “swimming fences” 7. Further sensitivity of the public (establishment of Griffon vulture-information
centers, ecotourism activities, promotion of local products and practices like extensive sheep herding)
8. Maintenance and regular cleaning of ponds as water source for sheep and Griffons
9. Modification of electricity poles in order to avoid electrocution

Some decades ago there is clear evidence that there were hundreds or thousands of
vultures nesting all over the island. Nowadays, the Griffon Vulture suffers a serious
extinction threat as a result of various factors, especially the use of poison. Today its
population size is only 6 breeding pairs at one nest site, whereas in 1980 there were
more than 20 known nesting sites.

Distribution:
The distribution of the species is focused in the western part of the French Pyrenees,
the Grands Causses area (South Massif Central), in the Vercors, Baronnies and
Verdon (Southern Alps). The colonies in the Pyrenees have been naturally restored
through conservation and management measures like the establishment of feeding
stations (currently, some feeding stations are not used anymore). The four other
populations were reintroduced and also benefit from the use of feeding stations and
the high standard of bird protection. While the French Pyrenees alpine habitats
dominate, the Grands Causses area is constituted of limestone plateaus split by
several deep gorges, particularly the Jonte and Tarn canyons. The Verdon canyon
with extreme relief energy also include plateaus, and the Baronies and Verdon areas
mainly include hills of moderate altitudes. All places include huge cliffs providing a
high availability of potential nest sites.
In French Pyrenees Griffon Vultures feed on wild or livestock animals and they find
carcasses directly in the field. In the reintroduced populations, they feed mainly on
feeding places (mostly sheep). It is important to note that in the Grands Causses
area, farmers may be allowed to manage their own feeding places due to a new
veterinary legislation set up in 1998. Recently, an updated information of French
vulture populations has been published in Terrasse et al. (2004).

Distribution: Georgia has an area of 70 000 km² with a habitat composition of 40% woodland,
30% developed areas and 30% undeveloped areas. Survey data collected over the
past 10 years in Georgia and adjoining areas in neighbouring countries showed that
Griffon Vultures (Gyps fulvus) occur only in areas that are undeveloped by humans,
but which hold supplies of livestock. The species’ year-round activity range can be
defined as an unfragmented open landscape between 1300m and 2500 m a.s.l. with
an annual rainfall of <800 mm and, alternatively, below 1000 m a.s.l. with an annual
rainfall of <400 mm. The surveys also showed that locations of nest sites and the
foraging range of breeding Griffon Vultures were significantly correlated with the
year-round ranges of livestock. Griffon Vultures are common in areas which are used
by livestock; however they are very rarely observed in the same areas during
wintertime when those habitats are abandoned by livestock. All this suggests that
Griffon Vultures in Georgia feed mainly on dead livestock. Moreover, differences in
47
the breeding success of various colonies underline the importance of livestock: In
lowland breeding grounds (at 200-800 m a.s.l.) where large numbers of wintering
livestock are present during the early nesting season (a period from hatching to
fledging) but not during the later nesting season from May through September (the
livestock graze on distant pastures then), only <50% of the Griffon Vultures are
successful in raising fledglings. In contrast, in the highland breeding grounds (at
1300-5000 m a.s.l.) where Griffon Vultures start their breeding season with only small
numbers of livestock present, the number of pairs that hatch chicks is much lower
than in the lowland breeding sites but >80% of the hatchlings fledge because food
supply greatly increases with the arrival of summering livestock in May.
In the whole Caucasus, including Georgia, the size and location of livestock pasture
grounds changes seasonally due to the movements of livestock. These movements
can be among settled areas (villages and towns) or they may vary because
herdsmen seek for snow-free pastures and good grazing grounds resulting in
wintering grounds in the dry lowlands and summering grounds in highlands.
Numbers of breeding pairs of Griffon Vultures have declined over the past 10 years
by 12%. It is unlikely that this decrease is linked to the mysterious disease and crash
of Griffon Vulture populations as observed in Asia (the typical symptoms as reported
from there like “head-drooping” behaviour have never been observed in Georgia);
Rather, the decline in Griffon numbers is caused by a dramatic decline in sheep
numbers as their main food supply (see Fig. 1) which can be observed since the
breakdown of the ex-USSR. In Soviet times sheep farming was well subsidized. In
contrast to sheep, other domestic animals have shown increase.

