Rate of recovery of lichen-dominated tundra vegetation after overgrazing at the Yamal Peninsula ( Short Communication )
Lichens are the most sensitive part of vegetation cover to reindeer grazing. In this study we analyse success of restoration rate of lichen-rich tundra vegetation after ceasing the grazing stress at the Yamal Peninsula. On experimental plots we compare the main parameters of lichen mat (species dive...
