Western lowland gorillas are highly intelligent, socially complex great apes whose captive welfare depends on appropriate group dynamics, cognitive enrichment, and positive keeper relationships. They are also among the most critically endangered primates.
Gorilla welfare in captivity is shaped by social structure, diet, and cognitive engagement. The social complexity of gorilla groups means that introductions, transfers, and group changes require exceptional care — social disruption causes severe stress in both silverbacks and adult females. The cardiovascular disease epidemic in captive gorillas — historically driven by high-sugar, low-fibre diets — has been substantially reduced through browse-based dietary management, demonstrating how welfare science translates directly into health outcomes. Cognitive enrichment that challenges gorilla intelligence — puzzle feeders, novel objects, keeper relationship building — prevents the boredom-related stereotypies that are welfare indicators in cognitively sophisticated species.
