Kalinzu Central Forest Reserve
East Africa > Uganda > Kalinzu Central Forest Reserve
Summary
- Eastern chimpanzees (Pan troglodytes schweinfurthii) are present in Kalinzu Central Forest Reserve.
- It has been estimated that 230 individuals from four communities occur in the site.
- The chimpanzee population trend is unknown.
- The site has a total size of 147 km².
- Key threats to chimpanzees are snares and live traps targeting smaller animals.
- Conservation activities have focused on ecotourism and the removal of snares in the forest.
Site characteristics
The site is located in the Albertine Rift in western Uganda. Kalinzu Forest Reserve has over 414 tree species including shrubs, several primates, including chimpanzees, blue monkeys, vervet monkeys, baboons, black and white colobus monkeys, more than 380 bird species, as well as hundreds of moth and butterfly species (Uganda Parks n.d.). The reserve is adjacent to the Queen Elizabeth National Park and the Maramagambo Forest. It lies at an average altitude of 1,400 m above sea level (Uganda Parks n.d.).
