A Partners for Fish and Wildlife grant from the U.S. Fish and Wildlife Service is helping Sweetwater Center restore wildlife habitat on our private land. Starting in August 2016, we are establishing native grasses, milkweed, and pollinator plants and removing invasive exotic Malta star thistle.
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 have spent over 35 years studying these plants, which grow only in our Sonoran Desert. Their recent publication in the scientific journal PLoS One documents findings from 75 years of annual saguaro censuses at Saguaro National Park in Tucson.
