Tracking and Learning about the Mammals of the Cedarburg Bog and Ozaukee County

Sunday, January 21, 9:00 AM to Noon

Join Julia Robson on this indoor/outdoor exploration of anything you ever wanted to know about the fascinating and mysterious mammals which inhabit our area. The second half of the program entails looking for mammal scat and winter tracks in the Bog.  Wear winter boots and warm clothing.


Winter Hike and Chili Potluck

Sunday, January 28

Winter Hike 1:30 to 4:30 PM

Chili Dinner    4:30 PM

Winter presents the opportunity to explore the interior of the Cedarburg Bog. Field Station Director, Jim Reinartz will lead the annual hike into the heart of the Bog. This is a 4-mile hike, and weather or snow and ice conditions can make this hike challenging.  In the past we have hiked in bitter cold, on a warm day with wet slush over the ice, in deep snow, with no snow at all on very slick ice, and when we were lucky, with a little snow over solid ice.  The Field Station website (http://uwm.edu/field-station/) will be updated several days prior to the hike with snow and ice conditions.

You don’t have to hike to join us for the chili potluck.  We will provide the chili and beverages; if you can, bring a dish to share.  

Suggested donation for the Hike and Dinner is $5

Bog Guardian Program

With funding from the Ozaukee Washington Land Trust and the WI DNR-Citizen Based Monitoring Program, the Friends of the Cedarburg Bog have initiated a new program.

The Bog Guardian Program is designed to stop the advance of invasive plants, such as Teasel and Wild Parsnip, that have yet to reach the Bog, the UWM Field Station and nearby State Natural areas.

We have hired Jamie Sue Beaupré to manage this program. She has already begun working to develop a cadre of volunteers, Bog Guardians, to patrol area roads to locate, eradicate and monitor invasive plants. She has also contacted area road/highway departments to lay the groundwork for ongoing cooperation and support. We will also be contacting neighboring landowners to elicit their cooperation and support.

Once established, it is intended that the Bog Guardians, with help from neighboring landowners and communities, will sustain this program into the future and keep invasive plants out of the Bog, UWM Field Station and State Natural Areas.

For information, contact:

Jamie Sue Beaupré, Manager

Mud Lake Boardwalk Completed

Good News! The new Mud Lake boardwalk is complete! As you may know, the Wisconsin Natural Resources Board approved the Department of Natural Resources master plan for the Bog in May, which included plans to build a rustic boardwalk from Cedar Sauk Road to Mud Lake. The project included a 15-foot boat storage area for duck hunters during the waterfowl hunting season.

Last month the lumber was delivered to the shop at the UW Field Station. After a drying period, construction started and that construction is now complete. We hope this boardwalk will enhance the experience of all who enjoy the Mud Lake area, which includes duck hunters, bird watchers, kayakers, and wildlife lovers.

Thank you to all the volunteers that helped make the new Mud Lake boardwalk a reality!