Legal protection of the species:
Griffon Vultures are legally protected under Ministerial Decision 414985/1985 and
listed as Vulnerable in the Greek Red Data Book (Handrinos 1992). 100% of the
colonies of mainland Greece and Cyclades are protected as Special Protected Areas
(SPAs), while more than 80% of the colonies of Crete are protected as SPAs. The
Greek list of Important Bird Areas (IBAs) covers 100% of the population of the
species in mainland Greece and Cyclades, and 90% of Crete. It should be noted that
the enforcement of the above legislation is extremely inadequate and in general very
few measures have been taken for the species up to now. The last couple of years
new SPAs and Wildlife Refuges are being designated, taking into consideration the
conservation needs of the Griffon Vulture.

51
Distribution:
Griffon Vultures are found in open, hilly and mountainous areas consisting of low hill
habitats with garrigue and open maquis to high alpine areas. They are optimal
foraging areas as long as a sufficient level of grazing by domestic ungulates is
guarantied. The species requires huge cliffs, with plenty of recesses and free from
human disturbance. It may even nest in sea cliffs and on small offshore islands.
Presently, there are 9 colonies situated at two relatively isolated areas of mainland
Greece. One in NE Greece (Thrace) closely related to the SE Bulgarian population,
and another one in W Greece (western Ipiros and Aitoloakarnania prefecture), and
an isolated colony in central Greece (Larisa prefecture). In contrast to the mainland,
the Griffon Vulture populations on the Greek islands are stable, with 34 colonies on
Crete and 2 on the central Cyclades.
At least 60% of the species range in mainland Greece has been abandoned since
1990. The species does not breed any more at the Peloponnese, Sterea Ellas
(except Aitoloakarnania prefecture), Thessaly (except Larisa prefecture), Macedonia
and Ionian islands. During this period 13-15 colonies were abandoned in mainland
Greece and Ionian islands. Presently the range of the GV is constantly shrinking in
mainland Greece, and many colonies have been deserted at the edge of the species
distribution. Unless immediate action is taken, this trend will continue especially in
central and western Greece, dramatically minimising the species' population and
range in the near future.
It seems that Griffon vultures have survived in parts of Greece where:
• less poisoned baits are dispersed, because of the absence of large predators
(wolves, jackals, foxes). This is obvious at Cyclades and Crete where foxes,
jackals and wolves are absent. Also at western Greece, GV colonies exist in
places where the wolves are mostly absent and there is obviously no intensive
use of poisoned baits for the control of foxes. Unfortunately, the recent range
expansion of wolves in several parts of mainland Greece has resulted in an
extensive use of poisoned baits with - most probably - very negative effects for
the Griffon Vulture population.
• food availability and accessibility is sufficient due to the maintenance of traditional
stock rearing practices and large numbers of domestic animals. These places
52
include the last resorts of Griffon vultures of Greece at large islands (Crete and
Naxos), Ipiros, Aitoloakarkania, and parts of Thrace.
• infrastructure is less developed (road network, etc) and human pressure is low.
This is presently valid for the mountainous area of Thrace and parts of Ipiros.
• vulture restaurant(s) are operating on a regular basis, and supported by
simultaneous and effective protective and awareness measures, applied over a
long term. This seems to be an important reason for the survival of the GV
population at the Evros prefecture and, consequently, the Thrace region. The
operation of another vulture restaurant (but not on a regular basis) at Larissa
prefecture, has been helpful for the maintenance of an isolated GV colony in
Thessaly region. However, this seems insufficient for a long-term survival of this
colony, unless further action is taken.
The present situation of the mainland population must be considered as much more
critical than some years ago and demands immediate and urgent action. The
implementation of high priority measures is handicapped by a fundamental
unwillingness and incapability of the federal authorities to protect Greece’s natural
heritage and to enforce relevant legislation. These obstacles can only be overcome
by an intensive, constant and coordinated conservation efforts of NGOs, awareness
of the local communities and relevant authorities, and an immediate funding of the
most important measures.

