  1. 1. Eco-Logical GIS The development and use of the Eco-Logical GIS for the 8-county Houston-Galveston area October 27, 2010 Bill Bass, GISP Houston-Galveston Area Council Socio-Economic Modeling William.Bass@h-gac.com
  2. 2. 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
  3. 3. 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
  4. 4.  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
  5. 5. 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 Council Harris County Flood Control District Texas Forest Service Texas Parks & Wildlife Department Katie Prairie Conservancy US Fish & Wildlife Service Legacy Land Trust Houston Advanced Research Center Texas A&M Galveston Texas Sea Grant The Park People The Trust for Public Land The Nature Conservancy
  6. 6. 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
  7. 7. 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 GIS/SAS Metrics Model Ecotype Metrics Eco-Logical GDB Eco-Logical Advisory Committee Size Shape Quality Adjacency Regional Scarcity Threatened Species Isolation Diversity Watershed Scarcity Metrics Coastal Prairie Upland Forest Bottomland Forest Tidal Wetlands Ecotype Features
  8. 8. 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
  9. 9. 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 Coastal Prairie 1 Coastal Prairie 2 Coastal Prairie 3 Upland Forest Upland Forest 1 Upland Forest 2 Upland Forest 3 Bottomland Forest Bottomland Forest 1 Bottomland Forest 2 Bottomland Forest 3 1 = Highest Quality 2 = Intermediate Quality 3 = Lowest Quality *All tidal wetlands considered high quality Tidal Wetlands Tidal Wetlands*

  11. 11. 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 ArcGIS Server Eco-Logical Layers Internet ArcGIS Desktop Browser (Flex API) 3rd Party Apps ESRI Base Maps GDBAnalytical Models Un-weighted Weighted iPhone/ IPad ESRI
