Treść
Invasion by alien species (AS) is one of the most serious threats to ecosystems. InEurope, the Natura 2000 habitats network was established to protect habitats vital forthe conservation of biodiversity and function of ecosystems. Therefore, the appearanceof AS in Natura 2000 habitats is a warning signal that the most valuable Europeanhabitats may be endangered. However, quantitative studies encompassing a widespectrum of habitats are lacking, and there is no insight into the differences in the levelof invasion among habitats. Our survey is based on the State Monitoring of Natura2000 data and aimed at an assessment of the level of invasion in natural habitat typesin Poland. The percentage of invaded locations, number and frequency of alien plantspecies was assessed in 79 Natura 2000 habitats, both terrestrial and water, investigatedon 5,941 locations. The most invaded habitats (with the highest percentage of invadedplots) were dunes withHippophaë rhamnoides(habitat code 2160), rivers with muddybanks (habitat code 3270), and alpine rivers and herbaceous and ligneous vegetationalong their banks (habitat codes: 3220, 3230, 3240). Grassland, forest and most of thebog, mire and fen habitats and also some habitats on a rock were invaded by a relativelylarge number of AS, but their frequency was comparatively low. In contrast, a highfrequency of AS was found in the majority of dune and costal habitats and calaminariangrasslands. Compared with the period 2000–2010, the number of AS in some riparian,grassland and forest habitats rose noticeably. The occurrence of AS showed a negativecorrelation with conservation status of the habitats. This study has demonstrated thatstandard monitoring of Natura 2000 habitats provides the basis for the detection of AS,including invasive ones, in all types of habitats, and can be used for development rapidand effective response programs.