Nevertheless they are a factor of constant importance, especially when domestic ungulate carcasses become less available to GV. 4 Target species are mainly wolfs (that have extensively recolonized areas during the last decade), foxes and jackal (extinct in many places). Secondary targets are other species as stray dogs, martens, ravens, Golden eagles, Bonelli's eagles, etc. 5 possibly of great importance(by direct shooting or bullets swallowed with the food items)
Important note: a solid evaluation of certain threats was not possible in many cases due to a lack of detailed and systematic monitoring data of most colonies in mainland Greece.

Conservation of Griffon vulture in Greece
Few NGOs and one Institute are working on the conservation of Griffons vultures.
These are: Hellenic Ornithological Society, World Wild Fund for Nature Greece –
Dadia Project that is being activated at Dadia area, Hellenic Wildlife Rehabilitation
Center and National Agricultural Research Foundation. Besides extensive research
on the species has been undertaken in Crete by Stavros Xirouchakis.
Furthermore there is a Life project including conservation measures for the protection
of Griffon vultures at Stena Nestou, undertaken by the Society for the Protection of
Nature and Ecodevelopment (EPO). Finally there is an one year project for the
monitoring and conservation of the Griffon vultures at Arakynthos mountain,
undertaken by the Immediate Intervention for the protection of Nature.

which presently includes NE Italy (Forgaria nel Friuli - Udine) and Central Italy (two
sites in the Abruzzo-Province L’Aquila (Allavena pers. com.; Genero in prep.).
Another reintroduction project is in progress in Sicily (S Italy), where some birds have
recently been released (Lo Valvo pers. com.) but they are presently not breeding.
Additional reintroduction projects are planned in Calabria (birds still in captivity;
Pandolfi: pers. com.) and in the Central Alps (Trento region: Genero in prep.).

Distribution:
Griffon Vultures have been recorded mainly in the western parts of the country,
especially along the western edges of the mountain ranges extending in a S-N
direction along the rift margins. The only breeding colonies are currently known from
Dana Nature Reserve in the SW Jordan (up to 12 pairs). Nevertheless, birds are
often being recorded in other parts of the highlands of SW Jordan, e.g. at Petra, and
in the extreme north at Wadi Al-Yarmuk. Breeding occurs in rocky mountains with
deep gorges and/or high cliffs with ledges, in SW Jordan mainly on sandstone cliffs,
climate is arid to semi-arid Mediterranean, vegetation being mainly of steppe
character, the same habitats which are usually inhabited by Nubian Ibex and Rock
Hyrax. The habitats are subject to grazing by goats and sheep, sometimes kept by
locals in large herds of up to 100 animals each. These domestic animals are
currently believed to be important as a food source for the vultures, as the wild
animals e.g. ibex and gazelles have become extremely rare. Overgrazing may have
negative effects on the long run.

Distribution:
The Griffon Vulture is distributed in various areas of the country:
1. Demir Kapija Gorge: 18-20 breeding pairs, situated in south-eastern Macedonia
along the river of Vardar. Huge limestone cliffs with Mediterranean vegetation
(Juniperus excelsa, Juniperus oxicedris, Phylirea media, Quercus coccifera and
others). Closely, large open areas with large number of wintering sheep herds
occur. To the south is the Kozhuf Mountain range where the sheep herds graze
during summer. Additionally, the vultures of these colonies have access to the
Negotino rubbish dump where they can feed on slaughter offal.

