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.

First of all, a GIS model was created, which aims to use a least-cost path algorithm to determine the general course of the corridors as precisely and in as much detail as possible. This is particularly necessary because the area under investigation, at more than 30,000km², covers more than a third of the total size of Austria - and thus could not be processed in a justifiable time frame on an expert basis alone. In a next step, the results of the GIS model will be used as a basis for further expert work. This offers the possibility to additionally take into account local particularities as well as findings from workshops, etc. This way, a result can be elaborated that can be used as a basis for the development of the GIS model. In this way, a result can be developed that is spatially accurate even at a scale of 1 : 10,000 - and not only in the bottlenecks. - ConNat-AT as Shapefile:ConNat-AT-KorrEngstKern-UTM-N33.zip Zip -File: complete dataset of all narrows, corridors and core areas in Austria (Esri Shapefile, EPSG 25833 (UTM N33, ETRS 1989)).

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.

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

LRVA-2022: Generated standard map representation of the special topic maps for ecological corridors in Austria for the forest development plan. The maps are automatically updated as soon as the data basis (=modification of ecological corridors or modification forest mask from the Federal Forest Research Centre /BFW) changes. Details see also end report available: https://docs.umweltbundesamt.at/s/AzZrHid6q9wkDDM. QGIS-Modell for the maps generation available here: https://docs.umweltbundesamt.at/s/CjTNNLzPEKbNWyX
