Mesic Prairie

State Rank: S1     Global Rank: G2   what are these ranks?

Definition

General natural community overview

Counties shaded blue have documented occurrences for Mesic Prairie in the Wisconsin Natural Heritage Inventory database.

Also called tallgrass prairie, Mesic Prairie was common historically, but is extremely rare today. This grassland community occurs on rich, moist, well-drained sites, usually on level or gently rolling glacial topography. The dominant plant is big bluestem (Andropogon gerardii). The grasses little bluestem (Andropogon scoparius), Indian grass (Sorghastrum nutans), needle grass (Hesperostipa spartea), prairie dropseed (Sporobolus heterolepis), and switch grass (Panicum virgatum) are also frequent. The forb layer is diverse in the number, size, and physiognomy of the species. Common taxa include the prairie docks (Silphium spp.), lead plant (Amorpha canescens), heath and smooth asters (Aster ericoides and A. laevis), prairie coreopsis (Coreopsis palmata), prairie sunflower (Helianthus pauciflorus), rattlesnake-master (Eryngium yuccifolium), flowering spurge (Euphorbia corollata), bee-balm (Monarda fistulosa), prairie coneflower (Ratibida pinnata), and spiderwort (Tradescantia ohioensis).

At the time of European settlement it is estimated that this type occupied over 800,000 acres in southern Wisconsin. Today less than 100 acres of intact tallgrass prairie still exists, and is associated with other prairie communities, various wetland types, and oak openings. The present rarity of this type is due to the deep, rich soils built by the extensive root systems of the prairie plants which, once discovered, were converted to some of the most productive croplands in the world.

Rare plants

The Natural Heritage Inventory has developed scores indicating the degree to which each of Wisconsin's rare plant species is associated with a particular natural community or ecological landscape. This information is similar to that found in the Wildlife Action Plan for animals. As this is a work in progress, we welcome your suggestions and feedback.

Scores: 3 = "significantly associated," 2 = "moderately associated," and 1 = "minimally associated."

Landscapes

The following Ecological Landscapes have the best opportunities to manage for Mesic Prairie, based on the Ecological Landscapes of Wisconsin Handbook.


Map of the Ecological Landscapes of Wisconsin.


Major (3 on map)
A major opportunity for sustaining the natural community in the Ecological Landscape exists, either because many significant occurrences of the natural community have been recorded in the landscape or major restoration activities are likely to be successful maintaining the community's composition, structure, and ecological function over a longer period of time.

Important (2 on map)
Although the natural community does not occur extensively or commonly in the Ecological Landscape, one to several occurrences do occur and are important in sustaining the community in the state. In some cases, important opportunities may exist because the natural community may be restricted to just one or a few Ecological Landscapes within the state and there may be a lack of opportunities elsewhere.

Present (1 on map)
The natural community occurs in the Ecological Landscape, but better management opportunities appear to exist in other parts of the state.

Threats/Actions

Wisconsin Wildlife Action Plan graphic

What are conservation actions?

Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the WWAP because lack of information can threaten our ability to successfully preserve and care for natural resources.

Considerations

The following are additional considerations for Mesic Prairie in Ecological Landscapes with opportunities for protection, restoration, and/or management. For more information, see the Wildlife Action Plan.

Southeast Glacial Plains

Relatively few remnants exist (e.g., Westport Drumlins on the north side of knolls (Dane County), Arlington Prairie (Columbia County), Empire Prairie, White River Marsh Wildlife Area (Green Lake County), and Sugar River Trail Prairie (Green County)). Most remnants are small and isolated. Prairie inventories are needed for sites near Madison in the southwest portion of the Ecological Landscape and around the southern portion of the Kettle Moraine. A few additional remnants occur in the Lake Winnebago area, in railroad rights-of-way, but structure is often altered and species diversity is diminished. Several very small occurrences have been documented in railroad rights-of-way in and around Horicon Marsh. Additional inventory may be needed in the northern part of the Ecological Landscape (Fond du Lac and Winnebago Counties). Some sites are impacted by herbicides from both ground and aerial applications.

Southern Lake Michigan Coastal

Remaining sites should be preserved where they exist (e.g., remnants at Bong Recreation Area, and limited parts of Chiwaukee Prairie Preserve in Kenosha County). Other examples are found at Kansasville Railroad Prairie and Sturtevant Mesic Prairie (Racine County) and Benedict Prairie (Kenosha County). These occurrences are all small and most occur within rights-of-way, where they are highly vulnerable to inadvertent damage or destruction.

Southwest Savanna

Few occurrences exist in this Ecological Landscape today, and most of them are small and isolated. There are, however, some good restoration opportunities, or opportunities to manage remnants within large acreages of surrogate prairie grassland within generally open landscapes. Examples include Ipswich Prairie State Natural Area (Grant and Lafayette counties), the Military Ridge Prairie Heritage Area (Iowa County), the Highway 39 Grasslands (Green County), Belmont Prairie (Lafayette County), and Stony Creek Prairie (Iowa County).

Western Coulee and Ridges

All sites are small and isolated. Past conversion to agriculture has impacted virtually all former mesic prairie in this Ecological Landscape. A few small, degraded examples of this type still exist. There is some potential that additional inventory efforts could yield undiscovered remnants, but none of these would be large. Restoration opportunities should focus on areas where there are extensive surrogate prairie grasslands, other prairie or savanna remnants, or areas where open wetlands are common.

Western Prairie

Historically, this Ecological Landscape was a major area for tallgrass prairie communities, including mesic prairie on the uplands. This is the only landscape in Wisconsin where prairie potholes were characteristic landscape features. Very few remnants remain. In most areas, the land was plowed right down to the edge of the potholes. The few existing remnants, all of which are small should be preserved and buffered with compatible community types such as surrogate prairie grassland. Potholes should also be incorporated into these complexes. Large-scale constructionrestoration of sites is needed. Grassland sites in this landscape should be surveyed and assessed to identify unplowed areas of former prairie with high restoration potential. Examples of mesic prairie include Roberts Railroad Prairie and the Hammond Cemetery Prairie (both in St. Croix County). The best restoration opportunities are probably associated with the state and federal waterfowl production areas, where there is good potential to manage complexes made up of ponds, lakes, wetlands, and surrogate grasslands.
