Later on, logging became officially prohibited in primary forests, in areas over 1000 meters in elevation and in areas with slopes of 50% or more (Guiang, 2001). Today, large no of forests covered by various logging arrangements, such as Timber License Agreement, Integrated Forest Management Agreement, and Socialized Industrial Forest Management Agreement.
