Transcript

  • 1. Iowa NatureMapping: Road Kill Monitoring Project Jason O’Brien, M.S. Iowa State University Extension Wildlife Programs
  • 2. Iowa NatureMapping: Road Kill Monitoring Project Thank you to the Living Roadway Trust Fund of Iowa for completely funding this project and all the NatureMapping volunteers who contributed to this project!
  • 3. What is NatureMapping? • A Citizen Science Program • Monitor wildlife species • Trained citizen volunteers • Standard set of protocols, of which the basic idea is…
  • 4. Tell us what you see… Jeff LeClere Jeff LeClere
  • 5. …And where you see it
  • 6. NatureMapping Training Workshop • Level I: Basic wildlife ID  Map reading  Geo-referencing  Sampling methods &  Data-entry  • Mammals • Reptiles • Amphibians • Birds
  • 7. Early planning stages of a road kill study… while promising, we scrapped this idea in favor of a more tested approach.
  • 8. Living Roadway Trust Fund Road Kill Study • Use trained NatureMapping volunteers, using basic NatureMapping wildlife monitoring protocols, to answer a question for the Iowa Department of Transportation.
  • 9. LRTF Road Kill Study • Roadside Prairie Planting Assumption:  Enhances Roadside Habitat
  • 10. LRTF Road Kill Study • The Questions:  Do the roadsides provide good wildlife habitat? or  do they “siphon” off species only to have them killed on the roadway?
  • 11. Methods • Preliminary Survey to test NatureMapping as a sampling method • Used pre-existing NatureMapping Protocols
  • 12. Methods • Volunteers picked 1 or more roadsides they travel often (1, 2, or 5 mile segments) • Monitor as often as they can or whenever they see road kill
  • 13. Methods • Roadside vegetation documented using NatureMapping Habitat Codes (i.e. Cool Season Grass –  brome, KY Bluegrass; Tallgrass prairie; Woody Fencerow; etc.) Entered as Habitat type  (up to 6 different habitats, beginning with most abundant) in data form
  • 14. Methods • Adjacent habitats described in “Comments” section of data form  Riparian corridors, waterways, forest, wetlands, fencerows intersecting roadways, etc.
  • 15. Results
  • 16. Wildlife species most reported on Road Kill Survey
  • 17. Most Common Roadside Habitats – red bars are mostly agricultural; least reported is prairie
  • 18. Wildlife species most reported and the habitats in which they were found
  • 19. Aerial view of some road kill study sites – note the different kinds of habitat adjacent to roadways
  • 20. Conclusions • Top road kill species typical of most roads in Iowa • Roadside habitat typical of most roads • Prairie roadsides under represented!
  • 21. Conclusions • Course Dataset – not fine enough to detect an effect from Roadside vegetation • However, data seems to indicate that adjacent habitat greatly impacts wildlife
  • 22. Round Two: What we would do differently • Results Indicate need to fine-tune protocols
  • 23. Round Two: What we would do differently • Assign Roadsides: Control for:  Prairie roadsides  Non-prairie roadsides  Length & Width  Adjacent Habitat  Type of Roadway
  • 24. Round Two: What we would do differently • Control for Time of Year Set definite sampling  timeframes
  • 25. Round Two: What we would do differently • Develop specific data entry forms for this project…
  • 26. Round Two: What we would do differently …Integrating newest mapping technology with data submission and retrieval
  • 27. Iowa NatureMapping GIS Mapping Tool Currently in test phase: • Will be making available in 2008.
  • 28. Contact Jason P. O’Brien, M.S. Coordinator Iowa State University Dept. of NREM 339 Science II Ames, IA 50011-3221 515/294-6440 jpobrien@iastate.edu www.extension.iastate.edu/naturemapping
