The state of Michigan is suffering from an outbreak of Lyme - but it's not what you think. The Muskegon Chronicle reports that local naturalists have observed Lyme grass (Leymus arenarius, also known under the genus Elymus) naturalized in sand dune habitats along Lake Michigan. The grass is spreading but not yet out of control, which could make now a good time to try to eradicate the species from the dunes...assuming that there are no active pathways that could reintroduce it. The fact that Lyme grass continues to be a popular ornamental species could pose a problem for those hoping to exterminate it from natural areas.
