1 Econnect Restoring the web of Life Developing a tool to analyze the potential ecological connectivity in the Alps The Joint Ecological Connectivity Analysis and Mapping Initiative (JECAMI) and the ECONNECT GeoPortal

2 Aim Where is the ecological continuum (the corridors and barriers) in the pilot aeas and how can they be estimated and compared over all pilot regions? WP4 - Data Management (GIS platform) WP5 - Barriers and corridors (Analysis of species and habitat types) WP7 - Implementation in Pilot areas Connectivity mapping and landscape modeling Identification of connectivity potential

3 Mapping relevant factors CSI The landscape approach Structural Connectivity SMA The species approach Functional Connectivity CARL The network approach Structural and functional c. JECAMI: Joint Ecological Continuum Analysis and Mapping Initiative A platform to analyze and visualize ecological connectivity in the Alps

4 Objectives of the landscape approach General definition of the structure of an ecological continuum/ the connectivity Defining suitable criteria for an assessment of the space Definition of the scale: Provide global, alpine-wide analysis (>100 km 2 ) as well as local analysis(<1 km 2 ) in the municipalities high spatial precision and resolution of data is appreciated Mapping on the web - broad access for all interested parties without specific and expensive software

5 Locally high precision data needed

6 10 Indicators Population Landuse Landuse Planning Altitude and Topography Fragmentation Infrastructure Landscape Heterogenity Edge density International Protected Areas Ecological Measures

7 Data processing 7 Pilot regions Many Political regions A few Coordinate systems A bunch of Datasets 1 Coordinate system 10 Indicators (raster datasets)

8 Data Management GIS data collected included: - Built-up areas, settlement areas - Administrative boundaries - Road and rail infrastructure (classified) - Dams, weirs - Terrain information - Ski areas, cable cars, lifts, overhead power lines, fences, embankments

9 Data Management GIS data collected cont d: - Land Use/Land cover - Land Use planning - Forest Development Plan - Protected areas (classified) - River network, lakes, river morphology, embankments, hydro power stations, discharge, abstraction, watersheds,

10 Data Management - Sources for each data set: five alpine countries, three languages, 18 regional Administrations - Harmonised in language, classifications, coordinate systems - Plenty of data requires a data structure - Metadata and license documentation - Online GeoPortal set up for easily sharing data and having one central repository

12 Population Definition: General human pressure on environment population k = Ai site _ density i Refinement based on spatial disaggregation i Population Distribution by factor k. k describes population the & relation tourist data between site density and population density depending on the ratio of residential classes. Realisation: classified residential areas Indicator Value: population & tourist activities = population + ovn ImpFct 365 population & overnights per hectare pop.dens. per hectare = k *site _ density i 05/10/2011 CSI - Workshop, Bolzano 4th/5th Slide n 12

13 C Fragmentation Definition: degree of fragmentation of natural & semi natural spaces Realisation: = Indicator value: classification based on effective mesh size (m eff ) M eff is the area of a regular barrier grid geometry of the same meeting probability of animals calculated for each part of the natural living settlement space of areas a fragmented (incl. industrial area. & commercial) Calculation of an facilities interpolated (airports, surface railway areas) unfragmented Area road system railway system pressure lines n 2 dams i= 1 A A i g fences and walls m eff = 1 A g n i= 1 A i A g : total area A i : subarea i n: number of subareas interpolated surface 05/10/2011 CSI - Workshop, Bolzano 4th/5th Slide n 13

21 Species Map Application

22 Conclusion Strengths +++ Scalability and flexibility Access Open technology Extensibility Weakness --- Assessments (ecosystem value?) based on expert opinions Just a few indicators, no time dynamic data Data acquisition and data preparation is time-consuming

23 Wordwide connectivity?
