Northern Prairie Wildlife Research Center
|46f. End Moraine Complex||Level IV Ecoregion|
|The Northern Glaciated Plains
ecoregion is characterized by a flat to gently rolling landscape
composed of glacial drift. The subhumid conditions foster a grassland
transitional between the tall and shortgrass prairie. High concentrations
of temporary and seasonal wetlands create favorable conditions for duck
nesting and migration. Though the till soil is very fertile, agricultural
success is subject to annual climatic fluctuations.
The End Moraine Complex is a concentration of glacial features in east central North Dakota. Blue Mountain and Devils Lake Mountain are composed of blocks of surficial material scraped off and thrust up by the continental glacier at the south end of the Devils Lake basin. In the western part of the ecoregion, patches of stagnation moraine similar to the Missouri Coteau (42a) have high wetland densities. On the moraines south of Devils Lake basin, favorable precipitation, aspect, and slightly higher elevations result in wooded lake margins and morainal ridges.
