Long Term Saguaro Study

Seventy-five years covers much of a human life, but only about half the life span of the average saguaro cactus. Sweetwater Center board members Tom Orum and Nancy Ferguson’s recent publication in the scientific journal PLoS One documents findings from 75 years of annual saguaro censuses at Saguaro National Park in Tucson. Nancy and Tom have spent over 35 years studying these plants, which grow only in our Sonoran Desert. Hear Don Swann, biologist at Saguaro National Park, talk about what we can learn from this long-term study.
