Saguaro National Park’s two districts outside of Tucson, Arizona are characterized by water features, pine forests, and mountains to the east and protected desert vegetation to the west. Each side of the park is part of its own Important Bird Area—each a diverse ecosystem that supports the desert’s roadrunners, woodpeckers, and quails. As the climate changes, dozens of species could be extirpated from the park or face worsening conditions. These include Harris’s Hawk, Mexican Spotted Owl, and various wren species. It is recommended that park managers emphasize protecting existing habitats and reducing the effects of nonnative species.

Suitable climate for these species is currently available in the park. This list is derived from National Park Service Inventory & Monitoring data and eBird observations. Note, however, there are still imperfections in these datasets.

These are species that may find the new climate conditions of this park suitable by 2050. But projected changes in climate suitability are not definitive predictions of future species ranges or abundances. Numerous other factors affect where species occur, including habitat quality, food abundance, species adaptability, and the availability of microclimates.

Within this park, suitable climate for these birds ceases to occur by 2050. Species may either adapt to the park’s new climate or may follow suitable climate elsewhere.
