1 INTRODUCTION

1.1 The TANBREEZ Project

The TANBREEZ project includes the development, operation and ultimate reclamation

of an open pit Zirconia, Rare Earth Elements, Yttrium, Niobium, Hafnium and Tantalum

mine at Killavaat Alannguat (Kringlerne) in South Greenland. Killavaat Alannguat is

about 20 km north-east of Qaqortoq and 12 km south-west of Narsaq.

The minerals will be mined at two sites: Mine site 1 at about 450 m altitude on top of

Killavaat Alannguat and Mine site 2 at the shore of the fjord. Mineral concentrates will

be produced with an on-site processing facility. Fostersø on the Killavaat Alannguat

plateau will be used for deposition of tailings and waste rock. The concentrates would

be shipped of-site by ship to a facility for further processing.

1.2 The aim of the report

It is a requirement of The Bureau of Minerals and Petroleum (BMP) under the

Greenland Self-government that an Environmental Impact Assessment (EIA) Report is

prepared when a company plans to exploit a mineral deposit in Greenland (BMP 2012).

The present report aims at providing essential background information for the EIA

Report, regarding the natural environment of the study area.

1.3 Definition of scope and data collection

Based on the footprint of the planned mining project, a potential impact area – in the

following termed the “Study area” - was initially defined. The extent of the Study area is

shown in Figure 2.1. The scope of work has therefore been to draw together and

present all existing information on the terrestrial and marine flora and fauna from this

area. This information will subsequently feed into the EIA process.


Figure 1.1 Study area at Killavaat Alannguat

This study has primarily been a literature study where data from published information is

presented. However, observations made by Orbicon staff during the environmental

baseline studies in the area between September 2007 and July 2010 are also included.

In connection with the literature study and the field work particular attention has been on

identifying and collecting information on Valued Ecological Components (VECs) which

are the particularly sensitive and/or important elements of the ecosystem of the project

area. This includes species of commercial value as well as species of conservation

concern in Greenland. For the purpose of this study the following Valued Ecological

Components (VECs) were identified:

White-tailed eagle Haliaeetus albicilla

Arctic char Salvelinus alpinus


1.4 The structure of this report

The report is structured as follows:

To provide a setting for the chapters on the natural environment the report

starts with brief accounts on the physical environment of the study area.

Chapter 4 describes the vegetation of the study area with focus on the key plant

communities and to what extend rare and threatened plant occur

Chapter 5– 8 cover the fauna including all mammal and bird species that are

known to be either resident in the study area or regular visitors. In addition,

information on freshwater fish and marine fish of commercial value is provided.

Chapter 9 gives an overview of the species, habitats and sites of special

conservation concern.


2 THE PHYSICAL ENVIRONMENT

The landscape in South Greenland is characterized by relatively high and steep

mountains inland and low islands and peninsulas in the coastal area. This landscape is

largely formed by the ice, which has also carved the long, narrow fjords. The entire area

was covered by ice during the last glaciations (the Weichel/Wisconsin) until about

11000 years ago and the landscape is therefore highly influenced the glacial processes

such as erosion, transport and sedimentation (Langager & Lemgart 1988).

The Killavaat Alannguat is a mountainous area along the south-eastern shore of the

Kangerluarsuk Fjord (Figure 3.1). The inner section of the fjord is mostly steep-sided

and surrounded by mountains rising to 700 – 1 000 m with the spectacular Killavaat

(Redekammen) mountain to the east rising to 1 200 m. The Lakseelv (Salmon River)

has its outlet at the bottom of the fjord, about 2 km North-east of the mineral deposit

(Figure 4.1). The inner parts of Kangerluarsuk fjord near Killavaat Alannguat have a

maximum depth of 60 meter depth but further south the depth is up to 200m.

Killavaat Alannguat is part of the Illímaussaq intrusion, which include the formations at

the northern parts of the Kangerlursuk Fjord. The mountains that surround the intrusion

consist mainly of granite.

Figure 2.1 The Killavaat Alannguat with Mine site 1 at the centre and Kangerluarsuk Fjord to the right. The Ivaangiusaq Kangileq mountain (top centre) behind Killavaat Alannguat rises to 805 m


2.1 Climate

At a regional scale the weather in South Greenland is mainly influenced by the North

American continent and the North Atlantic Ocean. But the local climate is also heavily

influenced by the Greenland Inland Ice. Another key factor is the all year round low sea

surface temperature which is causing the South Greenland waters and coasts to be part

of the arctic zone with average summer temperatures below 10 degree C.

Qaqortoq, 20 km South-west of Killavaat Alannguat, is situated close to the open coast

and is under influence by an oceanic weather type with cool summers and relatively

mild summers. The average January temperature in Qaqortoq is – 5.5 degree C, while

the average temperature in the warmest months (July and August) is 7.2 degree C (DMI

2012).

Further inland, the weather type is more of a continental type and in South Greenland

average summer temperatures can locally exceed the 10 degree threshold, which limit

the arctic region. This includes Narsarsuaq, 35 km north-east of Killavaat Alannguat.

Here the average January temperature is – 6.8 degree C, but 10.3 degree C in July

(DMI 2012).

The weather regime in the Killavaat Alannguat area takes an intermediate position

between Qaqortoq and Narsarsuaq. This means that Killavaat Alannguat lies within the

Arctic climate zone, with cool summers and cold winters. The temperature recorded by

the metrological station at Killavaat Alannguat between June 2010 and October 2011 is

shown in Figure 3.2. The impact of relatively warm foehn winds (see below) even during

mid-winter are very obvious and push the temperature above zero for a few hours even

during mid-winter.

Figure 2.2 Temperature (degree C) recorded by the metrological station at Killavaat Alannguat between June 2010 and October 2011


The annual precipitation is also most likely somewhere between the 858 mm recorded

in Qaqortoq and the 615 mm recorded annually in Narsarsuaq.

Gale force winds (above 13.8 m/s) are common in South Greenland in particular in

winter. The wind speed recorded by the metrological station at Killavaat Alannguat

between June 2010 and October 2011 is shown in Figure 3.3. High winds are recorded

all year but wind speeds above 40 m/s are only recorded during winter.

So called Foehn winds are outbursts of dry and relatively warm air. Such winds arise

through adiabatic compression of the air sweeping down from the inland ice cap. Its

relative humidity drops to 30-40% and the temperatures rises up to 15-20 degrees C

within an hour and remains very high for up to a day or two. The effect of the Foehn

wind is particularly marked in winter, when it results in rapid melting of the snow. Foehn

winds are quite common in southern Greenland, including the Killavaat Alannguat area.

Figure 2.3 Wind speed (m/s) recorded by the metrological station at Killavaat Alannguat between June 2010 and October 2011

2.2 Sea ice

Three types of sea ice occur in Kangerluarsuk Fjord:

Short-lived fast ice may occur in the inner part of the fjord during winter. This

type of ice cover is extremely variable both during the winter period and

between winters. In recent years fast ice has mostly been limited to the heads

of fjords with the fjords otherwise ice-free during winter.


Small icebergs and growlers originating from glaciers in Brede Fjord and

elsewhere occasionally enter the Kangerluarsuk Fjord.

