     Located within the Kibale Forest National Park of Uganda, the Ngogo Research Area has a rich history of primate and tropical ecology research. From its inception in 1975, the site has enjoyed a long history of protection and few disturbances. Research at Ngogo has provided valuable data on primate biology, behavior, and ecology. While most famous today for its chimpanzee population, studies of both the forest and the multiple primate species there have been conducted by scientists from around the world. This symposium reviews an array of features of the Ngogo site, examining how the ecology of this site interacts with its primate community. We will review the history of the site, examining human occupation and subsequent succession in relation to primate food availability. The interaction of Ngogo forest species, canopy architecture, and primate positional behavior and support use is assessed in relation to logging and conservation. Using data on red colobus at Ngogo, the ecological constraints model of group size and travel distance is evaluated, and redtail habitat use in relation to group size and feeding ecology will be reviewed. The chimpanzees of Ngogo have the largest recorded group size, and their impact on red colobus density is discussed. The feeding ecology of this unique chimp community is also analyzed to determine how the Ngogo forest supports such a large group.
