    • 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…
      Galveston Bay Estuary Program Houston-Galveston Area CouncilHarris County Flood Control District Texas Forest ServiceTexas Parks & Wildlife Department Katie Prairie ConservancyUS Fish & Wildlife Service Legacy Land TrustHouston Advanced Research Center Texas A&M GalvestonTexas Sea Grant The Park People The Trust for Public Land The Nature Conservancy
    • 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
      Upland Forest 2
      Upland Forest
      Upland Forest 3

    • 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
