Dynamics of vegetation of Tolbachinsky Dol (Kamchatka) in the last decades
Year: 2013, Issue: LXI, Pages: 119 - 158
The Tolbachic volcano eruption (1975, central Kamchatka) has completely destroyed the vegetation on the area about 100 km2. In subalpine and alpine zones, surviving and colonization of most species are associated with immovable lava substrate, while the tephra deposits inhibit the species colonization and initiate the formation of volcanic desert. The comparison of data obtained in 1995 in the subalpine zone with those obtained in 3—1 years after the eruption has showed that the number of species in this period increased from 48 to 61, Leymus interior and Saussurea pseudo-tilesii were the only species which kept their leading positions, and the mosses density grew up considerably. The list of pioneer species, including their ecological and biological characteristics, is given. The probable scheme of a settlement on volcanic substrates and the succession perspectives are described. The list of vascular plants (263 species) of the area is compiled for the first time.
