    LRVA-2025: 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 As part of the update, the underlying data model was adapted. It is now possible to track all changes made during the update. All updated and valid habitat corridors can be obtained by selecting all edges that have the value “true” in the “valid” data set property. All edges with the value “false” are no longer valid. The reasons for the changes are noted in the ‘comment’ data record property. Most of the changes are so-called “technical changes.” As part of these changes, corridors have been adapted accordingly due to errors in the spatial location of existing crossing structures. The reclassification of corridors is due to new planned or adapted locations of wildlife crossing aids along the existing route. Description of the feature properties see feature catalog: https://geonetwork.lebensraumvernetzung.at/geonetwork/srv/ger/catalog.search#/metadata/e8044763-deb8-43d9-9d51-72b891fe5813 Data set download at: https://docs.umweltbundesamt.at/s/ep9JF44TjYxDY54, also includes QGIS project for direct use of the GPKG file. Two visualizations available. - Corridors classified by corridor category (supra-regional | regional | local) (see Quicklook) - Change layer: Current corridors and all outdated/revised corridor sections

    QGIS Modelle für die Berechnung der Bewertung der Lebensraumkorridore in Österreich. in einem Modell ist der Algorithmus für die Segmentierung des Liniengraphen der Lebensraumkorridore in Österreich verfügbar. Im anderen Modell sind die Algorithmen für die Bewertung der Lebensraumkorridorsegmente hinsichtlich der Ausstattung mit Landschaftselementen, der Durchlässigkeit der Landschafsstruktur und der Gesamtindex der Durchlässigkeit der sich aus den beiden erstgenannten zusammensetzt.

  • 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.

  • 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.

  • Querungsbauwerke entlang der Autobahnen und Schnellstraßen. Im Datensatz beinhaltet sind alle Querungsbauwerke welche eine Bauwerksbreite größer 30 Meter aufweisen (=Kategorie B: Breite die von Wildtieren bei der Querung der Infrastruktur genützt bzw. zur Verfügung steht) und noch eine wildökologische Funktion aufweisen (=durchlässig oder zumindest teildurchlässig sind). Des Weiteren sind vereinzelte Bauwerke der Kategorie C (15-30 Meter) und D (> 15 Meter) im Datensatz berücksichtigt. Diese werden jedoch nur in den Bereichen in denen der integrale Datensatz zur Lebensraumvernetzung in Österreich die Autobahnen und Schnellstraßen quert und kein höherwertiges Querungsbauwerk existiert. Die Querungsbauwerke wurden aus dem Datensatz der im Rahmen der Studie "Kontrollstudie zur Wilddurchlässigkeit auf Autobahnen und Schnellstraßen" aus dem Jahr 2018 erstellt wurde. Dieser wurde in noch einmal visuell kontrolliert. Daten-Download (Geopackage) unter: https://docs.umweltbundesamt.at/s/aKPt5nfeFWJe84q
