Invasive Species Management
Treatment Plan Example
Since becoming state-certified in pesticide application, ESA has successfully managed invasive plants such as Japanese stilt grass (Microstegium vimineum), small carpetgrass (Arthraxon hispidus), mile-a-minute (Persicaria perfoliata), and common reed (Phragmites australis), while protecting and restoring desirable native species. This is a multi-step process which starts with a treatment plan.
The specialized treatment plan that ESA prepares for each site includes location, species, size and density of invasive plant patches, and methods of control. This plan may also include a planting plan if deemed necessary to prevent invasive re-establishment.

After proposing a treatment plan, ESA applies for a Toxic Materials Permit from MDE if the site requires herbicides. Typically, multiple herbicide treatments or phases are needed to control invasive plants until either the root stock has completely died or the seed source in the soil is depleted. Other situations allow for hand-pulling or management with cutting or mowing.
Before treatment begins, ESA documents existing conditions to provide the client with comparison photos upon completion. Any herbicide treatment is recorded in ESA’s log book and an evaluation of results are sent to the client when treatment is complete.
