Schroeder, Jason Mills, Erica Young, James ReinartzDept of Biological Sciences and Field Station, University of Wisconsin-Milwaukee 1941 BACKGROUND Cedarburg Bog is a large, forested wetland in SE Wisconsin. Formally protected since 1952, this unique wetland remains relatively undisturbed. Land cover changes on this primarily agricultural landscape could influence the wetland by altering groundwater flow and the corridors that provide native and exotic species access to the wetland. As part of a long-term study of ecological changes in Cedarburg Bog, we analyzed historical and contemporary land cover from aerial photographs to quantify landscape changes between 1941 and 2000 within the 10,000 ha area surrounding the wetland. 2000 Cover classes Agriculture Forest Water Emergent wetland Shrub wetland Forested wetland Areas of reforestation between 1941 & 2000 = increase in forest cover Larger forest patches, closer to one another Larger number of smaller agricultural patches due to increasing forest cover Land cover maps focal area (~2,500 ha) RESULTS – Changes on landscape surrounding Cedarburg Bog Aerial views of Cedarburg Bog and surrounding landscape Saukville, Wisconsin Land cover classification (10,000 ha) Aerial photographs METHODS CONCLUSIONS Landscape changes : ,[object Object]](https://image.slidesharecdn.com/wwcposterfinalversionprint-12967880425545-phpapp02/85/wisconsin-wetlands-conference-poster-cedarburg-bog-land-use-historical-classification-1-320.jpg)
