Abstract

The research has been conducted at HYANAN forests located at five kilometers, north east of ILAM. To assess the probable forest structural changes during the past fourty years. A 0.2 hectars plot area was suggested in accordance with minimal area approach. sample plots were located systematically with a 100 meters intervals. Then data collection were completed according to this scheme. Using spss software, comparisons were made, between the past and present forest condition. Interpretation of the data, suggests that major structural changes have occured during the past 40 years, both from qualitative and quantitative point of view, leading to what is called, forest degradation. As a general framework, low rate of volume increment, grazing, human intervention, charcoal preparation, forest fire, parasit plants, were the major factors, affecting the structural changes of the studied forests. Finally, guidelines are suggested for optimum manipulation of the forests.