Serbia
Bulgaria
69
2. Tikvesh area: 9-11 pairs breed on huge limestone cliffs. The area is situated in
the southern part of Macedonia, along the river Crna and the Tikvesh reservoir.
The vegetation is similar to the one described for Demir Kapija with additional
Black Pine forests (Pinus nigra) and single Arbutus andrachne trees. There is a
vital wolf population in the adjacent region and lot of sheep in the area of Mariovo.
In this area also Black, Bearded and Egyptian Vultures occur.
3. West Mariovo: 2-3 pairs are breeding in this wide gorge along the Crna river
(rocks of volcanic origine). Silicate cliffs with scarse tree vegetation are
characteristic for the landscape.
4. Raets Gorge: 0-2 pairs breed there irregularly. Medium sized limestone cliffs
along a small river. The vegetation is similar to Demir Kapia. 2003/04 was
breeding records.
5. Babuna Gorge: 0-2 pairs breed there irregularly. A small limestone cliff with many
caves. The gorge is situated in the lower Babuna River Valley next to the town of
Veles. The vegetation is similar to Demir Kapia. The vultures from this colony use
the Veles slaughterhouse offal dump for feeding. 2003/04 was breeding records.
6. Bogoslovets: 0-5 pairs breed there irregularly. The gorge consists of medium
sized mergillite cliffs along the Bregalnitsa river in central Macedonia. A lack of
food during the summer season due to its traditional use for winter sheep grazing
(completely flat terrain) is the likely reason for the irregular breeding in this area.
However, the vultures use the slaughterhouses of Sveti Nikole and Shtip for
foraging. 2003/04 was breeding records.
7. Ratkova Skala: This colony has 3-4 breeding pairs and is situated in the north-
eastern part of Macedonia in the Osogovo mountains. The cliffs are medium sized
and consist of volcanic rocks. There Griffons use the open flat area of Ovche Pole
for winter foraging and the Osogovo Mountains during summer when the sheep
graze on the alpine pastures.
8. Matka Gorge: A small "colony" along the Treska river in Northern Macedonia
close to Skopje with 1 breeding pair on huge limestone cliffs
70
9. Shar and Korab Mountains: High mountains where Griffon Vultures are only
summer visitors because the mountains are used by sheep exclusively as
summer grazing grounds (up to 1,000,000 sheep not long ago).

3.14 The Situation of the Griffon Vulture in Morocco
Said Hajib

Projet de co-operation Morocco Allemande
“Assistance à la Gestion des Ressources Naturelles”
The Gyps fulvus is on the brink of extinction in Morocco, due to the use of poison to
destroy feral dogs, poaching, disturbance and destruction of nests. Historically, this
species nested all over the rocky cliffs in Morocco mountains. Currently , its
population should not go over 10 nesting couples in the whole country. Nevertheless,
the species has been observed regularly crossing the country during winter in small
groups. Almost 1000 birds cross the Gibraltar every autumn. These birds could be
observed in Morocco from October to half of May. They are coming especially from
the expanding population inhabiting in Spain. According to Garrido et al. (in press)
the species is completely absent in Northern Morocco and only migrants from Spain
have been recorded. Groups of griffons are recorded every year between October to
December. A few recoveries of Spanish birds have been recorded.
Although, the Gyps fulvus is considered as a protected species in Morocco, no
concrete actions have been done so far to restore it. The creation of some protected
areas including the vulture nesting cliffs has been achieved, but it is not sufficient to
protected the species foraging sites. The forest department is planning to reintroduce
the Gyps fulvus in the framework of protected area management project financed by
the GEF (World Bank).

Distribution:
The species is widely distributed all over the Iberian Peninsula. However, a wide
Atlantic corridor is not suitable Griffon habitat and thus Portugal is only partly settled
by Griffon vultures. The species distribution in Portugal on the large rivers basins:
Duero (43,1% of griffon population), Tajo (56,5%) and Guadiana (0,4%) and is
connected to the population of Spain.
The Guadiana Basin was re-colonised in 1999 after more than twenty years without
vultures. In 1989 (1st census in Portugal) 62-72 breeding pairs were recorded and 7
years later the population increased to 155-159 pairs. The success of the griffon
vulture in Portugal is linked to the traditional farming practices of leaving carcasses in
the field providing a good food supply for vultures.

