Flowing north from Mexico into the Gila River in southeast Arizona, the San Pedro is one of the Earth's the most biologically diverse and important ecosystems. It supports 400 species of birds (nearly half of the U.S. total), 100 species of butterflies, 83 species of mammals and 47 species of amphibians and reptiles.
Nevertheless, the river is drying up due to unsustainable sprawl and agribusiness. Ground water pumping associated with Fort Huachuca is the single biggest contributor to the deadly overdraft of the river.
In response to an Earthjustice lawsuit filed on behalf of the Center for Biological Diversity, a federal court ruled that a US Fish and Wildlife Service opinion finding Fort Huachuca's 10 year operation plans compatible with the Endangered Species Act was wrong.
Fort Huachuca will now have to develop a new, stronger water conservation plan and re-submit it for review to the U.S. Fish & Wildlife Service. Army officials have appealed the district court ruling. Earthjustice will be there to defend it.
