Abstract
The forest ground flora plays a vital role in cycling of nutrients, habitat preservation and rejuvenation of shrubs. The vegetation consociated with the forest plays a vital role in the protection, function of the forest ecosystem. Effective management of forest vegetation serves the forest ecosystem in assaying the balance of harmful effects of vying vegetation. Relationship of ecology between environment and vegetation and their ordination techniques and classification methods has become vital means in the research field vegetation ecology. Classification depends on the abundances of ground vegetation species. Multivariate technique is an important technique in ecology and biology for the group prediction. Classification of different plant communities had been accomplished by carrying out TWINSPAN analysis using PC-ORD. The results were shown in a two-way cluster dendrogram. A dendrogram is a hierarchical representation of species in graphical form. The encompassing survey has been conducted in the Changa Manga Forest (CMF) which resulted in the identification of the 45 species belonging to 24 families from all over the forest area. The TWINSPAN results of CMF ascertained the following dominant species in all of the four zones, Cynadon dactylon, Malvestrum cormendalianum, Oxalis corniculata, Parthenium hysterophorus, Desmostachya bipinnata.
