The managem~nt of agrobiodiversity (AB) by farmers buttresses sustainable food security and continuous ecosystem services against the predicted future global environmental change. However, the loss of traditional knowledge on local landraces. and breeds, inadequate information on AB distribution, and the focus on improved varieties are becoming threats for the long-term conservation of AB. The current study focuses on agrobiodiversity of enset- based agricultural landscape of KT, southern Ethiopia. The agroclimate of the areas was used for selecting a total of 12 study sites (farmscapes). To understand the roles of the socio-economic conditions on AB, 180 households (HHs) were selected based on the wealt~ status. Environmental data such as slope and elevation were recorded for each sampling sites. The area share of the crop as well as woody species was measured, and the species were inventoried. Standard ethnobotanical methods were used to collect information on the uses of these plant species. The data analyses were carried out by Cr4NOCO for Windows ver. 4.52, R program 2.14.0, Minitab ver 15, and SAS ver. 8.02. A total of 371 plant species were recorded whereby crop ' are 92 and woody pecie are 186. A total of 170 medicinal plant species that are helpful in the primary health care of the human and the livestock are reported. Seventeen plant species endemic to Ethiopia were identified, of which thirteen are medicinal plants. Years of farming, livestock holding, and distance to market influenced the number of crop species significantly. There are 111 landraces of enset (Ensete ventricosum) recorded from the study area. The number of landraces increases with increase in the farmland size and the elevation. The slope, age of farmland, area of the woodlot, and available HH labour influence the woody species richness. One exotic tree species, Eucalyptus camaldulensis was identified as the most important woody species. Finally, it is recommendable to train extension agents on the areas of AB maintenance so that they would assist farmers effectively. Moreover, avoiding extensive plaptation of Eucalyptus on crop fields may contribute to the long-term persistence of AB of the study area.