Distribution:
The species is widely distributed all over the Iberian Peninsula except the NW
(Galicia), a wide Atlantic band (most of the Portuguese country) and some
Mediterranean regions (south of Valencia and east of Andalusia). Most important
populations are located in the western part of the Pre-Pyrenees, NE of Castilla León
and in southern Spain (Cádiz, Extremadura and Salamanca). From Salamanca the
species range extends into Portugal through the large rivers (see Portugal).
However, 98.5% of the Iberian population lives within Spain. 80% of the population
inhabits five autonomous regions: Aragón (25,3%), Castilla & León (23,7%),
Andalusia (12,5%), Navarra (11,5%) and Castilla la Mancha (7,2%). Another 7,2% of
the population includes the following 12 provinces (listed in decreasing order):
Navarra, Burgos, Huesca, Teruel, Cádiz, Zaragoza, Segovia, Cáceres, La Rioja,
80
Portugal
Spain
Morocco
France
81
Guadalajara, Salamanca and Soria. Four provinces have been recolonised during
the last 10 years: Almería, Barcelona, León and Murcia. Recently (2000-2002), a
reintroduction project is under ways in the Alicante province (Del Moral & Martí,
2001).
The first National Census was carried out in 1979 (SEO 1981). During the years
1979-1989 (Arroyo et al. 1990) a 135% increase was detected while the increase
during the following decade was 130%.
Almost all habitats with large livestock numbers are being used. Many vultures forage
on intensively used farmland (mainly pigs). Feeding points, which are actually illegal),
are the main food supply there. However, food provision may turn out to be a major
threat in the short future due to the EU-regulations following the BSE crises
(322/2003 Decision). In this context, an European regulation on food provision for
carrion eating birds is an urgent requirement and must be approved because vultures
are largely depending on cattle and sheep (species that are considered to contain
specific risk material in the context of the BSE problem).
The other threat for vultures in Spain is poisoning. A great increase has been
detected during the past years (Hernandez 2000). Poison is used in order to reduce
predators of small game, attacks of wolves on livestock and, recently, attacks of
griffons on live livestock (Camiña et al. 1995, Camiña 2004).

Distribution:
Porter (1991) described the status of the Griffon Vulture as a “Regionally Significant
Breeder” as more than 20% of the regional population or 20% of the regional range
of the eastern half of the West Palaearctic (including the whole of Iran) occurs in
Turkey. Most of the population is resident in south, south-eastern and eastern Turkey
with some remnants in western and northern Turkey, where the Griffon is less
common than the Eurasian Black Vulture Aegypius monachus (Heredia et al. 1997).
However, the species is absent along the Black Sea coast (Kasparek 1992; Bilgin &
Kasparek 1996). In 1982 Gensbøl (1987) estimated the Turkish population at
between 500–1000 pairs and referred to a decreasing trend. Both, Arroyo (1994) and
Bilgin & Kasparek (1996) estimated the Turkish population at between 100 and 1000
pairs; Arroyo (1994) further mentioned a moderate decline. However, Kasparek
(1992) indicated that the most western colonies near Izmir and the Meander Delta

were already abandoned in the first half of the 20th century. It was further suggested
that the Griffon Vulture had undergone a significant decline until the 1960s and
thereafter the population had stabilized at a low level. Recent field studies revealed
that the actual population of Griffon vultures in Turkey is not less than 300 and
probably not exceeds 500 pairs (Vaassen, 2002a; Vaassen & Aykurt, 2002).
Preference has been found for areas with marginal cultivation and, if available, only
patchy forest. The damming area (mainly Atatürk Barajc, Keban Barajc) in central-
east Turkey discontinuousness the distribution of Griffon vultures in SE and S
Turkey. Suitable cliffs or breeding habitat are found very commonly in Turkey,
however food resources and surrounding habitat are a limiting factor. Foraging areas
are threatened by overgrazing, agricultural intensification in the whole western half as
well as in south-eastern Turkey and threatened by afforestation mainly in NE Turkey.
Poisoning seems to be the main threat of griffon vultures in Turkey.

