Did you know that even when the temperature plummets and a layer of ice covers the water, there are still plants growing under the surface?
Unfortunately, many of these non-native plants, alga and mussels that survive the winter and come back in spring in full force.
Aquatic plants to be particularly on the lookout for are Eurasian watermilfoil and curly-leaf pondweed. Both plants are tolerant of darkness and cold, making it easy for them to survive over a frigid winter. Curly-leaf pondweed sprouts your plants(turions) in late fall/winter that remain green and will grow under the ice if enough light comes throuh, allowing it to get a head start over many native plants. Also, be on the lookout for Zebra

Mussels and starry stonewort. Starry stonewort, invasive alga, have plant parts that will die over the winter, but reproductive centers(white, star-shaped bulbils)survive in the sediments of the lake.
If you are venturing out on the ice this winter, you can help prevent the spread of invasive species. If plant materials get caught up in your fishing lines, dispose of them in the trash or leave them behind on the top of the ice before moving to a new fishing spot or lake.
Any leftover bait should also be disposed of in the trash-never release minnow or other bait into a lake as a means of disposing them!

In 2018, we will observe National Invasive Species Awarenss Week from February 26 through March 2. The point of this annual event is to raise awareness and identify solutions to invasive species issures. The event explores how non-native, invasive plants, animals and pathogens impact people, as well as what we can do to prevent the spread and effectively manage them.
Ways you can help:
-Clean hiking boots, waders, boats and trailers, off-road vehicles and other gear to stop the invasives from hitching a ride.
-Avoid dumping aquariums or live bait into waterways.
-Don't move firewood! Buy it where you will burn it.
-Plant only non-invasive plants in your garden and remove any known invaders.
-Report any known or suspected invasive species to authorities.
-Volunteer to help remove invasive species from natural areas.
-Ask your political representatives at all levels to support invasive species control effects.
