Riverine Analysis

This analysis aims to identify critical riverine conservation areas in the Northern Great Plains based on species and habitat richness and ecological condition. Using indices derived from a Human Threats Index and rescaled measures of species richness, we classify aquatic ecosystems into high and low-quality categories. The study encompasses watershed characteristics, local climate, basin morphometry, and regional physiography, with input from aquatic ecologists and conservation experts. The results inform effective conservation strategies for vulnerable aquatic habitats.

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
