A beautiful patch of endangered San Diego ambrosia just inside the Par Four entrance to the San Diego National Wildlife Refuge in Rancho San Diego needs our help. Non-native invasive weeds are hampering its ability to thrive. Please join us 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.
Note: Parking is along the street for this trailhead. Please be respectful of the neighborhood and resident's driveways.
