  • Become Weed Whacking Warriors
    Weeding is a great way to relieve stress. While at home, take this time to pull out those pesky invasive weeds that travel through yards and into public lands. For instance, removing early invading weeds like slender false brome and hanging sedge can really help. Get details on these two plants from San Mateo Resource Conservation District or check out the free Weed Workers Handbook from the California Invasive Plant Council.


Nature Art

  • POST Coloring BookKeep a Nature Notebook
    Keep a nature notebook, recording your local nature explorations: observations, drawings, pressed fallen leaves or flowers, images and more. You never know what you’ll discover once you start looking!
  • Get Crafty with Nature Art
    Enjoy art and crafts with your family using everyday nature items. Go outdoors and find leaves, flowers and plants from around your home. Arrange your findings on top of a piece of paper on a stable, flat surface. Once you are happy with the arrangement, place another piece of paper on top. Use tape to secure the pages in place, then use a hammer to hammer over the entire arrangement. Once you have finished hammering, remove the top sheet of paper and remove remnants of plant material. Your nature art project is complete! Thank you to the Weekend Sherpa for sharing the idea.
