Outline of Final Research Achievements

This study aimed at evaluating the sustainability of selective logging in tropical seasonal forests of Cambodia and Myanmar. We found that damage from felling, skidding and road construction were one of the lowest levels in Myanmar and Cambodia, compared with reduced impact logging in other countries. However, heavily degraded condition was found in the stand being subject to higher frequently logging in recent years, than the rule of 30 year cutting cycle. We conclude that selection systems themselves of these two countries do not cause forest degradation, but practices beyond allowable limits of the rules result in heavily degraded forests with subsequent illegal logging.
