Site Description
The relocatable aquatic Domain 17 site, Upper Big Creek (BIGC), is a wadeable stream on the western slope of the Sierra Nevada Mountains with a watershed size of approximately 10.9 km2. BIGC spans an elevation range of 1003 m - 1700 m and passes through mixed mature cottonwood trees, short grasses, and shrubs. The BIGC catchment is entirely located in the Sierra National Forest, just north of the NEON relocatable terrestrial site, Soaproot Saddle (SOAP). This site is part of the US Forest Service's Major Land Resource Area (MRLA) 22A - Sierra Nevada Mountains and is within the Southern Sierra Lower Montane Forest ecoregion (SOAP soil summary).Total data products planned for this site: 79

Vegetation
The Upper Big Creek Basin ecosystem is dominated by coniferous forest consisting of ponderosa and sugar pines (Pinus ponderosa and Pinus lambertiana), incense cedar (Calocedrus decurrens), sequoia (Sequoiadendron giganteum), and white fir (Abies concolor). The understory is primarily scrub-shrub. The riparian forest is dominated by cedar, pine, and fir with a small percentage (<1%) of California black oak (Quercus kelloggii), white alder (Alnus rhombifolia), Oregon ash (Fraxinus latifolia), and black and Fremont cottonwood (Populus trichocarpa and Populus fremontii). The understory is scrub-shrub with ferns and grasses.The riparian forest floor contains much higher amounts of organic matter due to dead-fall, shading and higher humidity.
Hydrology
The flow regime of Upper Big Creek (BIGC) is typical of snowmelt dominated mountainous streams in the west. Base flows are lowest in the winter (November - March) and highest in the late spring (April – June). BIGC has a mean base flow of 10 liters per second in the autumn months. Snow melt begins in March and peaks in April. Discharge during the peak flow month of April is approximately 21 times greater than base flow.
