“…Similar experience was recorded by Oyelowo et al, [12], Onyekwelu et al, [10], Daniel et al [13] The representation of good number of the families by only one or two tree species is similar to other studies in the Savanna area of West Africa [34,35,36]. However, this is an indication of the fragile nature of the savanna ecosystem, which requires attention to avoid extinction of some of these families.…”

The role of sacred forest/sacred groves in the conservation of biodiversity is well recognised and documented. Despite the importance of sacred forests in conservation, data of flora species composition and diversity in many sacred forests still remain scanty. The study was conducted to provide baseline data on tree species composition and diversity of Ipinu-Igede sacred forest with a view to promote the role of sacred forest in flora conservation in the area. Systematic sampling technique was adopted for the study. A base line transect of 2 km long was established and five (5) other transects 2 km long were laid at regular interval of 500 km apart. On each transect, 4 sampling plots of 50 mx50 m were established at a regular interval of 500m apart. Within the 50 m x50 m plots, trees with diameter at breast height (DBH)≥10 cm were identified and enumerated. Species Important Value Index (IVI), species richness, species evenness and species diversity were estimated. A total number of 50 tree species in 19 families were recorded. Cola gigantea was the most important tree species with IVI of 14.56, this was followed by Harungana madagascariensis with 13.14. Caesalpinioideae was the dominant family with 6 species, 48.15% of the families were represented by only one species. The species richness was D=9.436, Species JAERI, 18(3): 1-10, 2019; Article no.JAERI.48054 2 Evenness was E´=0.7668 and species diversity was H=3.646. Thirty percent (30%) of the tree species were in the DBH class of 1-40cm indicating good regeneration status of the sacred forest. Acknowledgement of the traditional practices by scientists and other actors in natural resources conservation will help in promoting forest conservation. Original Research Article

“…Our study findings are in line with the findings of Bhat [37] in the six fresh water swamp forests of Karnataka in India, with H' of 2.53, 3.69, 2.46, 4.04, 3.25 and 4.90. Similarly, in the northern forest-savana ecotone of Ghana [38] obtained H' values of 3.02, 0.04 and 0.39 at near-forest ecotone, near-savana ecotone and mid-ecotone. However, when compared with the findings of Kumar [39] in three sites of tropical dry deciduous forest in western India, where H' values of 0.67 -0.79 were recorded, the H' value of dry deciduous forest (2.96) in PMP is significantly higher.…”

Safeguarding biodiversity is an important component of the REDD+ scheme of the United NationsFramework Convention on Climate Change. Information on tree species and their distribution is therefore needed for successful implementation of forestry carbon projects. Forest inventory data were collected in four natural forests located in Popa Mountain Park, Myanmar. Based on the data from 4-ha sample plots, average stem density ranges from 1293 trees ha −1 in dry dipterocarp forest to 804 tree ha −1 in dry evergreen forest. According to the Jackknife estimator for species richness (trees with DBH ≥ 5 cm), the highest number of species was recorded in dry mixed deciduous forest-74 species ha −1 , and the lowest number of species recorded in dry forest-40 species ha −1 . Dry mixed deciduous forest occupied the highest value on the Shannon-Wiener index and Simpson diversity index while the lowest was in dry forest, indicating that dry mixed deciduous forest is the most complex whereas dry forest is the simplest community. Not only does this study provide useful information on the current status of vegetation type but the information is important for designing forestry management systems that could result in biodiversity conservation and carbon emission reductions.Y.

“…For a good forest conservation plan, understanding tree species composition and knowledge of the forest stand structure is necessary (Farhadi et al 2013). Because trees, an important component of vegetation, must be constantly monitored and managed in order to direct successional processes towards maintaining species and habitat diversity (Attua and Pabi 2013). Variables that influence the tree species diversity are climate, stand structure, species composition, and geomorphology.…”

Almulqu AA, Arpornpong N, Boonyanuphap J. 2018. Tree species composition and structure of dry forest in Mutis Timau Protected Forest Management Unit of East Nusa Tenggara, Indonesia. Biodiversitas 19: 496-503. Plots 10,000 m 2 were established in four sites of Mutis Timau Protected Forest Management Unit (Mutis Timau PFMU), in order to determine tree species density, basal area, importance value index, species richness and to identify the relationship betwen species richness and abundance of trees. A total of 94 species belonging to 72 genera and 45 families were recorded. Species richness and forest structure were different between sites. Moraceae was the dominant tree family at most sites, particulary for Eucalyptus urophylla. The results suggest controlling the number of species, level on species distribution pattern, silvicultural interventions to pioneer species through thinning liberation, seeding and planting (pioneer species) could accelerate the tree regeneration of Mutis Timau PFMU in Kupang District, East Nusa Tenggara Province, Indonesia.
