4.2. Status of forests in Nigeria.
The current status of forests in Nigeria is based on the work of Beak Consultants for FORMECU titled "The Forest Resources Study (FRS) of Nigeria". Table 3 below shows the area of various forest types in the forest reserves and free areas. The total areas of these forest categories are also provided.
