Endangered Madagascar lemur nears extinction from forest destruction

By Josia Razafindramanana, special to mongabay.com

A small group of crowned sifaka lemurs Propithecus coronatus have been located in the corridor d’Amboloando-Dabolava, Miandrivazo district-Madagascar, but are immediately threatened with local extinction. The small, fragmented, and isolated forest shelters a group of only six adults and one baby. Interviews with local people revealed that once several groups of the species resided in the corridor, and even last year, about 20 individuals were still found there. However, within one year, the population dropped from 20 to 6 individuals. Hunting of the crowned sifaka is taboo in the area, but other activities, such as mining, charcoal production and logging have devastated the corridor. Currently 70 percent of the forest is degraded. If the crowned sifaka individuals in this area are to survive, emergency conservation action is required. Illegal exploitation of the trees in the corridor must be stopped in order to save the ecosystem and preserve the water sources along the corridor. However, another option is to implement a translocation of the few remaining crowned sifakas to nearby forests or even to zoos. Currently, logging activity is the main threat, since the forest contains many precious trees highly valuable for trade. Large trees over 20 meters in height have disappeared in a very short time, and they continue to be cut down to clear areas for charcoal production or to be burned to extract gold from rocks. On average one tree per day is cut, resulting in a dramatic decline in forest cover. The livelihood of the local people is gold mining. Artisanal mining occurs all over the corridor, thus forest regeneration is very low due to this exploitation by people from nearby Miandrivazo and Antananarivo. …
