Assessment of Population Abundance, Density and Habitat Preference of Sclater’s Guenon (Cercopithecus sclateri Pocock 1904) in Aboh-Mbaise Communal Forest, Imo State, Nigeria

Abstract

Aims: We assessed the population abundance, density and habitat preference of sclater’s guenon (Cercopithecus sclateri) in Aboh-Mbaise communal forest to inform conservation efforts for the species now and in the future.
 Study Design: We used the point count sampling method to estimate population size.
 Place and duration of study: The study was carried out in Lagwa communal forest, Aboh-Mbaise Local Government Area, Imo State, between December 2019 and November 2021.
 Methodology: We laid-out eight 2.5-km transects in a land area of 28,500km2. We enumerated and measured trees using the point-centered quarter method. 
 Results: Results of this study indicated that they were 738 individual monkeys, 392 in dry and 346 in the wet seasons. The population density was 0.04 ± 0.01 individuals/km2, with troop sizes of 4.09±0.83 and 3.68 ± 0.75 for dry and wet seasons, respectively. The monkeys were sighted mostly in secondary forest, sacred groves, and economic trees. Most of the trees were within the diameter-at-breast-height class of 21cm-30 cm. A total of (304) plant species were used by the monkeys for cover in both seasons; these included Dacryodes edulis, Elaeis guinensis, Magnifera indica, Treculia africana and Pterocarpus erinaceous.
 Conclusion: The findings of this research is a prelude to understanding the population dynamics and habitat structure of the sclater’s guenon in the study area. Massive sensitization of the locals, regeneration of the remaining fragmented habitat and establishment of a wildlife sanctuary are needed to allow conservation of the species and its habitat.
