1. Digital Wetlands of Southwestern Pennsylvania Presenter:Samuel M. Zehel Jr. California University of PA Wetlands are a sparse but important feature of a complex southwest Pennsylvania topography. The region’s historic coal industry, agriculture and more recent urban expansion and the resulting ecological effects from these activities make information on natural systems such as wetlands and associated drainage systems increasingly important.

2. Long-term Goal Provide a unique, interactive digital database and web- mapping service within a geographic information system for public utilization of mapping data for wetland status, function, and associated resource vulnerability assessment.

3. User Wishes Searchable Readable Accessible Reliable Expandable Informative

Wetland Assessment Level 1 REMOTE SENSING DATA NO SITE VISIT Level 2 RAPID ASSESSMENT SITE VISIT WITH HABITAT, FUNCTION, & STRESSOR CHECKLISTS Level 3 FUNCTIONAL OR BIOLOGICAL ASSESSMENTS DETAILED QUANTITATIVE CHEMICAL, AND/OR PHYSICAL, AND/OR BIOLOGICAL DATA COLLECTION Field Survey Data Collection Design

8. Purpose & Function Assessment tool primarily developed as a tool for performing regulatory categorization of wetlands by Ohio EPA For our study: modified from Ohio Rapid Assessment Method (ORAM) Focus is on overall wetland condition and ecological integrity; indirectly function

9. Parts of RAM 5 main parts of RAM:  BACKGROUND INFORMATION SECTION  SCORING BOUNDARY SECTION  NARRATIVE RATING QUESTIONS  QUANTITATIVE RATING QUESTIONS  CATEGORIZATION WORKSHEET

10. Wetland Assessment Metrics Disturbance metrics  buffer width, intensity of surrounding land use, hydrologic, substrate, and habitat intactness Other metrics  Size, water source, hydroperiod, connectivity, habitat development, special wetland communities (e.g., bog, old growth), plant community quality, microtopography, habitat heterogeneity, amphibian habitat

14. Fulfilling User Needs By combining public data with field survey data, we hope to provide the user community with a tool that can be used to compare/contrast wetlands conditions from the past, and into the future.

15. Time/Cost Analysis Public dataVS.Private data Advantages Price/AvailabilityTimely EstablishedSpecific Disadvantages MundaneCostly GeneralNiche data

16. Strengths and Advantages Recent & accurate field data using rapid assessment site visit with habitat, function, & stressor checklists More detailed information on habitats than other surveys of the area Several layers available to compare Ease & availability of use.

17. Next Steps of Action Provide wetland metrics in descriptive as well as numeric representation Improve/update field survey metadata Include map search by city & street address as well as name (currently only wetland available) Improve speed & reliability of mapping app. Increase & improve data content (more surveys) Represent wetland by polygon instead of point.

18. Show where plant communities are located in polygon form (not points) Next Steps(cont.)
