  • At Lulu Lake, Nature Conservancy and University of Wisconsin-La Crosse scientists are testing a new technique to help native plants compete with invasive Eurasian water milfoil. © Clint Farlinger
  • Eurasian water milfoil is a non-native aquatic plant that grows quickly in the spring in lakes and rivers. © Jerry Ziegler/TNC
  • It forms a thick mass of tangled stems underwater that get caught in boat propellers, rudders and trailers. Larger fish can’t swim into the dense mats to lay eggs. © Allison Fox, University of Florida, Bugwood.org
  • Dr. Tim Gerber, UW-La Crosse, and undergraduate student Margaux Huismann SCUBA dive to remove Eurasian water milfoil from Lulu Lake. © Jerry Ziegler/TNC
  • The milfoil is collected in floating “noodle” bags and removed from the lake to keep it from re-rooting; amount shown here was collected in 15 minutes. © Jerry Ziegler/TNC
  • The Conservancy and Dr. Gerber are testing the use of biodegradable coconut fiber mats to get native aquatic plants to grow in the places where milfoil was removed and give the invader some competition.

  • High school interns weave native pondweed into the coconut mats, which will be grown in a greenhouse and then placed in Lulu Lake in the summer. © Jerry Ziegler/TNC
  • If successful, this technique could be used in other lakes and rivers to reduce Eurasian water milfoil and keep waterways like Lulu Lake healthy for people and nature. © Jerry Ziegler/TNC