Multi-year sea ice / drift ice (Storis) flows southwards along the east cost of

Greenland with the East Greenland current, turns westwards at Cap Farewell

and then northward along the West Coast of Greenland. In some years “Storis”

fill up the mouths of the larger fjords of South-west Greenland during March and

April. When large amounts of pack ice enters the area from Cape Farewell

between February and July the entrance of Narlunaq/Skovfjord fills rapidly, but

only in south winds does the ice enter the fjord. Storis only very rarely enter

Kangerluarsuk Fjord.


3 VEGETATION

In South Greenland the vegetation is largely determined by temperature and

precipitation which generally follows an oceanic-inland/continental gradient and an

altitude gradient. Along long and narrow fjords, such as the Kangerluarsuk Fjord, this is

very obvious as one moves from the outer fjord where vegetation growth is suppressed

by cold ocean currents, drift ice, salt spray, and wind to the head of the fjord far inland

where the vegetation below 200 m altitude, with south-facing exposure, locally develop

into dense one meter high birch and willow scrub.

A survey of the distribution of plant communities of the study area was carried out in

1974 (Rose-Hansen et al. 1977). In 1977 – 1981 further studies of the vegetation were

published in Thorsteinsson (1983). Although these studies were carried out several

decades ago it is believed that the general distribution of plant species and communities

including the occurrence of vulnerable species has not changes significantly over the

years. Studies of the biodiversity in the study area between 2007 and 2010 by Orbicon

staff points in the same direction.

The Ilímaussaq intrusion at Killavaat Alannguat is unusual in having almost no

vegetation at all. Large expanses of the terrain above c. 200 altitude have no plant

cover and only very few widely scattered plants exist. Only in the lowlands (below c. 100

m altitude) close to the fjord and along the lower part of the river is a shallow band of

vegetation.

3.1 Vegetation below 200 m altitude

Around the head of the fjord and along the lower section of Lakseelv at altitudes below

300 m the vegetation is dominated by different types of dwarf shrub heath and

grasslands.

Dense vegetation is limited to a narrow band along the shore of the Kangerluarsuk Fjord

and on both sides of Lakseelv below 50 – 100 m altitude (see Figure 3.1). In this area

the following plant communities have been identified (from Rose-Hansen et al. 1977

and observations by Orbicon staff):

Dwarf shrub heath is found along Lakseelv and the shore of the head of the

fjord dominated by Crowberry Empetrum nigrum, Glandular birch Betula

glandulosa and Northern willow Salix glauca. On dry exposed slopes Common

juniper Juniperus communis is widespread.

At protected and moist sites along the northwest shore near the head of the

fjord (that is opposite the planned port facility) and along the lower part of

Lakseelv small patches of richer vegetation is found with Alpine bartsia Bartsia

alpine, Viviparous knotweed Polygonum viviparum, Flame-tipped lousewort

Pedicularis flammea, Angelica Angelica archangelica, Moonwort Botrychium

lunaria and Small-white orchids Leucorchis albida.


Figure 3.1 Dwarf heath vegetation form a narrow green belt of both sides of the lower part of Lakseelv

Figure 3.2 Small-white orchid (Leucorchis albida) among copses of willow and birch along Lakseelv


Close to the shore of the fjord north of the outlet of Lakseelv grows Scottish

lovage Ligusticum scoticum and Beach pea Lathyrus maritimus.

Up to one meter tall copses of Northern willow occur along some of the small

watercourses and scattered along Lakseelv.

Above 50-100 m altitude the dwarf shrub heath grades into a mossy heath with

some Northern willow and Glandular birch. Over 100 m altitude this vegetation

gradually becomes patchier.

Figure 3.3 Vegetation on the southeast facing slopes of Killavaat Alannguat towards the inner fjord is limited to a narrow zone below 200 m altitude

3.2 Vegetation above 200 m altitude

Above c. 200 m altitude the Killavaat Alannguat mountain has almost no vegetation at

all. This includes the slopes facing the fjord, the plateau on top of the mountain and the

land surrounding Fostersø, Månesø and the river Laksetværelv that drains these lakes.

In this area the plant cover is estimated to cover less than 2% of the land (see Figure

3.4, 3.5 and 3.6). The plants that do exist at Killavaat Alannguat include Arctic marsh

willow Salix arctophila, Lapland diapensia Diapensia lapponica, Moss campion Silena

acaulis and Purple saxifrage Saxifraga oppositifolia. Along watercourses - including

Laksetværelv - grow few scattered and small examples of Glandular birch, Northern

willow and Mountain sorrel Oxyria digyna.

4 ANIMALS

4.1 Overview

Little specific knowledge exists about the animal life of the Killavaat Alannguat area.

However, general information is available about the occurrence of mammals, bird and

fish in South Greenland. In addition, Orbicon has made observation of animals during

their fieldwork. This description of animals in the study area focuses on the best known

groups, in particular mammals and birds.

4.2 Terrestrial mammals

The mammal fauna in South Greenland consist almost exclusively of marine species

and only two terrestrial species occur; Arctic fox and Arctic hare.

4.2.1 Arctic fox

Arctic fox (Alopex lagopus) is widespread and generally common throughout Greenland.

It is the only terrestrial carnivore in South Greenland. Foxes are opportunistic feeders

and the diet includes birds but also fish and mussels found along the shore.

During the fieldwork a few foxes were observed and it is assumed that it is relatively

common throughout the study area.

4.2.2 Arctic hare

Arctic Hare (Lepus arcticus) is distributed is most of Greenland only missing in the

South-east. Numbers fluctuate from year to years, due to the winter conditions. It is

most common in north-east Greenland. Probably due to intensive hunting in South

Greenland it is mostly confined to mountainous areas in this part of the country and is

usually also very shy. Arctic hare is generally protected in May – July but hunting all

year can locally be permitted.

Sedges, grasses, and rushes as well as willow are primary food items of the Arctic hare

in Greenland.

During the field study a few hares were observed near Fostersø but it is believed that

the species occur throughout the study area in small numbers.


Figure 4.1 Arctic hare occur in small numbers in the Killavaat Alannguat area

4.3 Marine mammals

17 marine mammal species, mainly whales and seals, are present in the South-eastern

David Strait off the west coast of South Greenland (Mosbech et al. 2004). Most of the

whales and at least one seal species remain usually offshore and only occasionally

enter the fjords. This includes Blue Whale, Pilot Whale, Sperm Whale, White-beaked

Dolphin, Bottlenose Whale, Sei Whale and Bearded Seal. Killer Whale occasionally

enter the fjord mouths (Mosbech et al. 2004) but are very rare in the fjords further inland

and are therefore not considered here. Similarly, the occasional Polar bear that arrive to

South Greenland with the drift ice (Storisen) between February and May almost never

make it into the fjord area before it is shot, and are consequently not dealt with here.

The three species of seal and the four whale species described below are the ones that

are either resident in the study area or believed to be regular visitors.

4.3.1 Ringed seal

This rather small seal has a circumpolar distribution and occurs in all waters

surrounding Greenland. It is generally common in Greenland waters but less so along

the South-western coastline (Rosing-Asvid 2010). It is believed to be mainly stationary

in South Greenland where it favours fjords with ice (Mosbech et al. 2004).


Ringed seals haul-out and moult exclusively on fast-ice. During winter they maintain

several breathing holes in ice. Ringed seals breed at the head of fjords where fast ice is

formed during winter. Breeding takes place from March-April to mid-May when the pups

are born in snow dens on the sea ice. It feed on a broad range of pelagic prey items,

including fish and crustaceans (Mosbech et al. 2004).

