The Bell Meadow Research Natural Area is distinguished by its well-developed aspen forest, riparian thickets, and wet and dry meadow vegetation. It is underlain primarily by granitic rock and riverine and lacustrine alluvium, with a small amount of Pliocene volcanics in the northeast portion. The meadow is a product of repeated overbank flood deposition separated by non-flood periods of organic accumulation. The meadow may be divided into an upper and lower part, separated by a narrows bordered on each side by granitic outcrops. The present meadow vegetation is a mosaic of riparian willow thic...

The majority of the Grizzly Mountain Research Natural Area (GMRNA) is underlain by mesozoic granitic rock of the Sierra Nevada Batholith, with some metamorphics and gneissic intergrades between the metamorphic and granitic rock. The GMRNA lies entirely on the northern slopes of Big and Little Grizzly Mountains. These two mountains are separated by a small canyon (Paps Gulch) with a small stream that is permanent near its confluence with Bull Creek. All slopes within the area are part of the Bull Creek drainage. Prior to the 1987 fire, a nearly continuous stand of relatively young black oak str...

The W.B. Critchfield Research Natural Area (WBCRNA) is on the west slope of the Sierra Nevada, and consists of the uppermost watershed of Bourland Creek, a glaciated valley opening to the southeast. Exposed south-facing slopes, ridge crests, and open rocky areas primarily support Huckleberry oak scrub. Red fir forest is the predominant cover type on lower slopes and portions of the valley bottom, with lodgepole pine forest and aspen forest also present in these areas. Small stands of pure Jeffrey pine (Pinus jeffreyi) grow in rocky areas at the head of the valley. Montane meadow and montane fr...

Spawning surveys were conducted for three years in Mendocino County streams. The results from the last two years of surveys are reported here. Surveys were conducted in seven watersheds in 1991 1992 and in ten watersheds in 1990-1991. These surveys were conducted to as a means to evaluate the effectiveness of restoration efforts to restore salmon populations. The populations of chinook and coho salmon were estimated by several methods including marking and recapture of carcasses, area-under-the-curve (AUC) method and from numbers of redds. A new model was developed to estimate spawning numbers...

For the past three decades, researchers from the Pacific Southwest Research Station's Redwood Sciences Laboratory in Arcata, California, and the California Department of Forestry and Fire Protection (CDF), Jackson Demonstration State Forest near Fort Bragg, have been studying the effects of logging northern California watersheds. Their findings have identified the extent and nature of hydrologic, erosion, and sedimentation impacts of logging operations on watersheds in this area.Cooperation between CDF and the Station dates from 1962. It has been a productive division of labors, with CDF super...

The Forest Service Research Natural Areas (RNA's) Program maintains a network of 289 established areas and over 300 candidate areas representing common and unique natural ecosystems on National Forest System lands in the United States. These areas are managed in conditions minimally disturbed by human activities for nonmanipulative research, monitoring, education and to maintain natural diversity and ecological processes. Prompted by desires to improve the effectiveness of the current program and realizing that opportunities exist for an expanded role for RNAs in ecosystem management, RNA Coor...
