Abstract:

Multivariate technique i.e., CCA has been used to analyze the response of the species against the stress due to moisture. GLM (General Linear Model) response curve and attribute plot using 3-D contour has been used to see the response of the different species in each zone of the Changa Manga forest. Response curve shows that Cynodon dactylon was dominant in two zones i.e., zone-I and zone-III of the forest against moisture stress. Desmostachya bipinnata was dominant in zone-II where as Conyza canadensis was dominant in zone-IV. As Cynodon dactylon was the mostly dominant s in the park the difference in the dominance has been seen in the two zone of park which has been justified by using data attribute plot.
