Researchers warn of economic damage from invasive mussels

KALISPELL, Mont. (AP) — Researchers are warning that invasive mussels could cost Montana's economy more than $230 million per year in three key economic sectors: recreation, infrastructure and irrigation.
The Montana Invasive Species Council commissioned the study by the University of Montana Flathead Biological Station.

The Flathead Beacon reports that the study released this week only examined a percentage of the total economic impact that invasive mussels could have on the state.
Council chair Bryce Christiaens says mussels can cover boat launches and beaches and cause damage to the state's ecosystems and infrastructure.
