Tsitongambarika is a lowland forest in southern Madagascar. The area supports many rare species of amphibians, birds, lemurs and reptiles; many of which are endemic. In 2001, the site was designated as an Important Bird Area by BirdLife International and in 2015, an area of 600 km² received environmental protection by the government. The reserve is the recipient of monies raised by the 2016 Rutland Birdfair.
