Abstract

In Ethiopia forest resources are decreasing at alarming rate. Agroforestry practice such as homegarden play an important role for the conservation of woody species and also improving human wellbeing. Although homegardens are known to substantially contribute various benefits to households, there is lack of quantitative information on the benefits of homegardens in the study area. Therefore the aim of the study was to assess woody species diversity, management practices of woody species of the study area. The study was conducted in Heban Arsi wereda, Oromia, Ethiopia. A total of 99 households were randomly selected for questionnaire survey to gather information on farmers’ strategy of managing woody species diversity in homegarden. Vegetation data was collected from homegarden of 54 randomly selected households. Systematic sampling technique was used to collect vegetation data from nested thirty 20m X 20m sample in the adjacent natural forest. Sampling plots were placed at every 100 m interval along the transect lines at 150m apart. Woody species > 5 cm diameter at breast height were measured and recorded. All woody species with dbh < 5cm were counted and recorded. The vegetation data from the homegarden was collected from 20m x 20m plot size. A total of 73, 58 homegarden and 48 in natural forest woody plant species belonging to 35 families were recorded from homegardens and the adjacent natural forest in the study area. The dominant families which contributed to the overall species richness in both land uses were Fabaceae and Rutaceae. The total number of woody species in the homegardens and the natural forest was 58 and 48 respectively. Natural forest showed higher diversity (H’ = 2.28) than homegarden (H’ = 1.98). The similarity in woody species composition between homegardens and adjacent natural forest was 62.5%. Afrocarpus falcatus and Croton macrostachyus are the most important woody species among the woody species common to both homegarden and adjacent natural forest. To sustain the management of all woody species, farmers carry out management practices such as pruning, thinning, composting, weeding, hoeing and watering. Finally, this study indicated that homegarden agroforestry play a vital role in conservation of biodiversity. Community of the study area should be strongly encouraged and capacity building to further conserves woody species should be done.
