Meltwater
In this period, the soil is well impregnated with melt water – it is almost ready to put forth the first shoots, and branches will become covered with buds soon. However, alders and willows start to bloom before leaves appear on trees and shrubs in thawed patches of the forest. Different migratory birds return from southern regions – larks, finches, cranes, and wagtails. Cold resistant insects wake up – bees, gnat, mosquitoes, ants, tortoise butterflies.
