Opis:
The objective for the study is to present the current threats of arable weeds in Poland. The analysis was conducted on the Polish red lists of arable species (3 national and 22 regional and local) prepared in the period 1994-2008. A total of 105 weeds have been considered as weeds threatened in Poland. All regional and local red lists included a joint total of 184 taxa. The particular regions have between 13 and 95 threatened taxa. The species most frequently appearing in the listings are: Agrostemma githago, Bromus secalinus and Camelina microcarpa. Five taxa (Bromus arvensis, Camelina alyssum, C. sativa, Cuscuta epilinum, Spergula arvensis subsp. maxima) are considered extinct on the national scale, while in the individual regions this number ranges from 1 to 15. A relatively high share is allocated on many regional and local red lists to taxa with an indeterminate level of threat. The conducted comparison shows that there is an urgent need to compile similar listings for the remaining areas of Poland, making it possible to create an updated and real listing of threatened weeds. At the same time, it is necessary to update the existing red lists and to adopt more precise quantitative criteria for the threat estimation, in accordance with the estimation parameters introduced by the IUCN and currently in force...

Opis:
Lathyrus aphaca, which is in Poland considered to be an ephemerophyte recorded mainly in the north-west and the south-west, has lately been observed in arable fields in the south of the country. Recent and historical data on the distribution of the taxon in Poland are presented. Original relevés conducted in arable fields in Poland are analysed and compared to those from the Czech Republic, Germany and Slovenia. The current status of L. aphaca in the Polish flora is discussed.

Opis:
Montia linearis is a vascular plant originating from western North America. The expansion of this species has been observed for several decades. For the first time M. linearis was found in Europe in 1989. Further six populations were documented by 2004 within the continent: three in Poland, two in Denmark and one in Hungary. Apart from discovering a new population of M. linearis, we confirmed two out of the three previously known localities of the species in Poland. All the currently known populations of M. linearis occupied predominantly meadow habitats, especially intensively managed sites. Some individuals were also found in disturbed sites with bare soil. The studied species inhabited soils of various types with broad range of fertility as well as humidity. Montia linearis populations reached densities up to 87 individuals per 0.04 m2. The number of seeds produced by an individual was between 10 and 55 in 90% of the studied specimens, however much more fertile specimens were also observed. As the previously presented hypothesis of M. linearis dispersal with rail transport seemed not to be well supported, the connection between the M. linearis presence and cattle husbandry is considered. It is possible that the species can be transferred with living animals or manure. The species was able to survive for at least 26 years within once inhabited site. Further spread of M. linearis within Europe is highly probable. The aim of the study is to: (i) describe the current state of populations of M. linearis in Poland, (ii) provide information on habitat preferences and biology of the species, (iii) assess the invasiveness potential of M. linearis in Poland.
