The practice of growing hedgerows stems from all the way back to the Medieval times of England and Ireland.
Hedgerows can increase the beauty, productivity, and biodiversity of a property and are especially beneficial for farms.
Modern day hedgerows are used as a field border to enhance the habitat value and productivity of farmland.
To date, the creation of hedgerows and other restored habitat areas on California farms remains low.
This is in part because of a lack of information and outreach that addresses the benefits of field edge habitat, and growers’ concerns about its effect on crop production and wildlife intrusion.
Native hedgerows on farm edges benefit wildlife, pest control, carbon storage and runoff, but hedgerow planting by farmers in California is limited, often due to establishment and maintenance costs.
Field studies in the Sacramento Valley highlighted that hedgerows can enhance pest control and pollination in crops, resulting in a return on investment within 7 to 16 years, without negatively impacting food safety.
What if hedgerows could provide a source of farm income, to offset costs AND benefit the local environment?
Currently the UC Sustainable Agriculture Research and Education Program (SAREP) is collaborating with Cloverleaf Farm in Solano County and several other growers in the Central Valley and coastal counties to assess and develop the potential for elderberries to become a commercial specialty crop, with a focus on hedgerow-grown elderberry production and marketing for small- and mid-scale California farms.
UC Agriculture and Environment Academic Coordinator, Sonja Brodt believes that elderberries may be the intersection of sustainable farming, super nutrition, and economic viability.
At the 2019 Elderberry Field Day Sonja explained, “Elderberries may have the potential to combine crop production with environmental conservation functions in a way not typically seen on California farms. This model would enable small- and medium-scale farmers to receive a direct income from a farm practice that benefits the ecosystem as well.”
Farms like Cloverleaf use elder trees as hedgerows on their fields to increase habitat value and crop pollination while also making a profit on the side by selling elderberry products, such as jams, syrups, and flower cordials.
Additionally, with growing consumer interest in health foods, elderberry product sales nationwide have jumped 10-50% in recent years but almost no commercial supply originates in California.
The berries and flowers of elderberry are packed with antioxidants and vitamins that may boost your immune system.
According to recent research, elderberries can help tame inflammation, lessen stress, and even help protect your heart!
There are about 30 types of elder plants and trees found around the world.
The European version (also known as Sambucus nigra) is the one most often used in health supplements, however, recent attention has been drawn to the California elderberry (Sambucus caerulea).
Cloverleaf Farm has been an active partner with SAREP by monitoring the success level of elderberries planted and comparing results between the California elderberry and the European elderberry.
So far their findings show that California elderberries have a greater success rate when grown in Mediterranean climates compared to the European elderberry and attract more native pollinators, which benefits the crop yields.
In addition the UC Davis Food Science and Technology department is currently working on a elderberry project, led by Katie Uhl, focusing on the bioactive components unique to California elderberries that can be beneficial for human health.
While a diversity of plant species makes for the most effective hedgerows, the California elderberry is proving itself to be a perfect foundation species as it provides excellent environmental habitat and great potential for profits by selling the berries as health food products!
You can find Cloverleaf Farm elderberry syrups here at the Davis Food Co-op, along with many other elderberry products in our Wellness department!
