Site description (2001 baseline)
Upper Rantabe Classified Forest is located 90 km south-west of Maroantsetra. The terrain is a succession of mountains and valleys. The Vohilava river flows through the site, as do many permanent or seasonal streams. The vegetation is composed of intact and degraded low-altitude, dense, humid evergreen forest. The canopy layer of intact forest is composed of spur- and stilt-root trees 20–25 m high, dominated by Dalbergia and Tambourissa, while the mid-stratum is dominated by shrubs and abundant tree-ferns Cyathea, and the ground layer is formed of small plants and grasses. Secondary thickets in degraded forest are composed mainly of Solanum and Lantana bushes, and wild ginger Aframomum.
