Nothing says “desert” like the Saguaro (swor’- oh) Cactus. Although it is associated with all American deserts, it actually has a very small range. It is found exclusively in the Sonoran Desert of southern Arizona, southeastern California and western Sonora, Mexico. Even there, its range is further limited by altitude and water. The Saguaro can only survive in a very specific set of environmental conditions.
This is one of the biggest Saguaros I’ve ever come across. We stumbled on to while hiking and geocaching in the back country of Catalina State Park in Oro Valley, AZ (near Tucson). Besides a couple dozen challenging geocaches, this mountainous 5,500 acre park has over 5,000 Saguaros but you’ll be hard pressed to find one bigger than this. It’s a good 50 feet high and is probably close to 200 years old.
Saguaros live to a ripe old age – up to 250 years. They don’t start growing arms until they are 75. Their roots are shallow – typically 4-6 inches with a 2 foot tap root – and spread out as far as the plant is tall. Saguaros store water like a camel’s hump. During the rainy season, it swells as it absorbs and stores water. A full grown Saguaro that has stored up water can weigh up to 5,000 pounds.
Early Native Americans used every part of the Saguaro. It was a source of water, which it stores internally and fruit which is said to be quite tasty. The spines were used as needles. Dead Saguaro are tough and woody. They were used for roofs, fences and furniture.
The Saguaro Cactus is not endangered but it is protected. Both Arizona and the feds have strict laws and severe penalties for unauthorized harvesting, digging or damaging these magnificent plants.
Saguaro also provide homes to a variety of birds and small mammals. We once saw a bobcat sitting on top of one watching the world go by. How he got up there is beyond me. Getting down was probably a bit dicey also. I know it would be for me and Natasha.
