Zone Mont Ntringui
Originally, Anjouan was covered with forests. There are currently only a few remains located on the steep and inaccessible slopes. The residual forests of Anjouan, including those of Mount Ntringui, are of great interest in terms of biodiversity since they are home to endemic and endangered species. There is a great wealth of orchids and selaginella and the presence of tree ferns and Philippia tree heather. In particular, there are two species of giant bats endemic to the Comoros: Livingstone's fruit bat, Pteropus livingstonii, and Pteropus seychellensis var. comorensis, the Comoros Founingo or Blue Pigeon (Alectroenas sganzini), several species of birds, fish and reptiles. The mongoz lemur (Eulemur mongoz) although rare in Madagascar, is a widespread species in Anjouan. Lake Dzialandze, in the center of Anjouan and at the top of the mountain ridges, is the largest lake on the island. The lake and its surroundings are a habitat for grebes, freshwater fish and several other forest species. Until now, these sites have been preserved due to their reduced accessibility. They are currently under pressure from deforestation and the expansion of agricultural and grazing land, lack of management, the search for valuable timber and the introduction of exotic species. So far, these sites have been preserved due to their reduced accessibility. They are currently under pressure from deforestation and expansion of agricultural and grazing land, lack of management, the search for precious woods and the introduction of exotic species.
