Sutherland Native Plant Restoration Information - 9am to 12pm
Meet at the Sutherland Drive entrance to Shell Ridge. Leader will have some tools, but please bring your own if possible. Most of what we will be doing is hand pulling, prying or slicing of taproots of mustard in short annual grasses. This is easier than it sounds. Stout, sharp knives (like a hori-hori) or similar tools work very well. Minimum age 14. For more information or to sign up write to

Indian Valley Pond Information - 9am to 12pm
Come help plant native grasses and wildflowers along around the pond while learning about the native plants and wildlife in our Open Space. We will discuss how you can use these planting techniques for native plants in your own garden. The planting days also provide a chance to see what work has been completed around the pond and what future plans will bring. We will meet at the Marshall Drive entrance to Shell Ridge. For more information or to sign up contact Sean Micallef at Plants, tools, and some extra gloves will be provided (but please bring your own if you have a pair).

Grass Planting Information - 9am to 12pm
Help the Foundation plant native grasses and do other restoration activities at various locations. Plants, tools, and some extra gloves will be provided (but please bring your own if you have a pair). Most locations are near an open space entrance, but Deer Lake will require meeting at a specified parking area and taking a short hike to the work location.
