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).

Ecological site concept

This site is a dry jack pine-red pine woodland and located on outwash plains and moraines. Soils are course textured, well drained to excessively drained, and have a low available water capacity. Historically, fire was a common disturbance that influenced plant community composition.

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 86 to 110 days, with the mean freeze-free period ranging from 117 to 135 days.

Soil features

Soils in this site are coarse textured, moderately well-drained, and very deep. These soils formed in glaciolacustrine or glaciofluvial deposits and eolian sand parent material. Soils in this site have relatively low available water capacity.

Soil series in the Dry Sandy Upland Coniferous Forest ecological site fall within the Alfisol, Entisol, and Mollisol orders. These soils can be further classified as Aquic Hapludalfs, Aquic Udipsamments, Lamellic Udipsamments, Oxyaquic Udipsamments, Typic Udipsamments, Aeric Calciaquolls, Entic Hapludolls, and Oxyaquic Hapludolls.

Ecological dynamics

This site is a dry jack pine-birch woodland. Fire was a historical disturbance that influenced plant species composition. Young woodlands post-fire are dominated by jack pine and paper birch. Mature woodlands are pine dominated with an understory variability dependent upon the fire regime. (MN DNR, 2005)

State 1
Reference State

This is a dry jack pine - red pine woodland on course textured soils. Sites occur on undulating sandy outwash plains, lake plains, and moraines. Historically, the site was influenced by fire events which occurred approximately every 40-50 years. (MN DNR, 2005).

Dominant plant species

jack pine (Pinus banksiana), tree
red pine (Pinus resinosa), tree
eastern white pine (Pinus strobus), tree
white spruce (Picea glauca), tree
paper birch (Betula papyrifera), tree
quaking aspen (Populus tremuloides), tree
lowbush blueberry (Vaccinium angustifolium), shrub
serviceberry (Amelanchier), shrub
roughleaf ricegrass (Oryzopsis asperifolia), grass
Canada mayflower (Maianthemum canadense), other herbaceous

Community 1.1
Mature Dry Pine Community

This community is characterized by a lack of severe disturbance for over 75 years. The plant community composition is dominated by red pine. Jack pine, white pine, white spruce, and paper birch are also present. (MN DNR, 2005)

Dominant plant species

red pine (Pinus resinosa), tree

Community 1.2
Early Successional Dry Pine Community

This young woodland community is 0-55 years of age and generally dominated by jack pine. Red pine, quaking aspen, paper birch, and white pine are also on site. (MN DNR, 2005)

Dominant plant species

jack pine (Pinus banksiana), tree
red pine (Pinus resinosa), tree
quaking aspen (Populus tremuloides), tree
paper birch (Betula papyrifera), tree
eastern white pine (Pinus strobus), tree

Community 1.3
Mid Successional Dry Pine Community

The mid successional woodland stage (55-75 years of age) is characterized by a decline in jack pine and an increase in red pine and white pine. (MN DNR, 2005)

Dominant plant species

red pine (Pinus resinosa), tree
eastern white pine (Pinus strobus), tree

Pathway 1.1A
Community 1.1 to 1.2

A severe disturbance, such as a catastrophic fire, will transition the reference community to an early successional community.

Pathway 1.2A
Community 1.2 to 1.3

Time and natural plant community growth will transition the site to community 1.3.

Pathway 1.3A
Community 1.3 to 1.1

Time and natural plant community succession will transition the community to a mature, established wood over 75 years of age.

Pathway 1.3B
Community 1.3 to 1.2

A severe disturbance, such as a major fire event, will transition the community back to an earlier successional stage.

State 2
Logged State

Removal of canopy species for timber harvest creates an open canopy and a highly disturbed understory. Shrubs will dominate post logging. A very dense shrub layer can impede tree regeneration. Heavy machinery are a common seed source for non-native species.

Dominant plant species

serviceberry (Amelanchier), shrub
prickly rose (Rosa acicularis), shrub
smooth rose (Rosa blanda), shrub
beaked hazelnut (Corylus cornuta), shrub
prairie willow (Salix humilis), shrub
blueberry (Vaccinium), shrub
poverty oatgrass (Danthonia spicata), grass
ricegrass (Oryzopsis), grass

Community 2.1
Logged community

With the canopy removed, the initial post-logging community will be dominated by shrubs.

Dominant plant species

serviceberry (Amelanchier), shrub
beaked hazelnut (Corylus cornuta var. cornuta), shrub
prairie willow (Salix humilis), shrub
blueberry (Vaccinium), shrub
poverty oatgrass (Danthonia spicata), grass
ricegrass (Oryzopsis), grass

Community 2.2
Invaded Community

This community is identified by the presence of non-native plant species. Heavy machinery and soil disturbance provide an opportunity for invasives to become established. The invasive species on site will depend on the seed source.

Dominant plant species

common buckthorn (Rhamnus cathartica), shrub
purple loosestrife (Lythrum salicaria), other herbaceous
Canada thistle (Cirsium arvense), other herbaceous

Pathway 2.1A
Community 2.1 to 2.2

Invasive species are introduced to the site and become established.

Pathway 2.2A
Community 2.2 to 2.1

Management inputs will be required to eradicate non-native plant species.

Transition T1A
State 1 to 2

This transition represents the removal of canopy species and severe understory disturbance.

Restoration pathway R2A
State 2 to 1

Restoration inputs, such as timber stand management activities, can transition the Logged State back to State 1.

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.
