Invasive Species & Herbicides

Limited herbicide treatment of aquatic invasive weeds
We advocate for limited use of herbicides to control aquatic invasive and nuisance weeds and are working to establish a comprehensive, ecologically sound, non-toxic approach to long-term management of vegetation in our waterways.
We worked closely with the City of Sandpoint in 2012 to establish and implement a new management program for aquatic invasive weeds at City Beach and the Windbag Marina using diver assisted hand-pulling. This program focuses on eliminating the need for chemical applications in our high-use swimming and recreational areas.
In addition, we support the use of biological control, which is the use of naturally occurring predators or pathogens to manage populations of aquatic invasive and nuisance weeds.
Through legislative action in the winter of 2015, our team’s efforts successfully changed Idaho’s Noxious Weed Law to allow for the movement of aquatic invasive weeds for the purposes of biological control research and implementation. With such a change, we hope to stimulate research into biological control agents and collaborate on their implementation as an additional tool to help safely manage the aquatic invasive weed populations in our watershed.
Invasion and spread of new aquatic invasive species
Certain invasive species can seriously threaten the stability of the aquatic ecosystem in addition to degrading water quality. Our team works to prevent the introduction and spread of new aquatic invasive species, such as zebra and/or quagga mussels, within the Lake Pend Oreille system by raising community awareness and distributing educational materials to the public.
