Desert Defenders

Invasive species are one of the biggest threats to healthy ecosystems. They often crowd out native species, decrease biodiversity and increase wildfire risk. Join the new Desert Defenders program to help us find and remove these plants!

Desert Defenders is a citizen science program focused on finding, mapping and removing invasive species at local parks and preserves. The plant species that we focus on are known to have a moderate to severe impact on local ecosystems, and a few pose a risk for our community by raising the fire risk and even worsening seasonal allergies. The data collected through the tireless work of our Defenders is crucial for park staff and land managers to protect the desert parks we all love.

Wildfire and Invasive Plants

The Sonoran Desert is not fire adapted. As climate change and invasive species transform our landscape, our desert needs your help to thrive. Take a look at our Desert Defenders wildfire infographic to learn how you can help.

Stinknet

Stinknet (Oncosiphon piluliferum) is causing havoc in central Arizona, if left unchecked, it could destroy much of the desert landscape it blankets. Battling this deceptively pretty invader calls for an army of conservationists, ecologists, community scientists, firefighters, master gardeners and homeowners.
