Phase 2

Between 95 and99% of thesespecies areendemic to theLake / Naturallynot foundanywhere else.

Lake Niassa

Our Key Biodiversity Area (KBA) Home to an estimated 1000 freshwater fish species

≈ 15% of the world’s total. 104 of thesespecies areconsideredthreatened bythe InternationalUnion for theConservation ofNature (IUCN).

(See our species cards for information on some of the threatened species that the Manda Wilderness Biodiversity Project aims to protect)

…As well as agreat diversityof smallmammals,reptiles,amphibians,insects andflora.

The Lake´s Hinterland

Home toAfrica´s flagshipspecies such asthe buffalo,elephant,leopard andsable antelope,to name a few…

Recognized for its local bird populations…

And its role as a staging post for migratory birds flying between Africa and Europe.

The Lake´s PeopleLake Niassa has been vital to thesustenance of the surroundingpopulations' livelihoods through activitiessuch as fishing, agriculture, animal rearing,hunting, trade and handicrafts.

Despite national and international efforts,the lake continues to face severe threats,primarily due to overharvesting andsiltation.

On one hand, because fresh and dried fishfrom the lake provides the main source ofdietary protein for the human populations.

On the other, because although the civilwar in Mozambique did leave the alreadyremote region of the country sparselypopulated, human populations have beenreturning in the past 20 years increasingdeforestation and agricultural expansion.

Our Objective:

Partner with the Lake´s people

Understand and improve their livelihood activities

Habitat and Ecology: A lacustrine species, living in the pelagic zone of the lake.Juveniles remain close inshore and near the river mouths. The adults arepiscivourous, feeding on small pelagic fishes. Young fish feed on plankton, insectsand other small organic matter. It migrates up rivers from the lake to spawn duringthe rainy season.

Spawning mainly takes place at night andrequires well-oxygenated flowing waters andsilt free gravel. Spawning takes place in veryshallow water and occurs over an extendedperiod during and after the rains.

Opsaridium microlepis Lake salmon (continued)

enKingdom Phylum Class Order Family

ANIMALIA CHORDATA ACTINOPTERYGII CYPRINIFORMES CYPRINIDAE

Species Authority: (Günther, 1864)

Major Threat(s): Over-fishing: extremely high mortalities of adults during spawning runs due tototal blocking of rivers with gill nets and weirs as well as drifting gillnets. This prevents upstreammigration in low rainfall years. Fish poisoning is widely practised although illegal. Deterioration ofspawning grounds due to siltation from soil erosion (bad land practice as well as deforestationalong rivers). Water abstraction for irrigation purposes during dry season hampers downstreammovement of young fish.

Conservation Actions: One major river where this species breeds is the Bua river, which runsthrough the Nkhota Kota game reserve (Central Malawi). This is the only river where the spawninggrounds are protected (as the surrounding woodlands are protected from deforestation). Theheadwaters of the North Rukuru river are also protected within the Nyika National Park — there ishowever increasing land clearance between the park and the spawning grounds. The Linthipe river,a major spawning river, is unprotected, receiving untreated effluent from Lilongwe. The status of'mpasa' rivers in Tanzania and Mozambique is Unknown.

Oreochromis karongae (coninued)

enKingdom Phylum Class Order Family

ANIMALIA CHORDATA ACTINOPTERYGII PERCIFORMES CICHLIDAE

Species Authority: (Trewavas, 1941)

Habitat and Ecology: This is one of the three 'Chambo' species endemic to Lake Malawi. Likeother species of the subgenus Nyasalapia, males of O. karongae develop long branchedgenital 'tassels' that serve as egg dummies. Territorial male O. karongae are jet black, with awhite dorsal fin margin.

O. karongae can be seen in loose shoals in many areas of the lake. They feed by rasping thesurfaces of rocks and weeds and by sifting sediment and also feeding in the water column.They eat mainly algae, detritus and zooplankton. Max. size: 37 cm TL (Total Length).

