“…The other populations were represented by the irregular pattern. This result showed a similar trend with other studies in Ethiopia [1,24,34]. Most of the plant population in Asabot mountain forest was in a deficiency of intermediate DBH classes which might be due to selective removal of medium-sized wood plants.…”

Dry Afromontane forests are the most altered and threatened ecosystem. Indeed, having a diverse ecosystem and biodiversity designated as a priority site in conservation. The objective of this study was to demonstrate plant community structure, regeneration status, and conservation priority species. The study was conducted on Asabot mountain forest which is found in West Harare Zone, Oromia National Regional State, Ethiopia. The vegetation sampling was designed at clustered altitude through mixed spatial stratified-random sampling method to ensure a full coverage of environmental variation and habitat heterogeneity. The main parameters used in vegetation characterization was diameter at breast height (DBH), height, seedling, and sapling of wood species recorded at sampled quadrat. The study analyzed plant community indicator species, importance value index, and vegetation structure and regeneration status, and conservation priority of selected species. The plant community was described by 97 species of 90 genera and 52 families. The result showed that eight specific trends and three general trends of population structure based on DBH, seedling, sapling and mature trees or shrubs. The dominant classes of the Asabot dry Afromontane forest were small trees and shrubs which is an indication of secondary vegetation. The conservation priority classification and visual field observations of some woody species were required urgent management intervention. Furthermore, the detail botanical aspects of the forest, the reason for the absence of regeneration in some tree species and socio-economic aspect of the vicinity is strongly recommended farther research in order to inaugurate appropriate management intervention.

“…The patterns of plant species diversity have often been noted for prioritizing conservation activities because they reflect the underlying ecological processes that are important for management (Lovett et al, 2000;Senbeta et al, 2007). Based on similarity index measures, similarity in species composition slightly varied among communities.…”

This study was conducted on Boda Forest in West Showa Zone, Oromia National Regional State, west Ethiopia with the objective of determining the floristic composition, species diversity and the vegetation structure of the woody plant communities in Boda natural forest. Systematic sampling method was used to collect the vegetation data. Accordingly, 60 plots of 20 x 20 m (400 m 2 ) quadrats were laid at every 50 m along five transect lines from south to north direction using compass. Vegetation parameters such as diameter at breast height (DBH), height and density of the study woody species were recorded, and all the collected vascular plant species were brought to National Herbarium of Ethiopia for identification. Vegetation classification was performed using R program Version 2.15.2 software vegan and labdsv packages. The Sorensens's similarity coefficient and Shannon-Wiener diversity index were also used to detect similarities among communities and to compute species diversity and evenness between the plant communities, respectively. A total of 95 species belonging to 76 genera and 58 families were identified from the forest. The collected species were composed of 34.7% trees, 45.2% shrubs, 13.6% liana, 3% epiphyte, 1% trees/shrubs and 1% tree/liana. Five community types, Galiniera saxifrage-Maesa lanceolata, Juniperus procera-Myrsine Africana, Carissa spinarum-Helichrysum citrispinum, Osyris quadripartite-Rhus ruspolii and Acacia abyssinica-Gomphocarpus fruticosus were recognized from the hierarchical cluster analysis. Generally, the forest was dominated by the small sized trees and shrubs indicating that it is in the stage of secondary regeneration. The presence of strong anthropogenic disturbance in the area necessitates the need for an immediate conservation action in order to ensure the sustainable utilization and management of the forest.

“…These different topographic features assisted different types of flora and fauna that have been well adapted to their own geographical features and climatic conditions. According to Fayera Senbeta et al (2007), the climate and topography of Ethiopia vary considerably and appear to have effects on the distribution of biological diversities. Thus, Ethiopia has been considered a country having high biodiversity in Horn of Africa (NBSAP 2005).…”

“…However, due to continuous massive deforestation made on it, the vegetation cover has been reduced through time to what it looks like at the present (Moges et al 2010). Different researchers have studied the vegetation of Ethiopia at different times (White 1983, Friis 1992, Teketay 1992, Bekele 1994, Ayalew 2003, Awas et al 2001, Senbeta 2006, Senbeta et. al.…”

Abstract:This study was conducted on Dirki and Jato sites vegetation in Ilu Gelan district, west Shewa zone of Oromia region, 195 km west of Addis Ababa, to identify floristic composition and plant community types the vegetation. Systematic sampling method was used to collect vegetation data from 54 (20 m × 20 m) plots. To collect data for herbaceous plants, five 1 m × 1 m subplots were laid in each of the main plot, where four were at the corners and one at the center. Cover/abundance values were visually estimated to use for cluster analysis. Shannon -Wiener Diversity Index was used to calculate species diversity, richness and evenness whereas Soresen's Similarity ratio was used to compare the vegetation with other related vegetation. Two hundred and thirteen species were recorded from the sample plots, where Fabaceae, Asteraceae and Poaceae were the most dominant families with 23, 22 and 12 species respectively. Eleven endemic and two near endemic species were recorded from the study area. Based on IUCN Red Data List, nine species were least concern; three were near threatened while one was vulnerable. Three plant community types were recognized from the study area.
