Abstract

The present state and characteristics of the segetal flora of the Mazowiecki Landscape Park and its buffer zone are described. Flora of the agrocenoses of the Park and its buffer zone is rich and includes 221 species. A _large differentiation of habitats, A wide contact zone with natural communities and traditional methods of cultivation affect its biodiversity. Rare species constitute more than half of the total species recorded in the agrocenoses of the Park and its buffer zone. In total, 25 of them are included in various categories of threat (Zarzycki, Wojewoda, Heinrich 1992). Among the most endangered are such plants, as, Helichrisum arenarium, Aphanes arvensis, Melandrium noctiflorum, Bromus secalinus, Agrostemma githago, Lathytus tuberosus, Kickxia elatine, Centunculus minimus, Hypericum humifusum, Peplis portula, Centaurium pulchellum, Radiola linoides and Myosurus minimus. Apophytes (142 species) prevail over anthropophytes (76 species) in the studied flora. Species of meadow and waterside communities (93 species) predominate among apophytes, whereas in the group of anthropophytes, archaeophytes (59 species) are the most numerous. Analysis of persistence and biological types showed domination of short-lived species over perennials and therophytes over other life forms...
