ARSG meeting, definitions. In an effort to focus international attention on those populations considered to be the most important for the survival of the six recognised subspecies of white and black rhinos in Africa, a rating exercise was undertaken.
It was agreed that the most relevant parameters an which to judge the conservation value of populations were population size, the significance of the population in conserving the relevant subspecies, and the likelihood of protection measures being effective (as indicated by recent population trend). Two importance categories were recognised, namely 'Key' [critically important] and 'Important' [extremely valuable], and the reserves listed accordingly as shown in Table 2.
Table 2. Key rhino populations
A1. Population increasing or stable, n>100 or n>50% of subspecies
Black rhino: Cameroon, Damaraland, Hluhluwe-Umfolozi, Kruger
White rhino: Gramaba, Hluhluwe, Itala, Kruger, Mkuzi, Pilanesburg, Sabi Sand (P)
A2. Population increasing or stable, n-51-100 or n=26-50% of subspecies
Black rhino: Itala, Midlands (Private), Mkuzi, nairobi, Selous, Solio (private)
White rhino: Loskop, Manyaleti, Ndumo, Solio (private), Timbavati (private)
A3. Population decereasing & n>50 or n>25% of subspecies, OR n>100
Black rhino: Hwange
White rhino: Hwange
Important rhino populations
B1. Population increasing or stable & n=20-50
Black rhino: Aberdares, Addo, Bubiana (P), Lake Nakuru, Lonely Mine (P), Luangwa South, Masai Mara, Ndumo, Pilanesberg, Save valley (P), Waterberg Plataeu
White rhino: Borakalalo, Botsalano, Klaserie (P), Madikwe, Manyaleti, Matobo, Midlands (P), Mkhaya (P), Tembe, Tsolwane, Waterberg Plateau, Weenen
