	MULTIVARIATE ANALYSIS OF VEGETATION OF CHAPURSAN VALLEY: AN ALPINE MEADOW IN PAKISTAN SULTAN MEHMOOD WAZIR¹, ALTAF AHMAD DASTI², SHEHZADI SAIMA², JEHANDAR SHAH³ AND FARRUKH HUSSAIN⁴ Abstract: Climatically the Chapursan Valley (Gilgit) is classified as alpine region but floristically it may be characterized as a part of Eastern Irano-Turanian region. Presence/absence data were used to classify and ordinate for both sites and species. DCA axes 1 and 2 were used for data interpretation. The relationships between soil characters and DCA axes 1 and 2 were determined using Spearman Rank correlation. Cluster analysis identified 5 vegetation types viz., crassulescent steppes, chamaephytic steppes, erme, moist sub-alpine pastures and riverine pseudo-steppes. These vegetation types have been discussed in the context of topographic and edaphic heterogeneity. 1Department of Botany, University of Science & Technology, Bannu, Pakistan 2Institute of Pure and Applied Biology, Bahauddin Zakariya University, Multan, Pakistan 3University of Malakand, Chakdara, Pakistan 4Department of Botany, University of Peshawar, Pakistan
