Abstract
The study of ordination by mean of Hierarchical cluster analysis (HCA) and Detrended Correspondence Analysis (DCA), among communities was carried out in spring, summer and winter that comprising 22 communities in each seasons. The Hierarchical Cluster Analysis shows that in spring, relationship among communities were jointed into 21 cluster cycling where in cycle 1 it shows the relation of 2 communities at 1.0928E+03 and last i.e. cycle 21, 22 communities were connected with one another at 1.0144E+05 with 3.29 % chaining. In summer, communities were combined into 21 cluster cycling where in cycle 1, it shows the relationship of 2 communities at 4.6423E-02 and last i.e. cycle 21, 22 communities are connected with each other, at 3.9256E+00 with 0.66 % chaining. In winter, communities were united in a single faction into 21 cluster’s cycling wherever in 1st cycle, it illustrates the relationship of 2 communities at 1.0792E-01 and in final cycle, 22 communities were related with one another at 6.5113E+00 by way of 2.63 % chaining. In spring and winter the DCA give 4 factions while in summer, 5 factions were originated at EIG 0.495, 0.495 and 0.385 respectively on DCA Axis 1. Classification and ordination techniques provided very corresponding results originated on plant life capacity.