The breeding season runs from July to March, peaking around September and again inFebruary. In Lake Malombe there is just a single peak around July to October. Like otherOreochromis they are maternal mouthbrooders. Males dig large spawning platforms inwaters ranging from the shallows down to depths of at least 28 m. Like other chambo, theyconstruct a slightly raised bowl-shaped central spawning cone inside the larger pit.

Panthera pardus LeopardNT

Kingdom Phylum Class Order Family

ANIMALIA CHORDATA MAMMALIA CARNIVORA FELIDAE

Species Authority: (Linnaeus, 1758)

Habitat and Ecology: The leopard has the widest habitattolerance of any Old World felid, ranging from rainforest todesert.

In Africa, they are most successful in woodland, grasslandsavanna and forest but also occur widely in mountain habitats,coastal scrub, swampy areas, shrubland, semi-desert and desert.They range from sea level to as much as 4,600 m on Mt Kenya(Hunter et al.).

Leopards have extremely catholic diets including more than 90 species in sub-Saharan Africa,ranging from arthropods to large antelope. Densities vary with habitat, prey availability, and degreeof threat, from fewer than one per 100 km² to over 30 per 100 km², with highest densities obtainedin protected East and southern African mesic woodland savannas (Hunter et al.).

Panthera pardus Leopard (continued)NT

Kingdom Phylum Class Order Family

ANIMALIA CHORDATA MAMMALIA CARNIVORA FELIDAE

Species Authority: (Linnaeus, 1758)

Major Threat(s): Throughout Africa, the major threats to Leopard are habitatconversion and intense persecution, especially in retribution for real andperceived livestock loss (Ray et al.2005. Nonetheless, Leopard are somewhattolerant of habitat conversion, and may persist close to large humanpopulations provided they have suitable cover and prey (Hunter et al. in press).

Leopard come into conflict with people across their range. A rapidly increasingthreat to Leopards is the poisoning of carcasses targeting carnivores, either asa means of predator control or incidentally.

The impact of trophy hunting on populations is unclear, but may have impacts at the demographic and populationlevel, especially when females are shot. In Tanzania, which allows only males to be hunted, females comprised 28.6%of 77 trophies shot between 1995 and 1998 (Spong et al. 2000).

Skins and canines are still widely traded domestically in some central and West African countries where parts areused in traditional rituals and sold openly in villages and cities (Hunter et al.). Djibouti is an important conduit forLeopard skins from East Africa that are bought mainly by French military personnel and carried illegally to Europe.

Lycaon pictus African wild dogen

Kingdom Phylum Class Order Family

ANIMALIA CHORDATA MAMMALIA CARNIVORA CANIDAE

Species Authority: (Temminck, 1820)

Habitat and Ecology: African Wild Dogs are generalist predators, occupying a range ofhabitats including short-grass plains, semi-desert, bushy savannas and upland forest.While early studies in the Serengeti National Park, Tanzania, led to a belief that AfricanWild Dogs were primarily an open plains species, more recent data indicate that theyreach their highest densities in thicker bush (e.g., Selous Game Reserve, Tanzania;Mana Pools National Park, Zimbabwe; and northern Botswana). Several relictpopulations occupy dense upland forest (e.g., Harenna Forest, Ethiopia; Malcolm andSillero-Zubiri 2001). African Wild Dogs have been recorded in desert (Lhotse 1946)(although most desert populations are now extirpated), but not in lowland forest. Itappears that their current distribution is limited primarily by human activities and theavailability of prey, rather than by the loss of a specific habitat type.

