The Oneida County Land & Water Conservation Department (OCLWCD) and the Lumberjack Resource Conservation & Development Council (RC&D) invite you to participate in the 6th Annual Northwoods’ Invasive Species Poster Contest. Area students in 4th through 8th grades are eligible to enter. The primary goal of this contest is to educate students about aquatic AND terrestrial invasive species that affect our Northwoods’ Counties.



  • IT’S A FACT: Lake Superior is home to 97 non-native aquatic species!*
  • IT’S A FACT: Since 2008, the Emerald ash borer, a terrestrial invasive insect, has been discovered in 42 of 72 Counties (58%) in Wisconsin. EAB kills all untreated ash trees within 3-5 years.
  • IT’S A FACT: Immature Zebra mussels cannot be seen by the naked eye and adult Zebra mussels can filter one quart of water each day robbing native species of vital nutrients.
  • IT’S A FACT: Japanese knotweed can grow horizontal root shoots, known as rhizomes, up to 60 feet long. This is why Japanese knotweed is one of the most difficult terrestrial invasive species to eradicate!
  • IT’S A FACT: White nose syndrome is an invasive fungus from Europe that can kill more than a million bats each year.
  • IT’S A FACT: Chinese, Japanese and Banded Mystery snails are intermediate hosts for parasitic worms and can transmit trematodes that kill waterfowl

Invasives are everywhere!

Our contest covers both aquatic and terrestrial invasives. Kids can create great posters highlighting critters like Emerald ash borer and Gypsy moth, and plants such as Japanese knotweed, Garlic mustard, Yellow iris and Glossy buckthorn. There is even an invasive called Rock snot! White nose syndrome, an invasive fungus, can kill a million bats in one year. Wild parsnip, a terrestrial invasive, can cause severe rashes and blisters if the sap touches your skin in the presence of sunlight.

We hope your students have fun creating posters using terrestrial and aquatic invasives while helping to educate others on the importance of stopping invasive species! Photos below show a small sample of subjects from which your students can choose. There are many, many more.

The 2017 contest is open to students in public, private, and home schools within the ’Northwoods’ and ’Northland’ regions of Wisconsin. Invasive species do not recognize county lines and neither should this contest!

There are four poster divisions : (1) Grade 4, (2) Grade 5, (3) Grade 6, and (4) Grades 7 & 8.
