Ken’s story, “Finding the Invisible,” follows the struggle to stop the spread of invasive species around Flathead Lake, Montana. Through the use of a up-and-coming tool called environmental DNA, scientists at the University of Montana can find a single cell of an organism carried in a drop of water. While many invasive species are already present in the West, aquatic plants are the greatest threat to local economies and ecosystems if introduced and allowed to spread. The recent arrival of invasive mussels, found for the first time in several bodies of water in the Missouri River drainage in fall 2016, once again signaled the need for streamlined detection.
