The high diversity of woody plant species (WPS) in the Ethiopian Highlands suggests an important role in the livelihoods of the rural poor. However, different property regimes create differences in access and in the biophysical condition of the resources. Our study aims at understanding the biological diversity, ownership regimes, and use patterns of WPS, and developing recommendations for their sustainable management. The study carried out in two villages of North-West Ethiopia. We did exhaustive enumeration and inventory with sample plots to assess biological diversity; and PRA and RRA tools to identify ownership regime, use patterns and desired management. 70 WPS were recorded with decreasing diversity statistics from homestead to church and to communal woodlands. Regarding trees on homesteads under private property regimes, household members define a variety of products, including products with high market value. WPS are therefore managed according to the respective needs of the household. WPS under church property are protected by the strong religious values of the community. Whilst the benefits of protecting these woodlands are non"=tangible, they remain vital to the society. As the protection is a result of guardianship by both priests and members of the parish, it is a hybrid form of private"=public property regime. A variety of different and complex arrangements is in place for the management of WPS on communal woodlands. These are related to proximity of settlement to the area, social institutions in the villages as well as outside interventions by government authorities and development organisations. Benefits for the community thus vary, and range from grazing land to the fulfilment of immediate cash needs in terms of charcoal or timber sale. There is evidence that villagers develop strategies for conservation of communal woodlands dependent on land use history, migration as well their different social realities. We suggest that different property regimes may have substantial impacts on sustainable use of woody plant species. However for successful management both the bio"=physical and the social complexities need serious consideration, in particular regarding common pool resource management.}
