ECOSTART II (2003-2005) is a continuation of the first ECOSTART, but with a sole focus on the Arizona portion of the San Pedro Basin. ECOSTART II is a watershed-based environmental education program that builds the capacity of Sierra Vista schools to educate basin students about water conservation, basic ecological concepts, and bird and fish habitats tied to the San Pedro riparian corridor in southeastern Arizona.

ECOSTART II links University of Arizona educators, the Arizona-Sonora Desert Museum, the Tucson Audubon Society, and Arizona Project WET with Sierra Vista elementary school teachers and their students, the Sierra Vista Water Wise school program, and the Friends of the San Pedro in a series of teacher workshops and student/teacher field trips designed to address community and school needs for knowledge and understanding of the relationships between a geographic sense of place, ecosystem functioning, and natural resources.

The overall goal of ECOSTART II is to improve the understanding of geography and ecological processes and to encourage the participation of students in the conservation of water within a basin context. Its specific goal is to expand Water Wise, the existing water education program in Sierra Vista, by adding other aspects of environmental education and geography, and to increase the number of teacher trainers from one to four so that larger numbers of students in the basin may be included.
