  17. 18. Volunteers! <ul><li>Backbone of Acterra’s Stewardship Program at Pearson-Arastradero Preserve. </li></ul><ul><li>Community service, interns, corporations, individuals. </li></ul><ul><li>Adopt-a-plot, workdays, weed warriors, logistics. </li></ul><ul><li>Avg. 750 people/yr with 4,000 hours donated! </li></ul>
  18. 19. What you can do <ul><li>WEED ABATEMENT </li></ul><ul><li>Contact city and county governments and transportation agencies and ask them to control weeds like Dittrichia and Italian Thistle on rights-of-way, roadside areas, and public lands. </li></ul><ul><li>NATIVE PLANTS </li></ul><ul><li>Advocate and practice the use of native plants for landscaping where you live, play, work, shop, visit, and recreate. </li></ul><ul><li>RECREATE RESPONSIBLY </li></ul><ul><li>Stay on trails! Learn about native ecosystems and the dangers to them. Don't be a weed-seed or Sudden Oak Death source; clean boots, clothes, pets, tires, and vehicles whenever you go from one park or preserve to another. Leave no trace! This includes microtrash (i.e. orange peels) as well as garbage. </li></ul>
  19. 20. Wait, there’s more! <ul><li>CARBON REDUCTION </li></ul><ul><li>Carpool, bike ride, and take public transportation whenever possible. Purchase carbon credits when you can't. Buy local foods and products. Visit www.acterra.org for more ideas. </li></ul><ul><li>VOLUNTEER AND DONATE! </li></ul><ul><li>Participate in habitat restoration, trail maintenance, bird-box monitoring, weed eradication, and public education and outreach. If you don't have time to volunteer, make a donation to your favorite park or preserve on a regular basis. </li></ul><ul><li>HABITAT RESTORATION </li></ul><ul><li>Acterra hosts habitat restoration events every second and fourth Saturday from 9-1, as well as Wednesday evenings from 6-8 PM. For information on what to wear, what to bring with you, and directions to the Preserve please see: http:// www.acterra.org/arastradero/volunteer.html . </li></ul>
