Primate trekking tourism including mountain gorilla and bonobo watching can support conservation when welfare guidelines are followed; close contact and photo props cause significant harm.
Primate tourism spans the full welfare spectrum from genuinely conservation-supporting, welfare-protective gorilla trekking to severely harmful photo prop and direct contact experiences. Mountain gorilla trekking, when conducted according to strict protocols, has funded population recovery from under 300 to over 1000 individuals while generating revenue that makes wild gorillas economically valuable to local communities. Photo prop tourism typically involves infant animals removed from social groups, kept in inappropriate conditions, and habituated to humans in ways that prevent return to wild social groups. Consumer choices between these experiences have direct welfare consequences.
