Desarrollo sostenible: la visión desde los países menos industrializados; memoria
Current rates of deforestation in the Central American region are among the highest in the world. Removal of forest cover for agriculture and alternative land-uses results in forest fragmentation and isolation of tree populations, as well as the depletion of genetic variation. Similarly, selective logging may result in genetic erosion by continual removal of the preferred genotypes. Together, these processes have profound implications for the conservation and sustainable management of forest genetic resources. A number of recent studies have indicated that extensive genetic variation exists both within and between populations of Central American tree species. Results of such studies may be used to assess the impact of deforestation and selective logging on genetic resources, and also have implications for genetic conservation in national parks and forest reserves. An integrated programme of conservation and use of forest genetic resources is urgently required in Central America, involving greater regional collaboration in research and development, and the participation of local communities. Such initiatives are essential if Central American forests are to be managed as a sustainable resource in the future.

| Summary: | Current rates of deforestation in the Central American region are among the highest in the world. Removal of forest cover for agriculture and alternative land-uses results in forest fragmentation and isolation of tree populations, as well as the depletion of genetic variation. Similarly, selective logging may result in genetic erosion by continual removal of the preferred genotypes. Together, these processes have profound implications for the conservation and sustainable management of forest genetic resources. A number of recent studies have indicated that extensive genetic variation exists both within and between populations of Central American tree species. Results of such studies may be used to assess the impact of deforestation and selective logging on genetic resources, and also have implications for genetic conservation in national parks and forest reserves. An integrated programme of conservation and use of forest genetic resources is urgently required in Central America, involving greater regional collaboration in research and development, and the participation of local communities.
