Kalambatritra Special Reserve


Year of compilation: 2001

Site description
Kalambatritra is located 40 km east of Betroka. The terrain of undulating hills and steep summits is part of the Antaivondro-Kalambatritra mountain chain. Many clear and permanent tributaries of the Mangoky and the Ionaivo have their sources in the reserve. The low- and mid-altitude, dense, humid evergreen forest is little disturbed, and has a canopy 15–25 m high with emergents reaching 30 m. Characteristic trees include figs Ficus, Dalbergia and tree-ferns Cyathea. The humus layer is 10–25cm thick. Savannas of coarse grass (Aristida, Imperata) divide the forest into blocks, and a strip of bracken Pteridium borders the forest. The border of the protected area includes large areas of savanna.

Key biodiversity
See Box and Tables 2 and 3 for key species. Seventy-four species are known from the site, of which 45 are endemic to Madagascar. The species found are characteristic of humid forest, despite the site being located at the edge of the Eastern forest area.

Non-bird biodiversity: Lemurs: Eulemur fulvus collaris (VU), E. rubriventer (VU).



Pressure/threats to key biodiversity
Grazing of livestock is the only human activity known to constitute a threat.
