Control – To suppress, reduce or manage invasive species populations, prevent spread of invasive species from areas where they are present and take steps such as restoration of native species and habitats to reduce the effects of invasive species and to prevent further invasions.

Eradicate – To completely eliminate an invasive species from a specific part or all of the Tahoe Basin

Treatment area – The area on which actions have been performed specifically to control, manage or eradicate invasive species

Treatments performed should be reported by the end of December of each year, and treatments should be recorded only after they are complete, and regardless of their effectiveness. Treatment area should be rounded to the nearest tenth of an acre. If a certain area is treated twice, either for two different species or in two separate instances, both treatments should be reported.
