Montana’s economy could see more than $230 million in annual mitigation costs and lost revenue if invasive mussels become established in the state, according to a report released by the Montana Invasive Species Council (MISC). Commissioned by MISC and completed by the University of Montana Flathead Biological Station, the economic impact study provides “a snapshot of projected direct costs to affected stakeholders dependent on water resources,” said Bryce Christiaens, MISC chair. “It does not reflect the total economic impact to the state, which would be considerably higher.” View a one-page fact sheet [PDF, 484 KB] or the full report [PDF, 4.0 MB].

To better understand the impacts of invasive species on infrastructure managed by the federal government an effort was undertaken by the National Invasive Species Council Secretariat to solicit feedback from those agencies. A questionnaire was sent out to the federal agencies that manage infrastructure to identify the impacts they have observed, how they are managing them, issues they have identified and resource needs. The research demonstrated that impacts from invasive species on federally managed infrastructure range from non-existent to significant. Identified gaps needing improvement include awareness and education of invasive species impacts, limited resources, insufficient policy, and lack of agency support.
