Savanna ecosystems blend the best of prairies and woodlands—scattered oak trees create dappled shade over a diverse understory of grasses, wildflowers, and shrubs. Historically maintained by fire, savannas are transition zones with high biodiversity and unique plant communities adapted to partial sun and periodic disturbance. Savanna plants tolerate a range of light conditions and often feature deep roots and fire-adapted traits. This archetype supports oak-specialist insects (which feed more bird species than any other tree genus), ground-nesting birds, and shade-tolerant pollinators. Ideal for sites with partial sun, existing trees, or gardeners seeking to recreate this rare and beautiful Midwest ecosystem.
