The Salton Sea is one of the most important places for birds in North America and is in danger of losing its ecological value. If it does, we will lose a vital part of the Pacific Flyway and face a toxic dust bowl that will threaten public health for more than a million Californians.
As part of the Colorado River Delta, the sea filled and dried for thousands of years prior to its current, 35-mile-long incarnation, which came into existence as the result of a massive flood of the Colorado River in 1905. The 350-square-mile sea has partially replaced wetland habitat lost to agricultural and urban conversion in the Colorado River Delta, California’s coast, and the San Joaquin Valley.
The sea is a globally significant Important Bird Area. For more than a century, the sea has served as a major nesting, wintering, and stopover site for millions of birds of more than 400 species. Today, tiny Eared Grebes winter by the thousands in rafts far out on its surface. American White Pelicans roost on mudflats and fish for tilapia in its shallows.
Recently, its water level dropped to the point that colonial seabirds began abandoning nesting sites en masse in 2013, and shallow, marshy habitat areas at the sea’s edge have begun to rapidly vanish, particularly at the south end. And in 2017, inputs of Colorado River water that have been maintaining a minimum sea level are scheduled to end, as more water is transferred from local agricultural uses to urban uses on the coast. As less water flows into the sea, it will shrink considerably, becoming more saline and eventually inhospitable to birds, fish, and insects.
Audubon California has the opportunity to help address some of the immense challenges of the Salton Sea.
Research about how much habitat -- and what kind -- birds are using at the Salton Sea should guide restoration.
San Diego Audubon Society recently partnered with an elementary school to educate students about birds that rely on the Salton Sea.
Audubon President David Yarnold writes today in the Los Angeles Times about how short-sighted management of water in the arid West is putting birds -- and people -- at risk. Speaking about the shrinking saline lakes -- such as the Salton Sea and the Great Salt Lake -- he notes that birds are incredibly reliant on these ecosystems that have been increasingly destabilized by diversions.
"Because water birds in the West depend on the region’s entire network of salt lakes, these declines could be catastrophic for the global populations of some species. For instance, 99% of the North American population of eared grebes — small waterfowl distinguished by bright red eyes that are framed by sassy tufts of golden feathers — depends on western saline lakes to survive their long migrations. What’s more, dams, diversions, extended drought and water demand along the Colorado River have devastated cottonwood-willow forests and other native river habitat. While this riverbank habitat accounts for less than 5% of the regional landscape, it supports more than 40% of all bird species in the Southwest."
