About

Forest farming combines aspects of forestry and small-scale farming through intentionally managing crops through multi-story cropping. Benefits of forest farming include increased diversity, improved habitat, and improved soil health1 2. Forest farming requires intentional management, including the use of vertical space, and provides an avenue to produce non-timber forest products. Common forest farming products can be sold for medicinal, culinary, or ornamental use. Depending on the goals of the producer, canopy shade levels can be adjusted through changes in species composition and forest structure. Forest farming can vary in management intensity, with three recognized methods of management: wood grown, wild-simulated, and managed wild populations.

Key aspects and considerations:

  • Consider interactions between plants and microclimate.
  • Choose trees with low to moderate root and crown spread.
  • Select crops that are tolerant of shade.
  • Ensure trees are planted or managed with enough spacing to allow light for understory canopy growth.
  • Select sites that are suitable for desired crops.
  • Ensure proper documentation when growing protected species.
  • Determine appropriate density and understory structure.
  • Consider slope aspect when determining where to plant.
  • Forest farming maintains cultural traditions and recreational hobbies.

Benefits and Limitations

ACRE CategoryBenefitsLimitations
Soil Health
  • Improves forest composition and enhances stand health3, which may improve carbon storage and soil health.

  • Combining trees with intentional understory vegetation increases organic matter.

  • May increase localized soil compaction due to harvest.
Water Management
  • Understory crops may compete for soil moisture during dry periods.
Nutrient Management
  • Tree litter from the multi-story system improves nutrient cycling while requiring fewer inputs.
  • N/A
Agricultural Production
  • Helps meet demand for specialty products and plants.

  • Staggers production across seasons.

  • Improves pest and invasive species management with active forest management.

  • Reduces harvest pressure on wild plant populations4.

  • Protects from wildfire by thinning and managing understory vegetation7.

  • Limited suitable understory crops for low-light forest farming conditions.

  • Requires active management, including managing the interactions between the understory and overstory environment.

  • Management may conflict with labor, time, and money demand of other crops5.

  • Requires long-term investment.

  • Requires more information on best management practices for non-timber forest production8 9.

Biodiversity and Wildlife
  • Understory crops increase species diversity4.

  • Multistory systems provide wildlife habitat to a range of species.

  • N/A
GHG Emission
  • Incorporating trees into the landscape increases carbon storage above and belowground.

  • Often requires few inputs, releasing less N2O than conventionally fertilized cropping systems.

  • Increases CO2 emissions if a forest is thinned for forest farming6.

  • Heavy thinning and high-disturbance management minimize GHG reductions and should be avoided6.

Economics
  • Generates alternative or supplemental income.

  • Non-timber products provide short-term income, while trees may provide high-value timber.

  • Produces high-value crops, such as ginseng and shiitake mushrooms.

  • Federal and state funding opportunities provide cost-share programs.

Impact on Agricultural Resilience

  • Forest farming modifies the microclimate for lower canopy plants, assisting with temperature regulation, humidity control, and water use efficiency, which makes the system more resilient to changing conditions7. Microclimate modification can be especially important under trends of increasing extreme heat and variable rainfall.

Regional Applicability

  • Generally, forest farming is well suited for regions or states that already contain forested land. For example, forest farming may be well suited in Kentucky, as forestland is often maintained for wildlife habitat and recreation.
  • Forest farming is not widely adopted in the region, though there are opportunities in parts of the Midwest, such as Wisconsin, where ginseng can grow under low light conditions. Additionally, depending on the management, maple syrup production can be a strong candidate for forest farming relevant to the Midwest region. Maple syrup production has grown steadily in the Midwest, increasing by over 200% from 2000 to 2013 in Ohio, Michigan, and Wisconsin10, making it a strong candidate for forest farming systems.

Case Studies

  • At the Lawrence Community Orchard in Lawrence, Kansas, volunteers and community members plant and manage over 100 edible woody perennials, including fruit and nut trees. Skyler Adamson, the project coordinator, describes some of the justifications for forest farming: "Communities should be producing food, and perennials happen to be a lower-cost and lower-labor way to do that."
  • In Wisconsin, Mark Shepard of New Forest Farm implements a range of agroforestry practices, including forest farming, where he produces chestnuts, hazelnuts, apples, asparagus, and pigs. Mark has spent decades increasing wildlife and improving organic matter on his farm, stating, "Agroforestry has the answers to so many challenges. We can solve them with programs we already have in place, and we can do it at a profit."
  • In Amesville, OH, John Wood practices forest farming for maple syrup production. With 8 acres, John is able to sell directly to producers. John recommends learning from peers in your area if you're considering forest farming.
