Monitoring Sediment and Water Quality in Clear Creek

Clear Creek is a small alpine stream that begins near Lake Tahoe in the Sierra Nevada. The creek flows roughly parallel to U.S. Highway 50 and discharges to the Carson River near Carson City, Nevada. The Nevada Department of Transportation (NDOT) is concerned about how historical and ongoing development in the Clear Creek drainage basin has/is affecting Clear Creek and its sediment-transport...

Ecological Drought in Riparian Ecosystems

Drought is killing riparian trees along many rivers in the western United States. The cause can be increasing temperature or decreasing precipitation, flow or water-table elevation. At multiple locations we are relating water availability to physiological measurements of tree survival and water stress, such as ring width, carbon stable isotope ratio and branch hydraulic conductivity. These...

Biological Invasions of Riparian Ecosystems

Beginning in the early twentieth century, non-native trees and shrubs, including tamarisk (also commonly known as saltcedar) and Russian-olive, were introduced to the United States for use as ornamental plants and in erosion-control plantings. These plants spread extensively, becoming the third and fourth most frequently occurring woody riparian plants in the American West.

Habitat restoration as a means of controlling non-native fish in a Mojave desert Oasis

Non-native fish generally cause native fish decline, and once non-natives are established, control or elimination is usually problematic. Because non-native fish colonization has been greatest in anthropogenically altered habitats, restoring habitat similar to predisturbance conditions may offer a viable means of non-native fish control. In this...
