General Site Description: 

Our work focuses on a metropolitan area that includes the nation’s sixth largest city, Phoenix, as well as 22 other municipalities and spans Maricopa County and a small portion of Pinal County, Arizona. We engage biological, physical, engineering, and social scientists in research that provides a foundation for understanding urban socio-ecological systems in an arid, but rapidly growing, metropolitan area.

Purpose of Site : 

The Central Arizona–Phoenix Long-Term Ecological Research (CAP LTER) program advances research and education on urban ecology and urban socioecological systems. It is one of two LTER sites funded by the National Science Foundation that specifically studies urban ecology. The CAP LTER has been a leader in interdisciplinary science, bringing together teams of individuals from different fields to investigate the complex dynamics of the Phoenix metropolitan area and surrounding Sonoran Desert. Educating the next generation of urban ecologists is a core mission of the CAP LTER. The Ecology Explorers program engages K-12 students and teachers, while undergraduate and graduate students are active researchers whose work is published in leading scientific publications.
