Presentation To Julie Edwards Class

  1. 1. Invasive species, Volunteerism, and Habitat Restoration (or, how we rocked the hemlock)
  2. 2. Introduction - terms <ul><li>Biodiversity Native plant </li></ul><ul><li>Co-evolution Habitat </li></ul><ul><li>Monoculture Restoration </li></ul><ul><li>Preservation Ecosystem </li></ul><ul><li>Control treatment </li></ul><ul><li>GPS (Global Positioning System) </li></ul><ul><li>Statistical Significance </li></ul>
  3. 3. Invasive plants <ul><li>Introduced by people. </li></ul><ul><li>Did not co-evolve with landscape. </li></ul><ul><li>Many native plants in US suffered similar fates as Native Americans. </li></ul>
  4. 4. <ul><li>HIPPO </li></ul><ul><ul><li>H = Habitat Loss and Fragmentation </li></ul></ul><ul><ul><li>I = Invasive Plants </li></ul></ul><ul><ul><li>P = Pollution </li></ul></ul><ul><ul><li>P = Population (human overpopulation) </li></ul></ul><ul><ul><li>O = Overconsumption </li></ul></ul><ul><li>Estimated to cost the US over $137 billion a year. </li></ul>Invasive Plants (contd.)
  5. 5. Poison Hemlock ( Conium maculatum) <ul><li>Introduced from Europe as a garden plant. </li></ul><ul><li>Highly toxic! </li></ul><ul><li>Apiaciae (carrot) family, formerly Umbelliferae. </li></ul>
  6. 6. Species biology <ul><li>Can grow 3-10 feet in one year. </li></ul><ul><li>Allelopathy </li></ul><ul><li>Density – 595 plants in ½ M² </li></ul><ul><li>Grows in shady, moist areas. </li></ul><ul><li>Produces between 5,000 and 38,000 seeds per plant. </li></ul>
  7. 7. Santa Clara County <ul><li>Naturally high biodiversity. </li></ul><ul><li>Increasing urbanization. </li></ul><ul><li>Great possibilities for volunteerism. </li></ul>
  8. 8. Study premise <ul><li>Hand-pull and re-seed with native plants with similar species biology. </li></ul><ul><ul><li>Blue Wild Rye – Native California bunchgrass, perennial. </li></ul></ul><ul><ul><li>Yarrow- mid-summer seed, grows near hemlock. </li></ul></ul><ul><ul><li>Hayfield tarweed – late summer seed, forms dense stands. </li></ul></ul>
  9. 10. Volunteers <ul><li>61 million people a year in US. </li></ul><ul><li>Measham and Barnett, 2007 </li></ul><ul><li>1. Helping a cause </li></ul><ul><li>2. Social interaction </li></ul><ul><li>3. Improving skills </li></ul><ul><li>4. Learning about the environment </li></ul><ul><li>5. General desire to care for the environment </li></ul><ul><li>6. Desire to care for a particular place </li></ul>
  10. 11. Curriculum development <ul><li>Used games, acronyms, and audience participation. </li></ul><ul><li>Balanced social time with working. </li></ul><ul><li>Focused on biocultural diversity and teams. </li></ul>
  11. 12. Biocultural diversity <ul><li>Bio – life + Culture + Diverse = Difference </li></ul><ul><li>Preservation of indigenous and diverse cultures = preservation of biological diversity. </li></ul><ul><li>Just as an ecosystem is strengthened by its biological diversity, a community or team is strong when different people know and can do different things. </li></ul>
  12. 15. Study site <ul><li>Acterra Stewardship Program at Arastradero Preserve in Palo Alto. </li></ul><ul><li>622 acres supports 334 species. </li></ul><ul><li>Large, educated volunteer base –1000 a year. </li></ul>
  13. 17. Research design <ul><li>49 ½ M² quadrats. </li></ul><ul><li>Pull, pull and re-plant, control. </li></ul><ul><li>Monitored for 15 months. </li></ul>
  14. 18. Results January, 2007 Pre-treatment March, 2008 15 months after treatment
  15. 19. 4 months after treatment <ul><li>1 = control </li></ul><ul><li>2 = pull </li></ul><ul><li>3 = pull and re-seed </li></ul>
  16. 20. One year after treatment <ul><li>1 = control </li></ul><ul><li>2 = pull </li></ul><ul><li>3 = pull and re-seed </li></ul>
  17. 21. 15 months after treatment <ul><li>1 = control </li></ul><ul><li>2 = pull </li></ul><ul><li>3 = pull and re-seed </li></ul>
  18. 22. Recommendations <ul><li>Install live plants instead of sowing seeds </li></ul><ul><li>Larger plot size </li></ul><ul><li>Different plant selection (more shade-loving, rhizomonous) </li></ul><ul><li>Measure / quantify results from volunteer education </li></ul><ul><li>Track volunteer time for economic analysis. </li></ul>
  19. 23. Questions, Comments, Quiz
  20. 24. Taxonomy <ul><li>Species name vs. common name? </li></ul><ul><li>King Phillip could only find good spaghetti. </li></ul><ul><ul><li>1. Kingdom 2. Phyllum </li></ul></ul><ul><ul><li>3. Class 4. Order </li></ul></ul><ul><ul><li>5. Family 6. Genus </li></ul></ul><ul><ul><li>7. Species </li></ul></ul>
  21. 25. Taxonomic classification <ul><li>Kingdom – Animalia </li></ul><ul><li>Phylum – Chordata </li></ul><ul><li>Class – Mammalia </li></ul><ul><li>Order – Carnivora </li></ul><ul><li>Family – Felidae </li></ul><ul><li>Genus – Felis </li></ul><ul><li>Species – Felis catus </li></ul>The Littlest Leopard – Felis catus showing her intelligence.
  22. 26. Dichotomous key <ul><li>Two-part questions, which allow you to progress through a species’ characteristics to figure out what it is. </li></ul><ul><li>Used to classify plants, animals, rocks, etc. </li></ul><ul><li>Example: </li></ul><ul><ul><li>Does the animal have legs? </li></ul></ul><ul><ul><li>If yes, does the animal have fur? </li></ul></ul><ul><ul><li>If no, does the animal live in water? </li></ul></ul>
