Upcoming Annual Event Sponsored by Friends of White Tank and Maricopa County
Volunteers like you are needed to help "refresh" the park by removing trash and unwanted debris. Trash bags, hand-operated tools to pick-up trash, and other materials will be provided. Please bring your own gloves; we will have a very limited supply on hand.

Invasive Species Removal Days
Maricopa County needs volunteers like you!
Help locate and remove invasive species from the Park. This is a hands-on activity. Be prepared to pull them out, bag them, and ensure these unwelcome species don't come back or spread.
In June, 40+ volunteers learned how to map invasive species using the new Maricopa County Parks Desert Defenders Field mobile app. Together, we removed approximately 59,000 invasive plants from 34-acres of land within four parks. The native plants and varied desert dwellers of our parks appreciate your hard work!
• White Tank Mountain Regional Park: 7.74 acres and 24,417 Sahara Mustard plants
• Cave Creek Regional Park: Two acres and 23,500 Stinknet plants
• Estrella Mountain Regional Park: 0.5 acres and 6,000 Sahara Mustard plants
• Spur Cross Ranch Conservation Area: 23.47 acres and 5,098 plants -- Sahara Mustard, Stinknet, and Fountain Grass
