Dolina rzeki Wierzycy - ostoją ginących i zagrożonych gatunków flory segetalnej w regionie Gdańskim

Abstract

The rich vascular flora of the Wierzyca valley also includes plants of segetal communities. Among them are common species, as well as some of the species that are endangered or threatened on a national scale (Warcholińska 1994). The Wierzyca valley provides a refuge for them in the Gdańsk region (Buliński 1993, 1994a). The protection of these plants, preventing, among other things, the use of chemicals in agriculture, may save the rare species of segetal flora from extinction (Buliński 1995).