4. Aims and objectives
4.1 Aims The remaining populations in the eastern European / Mediterranean range suffer an
increased vulnerability due to:
• Isolated subpopulations
• Very large foraging areas (local and non-local threats)
• Very low effective population sizes
• Presumably very few genetic interactions
• Low natural reproductive rate
• Slow generation cycle
• Low potential for natural re-colonization
• Intensive philopatric behaviour
Therefore, management and conservation activities require a pan-Eurasian scale.
The aim of this Action Plan is to reduce the population decrease of the Eurasian
Griffon Vulture in the Eastern European/Mediterranean Range and to inverse current
trends in population dynamics. Over the long term, a self-sustaining (meta-)
population should be achieved with a re-colonization of the former range (where
habitats is still suitable). We also expect highly beneficial effects for all other vulture
species in the geographic scope of this Action Plan.
4.2 Objectives Although certain aims and objectives may affect more than one of the following
categories, we structured them in i) conservation and management, ii) monitoring
and iii) research needs. This seems appropriate because their implementation will
involve different NGOs and governmental institutions according to their specific
competence.
87
4.2.1 Conservation and management
Conservation and management needs address the following issues:
Poisoning – essential
• Safe food supply (feeding stations)
• Effective protection of livestock against predators
• Law enforcement
• Implement political pressure on a EU-Level
• Establish a anti-poisoning working group
• Control of poisons and effective regulations
• Anti-poisoning campaign and public awareness
• Monitoring of poisoning events and food quality (identification and analyses)
• Ban of lead bullets
Poisoning is a complex problem which addresses a wide spectrum of issues. These
include the reinforcement of existing laws, control of the use of poison and
implementation of effective regulations, an anti-poisoning campaign with profound
education about the ecological consequences involved in the use of poison and the
ecological role of vultures, the ban of lead-bullets for hunting (feeding from remains)
and the protection of livestock against natural predators as an alternative to poisoned
baits (suitable guarding dogs can be an effective measure in this context).
Protection of habitat and food supply - high
• Feeding stations for enough food supply
• Law enforcement: EU-restrictions, veterinarian and biological needs
• Promotion of traditional land use / restoration of sustainable livestock
numbers
• Restoration of populations of wild ungulates
• Control of visitor flow / sporting activities
• Restriction of urbanisation and industrial exploitation
88
The supply of safe and sufficient food can currently only be guaranteed by artificial
feeding sites (“vulture restaurants”) in most parts of the Eurasian range. As most
vulture species are depending on domesticated livestock anyway, it makes not such
a big difference if food supply is provided in a dispersed manner through natural
mortality causes or at specific sites which have the big advantage of a controlled
operation (and additionally for monitoring purposes). Such feeding sites are widely
accepted in other geographic regions (for example South Africa). However, within the
context of the BSE crises, it is particularly important to establish standards for an
appropriate operation of such feeding sites at an European level.
For the maintenance of natural foraging behaviour which was of special importance
for the evolution of vultures and for some conservation biologists also desirable from
an “ethical” perspective, more natural feeding habits should be aspired. Therefore,
the promotion of extensive livestock farming, especially transhumance practices, are
important and can even be interpreted as a co-evolutional result between traditional
forms of human land-use and vultures and other scavengers. For the same reason,
the restoration of wild ungulate populations is important. Those have greatly been
decimated by over-harvesting (southern and south-eastern Europe) and due to
questionable forest management policies (central Europe).
Disturbance has been documented as the cause for the extinction of some breeding
colonies and the abandonment of frequently cliffs used as roosting sites. Therefore,
the control of recreational and sporting activities close to breeding sites and other
suitable cliffs such as climbing, paragliding, curiosity and bathing/diving (on
Mediterranean islands) is an important issue. Basically, restricted access is only a
matter of local and temporal requirements. In few occasions, mining activities have
been reported to be critical in this context (for example for Bulgaria). Building of
infrastructure and urbanisation can result in a severe reduction of habitat suitability in
sensitive breeding or foraging areas.
Powerlines (electrocution and collision), overhead cables, wind turbines - high
• Modify existing electricity poles and wires with protective devices
• Implementation of safe electricity pole design
• Avoid further buildings of overhead cable structures
89
• Optimised wind turbines (design and location)
Losses caused by electrocution or collision, overhead cables and wind turbines can
be substantial. Therefore, the design of safe electricity poles is an important measure
and adequate constructions can eliminate any risk. However, precaution measures to
avoid collision with over-head cables are much more difficult and will always
represent a certain mortality risk. In this context, urbanisation of remote areas can
have adverse effects on vulture populations. The same holds true for wind turbines
which have caused huge losses at various places (for example in Spain). Efforts
focussing on an optimised design of such structures have not been very efficient in
