Site description
This site is a highly indented mountainous massif, composed of migmatite, quartzite and granite, and with steep slopes. Its north-eastern part, which is steeper, is part of the crystalline edge of the Andapa basin. Annual rainfall can exceed 3,000 mm at the higher altitudes. The reserve is the most important watershed for the rivers flowing to the north and the south of the Andapa basin to join the rivers flowing to the east. The main rivers are the Andramonta in the north, the Marolakana in the centre, and the Ankaibe and Manandriana in the south-east. Three types of vegetation can be found: low-altitude, dense, humid evergreen forest (up to 900 m); mid-altitude, dense, humid evergreen forest (900–1,100 m); and dense montane forest (above 1,100 m). Notable forest trees include Dalbergia, Diospyros, Weinmannia and Eugenia.

Key biodiversity
See Box and Tables 2 and 3 for key species. The site holds most of the species that are characteristic of the eastern forest.
