Wisconsin Wetlands Association launched our statewide Wetlands Threats Analysis in 2005 with the goal of identifying the top threats facing wetlands in Wisconsin to help guide the work of our organization and others doing wetland protection work in Wisconsin. Follow the links below to read more about this project and how you can get involved. Thank you to John Taylor for the financial support and vision to launch this project.

Analysis Approach
Our approach for the Wetland Threats Analysis is to assess threats to wetlands in Wisconsin by geographic region and by wetland community type. We have determined the geographic and wetland type classification systems that provides a structure for the analysis. Our classification system includes eight
geographic regions and twelve wetland community types (modified from the familiar system developed by Steve Eggers & Don Reed in Wetland Plants and Plant Communities of Minnesota and Wisconsin). We chose these regions and types to ensure that we address threats to all kinds of wetlands throughout Wisconsin, and because we wanted systems that were easily understandable by the general public. We have also reviewed many conservation planning documents and assembled a list of threats to wetlands that have already been identified.

We are consulting with statewide wetland experts to identify additional threats and then rank the threats according to the scope/extent, magnitude, and reversibility of each threat. We will also evaluate "opportunity areas" where tourism or recreation potential can contribute to wetland preservation efforts.

Geographic Regions
Wisconsin Wetlands Association has identified eight geographic regions for the state of Wisconsin based on physical and biological characteristics such as climate, geology, soils, water, or vegetation. These regions are based on the Wisconsin Department of Natural Resourcesí
Ecological Landscapes of Wisconsin, which we consolidated in consultation with DNR ecologists.

Wetland Community Types
For the purposes of our threats analysis, Wisconsin Wetlands Association has identified twelve wetland community types (modified from a classification system developed by Steve Eggers and Don Reed in Wetland Plants and Plant Communities of Minnesota and Wisconsin). This classification system is based largely on predominant vegetation and source and quantity of water. The twelve types of wetlands in our classification system are:

Alder Thicket Floodplain Forest Open Bog
Coniferous Bog Lowland Hardwood Swamp Seasonally Flooded Basin
Coniferous Swamp Low Prairie Sedge Meadow
Fen Marsh Shrub Carr

We also will examine threats to rare or localized wetland community types such as interdunal wetland and fresh wet meadow within regions where these types are present in Wisconsin. Not every type above is present in each geographic region. Within each geographic region, we will analyze threats only to those wetland community types that are present.
