| Research Abstract |
We simulated the effects of change in land use patterns on future species composition within a landscape. Three scenarios were assumed : (1) strictly preserving remnant natural forest, (2) using secondary forests for charcoal production, and (3) the same patterns of land use as it is. It was suggested that the remnant forest will contribute to prevent species extinction, resulting in greater species diversity at a landscape level. Elasticity analyses suggested two types of species: (A) species with greater elasticity of larger trees, and (B) species with greater elasticity of seedlings and saplings. Species of the group A were shown to escape extinction by preserving natural forest of certain area within a landscape. Thus, preservation of natural forests will be effective to maintain species diversity at a landscape level.
