“…Other authors found Conyza canadensis, which was found in the presented study in both farming systems with rather low average abundance of 2 plants per m −2 (organic farming system) and less than 1 plant per m −2 (conventional farming system). This invasive plant species was found by other authors to be one of the most abundant invasive weed species in both agricultural and other ecosystems [43,44].…”

In recent years, the European Union has been paying particular attention to the problem of biodiversity loss. The possibilities of its assessment and conservation are included in the latest European Union (EU) policies and reflected in the European Biodiversity Strategy. The biodiversity of weeds in winter cereals in organic and conventional low-input farms in Eastern Poland was investigated during a 3-year period. Significantly more species and larger abundance were found in organic than in conventional farming systems. The biodiversity of these communities was described by Shannon’s diversity and Simpson’s dominance indices, which showed diversity to be well maintained in both farming systems; however, significantly higher Shannon’s index and significantly lower Simpson’s index values were observed in organic farms. Both farming systems were the mainstay of endangered and rare species, as well as some invasive weed species. Weed communities of organic farms were dominated mostly by Setaria pumila and Elymus repens, while conventional farms were dominated by Juncus bufonius and Setaria pumila. The study showed the importance of organic farming systems for biodiversity conservation. It was also shown that low-input (traditional) conventional farms are also beneficial for biodiversity conservation.

“…In studies on the object, patches with the participation of Echinocystislobata were recorded. In wet habitats with a feature similar to drainage ditches, the authors indicate the appearance of many alien species, e.g., Impatiens glandulifera, Ambrosia artemisiifolia, and Sosnowski's borscht (Heracleum sosnowskyi) (Chmielecki and Kucharski, 2018;Dajdok and Pawlaczyk, 2009;Jackowiak, 1999;Lenda et al, 2019).…”

“…In studies of the communities at the watercourse and the drainage ditches, Echinocystislobata, which is an invasive alien species, was found. Its occurrence outside the natural range may threaten some communities' species diversity (Chmielecki and Kucharski, 2018;Dajdok and Tokarska-Guzik B., 2009;Dajdok and Pawlaczyk, 2009;Dylewski and Maćkowiak, 2014;Lenda et al, 2019;Commission Table 4.

Ditches and drainage canals are an important element in the post-bog meadows. Their basic function is to regulate air-water relations in ecosystems, mainly in agrocenoses. The environmental functions of ditches and canals consist of maintaining a large diversity of flora and fauna species due to high humidity of these ecosystems. The study of plant communities in the ditches in the post-bog meadows habitat of the Supraśl Dolna valley structure in 2010–2020 was carried out. There were 23–27 species of plants in the ditches. Species diversity did not change significantly during this period, while changes in individual species’ coverage and viability were found. The species were classified into two rush communities: reed rush ( Phragmitetum australis) and rush ( Phalaridetum arundinaceae). As a result of the lack of maintenance of the ditches, an invasive species of flapped barbed ( Echinocystis lobata) was found. The natural valorization carried out by the Oświt method showed that plant communities in the drainage ditches are in the lowest valorization classes.

Badaniami objęto florę roślin naczyniowych parku zamkowego w Uniejowie i parku miejskiego im. Żerminy Składkowskiej w Turku. Pierwszy z ogrodów został założony w dolinie Warty, drugi w dolinie niewielkiego cieku o nazwie Folusz. W sezonach wegetacyjnych 2018–2019 przeprowadzono spisy roślin naczyniowych w obu obiektach. Wśród odnotowanych gatunków wydzielono grupy: socjologiczno-ekologiczne, siedliskowe oraz geograficzno-historyczne. Bazując na analizie flory w zakresie spektrum geograficzno-historycznego określono dla badanych obiektów wybrane wskaźniki antropogenicznych zmian. W charakteryzowanych obiektach odnotowano łącznie 314 gatunków roślin naczyniowych. Flora parku zamkowego w Uniejowie obejmuje 217 gatunków, a w parku miejskim im. Żerminy Składkowskiej stwierdzono 202 taksony roślin naczyniowych. We florach badanych ogrodów odnotowano 217 gatunków rodzimych i 97 obcego pochodzenia. Parki są siedliskiem dla takich gatunków jak: Gagea pratensis, Thalictrum flavum, Galium schultesi oraz Corydalis intermedia. Szatę roślinną założenia ogrodowego w Uniejowie charakteryzuje wyższy wskaźnik naturalności flory (25%), niż flory parku w Turku (10,9%). Rezultatem tego są wyższe wskaźniki obrazujące antropogeniczne przemiany obiektu leżącego w Turku. Parki wokół zabytkowych obiektów (zamków, pałaców, dworów) oraz duże parki miejskie stanowią refugia flory naturalnych siedlisk w krajobrazie antropogenicznym.
