Mosquito Madness, Even in Autumn?

Despite several nights of frost in the past week, some Northern Wisconsin residents are still plagued by the telltale buzz of mosquitoes.  How does a mosquito survive in cold temperatures?

Common knowledge holds that once nighttime temperatures dip into the 30s, mosquito populations drop off.  But that didn’t seem to be happening last week.  Susan Paskewitz, a mosquito expert at the University of Wisconsin Madison, says it’s possible most of the still-active mosquitoes are newly formed.

The first stocking resulting from the state initiative to raise larger walleyes for Northwoods lakes began Thursday morning in Woodruff and Minocqua.

DNR crews were cornering then netting out the 8 inch fish from a rearing pond at the Art Oehmcke Hatchery in Woodruff.

It's part of an $10 million dollar state-funded effort to expand production at DNR state fish hatcheries. Production should increase five times to over 500,000 fingerlings by 2016. Sports groups have expressed concerns about the walleye population.

State Senator Tom Tiffany is supporting Oneida County’s call for increased cutting in the Chequamegon Nicolet National Forest.  

The county board passed a resolution Tuesday asking federal officials and members of Congress to bring the national forest harvest up to its allowable level.  Senator Tiffany says after widespread clear-cutting a hundred years ago, the pendulum has now swung too far the other way.

Some local officials aren’t thrilled with a state senate bill allowing Gogebic Taconite to cut off public access from its proposed mine site.  

The area sits on managed forest land, meaning property owners get a tax break if they open their land to public recreation.  Under a bill authored by Senator Tom Tiffany, GTac could close about 4000 acres and pay only a small increase in taxes, rather than a higher tax rate associated with managed forest closed to public access.

Typically, the dogs are trained to hunt bear in July and August. During that time, the dogs are in the woods and come into contact with wolves who have young, especially near what are called rendezvous sites.


DNR Large Carnivore Specialist David MacFarland says the depredation numbers are up...

Sparse Season For Lac du Flambeau Wild Rice

Wild rice production looks below average in the Lac du Flambeau reservation area.  

Scott Smith and the other two wild rice chiefs for the Lac du Flambeau reservation check lakes daily to monitor the rice as it ripens.  Smith says the peak of the harvest has probably already passed. 

“Usually 5 to 10 percent ripens per day.  So there are a few lakes left that still have rice – where it’s more dense, they still have rice to harvest.”
