The resistance of a number of indigenous species of shrubs and subshrubs of Sakhalin to a low-snow winter

Abstract

A negative reaction to the anomalous nature of the low-snow winter of 2018/19 was shown by representatives of 78% of the species of shrubs and subshrubs indigenous to Sakhalin island, studied in the botanical garden of the city of Yuzhno-Sakhalinsk, and 9% of species of foreign shrubs. Such a reaction of local plants can be associated with their adaptations to such factors as a thick snow cover, temperature stability in spruce-fir forests, weak soil freezing. The latter may be due to deep snow, high groundwater levels, or if the species is adapted to the warmer climate of the main part of the range.
