Lewistown, M.T.  The Fergus Conservation District announced the detection of Eastern Heath Snails (Xerolenta obvia) in the Lewistown area. This is the first detection of the snail in Fergus County. This invasive species, native to Europe, poses a potential threat to local agriculture and natural habitats. The USDA – Animal & Plant Health Inspection Service confirmed the discovery after a report was sent to the Montana Invasive Species Council in late July. Subsequent sampling at the reported site revealed an established but isolated population. First detected near Belt, MT in 2012 this snail has since spread into Chouteau, Cascade, and Judith Basin Counties. Unlike native land snails, Eastern Heath Snails climb vegetation, propane tanks, fence posts, or vehicles and gather in large numbers called massing to escape ground heat, allowing them to be easily transported by people to new areas. A multi-stakeholder work group has been established. Plans to mitigate the Lewistown population of Eastern Heath Snails are currently under development and the Fergus Conservation District will hold a public meeting on Sept. 12 at the Eagles Lodge in Lewistown from 6 p.m. to 8 p.m. to raise awareness and discuss plans moving forward.  The public is encouraged to report suspected Eastern Heath Snail sightings to their local county extension office and to be diligent when transporting equipment and materials to ensure no snails hitch a ride.
