9.1. Forest Resources Management Plans and Maps
Beak Consultants have identified three types of management units in the high forest areas of the country. These units are based on major forest types, which closely relate to the ecological zones within Nigeria. These management units are designated as follows-
(a) Lowland rain forest MU1
(b) Fresh water Swamp forest MU2
(c) Mangrove forest MU2
Table 18 is a list of the high forest States with their associated management unit

MU 1 – Lowland Rain Forest – Freshwater Swamp Forest, MU3 – Mangrove Forest2
Includes mangroves with tress and without trees.Source: Beak Consultants 1998. Forest Resources main Report (Draft) Vol. II page 5-9.
Beak Consultants of Canada have prepared management plants for each of the 24 study states. Estimates have been made for Gross standing volumes, industrial timber Volumes and Plantation information for the States. Tables 19a, 19b, 19c, 19d and 19e provide these estimates for Osun State. A forest resources map for each of the FRS State was also prepared by Beak Consultants showing major forest resources. The scales of the state maps are not uniform.
