Habitat inventories conducted by the California Department of Fish and Game (DFG) of the west end streams in Jackson Demonstration State Forest (JSDF) have repeatedly revealed them to possess a high percentage of canopy cover and generally well-vegetated stream banks. However, their pools are often shallow and there is generally very little large woody debris (LWD) in the channel. It is believed that the addition of large woody material to stream channels could produce higher habitat quality in these streams for anadromous fish. Enhanced juvenile rearing and over-winter holding areas should im...

The FIA Annual Business Reports evaluate the performance of the FIA program to ensure accountability and transparency to FIA partners, supporters and customers. Modeled on a corporate business report, they contain basic business information about the FIA program including accomplishments, performance measures, plans for the next fiscal year, agreements with other parties, and basic financial and staffing data. These reports are prepared by the National Office staff of the FIA Program, U.S. Department of Agriculture, Forest Service, Washington, DC.See more information for fiscal years 2021 and ...

San Joaquin Valley communities will be among the fastest growing in the state during the next decade. The role of urban forests to enhance the environment, increase community attractiveness, and foster civic pride will take on greater significance as Valley communities strive to preserve and improve their quality of life. Urban and community forestry has been recognized as a cost-effective means to cool urban heat islands, improve air quality, and combat global warming.San Joaquin Valley communities can promote energy efficiency through tree planting and stewardship programs that strategically...

The Ruth Research Natural Area (RRNA) occupies a portion of the southwest-facing slope of South Fork Mountain in southwestern Trinity County. This long ridge has a remarkably even summit and has been touted as one of the longest continuous ridges known in the world. At the RRNA the slope of South Fork Mountain is dissected by several small intermittent streams, the two principal ones being Hobart and Choptoy creeks. Both of these creeks originate at several permanent springs within the RNA.

The Adorni Research Natural Area occupies a large portion of the Aikens Creek drainage, a second-order tributary of the Klamath River in the western Klamath Mountains province. Slopes are primarily northeast facing and are steep and prone to slumping. The area is on the boundary between ultramafic (peridotite) and metasedimentary schistose rock and contains both types. The entire RNA is forested, with no openings, save a few recent and rapidly colonizing slides.

The Fisherman's Camp Research Natural Area captures a steep area reaching from Deep Creek on its eastern edge to the forest boundary at the top of an unnamed ridge to the west. It is contained within the Upper San Gorgonio Mountains subsection of the Southern California Mountains and Valleys Section Ecological Unit. The RNA captures several small sub-watersheds and includes a variety of riparian conditions as well as extensive areas of westside ponderosa pine forest and the target Coulter pine forest. One association of Coulter pine and canyon live oak (Quercus chrysolepis) is only found in th...

The Black Butte Research Natural Area (BBRNA) occupies the northeast side of a steep, southeast-trending ridge. This ridge forms a major topographic boundary between the western maritime climatic region and the temperate interior. Terrain is steep with an elevation gain of 1300 feet (396 m) in approximately 0.6 mile (1.0 km). Slopes of 80 percent or more are common within the RNA. Because of its location and steep elevation gradient, the BBRNA supports a complex mosaic of vegetation types. These include extensive stands of knobcone pine, various forms of chaparral including areas dominated by ...
