  • Two More Invasives to Look for in Michigan

    • Michigan’s invasive species watch list was recently updated to include two new species and remove another. Mountain pine beetle, a deadly threat to pine trees, and water-primrose, a fast-spreading aquatic plant, have been added to the watch list due to threats they pose to native ecosystems and industry. European frog-bit, originally listed in 2011, has been moved off the list of species of immediate concern and is now considered established in the state.
