摘要：The study was conducted in four districts, namely Nansebo, Harenna Buluk, Dolo Mena and Dodolla, Southeastern Ethiopia with the following objectives - to: (i) investigate species richness and similarity, diversity, evenness and stand structure of the woody species; (ii) determine the amount of carbon stock stored in the above-ground biomass of woody species; (iii) establish the relationship between the Shannon diversity indices and carbon stock, (iv) identify the most important forest non-carbon benefits obtained by the local communities from the forests; and (v) determine contribution of forest resources to the local economy when compared with other incomes generated from agriculture, including livestock. Data generated by FARM Africa were used to achieve objectives (i) - (iii). To achieve objectives (iv) and (v), a focus group discussion and household survey were conducted. A total of 125 species of woody species, representing at least 45 families and 77 genera, were recorded. The Shannon diversity and evenness indices of the woody species ranged between 2.8 (Dodolla) and 3.5 (Harenna Buluk) and 0.79 (Nansebo) to 0.82 (Dolo Mena), respectively. The woody species had densities ranging from 550 (Dodolla) to 2106 (Harena Buluk) individuals ha-1. The above-ground carbon stock stored ranged between 148.88 (Dodolla) and 246.27 (Dolo Mena) tons ha-1. About 10 products and services were mentioned by the respondents as important non-carbon benefits from the forests. The non-carbon benefit with the highest contributions in the three districts was fuelwood, while coffee had the highest contribution in Dolo Mena. The contribution of forests to the local economy was significantly compared with other incomes. Forests contributed 40.2% to the household income in Harenna Buluk District and 18.8% in Nansebo District. Considering non-carbon benefits in the design and implementation of reducing emissions from deforestation and forest degradation (REDD+) is important to ensure its acceptance by local communities.
