Ag Officials Investigate Invasive Snail (Aug 15, 2012)
Montana Department of Agriculture.
Montana Department of Agriculture and U.S. Department of Agriculture officials are investigating the discovery in Montana of a land-dwelling snail species not previously found in the western United States. USDA's Animal and Plant Health Inspection Service confirmed August 9 that terrestrial snails collected about 20 miles southeast of Great Falls were eastern heath snails (Xerolenta obvia), a species native to eastern Europe that spreads by attaching to cargo containers or other conveyances used in international shipping.

Common Native and Invasive Wetland Plants in Montana Booklet (May 2012)
Montana Department of Environmental Quality.
This booklet was developed, primarily for the non-botanist, to assist in identifying potential wetland areas based on the present. Because wetland management and regulation is complex, we wanted to provide a basic tool to assist local government staff and decision makers, among others, in identifying potential wetland areas. This booklet is not meant to be used to identify the jurisdictional boundaries of a wetland, but rather to identify potential wetlands that may need further evaluation by a trained wetland scientist.
