Agroforestry blends traditional ecological knowledge with modern agriculture, integrating trees, crops, and livestock on the same land. This approach enhances sustainability and productivity in Native communities, drawing on centuries-old practices.

Forest gardening mimics natural ecosystems to create low-maintenance food systems. It uses layered vegetation structures and promotes biodiversity, incorporating Native American horticultural techniques with permaculture concepts for resilient, productive landscapes.

Agroforestry systems

• Encompasses various land management approaches combining trees with crops or livestock
• Adapts to different ecological zones and cultural contexts
• Provides multiple economic and environmental benefits to Native communities

Alley cropping

• Involves planting rows of trees or shrubs interspersed with agricultural crops
• Trees provide windbreaks, improve soil fertility, and offer additional income sources
• Crops benefit from improved microclimate and nutrient cycling
• Can include both annual and perennial crops (corn, beans, squash between rows of fruit trees)
• Allows for mechanized cultivation while maintaining tree cover

Silvopasture

• Integrates trees, forage plants, and livestock in a mutually beneficial system
• Trees provide shade, wind protection, and supplemental feed for animals
• Livestock contribute to nutrient cycling and understory management
• Improves animal welfare and productivity in grazing systems
• Can incorporate culturally significant tree species (oak savannas)

Riparian buffer strips

• Establishes trees and shrubs along waterways to protect water quality
• Reduces soil erosion and filters agricultural runoff
• Provides habitat for aquatic and terrestrial species
• Stabilizes stream banks and moderates water temperatures
• Can include harvestable products like berries or biomass for energy

Environmental benefits

• Enhances ecosystem services in agricultural landscapes
• Contributes to climate change mitigation and adaptation strategies
• Supports conservation of biodiversity and natural resources

Soil conservation

• Reduces erosion through increased ground cover and root systems
• Improves soil structure and water infiltration capacity
