Ausgewählte Wildtierquerungshilfen über die hochrangige Infrastruktur der ÖBB. Es sind im Viewing Service Wildtierquerungshilfen größer der Kategorie C verfügbar (=Querungsbreite der Bauwerke ist größer als 15 Meter). Bauwerke der Kategorie D und kleiner (>15m Querungsbreite) sind in diesem Viewing Service nicht verfügbar. Die Standorte der Querungsbauwerke stammen aus den GIS Datenbanken der ÖBB INFRA AG und wurden aus einer Kombination aus Vor-Ort Begehungen und der Vermessung via Satellitenbildern kategorisiert. Die Kategorisierung der Bauwerke erfolgte nach FRITZ Völk 2001: WILDQUERUNGSHILFEN ÜBER VERKEHRSTRÄGER – GRUNDLAGEN FÜR DIMENSIONIERUNG UND STANDORTSWAHL IN ÖSTERREICH • Kategorie A (Richtbreite 80 Meter – Mindestbreite 50 Meter) • Kategorie B (Richtbreite 50 Meter – Mindestbreite 30 Meter) • Kategorie C (Richtbreite 25 Meter – Mindestbreite 15 Meter) KEIN DOWNLOAD verfügbar.

In Switzerland, there are 304 wildlife corridors of supra-regional importance (as of 2020). They connect fragmented ecosystems or suitable habitats and are vital for wildlife. This is because roads and railways form insurmountable barriers for many wild animals. Both large wild animals such as deer and stags, medium-sized ones such as foxes and hares, and small ones such as amphibians or bats need to be able to move for food and reproduction. An assessment of wildlife corridors came to the following conclusion: 47 corridors (16%) are largely disrupted and can no longer be used by wildlife; over half (171 corridors, 56%) are significantly to severely impaired; less than a third (86 corridors, 28 %) can be classified as intact. Geodata information: In a first step, the known wildlife corridors were recorded canton by canton from existing data and potential corridors were identified using GIS and divided into wildlife corridors of supraregional, regional and local interest. Subsequently, the main features of the supraregional and regional network system were visualised for the whole of Switzerland. The corridors were then classified as wildlife corridors of supraregional or regional interest according to the importance of the axis on which they lie. The data for the connecting axes and wildlife corridors were recorded and processed in GIS by the Swiss Ornithological Institute Sempach. The supraregional corridors and the connecting axes were updated by the FOEN in 2012 on the basis of information provided by the cantonal hunting administrations.

The specific designation of supra-regional migration corridors for larger, preferably forest-bound wildlife is intended to ensure, improve and, if necessary, restore the functionality of a statewide biotope and habitat network.

LRVA-2022: Evaluation of ecological corridor axes with regard to the permeability of sections of the ecological corridor. On the one hand, the landscape structure is assessed with regard to its permeability (LC structure index) and on the other hand, the landscape elements equipment of the ecological corridor segment (LE equipment index) is considered. The combination of these two indicators results in the combined ecological corridore index, which gives a good overview of ecological corridor areas with low permeability.

Austrian Ecological Corridors - final version. Valued by the experts of the federal provinces. Prepared in the framework of the LE project "Habitat connectivity to safeguard biodiversity in Austria".

In spring 2019, the NP Thayatal GmbH commissioned the Büro für Wildökologie und Forstwirtschaft e.U. (Office for Wildlife Ecology and Forestry) to prepare a wildcat corridor plan in the Wald- & Weinviertel in Austria and the districts of South Bohemia and South Moravia in the Czech Republic as part of the Interreg project MaGICLandscapes. For the study area in Austria and the Czech Republic, the habitat potential of the European wildcat is to be estimated in the form of a habitat model. Based on the habitat model, a corridor analysis will show the possible distribution routes of the cat. As a further step, a strategy and action plan will be developed to provide a basis for improving and expanding migration corridors and thus dispersal opportunities for the wildcat along the green infrastructure. Within the framework of the MaGICLandscapes project, the research results serve as a basis for the planning, construction and management of green infrastructure. For the National Park Thayatal, they serve as input for the further procedure in wildcat management and are taken into account in the wildcat population support concept.

LRVA-2022: Guideline for assessing the permeability of corridors. This guide provides assistance for the assessment of potential disturbance sources and conflicts of objectives within ecological corridors and should subsequently lead to a standardisation of expert assessments in the field of nature conservation. The guide contains the most important definitions, such as the minimum widths of ecological corridors or which objects represent an absolute barrier within a corridor. The guidelines were agreed upon and approved by renowned experts in the field of ecological corridors who have joined together in the Coordination Platform for Ecological Corridors in Austria.

LRVA-2022: Current version of the integral dataset on habitat connectivity in Austria. This dataset takes into account all datasets and designations of habitat corridors from scientific projects and public sector projects (federal provinces). The dataset has been evaluated by the experts of the Cooridnation Platform "Habitat Connectivity Austria" and is updated as soon as new information and designations from projects are available. Further details are available in the endreport: https://docs.umweltbundesamt.at/s/AzZrHid6q9wkDDM
