Abstract: | The present study was undertaken in moist temperate forest of Mandal-Chopta area in the Garhwal region of Uttarakhand, India.
The aim of the present study was to understand the regeneration dynamics of the dominant tree species along an altitudinal
gradient in naturally regenerating, restricted access forest. The overall regeneration status was fairly high in the study
area. Most of the native canopy and undercanopy dominants had frequent reproduction and expanding populations, which suggests
the stability of forest structure/composition and further expansion of dominant species. The overall regeneration of trees
in the forest had a greater contribution of middle and understorey species. Because of infrequent reproduction and declining
populations of some of the dominant native species viz., Abies pindrow, Alnus nepalensis and Betula alnoides, structural/compositional changes in the future are expected in respective forests dominated by them. Abies pindrow and Taxus baccata need immediate attention by forest managers for their survival in the area. Seedlings were found to be more prone to competition
from herb and shrubs than saplings. |
