The patch of endangered San Diego ambrosia just inside the Par Four entrance to the San Diego National Wildlife Refuge needs us to pull out the weeds that are impeding it from thriving. Join EDI for a quick hit on this problem... just a couple hours in the cool morning temps should do it!

Gloves, tools, drinks, and snacks provided.
