Dear Pierce County,
The management of invasive species is a key component when developing restoration sites in an attempt as a means to re-establish the native plant species. From our work in my Environmental 350 course at PLU, we discovered that herbicides are heavily used to diminish the invasive plant population. They are efficient and cost effective. However, the application of herbicides have unintentional environmental risks: they are toxic to applicators and they contribute to surface water pollution and bioaccumulation through exposure or consumption. For these reasons, I am requesting that for future restoration sites in the Chambers-Clover Creek watershed, the application of herbicides be avoided.
