Tamed Grassland

Planted or Tame Grassland

Area: unknown, estimate 2-5 million acres

Description and Overall Condition: This landscape component includes land that had been converted to cropland and re-planted to hayland, tame or native grasses. Hayland constitutes approximately 5% of the state. Planted alfalfa is the most common hay crop. Hay may be cut up to four or five times throughout the growing season. Haying earlier than July 15, or before nesting birds have fledged, can result in bird mortality from the machinery. The Conservation Reserve Program (CRP) was established in the 1985 Farm Bill as a tool for producers to conserve marginal soil by retiring cropland from production for 10 to 15 years. The CRP program provides income for producers and delivers unprecedented landscape scale wildlife habitat and conservation of soil and water. Larger tracts of CRP, particularly in juxtaposition with other existing native or planted grassland, are more attractive and more productive than smaller tracts of CRP. These larger tracts, in concert with surrounding landscape features, are a focus area of this landscape component. CRP is generally left idle although managed and emergency haying and grazing of CRP may be allowed. Producers can hay or graze CRP once every three years, keeping outside of the primary nesting season defined as April 15-August 1. The number of acres of hayed and grazed CRP has and continues to increase as a result, which can be beneficial to many wildlife species. More than half of the CRP contracts have expired since 2007 and obstacles for reauthorization of the program limits new contracts. The loss of CRP on the North Dakota landscape will be detrimental to wildlife populations. Tame grasslands are widespread throughout the state on wildlife management areas, waterfowl production areas, and other publicly owned land.
