      description of cook county volunteer data

      A Master Naturalist is a citizen of the community who shares a passion for the environment and stewardship. They are specially trained in topics such as Natural history of Illinois, Urban Areas and Wildlife, the Art of Interpretation and Teaching, and much more in order to carry out their stewardship of Illinois’ natural resources.

      The rough and tough outdoor work done by our Master Naturalists in restoration include a whole host of activities such as invasive species removal, seed collection, and plantings.

      "When I first began volunteering for stewardship workdays, I selected spots from the Volunteer page on the Forest Preserves of Cook County’s website. My plan was to taste test as many of the North Branch sites as possible and pick a favorite. I have found multiple things that I like about each site, and the stewards and volunteers at each spot are excellent. The work we do is generally dictated by the season, so while I’ve spent a lot of time removing invasive plants, I also got to collect seeds and even plant some new shrubs."

      So much is unknown about our natural world and Master Naturalists are searching to find out. By collecting data on birds, plants, insects, and even rivers, our Master Naturalists are assisting in the discovery of Cook County’s natural ecology.

      "Over the past 6 years with the program we've learned a lot about odonates, from surveying 3 sites, publications, web sites, programs and other monitors. We love sharing our knowledge with others. Keeping watch over odonates helps monitor water quality...our citizen scientist contribution. And the dragon and damsel flies have enriched our lives with beauty and wonder!"
      ~Annette and Dan Pletcher, 2014 Master Naturalists

      "I hosted my first Forest Therapy Walks at Robinson, Caldwell and Thatcher Woods as well as the Chicago Park District’s Portage Park. The Forest Preserves of Cook County has provided a beautiful space for me to bring people together, while honoring ancestral land and bring awareness to this practice. The time I spent in Forest Preserves of Cook County as a U of I Extension Master Naturalist volunteer, laid the foundation for me; supporting my connection to nature as well as improved health, renewed care for the planet and simply falling in love with nature."