Ringed seal is subject to large scale unregulated hunting and is regularly on sale at the

local markets “brættet” in Narsaq and Qaqortoq. The take of Ringed seal has been

more or less stable since the 1960’ies at about 60-70 000 individuals (Bugge and

Christensen 2003). It is listed as “least concern” on the provisional Greenland Red List

of threatened species (Boertmann 2007).

Field work in Kangerluarsuk Fjord suggests that it is rather uncommon in this fjord.

4.3.2 Hooded seal

Hooded seal (Crystophora cristata) is a large seal which is only present in South

Greenland in part of the year. In June-July hooded seals gather in large number to

moult off the South-east cost of Greenland. Following the moulting, many of the adult

seals migrate to feeding areas off the South and West coast of Greenland and a few of

these seals also enter the fjords (Rosing-Asvid 2010). In late winter Hooded seals

belonging to this population leave the Greenland waters and swim to breeding grounds

off Newfoundland. Hooded Seals that come to West Greenland is part of the West

Atlantic population with numbers about 500,000 animals (A. Rosing-Asvid in litt.).

Hooded seals are believed to feed mainly on large fish such as Atlantic cod, Greenland

halibut and in particular redfish caught at large depths (down to 800 m or even deeper)

(Rosing-Asvid 2010).

Hunting in Greenland is unregulated. It is listed as “Least concern” on the provisional

Greenland Red list of threatened species (Boertmann 2007).

Little is known about the status of this seal in Krangerluarsuk Fjord but it is believed that

only small numbers reach the inner section of the fjord but definite information is

lacking.

4.3.3 Harp seal

Harp seal (Phoca groenlandica) is a common non-breeding visitor to Greenland fjords

during the summer months. Harp seals breed and moult off Newfoundland and large

numbers of animals from this population subsequently move north to Greenland waters

where they arrive in May. In late autumn – early winter the Harp seals leave the

Greenland waters again and return to the breeding grounds (Rosing-Asvid 2010). The

population of Harp seal is very large (about 6 million animals) and probably stable (A.

Rosing-Asvid in litt.). In Greenland the hunting is unregulated and the seals are usually

shot with rifles. It is listed as “Least concern” on the provisional Greenland Red list of

threatened species (Boertmann 2007).


Harp seal is the most numerous seal species in the South Greenland fjords during

summer when this species of seal penetrates deep into the fjord. During summer the

Harp seal typically form feeding groups of 5 – 20 animals that mostly feed on capelin in

the upper layer (down to 100 m)(Rosing-Asvid 2010).

Little is known on the status of Harp seal in Kangerluarsuk Fjord but it is believed that it

is quite common between May and October although definite data are lacking.

4.3.4 Humpbacked whale

The population of humpbacked whale (Megaptera novaeangliae) in Greenland water

has increased significantly in recent years and it is now quite common in the fjord of

West Greenland during summer where it feeds on krill and small fish e.g. capelin and

sand eels (Larsen & Hammond 2000). In some years Humpback whales also enter

fjords in South Greenland for example in 2008 where at least three different animals

were observer at Qaqortoq and Narsaq.

Humpback whale is listed as “Least concern” on the Greenland Red list of threatened

species (Boertmann 2007). Greenland is given aboriginal subsistence quotas to hunt

Humpback whales. For the period 2010-2012 the annual quota is 9 animals.

Figure 4.2 Humpback whale at Qaqortoq, June 2008


4.3.5 Minke whale

Minke whale (Balaenoptera acutorostrata) is common along Greenland’s South and

West-coast and sometimes penetrates into the outer parts of the fjords. It arrives to

South Greenland in spring and summer from wintering grounds in the Atlantic Ocean

and leave south Greenland again in November (Mosbech et al. 2004).

It is a regular visitor to the fjords of Southern Greenland and within the study area it

sometimes occurs at the Qaqortup Ikere/Julienahåbsfjorden and in Qaqortup Imaq

(Mosbech et al. 2004, Peter Hansen pers. com) where it is hunted.

It is listed as “Least concern” on the Greenland Red list of threatened species

(Boertmann 2007). Greenland is given aboriginal subsistence quotas to hunt Minke

whales. For the period 2010-2012 the annual quota is 190 animals.

No recent observations have been made of Minke whales in Kangerluarsuk Fjord but it

is probably an irregular visitor.

4.3.6 Fin whale

Fin whale (Balaenoptera physalus) is a summer and autumn visitor to South Greenland

occurring between June and October. It usually remains offshore along edges of banks

where it feed on krill and smaller schooling fish. However, it is also a regular visitor to

the fjords of South Greenland and within the study area it sometimes occurs at the

Qaqortup Ikere/Julianehåbsfjorden and occasionally even in Qaqortup Imaq (Mosbech

et al. 2004, Peter Hansen pers. com) where it is hunted.

It is listed as “Least concern” on the Greenland Red list of threatened species

(Boertmann 2007). Greenland is given aboriginal subsistence quotas to hunt Fin

whales. For the period 2010-2012 the annual quota is 10 animals.

No recent observations have been made of Fin whales in Kangerluarsuk Fjord but it is

probably an irregular visitor.

4.3.7 Harbour porpoise

Harbour porpoise (Phocoena phocoena) is a small toothed whale that occurs

throughout the year in the waters of south Greenland. It is generally quite common in

Greenland waters but most porpoises remain off shore with only a few penetrating into

fjords. Harbour porpoises feed on fish in the upper water layers.

Hunting in Greenland of the species is unregulated. It status on the provisional

Greenland Red list of threatened species is not assessed due to data deficient

(Boertmann 2007). No recent observations have been made of Harbour porpoises in

Kangerluarsuk Fjord but it is probably an irregular visitor.


It status on the Greenland Red list of threatened species is not assessed due to data

deficient (Boertmann 2007). Hunting in Greenland of the species is unregulated. It is

estimated that between 1,500 and 2,000 Harbour porpoise are shot annually

(Boertmann 2007).


4.4 Birds

The sea and coastal areas typically have the riches bird faunas in Greenland, both with

respect to the number of species and number of individuals (Bugge Jensen &

Christensen 2003). This includes birds that breed in Greenland but also large numbers

of birds from other breeding sites in the northern Atlantic that winter off the coast of

West and South Greenland. Most seabirds in Greenland are colonial breeders but no

large colonies are known from the South-west coast of Greenland between Ivituut and

Nanortalik (Boertmann 2004), that is including the study area and the neighbouring

waters.

A very important wintering area for sea birds has been identified off the coast of South

Greenland. This area attracts large numbers of Brünnich’s Guillemot, Common Eiders

and different species of gulls from Northern Greenland (eiders and gulls) and Iceland

and Svalbard (guillemots) (Mosbech et al. 2004).

The terrestrial and freshwater bird fauna in South Greenland is relatively poor in species

compared to arctic regions in other parts of Greenland, Canada, Alaska and Russia

(Meltofte 1985, Alerstam et al. 1986). For instance, only five species of passerine birds

are widespread and common in this part of Greenland.

