Biological Spectrum of Garhwal Siwalik

Abstract

The biological spectrum of Garhwal Siwalik has been studied in relation to the environment. Life forms in the order of importance recorded were therophytes (62.8%), phanerophytes (26.8%), chamaephytes (5.7%), geophytes (4.5%) and hemlcryptophytes (0.2%). The vegetation appears to be predominating by phanerophytes except the river banks and other disturbed areas where therophytes are dominating.
