A Major Threat to Grauer’s Gorillas
Snaring is one of the main threats to wildlife within Kahuzi-Biega National Park in eastern Democratic Republic of the Congo (DRC). Poachers use cables or wires to make traps for small antelopes, wild pigs, or other game. Unfortunately, gorillas can also get caught in these wire traps. Some, like Meteo, shown below, have lost limbs while others have died. Meteo, who was trapped in a snare five years ago and lost his left hand, is a member of the Chimanuka Group.
Independent photojournalist Allison Shelley captured striking images underscoring the importance of the anti-poaching work of our Congolese partner Primate Expertise (PEx), led by founder and executive director Dr. Augustin Basabose.

Snare Removal and Anti-Poaching Patrols
PEx trains and equips park rangers to conduct regular anti-poaching and snare removal patrols. Patrols also collect information subsequently used by Dr. Basabose to assess how snare-induced injuries impact ape behavior.
PEx works closely with Congolese Institute for the Conservation of Nature (ICCN) to implement a snare-removal program within the park’s upland sector, mitigating a key threat to gorillas and other wildlife.

Ecological Monitoring and Research Reduce Snaring
Camera traps can be used to help find animals injured by snares, assess seasonal population movement, and identify wildlife sharing the same habitat as gorillas. Together with PEx, we have established an effective biomonitoring system using camera traps and wildlife surveys to document Grauer’s gorilla population, ecology, and behaviors.
These field observations are analyzed and translated into timely management response. For example, patrols can be shifted to areas experiencing poaching pressures in real time. The sustained presence of the PEx research team in Kahuzi-Biega also deters poachers and strengthens protection of Grauer’s gorilla and other wildlife.

Expanding Programs to Surrounding Area
PEx expanded its surveillance program by placing 10 additional camera traps at the park’s boundary to document crop raiding events and identify animals that cross into community farmland. The aim is to reduce conflict between farmers and park authorities.
In recent years, farmland has extended to the edge of the park where there is increasing contact between foraging wildlife and farmers. We have done similar work in Cambodia with Asian elephants and farmers living on the edge of Prey Lang forest in order to reduce human-wildlife conflict.
