aquatic invasive species Meditations

A partnership between Vilas County and UW-Oshkosh for a pilot program to decontaminate watercraft using four lakes, two of which are infested with invasive spiny water fleas, was approved by the county board Tuesday.(2/27)

One of Wisconsin's worst aquatic invasive species, the spiny water flea, loves undrained live wells in boats.

This weekend, workers and volunteers will be out on area lakes hoping anglers and boaters help in stopping the spread of aquatic invasive species.

The first of three training sessions is set for Thursday designed to protect Northwoods waters from aquatic invasive species.

The state's waters are open again for another boating year, but the DNR's top aquatic invasive species person says staying vigilant will slow the spread of unwanted plants and critters.

The DNR's Bob Wakeman says boaters are required to inspect their boats and equipment before they launch to see what plants might be attached to the boat. He says be sure to drain water from vehicles, boats and equipment...

As you prepare your taxes, a DNR official hopes you consider a donation to the Endangered Resources Fund to help preserve rare plants and animals and high quality natural areas. The fund works with landowners, businesses, communities and other customers and partners to consider the potential impacts of land development, planning and management projects on rare and sensitive species and habitats very early in the project planning process.

The Director of the DNR Natural Heritage Conservation Bureau, Drew Feldkirchner says tax deductions are a key way they stay funded...

Educators remind boaters each summer about not transferring aquatic invasive species from one water body to another.

An Oneida County AIS coordinator says the same bit of wisdom also applies on frozen water. Stephanie Boismenue says invasives can spread as quickly in the winter as they do in the summer.

She says there are some things to remember...

A study by the DNR shows the spread of aquatic invasive species remains stable, which a leader says means prevention efforts are working.

DNR Aquatic Invasives Coordinator Bob Wakeman said they sampled 200 lakes over five years, the largest effort of its type in the nation...

"....we're happy to say the rate is not increasing. I wish I could say the rate was decreasing, meaning were beginning to stop the spread. The good news is it's not going up any faster...."

He says the longest term invaders continue to be the most difficult to deal with...

Volunteers are needed to help discover invasive species in the Northwoods. Volunteers will help the Oneida County AIS team search for invasive species in rivers and streams during the 3rd Annual Bridge Snapshot Day.

Oneida County AIS Coordinator Steph Boismenue talks about what happens..

"....AIS coordinators and volunteers go out in the field and we look at intersections where there is a road or bridge that crosses a river, thoroughfare or stream. We're looking for invasive species both terrestrial and aquatic...."

The July 4th holiday is traditionally one of the busiest boating times of the year. Lots of folks are going to be out trying to stop invasive species from going from one body of water to another.

This will be the DNR's 8th  annual invasive species landing blitz.

DNR aquatic invasive species communications specialist Tim Campbell says the effort focuses on reaching the largest number of boaters....

Workers will be out this weekend at Northwoods boat landings to try to stop the spread of aquatic invasive species. Oneida County Conservationist Michele Sadauskas says the first major weekend of the summer season is a good time to check boats and get out the word about stopping aquatic hitchhikers...

A report this week indicated it could cost up to $163 million  to control an invasive species in one well-known Wisconsin body of water: Lake Mendota in Madison.

A Northwoods specialist says a few northern lakes have been infested with the spiny water-flea as well. The critter is a small crustacean that feeds on the native zooplankton, especially daphnia, which keep the water clarity high. When the daphnia diminish, the water clarity tends to get poorer.

A near perfect growing season has made gardeners happy, but it also means a large growth of aquatic invasive species in our lakes.

Oneida County AIS coordinator Michele Sadauskas  says they've noticed abundant weed growth this summer  and more vegetation being hauled up onto landings...

" the same time we're getting some feedback from the wardens that people aren't paying a lot of attention what is coming off their boats and they're leaving some of that vegetation on the boats..."

The first Oneida County Clean Boats-Clean Waters workshop is Wednesday afternoon to help volunteers working boat landings this year some preparation.

Volunteers go to boat landings to work with boaters about not spreading aquatic invasive species from lake to lake.

Oneida County AIS coordinator Michele Sadauskas says with the fishing opener this weekend, it's a good time to update volunteers...

A provision of the state budget bill would eliminate a program that a local invasive species coordinator says helped them fight water invasives here in the north.

The Wisconsin Environmental Education Board helped get grants to Oneida county's A.I.S. program says Coordinator Michele Sadauskas. She says one grant enabled the program to hire a person to contact ice anglers...

"....they were able to talk to just over a thousand people...and we were able to gather a lot of data that we normally would not have during the winter time. So (WEEB) really helped us..."

Lake Gordon Clear of Yellow Floating Heart

It’s been over a year since monitors found Wisconsin’s first inland lake invasion of a plant called yellow floating heart in Forest County. The latest inspection did not reveal any new plants. 

It’s chilly grey day in late October, and it’s the last time this year that Forest County Aquatic Invasive Species Coordinator John Preuss will check for yellow floating heart. 

“What I look for is the shape of the leaf.  And when it’s flowering…and the seed pods are kind of tear dropped shape.”
