The Ranomafana National Park, inaugurated on May 31, 1991, is located in central Madagascar, 60 km from Fianarantsoa. Located in a mountainous area (600 – 1400 m) it occupies an area of 410 km² covered by a dense rainforest. Inside there are 12 species of lemurs, the fanaloka, the ring-tailed mongoose, the common tenrec and the very rare aquatic tenrec. Since 2007, the park has been part of the Atsinanana Rainforest Complex, a UNESCO World Heritage Site.
The park was established in 1991 with the purpose of conserving the unique biodiversity of the local ecosystem and reducing the human pressures on the protected area. It is part of the World Heritage Site Rainforests of the Atsinanana. Adjacent to the park is the Centre ValBio research station, established in 2003 and managed by Stony Brook University with a focus on biodiversity research, community health and education, environmental arts and reforestation.
