Zur Erfassung der Flächeninanspruchnahme und Versiegelung wurde von Bund, Ländern, Städten und Gemeinden das ÖROK-Monitoringmodell entwickelt und fachlich abgestimmt. Als Ergebnisse liegen seit 2025 wesentlich verbesserte, robuste Daten zur Flächeninanspruchnahme für Siedlungs- und Verkehrszwecke, Freizeit- und Erholungs-, Ver- und Entsorgungszwecke und Energieflächen, sowie Versiegelung und Baulandreserven vor. Diese Arbeiten sind Teil des laufenden österreichweiten operativen Monitorings, welches im Rahmen der ÖROK abgestimmt und vom Umweltbundesamt im Auftrag der ÖROK berechnet wird. Alle relevanten und regelmäßig aktualisierten öffentlichen Verwaltungsdaten von Bund und Ländern zur Bodenbedeckung und Landnutzung werden mit einbezogen und durch einen integrativen, räumlich expliziten Ansatz zusammengeführt. Gesamterhebungen werden aufgrund der Aktualisierungsintervalle der Datengrundlagen in einem drei-jährigen Zyklus durchgeführt. Aufgrund der Überlagerung unterschiedlicher Datensätze enthalten die Daten nach wie vor viele Splitterpolygone. Eine topologische Überarbeitung bzw. kartographische Generalisierung wurde nicht durchgeführt, da die primäre Verwendung des Datensatzes die statistische Auswertung ist.

The project contributes significantly to a successful and long-term implementa-tion and safeguarding of habitat connectivity in Austria. In addition to the net-working function of habitat corridors, the aspect of how habitat corridors can also be used or adapted for the protection and improvement of insect diversity in Austria was addressed for the first time. Work package 1 is dedicated to the analysis of habitat features and landscape structures with regard to their qualitative (diversity) and quantitative (abun-dance) suitability for insects. The extrapolation of the results of work package 1 implemented in work pack-age 2 provides a first area-wide overview of the structural connectivity of habi-tat corridors in Austria and their suitability for the dispersal and protection of insect diversity. Work package 3 is dedicated to the development of a guideline for assessing the permeability of existing habitat corridors. With the definition of the most important indicators for the assessment of planned measures within the corri-dors, a standardised set of rules for nature conservation assessments is availa-ble for the first time, on which the leading experts in the field of habitat connec-tivity have agreed. Awareness-raising measures are an essential prerequisite for achieving the broadest possible acceptance of habitat connectivity among regional actors (e.g. farmers and landowners). This is the focus of work package 4. For a sustainable protection of the habitat corridors, it is essential to make the habitat corridors visible in an official national document. This issue is addressed in work package 5 by the implementation of a process that allows a widely auto-mated production of specific maps on the topic of habitat connectivity embed-ded in the Austrian forest development plan. A further milestone is the establishment of the “Coordination Platform for Habi-tat Connectivity in Austria” in work package 6, which consists of the most im-portant experts in the field of habitat connectivity in Austria. The objectives of the coordination platform are the regular exchange of experience, a unified and coherent representation of the actors in habitat connectivity and the promotion of the protection of habitat corridors in Austria.

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

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: 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.