reducing mortality rates so far.
Illegal Shooting - medium (locally high)
Public awareness in general – medium
Reintroductions / Restocking activities - currently low (potentially high)
At present, restocking and reintroduction activities do not make much sense as
mortality causes are yet not eliminated. Therefore, the EGVWG agreed on a common
decision that any reintroduction or restocking activity must be in accordance with the
corresponding IUCN guidelines. Consequently, the importance of such activities is
currently rated as “low”. However, as vultures have strong philopatric habits, a re-
colonisation of vacant habitats of their former range will be ineffective and last
comparably long. Therefore such activities can play an important role for the long-
term restoration of the Eurasian Griffon Vulture population. Concrete and actual
plans for reintroduction exist for the Carpathian basin (Hungary, Rumania, Slovakia -
Dudas & Vegvari 2002):
Taking of Eggs – low
90
4.2.2 Monitoring
• Marking Individuals
• Population trends (breeding pairs, productivity, no. fledglings, no. at feeding
sites)
• Pathological monitoring of live and dead birds (mortality causes)
• Central database
• Habitat suitability / limiting factors
Monitoring of population trends, breeding success, movements of marked birds and
mortality causes is essential and an urgent requirement in order to set (or correct) the
adequate management priorities. The corresponding objectives include standardized
and coordinated Marking Program, sampling of population trend, breeding success
and movements of marked birds, integrated Data Base (one coordinator per country,
synchronized copies for all users)
The EGVWG established basic standards for a coordinated ring-marking and wing-
tagging project on earlier meetings, and an integrated database is currently being
established to guarantee standardised data. This data-base will be handled by
national coordinators and data-integration and re-distribution will be managed
centrally by French colleagues (F. Sarrazin, French team). Local copies of the
database are provided for every group involved in monitoring to guarantee quick data
access. Due to the risk which is imposed by the population crash of Gyps vultures on
the Indian subcontinent, a special monitoring concern has to be focussed along
potential Eurasian migration routes.
4.2.3 Research needs
• Population Viability Analyses
• Space / habitat use patterns (population interactions, risk identification,
Juvenile dispersal)
• Evaluation of management priorities for present and potential habitats
• Medical and toxicological research (post mortem examinations)
• Analyses of genetic variation (Population structure, reintroductions)
• Final confirmation of causes for the crash of Gyps-populations in India
91
Currently, there are considerable gaps in our knowledge of many aspects of Griffon
Vulture biology which limit our capabilities concerning certain management aspects.
One of the most relevant aspects in this context addresses population interactions
throughout the distribution range. Various observations of marked individuals give an
idea about large scale movements, juvenile dispersal and migration routes. However,
we have currently no idea if these movements result in interactions on a population
level such as gene flow. Therefore, genetic analyses of different populations are of
great importance. They are also relevant for potential restocking and/or reintroduction
projects as the diversity of the gene pool will also have consequences for the
decision which individuals are suitable for being released to the wild in the Eastern
European/Mediterranean range. Currently there are 3 research groups working on
genetic aspects (in France, Germany and Israel).
Besides the knowledge on gene flow, a more systematic monitoring of large and
short scale movements is of high importance. Such data can be collected using
various telemetry techniques (satellite-, GPS/GSM and VHF-telemetry) and will
deliver valuable data on habitat utilisation, risks and mortality causes but will also
give a clearer pattern on juvenile dispersal and migration corridors. Currently, a
research initiative is starting (cooperation between Salzburg and Vienna Zoo, the
Friuli Griffon Vulture Reintroduction Project and the ornithological station Cres) where
4 units of GPS/GSM telemetry units will be disposed on birds trapped during juvenile
dispersal which will deliver both, accurate positions, large coverage and high
temporal resolution.
A thorough analyses of mortality causes (post-mortem examinations) and of the
ultimate cause of the Gyps vulture population crashes in Asia will also be of utmost
importance for Griffon vulture research.
4.3 Logistic aspects • Optimum information flow between groups
• Coordinated marking and tagging program
• Monitoring Network
• Feeding site management (Network needed)
• Education
92
The EGVWG as a working group has very limited logistic and financial resources. We
see our capabilities primarily in providing a functioning platform for information
exchange, expertise and know-how. Therefore this Action Plan focuses more on the
relevant objectives than on concrete actions and the appointment of responsibilities
to certain NGOs, institutions and groups. However, several EGVWG members do
have resources for efficient monitoring, research and management.
For the implementation of this Action Plan, intensive cooperation at International level
is an essential requirement. A Balkan Vulture Initiative established as a joint venture
between the Black Vulture Conservation Society (BVCF), the Frankfurt Zoological
Society (ZGF), the Foundation for the Conservation of the Bearded Vulture (FCBV),
BirdLife International, La Lige pour la Protection des Oiseaux (LPO) and the Royal
Society for the Protection of Birds (RSPB) is currently under ways and can play an
important role for the implementation of this Action Plan. An agreement on
