Site description
Tsaratanana, located south of Ambanja, is the highest mountain range in Madagascar, with the peak of Maromokotro rising to 2,876 m. It is of volcanic origin, being composed of granite and migmatite. The headwaters of the Ramena, Sambirano and Mahavavy rivers lie within the reserve. Mid-altitude, dense, humid evergreen forest, characterized by an abundance of trees 10–12 m high, lianas and palms, covers the area up to 2,000 m. Dense bamboo forest, forming a belt, characterizes the area located between 2,000 and 2,200 m. Sclerophyllous montane forest is found between 2,200 and 2,600 m and grassy savanna occurs above 2,600 m (of human origin, having replaced the original montane bushland following repeated burning and livestock-grazing).

Key biodiversity
See Box and Tables 2 and 3 for key species. Ninety-four species are known from the site, of which 56 are endemic. Tyto soumagnei was found at an altitude of 2,000 m, the highest known for this species. This is also the northern limit known for Eutriorchis astur. Many species occur at higher altitudes here than elsewhere in their ranges. The subspecies Saxicola torquata tsaratananensis is limited to this site.
