General information

Provisional. A provisional ecological site description has undergone quality control and quality assurance review. It contains a working state and transition model and enough information to identify the ecological site.

MLRA notes

Major Land Resource Area (MLRA): 088X–Northern Minnesota Glacial Lake Basins

MLRA 88 consists of the lake beds of glacial Lakes Agassiz, Upham, and Aitkin. These vast glacial lake beds were formed by meltwaters associated with the last glaciation of the Wisconsin age. The large, flat, wet landscapes are filled with lacustrine lake sediments, wave-washed glacial till, and vast expanses of organic soils. This area is entirely in Minnesota and makes up about 11,590 square miles (30,019 square kilometers).

The western boundary of MLRA 88 with MLRA 56B is gradual. MLRA 56B is a portion of the Red River Valley that was formed by glacial Lake Agassiz and is dominantly prairie. The southern boundary of MLRA 88 with MLRA 57 consists of distinct moraines that formed from the glacial drift sediments of Late Wisconsin age. The eastern and southeastern boundaries are with portions of MLRAs 90A and 93A. These MLRAs are in a distinct glaciated region of sediments of the Rainy and Superior Lobes, and much of MLRA 93A is bedrock controlled (USDA-Ag Handbook 296, 2022).

Climatic features

The average annual precipitation is 25 to 28 inches (635 to 711 millimeters). Most of the rainfall comes from convective thunderstorms during the growing season. Snowfall generally occurs from October through April. The average annual temperature is 43 to 46 degrees F (6 to 8 degrees C). The mean frost free period ranges from 83 to 110 days, with the mean freeze-free period ranging from 117 to 135 days.

Soil features

Soils in this site are coarse textured, ranging from loamy find sands to very fine sandy loams. These soils developed from glaciolacustrine, outwash, and eolian sand parent material.

Soils in the Moist Sandy Mixed Forest fall within the Alfisol, Entisol, Inceptisol, and Mollisol orders. These soils can be further classified as Oxyaquic Hapludalfs, Aquic Udipsamments, Aeric Endoaquepts, and Aeric Calciaquolls. Soil series within this site include: Meehan, Redby, Barber, Cowhorn, Soderville, and Ulen.

State 1
Reference State

The reference state is a coniferous woodland composed of pine and spruce with a mix of hardwood species such as aspen and paper birch. Canopy cover is variable and ranges from patchy to continuous. Dominant canopy species include jack pine, black spruce, red pine, and in some cases, white pine.

Dominant plant species

jack pine (Pinus banksiana), tree
black spruce (Picea mariana), tree
red pine (Pinus resinosa), tree
serviceberry (Amelanchier), shrub
lowbush blueberry (Vaccinium angustifolium), shrub
northern bush honeysuckle (Diervilla lonicera), shrub
Canada mayflower (Maianthemum canadense), other herbaceous
bunchberry dogwood (Cornus canadensis), other herbaceous
twinflower (Linnaea borealis), other herbaceous

Community 1.1
Mature Mixed Forest Community

This is a mature (95+ years) mixed-canopy woodland. Black spruce is dominant mixed with jack pine, paper birch, white pine, and balsam fir. (MN DNR, 2005).

Dominant plant species

jack pine (Pinus banksiana), tree
paper birch (Betula papyrifera var. papyrifera), tree
eastern white pine (Pinus strobus), tree
balsam fir (Abies balsamea var. balsamea), tree

Community 1.2
Early Successional Forest

This community (0-55 years) is characterized by a young woodland dominated by jack pine. Hardwoods, such as quaking aspen and paper birch, are common. (MN DNR, 2005).

Dominant plant species

jack pine (Pinus banksiana), tree
quaking aspen (Populus tremuloides), tree
paper birch (Betula papyrifera), tree

Community 1.3
Mid Successional Forest

This mixed canopy transitional community (55-95 years) is noted for an increase in red pine and paper birch and a decline in jack pine and quaking aspen. (MN DNR, 2005)

Dominant plant species

red pine (Pinus resinosa), tree
paper birch (Betula papyrifera var. papyrifera), tree

Pathway 1.1A
Community 1.1 to 1.2

Disturbance from fire, windthrow, or other factors that removes the canopy layer.

Pathway 1.2A
Community 1.2 to 1.3

Time and natural succession will transition the 1.2 community to the 1.3 community in the absence of any large disturbances.

Pathway 1.3A
Community 1.3 to 1.1

In the absence of large disturbances, time and natural succession will transition the community to a mature woodland.

Pathway 1.3B
Community 1.3 to 1.2

A large disturbance will transition the community back to an earlier successional stage.

State 2
Disturbed State

This is a woodland state characterized by anthropogenic disturbances such as logging. Human activities are often a conduit for the introduction and spread of invasive species. The type, severity, and duration of the disturbance will perpetuate variability in the early successional plant community. Seed sources and management activities will also influence plant regeneration. Future field study is needed to develop a more detailed and diagnostic list of plant species for this state.

Dominant plant species

quaking aspen (Populus tremuloides), tree
paper birch (Betula papyrifera), tree
jack pine (Pinus banksiana), tree
serviceberry (Amelanchier), shrub

Community 2.1
Logged Community

Removal of canopy trees for timber harvest results a highly disturbed understory. Shrubs often initially dominate post-logging. The type and severity of disturbance, available seed sources, and any associated management inputs will determine the plant community on site.

Dominant plant species

serviceberry (Amelanchier), shrub

Community 2.2
Invaded Community

This community is characterized by the presence of non-native plant species. Numerous tree, shrub and ground layer invasive species are possible. Human activities (logging, development, recreation) can introduce seeds to a site. Without management intervention, these species can alter the natural composition of the plant community.

Dominant plant species

common buckthorn (Rhamnus cathartica), shrub
Canada thistle (Cirsium arvense), other herbaceous

Pathway 2.1A
Community 2.1 to 2.2

Activities such as logging may introduce invasive plant species.

Pathway 2.2A
Community 2.2 to 2.1

Management inputs to successfully eradicate invasive plants on site.

Transition T1A
State 1 to 2

Disturbance of site through anthropogenic activities such as road building, dam construction, and logging.

Restoration pathway R2A
State 2 to 1

Restoration of each site will require a plan unique to the current site conditions. Timber stand improvement activities and/or invasive species eradication may be needed.

Inventory data references

This is a provisional ecological site, and as such no field plots were inventoried for this project. A review of the scientific literature and expert opinion was used to develop the plant communities and ecological dynamics contained within the state and transition model. Future field verification is needed to refine the plant communities and ecological dynamics described in this ecological site description.

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.
