A UW Madison researcher says close to forty percent of the state’s lakes could contain invasive species.
According to the Wisconsin DNR, that figure is currently documented at less than ten percent.
But Jake Vander Zanden of the UW Madison’s Center for Limnology says his team surveyed a random sample of Wisconsin lakes to estimate how many might be affected by invasive species statewide, and came up with a much higher number.
Deer Advisory Councils have been meeting across Wisconsin as part of a reform effort within the DNR to manage the state's deer herd. The councils will release preliminary recommendations beginning next Monday.
DNR big game ecologist Kevin Wallenfang says each county councils will make recommendations on local deer populations. Wallenfang says beginning Monday, more input on the recommendations will be sought....
It’s duck hunting season in the northwoods and while plenty of artificial decoys will be used by waterfowlers to lure birds within gun range one thing they won’t be using is live decoys.
This technique of waterfowl hunting was regulated out of existence in 1935, partly because of the severe drought of the early 1930s that devastated waterfowl populations. But the practice was once common and even celebrated.
Researchers at the Wisconsin DNR are looking for answers as to why walleye populations are declining in the state.
DNR Research Scientist Gretchen Hansen says adult walleye numbers are declining statewide by an average of two percent per year.
“So there’s a lot of variability. So in some lakes, populations are going up, but in the majority of lakes populations are going down. And a lot of that is driven by failed recruitment, so failed reproduction.”
The Wisconsin DNR is waiting for the next move from Gogebic Taconite, now that the company has stopped fieldwork operations for the year.
DNR hydrologist and project lead Larry Lynch says activity on the proposed mine site wrapped up last month.
“They stopped their data collection in regard to surface monitoring, so right now there’s really nothing going on on the site. They also stopped their road improvement work on one of the access roads.”
