Background information. In the late 1800s through the early 1900s, nearly all of the area that is now the Crab Orchard National Wildlife Refuge (Crab Orchard NWR) was either logged for timber or cleared and converted to other uses, particularly agriculture. By the 1930s, soils in the area were depleted and severely eroded. Additional clearing and development ensued with the establishment of the Illinois Ordnance Plant during World War II. In 2014, as part of the effort to restore Crab Orchard NWR lands to benefit wildlife, the refuge undertook the Hampton native prairie restoration project to convert a 62-acre nonnative cool-season hay field into a native warm-season grassland. The primary benefit of this restoration...
The Agassiz Beach Ridges landscape is located in the Red River watershed of northwestern Minnesota and falls and is within the larger Prairie Pothole Region (PPR). The PPR has been identified as being responsible for producing 50–80 percent of the continent’s waterfowl while accounting for only 10% of the available breeding habitat. It is estimated that less than 1% of Minnesota’s historic native prairie remains intact, with much of the remnant prairie scattered about in small clusters. Restoration of key sites within this landscape has been identified as the most important strategy to create a contiguous expanse of prairie/wetland mosaic and improve the ecological functioning of these systems. In the fall of...
An increase in land conversion from grassland to cropland in the United States has attracted attention in recent years. According to Claassen et al. (2011a), grassland to cropland conversion is concentrated in the Northern Plains, including Kansas, Nebraska, North Dakota and South Dakota, which encompasses only 18% of U.S. rangeland but accounted for 57 percent of U.S. rangeland to cropland conversion during the study period of 1997 to 2007. Focusing on land cover data in the Western Corn Belt, Wright and Wimberly (2013) also pointed out that grassland conversion was mostly concentrated in the Dakotas, east of the Missouri River and between 2006 and 2011.