The bird species discussed below are the ones believed to occur regularly in the study

area (breeding and/or wintering):

Terrestrial birds

4.4.1 Common wheatear

Common wheatear (Oenanthe oenanthe) occurs in most of Greenland only missing in

the North-east. The size of the breeding population is unknown but probably comprises

more than 500,000 pairs (Boertmann 2007). Common wheatear is protected in

Greenland.

Common wheatear is typically breeding in dwarf-scrub heath with large stones and

cliffs. It is migratory leaving Greenland in August-September and returning in May

(Salomonsen 1967). It is a common breeding bird along the lower part of Lakseelv.

4.4.2 Raven

Raven (Corvus corax) occurs in most of Greenland, but is rare or missing in the far

north. The size of the population is unknown but estimated to 50,000 pairs and is

probably increasing (Boertmann 2007). Raven is protected during the summer months.

Raven is found in almost all habitats. The nest is typically situated on a steep cliff-side.

It is partly migratory with northern birds moving to southern Greenland in winter. It is

common throughout the study area although less so away from the fjord. The hunting

season is from 1 September to end of February.


4.4.3 Red-winged thrush

Red-winged thrush (Turdus iliacus) is a rare and local breeding bird in Greenland found

only in a few places in South Greenland. It is most likely birds from the large breeding

population in Iceland that recently have colonised Greenland. Red-winged thrushes are

migratory leaving Greenland in winter.

A possible breeding bird was observed in dense and high scrub at the northern shore

of the Qaqortukulooq bay about one km west of Hvalsø Church on the 14 June 2010. It

is possible that this species will expand its range in Greenland further and perhaps

colonise the high and dense scrubs along the Kangerluarsuk Fjord in the future.

4.4.4 Redpoll

Redpoll (Carduelis flammea) occurs along the entire west coast of Greenland and on

the southern part of the east-coast. The size of the population is unknown but large,

probably up to 500,000 pairs (Boertmann 2007). Redpoll is protected in Greenland.

Redpoll is mainly found in areas with scrub of willow and birch. It is therefore most

common in the inland at low to medium altitude. Most redpolls leave Greenland in

August-October and return in April-May but small numbers remain in the South-west

(Salomonsen 1967).

Redpoll is common in the lowlands along the fjord and Lakseelv but has not been

recorded at higher altitudes.

4.4.5 Lapland bunting

Lapland bunting (Calcarius lapponicus) is a common to very common breeder along the

West coast and also occurs in South-east Greenland. The size of the population is

unknown but may exceed 1 million pairs (Boertmann 2007). It is protected in Greenland.

Lapland bunting is mainly found in areas with dwarf-bush heath. It is migratory leaving

Greenland in August-September and returning in between late April and early June

(Salomonsen 1967).

Lapland bunting is common along the fjord and along the lower parts of the Lakseelv.


Figure 4.3 Lapland bunting is common in the dwarf heat along the shore of the fjord and Lakseelv

4.4.6 Snow bunting

Snow bunting (Plectrophenax nivalis) is the most common land bird in Greenland

occurring throughout the country. The size of the population is unknown but probably

about 1.5 million breeding pairs (Boertmann 2007). It is protected in Greenland.

The key breeding habitat of Snow buntings is rocky terrain with scattered low

vegetation, but it is very adaptive occurring in towns as well as on isolated rocks deep

within the inland ice cap. The majority of Snow buntings are migratory but small

numbers remain in South-west Greenland. The first migrants usually arrive in March.

Departure is in September-October.

Snow bunting is one of the only breeding birds in the higher parts of Killavaat

Alannguat. However, even Snow bunting is a low density species in this area.

4.4.7 Peregrine

Peregrine falcon (Falco peregrinus) is a relatively common and widespread bird of prey

in most of Greenland and occurs along the entire west coast and at the east coast north

to Ammassalik. The size of the breeding population is unknown, but estimated to 1,000

– 10,000 pairs (Boertmann 2007). It is quite common in South Greenland. It is a migrant

that arrive in May and depart in August-November.


Peregrines typically nests on ledges on steep cliffs in the inland. It mainly feed on birds

such as Ptarmigan and gulls but also takes Snow buntings and other passerines

(Salomonsen 1967).

Several pairs breed in the Study area (K. Falk pers. comm.). No nesting sites are known

close to planned sites for mine facilities, but Peregrines have been observed quite

regularly during field work throughout the area.

4.4.8 Gyrfalcon

The large Gyrfalcon (Falco rusticolos) occurs throughout Greenland, but is nowhere

common. Gyrfalcon nests on ledges on steep cliff sides and primarily feeds on large

birds such as gulls.The population in South Greenland is mainly sedentary.

The size of the Greenland breeding population is estimated to c. 500 pairs. Due to the

small population Gyrfalcon is listed as “Near Threatened” in the regional Greenland red

list (Boertmann 2007).

No breeding sites of this falcon are known from the Study area (K. Falk pers. com) but

single birds have been observed at Killavaat Alannguat a few times during field work

between 2007 and 2010.

Figure 4.4 Young Gyrfalcon in South Greenland


4.4.9 White-tailed Eagle

The White-tailed Eagle (Haliaetus albicilla) is confined to the Southern part of

Greenland’s West coast north to the Disco Bay and belongs to an endemic subspecies.

During the 20th century many White-tailed Eagles were shot by sheep farmers and the

population declined to app. 50 pairs. In recent decades it has partly recovered as the

hunting pressure has eased, and the population is now estimated to 150-200 pairs

(Boertmann 2007). Due to the small population size the Greenland White-tailed Eagle is

listed as “vulnerable” on the regional Greenland red list (Boertmann 2007).

Greenland White-tailed Eagles are mainly found in coastal areas where they feed on

fish and seabirds. The nest is typically placed on ledges on steep cliffs. The adults

normally remain within the breeding areas throughout the year while the young birds

move to the outer coastal areas during winter. Breeding White-tailed eagles are present

at the nest from around 1. March to early September. Egg-laying typically takes place at

around 1. April. During breeding the eagles are known to be very sensitive to

disturbance.

White-tailed Eagles are commonly observed throughout the Study area and one or two

pairs probably breed in this area. However, no signs of breeding have been observed

near the proposed mine sites at Killavaat Alannguat or near the port site.

Figure 4.5 Adult White-tailed Eagle


4.4.10 Ptarmigan

Ptarmiga (Lagopus mutus) is the only gallinaceous bird species in Greenland. It is

widespread and common throughout the country but subject to marked annual

fluctuations in numbers. Ptarmigan has an open season from 1 September to 30 April.

In summer it occurs in most habitats from sea-level to hills and low mountains. In winter

it usually descends to lower altitudes. The food is entirely plant material.

It is protected during the summer months. Several Ptarmigans have been observed in

the Study area. In particular in the upland parts of the study area it seems to be quite

common.

Sea birds

4.4.11 Red-throated Diver

Red-throated Diver (Gavia stellata) is the most widespread and numerous diver in

Greenland and breed at lakes in most parts of the country. It mostly breeds at lakes

close to the sea. The diet consists almost entirely of fish. Sometimes Red-throated

divers breed at lakes without fish and therefore have to fish elsewhere.

It arrives to the breeding area in southern Greenland during May. In autumn, the divers

first move from the lakes to nearby fjords in August before migrating to the coasts of

Western Europe in September-November (Salomonsen 1967).

Although no breeding sites are known from the Study area it is likely that it breeds in the

area and fish in the fjord.

