Organ Pipe Cactus National Monument's Vital Signs report provides information on the status and trends of ecosystem drivers, landscape scale indicators, rare and sensitive species, stressors, and other focal resources. In doing so, it provides a deeper understanding of diverse monument resources and processes which in turn helps us in our efforts to conserve this beautiful Sonoran desert park. Management concerns have grown from a focus on adjacent land use and recovery from grazing and mining to include climate change, invasive species, highway traffic, and illegal immigration. The insights that this report provides are vital to our understanding of biological patterns and the general health of the Sonoran Desert ecosystem.

Gila Monsters are one of only two species of venomous lizards found in North America. You can find them in the late spring through early autumn at ORPI. They move really slow, and you have to try pretty hard to get bit. We don't recommend it. It hurts, and they don't let go.
