Central Sands Pine-Oak Forest

State Rank: S3     Global Rank: G3   what are these ranks?

Definition

General natural community overview

Counties shaded blue have documented occurrences for Central Sands Pine-Oak Forest in the Wisconsin Natural Heritage Inventory database.

This forest community is associated with, but not limited to, the Central Sands ecoregion. Moisture conditions vary from dry to borderline dry-mesic. Soils are coarse-textured, acid sands, on landforms that can include glacial outwash, lakeplain, old dunes, and eroded sandstone-cored ridges. The canopy co-dominants vary, but in older, relatively undisturbed stands they may include white and red pines (Pinus strobus and P. resinosa), various oaks (Quercus alba, Q. rubra, and Q. velutina), and sometimes red maple (Acer rubrum), black cherry (Prunus serotina) and bigtooth aspen (Populus grandidentata). The depauperate understory of the drier sites is composed of a small number of vascular plants that usually include huckleberry (Gaylussacia baccata), early blueberry (Vaccinium angustifolium), bracken fern (Pteridium aquilinum), wood anemone (Anemone quinquefolia), and Pennsylvania sedge (Carex pensylvanica). Jack pine (Pinus banksiana) is sometimes co-dominant on the driest sites.

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 Central Sands Pine-Oak Forest, based on the Ecological Landscapes of Wisconsin Handbook.


Map of the Ecological Landscapes of Wisconsin.

Ecological LandscapeOpportunity
Central Sand HillsMajor
Central Sand PlainsMajor
Northeast SandsPresent
Northwest LowlandsPresent

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 Central Sands Pine-Oak Forest in Ecological Landscapes with opportunities for protection, restoration, and/or management. For more information, see the Wildlife Action Plan.

Central Sand Hills

Occurrences of this type are found at Emmons Creek State Fishery Area (Portage County), Hartman Creek State Park (Portage and Waupaca Counties), and Standing Rocks County Park (Portage County). Additional field inventory is desirable in parts of this Ecological Landscape.

Central Sand Plains

This Ecological Landscape is the best place to maintain large forest blocks for this type, and to implement the other conservation actions (e.g., encourage species and structural diversity, achieve balanced age-class distributions) because of the abundance of the type and the large public ownership. Fragmentation is a particular problem in some parts of this Ecological Landscape, due to residential development and road construction. Areas near the Wisconsin River were the first of the historic “pineries” to be logged during the Cutover. White pine forests are now regenerating in the Central Sand Plains, but are still considerably younger and smaller than the original pineries. A proportion of these white pine forests could be allowed to age and develop structural characteristics approximating those of the historic forest, to allow study of their habitat value. Important sites include the Overmeyer Hills complex, an extensive area of dry forest on sandstone ridges within the Black River State Forest (Jackson County), Quincy Bluff and Wetlands State Natural Area (Adams County), Mirror Lake State Park (Sauk County), and Dells of the Wisconsin River State Natural Area (Columbia County). Efforts should be made to maintain or enhance connectivity among large forested areas, including state, county and industrial forests.

Some of these photos explicitly illustrate unusual and distinctive community variants. The community photo galleries are a work in progress that we will expand and improve in the future.