4.4.12 Black Guillemot

Black guillemot (Cepphus grille) is a widespread auk in Greenland that breeds along

most of the west coast and along the southern section of east coast. The population is

estimated to 25,000 – 100,000 pairs which could be an underestimate (Boertmann

2007). The hunting season is from 1 September to 31 March. It is usually strictly

sedentary only leaving the breeding areas when forced away by ice. It feed mostly on

small fish.

This auk does not breed in the Study area but small colonies are found in neighbouring

fjords (see Section 8.5). Birds from these colonies or from other breeding sites in South

Greenland may occasionally occur in the Kangerluarsuk Fjord.


4.4.13 Brünnich’s Guillemot

The Brünnich’s Guillemot (Uria lomvia) is by far the most common and widespread auk

in Greenland. The majority breeds in large colonies in the central part of the West coast

but small colonies are found along most of the West coast. The Brünnich’s Guillemot

has declined significantly in numbers in recent decades. A recent survey revealed that

no colonies are found near Qaqortoq or Narsaq anymore (Boertmann 2004).

Large numbers of Brünnich’s Guillemot winter off shore in South Greenland waters. This

include birds from colonies further north in Greenland, but also from Canada and

Svalbard (Mosbech et al. 2004). Most of the wintering guillemots stay offshore or near

the outer coasts and mouths of fjords where they feed on small fish. However,

guillemots also regularly occur in the fjords between October and April (Mosbech et al.

2004). Here, as elsewhere in Greenland, the wintering guillemots are hunted

intensively.

It is listed as “vulnerable” on the provisional Greenland Red list of threatened species

(Boertmann 2007) due to the large decline of the Greenland breeding population.

Brünnich’s Guillemot probably occurs occasionally in the Kangerluarsuk Fjord.

Ducks and mergansers

4.4.14 Mallard

Mallard (Anas platyrhynchos) is the only dabbling duck that regularly breed in South

Greenland. It is a widespread and relatively common breeding bird at lakes and shallow

coasts. In South-west Greenland the Mallard is mainly sedentary but move to the outer

coast in winter. It is potentially breeding along the coast of the Study area and several

Mallards have been observed during field work between 2007 and 2010. Mallard has an

open season between 1. September and end of February.

4.4.15 Harlequin duck

Harlequin Duck (Histrionicus histrionicus) is a relatively rare breeder in Greenland north

to Upernavik. A breeding population is also found in East Greenland. The size of the

Greenland breeding population is unknown but could consist of only 2,000 pairs

(Bortmann 2007). Due to this small breeding population the Harlequin Duck is adopted

on the regional Greenland Red List as “Near Threatened” (Boertmann 2007). The

Harlequin Duck is protected in Greenland.

Harlequin Ducks usually arrive to the breeding areas quite late in May-June. The males

leave the breeding area when the females start to incubate in July and move to the

outer coasts to moult. The females leave the breeding area with the ducklings in July-

August (Salomonsen 1967). Later (presumably in September-October) they also move

to the outer coasts.

During the breeding season, Harlequin Ducks feed on clear, clean streams where they

take macro-invertebrates, in particular midge (Simuliidae) larvae. The nest is typically

situated on mid-stream islands.


During the fieldwork in 2010 potential Harlequin duck breeding sites that is clear fast-

flowing headwaters of streams draining lakes were surveyed within the study area.

Potential breeding sites were identified from maps and subsequently surveyed by hiking

along the steams. One stream was surveyed from helicopter because it was difficult to

reach on foot. No Harlequin duck were observed during the surveys or in connection

with baseline field work in 2007 and 2008. Harlequin ducks are sky and difficult to

record at the breeding location and it cannot be excluded that one or two pairs were

overlooked. However, with no observation of the species during three field seasons it is

most likely not breeding in the area – and if it does it must be very rare.

4.4.16 Common eider

Common eider (Somateria mollissima) has a widespread but fragmented breeding

population in Greenland, typically breeding on small islets and skerries along the coast.

The West Greenland population was estimated to 12,000 – 15,000 pairs in 2002

(Boertmann 2007). The Common eider has declined dramatically during the last 50-100

years due to intensive unsustainable hunting, and the West Greenland population is

now listed “Vulnerable” in the regional Greenland red list (Boertmann 2007). This

Common eider has an open season but is protected during the summer months from 1

March.

Figure 4.6 Flock of wintering Common Eiders in Tunulliarfik Fjord, March 2010

No breeding colonies of eiders are known from the Study area but large numbers winter

off shore South Greenland and large flocks also regularly occur in the fjords (Figure


4.6). The majority of the wintering eiders in South Greenland are believed to breed in

Canada (Boertmann et al. 2004). Although definite information is lacking it is very likely

that flocks of wintering Common eiders sometimes occur in Kangerluarsuk Fjord.

4.4.17 Long-tailed duck

The Long-tailed Duck (Clangula hyemalis) breeds commonly at lakes, shallow coasts

and on small islands throughout Greenland. The size of the breeding population is

unknown but roughly estimated to 10,000 to 30,000 pairs (Boertmann 2007). Long-

tailed Duck has an open season between 1 September and end of February but the

number of birds shoot is believed to be small (Boertmann 2007). It arrives to the

breeding grounds in April. In September to November large numbers migrate south

along the Greenland West coast to the large banks of the South-west coast.

Non-breeding birds and males that have left breeding areas further inland sometimes

occur in the Kangerluarsuk Fjord, but breeding in this area has so far not been recorded

(K. Falk pers. com).

4.4.18 Red-breasted Merganser

Red-breasted Merganser (Mergus serrator) is a rather common species along the

Greenland South and West coast and part of the East coast. It breeds at lakes and

shallow fjords and bays. It arrives to the breeding grounds in late May and in

September-October the mergansers move to the outer coast where they spend the

winter. They feed primarily on fish.

Small flocks are quite common in the Study sites and small numbers may breed (K. Falk

pers. com).

Gulls

4.4.19 Iceland Gul

Iceland gull (Larus glaucoides) is a common and widespread gull in most of Greenland

only missing in the northern-most parts. The breeding population is estimated to

300,000 – 500,000 pairs and is probably stable (Boertmann 2007). Iceland gull has an

open season in Greenland between 1 September and 30 April but the number of birds

shoot is believed to be small.

Iceland Gull breeds on rocky shores, mainly in fjords where it typically nests on steep

high cliffs but sometimes also on low skerries. No colonies are known from the

Kangerluarsuk Fjord or other parts of the study site. The nearest gull colonies are in the

glacier fjord at Akullit Nunaat north of the central part of Brede Fjord (see Section 8.5)

(Boertmann 2004). Other colonies are known from the skerries and islands along the

outer coast (Boertmann 2004).

It is a common gull in Kangerluarsuk Fjord.


4.4.20 Glaucous Gull

Glaucous gull (Larus hyperoreus) is the other common and widespread marine gull in

Greenland. It occurs throughout the country. The breeding population is estimated to

300,000 – 500,000 pairs and is probably stable (Boertmann 2007). Glaucous gull has

an open season in Greenland between 1 September and 30 April.

