Share of endangered and invasive species in field communities on the example of Maciejowice commune.

Abstract

The share of endangered and invasive species in field communities was presented in the paper. Floristic studies were carried out between 2010 and 2013 in agricultural cultivations of the Maciejowice commune. A rich flora of this area consists of 216 species and includes 21 taxa belonging to various categories of threat. Another 15 species are considered invasive in the area of cultivated fields. Such species as Kickxia elatine, Camelina sativa and Valerianella rimosa are very rare. They are also seriously endangered in Poland. A high share of invasive species in agri-cultural cultivations of the studied area is bothering. Such species as Echinochloa crus-galli, Galinsoga parviflora and Setaria pumila were noted very commonly, with a large cover-abundance, whereas Veronica persica, Amaranthus retroflexus, and Avena fatua were recorded less commonly. In the poorest soil-agricultural complexes, in winter cereals, a mass occurrence of Anthoxanthum aristatum was noted. Their number repeatedly affected the structure and floristic composition of communities.
