Increase of human population and clearing of forests for their requirements has been alocal as well as global environmental crisis. In Sri Lanka, forest cover has dwindled at analarming rate from 70% in 1990 to 22% as of present. Deforestation and degradation ofland due to many reasons including poverty related land management practices such asshifting cultivation and forest encroachments, conversion of forest estate to other moreeconomically profitable land uses are some of the reasons for the loss of forest. agroforestryhas been identified all over the world as an appropriate alternative which providessustainability According to the Forestry Sector master Plan (1995) the necessity of utilizing the sparsely·used scrub lands for agroforestry ventures to improve the tree cover and socio-economicstatus of the people has been identified. Forest Department too in its Participatory ForestryProject has ventured into establishment of farmers woodlots with the active participation ofcommunities and this programme is wide spread in many parts of the country especially inthe dry zone. However, the composition of these farmers woodlots still not complete toincorporate diversity and sustainability. Therefore, the objective of this present study is toformulate sustainable tree-crop models for a wide range of land classes in the north centraldry zone of Sri Lanka Ipalogama divisional Secretariat in Anuradhapura District was identified for the study.Field studies were done in handsomely selected 3 traditional tank based villages namelySangattewa, Puliyankulama and Dampeleassagama . Information was gathered through aquestionnaire survey, field visits and personnel interviews with villagers. Randomelyselected 44 households or 14.8% of the total households in the 3 villages were subjected tothe survey. The species composition and vertical and horizontal diversity, lightrequirements, multiple uses, financial returns/ha, prevalence of local/indigenous treespecies and farmer's choice were taken into consideration in the formulation of theagroforestry models for the various land classes sampled egoAlluvial plains, middle slopesand upper slopes etc.
