Assessment of land degradation status of three forest reserves under teak and gmelina planta-tion in South-West Nigeria

This study assessed the degradation status of the three forest reserves along a toposequence under exotics plantation of Gmelina arborea and Tectona grandis with the aim of evaluating the deterioration level of the soil productivity in re-spect to human disturbance. Surface samples at depths of 0 - 15 cm and 15 - 30 cm were collected and soil laboratory analysis carried out to determine the soil properties of each site. Direct approach method was used to assess soil degrada-tion status of these soils. The direct approach method showed that the soils at the three locations, both under teak and Gmelina plantation were seriously degraded physically, chemically and biologically. Onigambari were more degraded physi-cally, chemically and biologically than other two locations with higher degrada-tion in the upper slope segment. The type and degree of degradation observed on the two land use types across the locations are major factors to be considered in determining the suitable approach to soil improvement for sustainable manage-ment and production of timbers and non-wood products in our plantations.
