Abstract: A field-based study of plant diversity in small scope traditional agroecosystem, widely known as homegardens, was carried out in Sabata peri-urban town in the South Western Shewa Zone of Oromia National Regional State, Ethiopia. The study area is categorized as Tepid Humid Mid Highland (H3) Agroecological Zone. In the present study, a total of two hundred forty houses were surveyed within the study area by employing random sampling technique for the presence of home-gardens. Twenty-four of these homegardens were preferentially selected since they were considered manageable for detailed study (data collection and analysis). Data on vegetation (species record, frequency, and number of individuals) were recorded and the collected specimens were identified in the National Herbarium (ETH), Addis Ababa University. Ethnobotanic information was gathered using semi-structured interview, free listing, preference ranking, direct matrix ranking and paired comparisons. Descriptive statistical methods as Shannon-Wiener Diversity Index and Cluster analysis methods were also employed. A total of 135 plant species in 110 genera and 58 families were recorded. Thirty-seven plant species that are distributed among 29 genera and 22 families were documented as food plants. Family Rutaceae is represented by the highest number of food plants (13.51%) followed by Brassicaceae (10.81%). Persea americana Mill., Citrus sinensis (L.) Osb. and Ensete ventricosum (Welw.) Cheesman. were among the most preferred food plants of home-gardens of the area. Twenty four medicinal plants from 22 genera and 17 families were also recorded from home-gardens of the area. Species of the families Asteraceae and Lamiaceae were the most used and each accounted for 16.6% of the total medicinal plants. From this study diverse plant taxa and landraces belonging to various categories of food and non-food crops were identified and recorded which indicate the significance of home-gardening in conserving agrobiodiversity. In addition, the indigenous knowledge used to maintain plant diversity in home-gardens was also carefully considered and documented.
