Vegetation along the banks of the river differs significantly depending on the surrounding conditions. In the highest part of the course, there is hardly any vegetation except for some grasses, mosses, and lichens. Further down the course of the river, in the Prolock Massive, shrubs and a few lost trees bring more variety to the landscape, although it is still pretty empty.
