Since this desert is the most biologically diverse of the four North American deserts, there are hundreds of wild animals and plant species. One of these animals is the cactus ferruginous pygmy owls, which live in the saguaro cacti. These owls are a protected species in the Endangered Species Act.

1. Lack of Water Even though the Sonoran Desert receives more rainfall than other North American deserts, it’s still a desert. There are no watering holes to refill water bottles or places to take a dip to get away from the heat. Dehydration and heat stroke are real threats for hikers and travelers.

3. Brown Recluse Spider Although not an aggressive spider, the brown recluse can still pose a severe threat to humans. When they feel trapped, they’ll bite. A stinging sensation accompanies the bite, and pain can last up to eight hours. The victim may see swelling, and a blister may appear.
