Anyone interested in attending a session should always contact the park to make sure the program is on as scheduled, because the schedule occasionally changes.

We think this study will help us understand what we can expect to see if old growth forest eventually develops along stream banks, and if steps are taken to ensure that wood falling into the streams isn t removed.
Researchers believe that historically, more woody debris existed in northern streams.
I think the primary reason why habitat improvement structures work so well in our trout streams is because these streams are starved for cover because of the low volumes of natural wood. To improve habitat, fish managers have been using a variety of techniques including placing half logs, deflectors and boom covers to create cover for trout. While other U.S. studies have looked at the effect of woody debris in streams, most of those studies occurred in areas very different from northern Wisconsin, such as the Pacific Northwest with its steep mountains and larger conifers. The National Marine Fisheries Service is helping to fund the research in northern Wisconsin because of its interest in trout and salmon species that migrate from the streams to the Great Lakes. The DNR has provided matching state funds and Sport Fish Restoration funds are also being used.
