Matthew Mitro and John Lyons of the Wisconsin DNR and Jana Stewart of the U. S. Geological Survey recently modeled the effects of changing climate on Wisconsin trout. They concluded that stream temperature is the most important factor determining where trout can live and cannot live. A warming climate will affect the distribution of trout in the state. Extreme precipitation events associated with climate change may limit trout recruitment and drought conditions associated with climate change will limit stream flows and fish habitat.
