Abstrakt: Conversion of watershed ecosystems to other land use systems has impacts on environment. This study therefore investigated effects of Land Use Types (LUT) on sustainability management of watershed. The watershed of Ijaye forest reserve was stratified into three LUT: Natural Forest (NF), Disturbed Forest (DF) and Farm land (FL) for floristic survey and regeneration potential investigations. Systematic line transects was used in the laying of the sample plots in NF, DF and FL along the river which meanders through Ijaye Forest Reserve. A total of 45 tree species from 17 families were identified. The NF had the highest tree density of (1012±37 trees/ha) while FL had the lowest (74±16trees/ha). The NF was dominated by upper canopy (30-40 m) with 56.4% while FL had 1.6% of lower canopy (20- 30 m). The LUT has important implications on forest structure, species diversity and sustainable management of watershed ecosystems. [ABSTRACT FROM AUTHOR]
