Vegetation modification and man-induced environmental change in rural southwestern Nigeria

The nature and pattern of vegetation modification and environmental change in the tropical rain forest of southwestern Nigeria were examined. The study considered some biotic and edaphic parameters in two different areas. The changes were determined by comparing these parameters, with those in a tra...

Description
Summary:The nature and pattern of vegetation modification and environmental change in the tropical rain forest of southwestern Nigeria were examined. The study considered some biotic and edaphic parameters in two different areas. The changes were determined by comparing these parameters, with those in a tract of mature forest. The results depict the extent to which the soil-vegetation system, in the area has been disrupted, by both regulations and the activities of peasant farmers. The activities of the farmers, have resulted in degradation of the structural complexity, of the vegetation and a deterioration of soil quality. The changes depicted in this study could only be said to be a temporary disruption, if the area is allowed sufficient time to recover. Alternative environmental management strategies are suggested.
