Family-owned forest lands make up about 7 million acres, around 20 percent, of California's forests. Most of these acres are owned and managed as small parcels (10 to 100 acres) by nonindustrial private landowners. The USDA Pacific Southwest Research Station, in partnership with CAL FIRE and the USDA California Climate Hub, created the Forest Management Handbook for Small-Parcel Landowners in the Sierra Nevada and southern Cascade Range to provide concise and thorough information to help these landowners develop a sound forest management strategy for their property.

Forest management handbook for small-parcel landowners in the Sierra Nevada and southern Cascade Range. Stine, Peter A.; Ostoja, Steven M.; McMorrow, Stewart. 2021. Info. Fore. PSW-INF-1. Albany, CA: U.S. Department of Agriculture, Forest Service, Pacific Southwest Research Station. 85 p.

In excessive amounts, nutrients like nitrogen and phosphorus can disrupt water chemistry and, ultimately, negatively affect water quality in forest streams. Nutrient pollution can degrade water for drinking, recreation, and wildlife and fish habitat. A new report published by the USDA Forest Service's Pacific Northwest (PNW) Research Station synthesizes studies of the biological responses to stream nutrients from 17 long-term research sites across the country, including these four in California and Hawaii:

Hawai‘i Experimental Tropical Forest, Hawai‘i.

California Coastal Sage, Chaparral, and Oak Woodlands: San Dimas Experimental Forest, California.

Coast Range: Caspar Creek Experimental Watersheds, California

Sierra Nevada: Kings River Experimental Watersheds and Teakettle Experimental Forest, California.

Biological responses to stream nutrients: a synthesis of science from experimental forests and ranges. Ryan, Douglas F., ed. 2021. Gen. Tech. Rep. PNW-GTR-981. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 522 p.
