Thwarting Aquatic Invaders

Overview

Invasive species have few natural predators or control agents, allowing them to reproduce and grow rapidly and threaten ecological stability, and the diversity and abundance of native species. They can also threaten our traditional uses of lakes and rivers for agriculture, domestic water supplies and recreation. Exotic species can be transported to new sites attached to boats, trailers, and equipment. Many of these invasive species have the ability to withstand extended periods of time out of water or in small amounts of water, making their transport to new locations possible.

Flathead Lake and the other waters of the Flathead watershed are at risk due to the potential for accidental introduction of invasive aquatic species. Zebra mussels, Eurasian watermilfoil, whirling disease, and New Zealand mud snails are a few of the destructive and aggressive invader species that threaten our waters.

Species specific information

Montana’s action plan

In October 2002, Montana finalized a statewide management plan to deal with aquatic nuisance species, and in February 2004, Montana Fish, Wildlife and Parks hired a statewide coordinator to implement the plan. The main emphasis of the plan is to prevent the spread of these invaders into new locations. Once introduced into a new location, there is usually very little that can be done to mitigate the impacts.

Flathead Basin action plan

The Flathead Basin Aquatic Invasive Species Work Group formed in 2009 to expand efforts to prevent introductions of aquatic invaders in the watershed. Participants include resource management agencies from federal, state, tribal and local governments and conservation groups. The Flathead Basin Aquatic Invasive Species Action Plan was finalized in 2010 to guide our collaborative efforts and build prevention and education programs, as well as help secure funding for boat inspection and wash stations and other prevention strategies.
