Temporal changes in Oak forests over last three decades in western Himalaya, India

The distribution and dynamics of forest resources provide basis for management and conservation planning. Long-term data and information is important to improve our understanding on spatial and temporal variations of a particular ecosystem. In view of this, distribution and dynamics of temperate for...
