District, East Nusa Tenggara Province. However, some wells in this area need to beÂ conserved by planting of selected species at the watershed area in order the waterÂ available continually during a year. To understand the native and crop species thatÂ suitable to plant conservation the survey at the watershed of â€˜Wetihuâ€™, Baudaok-BeluÂ was conducted in 2008. Aim of survey was to inventory the species and to understandÂ land suitability based on its soil fertility and microclimate condition. Watershed landscapeÂ of â€˜Wetihuâ€™ in Baudaok Village, Belu District are characterized by rolling to hilly altitude,coral reef and limestone of soil material and the low soil fertility. Micro-climate in this
area resulted the marginal land watershed and due to this problem the crop almostÂ can not be planted by the local people. The observation by the distance of 1.5 km fromÂ â€˜Baudaokâ€™ well to the southern was found 39 wild and crop species. Some species whichÂ are able to adapt to the drought ecosystem and has potential to plant as economic cropsÂ are recommended to be selected, i.e.: the main food (Zea mays, Cajanus cajan), fruitsÂ (Musa paradisiaca, Mangifera indica), cattle feeding (Leucaene leucocephala, SesbaniaÂ grandiflora), handmade material (Bambusa sp.), fire wood, wind break trees and cover
crops (Zizyphus mauritiana, Alstonia scholaris, Erythrina orientalis, Gmelina arborea,Schleichera oleosa), perfume oil producer (Santalum album).
