Wild taro (Aracaceae family) existence in the forest system or agro-forestry might increase the economic sustainability of forest. Using a Randomized block design method on the 5 plots sample located on the Northern slope of Wonogiri dry-land, the density and distribution type of wild taro and taro-like plants were surveyed. There were six genus of wild tuberous plant with 12 identified species and several endemic species identified.
