Many tallgrass prairies and savannas are degraded from decades of fire suppression (preventing burns) or inappropriate tree planting and are in need of restoration. To help these ailing remnants, several techniques can be used including:

• regular controlled burns;
• fall mowing and thatch removal;
• shrub and tree removal;
• selective herbicide treatments on non- native plants and aggressive shrubs and trees; and
• over-seeding with appropriate native prairie grass and flower seeds.
