The Tano-Nimiri Forest Reserve shares a common boundary with Boin-Tano (GH004) and is about 4 km from the Tano-Anwia Reserve (GH020). A number of streams and rivers, including the Nimiri river, flow through the reserve and drain into the Tano river, on which there is a waterfall, the Atangwen Falls. The terrain between the rivers is rugged, with steep slopes and valleys that flood during the rains. The reserve spans two vegetation-types: the southern section, approximately one-third, is wet evergreen forest, while the remainder is moist evergreen forest. The reserve has been subjected to intensive logging, starting from the mid-1950s and continuing to 1992. Approximately 10% of the reserve was planned for either enrichment or afforestation planting in the early 1980s. Under the taungya system, 975 ha (c.5% of the total) has been converted to Cedrela and Triplochiton plantation and there are also farms in the reserve.

Pressure/threats to key biodiversity
The area was gazetted a Forest Reserve in 1955. It is rated Condition 3 (GHI 70–157), with much of the forest heavily disturbed. More recently, 3,456 ha have been designated as a Globally Significant Biodiversity Area by the Forest Department. Non-timber forest produce exploited includes raphia palm, oil-palm, canes and poles. Evidence of past mining activities along the banks of the Tano river is still visible.
