The climate
The annual pluviometry is about 1500 – 2000 mm , eastern slopes being more watered than western slopes. From april –mai , the dry season lasts at least 3-4 month . The mountain heights undergo the most rigorous climate of Madagascar with frosts at the superior altitudes as well as snow that can remain during several days above 2500 meters of altitude.
The flora
Several types of vegetation can be found in the reserve : subhumid evergreen forests , mountains thicketsas and grassy areas. Forests change with the altitude, trees become smaller, more branchy , show more epiphyt plants , ferns and lichens. The canopy does not reach 10 meters high at 2000 meters of altitude. Orchids are numerous in altitude that in the plateau grassy areas where several species of aloés can also be seen . Plants communities are different the dry western slopes and some areas are dominated by the tapias.
The fauna
This reserve shelters the greatest number of lemurs ,at least 14 species, and mammals : on western slopes , the Maki , the most known lemur at the south of Madagascar lives together with other lemurs of the west .. Nine species and under species are met on the eastern slope against five species on the western slopes . The Andringitra site protects the greatest number of small mammals including rodents and insectivores of the Tenrec family. Carnivores are represented by five Malagasy species among them the Fosa. Birds have been studied only on eastern slopes where 99 species have been counted : four species of land Rollers and nine of Vangas can be found in the forest community. Many reptiles and amphibians are known from eastern slopes but they are more numerous at low altitudes. Among them, there is at least six amphibians and four reptiles that are particular to the mountain.
