In 1933, President Herbert Hoover conserved the lands that later became Saguaro National Park in order to protect one of the nation's most unique habitats.  The saguaro cactus (Carnegiea gigantea) -- found only in the Sonoran Desert -- is the largest cactus in North America, growing to a height of 50 feet and often weighing seven tons or more.

To fulfill its mission of protecting it namesake plant, Saguaro National Park conducts ongoing research to evaluate the complex ecological interrelationships that govern the health and character of saguaro stands.

Through the FOSNP Adopt a Saguaro program, you can support this critically-important scientific research, and help preserve and protect these impressive "sentinels of the desert."

With Adopt a Saguaro, Friends of Saguaro provides the Park with funding to support saguaro inventories, monitoring and research.

Saguaro adoptions make perfect gifts, and are great educational tools.  More than 100 schools across the nation have participated in the Adopt a Saguaro program -- utilizing gifts from students, parents and teachers to support the Park's famous saguaro cacti.
