Some effects of selective logging on forest productivity and ecologyf ecological forest functions to hardly noticeable interventions. The paper based on field data and hypothesis allows the conclusion that selective logging only under special conditions can be regarded as a sustainable form of land use.

By the year 2050, half of the surface covered by tropical forests in 1990 may have been converted. In the years ahead, a greater proportion of tropical lands may be expected to support secondary forest, degrade

Biological characters and plasticity of juvenile tree stages to restore degraded tropical foreststs and their valuable slow growing timber species. Most attempts to encourage natural regeneration after intensive logging have failed because of the elevated maintenance costs for the remaining standing trees, and the difficulties in obtaining high rates of survival for the young plants.
