MLRA notes

Major Land Resource Area (MLRA): 057X–Northern Minnesota Gray Drift

The Northern Minnesota Gray Drift (57) is located within the Northern Lakes Forest and Forage Region. This area is entirely in north-central Minnesota and makes up about 9,785 square miles (Figure 1). The entire area is covered by Wisconsin-age glacial drift. The glacial deposits are from four major ice lobes-Des Moines, Rainy, Superior, and Wadena. The landscape developed through a series of glaciations and the subsequent retreating and wasting of the ice sheets, which resulted in a complex pattern of moraines, outwash plains, drumlins, lake plains and drainages. Lakes, ponds and marshes are common. The thickness of the glacial till ranges from 90 to 185 meters. Some areas of these deposits are overlain by outwash or lacustrine sediments. Some depressional areas have an accumulation of organic matter. The organic deposits are more than 2.5meters thick in some areas. Elevation ranges from 300 to 500 meters across the area. (USDA-NRCS 2006)

The dominant soil orders in this MLRA are Alfisols, Entisols, and Histisols, with some Mollisols in the westernmost part of the area. The soils in the area have a frigid soil temperature regime; aquic or udic soil moisture regime, and mixed mineralogy. Their natural drainage class is related to landscape position. In general, the Alfisols formed in till on moraines, Entisols formed in outwash on moraines and outwash plains, and Histosols formed in organic material over outwash or till on moraines or outwash plains. (USDA-NRCS 2006)

Ecological site concept

Associated sites

F057XY017MN	Steep Loamy Upland Forest These sites occur on shoulders and backslope hillslope positions with slopes greater than 15 percent on outwash plains and moraines. These sites typically exist on soils with sandy textures of sand, coarse sand, loamy sand, loamy coarse sand, fine sand, or loamy fine sand within a depth of 50 centimeters. The underlying material is generally coarse textured and generally has 0 to 35 percent rock fragments, but areas of sand capped glacial till can be included.
F057XY015MN	Wet Mixed Forest These sites occur on footslope and toeslope hillslope positions, drainageways surrounded by uplands or on the edge of uplands grading to very poorly drained peatland soils. These sites typically exist on loamy and occasionally sandy moraines and till plains. Parent material is calcareous fine to loamy textured glacial till, stratified material and occasionally sandy.

Climatic features

In general, MLRA 57 has cold winters and warm summers. About 65 percent of the annual precipitation falls as rain during the 5-month growing season (May through September), and an additional 18 percent falls as snow. The freeze-free period averages 150 days and ranges from 120 to 175 days.

Soil features

The central concept soil series are Abbeylake, Clearriver, Eagleview and Zimmerman but other series are included. These sites typically exist on soils with coarser textures of sand, coarse sand, loamy sand, loamy coarse sand, fine sand, or loamy fine sand within a depth of 50 centimeters. The underlying material is generally coarse textured and generally has 0 to 35 percent rock fragments, but areas of sand capped glacial till can be included. Soils are moderately well to excessively drained with rust and gray redoximorphic features and or depth to seasonal water table between 50 to greater than 150 centimeters. In some areas the soil surface color is somewhat dark to very dark in the upper 25cm because of incorporated organic matter, which indicates that these site were formerly occupied by deciduous woodlands and prairies.

Rangeland health reference sheet

Interpreting Indicators of Rangeland Health is a qualitative assessment protocol used to determine ecosystem condition based on benchmark characteristics described in the Reference Sheet. A suite of 17 (or more) indicators are typically considered in an assessment. The ecological site(s) representative of an assessment location must be known prior to applying the protocol and must be verified based on soils and climate. Current plant community cannot be used to identify the ecological site.
