Site description Subri River Forest Reserve is located c.16 km south of the railway line linking the towns of Huni Valley–Twifo Praso and c. 21 km from Daboase village. The site is only some 3 km from the Pra-Sushien Reserve (GH018) and is the largest Forest Reserve in the country. The topography is generally undulating with altitudes in the range 60–125 m, but in the northern, south-eastern and central parts are steep-sided hills that reach 300 m. The reserve forms part of the watershed between the Bonsa and Pra rivers and is traversed by tributaries of each, resulting in extensive areas of swampy vegetation which make access difficult even in the dry season. The vegetation is moist evergreen forest, but wet evergreen forest is reported to occur in some parts. Some areas of the reserve were subjected to salvage felling between 1966 and 1976, followed by selective logging since 1978. Some 12,372 ha have been converted to plantation.

| Notes: Collection of dead wood for firewood. | |
Other biodiversity Tragelaphus euryceros (LR/nt) is reported to be common; Panthera pardus and Profelis aurata have been sighted by hunters in recent times.
Management considerations The area was designated a Forest Reserve in 1950. It is rated a Condition 3 forest (though some areas are reported to be in good condition), with GHI of 107–207. Of the total area, 5,120 ha has been designated as a Globally Significant Biodiversity Area by the Forest Department. There is evidence of some gold mining. Local people have the right to collect deadwood for firewood.
