Dataset for research paper "Heracleum sosnowskyi plants frost-resistance in laboratory and field experiments". 

The Heracleum sosnowsky plants has low freezing tolerance and die in temperature range minus 6–12 °С. Snow cover provides stable soil temperature (not lower than  minus 3 °С) and is the only factor that ensures the survival of H. sosnowsky plants in the regions with cold winter. The H. sosnowsky frost tolerance is higher in autumn (up to minus 12 °С) and became lower at spring (minus 5–7 °С). These results can be explained by absence of deep dormancy in H. sosnowskyi meristem tissues and gradual change of carbohydrate content in them during the cold period. The seeds have high freezing tolerance after its formation but lost it after stratification. The field experiments were carried out by participants of citizen science project “Moroz”. It was shown that H. sosnowskyi plant eradication probability with the help of snow removal completely depends on weather conditions. This method can be used only on the territories where the use of herbicides is prohibited and only in the regions with minimal temperature in January – Febrary not higher than minus 25 °С. The dataset with all measurements made during the experiments is available on the site of “Moroz” project (http://proborshevik.ru).
