Opis:
Male Opillya (586 km2) is a small part of the Volhyn-Podillya Uplands, located southeast of Lviv and is characterised by the presence of various forms of landscapes, which led to the diversity of its phytobiota. Although located in the neighborhood of Lviv - one of the botanical centers, it was overlooked by botanists in the 19th and 20th centuries. The aim of the study, results of which are presented, was to determine composition of rare and endangered species of Male Opillya’s flora. The article provides a list of these species according to their conservation status defined by the Red book of Ukraine, the list of regionally rare species in Lviv region, the IUCN list, the CITES Appendix №2, and the Bern Convention. Based on the conducted analyses, it can be concluded that 143 species of flora in Male Opillya may disappear due to increasing anthropopressure.

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...
