“…The abundance of IAS and AS (in total 34 alien plant species), especially of invasive alien tree species, in the unmanaged forest habitats investigated for this report is lower than in other European forest habitats (Richardson et al 2007;Chytrý et al 2009;Vilà et al 2011;Nehring et al 2013;Braun et al 2016). Martin et al (2009) conclude that unmanaged forests are actually more resistant to biological invasions, but that the speed of invasion by shade-tolerant species is comparatively lower than in grasslands and other habitats and is therefore often underestimated.…”

“…The IAS and AS identified in both the herbaceous layer and the tree layer are not new to Europe; all of them are commonly known alien species in European temperate forests (Nehring et al 2013;Braun et al 2016;Wagner et al 2017;Campagnaro et al 2018). Most of the 16 IAS occurring in the NFR have a long history of introduction into Austria for ornamental purposes beginning in the 18 th century (Düll and Kutzelnigg 2005;Fischer 2008;Universität Innsbruck 2019).…”

Invasive alien plant species (IAS) are one of the greatest threats to global biodiversity and the sustainable functioning of ecosystems and mitigating the threat posed by them is therefore of great importance. This study presents the results of a 15-year investigation into how IAS occur within natural forest reserves (NFR): unmanaged forest ecosystems within Austria, concluding that unmanaged forests are not resistant to plant invasions. The study comprised ground vegetation, regeneration, and stand structure surveys. The presence or absence of IAS in different forest types was assessed and the influencing variables for their presence or absence were determined. In addition, the study analysed whether the abundance of IAS has increased at the site level within the past decade. Significant differences in the probability of IAS presences between forest types (photosociological alliances) were found. The results of the study show that natural riparian and floodplain forests are among the forest types most vulnerable to biological invasions, which is reflected in elevation and soil type being determined as the main factors influencing the spread of IAS in unmanaged forests. The results of this study may be useful for persons responsible for sustainable forest management programmes or for managing forested areas within national parks. They provide a case study on non-intervention forest management policy in order to mitigate the impacts of IAS in protected areas. Forest areas, where IAS begin to spread can be identified, which in turn leads to measures in the early stages of invasion, and to optimise monitoring and control measures for relevant species in Central European forest types.

“…The data collected for the needs of our survey do not confirm the occurrence of the following species that have been indicated as threatening the local diversity of freshwater habitats in the CBR in Poland: Cabomba caroliniana, Eichhornia crassipes, Elodea nuttallii, Hydrocotyle ranunculoides, and Myriophyllum heterophyllum (Rodríguez-Merinoa et al 2018). However, the following species were identified in the littoral zone of the habitats studied, which, in Poland, the Czech Republic (Vardarman et al 2018), and in central European protected areas (Braun et al 2016) pose a significant threat to the conservation of biological diversity: Fallopia spp., Heracleum mantegazzianum, Impatiens glandulifera, and Solidago spp. Interestingly, some researchers (Rodríguez-Merinoa et al 2018) have reported that non-native species are more common in anthropogenic environments than native species.…”

In this paper, we discuss the threats to freshwater habitats that are highly important to the European Community in the Continental Biogeographical Region of Europe, specifically in Poland. The study covers nine freshwater habitat types distinguished in Natura 2000, Annex I of the Habitats Directive, which is a network of nature protection areas in the territory: standing water bodies (3110, 3130, 3140, 3150, and 3160) and running water (3260, 3220, 3240, and 3270), occurring in 806 Special Areas of Conservation in Poland. Of the 72,673 km 2 total area of freshwater habitat covered by Natura 2000 in Poland, only 25.70% was classified, from the period 2006-2018, as favourable status, whereas 68.72% was classified as unfavourable inadequate or unfavourable bad status. Based on a multivariate analysis, we found that significant differences in the conservation status of freshwater habitats resulted from a variety of threats, pressures, and activities, among which the most significant are urbanization and residential and commercial development; transportation and service corridors; decreased and unstable water resources; fishing and harvesting of aquatic resources; agricultural pollution; improper management and use of the agricultural catchment and forest catchment; changes in biocenotic evolution, invasive species succession, and more intense touristic exploration. The changes in conservation status of habitats 3110, 3130, 3140, 3160, and 3260 are also associated with climate change. Taking into account the threats identified, a list of recommended practices for the freshwater habitat types is presented, to be considered in habitat conservation programmes.

“…The spread of alien plant species makes it difficult to achieve the basic objectives of protected areas, i.e. the protection of biodiversity [PYŠEK et al, 2013;BRAUN et al, 2016]. Obviously, due to their high degree of naturalness the protected areas are more resistant to invasions by alien species than anthropogenically transformed lands [BYERS, 2002;PYŠEK et al, 2003].…”

Studies aimed at the identification of the range and the ways of spread of invasive alien plants in the Kampinos National Park (KNP) outskirts were carried out between 2012 and mid 2018. Special emphasis was placed on surveying the sites of the invasive species and diagnosing potential threats posed to the natural and semi-natural vegetation of the national park by them in rural areas. A floristic survey was carried out on the majority (93 localities) of settlement areas in the vicinity of KNP, in its buffer zone, frequently near the border of the park. Thirty-nine invasive taxa were found which may potentially pose a threat to the ecosystems of KNP. The most frequently identified species included trees and shrubs: Acer negundo, Rhus typhina, Robinia pseudoacacia, Partenocissuss inserta, and herbaceous plants: Conyza canadensis, Erigeron annuus, Solidago serotinoides, S. canadensis. Species encroaching from the settlement areas to semi-natural and natural communities include Bidens frondosa, Echinocystis lobata, Impatiens glandulifera, I. parviflora, Juncus tenuis, Lupinus polyphyllus, Reynoutria japonica, R. xbohemica and Solidago serotinoides. Most of them are species from the highest (III and IV) classes of invasiveness in Poland. The close distance to the Warsaw conurbation, and the road network developed around KNP has certainly affected the number of alien species recorded in the analysed area. Urbanized lands neighbouring the Park are still probably a source from where alien plants disperse to the protected area.
