Abstract

While habitat destruction always causes species extinctions, the rateof extinction may be highest in those habitats which become the most fragmented as they decline in size. For this reason, knowledge about the patterns and origins of rain forest fragmentation in the tropics may prove useful in efforts to preserve biodiversity. This paper calculates the degree of fragmentation in the tropical rain forests of 51 nations containing 83 per cent of the world's tropical forests. By these measures, West Africa and Central America have the most fragmented tropical rain forests in the world. Not surprisingly, rain forests in theAmazon basin are the world's least fragmented. Some patterns of tropical deforestation appear to produce more fragmentation than others. A two-stage least squares analysis of these data suggest that deforestation driven by smallholders is most likely to produce highly fragmentedforest habitats. The implications of these findings for policy and for further research are briefly discussed.
