Join us at Lewis Springs next to the San Pedro River to remove invasive Johnsongrass around endangered Eryngo plants native to this site.
About this Event

The Work

We will be removing invasive Johnsongrass from around small endangered Eryngo plants that are native to this site. The Johnsongrass threatens the recruitment of the endangered plant and uses water that would otherwise sustain a series of large wet meadows at Lewis Springs.

What to Expect/Bring

Folks staying through the weekend should bring their own camping gear (or contact us if you need to borrow some) and meals for the weekend — a minimum of two breakfasts, two lunches, and two dinners, with snacks.

  • SIA will provide potable water, and folks are welcome to bring their own as well. There is water at the campsite to refill from, but none at the worksite.
  • Be prepared to unplug — there is limited or no cellphone or internet service where we'll be camping and working.
  • Bring camping gear: tent, sleeping bag, sleeping pad, etc. We have extra camping gear available to borrow. Please contact our staff listed below if you would like to use some of our equipment.
  • Bring work clothes, work gloves, and appropriate close-toed boots/shoes that you are happy to hike in and don't mind getting dirty or damaged.
  • Bring sun protection: sunscreen, long-sleeves, hat, etc.
  • Bring a refillable water bottle and a daypack for snacks and gear.

We will be removing invasive Johnsongrass and bagging seedheads for disposal off-site. Be prepared for getting dirty as we will also be digging and carrying plants (which are quite large). Worksites may be steeply sloped and uneven, with the potential for loose footing.
