The article presents the results of a biomorphological analysis of 51 species of the genus Salix L. in the western part of Baikal Siberia. The species were assigned to 10 biomorphs belonging to four main groups (tree, tree-shrub, shrub and dwarf shrub). Using a digital elevation model, elevation parameters were determined for all occurrence records. The distribution of species across three elevation complexes was revealed: elevated plain, low-mountain and mid-mountain. It was found that with increasing of absolute altitude, larger biomorphs are replaced by smaller ones, reflecting the adaptation of species to
high-mountain conditions.
