Phoenix was orgnially settled near the confluence of the Salt and Gila Rivers as an agricultural community, but it has grown into the sixth largest city in the United States. Most of Arizona is a rugged, desert landscape. Most of the population in the Phoenix-metro area live within the urban core. That urban core has sprawled. The Valley of the Sun has an extremely low density compared to similar sized metropolitian areas.
Because of the desert climate and georgraphy, Phoenix has unique wildlife such as the desert cottontail rabbit, the antelope ground squirrel, the jackrabbit, ringtail, and twenty-eight species of bats. Situation near two rivers, the Salt River Valley provides habitats for a variety of wildlife.
Where there are people, there will be food and water. And with nearly three hundred sunny days, animals are active year round. In addition to Arizona’s unique desert wildlife, nuisance wildlife in Phoenix includes bats, raccoons, squirrels, opossums, birds, rats, and mice.
