The population of Uganda's mountain gorillas has grown to 400, up from 302 in 2006, according to a census conducted last year, bringing the total number of mountain gorillas in Africa to 880 and giving hope to conservationists trying to save the critically endangered species.
Uganda is now home to nearly half of the world's mountain gorillas remaining in the wild, a source of confidence for a country that has come to depend heavily on the popular apes for substantial tourism revenue. The rest of the surviving mountain gorillas — the species Gorilla beringei beringei — are in Congo and Rwanda.
