Population and Habitat Viability Assessment: Bearded Vulture (Gypaetus barbatus)<br />
________________________________________________<br />
9. Protection status<br />
Bearded Vultures are not threatened globally (BirdLife International 2000), and are estimated<br />
to have a global range of 10 6 to 10 7 km 2 with a population of 10 4 to 10 5 individuals. It is<br />
however thought that the population is declining worldwide but not at a sufficiently fast rate to<br />
rate its status as anything higher than ‘Least Concern’ (BirdLife International 2004). However,<br />
in southern Africa it is classified as Endangered (Anderson 2000) with about 38% of<br />
population lost in recent times.<br />
Representation in conserved areas: there are between 12 and 19 pairs and between 29<br />
and 49 individuals in six Important Bird Areas (IBAs) in Lesotho (Appendix 1; Barnes 1998a),<br />
however, ALL Bearded Vultures breed in Lesotho OUTSIDE of protected areas. Considering<br />
that Lesotho is the heartland of this species (with about 60% of local deme) this is a serious<br />
issue. In South Africa there are Bearded Vultures in IBAs in KwaZulu-Natal: six IBAs with 30<br />
pairs and 61 to 102 individuals (Appendix 1; Johnson, Barnes and Taylor 1998) and in the<br />
Free State two to five individuals, but no breeding pairs in three IBAs (Appendix 1; Barnes,<br />
Colahan, Nuttall and Taylor 1998). Of the 15 IBAs in which Bearded Vultures have been<br />
recorded only six have had any breeding observed – a bleak picture (Appendix 1; Barnes<br />
1998b). Even if these figures are reasonable and if the total number of breeding pairs is about<br />
204 and the total number of individuals is about 630, see above, then this means that only<br />
21% to 24% of breeding pairs and only 15% to 25% of all individuals are within IBAs. In fact,<br />
this conveys a false sense of protection because Bearded Vultures wander far and wide in<br />
their daily foraging and so could spend most of their day outside protected areas.<br />
10. Habitat requirements<br />
In southern Africa, currently restricted to Alpine, Sour and Mixed Grasslands on rugged<br />
mountains and escarpments, all >1 500 m, though this was not the case in the past (Brown<br />
1997a). They forage along ridges and valleys in protected areas but range out over communal<br />
and commercial lands with adult birds more frequently avoiding human habitation, while birds<br />
of all ages can visit vulture restaurants (Brown 1997a).<br />
11. Threats<br />
Each of the major causes of decline are presented and evaluated in terms of their likely impact<br />
(Anderson 2000).<br />
