Based on case study of some species (Astragalus testiculatus Pall.; Potamogeton sarmaticus Mäemets; Stuckenia filiformis (Pers.) Börner), we considered the origin and absence of need for protection status for locations of rare plant species in the northern part of Western Siberia, outside the natural range. It is shown that organization of special protection measures of rare native species in disturbed habitats is also usually impractical.
