Western lowland gorillas are critically endangered great apes. Their welfare in zoos requires sophisticated management of their complex social structures while contributing to conservation.
Gorilla welfare in zoos depends on replicating the social complexity of wild troops while managing the unique challenges of maintaining a single-male harem structure in captivity. Silverbacks require stable relationships with their females; disrupting group composition causes significant social stress. Enclosures must provide indoor and outdoor spaces with climbing structures, foraging opportunities, and privacy for subordinate individuals. Behavioral monitoring for stereotypic behavior, food competition, and aggression helps identify social problems early. Zoo gorilla populations contribute to conservation through the Gorilla SSP, field conservation funding, and public education about the bushmeat trade and Ebola threats to wild populations.
