This study examined the impact of forest loss by fragmentation along four communities that taboo the species of primates and reptiles. Data by survey at three sighting regimes in a3×2×5 factorial experiments were square root-transformed before the analysis of variance and significant means separated at 5% level of probability with the Duncan multiple range tests. The fineness/coarseness of forest corridors and edges, availability of propagules and a-subjective habitat-matrix score for 7 key attributes of forest fragmentation along with soil samples analyzed for CEC, exchangeable cations and Ca-Mg ratio. Results showed higher mean population sighted in corridors than that of the edges. Propagule availability was Ugili Amai-Olloh Ossisa (18.5 kg/ha) >Ugono-Orogun (16.8 kg/ha)>Umute-Nsukwa (15.2 kg/ha)>Emu Uno (10.8 kg/ha) and underpinned intact fragment as Umute-Nsukwa>Ugili-Ossisa>Ugono-Orogu> Emu-Uno for the protection of IUCN Red List vulnerable white-throated guenon (Cercopithecus erythrogaster) and threatened West African dwarf crocodile (Osteollaemus tetraspis).
