Abstract
This study identified the management strategies in operation at the Omo Forest Reserve in Southwestern Nigeria; It also quantified land use and land cover in the study area between 1986 and 2020; and inventories of forest resources in the study area. It further examined the correlation between management strategies and land cover degradation in the Omo Forest reserve in Southwestern Nigeria. These were with the view of providing information on the significance of land cover dynamism to sustain woodland resource protection and preservation in Omo Forest Reserve Southwestern Nigeria. Primary and secondary sources of data were utilized for the study. This study adopted a descriptive survey research design and use both primary and secondary data. The primary data include geographic coordinate points of relevant features within the study area. Key Informant Interview (KII) was conducted with Foresters and Rangers focusing on flora and fauna inventorisation in order to identify the status of differently species and also, to identify management strategies operational in the study area. The secondary data includes topographical sheet 69 NE, 1963 of the study area and its environ which was used as base-map. In addition, Multidate Landsat images was acquired ( Lansat 5 MSS/TM, 1986; Landsat 7 ETM+, 1999 and 2012; and Landsat OLI/TIR, 2019) due to availability and relevance. Indices includes Shanon’s Diversity Index (SDI), Cellular Auomata (CA), Normalized Difference Vegetation Index (NDVI) using ENVI 5.3, among other recognized biogeographical indices. Data collected was analyzed using geospatial techniques in geographical system (GIS) mode, preferably the open- access QGIS. The result identified protected area system, plantation establishment, Taungya system, afforestation and selective management system and wildlife management and dominant forest xii management strategies in the study area. Result also showed that major land use/cover in the area varied as 0.6% - 5.6% (built-up), 11.68% - 21.83% (farmland and open surface), 16.61% - 20.04% (plantation) and 0.29% - 0.25% (water body) between 1986 and 2020. Result further listed thirty-eight (38) plant species as critical endangered and eight (8) animal species as critically endangered within the study period. Lastly, management strategies exhibited strong correlation (r = 0.68) with land cover change in the area; such that management strategies which promoted conservation and reforestation and afforestation produced health (greener) vegetation in the area. The study concluded that management strategies and land cover dynamics in the study area is significant to the establishment of a sustainable woodland resources protection and preservation.
