Site description The Biseni forests are located north-west of Ahoada (itself some 50 km north-west of Port Harcourt), just west of the Upper Orashi forests (NG015), in the Taylor Creek flood-plain of the Niger Delta. The forests are seasonally flooded during the rains, but dry out during the dry season leaving numerous small forest lakes. Raphia palms and some woody broadleaved species such as Symphonia globulifera and Ficus spp. are common. There are also areas of tall grass swamps close to the river channels.