Like the Iceland Gull, Glaucous Gull breeds on steep high cliffs but sometimes also on

low skerries. It often breeds in association with other seabirds. No colonies are known

from the Kangerluarsuk Fjord or other parts of the study site. The nearest gull colonies

are in the glacier fjord at Akullit Nunaat north of the central part of Brede Fjord (see

Section 8.5)(Boertmann 2004). Other colonies are known from the skerries and islands

along the outer coast (Boertmann 2004).

It is a common gull in Kangerluarsuk Fjord.

4.4.21 Great Black-backed Gull

The large marine Great Black-backed gull (Larus marinus) is widespread along the

Greenland West-coast north to Upernavik. The breeding population is estimated to

3,000 – 5,000 pairs and increasing (Boertmann 2007). Great Black-backed Gull has an

open season in Greenland between 1 September and 30 April.

It typically breeds in pairs or in loose colonies on small islands along the outer coasts.

Small numbers also breed in the fjords. No colonies are known from the Kangerluarsuk

Fjord or other parts of the study site. The nearest gull colonies are in the glacier fjord at

Akullit Nunaat north of the central part of Brede Fjord (see Section 8.5) (Boertmann

2004). Other colonies are known from the skerries and islands along the outer coast

(Boertmann 2004).

Small numbers are sometimes observed in Kangerluarsuk Fjord.

4.4.22 Lesser Black-backed gull

The Lesser Black-backed Gull (Larus fuscus) is a rather uncommon breeding bird in

Greenland, but the population is increasing, and it has recently established a breeding

population in the glacier fjord at Akullit Nunaat North of the central part of Brede Fjord

(see Section 8.5) (Boertmann 2004).



Figure 4.7 Glaucous Gulls and Great-black backed Gull rested on iceberg in South Greenland

4.4.23 Black-legged Kittiwakes

Large numbers of Black-legged Kittiwake (Rissa tridactyla) breed in Greenland but only

relatively small numbers in the South-west. The present breeding population is

estimated to 80,000 – 100,000 pairs (Boertmann 2007). The Kittiwake has declined

much in numbers in Greenland during the last decades (Boertmann 2004). The main

reason for the decline is believed to be un-sustainable hunting. Due to the large decline

the Black-legged Kittiwake is listed as “vulnerable” in the regional Greenland Red List

(Boertmann 2007). The hunting season is from 15 August to end of February.

The Kittiwake breeds in colonies on high cliffs where it often occurs in mixed colonies

with other seabird species. Very small numbers overwinter in Greenland waters and the

majority either move south along the east coast of Canada or towards the waters of

Western Europe. Outside the breeding season the Kittiwakes are largely pelagic and

remain offshore most of the time.

No colonies are known from the Kangerluarsuk Fjord or other parts of the study site.

The nearest gull colonies are in the glacier fjord at Akullit Nunaat north of the central

part of Brede Fjord (see Section 7.5) (Boertmann 2004).



Waders

4.4.24 Purple sandpiper

Purple Sandpiper (Calidris maritime) is a relatively common and widespread wader in

the low-arctic Greenland. The population is estimated to 10,000 – 20,000 pairs

(Boertmann 2007). It is protected in Greenland.

Purple sandpiper breeds in shrub heath and ferns along the fjords or near the coast

(Salomonsen 1967). Outside the breeding season it mostly occurs along the coast

where it forages in the inter-tidal zone.

Although no observations have been made of this wader during the field work in 2007-

2010, it is possible that one or two pairs breed in the study site, most likely along the

Lakseelv.

4.4.25 Ringed Plover Charadrius hiaticula

The Ringed plover (Charadrius hiaticula) breeds almost all over Greenland but is most

common in the High Arctic. The Greenland breeding population is estimated to 30,000 –

60,000 pairs (Boertmann 2007). Ringed Plover is protected in Greenland.

Ringed Plover typically breeds on sand beaches and gravel fields along the coast but

can also do so inland. It arrives to Greenland in May, and the last birds leave in early

October.

This species was not observed during the field work in 2007 to 2010. However, one or

two pairs may perhaps breed along the coast some years, in particular where Lakseelv

flows into the fjord.


5 FISH AND LARGE MARINE INVERTEBRATE

A large number of fish species occur in the Greenland fjords but generally little is known

about the species that are not utilized commercially or in connection with local

subsistence fishery (Pedersen and Kannewolf 1995).

The following account therefore focus on the key fish species that are utilized in the

fjords of South Greenland but also the Iceland scallop and Deep sea shrimp.

5.1.1 Deep sea shrimp

Deep sea shrimp (Pandalus borealis) is found throughout the North Atlantic. In

Greenland waters deep-sea shrimp occurs in waters 100 – 600 m deep, mainly offshore

on the slopes of banks but also in the deep fjords. This is commercially very important

but in recent years the populations in the fjords in south Greenland has declines much.

It is probably widespread in the deep parts of Kangerluarsuk fjord.

5.1.2 Atlantic Cod

The Atlantic cod (Gadus morhua) is common and widespread in Greenland waters north

to Qeqertarsuup Tunua. It is occurs down to about 600 m, and is found both close to the

bottom and pelagic (Bugge Jensen & Christensen 2003). During the 20th century it

fluctuated much in number and distribution, which is believed partly to be due to the fact

that it has its northernmost distribution in Greenland and consequently is sensitive to

climate changes. Atlantic Cod is common in Kangerluarsuk fjord.

5.1.3 Greenland Cod

The Greenland Cod or Uvak (Gadus ogac) occurs along the coast and fjords north to

Upernavik and is common in the fjords of the study area. It is considered inferior in the

commercial fisheries compared with the Atlantic cod, but it has some subsistence

importance (Mosbech et al. 1998). Greenland Cod is common in Kangerluarsuk fjord.

5.1.4 Spotted Wolffish

The Spotted Wolffish (Anarchchias minor) has a wide distribution along the West and

East coasts of Greenland but has decreased in abundance in recent years and the

population is estimated to be very small (Bugge Jensen & Christensen 2003). It is

mainly found in the fjords with hard bottom. The Spotted Wolffish probably occurs in all

the deep parts of Kangerluarsuk fjord.


5.1.5 Atlantic Salmon

The Atlantic salmon (Salmo salar) occurs along Greenland’s coast from August to about

November on foraging migration from the American and European continents (Bugge

Jensen & Christensen 2003). Only a single breeding river is found in Greenland (near

Nuuk). The distribution varies much between years depending mainly on the water

temperature.

In some years the Atlantic salmon is quite common in Narlunaq Skovfjord, and in

Qqqortup Ikera Julianehåbfjord (Mosbech et al. 2004), and small numbers probably also

enter Kangerluarsuk fjord.

5.1.6 Arctic Char

The Arctic char (Salvelinus alpines) is a habitat generalist like no other northern fish

found in streams, at sea and in all habitats of oligotrophic lakes throughout Greenland.

Some populations are stationary and remain in fresh water while in others the adult fish

conducts feeding movements along the coast.

Figure 5.1 Arctic char in pool in Lakselv


The distribution of Arctic char in Lakseelv and its tributary and connected lakes were

mapped in mid-June 2010. Lakseelv, Laksetværelv and other tributaries were survey

with electro-fishing equipment. Fostersø and Månesø were survey with electro-fishing

equipment and fishing rods.

