The Assessment of forest species composition and species diversity is essential in understanding the status of tree population and diversity for conservation purpose. Olokemeji forest reserve is situated in the lowland rain  forest of south-western Nigeria and it occupies a total land area of 58.88 km2 . Six study plots of 50m2 each were randomly selected and designated as Frequently Burnt Plot 1, Frequently Burnt Plot 2, Harvested Plot, Unharvested Unburnt Plot, Arable Plot 1 and Arable Plot 2 for the purpose of assessment of species diversity and distribution of woody species. Seven species of trees were identified belonging to five families. One hundred and eighty two stands were enumerated, with Unharvested Unburnt Plot having the highest number of trees at 50. The dominance index for the woody flora was 1 in Frequently Burnt Plot 1 and 2 as well as Arable Plot 1 and 2 except for the Harvested Plot that had the lowest (0.29) while the Unharvested Unburnt Plot had 0.75. Highest species richness was recorded at the Harvested Plot at 0.71. The species diversity in Harvested Plot was low (1.54), while it was extremely low in Unharvested Unburnt Plot (0.43). Evenness index was lowest in the Unharvested Unburnt Plot at 0.43. Tectona grandis had the highest relative importance value in the Frequently Burnt Plot 1. The low species richness and species diversity is a direct indication of anthropogenic interference in the study plots and the forest reserve; this requires urgent mitigation to prevent a total loss of its structure and function as expected of a forest reserve.

Effects of forest fire on the regeneration potential of trees at Olokemeji Forest Reserve was established in this study. The Olokemeji fire experimental plot was selected at the reserve. The site was divided into three plots; late fire treatment was applied to Plot A, Early fire treatment was also applied to Plot B and no fire treatment at plot C (Control plot). The diameter at breast height (dbh) and tree height (m) of the tree species in the plots were assessed prior and post fire treatment. The regeneration potential of the selected plots after burning were assessed through the occurrence of saplings and seedlings obtained. The highest basal area (m2) were found in plot C followed by plot B and Plot C with mean value of 0.64, 0.55 and 0.30 m2 respectively. The number of stems per plot ranged from 25 to 67. The regeneration potentials of the three plots were found to be noteworthy. Early and late year fire regime adopted had both positive and negative effect on the regeneration potentials of tree species. This study has established the effect and relevance of fire on forest and wildlife management. It’s therefore recommended in this study that Prescribed or controlled burning should be encouraged as appropriate sivilcultural management tool for stimulating basal area growth, natural regeneration, production of tree species seedlings and saplings.

Determinants of participation in the collection and sales of forest plant leaves in Ogun state were investigated. Multistage sampling procedure was employed to select three hundred (300) respondents for the study. A structure questionnaire was used to elicit information from the respondents. Data obtained were analyzed using descriptive statistics, logit regression and budgetary analysis. The logit regression analysis results showed that the likelihood of utilization of the forest plant leaves is significantly determined by nature of the respondents occupation (farming and NTFPs) and their household size while the likelihood of participation in the collection and sales of forest plant leaves is significantly determined by nearness to the forest plant leaves, income realized from the leaves and gender. Sales of leaves were profitable with an average net profit of N14,179.17/month/respondent. Enlighten programs on forest plant leaves activities as means of livelihood and alleviation of poverty should be embarked upon for rural folks.

The study investigated evaluation of economic impact of non-timber forest products collections in Arakanga forest reserve in Ogun State. Purposive sampling was used to select four villages around the reserve, representing 10% sampling intensity in the study area. A total of 98 questionnaires were administered. Data were analyzed using descriptive statistics and budgetary analysis. Majority of respondents were within the age group of40-49 years (35.7%) and mostly were female(51%),40.8% had no formal education while 33.7% had primary education and were mostly married(57.1%). Identified NTFPs includes fuelwood, mushroom, charcoal and honey. The result on profitability showed that fuel-wood had the highest net profit (₦10,916.85) among the NTFPs found in the study area. Constraints faced NTFPs were price fluctuation (58.2%), low demand (14.3%) and inadequate credit facilities (11.2%) and host of others. It was recommended that NTFPs should be introduced to youth in orderto reduce the level of unemployment and government should repaired the road network to the forest for easy accessibility for NTFPs operation.

High Dominance

The fire experimental plot of a total landed area of 0.174 ha was divided into three equal parts designated Plot A, Plot B and Plot C, corresponding to the early burnt, the late burnt and the control plot, respectively. Out of the 15 species of trees identified, six species belong to Fabaceae- Mimosoideae family and other families represented are Combretaceae, Meliaceae, Lamiaceae, Rubiaceae, Anacardiaceae, Urtiaceae and Sapotaceae. Gmelina arborea was the most abundant species and it was found in plot A, B and C. The diversity indices enumerated were Dominance index, Simpson index, Shannon index or diversity index and evenness index. Plot C had the highest abundance (species count), followed by Plot A and Plot B. While Plot B depicted a high dominance, dominance was low in Plot A and lowest in Plot C. This means that a particular species was dominating Plot B, which was Gmelina arborea. This Gmelina arborea also dominated Plot A but to a lesser extent compared to Plot B. Plot C was richer in species than Plot A and Plot B. The Shannon index was low across the three plots, but considerably highest in Plot C. Evenness index was moderate at Plot C, implying that there was an even distribution of tree species in Plot C, while evenness was low at Plot A and Plot B. Comparing the present data with the older data, it is clear that the fire experimental plot has undergone deforestation over the years, which requires urgent attention and reforestation.

Abstract The Hoffmann’s two-toed sloth (Choloepus hoffmanni) is a species which could potentially be evaluated as threatened, but data on its natural history in wild conditions are still insufficient. The diet in wildlife of C. hoffmanni was studied through of microhistological analysis of indigestible fragments of leaves found in 43 feces samples collected of the 47 samples found in an Andean forest reserve south of Bogotá, Colombia. Four samples were highly decomposed and were not collected. A reference collection was made of 29 tree species where the feces were found or two-toed sloth were observed, to compare with the plant fragments found in the feces. Seventeen species and six fragments of foliar epidermis of undetermined species were identified in sloth diet. Based on this analysis, C. hoffmanni is a generalist folivore, ingesting a wide variety of plant leaves. Based on frequency of occurrence, relative frequency, and percent cover by volume, Brunellia sibundoya, Cordia cylindrostachya, Citharexylum sp., Quercus humboldtii, and Clethra fagifolia made up most (74%) of the diet of C. hoffmanni in an Andean forest. Comparing the plant species found in the feces with the reference collection, C. hoffmanni appears to deposit feces at the base of the trees that it consumes.

Floristic Structure

Total enumeration of tree species was carried out fire experimental plot of Olokemeji forest reserve for relative importance value (RIV) mean heights, mean diameter at breast height and mean basal area. Three investigative plot (Plot A, B and C) were established. Plot A which represents Early Burn is burnt annually during the dry season while Plot B was burnt annually during the rainy season when the trees are still wet and Plot C serves as the protected area. Gmelina arborea had the highest relative importance value (28.31), this is followed by Dalbergia sissoo which had RIV of 10.94. Plot C recorded the highest frequency of trees with the highest tree heights, this is closely followed by Plot A and Plot B being the plot with the lowest mean height. Plot C has the highest mean diameter at breast height (DBH) of trees and it is followed by Plot B and Plot A with very close mean DBH. The highest mean basal area was also recorded in Plot C, the highest total basal area and tree volume was also recorded at Plot C as 32.2 m2 ha-1 and 188.8 m3. The size distribution of tree species depicts that Plot C has been protected just as expected Keywords: Forest, Structure, Flora, Dynamics, Fire
