  1. Monitoring the Impact of Herbicide Application on Invasive and Native Plants in a New Jersey Coastal Dune System Emily Parker and Louise Wootton, Ph.D. Georgian Court University, Lakewood NJ

  2. Carex kobomugi Asiatic Sand Sedge

  3. Native Range of Carex kobomugi

  4. Introduction of Carex kobomugi • Came in to NJ around 1900 • Shipwreck released barrels of Oriental Porcelain packed in Carex kobomugi? • Introduced with ballast?

  5. Spread of Carex kobomugi • Deliberate Planting • Dune stability • Trampling resistance • Disease and fungal resistance • Traffic deterrent • Natural Propagation

  6. Range of Carex kobomugi in North America

  7. Carex invasion of New Jersey’s Coastal Dunes

  8. Dune With Carex

  9. Spraying of IBSP Beds • Targeted application of Roundup® • Narrow nozzle • Intentions: • Remove Carex • Spare remaining plants

  10. Spraying of IBSP Beds

  11. Research Questions • State your research questions here!

  12. Study Site IBSP

  13. Methods • Mapping of bed area • GPS polygons • Diversity Sampling • Systematic sampling design • Count numbers and types of species in 1m2 plots • 1-5% of stand area

  14. Results for Carex kobomugi

  15. Results for American Beach Grass

  16. Results for Golden Rod

  17. Results for Seaside Spurge

  18. Results for Sea Rocket

  19. Conclusions • Summarize your findings here in words • Effect on Carex immediately after spraying? • Effect on Carex in following years? • Effect on native species immediately after spraying? • Effect on native species in following years • This may take more than one slide • Use point form. No whole sentences.

  20. Conclusions • Spray program currently suspended due to cut backs at NJ EPA • Implications for future management if spray program is not restarted?
