Ecology of Patas Monkey (Erythrocebus Patas) in Buffer Zone Ranges, Old Oyo National Park, Nigeria

Abstract

The buffer zones of Nigerian protected areas are poorly managed. Patas monkey (Erythrocebus patas) was studied in fact owing to its dearth of information on its ecology and existence in South-West Nigeria National Park. Therefore, it was necessary to examine E. patas spatial distribution and population structure in the Old Oyo National Park buffer zone ranges, situated in South-West Nigeria and as well know its dietary uptake alongside delineating its various activities. Observations were positioned on direct census methods. A total of 60 individuals of E. patas (23 female, 21 male, and 16 young individuals) were sighted within the study period (March to July). The results showed that the highest number of sighted E. patas (18 individuals) was recorded in the month of March while the Marguba range had the highest percentage of sighted E. patas (31.7%). Thirteen plant species were identified as food matters of E. patas while the major activity observed by the majority of E. patas was found feeding on the identified food matters. The food matters consumed were plant parts which included the leaves, flowers, gum, enflamed spikes, and fruits. Actions to uphold and guard the remaining populace of E. patas in the Park and buffer zones should be adequately fortified.
