This is the first assessment of the status of cheetahs, Acinonyx jubatus, in Tanzania since 1965. It completes a series of recent studies in Kenya, Uganda, and Malawi to provide an overall understanding of the species' status in East Africa. Interviews with 370 informants yielded 1050 cheetah sightings. Eighty nine percent of all sightings were made in 1990-1994, and 39% of all sightings occurred in protected areas. All-adult groups contained 1.92 +/- 0.04 S.D. individuals; the average number of dependent cubs was 2.63 +/- 0.08 S.D.; and the cub-to-adult ratio was 0.34. Since the 1960s, the distribution has remained stable overall with possible reductions in central Tanzania. No definite population trends were detected. With an estimated 569-1007 cheetahs, Tanzania emerges as a sanctuary for the species worldwide. However rangelands, which may hold half of Tanzania's cheetahs, are undergoing rapid degradation. This precarious situation calls for the establishment of a nationwide monitoring program. Distribution map and population sizes from this study could serve as a baseline for monitoring the species' status. (C) 2002 Elsevier Science Ltd. All rights reserved.
