Never Too Early to Plan for Native Flowers, Grasses, Trees

It’s still the middle of winter - but for some gardeners it’s not too early to look ahead to spring.  

The Iron County Land and Water Conservation Department runs a program to promote native plants for gardens and yards.  The program includes a mid-winter sale, where gardeners can pre-order native varieties for pick-up in May or June.  WXPR’s Natalie Jablonski spoke to the department’s Heather Palmquist about the native plants program.  

Palmquist says native plants are well-suited for Northwoods growing conditions.

State foresters are set to begin a three-year timber management project in the Laona School Forest.  DNR officials and Laona students gathered Wednesday to kick off the project. 

DNR Forestry Supervisor Craig Williams says the project will benefit forest health. He says some of the trees in the oldest school forest in the country are aging, and are being affected by invasive buckthorn.

Another invasive plant is threatening the shorelines of our northern waters...a plant that has taken over large stretches of Lake Michigan and Green Bay shores. 

It's called phragmites. Ken Krall spoke with Vilas County invasive species coordinator Ted Ritter about the threat from the tall plant that's very aggressive...

Deer Hunters: Leave Firewood At Home

State officials urge hunters to buy local firewood to prevent the spread of invasive pests.

The “buy where you burn” principle still applies in hunting season.  

The Wisconsin Department of Trade and Consumer Protection is reminding hunters not to haul firewood long distances when they head to their deer camps. 

Department spokesperson Donna Gilson says doing so could introduce new pests to an area. 

“There’s always that temptation to bring firewood with you because you’ve got some right in your backyard. IT’s never a good idea to haul firewood around the state.  And in some cases it may actually be illegal to do so.”

Study Reveals Nuances of Aquatic Invasive Behavior

We usually think of an invasive species as taking over its environment, at the expense its native counterparts.  

But a new study from the University of Wisconsin Madison’s Center for Limnology challenges that assumption.  It compiled survey data from a variety of studies on aquatic species, and finds that most of the time aquatic invasives keep a pretty low profile.  WXPR’s Natalie Jablonski sat down with Gretchen Hansen, lead author on the study.

Fourth graders from Central Intermediate School in Rhinelander had a chance to learn about invasive species Thursday, on an environmental education field trip. 

Michele Sadauskas is passing around Louis – a preserved sea lamprey to a group of kids sitting on the floor at CAVOC, the Cedric A. Vig Outdoor Classroom.   Sadauskas is the Aquatic Invasive Species Coordinator for Oneida County.  She’s here today to give kids a primer – what exactly is an AIS?

How to Mix a Lake

If you frequent lakes in the Northwoods, you know that invasive species are a big problem.  Take rainbow smelt – the tiny fish are known for outcompeting native fish and devouring their young.  Once rainbow smelt get into a lake, it can be all but impossible to get rid of.  Some approaches rely on chemicals that wipe out all fish species.  But one project out of UW’s Trout Lake Research Station is experimenting with a new technique that could have many fewer side effects than the chemical method.

Invasive species have continued to be a problem here in the Northwoods.  Nonnatives like the Eurasian water milfoil can threaten the ecology of lakes and disrupt summer recreation. 

Next week the Minocqua Brewing Company will host a public discussion of aquatic invasives.  It’s part of a monthly series at the brewpub called Science on Tap.  We sat down with the two scientists, Ben Beardmore and Alex Latzka, who will be talking about their research next week.
