2 Background Study area Methods Results Conclusions

3 The object of forest management has been observed to influence forest canopy dynamics The Kakum Conservation Area, a 360km 2 contiguous rainforest of Ghana suffered logging from 1936 to 1989 In 1990, the management was changed from timber production to conservation of biodiversity

4 To evaluate the dynamics of canopy recovery of rain forest after logging The specific objectives were: to investigate the effect of change of object of management on forest canopy coverage to evaluate the magnitude of forest canopy recovery after logging

5 Kakum Conservation Area

6 It is a contiguous forest that lies between longitude 1°51W and 1°30W and latitude 5°20N and 5°40N 210km 2 Kakum National Park 150 km 2 Assin Attandanso Resource Reserve

7 Legally gazetted as a national park and resource reserve respectively in 1991 Under the Wildlife Reserves Regulations L.I 710 As amended by L.I 1525 Under the administrative jurisdiction of the Wildlife Division of the forestry commission

8 The area was initially placed under timber production by the Forestry Department until 1989 Before 1936 (Prior to timber exploitation) : the reserve was more or less a virgin forest There was no evidence that farming might have taken place in the reserve for any considerable length of time (Paijmans and Jack, 1960)

9 : Timber exploitation with mahogany (Khaya ivorensis) being the principal species logged : Other timber species were included for exploitation 1990: The management was transferred to the Wildlife Division

10 The conservation area has gone through a long period of disturbances as a result of commercial hunting subsistence hunting gathering of non-wood forest products timber logging About 52 communities are scattered around the conservation area

18 The reduction of opened canopy and increase in closed canopy area could be attributed to the change of selective timber logging to wildlife conservation area The farming areas at the peripheries has increased probably because: many timber workers engaging in farming activities the illegal farmers that were driven out of the forest Immigration

19 Forest reserves, undergoing convalescence must be managed from the conservation approach A large proportion of the plants and animals in tropical forests should be protected through the establishment of conservation areas
