the reserve has no management plan (Thomas, 1994; ERM, 1998; <strong>Sunderland</strong> and<br />

Tchouto, 1999).<br />

3.3.2.2 Climate<br />

Annual precipitation on the Western flank <strong>of</strong> Mount Cameroon varies between<br />

3,000mm and 4,000mm and declines further east <strong>of</strong> Mokoko in a rain shadow caused<br />

by the Mount Cameroon massif. There is a single rainy season between March and<br />

October. December, January and February are all relatively dry months, <strong>of</strong>ten with no<br />

rain falling at all. The annual mean temperature is 27°C.<br />

3.3.2.3 Topography, geology and soil type<br />

The Mokoko FR is situated at an altitude between 120 to 360m, on the north west<br />

inferior slope <strong>of</strong> Mount Cameroon. The majority <strong>of</strong> the reserve is seated on ancient<br />

volcanic rocks, basalts and trachites. Nearer the sea, there are small areas <strong>of</strong> more<br />

recent alluvial deposits. The soils that predominate within the reserve have been<br />

formed by an association between ancient and recent volcanic material with a small<br />

area <strong>of</strong> non-volcanic sedimentary sandstone-derived soil nearer to the Boa Plain<br />

(ERM, 1998).<br />

3.3.2.4 Vegetation<br />

The majority <strong>of</strong> the lowland forests in the hinterland <strong>of</strong> Mount Cameroon have been<br />

converted to industrial plantations, and the forests <strong>of</strong> the Mokoko area currently<br />

constitute the only pristine and most extensive forest formation in the region. As such,<br />

they are extremely important, both in terms <strong>of</strong> biodiversity value (Cable and Cheek,<br />

1998) and for indigenous use and management (Sharpe, 1998; <strong>Sunderland</strong> and<br />

Tchouto, 1999).<br />

The vegetation <strong>of</strong> the Mokoko Reserve was originally described by Letouzey (1985)<br />

as being <strong>of</strong> the “Atlantic Biafran evergreen forest with numerous Caesalpiniaceae”<br />

formation. Whilst this general description certainly encompasses the general<br />

physiognomy <strong>of</strong> the area, Letouzey’s classification, at 1:500,000 scale with limited<br />

ground-truthing, does not allow for more subtle variations in vegetation that are<br />

characteristic <strong>of</strong> the forests around Mount Cameroon. As such, subsequent field-work<br />
