“…With rapid growth, eucalyptus is important to suck up carbon dioxide from the atmosphere and return oxygen to the atmosphere (Tadesse and Tafere, 2017). Hence, with the growing interest in tree planting for climate change mitigation, it has a great role to neutralize the effect of greenhouse gases responsible for global warming (Mersha et al, 2022). However, Eucalyptus has negative environmental impacts due to the lack of a proper plantation management system (Yitaferu et al, 2013;Daba, 2016).…”
A woodlot is a piece of woodland that is a privately owned farm for tree plantation. It has become a common activity among local households in Ethiopia. Currently, local households in Jamma District, Ethiopia predominantly plant eucalyptus woodlot as their alternative income source. However, there is no empirical evidence on the factors that affect driving maximum income from Eucalyptus woodlot. This study investigated the factors affecting income from Eucalyptus woodlots in the Jamma district. Data were collected and organized by the household survey, key informant interview, field observation, and focus group discussion. Qualitative and quantitative data were used from primary and secondary sources. A total of 150 randomly selected households were interviewed from Eucalyptus woodlot owners. Multiple linear regression analysis was applied to determine the significant variables affecting the income amount derived from eucalyptus woodlot. The results described the socioeconomic characteristics of households, and investigate the determinants of Eucalyptus woodlot income level. Age, family size, distance from the market, and household experience are the major factors that determine the income of households derived from Eucalyptus woodlot production. Household income derived from eucalyptus woodlot was negatively and significantly affected by the distance where their woodland was located from the market and their experience in planting Eucalyptus as the regression analysis showed. The result of this study suggests that technical manuals should be implemented to minimize its negative impacts on the environment to made the households better benefited from their Eucalyptus woodlot products and for sustainable production.

“…The geology of the study site is characterized by nithosols soil types in the northwestern, southwestern, northern, and central parts of the district. In some midland parts of the district, there is black soil that displays cracks and sticky characteristics during dry and wet seasons, respectively and soils that are found in lowland areas are gray, red, and whitish which are shallow and extremely stony [ 12 ].

Background
Dry evergreen montane forests of Ethiopia provide economic and ecological services for the community but it is under several threats of natural and anthropogenic disturbances. The study aimed to investigate the floristic composition, species diversity, and plant community distribution of Guard forest along environmental gradients.
Methods
A systematic sampling technique was used to collect vegetation and environmental data. Fifty eight plots each with 400 m2 (20 m X 20 m) were established for trees and shrubs and 2 m x2m (4 m2) for herbs along eleven transect lines. Shannon Weiner diversity index and evenness were used to assess the species diversity and richness. The similarities among plant communities were computed using Sorenson’s similarity index. The plant community types and vegetation-environment relationships were analyzed using hierarchical cluster analysis and Canonical correspondence analysis (CCA) in R software, respectively.
Results
A total of 137 plant species belonging to 111 genera and 55 families were identified. The most dominant families in the study area were Fabaceae and Asteraceae. Among the total plant species documented in the forest, 42(30.65%) were trees, 36 (26.28%) were shrubs, 48(35.04%) were herbs, and 11 (8.03%) were climbers. Of the total species, 14(10.22%) species are endemic to Ethiopia and Eritrea. Three plant community types were identified by cluster analysis. The Shannon-Weiner Diversity Index was 3.39 and evenness was 0.87 for the forest. The pattern of plant species distribution was significantly influenced by altitude, pH, BD, slope, and charcoal (P < 0.05).
Conclusion
Guard forest has good species diversity and richness, and supports different endemic plant species that show the potential of the area to support useful but some of the characteristics species are not found in the forest and others are rare in their existence due to the presence of disturbances and need immediate conservation to ensure sustainable use and management of the forest.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
