Presentation Transcript

  1. Riverine Analysis Northern Great Plains Sarah Olimb NPCN Fall Meeting 20 September 2013

  2. Aquatic Ecosystem Classification • Watersheds • Local climate • Basin morphometry • Drainage boundaries • Physiography • Regional Climate • Physiography • General physiognomy of vegetation

  3. Analysis Goal: Identify riverine conservation priority areas based on representation (species and habitat richness) and ecological condition (derived from Human Threats Index)

  4. Index of Species Representation and Ecological Condition Rescaled the Species Richness Index and Ecological Condition Index using linear interpolation to, respectively, 0 to 10 and -10 to 0 scales Resulting layer shows range from High quality (high richness/good ecological condition) to Low quality (low richness/poor ecological condition)

  5. Representation of Habitat Types Used Aquatic Ecological System (AES) types (ecological “neighborhoods”) Sensitivity analysis to explore the interaction between the PRAI and the number of AES types

  6. Appendix

  7. Expert Reviews • The Nature Conservancy Aquatic Ecologists • WWF Conservation Ecology, Freshwater Aquatics team • Montana State University Dept. of Ecology
