Woody and non-woody tree/shrub species conservation is one of the ecosystem services provided by agroforestry (AF) systems across the agricultural landscapes. The study was aimed to investigate plant species diversity, structure, and composition of three AF systems. Twenty farms were randomly selected, and vegetation inventory was employed in a 10×10 m farm plot. A total of 52 perennial woody and enset species belonging to 30 families were recorded. Of all species identified, 63.5% were native and two species were registered as endemic. The highest proportion of native species was recorded in Enset based (93.3%) and the least was in Coffee-Fruit tree-Enset based (59%). According to IUCN Red Lists and local criteria, 13 species were recorded as of interest for conservation in all AF systems. Prunus africana was identified as both vulnerable by IUCN Red Lists and rare for 25% of species that least occurred. In terms of diversity and richness Coffee-Fruit tree-Enset based AF systems were significantly different from the two remaining systems. However, the species abundance and evenness did not show significant difference. In general, owning higher number of species under AF systems of the present study showed a good potential to serve as a heaven for biodiversity conservation.
