Protecting
An Ecological Treasure of International Importance
A Voice for Volunteer Conservationists
The mission of the Lower San Pedro Watershed Alliance is to protect the ecological integrity and associated indigenous cultural heritage of the lower San Pedro region of Arizona, primarily through voluntary and effective actions by local citizens.
Due to rapid growth in Arizona's Sun Corridor, the San Pedro River is the last remaining major natural and intact river ecosystem in southern Arizona. As a result of its rich biodiversity, the lower San Pedro watershed has become the default repository for the mitigation of adverse ecological impacts caused in other parts of the state by such rapid growth.
By joining with the LSPWA, you help demonstrate that organizing at the watershed level is an important movement in the desert Southwest, one that transcends county and community boundaries. Together, let's ensure that this endangered landscape offers future generations far more than yet another land and water base for resource exploitation.
The San Pedro River Valley today faces unprecedented industrial threats to its survival. Find out how LSPWA has been challenging these threats, in its efforts to conserve this crucial desert waterway:
Get the details about LSWPA’s upcoming Public Meeting, Feb. 11 from 6 p.m.-7:30 p.m. at the Mammoth Community Center, where we will address past, current and future concerns in the lower San Pedro watershed. Our partners will be on hand to discuss lessons learned and strategies to save our water resources and natural habitats from industrial threats.

A Significant, Singular Landscape
The San Pedro corridor has become the most important north-south migratory bird flyway within Arizona. The lower San Pedro watershed also harbors one of the richest remaining fish, reptile, amphibian, and mammalian habitats in the nation, and is the key to protecting several threatened and endangered species.

Documents Submitted
Canadian-owned Pattern Energy Corporation ignored the existence of low-impact alternatives and started building the haphazardly-planned SunZia Transmission Project through 33 miles of the most remote and ecologically sensitive portion of the San Pedro Valley. LSPWA stood against this travesty in the Arizona Courts.
