What is Harvesting? Operational Considerations for your lake. Expected Results from a Weed Harvesting Program.

The Environmental Protection Agency has determined that the endocrine-disrupting pesticide atrazine and cancer-linked pesticide glyphosate are each likely to harm more than 1,000 of the nation’s most endangered plants and animals.

Starry stonewort was first discovered in Minnesota waters in Lake Koronis in 2015. It’s now found in 19 Minnesota waterbodies. Lake Koronis is helping researchers understand how a changing climate may influence this invasive and how we can better manage it. Overall, the research showed year-to-year variability in the total biomass of starry stonewort. There
Lake managers might be hurting native aquatic plants – instead of helping them – when they use chemicals to control invasive plants on entire lakes. New research by Wisconsin DNR Lakes and River Team Leader Dr. Alison Mikulyuk shows native plant communities can struggle when chemicals are used to target invasive Eurasian watermilfoil. It appears

In the past 100 years, the planet has warmed in the range of 10 times faster than it did on average over the past 5,000. In response, thousands of species are traveling poleward, climbing to higher elevations, and diving deeper into the seas, seeking their preferred environmental conditions. This great migration is challenging traditional ideas
