Saguaro National Park Feature
Plants and Wildlife in Saguaro
The saguaro may be the centerpiece of Saguaro National Park, but more than 1,200 plant species, including 50 types of cactus, thrive in the park. Among the most common cacti here are the prickly pear, barrel cactus, and teddy bear cholla—so named because it appears cuddly, but rangers advise packing a comb to pull its barbed hooks from unwary fingers.
For many of the desert fauna, the saguaro functions as a high-rise hotel. Each spring the Gila woodpecker and gilded flicker create holes in the cactus and then nest there. When they give up their temporary digs, elf owls, cactus wrens, sparrow hawks, and other birds move in, as do dangerous Africanized honeybees.
You may not encounter any of the park's six species of rattlesnake or the Gila monster, a venomous lizard, but avoid sticking your hands or feet under rocks or into crevices. Look where you’re walking; if you do get bitten, get to a clinic or hospital as soon as possible. Not all snakes pass on venom; 50% of the time the bite is "dry" (nonpoisonous).
Wildlife, from bobcats to jackrabbits, is most active in early morning and at dusk. In spring and summer, lizards and snakes are out and about but tend to keep a low profile during the midday heat.
