Associations of macrophytic vegetation in Kashmir Lakes

  • D. P. Zutshi
Article

Summary

The macrophytic vegetation of 15 Kashmir lakes has been studied by the floristic-sociological method. 26 associations and 3 subassociations in 6 classes, 8 orders and 16 alliances have been recognised, of which 3 alliances, 18 associations and 2 subassociations are described for the first time. The provisional character of the syntaxa is emphasised. An account of the lake conditions and climate is given. The greatest diversity of communities is found in the Anchar lake and the smallest in the Ahansar lake. Differences in diversity are supposed to be correlated with differences in nutrient status and amount of wave action. Kashmir lakes come close to thePotamogeton type of Fosbergs classification.

Zusammenfassung

Die Makrophytenvegetation von 15 Gebirgsseen in Kashmir (1587–1600 m) wurde floristisch-soziologisch analysiert. Es wurden 26 Assoziationen und 3 Subassoziationen in 6 Klassen, 8 Ordnungen und 16 Verbänden unterschieden, davon 3 Verbände, 18 Assoziationen und 2 Subassoziationen neu für die Wissenschaft. Der vorläufige Charakter dieser Syntaxa wird betont. Es wird berichtet über die physisch-chemischen Verhältnisse der Seen und das Klima. Die größte Diversität an Gesellschaften wird im Anchar See, die kleinste im Ahansar See angetroffen. Unterschiede in der Diversität werden mit Unterschieden in Nährstoffversorgung und Beweglichkeit des Wassers korreliert. Die Seen von Kashmir sind demPotamogeton-Typus der Klassifikation Fosbergs ähnlich.
