  • Tree Crops and Agroforestry Whole-systems Regeneration Through Perennial Agriculture Connor Stedman – Gaia Northeast Thanks to: M. Kat Anderson, Dave Jacke, Ethan Roland, Jon Young
  •  
  • What is Agroforestry?
    • Agroforestry (AF) is land use integrating trees and/or tree crops with other types of agriculture.
    • The three I’s:
      • Intentional
      • Intensive
      • Interconnected
    • The “Rule of 3”: An AF system must have at least 3 “layers” or managed functional elements.
  • The Roots – Indigenous AF Worldwide
  • Tropical Agroforestry
  • Tropical Agroforestry
    • Read 1491 by Charles Mann. Current Amazonian rainforest diversity is a result of thousands of years of native agroforestry.

    • Hawai’ian Ahupua’a – whole-watershed management from mountain to sea, cared for by extended family networks.
  • Temperate & Mediterranean Agroforestry
    • (Wherever acorns are found.)
  • Balanoculture
  • Cork Oak Savanna
  • Tending the Wild Across North America
  • Tending the Wild Across North America
    • M. Kat Anderson spent 17 years interviewing native elders from around California.
  • Tending the Wild Across North America
    • M. Kat Anderson spent 17 years interviewing native elders from around California.
    • Their stories illustrate whole-ecosystem caretaking based on agroforestry and managing wild plant and animal populations for harvest.

    • M. Kat Anderson spent 17 years interviewing native elders from around California.
    • Their stories illustrate whole-ecosystem caretaking based on agroforestry and managing wild plant and animal populations for harvest.
    • Analogous patterns are found in the history (and sometimes present day) of every inhabited ecosystem in North America.
  • Soaproot – Chlorogalum spp.
    • A “wild” plant physiologically
    • adapted to human harvesting
    • and use.
  • Some Paradigm Shifts
    • Don’t just plant and harvest crops – manage and participate in the ecosystems that support staple crops in abundance.
  • Some Paradigm Shifts
    • Don’t just plant and harvest crops – manage and participate in the ecosystems that support staple crops in abundance.
    • Traditional land use patterns have resulted in heritage ecosystems , with humans as keystone species within those ecosystems.

    • With regenerative land use practices, human economic activities increase ecosystem health.

    • Whole Ecosystem Management
  • So…. What does all this mean in the Northeast US?
  • Northeast US Forest Characteristics
    • Temperate forest ecosystem; 40+ inches of rain distributed evenly through the year.
  • Northeast US Forest Characteristics
    • Temperate forest ecosystem; 40+ inches of rain distributed evenly through the year.
    • Rainfall exceeding evaporation + heavy winter snowfalls = high levels of spring mineral leaching from topsoil.
  • Northeast US Forest Characteristics
    • Temperate forest ecosystem; 40+ inches of rain distributed evenly through the year.
    • Rainfall exceeding evaporation + heavy winter snowfalls = high levels of spring mineral leaching from topsoil.
    • Most forests are under 100 years old. Old-growth very rare and extremely fragmented.

    • Most forests are under 100 years old. Old-growth very rare and extremely fragmented.
    • Coastal & intervale prairies and savannas almost completely gone – huge loss of diverse early-succession habitats.
