Sam Earnshaw

Author and Expert in Hedgerow and Farmscape Installation and Management
Watsonville, CA

Sam Earnshaw is the author of Hedgerows and Farmscaping for California Agriculture: A Resource Guide for Farmers (2018), which is an acclaimed tool in the protection of ecological balance and increased farm productivity. (The guide is available on the Community Alliance with Family Farmers (CAFF) website.) Since 1996, Mr. Earnshaw has planted hedgerows, windbreaks, grassed waterways, and riparian plantings on over 100 farms. He continues to work on the design and installation of conservation plantings and is a Technical Service Provider with the Natural Resource Conservation Service (NRCS). Hedgerows and grassed waterways are increasingly being planted on farms and can have multiple functions, serving as: habitat for beneficial insects, pollinators and other wildlife; erosion protection and weed control; waterway stabilization; windbreaks; non-point source water pollution and groundwater pollution reduction; a surface water infiltration tool; a buffer from pesticide drift, noise, odors, and dust; living fences and boundary lines; biodiversity enhancement; and an aesthetic resource. Many hedgerow plants attract native bees and other pollinators, and some, such as citrus or other fruit trees and herbal plants, have economic returns. As with any planting, problems and issues can be dealt with through management practices.

In 1992, Mr. Earnshaw began working as Lighthouse Farm coordinator for CAFF, sponsoring monthly meetings and field tours for farmers, sharing techniques in biologically based farming techniques. His work with local California growers in Watsonville, Santa Cruz, Salinas, and Hollister through this program led to CAFF's leadership in land use and water issues on the Central Coast. In the mid-1980’s, he and his wife, Jo Ann Baumgartner, started their farm in Santa Cruz, California (Neptune Farms) and marketed organic vegetables and cut flowers to retail stores, farmers' markets, and wholesalers. Mr. Earnshaw has a degree from University of California Berkeley (1974) with studies in forestry.
