Natural values of the Wda River valley near Świecie

Abstract

River valleys hold great natural value. They constitute important ecological corridors, through which various species of plants and animals can migrate. The river along with the adjoining wet meadows and forests are places of great biodiversity. River valleys in our country, especially the Wda valley, have not been thus far thoroughly studied. This paper aims to discusses the flora of the part of the Wda valley between the villages of Kozłowo and Wyrwa. At this short distance (2.3 km) up to 496 species of vascular plants were found, of which 12 are under legal protection and another 40 are threatened and regionally endangered.
