Marco Neubert, Sylvi Bianchin DETECTING GAPS – GIS-BASED INVENTORY OF ECOLOGICAL NETWORKS IN SELECTED CENTRAL EUROPEAN BORDER REGIONS 2 METHODOLOGY Figure 1: Location of the TransEcoNet study area Dudley and Parish (2006 [4]) define six key steps in a protected area gap analysis. In our gap analysis (figure 2) we followed these key steps but we used easily accessible data on ecosystems (CORINE land cover data set classified through a hemeroby index which we used as a proxy for non-available data on ecosystems respectively biodiversity for the investigation area) as well as worldwide accessible species data (IUCN database). We combined a corridor/habitat approach (identification of existing and potential habitat corridors) with a species occurrence approach (number of threatened species of mammals, birds, reptiles and amphibians) for the prioritisation process [8], [9]. 74

Marco Neubert, Sylvi Bianchin DETECTING GAPS – GIS-BASED INVENTORY OF ECOLOGICAL NETWORKS IN SELECTED CENTRAL EUROPEAN BORDER REGIONS Figure 2: Methodology of the gap analysis [8] In a further step the gaps were overlaid with existing European, national and regional plans for ecological networks. The following datasets were used for the analysis: � European biotope corridors: o European Ecological Network (EECONET) o Pan-European Ecological Network (PEEN) � National biotope corridors: o National Ecological Network (ECONET-POLAND) o EECONET Czech Republic o Territorial System of Ecological Stability (TSES), Czech Republic o Territorial System of Ecological Stability (TSES), Slovakia o Habitat network (Habitatnetzwerk), Austria o National Ecological Network (Nemzeti Ökologiai Halozat, NOH), Hungary � Regional biotope corridors: o Search areas for biotope corridors in Saxony, Germany For Slovenia no network plans were considered because the important ecological areas of Slovenia were already included within the network of protected areas. The gaps and existing plans for biotope corridors and network plans were overlaid and the following five categories were defined: � TransEcoNet gaps corresponding with European, national and regional network plans � TransEcoNet gaps not corresponding with European, national and regional network plans (only TransEcoNet gaps localised) 75
