Homegarden and coffee agroforestry systems plant species diversity and composition in Yayu Biosphere Reserve, southwest Ethiopia.

Agroforestry systems are among the promising land use systems that enable to address both the development and livelihood issues of the community all over the world. In southwestern Ethiopia, homegarden and coffee agroforestry systems are widely used farming systems. Despite the fact that the systems are widely used and important, there are little studies on the subject. Therefore, the objective of this study was to assess homegarden and coffee agroforestry systems plant diversity and composition in Yayu Biosphere Reserve. To achieve the study's goal, data was collected through forest inventories and household surveys. A total of 101 plant species from 49 families were identified, with 74 from homegardens (37 families) and 57 from coffee agroforestry systems (34 families). In terms of dominating plants in agroforestry systems, home gardens are dominated by herbaceous plants, accounting for 51 percent, whereas coffee agroforestry systems in the study region are dominated by trees, accounting for 72 percent. About 38 percent of household gardens and 77 percent of coffee agroforestry are made up of indigenous plant species. According to the findings, both agroforestry systems at the research site have a great diversity of plant species. As a result, the systems may be able to provide a wide range of services to farmers. Farmers, professionals, and legislators must collaborate to improve the systems' components, composition, and arrangements in order to maximize and protect the systems' multiple benefits.
