摘要

Mortality of Sal (Shorea robusta Gaertn.f.) in Barkot Range, Dehra Dun Forest Division (Uttaranchal) mainly affected trees in the diameter class of 20-40 cm. The present comparative vegetational study in the selected sal non-mortality site (NMS) and mortality site (MS) revealed invariably more diverse vegetation in MS than NMS. Mallotusphilippinensis, Ehretia laevis, Miliusa velutina were the major invasive species in the canopy gaps of MS. Further, the altered species composition in the mortality site indicated at drier soil conditions.
