Native Grassland Restoration

What It Is

Native grassland restoration is the conversion of land dominated by introduced cool-season grasses — tall fescue, Bermudagrass — to diverse communities of native warm-season grasses and wildflowers. Native grasslands are among the most imperiled ecosystems in North America, reduced to approximately 2% of their historical extent in the Cumberland Plateau region.

Native warm-season grasslands evolved over thousands of years in relationship with fire, large herbivores, and diverse native plant communities. They support wildlife populations that simply cannot survive in fescue monocultures.

Why It Matters

Introduced cool-season grasses like tall fescue crowd out native plants, provide poor wildlife cover and food, and have shallow root systems that contribute to runoff and erosion. The contrast with native warm-season grasses is striking:

• Root depth: Native warm-season grasses have roots 6–10+ feet deep versus approximately 6 inches for fescue — dramatically improving water infiltration and drought resilience
• Wildlife value: Bobwhite quail, grasshopper sparrow, Henslow’s sparrow, meadowlark, and loggerhead shrike all require the structure and plant diversity of native grasslands — not fescue
• Pollinator support: Native wildflower components provide food for bees, butterflies, and other pollinators
• Forage quality: Native warm-season grasses can match or exceed fescue productivity for livestock while supporting wildlife simultaneously

How It’s Done

Site preparation (critical step):

• Kill existing vegetation with glyphosate — multiple applications (spring + fall) usually needed
• Light disking to prepare seedbed; avoid deep tillage that brings weed seeds to the surface
• No-till drilling into dead sod is the preferred seeding method
• For heavy fescue stands, an intermediate year of annual-grass cover crop may be needed before final seeding

Key native warm-season grasses:

• Big bluestem (Andropogon gerardii) — tall grass, high biomass
• Little bluestem (Schizachyrium scoparium) — most common bunch grass, excellent quail cover
• Indiangrass (Sorghastrum nutans) — tall, distinctive seed heads
• Switchgrass (Panicum virgatum) — good wildlife cover
• Eastern gamagrass (Tripsacum dactyloides) — excellent forage, bottomlands
• Sideoats grama (Bouteloua curtipendula) — shorter, good for thin soils

Native wildflowers (forbs) to include:

• Black-eyed Susan, purple coneflower, butterfly milkweed, wild bergamot, partridge pea, blazing stars, goldenrods

Seeding: Best window is late fall (dormant seeding) or early spring. Native grass seeding rate: 6–10 PLS lbs/acre. Do NOT fertilize native plantings — fertilization favors weedy competition. Use local seed sources where possible.

Expected Outcomes

• Year 1: Annual weeds dominate; native grass seedlings emerging — looks rough, this is normal
• Year 2: Grasses becoming visible; mow high (8–12 inches) to reduce weed competition
• Year 3: Native grasses dominating; first prescribed burn can be introduced
• Years 4–5: Full stand establishment with diverse wildflowers appearing
• Patience is essential — native grasslands take 3–5 years to establish
