Records on rate of timber exploitation are very essential for sustainable forestry. They help in managing the forest sustainably. Therefore, the study collected and analysed data on rate of timber exploitation in Shasha forest reserve in Osun state. Logs arranged and set to be taken out of the forest were identified and measured every Monday between December, 2017 and June, 2018 for twenty-eight (28) weeks. The species and families of logs encountered were identified. A total of 13,944 logs were assessed. Fifteen (15) families belonging to twenty-one (21) species of logs were identified. Result revealed that Sterculiaceae family with five species was the most exploited. Ricinodendron heudelotti has the highest number of exploited logs with overall frequency of 27.71%. Ricinodendron heudelotti had the highest basal area and volume with values of 18018776.71cm² and 113289.36cm³ respectively. The study concludes that the population of Ricinodendron heudelotii tree was high in Shasha forest which made it available for extraction at high rate. The study recommends strict monitoring and enforcement of sustainable forestry laws with regular inventory and up-to-date inventory of timber exploitation rate from the reserve.