Arctic char was only recorded in the lower and central part of Lakseelv (Figure 5.2)

where a large population is present. A waterfall about 5 km from the outlet of the river

(Figure 5.3) excludes further movements upstream and no Arctic char were recorded

from the upper section of the river. No fish were found in Laksetværelv. This small

stream drains Fostersø and connects with Lakseelv about 600 m from its outlet to the

fjord. A c. 75 cm high “waterfall” close to where it meets Lakseelv is probably the

reason that no Arctic char were recorded from this stream in mid-June. In winter

Laksetværelv regularly runs dry preventing a stable fish population to be established. All

the survey lakes were fishless.

Figure 5.2 Distribution of Arctic char in Lakseelv and its tributaries. Char was only recorded in the lower and middle section of Lakseelv and in a branch of this river (stream section with fish marked with red). No char were found in Fostersø or in Laksetværelv that drains Fostersø into Lakseelv

In addition to the mapping study in 2010, a survey of the char population of Lakseelv

was carried out by staff from Grønlands Fiskeri- og Miljøundersøgelser in August 1985

(Boje 1985). This team noted a waterfall, just a few hundred meters upstream from the

fjord which was believed to present a barrier for the fish and therefore effectively

separating the population into two. In June 2010, where the discharge of Lakseelv

probably was considerable higher than in August 1985, this waterfall seemed to be less

of a barrier to the fish and at least some fish were probably able to pass it and move

further upstream.


The life cycle of Arctic char in South Greenland

The Arctic char population in rivers typically consists of resident fish (non-anadromous)

and anadromous fish that migrate to the sea during summer when they have reached a

certain age. The average maximum distance travelled by Arctic char from a sea-going

population at Baffin Island was 40-50 km (Moore 1975). The seaward migration

probably stars at ice break-up in the river and the fish return in mid-summer or autumn.

The anadromous Arctic char in South Greenland start to migrate into the fjord when

they around 4 years old and c. 15 cm long (Christensen & Mortensen 1982, Boje 1985).

During the period of saltwater residence, Arctic chars frequently move into the intertidal

zone and freshwater (Moore 1975). Returning fish have been recorded in other South

Greenland rivers as early as mid-July (Christensen & Mortensen 1982) but most

seemed to move back to the river in late July and in August. This is probably also the

case in Lakseelv where small dark and spotted non- anadromous fish (parr) dominated

in mid-June as opposed to the sea-going silver Arctic char (smolts).

Figure 5.3 Waterfall about 5 km from the outlet prevent further upstream migration of char in Lakseelv

The Arctic char in South Greenland rivers typically reached sexual maturity when they

were around 5 years old that is after their first sea run (Christensen & Mortensen 1982).

The Arctic char in South Greenland spawn from late August to beginning of October. In

Narsaq elv, which is only 12 km from Lakseelv, the char mostly spawn in the main

stream on sites with gravel bottom, 30-35 cm depth and not too strong current

(Christensen & Mortensen 1982). The female dig a depression before laying the eggs

and cover the eggs with gravel by tail beats after fertilization. The eggs hatch the

following spring. In Narsaq elv by far the majority of females that spawn have spent the

summer in salt water (Christensen & Mortensen 1982).


During winter most of the Greenland’s rivers are covered by thick ice and the water flow

is very restricted. This time of the year the char spend in the deepest parts of the rivers.

In Lakseelv most char probably winter in the deep pools near the outlet of the river

(Figure 5.4). In spring the fish spread out to utilize all water-covered areas below the

rapid 5 km upstream.

Figure 5.4 Deep pool in Lakseelv a few hundred meter from the outlet in the fjord where large numbers of Arctic char spent the winter months

Food

The first weeks the fish larvae feed on yolk which they carry in a sac underneath their

belly. About a month after hatching the fry begins to feed on plankton. Later they start

to take insect larvae, in particular Chironomidae (non-biting midges), Trichoptera

(caddisflies) and Simuliidae (black flies). Insect larvae are also the main food of the

larger fish.

A study of the density of insect larvae in the Lakseelv and tributaries by Orbicon in June

2010 showed much higher densities of Chironomidae and Trichoptera just above the

waterfall that limited the char distribution in Lakseelv and low densities below the

waterfall (Table 6.2), suggesting that char predation of these insect larvae in Lakseelv is

significant. Cannibalisms probably also takes place. The char generally exhibited a very

slow growth rate while in rivers where the main foot is insect larvae. During winter they

probably eat nothing. The char that move into saltwater during summer fed on

planktonic amphipods, copepods and fish and their food intake rates and growth is

much higher than in resident char.


Population size

The August 1985 study included an attempt to assess the density and number of char in

Lakseelv. The stock of anadromous char in August was estimated to be 800 - 900 fish

(Boje 1985). No estimate of the non-anadromous population is given but the density of

fish was found to be 0.1 fish per sq. m, which is comparable to other rivers in South

Greenland (Boje 1985).

5.1.7 Capelin

The Capelin (Mallotus villosus) is widespread along Greenland’s coasts and it is an

ecological key species because it is an important food resource for larger fish, seabirds

and marine mammals. It is also exploited both commercially and for subsistence fishery.

It is believed to be common in Kangerluarsuk fjord although no exact data is available.

5.1.8 Redfish

Redfish (Sebastes spp.) are confined to deep waters offshore but also in deep fjords

where they occur at 150 – 600m. It is believed to be common in Kangerluarsuk fjord

although no exact data is available.

5.1.9 Lumpsucker

The Lumpsucker (Cyclopterus lumpus) is a common and widespread species that

spend most of the year in deep offshore waters, but in spring and early summer seek

into shallow coastal waters to spawn. It is a common species along the shores of

Kangerluarsuk fjord which has spawning grounds along most shores (see Figure 7-5).


6 FRESHWATER ECOLOGY

In the early 1970s a study of the freshwater animals was carried out in some of the

small lakes in the Study area. The freshwater fauna in Greenland comprise about 65

species of which crustaceans dominates the fauna (Bugge Jensen and Christensen

2003). This was also found to be the case in the lakes near Killavaat Alannguat where

all except one freshwater animal belonged to the crustaceans. The exception was the

beetle Colymbetes dolabratus. This is the largest beetle known in Greenland and is

unable to survive in small lakes and ponds that freeze up in winter and therefore move

to larger lakes in autumn (Bugge Jensen and Christensen 2003).

Table 6-1 Freshwater animals recorded in three lakes at Killavaat Alannguat in 1974 (from Rose-Hansen et al. 1977).

In June 2010 a brief study of the freshwater invertebrates in the main rivers and streams

in the project area was carried out. It was found that insect larvae dominated the

freshwater fauna in both Lakseelv and Laksetværelv (Table 6-2). The highest diversity

and density of insect larvae was recorded in sections of rivers with no fish predation.

The studies in the 1970s and 2010 shown that freshwater fauna in the studied rivers,

streams and lakes is relatively species poor and consist of animals that are widespread

in Greenland. The diversity and in particular density of animals recorded was (as

expected) highest in the watercourses without fish.

Arctic char was limited to the lower part of Lakseelv. A waterfall just below sample site

L1 prevents the fish from moving further upstream. No fish was recorded from

Laksetværelv which is most like caused by a waterfall close to the point where it meets

Lakseelv.

7 PROTECTED AREAS AND SPECIES OF CONSERVATION CONCERN

7.1 Threatened species

Three species – all birds - listed on the regional Greenland red list of threatened species

(Boertmann 2007) occur regularly in the Study area, see Table 7-1.

