Other Site Characteristics

The regulated Gerje-patak (Gerje Stream) is at numerous places flanked by causeways and grasslands along the interfluve areas with the other water-courses. Bog patches, Molinia meadows, fen meadows and alkaline grasslands variegated with brookside willow and Salix cinerea as well as Alnus stands in the upper course are characteristic. In the sandy grasslands, Populus canescens forests can be found. The enclosed arable lands and older uncultivated lands are relatively frequent on the site. Along the Besnyo-csatorna (Besnyo Canal) extensive alkaline plains and lakebeds are located. By the former peat digging sites next to the Kis-Gerje (Kis-Gerje Stream) a tussock and a Sphagnum sp. patch are present.
