The Andasibe Forest where I am now hosts an incredible number of frogs. In Madagascar the endemic frogs and treefrogs are more than 420. Every time we pass in the forests of the large island we find new species. We have to struggle to describe them all: the problem is that most of them are so microendemic that the disappearance of one small forest fragment due to human activities can make disappear a distinct species, at a much accelerated rate. In Andasibe, Perinet, Analamazaotra, Maromizaha, Ambavaniasy and Vohimana the species number is much higher than 100. Their conservation is an imperative.
