  • Overview
    What is Eco-Logical?
    Our region
    Eco-Logical Stakeholders
    Eco-Logical Objectives
    Eco-Logical GIS Development
    Regional Eco-Logical Statistics
    Using the Eco-Logical GIS
  • What is Eco-Logical?
    Stems from a national effort by the Federal Highway Administration (FHWA) to integrate infrastructure and eco-system planning
    H-GAC was 1 of 15 agency to receive a grant
    Overall aim is to help advance FHWA’s Eco-Logical goals through local and regional pilot projects
    Goals
    Conservation
    Connectivity
    Predictability
    Transparency
  • 6th Largest Metro Area in U.S.
    Forecasted to have 9.5 Million people by 2040
    Variety of valuable eco-systems
    Tidal Wetlands
    Coastal Prairies
    Forests
    Waterways
    Eco-System Benefits
    Mitigate flooding
    Improve air & water quality
    Wildlife habitat
    Tourism & recreation
    Our Region
  • Eco-Logical Stakeholders
    Eco-Logical Advisory Committee (EAC)
    Multi-disciplinary committee
    Development of metrics and eco-types
    Guided development of a web-based GIS
    EAC included…

  • Eco-Logical Objectives
    Identify top priority areas for conservation
    Develop a metrics system to prioritize environmental resources
    Establish measures by which potential transportation projects may be evaluated
    Early conflict identification
    Regional analysis
    Develop a Regional Decision Support System
    Free GIS based application
    Interactive and web-based (no software necessary)
    Not just an online map, but also analytics
  • Eco-Logical GIS Development
    Development of metrics and GIS data for measuring the intrinsic value of an ecotype
    Eco-Logical GDB
    Ecotype polygon features
    Ecotype classifications
    Calculated metrics for each feature
    Un-weighted score for each feature

  • Eco-Logical GIS Development
    Definition of metrics and calculation
    Size: Area occupied
    Shape: Measure of compactness
    Quality: Beneficial properties of an ecotype feature
    Regional Scarcity: Rarity within the region
    Watershed Scarcity: Rarity within the watershed
    Threatened Species: Presence of threatened species
    Adjacency: Bordering other ecotype features
    Isolation: Degree that an ecotype is separated
    Diversity: Number of different ecotypes within 1 mile
    Scores for each metric were computed on a scale of 0-100 for each ecotype feature
  • Eco-Logical GIS Development
    Ecotype Features & Classification
    Imagery, land cover, and other environmental resource data were used to identify features and classify levels of quality
    Generally focused on areas 100 acres or more in size
    Ecotypes are not mutually exclusive (e.g. Forest with wetland)  Classified based on the greatest coverage for an area
    Coastal Prairie 1
    Coastal Prairie 2
    Coastal Prairie
    Coastal Prairie 3
    Upland Forest 1
    1 = Highest Quality
    2 = Intermediate Quality
    3 = Lowest Quality
    *All tidal wetlands considered high quality

  • Using the Eco-Logical GIS
    Using data in the Eco-Logical database, developed a web-based interactive GIS
    Key Capabilities
    Layers accessible through multiple user interfaces
    Models accessible through multiple user interfaces
    Models can be integrated with other models
    Models and metrics are table driven, thus making updates to the database efficientz
