EFFECT OF RECREATIONAL ACTIVITIES ON THE MAIN PLANT COMMUNITIES OF THE TRANS-ILI ALATAU

Svetlana Nesterova

Abstract

Excessive recreational load are altering the composition of plant communities, leading to loss of some native species and replacement their on invasive weed species. Tourism has a particularly strong impact on landscape and biological diversity of mountain territories, in particular Trans-Ili Alatau, which is experiencing increasing anthropogenic pressure on natural ecosystems, because it is located near the largest metropolis of Kazakhstan city Almaty. We have carried out studies on the effect of the recreational activities on the main plant communities of the Trans -Ili Alatau. In some gorges of the Trans-Ili Alatau at different experimental plots was made comparative assessment of disturbance of vegetation communities depending on attendance tourists. The degree of disturbance of plant communities depending on tourist routes and places of leisure was identified On the basis of the data of field research the list of indicator species of plants was compiled and the analyses of their affinity to the plant communities of the study region were carried out. A comparative evaluation of ecosystem disturbance depending on the recreational load was held. The change of plant communities on weedy communities or communities with other dominants with a strong recreational load was observed. The classical methods of floristic, geobotanical research were used. To determine the recreational load, the trial areas method in natural plant communities was used.
