Description
Summary:Heracleum sosnowskyi Manden.ecological and physiological traits caused it's successful invasion in the taiga zone of the European part of Russia and approach to H. sosnowskyi management were studied. H. sosnowskyi plants metabolism corresponds to the temperature regime. This traits ensures it's adaptation to low temperatures in winter and high growth rates in early spring. The spread of invasion is limited by the requirements of the species to environmental conditions: temperature (growing day degrees), light, moistening regime and richness of the soil. It was shown that the North boundary of the potential secondary H. sosnowskyi range is the interval between the isolines of the growing day degrees (GDD) from 800 to 1 000 С. In the Komi Republic the median cost of H. sosnowskyi plant population eradication was about 35 000 rubles/ha, which is twice as high as that calculated for other territories of the Russian Federation. Systematic work on plant eradication should begin with the implementation of «pilot» projects in the context of a limited budget.
