The river valleys of the Yakima Basin create broad floodplains filled with cottonwoods, willows and other deciduous trees. These riparian forests are oases in our arid lowlands, and support a wide range of migratory birds, reptiles and amphibians and other wildlife. The long-term health of these riparian areas depends on periodic rearrangement of the floodplains by floods. Conservation efforts focus on protecting the river corridors and allowing the river to move within them, while ensuring that homes, roads and other infrastructure are protected from the negative impacts of floods. Many of the projects aimed at protecting and enhancing habitat for at-risk fish species also directly benefits riparian forests and the wildlife that depends on them.
