An Ecological Treasure of International Importance
United in Our Efforts
The Lower San Pedro Watershed Alliance (LSPWA) is dedicated to uniting conservation minded individuals, groups, and agencies to protect a threatened riparian ecosystem and its supporting watershed.
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.
