The area of tropical forest lands in high rainfall areas that is already degraded is great and growing rapidly. Rehabilitation of such lands is important so their biological productivity can support people and reduce pressures for degradation of additional tropical forest lands. While further knowledge and experience is needed, there is a sufficient basis for trial programs. The economic and social well-being is far better served by focusing on rehabilitation of degraded lands than by additional incursions into dwindling stocks of natural forest.
