Abstract: The Moist Evergreen Afromontane rainforest, which grows at altitudes of 1500 to 2600 m, dominates the forest vegetation in the highlands of Ethiopia. It is consequently critical to have a thorough understanding of particular vegetation's floristic composition, structure, and relationships in environmental elements that surround this thing. The investigation had been carried out on Nono Sele Forest in the Ilubabor Zone of Oromia National Regional State, in the south-west of Ethiopia, with the objective of deciding the vegetation structure, community type, as well as natural regeneration condition for woody species in the forest. A systematic sampling procedure was used to gather vegetation data. To cover most of the representative of the forest, a total of forty-six plots of 400 m2 (20 m x 20 m) for trees, within the main quadrat sub-plots of 25 m2 (5 m x 5 m) for shrubs, herbaceous and climber species, at each corner of the main plots and in the center, five 1 m2 (1 m x 1 m) for saplings and seedlings of woody plant species. Within the Nono Sele forest, Rubiaceae, Asteraceae, Fabaceae, Celesteraceae, and Euphorbiaceae, are among the richest plant families in the current study. The vegetation was grouped into three different plant community types. Nono Sele Forest is structurally is highly represented by young sized woody species. The forest is also identified by fair regeneration condition, as demonstrated by the fair density of seedlings as well as saplings for the preponderance of the woody species.

Abstract: Successful conservation and management of chimpanzees (Pan troglodytes) in Yoko Council Forest (YCF), Centre Cameroon, requires reliable estimates of their population size and density, habitat use and threats. Our study offers the opportunity to improve the knowledge on the population density, distribution and threats of the chimpanzee in this area. We used indirect survey methods using nest counts to estimate the decay rate of the nests. This approach consisted of locating and marking fresh nests (less than 48 hours old) at different periods of time and revisiting them at the end of the inventories to verify whether they had deteriorated or not. Human activities, habitat types, and nesting tree species were also assessed. The mean nest decay rate estimated using a logistic regression analysis was 77.53 days with a nest density of 69.3 [95% CI 54.9-86.7] nests/km2, for an estimated population of about 113 [95% CI 45-280] chimpanzees. In YCF, chimpanzees nest in Marantaceae forests and swampy forests, especially on Khaya grandifolia and Uapaca guineensis trees. Transhumance was the greatest threat in the area (75.33%), followed by hunting (13. 66%), wild sawing (8.81%) and fishing (2.2%). These anthropogenic perturbations were most observed in the south-west sector of the YCF. The area with the greatest density of nests occurred at a site least impacted by human activities. It is essential to regulate these activities in order to guarantee the sustainable management of this precious chimpanzee population.