Gyrfalcon Breeding Year round Throughout Near Threatened Low

Table 7-1 Species on the regional Greenland red list of threatened species occurring in study area

White-tailed Eagle is listed “Near-threatened” because of its small total population in

Greenland. The White-tailed Eagle population in Greenland has increased in recent

decades but the total number is still small.

Gyrfalcon listed “Near Threatened” on the Greenland red list, is a widespread but low-

density breeder in South Greenland. It is on the list because of the small population in

Greenland.

Common eider is listed “Vulnerable” on the Greenland red list due to a large decline

cause but unsustainable hunting.

White-tailed eagle is definitely breeding in the Narsaq-Qaqortoq region but no breeding

sites are known from the Study area. Little is known about breeding sites for Gyrfalcon

in the region but it is unlikely to breed in the Study area. The Common eider is a winter

visitor only, whit flock occasionally feeding and resting on the fjord.

7.2 Areas protected according to international agreements

Greenland is a signature to the Ramsar Convention on projection of wetlands and their

biodiversity and has designated 11 areas to be included in the list of Wetlands of

International Importance (Ramsar Sites) (Egevang & Boertmann 2001). None of the

Greenland Ramsar Sites are situated in the proximity of the study area (Figure 7.1).


7.3 Areas protected according to national legislation

A number of nature reserves and a single national park (the Northeast Greenland

National Park) have been designated according to the Greenland nature protect law.

This includes a number of sites protected according to national and local regulations. All

protected areas in south-west Greenland are shown in Figure 7.1. None of the

protected areas are located in or close to the study area.

Figure 7.1 Protected areas in South Greenland. Areas marked with red are protected according to national legislation (but none are designated in South Greenland). Areas marked with blue are protected according to local legislation. Areas marked with yellow are Ramsar Sites. Areas marked with green are Important Bird Area (IBA) – but none are found in South Greenland (from Boertmann 2005)

7.4 Areas of conservation concern identified by NGOs

The global Non-government conservation organization BirdLife International has

identified 55 “Important Bird Areas” – IBA’s for Greenland (BirdLife International 2012).


The criteria for an IBA is that the site either holds significant numbers of one or more

globally threatened (bird) species, is one of a set of sites that together hold a suite of

restricted-range species or biome-restricted species or has exceptionally large numbers

of migratory or congregatory species. None of the proposed IBAs for Greenland are

situated in or close to the study area.

7.5 Sea bird colonies near the project area

Several sea birds colonies are found along the coasts of South Greenland. Figure 7.2

shows the location of sea bird colonies with more than 500 breeding birds. None of

these colonies are situated close to the study area.

Figure 7.2 Distribution and size of larger sea bird colonies (> 500 individuals) in South Greenland (from Mosbech et al. 2004)

A number of small sea bird colonies (less than 500 breeding birds) are found in the

Ikersuaq/Bredeford fjord system close to Narsaq (Figure 7.3). A sea bird colony is

indicated along the coast of Qaqortukulooq bay close to Hvalsø church – that is near

the study area. A survey of the coastline in 2010 found no sign of breeding sea birds in

this area. It is unknown if sea birds previously did breed along this coast or if it is an

error.

7.6 Areas important to wintering sea birds

The Julianehåb Bay has been identified as a hot spot for wintering area for sea birds.

The northern part is in particular important to Common eider, Harlequin duck and

Brünnich’s Guillemot while the southern part is important to common eider (Boertmann

et al. 2004) see Figure 7.4. These areas are all outside the Study area. Common eiders

also regularly overwinter in fjords in South Greenland. Here flocks of several hundred

birds regularly are observed (pers. obs.). It is unknown to what extent Common eiders

winter in Kangerluarsuk Fjord but it is likely that at least small number sometimes

moves into the fjord to feed on mussels at the sea bottom.


Figure 7.4 Important areas for wintering sea birds off South Greenland (dark areas). The northern part (area 6) is particular important to Common eider, Harlequin duck and Brünnich’s Guillemot while the southern part (area 7) is mainly important to Common eider. From Boertmann et al. 2004

7.7 Environmental importance and resource use of shorelines of the study area

The report “Environmental Oil Spill Sensitivity Atlas for the West Greenland Coastal

Zone” published by NERI (Mosbech et al. 2004) includes, among other things, an

assessment of the importance of West Greenland shore lines from an ecological and

human use perspective. Although the study is part of the preparation for exploratory

oil/gas drilling offshore south-west Greenland it offers useful information on the

occurrence of fish and sea birds along the shores of the study area.

The following account is based on Mosbech et al. (2004). This study was prepared as

part of the preparation for exploratory oil/gas drilling offshore southwest Greenland but

offers very useful information on the occurrence of fish, sea birds, and sea mammals

and their local use. In this study the shoreline is divided into sections (see Figure 7.5).

The environmental description and resource use of the shoreline sections within the

study area are presented below.

Shoreline section 60_80:

Lumpsucker spawning takes place along the coast. The shoreline is subject to fishery

for Lumpsucker (important), Atlantic cod and Greenland halibut with important fishing

grounds along almost all coasts. Hunting for Fin and Minke whales and seals also takes

place.



for Capelin, Lumpsucker (important), Atlantic cod with important fishing grounds along

almost all coasts and fishery for Arctic Char in one river outlet. Hunting for Fin and

Minke whales and seals also takes place.




for Iceland Scallop, Lumpsucker (important), wolffish, Salmon, Atlantic cod with fishing

grounds along all coasts, and to fishery for Arctic char in two river outlets (both

important). Hunting for Fin and Minke whales, Harbour porpoises and seals also takes

place.



for Lumpsucker (important), wolffish, Atlantic cod and Salmon with important fishing

grounds along almost all coasts. Hunting for Fin and Minke whales, Harbour porpoises

and seals also takes place.



for Icelandic Scallop, Snow crap (important), Lumpsucker (important), wolffish, Salmon,

and Atlantic cod with important fishing grounds along all coasts. Hunting for Fin and

Minke whales, seals, Harbour porpoises and guillemots also takes place.

Shoreline section 60_93 (Kangerluarsuk Fjord)


for Capelin, Lumpsucker (important), wolffish, Atlantic Cod (pound net), Salmon with

important fishing grounds along all coasts and to fishery for Arctic Char at the Lakseelv

river outlet. Hunting for seal takes place.

Shoreline section 60_94 (Narlunaq/Skovfjord)


for Capelin, Lumpsucker, Snow crab, wolffish, Arctic char at coast, Atlantic cod (pound

net), Greenland halibut, redfish and Salmon with important fishing grounds along almost

all coasts. Hunting for seals and guillemots takes place.

The area marked S 97 on Figure 7 has special importance because of the famous

archaeological site Hvalsø. This Norse church ruin is an important tourist attraction.

However, the area is also important for fisheries for Capelin and Lumpsucker.


Figure 7.5 Shoreline map of the study area and surroundings with indications of sensitivity to oil spill shown with different colours (from Mosbech et al. 2004). Small blues squares show archaeological sites. A “person” indicates places with important resources for human use. “LU” is a site important to lumpsucker. “AR” is a river/lake with Arctic Char. A description of key environmental issues and resource use for the different shoreline sections in the study area is given in section 8.7.
