We report the current species distribution and population estimate for the chacma baboon (Papio ursinus) in KwaZulu-Natal Province (KZN), South Africa, based on an analysis of estimated area of occupancy and estimated home range size. This estimate suggests a total population size of approximately 11,000 individuals for KZN. Much of the province is uninhabited, with a density in occupied areas of approximately 1.8 animals per km(2). The current population size may be more than an order of magnitude smaller than historical population size. Chacma baboons now exhibit a highly fragmented and discontinuous distribution in KZN, with 58% of the population residing within protected areas, and more than half of these troops reside in areas >1,500 m above average sea level. The small population and highly fragmented distribution of chacma baboons in KZN, combined with rapidly increasing human population size and transformation of natural habitat, suggest this species requires greater conservation attention.
基于对估计的栖息地面积和估计的家域大小的分析，我们报告了南非夸祖鲁-纳塔尔省（KZN）的东非狒狒（Papio ursinus）的当前物种分布和种群估计。这一估计表明，KZN的东非狒狒种群总数约为11,000只。该省大部分地区无人居住，在有狒狒居住的地区，密度约为每平方公里1.8只动物。当前的种群数量可能比历史种群数量小一个数量级以上。如今，东非狒狒在KZN呈现出高度碎片化和不连续的分布，58%的种群栖息在保护区内，其中一半以上的群体栖息在平均海拔1500米以上的地区。KZN东非狒狒种群数量少且分布高度碎片化，再加上人类人口的迅速增长和自然栖息地的转变，表明该物种需要更多的保护关注。
