Invasive Mussels Could Cost Montana $234 Million Per Year (Jan 24, 2019) (PDF | 191 KB)
Montana Invasive Species Council.
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).
