Resource Management

Resource Management

Refuge staff manage habitat to benefit wildlife. Refuge managers change water levels and mow and disk fields to benefit migrating waterfowl and shorebirds in the spring and fall and nesting marsh and water birds in the summer.

Moist soil plants such as smartweed, rice cutgrass, and wild millet grow during the summer months and then marsh units are flooded in the fall where waterfowl feed on the moist soil plant seeds.

Refuge personnel conduct prescribed burns to prevent invasive and woody plant growth. The tallgrass prairies consisting of big bluestem, little bluestem, Indian grass, and switchgrass have nearly vanished in the Midwest. Refuge staff members have restored some native prairie on the Loess Hills and in the wetlands.
