DYNAMICS OF THE VEGETATION COVER REGENERATION OF THE TOLBACHIK AREA
The eruption of the Great Fracture Tolbachik Eruption is one of the most significant phenomena of the XXth century. During that natural ecologic disaster the coverage composed of soil and vegetation was completely annihilated within the area of nearly 500 km2 and some substantial modification of the structure of biocoenosis occured within the area of nearly 300 km2. At the same time the process of mechanic, thermic and chemical damage of vegetation of the Tolbachik Valley resulting from the eruption of the North and South breaches is differentiated according to both its intensity and the range of its influence and the certain mode of influence.No less striking is also the differentiation marked in the character, dinamics and direction of the processes of vegetation coverage regeneration of the damaged sections of the area. For instance, the vegetation of mountainous tundra having occupied practically all the north half of the central and most elevated (800–900 […]
