“…It can also be attributed to selective exploitation (as evidenced in Mkpok forest) of these plant species which may have led to slow rate of regeneration and low ecological tolerance (Kabir et al, 2008). Furthermore, the species composition in the forests corroborates with the findings of (Onyekwelu et al, 2005;Ukpong et al, 2012;Udoakpan et al, 2013;Daniel et al, 2015 andJacob et al, 2015). These researchers reported that within the southern rainforests, a number of forest types can be recognized, some are rich in species of family Sterculiaceae, Moraceae, Meliaceae, Euphorbaceae, Mimosaceae (Fabaceae) and Apocynaceae with a middle storey of dense-crowned, wide-spreading trees and a ground flora that is mainly herbaceous and characterized by an abundance of creepers, mostly Acacia sp.…”

As efforts are geared towards preventing the utter destruction of our ecosystem and ensuring the conservation of our rich biodiversity, adequate quantitative and qualitative ecological data of the flora and fauna species are imperative. Accordingly, the status of phytodiversity and pedological properties were assessed in a tropical forest fragment namely Mkpok Village Forest (MVF) in Akwa Ibom State (AKS). This was with a view to providing insights into its environmental determinants; as well as baseline for the management and conservation of the forest fragment. Systematic sampling method was used to sample the vegetation using a quadrat size of 10 m x 10 m. The frequency, density, height, basal area and crown cover of plant species encountered were determined. Twelve composite soil samples were collected and analyzed for pedological properties (soil pH, texture and chemical constituents) using standard analytical procedures. Forty-two plant species belonging to thirty families were encountered. Family Fabaceae had the highest number of 6 plant species followed by Meliaceae, Arecaceae, and Euphorbiaceae with 3 plant species each. The tallest and shortest tree species were Piptadeniastrum africanum (22.91 ± 2.33 m) and Cannarium schweinfurthii (2.00 ± 0.51 m). Shannon-Wiener and Simpson diversity indices of 2.88 and 0.90 were recorded respectively. Pedological analyses revealed that in MVF the soils were moderately acidic and highly sandy, having low concentrations of some plant nutrients. Correlation analysis indicated relationships between some vegetation parameters and soil chemical constituents (p=0.05). It is concluded that the forest was not structurally complex as expected of a tropical rainforest partly due to anthropogenic activities but possessed attributes of a typical rainforest of Nigeria thus reinforced the hope that this forest fragment if preserved can return to its primary status.

“…Where PD = population density, n = number of individuals, l = length of the transect (m), w = width of the transect (m), and a = area of the transect in km 2 [13]. The relative dominance, frequency, relative density and importance value index were determined using the formula: (Jacob et al [6,13])…”

“…Distortions in habitats and tree composition will imply that the monkeys will have to navigate between patches of forest for food cover and shelter, which will further predispose the species to other environmental hazards. Absence of preferred animal food in required amount can cause species population to shrink, thereby affecting the quality and health of the ecosystem [6].…”

Aims: Effect of tree species composition and food selectivity on the population density of the Sclater’s guenon was carried out to determine how habitat composition and food preferences affect population density of the Sclater’s monkeys in the study area. Place and Duration of Study: The study was carried out in forest patches of Lagwa community in Aboh-Mbaise Local Government Area, Imo State (December 2019-November 2021). Study Design: The point centered quarter method was used to collect data on trees species, while the visual observation and line transect methods was used to collect data on food preference and population density of the monkeys. Methodology: The research was carried out within the wet and dry season. Faecal examination was used for collecting information on plant and fruit species consumed. Results: The most dominant tree species were Khaya ivorensis and Treculia africana with important value index (IVI) of 35.13 and 26.73 respectively, while Bosqueia angolensis was the least dominant species with IVI of 0.99. Tree species with diameter at breast height class of 41cm and above were absent in Eziudo, Obo and Umunekere communities. Dacryodes edulis, Elaeis guinensis, Mangifera indica and Musa balbisiana were the most consumed plant species. The mean troop sizes were 3.21±1.42 for the dry season and 2.78±1.25 for the wet season, with troop density for both seasons as 0.03±0.02. Conclusion: The findings presents the relationship between the Sclater’s monkey’s diet and their habitat, and how habitat changes can cause changes in the feeding pattern, type of food and meals consumed. Sensitization campaigns and provision of alternative food sources for humans can reduce disturbance of the habitat and further sustain the population of the monkeys.

Abstract:Measuring the efficiency of a national park is difficult due to, among other factors, the heterogeneity of resources supplied (e.g., budget, staffs) and outcomes expected (e.g., income, visitors' flow). While this is an issue in protected area management, it has been approached successfully in other fields by using data envelopment analysis (DEA). DEA has a number of advantages over other techniques as it simultaneously uses multiple heterogeneous inputs and outputs to determine which projects are performing most efficiently, referred to as being at the efficiency frontier, when compared to others in the data set. This study therefore uses DEA for the evaluation of management efficiency in Old Oyo National Park for the period of 2001-2015. The results showed that the park was efficient for 11 and 13 years, respectively, in terms of its overall technical and pure technical efficiency with a mean scale efficiency of 97%. Also, the park operated at 80% of its productive scale size. These results, and the use of DEA, highlight both the success of using this technique in helping determine protected area efficiency and those factors to consider while allocating resources for new projects at the park.