African Wild Dogs mostly hunt medium-sized antelope. Whereas they weigh 20–30 kg, their prey average around 50 kg, and may beas large as 200 kg. In most areas their principal prey are Impala (Aepyceros melampus), Greater Kudu (Tragelaphus strepsiceros),Thomson's Gazelle (Eudorcas thomsonii) and Common Wildebeest (Connochaetes taurinus). They will give chase of larger species,such as Common Eland (Tragelaphus oryx) and African Buffalo (Syncerus caffer), but rarely kill such prey. Small antelope, such as Dik-dik (Madoqua spp.), Steenbok (Raphicerus campestris) and Duiker (tribe Cephalophini) are important in some areas, and warthogs(Phacochoerus spp.) are also taken in some populations. African Wild Dogs also take very small prey such as hares, lizards and eveneggs, but these make a very small contribution to their diet.

Kingdom Phylum Class Order Family

ANIMALIA CHORDATA MAMMALIA CARNIVORA CANIDAE

Species Authority: (Temminck, 1820)

Major Threat(s): The principal threat to African Wild Dogs is habitat fragmentation, which increases their contact with people and domesticanimals, resulting in human-wildlife conflict and transmission of infectious disease. The important role played by human-induced mortalityhas two long-term implications. First, it makes it likely that, outside protected areas, African Wild Dogs may be unable to coexist withincreasing human populations unless land use plans and other conservation actions are implemented. Second, African Wild Dog rangingbehaviour leads to a very substantial "edge effect", even in large reserves. Simple geometry dictates that a reserve of 5,000 km² contains nopoint more than 40 km from its borders – a distance well within the range of distances travelled by a pack of African Wild Dogs in their usualranging behaviour. Thus, from an African Wild Dog's perspective, a reserve of this size (fairly large by most standards) would be all edge. Ashuman populations rise around reserve borders, the risks to African Wild Dogs venturing outside are also likely to increase. Under theseconditions, only the very largest unfenced reserves will be able to provide any level of protection for African Wild Dogs. In South Africa,“predator proof” fencing around small reserves has proved reasonably effective at keeping dogs confined to the reserve, but such fencing isnot 100% effective (Davies-Mostert et al. 2009) and is unlikely to be long-term beneficial for wildlife communities.

Even in large, well-protected reserves, or in stable populations remaining largely independent of protected areas (as in northern Botswana),African Wild Dogs live at low population densities. Predation by Lions, and perhaps competition with Spotted Hyaenas, contribute to keepingAfrican Wild Dog numbers below the level that their prey base could support. Such low population density brings its own problems. Suchsmall populations are vulnerable to extinction. "Catastrophic" events such as outbreaks of epidemic disease may drive them to extinctionwhen larger populations have a greater probability of recovery – such an event seems to have led to the local extinction of the small AfricanWild Dog population in the Serengeti ecosystem on the Kenya-Tanzania border. Problems of small population size will be exacerbated if, asseems likely, small populations occur in small reserves or habitat patches. As discussed above, animals inhabiting such areas suffer a strong"edge effect". Thus, small populations might be expected to suffer disproportionately high mortality as a result of their contact with humansand human activity.

Nectarinia neergardiKingdom Phylum Class Order Family

ANIMALIA CHORDATA AVES PASSERIFORMES NECTARINIIDAE

Species Authority: (Grant, 1908)

NT

Habitat and Ecology: This species is a sometimes common, but nomadic,species of woodland, especially dry, dense forest on sandy soil. It alsoinhabits coastal scrubland and has been recorded in isolated trees inclearings and villages (Cheke and Mann 2001).

It is found only at low elevations and apparently avoids fragmented coastalforest (Clancey 1985). It consumes nectar, small insects and spiders (Chekeand Mann 2001). The nest, in which a clutch-size of two has beenrecorded, is suspended from a tree and made of cream-coloured fibrousmaterial, feathers and down, and camouflaged with insect larvae andother debris. Observations suggest that breeding activity occurs inSeptember-January and possibly July (Cheke and Mann 2001).

Major Threat(s): In southern Mozambique, the species's coastal forest habitat is highly threatened,particularly by commercial logging and afforestation with non-native tree species (Parker 1999).
