Biological spectrum of the vegetation of Northeast Haryana in India

Abstract

The present paper deals with the study of the Biological spectrum of the vegetation of North-East Haryana. A detailed study of different life-forms indicated that Nanophanero-phytes (N) and Hemicryptophytes (He) are poorly represented. The study also indicates the presence of therochamaephytic (42%, 22%) flora. The dominance of therophytes might have partly resulted from disturbance in vegetation; due to heavy grazing and exploitation of forests for extensive cultivation. A comparison of the biological spectrum of this area with those of other regions of India reveals that the climate is semi-arid.
