Sunol AgPark Hedgerow Development

Sunol AgPark Hedgerow Development

Funders: San Francisco Public Utilities Commission, Natural Resources Conservation Service, Environmental Quality Incentives Program, American Honda Foundation

Partners: Alameda County Resource Conservation District

Date of project: 2008 – 2016

Hedgerows serve multiple functions on the farm and as part of the Sunol AgPark’s natural resource stewardship.

Filter Strip Hedgerow for water quality protection: SAGE installed a 600 foot by 15 foot shrub and grass filter strip on the western edge of the farm to protect the adjacent Arroyo de la Laguna from farm-related sediment. The filter strip consists of a mix of native shrubs and annual and perennial grasses and wildflowers.

Hedgerows for Pollinator and Beneficial Insect Habitat: SAGE and partners established 600 foot by 5 foot native plant hedgerow to provide habitat for pollinators and other beneficial insects. The hedgerow was designed and planted as part of SAGE’s Youth Bridging Nature and Agriculture Program for high school students.

Hedgerow Path in Spring

Youth Bridging Nature and Agriculture (2011-13): SAGE’s education programming included a service learning program serving high school students. The program involved two classroom visits and two field trips to the Sunol AgPark. In the classroom, students learned about green career opportunities and heard from mentors and speakers working in environmental and agricultural careers. At the Sunol AgPark, students designed and planted a 100’ section of the pollinator hedgerows, including drawing up and detailing out schematics, planting in the hedgerow and labeling native plants.
