Flora segetalna w otulinie Roztoczańskiego Parku Narodowego [The segetal flora in the protective zone of Roztocze National Park]

Abstract

Field studies were carried out using the Braun-Blanquet method (1964) in the years 1995-1999, in 42 localities situated within the protective zone of Roztocze National Park (RNP). Phytoindication photos of cereal crops were taken twice: in spring (spring aspect) and in the first half of July. Photos of root crops were taken only once, at the beginning of September. Segetal flora of the RNP protective zone includes 233 species of vascular plants belonging to 36 botanical families. The most aboundant families are: Asteraceae (23 species), Fabaceae (23 species), Poaceae (21 species), Brassicaceae (16 species), Caryophyllaceae (16 species). In segetal flora of the protective zone, apophytes (57%) out numbered antropophyta. Among apophytes, the largest group consisted of meadots apophytes (30%). In the antropophyta group archeophytes dominated (34%) over epecophytes (6%) and ergasiophygophytes (3%). In segetal flora there was a greater number of annual and biennial species (150 species) than perennial species (83 species).
