Mangerivola Special Reserve is a wildlife reserve in the east of Madagascar. It was established in 1958 and is a hotspot for bird-watchers due to the one hundred species found there, including 63 endemics and many local endemics. There are also seven species of lemur and rare chameleons such as the Lance-nosed chameleon (Calumma gallus) which is registered as endangered on the IUCN Red List of Threatened Species.

Geography
Mangerivola Special Reserve is a 13005 ha nature reserve in the Atsinanana region, to the west of Toamasina and south of Fito. The highest peak on the reserve is Mangerivola at 1484 m and the landscape consists of hills, deep valleys, waterfalls (up to 80 m) and lakes. Two of rivers (Ambotohaka and Ivondro) provide water for the hydroelectric power at the Volobe dam, and along with the Marongolo, Ranomena and Sanalaotra rivers, irrigate the rice fields below the reserve and supply drinking water.

There are few visitors due to the steep terrain and impassable roads during the wet season.

Flora and fauna
The natural vegetation on the reserve is dense, low- and mid-altitude, humid evergreen forest. Anthostema madagascariense, Myristicaceae and Sarcolaenaceae are the dominant trees in the low-altitude forest, and Burseraceae, Cunoniaceae, Ebenaceae, Monimiaceae and Myrtaceae in the mid-altitude forest. In the north and north-east the old-growth forest has been cleared and there is some secondary forest growth with Harungana madagascariensis and traveller's palm Ravenala madagascariensis. The reserve has 325 species of plant of which 170 are endemic.
