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 Histosols, 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

Linear Meadow sites are limited in extent in the southern region of MLRA 57, and typically occur on moraines, lake plains and outwash plain in lower footslope and toeslope hillslope positions, bottomlands, and linear upland drainageways. Soils can vary widely in texture and are mostly mollisols with dark organic-enriched upper horizons. These sites are typically poorly and very poorly drained soils with depth to gray and or rust colored redoximorphic features or depth to seasonal high water-table ranges from 0 to 25 centimeters. These sites often support a prairie ecosystem consisting of mix grass species adapted to seasonal high water tables.

Ecological dynamics

Linear meadow sites consist of a meadow community of mixed grasses and sedges that are influenced by seasonally high water tables. During wet weather cycles, community 1.1 can become more marsh like and creates a sedge dominated community with willow and dogwood. It is possible to go back to the reference community with prolonged draught from community 1.2. State 2 consists of an invaded state where invasive grasses such as smooth brome and reed canarygrass have taken hold due to lack of grazing, overgrazing, or long periods of no fire. It is expected there is a woody state, consisting of heavier shrub and tree populations that occur on this site as well, but it is not documented well enough to be included at this time. Some of these sites may be turned into agricultural land.

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.
