Abstract. Lake Tana basin is one of the most important watersheds of Nile basin. It is of great importance for the economy and politics of Ethiopia. In past decades, natural vegetation of Lake Tana basin was heavily destroyed for continuous expansion of cropland. Vegetation conservation and restoration have to be performed in order to protect natural environment and maintain the biodiversity in Lake Tana basin. To provide detailed information of actual vegetation for planning of vegetation conservation and restoration, in this research we mapped the vegetation of Lake Tana basin based on high spatial resolution images provided by Google earth and field survey data, through the approach of visual interpretation. A total of 31972 polygons were generated to represent the vegetation patches of Lake Tana basin on the map, and the validation based on surveyed vegetation plots indicated that 90.6 % patches were correctly identified. The statistics of vegetation map indicated that natural vegetation (natural forest, woodland, bush land, grassland and wetland) occupies 14.32 % of the basin area, plantation forest occupies 1.92 % of the basin area, cultivated land occupies 61.8 % of the basin area, water body, village and urban occupy 20.8 %, 0.68 % and 0.46 % of the total area of Lake Tana basin respectively. Doi of the dataset used for map production is doi:10.4121/uuid:48d45053-36f6-411b- 96b1-7ae0e22d56d0. We expected that this vegetation map could benefit vegetation conservation and restoration in Lake Tana basin.
