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.  

We recently lost our legal effort in the State court system to prevent the SunZia infrastructure corridor from being routed through the most remote and ecologically sensitive portion of the San Pedro Valley,  despite the existence of alternative routes through Arizona that would have been 100% co-located with existing power line corridors. We faced great headwinds when the Southwest Chapter of the National Audubon Society endorsed this extremely inappropriate and avoidable route without first consulting with local volunteer conservationists and Tribal Nations during SunZia's recent amendment process.

However, local Tribal Nations continue their fight in the Federal court system to gain recognition of lower San Pedro Valley as a traditional indigenous cultural landscape.  We will soon be posting more about this effort and the remarkable legal support being provided by the Center for Biological Diversity (CBD).  Meanwhile, please donate to the Lower San Pedro River legal programs at CBD, or feel free to donate directly to us.  

Legal representation is necessary to overcome the lobbying efforts of various interests that seek to irresponsibly exploit the lower San Pedro region's remarkable ecological and cultural landscape.  In our first 11 years of existence, our all-volunteer organization learned that excessive academic efforts and repeatedly talking with stakeholders at meetings is far less effective at protecting this special landscape than partnering with organizations and tribal governments that are willing to take legal action. This is why we have narrowed down our mission statement, as presented at the top of this home page.  Feel free to contact us at LowerSanPedro@gmail.com



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. The lower San Pedro watershed has become the default repository for mitigation of impacts caused by this 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.



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.

Imagine this spectacular watershed from the perspective of those who live here.


Because words are insufficient, please enjoy this short video. In it, you can clearly see that this stunning ecosystem—and the plants, animals, and landforms that comprise it—make a compelling case for conservation.
