AbstractA questionnaire survey was carried out to examine the problems caused by invasive alien species (IAS) in Hungarian protected areas (PAs). Results from 144 PAs were evaluated and compared with a previous study of 21 European countries. In the European survey, the most important threats were habitat loss and fragmentation, Hungarian respondents put IAS in first place. Eradication, control and prevention were mentioned among the best strategies against invasive species in both surveys, but Hungarian PA managers emphasized the efficiency of habitat restoration and regulatory as well. Comparing the harmful animals and plants occurring in most Hungarian and European PAs, we found nearly 30% similarity. In most Hungarian PAs domestic cat (Felis catus Linnaeus, 1758) and black locust (Robinia pseudoacacia L.) were indicated as most harmful species. The results of our study draw the attention to the species, which are highly invasive in Hungary, but are missing from the European PAs list, therefore may pose a potential threat to other protected areas of Europe.

Sandy Sediments

Studies on opencast mines have indicated that the spontaneous colonization of excavations and sedimentation tanks by vegetation is determined not only by the substratum and the land relief, but also by the hydrological and hydrochemical relations in the exploitation hollow. Sometimes, biological invasions can also disturb the natural revegetation. Robinia pseudoacacia L. black locust is an invasive alien species that frequently colonizes sandy habitats. Thirty study plots were randomly established on four types of sites: (1) sandy sediments, extremely dry places located mainly on heaps of post-washer slime; (2) sandy sediments, dry areas that are periodically flooded and have pulp; (3) clay sediments, damp areas that are periodically submerged, and (4) the control, a forest with R. pseudoacacia in its neighborhood. A total of 94 species of vascular plants and seven species of mosses were found. The vegetation at the sites differs and the role of the black locust increases along the dryness gradient and developmental phase of vegetation. Older phases of succession resemble a forest in the surrounding area. It is a R. pseudoacacia species-poor monodominant stand that has been forming for around 30 years. A lack of trees and dense grasses favor the successful invasion of the black locust on man-made sandy habitats.

Urban And Rural Areas

The Lesser bandicoot rat Bandicota bengalensis (Gray and Hardwicke, 1833) is a murid rodent distributed mostly in Asia that can cause substantial negative economic impact in urban and rural areas. Until now, the species has been mostly restricted to the Asian region; and no specimen has been captured or reported as a stowaway arriving to an American port. Here, I report on one specimen captured in Callao’s maritime port, Peru, during sanitary inspection surveillance, identified based on external and cranial characteristics, and similar meristic reported values. This finding shows the potential threat of this species as an invasive alien species and highlights the need for strengthening invasive species protocols on ships.

Abstract The paper presents an inventory and distribution of invasive alien species, in “Iron Gates” Natural Park, especially to highlight their origins, the most aggressive alien species, and their impact on conservation status of habitats, and indirectly their economic and sociological impact on the human communities. This study may have an important role in improving the efficiency of conservation measures, offering valuable information to authorities involved in protected areas administration.

Establishing and managing protected areas (national parks, nature reserves and other sites of conservation value) represent the most common approach to conserving species and ecosystems, but these areas are vulnerable to global environmental change. Recently, Golden Kroner et al. (2019) suggested protected area downgrading, downsizing, and degazettement (PADDD) as one of the main threats to biodiversity conservation. However, there are several other elements, of similar concern, that threaten conservation efforts in protected areas, such as climate change and pollution. Here, in a commentary to the Golden Kroner et al. (2019) paper, we address an additional important element affecting protected area dynamics and robustness that was overlooked by these authors – invasions by alien species. We argue that invasive alien species (IAS) contribute directly to the pressures of biodiversity loss by competing with native species and modifying the characteristics of the invaded ecosystems, and virtually no protected areas are free from these effects. Therefore, excluding IAS from legal instruments and policy frameworks underpinning current conservation approaches in protected areas presents a great risk for nature conservation. Consequently, this aligns poorly with the idea of protected areas being a cornerstone for conservation at local, regional and national levels. For that reason and to paint a more complete picture of the effectiveness of protected areas, we argue that when other factors threatening the existence and functioning of protected areas are discussed, we also need to account for biological invasions. This will ensure that adaptive conservation management strategies protect a wide range of species, ecosystems, and landscapes. Hence, this commentary aims to be of general interest for policymakers, managers and researchers.
