Edible Ecosystems Emerging
Food Forestry for the 21st Century
9-Day Forest Garden Design Intensive
October 16 – 25, 2026
In this nine-day intensive course, you will dig deeply into the vision, theory, and practice of designing wholesome, dynamic, and resilient edible ecosystems using temperate deciduous forests as models.
Dig Deep Into Forest Garden Design
With Dave Jacke, Author of Edible Forest Gardens

Forest ecosystems hold powerful lessons for us – modeling qualities we can bring into our culture, agriculture, and horticulture to create systems that thrive for generations:
- They maintain, renew, fertilize, and propagate themselves without human inputs.
- They build, store, and conserve clean air, clean water, nutrients, soil quality, and biodiversity.
- They exhibit stability, resilience, and adaptability.
These qualities emerge from the dynamics of the forest as a whole system, not from any one or more of the elements that comprise the forest alone. To design productive edible ecosystems that express these same qualities, we must understand ecological principles and forest structures, functions, patterns, and processes, and use this knowledge wisely.
In this nine-day intensive course, you will dig deeply into the vision, theory, and practice of designing wholesome, dynamic, and resilient edible ecosystems using temperate deciduous forests as models.
Dave Jacke and his team will offer creative experiential classes, lectures, site walks and design exercises to help you understand how the architecture, social structure, underground economics, and successional processes of natural forests apply to the design of edible ecosystems of all kinds.
You’ll learn a variety of ecological design processes while designing a range of food-producing ecosystems at Horn Farm Center. Design projects could include designing forest gardens for: urban or suburban homesteads, or farm-scale (2 to 100 acres). We’ll also engage with issues of garden management, economics, and the deep paradigmatic shifts required to succeed at co-creating “humanatural” landscapes and cultures.
You will leave inspired and empowered to design food forests at home for yourself, and your friends, neighbors, and clients.

Program Glimpses:





Who is this Program For?
We all have what it takes to be ecological designers. The ability to design lives in all of us, and nature lives in and through us all. Practicing ecological design can heal us and the land.
Anyone eager to touch the soil, expand their perspective, and transform land into a dynamic edible ecosystem will find their fit in this program. From personal enrichment to professional application, the skills you’ll learn are versatile, transferable, and perennial.
The design philosophies and processes covered in this course can apply almost anywhere. Those who will find this experience especially useful are folks based in the US Mid-Atlantic, Northeast, Midwest, and Eastern Canada.
- Landowners: cultivate a backyard food forest to feed yourself and your family, increasing food security and quality, beauty, and earth-wise living.
- Farmers (aspiring and active): gain experience in agroforestry and food forest design to diversify and enrich your business.
- Landscape professionals (aspiring and active): learn more about edible foodscapes for residential and public contexts, and build your resume as a consultant, planner, or practitioner.
- Community changemakers: improve food access and community well-being through applying food forest models to public spaces that need it most.
- Landless earth tenders: explore edible landscaping hands-on while meeting others who share your passion for regenerative living.

Meet the Classroom:
The Horn Farm Center

The Horn Farm Center comprises 186 acres of distinct landscapes. Together, these landscapes reflect the legacies of human activity in the Lower Susquehanna Region, alongside possibilities for a regenerative future.
Recovering second-growth forests and mid-successional meadows accompany large acreages of commodity cropland, which are managed regeneratively by neighboring farmers. Historic activities on the land–representing over 150 years of European-style faming–include livestock grazing, cereal grain production, orchards, and even localized mining for iron ore.
In the early 2000s, community members rallied together to save the Horn Farm from industrial development. This marked the farm’s transition to a nonprofit, with a focus on agricultural education. Since these humble beginnings, the Horn Farm Center’s focus has extended beyond gardening and agriculture, embracing ecological land stewardship in all its forms. Over 30 acres of the land today consists of demonstration and experimentation spaces for regenerative agriculture, agroforestry, and ecological restoration. These regenerative approaches are made possible by the farm’s official preservation under a conservation easement with the York County Farm and Natural Lands Trust, secured in 2016.
People today can come to the Horn Farm for a variety of experiences. These include classes, service learning workdays, and special events like the York County Pawpaw Festival. The land is a living classroom for deepening connection and learning how to live regeneratively; it’s a space that combines gardening and agroforestry, ecological restoration, foraging, natural crafts, ancestral skills, and more. While the scars of history remain–from eroded waterways to struggling biodiversity–the farm presents the possibility of rekindling our roles as productive members of the ecosystem.
Geographically, the Horn Farm is located just west of the Lower Susquehanna Riverlands, a conservation landscape recognized by the state of Pennsylvania. It is firmly nestled in Pennsylvania’s Piedmont Province; its runoff drains to the Susquehanna River and Chesapeake Bay. The farm is also at the crossroads of population centers linked by the busy cooridors of Route 30 and Interstate 83. It is 10 miles east of York, PA; 20 miles west of Lancaster, PA; 30 miles south of Harrisburg, PA; and 60 miles north of Baltimore, MD.
