An ecological survey on chimpanzees was carried out in the Kalinzu Forest, Republic of Uganda, between October 1992 and March 1993. The research consisted of direct observation of chimpanzees and a population census based on nest counts from line transects. The population census provided the estimate density of 2.5 chimpanzees/km2. The Kalinzu Forest consists of two types of vegetation: Parinari dominant primary forest and Musanga dominant secondary forest. The estimate density of chimpanzees was higher in Musanga dominant forest than in Parinari dominant forest. The presence of two types of vegetation in the habitat was thought to allow the high density of chimpanzees in the Kalinzu Forest.
