These estimates are used in federal funding allocations, as denominators for vital statistics rates and per capita time series, as survey controls and for monitoring recount demographic changes. With the July 1 estimate, the Census Bureau reviews the estimates for each year back to the last census. Previously published estimates are superseded. The state data are released at the end of the calendar year. The county and subcounty population data are updated in late spring or early summer.
Grass Valley Wilderness Area. Parks âº California âº Ridgecrest Rec. Management Area âº Points of Interest âº Forest/Natural Area. Grass Valley Wilderness Area is a series of scattered hills, reddish-brown to yellow in appearance and gently rising to elevations from 200 to 600 feet above the desert valley floor. Vegetation is typical of a creosote bush scrub community with a number of Joshua trees. Some wildlife in the area are raptor foraging and desert tortoise, along with Mohave ground squirrel habitat. This wilderness is bisected with a vehicle corridor running north-south, and visitors must remain on this route if traveling in any sort vehicle.
The valley reach is that portion of the river from the confluence with the San Joaquin River upstream to the Orange Blossom bridge (east of the city of Oakdale). It flows through an area that is highly developed agriculturally and whose major crops are fruits and nuts. This reach is approximately 47 river miles in length and has a gradient of 0.03 percent. The major habitat type within this reach, valley foothill riparian, is primarily found bordering the Stanislaus River. This habitat is characterized by a canopy layer of cottonwoods, California sycamores, and valley oaks. Subcanopy cover trees are white alder, boxelder, and Oregon ash.
