摘要：The Homegardens are one of the most important niche in which farmers feel confident to plant
and maintain tree and shrub species. Homegardens floristic composition in western Harerghe in general
and Habro district have not been given much research attention. The study investigated the floristic
composition of the homegarden agroforestry system in 36 homegardens. The study was carried out in
Habro district at three sites (Melka Belo, Haro Chercher and Lega Bera) Kebeles. A total of 77 plant
species were recorded from homegardens of the study area. The families Fabaceae, Solanaceae and
Euphorbiaceae were the most diverse, each having nine, seven and five species. The most abundant
woody species in the study area were Catha edulis, Coffea arabica and Cordia africana where as the
most abundant herbaceous species were Lycopersicon esculentum, Capriscum spp and Nicotina
tabacum. The highest species richness (40 woody and 19 herbaceous) was recorded at Haro Chercher
site for both woody and herbaceous species and lowest number of species was recorded at Melka Belo.
According to Jaccard’s and Sørensen’s similarity indices Melka Belo and Haro Chercher Homegardens
Agroforestry System (69.23 and 81.82) were the most similar pairs followed by Melka Belo and Lega
Bera (61.54 and 76.19) while Haro Chercher and Lega Bera (52.70 and 69.03) were the most dissimilar
pairs. Hence, the research encourages agroforestry systems that are found to have positive effects on
plant diversity.
