Site description
Bidia Classified Forest lies c.30 km north-east of Andilamena. The site is a network of mountains, peaking at Bidia (1,200 m), which is part of the Marovoalavo plateau. The hydrological network is dense and dominated by the Befiaka, Vakoanina and Bidia rivers. The primary vegetation is composed of mid-altitude, dense, humid evergreen forest (frequently 25–30 m high), dominated by trees of Weinmannia, Dalbergia, Canarium and Eugenia. There are also secondary formations of traveller’s palm Ravenala and fallow areas dominated by Solanum and Harungana.
