Timber exploitation data that are very essential f or sustainable management of the forest resources, where available in Nigeria, are not anal yzed and studied to provide information on the rate of log removal from the forest estate. Timber exploita tion rate in Nigeria using Ondo State as a case stu dy was examined in this study. Secondary data on the v olume and number of economic timber species exploited from the reserved and free areas forests in four forest administrative zones on monthly basi s between 2003 and 2005 were collected from the state department of forestry. Analysis was done with student t-test and two-way analysis of variance. Th e result revealed that the highest number of specie s, families and stems was exploited in the free areas when compared with what was exploited from the reserves for the three-year period. During the stud y period, a total of 60 and 57 species were exploit ed from the free areas and the reserves respectively f rom the four administrative zones. The total number of stems exploited from both the free areas and reserv totaled 111377 with an estimated volume of 295089.67m. A steady increase was recorded in logging activit ies between year 2003 and 2004 but there was a decline in year 2005. This reveals how fast e conomic timbers are disappearing from the forests a nd consequently, how the ecosystem is seriously distur bed during logging activities. Principles for achie ving the goals of sustainable forest management (SFM) an d urgent conservation measures to mitigate these consequences were suggested.
