Dry-mesic Prairie

State Rank: S2     Global Rank: G3   what are these ranks?

Definition

General natural community overview

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

Historically, this grassland community was common in parts of southern Wisconsin, occurring on slightly less droughty sites than Dry Prairie. Today, this community type is rare because of conversion to agricultural uses or the encroachment of woody vegetation due to the lack of wildfire. Dry-mesic Prairie has many of the same grasses as Dry Prairie, but is dominated by taller species such as big bluestem (Andropogon gerardii) and Indian-grass (Sorghastrum nutans). Needle grass (Stipa spartea) and prairie drop-seed (Sporobolus heterolepis) may also be present. The herb component is more diverse than in Dry Prairies, as it may include many species that occur in both Dry and Mesic Prairies. Composites and legumes are particularly well-represented in relatively undisturbed stands.

Soils are often somewhat sandy, either loamy sands or sandy loams. The landscape associations that can support this type include terraces on the margins of large river valleys, sandy outwash deposits, gravelly moraines, and the lower slopes of Driftless Area bluffs. As with the other tallgrass prairie communities (Mesic Prairie and Wet-mesic Prairie), well over 99% of this prairie type has been lost.

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 Dry-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 Dry-mesic Prairie in Ecological Landscapes with opportunities for protection, restoration, and/or management. For more information, see the Wildlife Action Plan.

Central Sand Plains

The type is very rare in the Ecological Landscape. Most of the few occurrences that have been documented are in rights-of-way, and have been seriously degraded by the encroachment of woody plants and colonization by invasive weeds. There may be limited opportunities for restoration and expansion in this Ecological Landscape, but the priority and feasibility of these have not been adequately assessed. An example is found at Mill Bluff State Park (Juneau County).

Southeast Glacial Plains

Historically common in this Ecological Landscape, the type is now very limited in extent, but there are more opportunities here than in most other Ecological Landscapes. The relatively flat topography of the Ecological Landscape led to extensive conversion of prairie to agriculture. Areas that are sandy, relatively infertile, steeply sloping, or where bedrock is near the surface, were less likely to have been plowed. Such sites are where most remnants are found. Most examples are along the southeastern edge of the Ecological Landscape near the relatively rugged Kettle Moraine, and in the southernmost portion of the Ecological Landscape that was not glaciated during the Wisconsin Ice Age. Elsewhere, most of the remnants are restricted to rights-of-way. Urban expansion is occurring in some locations, especially near larger cities, and can further impact prairie remnants and limit the opportunity to manage with prescribed fire. Many dry-mesic prairie remnants exist, however acreage is not extensive (e.g., Westport Drumlin Prairie (Dane County), Arlington Prairie and Hawk Hill (Columbia County), Muralt Bluff Prairie and Oliver Prairie (Green County)). Most of the high-quality remnants are being protected and managed appropriately. Opportunities to connect remnants and expand grasslands that can be managed compatibly with prairies should be sought. Grazing is not occurring on the quality remnants at this time.

Southwest Savanna

Historically common in this Ecological Landscape, the type is now limited in extent. Conversion to agriculture has occurred throughout the Ecological Landscape, but there are important opportunities for restoration in large acreages of pasture that have never been plowed. Methods of grazing that are compatible with grassland management objectives should be studied and developed. Large-scale prescribed burning, or other means of reducing woody vegetation or weeds, may be needed. Urban expansion is occurring in some locations and can impact prairie remnants and limit the opportunity to manage with prescribed fire. Underwood Prairie (Iowa County), Mud Branch Prairie (Lafayette County), and Green$apos;s Cemetery Prairie (Green County) are examples of this type.

Western Coulee and Ridges

Historically common in this Ecological Landscape, the type is now limited in extent. It is occasionally found on wider ridge tops, below dry prairies on lower hill slopes, and on terraces along larger rivers. The flatter topography where this community type occurred was more extensively converted to agriculture and residential development, but there are still important opportunities for restoration. Urban expansion is occurring in locations around larger cities. Examples of this type are found at Black Earth Prairie State Natural Area (Dane County), Avoca Prairie State Natural Area (Iowa County), Midway Railroad Prairie State Natural Area (La Crosse County), La Crosse River Trail Prairie State Natural Area (Monroe County), and Snake Bluff (Juneau County).

Western Prairie

The type is extremely rare in the Ecological Landscape because of the almost total conversion of prairie to agricultural uses. Urban expansion is occurring and increasing rapidly throughout the Ecological Landscape. A few sites on Waterfowl Production Areas are suited for restoration. Examples are found at Bass Lake Prairie, Ulrich Prairie, and Ogburns Prairie (St. Croix County).
