aquatic invasive species

The Wisconsin Department of Natural Resources asks those out ice fishing to help prevent the spread

Outdoor activities can spread invasive species on land and in the water.

The Great Lakes’ frigid fresh water used to keep shipwrecks so well preserved that divers could see dishes in the cupboards

Aquatic Invasive Species are some of the greatest threats to lake health in the Northwoods.Once an invasive establishes itself in a water body, it can cost thousands of dollars to remove it, if removing it is even possible at all.Rusty crayfish has been one such invasive species.First introduced to Trout Lake in Vilas County in the late 70s and 80s, the crayfish quickly settled in with population estimates in the thousands by the late 2000s.But now it seems nature is correcting course.

Spiny water fleas are aquatic arthropods called zooplankton. Zooplankton are small shrimp-like creatures, and most of them survive by eating phytoplankton, the microscopic photosynthetic algae at the bottom of the food chain in lakes.

This cold snap has been good for making ice on lakes across the Northwoods.As fishermen get ready to drill some holes, conservationists are reminding them to be mindful of spreading invasive species.

As hunters move through woods and water, local conservationists warn them to beware of spreading invasive species.

Residents on the Buckatabon lakes have been fighting Eurasian watermilfoil for years. But the invasive species keeps spreading and the cost to control it keeps rising. Now, the lake association wants to involve more people in combatting the plant by establishing a lake protection and rehabilitation district.

In this week’s All Things Outdoors, the Department of Natural Resources is reminding anglers about some basic rules and how they can help keep lakes free of invasive species.
