Promoting Pollinators with Agroforestry

Plant pollination by animals is critical for healthy ecosystems and an estimated 85% of the world’s flowering plants depend on animals, mostly insects, like bees, for pollination.

Trees and Shrubs Protect Crops and Generate Income for Farmers

Across the United States, farmers are taking innovative approaches to foster environmental stewardship and economic viability through a common conservation practice called the riparian forest buffer. Supporting production while enhancing conservation is an important goal of both US Department of Agriculture Secretary Perdue’s Agriculture Innovation Agenda (PDF, 196 KB) and of the USDA Forest Service. Agroforestry, the intentional integration of trees and crops and/or livestock to meet economic, conservation, and social goals, is one strategy that offers many innovative “productive conservation” options, including riparian buffers.

Why the Trees Outside Forests Count

Windbreaks and other agroforestry practices provide a wide range of agricultural production and conservation benefits, helping farmers and furthering the goals of U.S. Department of Agriculture Secretary Perdue’s Agriculture Innovation Agenda (PDF, 196 KB). Windbreaks are designed to increase crop yields, reduce erosion, and improve soil health while also providing other conservation benefits like wildlife habitat.

Caring for the Land and Serving People through Agroforestry

People become interested in agroforestry for a wide range of reasons including improving water quality, enhancing wildlife habitat, reducing soil erosion, and increasing crop and livestock production.

Agroforestry, the intentional combination of trees with crops or livestock, is designed to support landowners’ conservation and production goals. Through U.S. Forest Service, state agency, and other technical assistance providers who work with landowners, the National Agroforestry Center works with partners to care for the land and serve people.

Five Ways Agroforestry Can Grow Forest Products and Benefit Your Land, Your Pockets & Wildlife

Much of the beauty in American agricultural landscapes is complemented by the trees in those landscapes. We depend on these tree’s products every day–from the paper our children use in school, to many of the fruits we eat, the wood burning in our fireplaces, and the wildlife habitat created by those trees and forests.

Forests are vital to our economy, as well. Trees are part of forest ecosystems that play a critical role in our livelihoods, providing environmental, economic and social values. Agroforestry practices support agricultural production and help improve water quality and air quality, soil health, and wildlife habitat. These working trees can also grow fiber, food, and energy. And with the U.S. Census Bureau projecting a population surge to nine billion by 2044, forests and agroforests can help meet the growing demands for food, shelter, medicine, and recreation.

Partners in Agroforestry

When thinking about how to reduce run-off from potato fields in New Brunswick, Canada, researcher Josée Owen of Agriculture and Agri-Food Canada turned to a tool created by Mike Dosskey, a U.S. Forest Service researcher at the USDA National Agroforestry Center.

With others at the University of Kentucky and the Forest Service, Dosskey created AgBufferBuilder, a GIS-based computer program used for designing vegetation buffers around agricultural fields. Soil can erode, and fertilizer and pesticides off of fields while suspended in water. Buffers with trees, shrubs and other plants help to filter this water by trapping sediment and nutrients.

Shiitake Mushrooms: A Commercial Forest Farming Enterprise

Helping landowners care for their forests and strengthen local economies is an important goal of the U.S. Forest Service, USDA National Agroforestry Center and their partnering organizations.

According to Ken Mudge of Cornell University, any farmer with a woodlot and the drive to diversify should consider forest-cultivated shiitake mushrooms. They are well suited to the increasing demand for locally produced, healthy foods.

With a retail price of $12 to $20 per pound, the demand for shiitakes is considerable throughout the Northeast. As an added benefit, growing mushrooms encourages landowners to learn more about managing their forests.

Using Agroforestry to Help Pollinators Help You

Today, farms in the U.S. are larger and have less nearby habitat to support bees than in the past, yet the need for pollinators in rural landscapes has never been greater. In light of concerns over pollinator declines, a Memorandum was released by President Obama on June 20, 2014, Creating a Federal Strategy to Promote the Health of Pollinators. Since the release of this Memorandum, USDA agencies have been taking additional steps to support pollinators.

One question many people are asking is: how can we incorporate more pollinator habitat into our communities, agricultural lands, and forests?

Virginia Is for Lovers - and Silvopasture

Throughout his life, Chris Fields-Johnson has been keenly aware of the need to preserve the natural landscapes, which provide us with clean air to breathe, water to drink and food to eat. As a graduate student of soil science at Virginia State and Polytechnic University, a forestry undergraduate, a student of Tom Brown, Jr.’s Tracker School and a former employee of the Virginia Department of Forestry, he also knows much of the science behind soil restoration and forestry. These experiences have given him a strong desire to turn his knowledge into action by managing land in the most beneficial way possible.

To make this dream a reality, he began converting a 250-acre loblolly pine plantation in Scottsville, Virginia., into a goat and sheep silvopasture system that resembles a pine savanna landscape. Silvopasture combines trees with forage and livestock production. The trees are managed for high-value sawlogs and, at the same time, provide shade and shelter for livestock and forage, reducing livestock stress and sometimes improving forage quality. Fields-Johnson and friends have spent many weekends thinning and pruning trees by hand, conducting controlled burns, fighting invasive plants and experimenting with forage establishment while they also learn how to raise goats and sheep.
