Over the past two hundred years, 90% of native wetland habitat has been lost in California. Audubon California will work to create seasonal wetland habitat in the Sacramento Valley to sustain healthy migratory shorebird populations. They do this by ensuring water stays on the right land at the right time and at the right depth during shorebird migration. By 2023 Audubon hopes to have provided 3,500 acres of seasonal wetland habitat where land would otherwise have been dry, helping to support shorebird populations, improve water quality and encourage groundwater recharge.
