Alien vascular plants in the Silesian Upland of Poland: distribution, patterns, impacts and threatsSymptoms of anthropogenic changes in the flora include processes of extinction in some species and spread in others. These tendencies have increased in magnitude in recent centuries, adversely affecting natural biodiversity on a regional, national and continental scale. The main idea behind the project presented here was to investigate the diversity of the alien vascular flora at the regional scale and to update the list of invasive alien species for the Silesian Upland. The aim of this study is also to provide a synthesis of the knowledge accumulated to date on the conditions for their occurrence, their distribution patterns and the possible threat they might pose. The distribution of particular species at the regional scale was investigated by mapping the species on a 2 km x 2 km grid. The study showed that the list of alien plant species for the Silesian Upland encompasses 338 species, including 125 archaeophytes, 195 kenophytes (=neophytes) and 18 species of an uncertain status in the Polish flora. A threat evaluation was performed for particular species on the basis of the number of localities, the diversity of preferred habitats recorded, and their current (over the last decade) tendency to colonise new localities. As a result, a final list of 101 invasive species has been selected. Among the alien plant species considered to be invasive in the area of the Silesian Upland, 20 species are identified as ‘weeds’ (13 archaeophytes and 7 kenophytes), another 25 (exclusively kenophytes), penetrating into natural habitats, are defined as ‘transformers’

The Impact

Today, when anthropogenic pressure on natural ecosystems promotes degradation of natural habitats and facilitates distribution of alien species, local disturbances such as forest management become more significant in relation to alien plant species expansion. The aim of this study was to investigate the impact of forest road and drainage network reconstruction on the vegetation composition focusing on the expansion of invasive alien plant species. The occurrence and coverage of vascular plant and bryophyte species were recorded within 160 sample plots along four forest roads and four drainage ditches. This paper summarises the first results of this study. The main results indicate that small-scale linear corridors like forest roads and drainage networks can promote the expansion of invasive alien plant species.

And Control

Abstract 26 species of invasive alien plant species enter the arable land in Bulgaria as weeds. Some of these species are already causing economic damage and are included in the list of the 100 most economically important weeds. For others, it is only a matter of time before they are included in this list. Possessing a complex of qualities, they spread quickly and aggressively, occupying new areas and settling permanently in them. As artificial habitats in which there is no permanent vegetation, arable land is one of the easiest terrains to invade. The study examines the biological characteristics that determine the invasive nature of this group of plants, their origin, distribution routes, weed crops and control measures that can be taken. Particular attention shall be paid to the additional effects that these species may have on human health, on cultivated crops and on natural habitats located in the neighborhood.

AbstractWoody plant species in recent decades have increasingly often been recorded escaped from cultivation and naturalized. In 2013, a new alien woody species Amorpha fruticosa L. (Fabaceae) was first found in Lithuania. In several Central European countries, A. fruticosa is recognized as invasive species that pose serious threat to natural habitats and ecosystems. To date, A. fruticosa has been registered in three localities in Lithuania: two populations in Ukmergė district and one population in Prienai district. Considering the present state of revealed A. fruticosa populations, it is concluded that this species in Lithuania is already naturalized and potentially invasive. Estimated total area occupied by A. fruticosa in three known localities is about 0.2 ha. In certain areas this species can become abundant and invade significant areas of meadow, forest-edge and other open habitats. Therefore, its immediate control and subsequent eradication can reduce risk of future invasion. Cultivation of A. fruticosa should be forbidden outside the ornamental plantations.

AbstractInvasive plants are non-native, but in most cases naturalised, species that have successfully spread outside of their native range. Aliens invaded all habitats, are competing with native plants, thus, after the direct destruction of habitats, invasions are recognised as the second largest danger for biodiversity. Northern Red Oak is one of the most common invasive tree species dispersed primarily by birds, but new studies have shown that it is also spread continuously in a forest stand. The main aim of our research was to check how strong is the invasion of Northern Red Oak in Silesia Park, where it was introduced together with other alien plant species, and how this invasion interacts with bird diversity. Silesia Park was created 65 years ago on the surface largely ravaged by coal industry. Because many studies indicate birds as vectors of alien plants invasion, we examined the bird fauna in a described area, looking for species that can contribute to spreading oaks. Research showed the diversity of 50 bird species. Surface with a presence of Northern Red Oak was characterised by greater participation of alien plant species than the patch of natural forest, which existed there long before the park creation. The greatest bird diversity was found in the most natural part of Silesia Park, and the lowest in the area of invasion, especially in the case of species classified as “forest birds”. The presence of alien plants increased number of “non-forest” birds, mostly synanthropic species. We also found that Northern Red Oak spreads by spontaneous seed dispersal.
