The extent of any forest determines its capacity to supply goods and services which are indispensable for man’s continued existence. However, increasing population of humans subjects forest under pressure to meet basic needs of man thereby modifying its extent mostly through deforestation and forest degradation. It therefore became necessary to investigate the extent of Osho Forest Reserve, Nigeria (longitudes 3o25' and 5o00'E, latitudes 7o00' and 7o45'N) with the use of Landsat imageries of 1984, 2000 and 2006. The imageries were georeferenced to the same coordinate system using topographical map of the study area. Bands 2, 4 and 5 were used since they are suitable for vegetation studies. Idrisi32 and ArcGIS 8.1 were used for the analyses and map production respectively. A supervised classification theme of Natural Forest (NF), Plantation and Farmland was adopted after reconnaissance survey in the study area. NF which covered 93.8% in 1984 shrank to 4.0% in 2006, Plantation had occupied 6.0% in 1984 but increased to 9.0% in 2006 while Farmland significantly increased from 0.2% in 1984 to 87.0% within the same period. Although Plantation and Farmland increased over the study period, the declining NF extent has grave implications on the abilityof this forest ecosystem to sustainably deliver its benefits.
