The conservation value of small, isolated fragments of lowland tropical rain forest

Deforestation is occurring at an alarming rate in the lowland tropics. In many tropical regions, rain forest is restricted to small (<100 ha), isolated fragments. While only the preservation of large areas of tropical rain forest can safeguard the complete biota, recent research has shown that a substantial number of forest species can persist for decades in fragmented forest, though large vertebrates are susceptible to habitat fragmentation. Inevitably, small fragments will become the last refuges of many rainforest species that are on the brink of extinction. In areas with little rain forest remaining, fragments can be the 'seeds' from which to re-establish extensive forest.
