N. M. Kovaleva, G. A. Ivanova, E. A. Kukavskaya Restoration of the Ground Cover after Surface Fires in Pine Forests of Middle Taiga // Forest Science (Lesovedenie). 2011. No 5. С.30-35. The influence of experimental surface fires of different intensity on the ground cover was investigated in pine forests of the middle taiga. Fires, irrelative of their intensity, are shown to decrease the projective coverage and mass of dominant dwarf shrubs (Vaccinium vitis-idaea and V. myrtillus). The structure of postfire plant microgroups is determined by their boundaries before the fire and the degree of burning-out of the litter. Mosses and lichens fully disappear after fires of any intensity. On the 8th year after the fires, the projective coverage of mosses (Pleurozium schreberi and Dicranum polysetum) was 4-6% as compared to their coverage (50%) before the fires. On the areas burned out to the mineral soil horizon, pioneer mosses (Polytrichum and P. commune) predominate. The lichen cover is not regenerated. Pine forests, forest fires, fire intensity, microgoups, succesion, phytomass. |
