Sarambwe Wildlife Reserve, located in the Democratic Republic of Congo (DRC), shares a border with Bwindi Impenetrable National Park (BINP), creating a pathway for various wildlife, particularly mountain gorillas. The reserve spans an area of 9 square kilometers.

Gorilla presence was consistently noted throughout the year, with signs observed during all 9 months. In the period from January to April 2021, an estimated 18-23 gorillas were recorded visiting the reserve. From May to July, the reserve hosted 20 gorillas, belonging to three groups comprising 3, 6, and 10 individuals, along with a solitary individual. These same three groups and one lone gorilla were again observed in August and September.

Elephants were spotted in the reserve during five months: January, May, June, July, and September 2021. Their numbers fluctuated between 1 and 3 individuals.

The reserve’s most prominent primate species include red-tailed monkeys, black-and-white colobus monkeys, baboons, chimpanzees, and blue monkeys. These species were consistently sighted throughout the reserve. Red-tailed monkeys were the most frequently observed, encountered between 12 and 25 times per month. They form various groups, ranging from 6 to 36 individuals. Baboons were seen 9-16 times a month, often in groups of 3-36 individuals. Black-and-white colobus monkeys were encountered 6 to 14 times a month, typically in groups of 4-44 individuals. Chimpanzees were observed in up to 4 groups, each containing 6, 6, 8, and 12 individuals, respectively.

Additionally, the reserve is home to other notable species like bush pigs and duikers.

These observations highlight the significance of the wildlife reserve and its role in conserving these diverse and important species.
