The association Salicetum triandrae is dominated by Salix triandra or S. viminalis. Frequently found but with a lower cover are also S. euxina and S. purpurea. Although S. euxina is potentially tree, it is often shrubby or low-growing in this vegetation due to frequent disturbances by the current. This vegetation occurs on loamy or sandy sediments along rivers from lowlands to the altitudes of about 450 m. The original composition of the herb layer has been strongly altered due to the spread of invasive neophytes.
