INVASIVE VEGETATION MANAGEMENT

Invasive species are damaging to an ecosystem in many ways. Their persistent nature allows them to outcompete native vegetation for resources. Often, invasive vegetation has a shallower root system than native plants, making land more susceptible to erosion. Management methods for invasives are numerous, so all options should be considered before implementing a management strategy. The following overview can serve as a general guide to this process.

Overview:

Identify invasive species present, common shoreline invasive species include: japanese knotweed, common reed, and purple loosestrife,

For more help identifying invasive species check out this resource⁵⁰.

Record the location of these species and determine their spread. It can be helpful to draw out a map. Revisit these sites in the future to ensure effective management efforts.
Consult this invasive management plan guide⁵¹ to determine an appropriate management guide.
Implement your strategy.

Chemical removal may be prohibited on your property due to Vermont state regulation⁵² on herbicides near water bodies. For more information and additional resources in chemical removal checkout page 3 of the Vermont DEC’s invasive species management guide⁵³.

Regenerate impacted areas

Revegetating with native species by collecting seeds from local natives or purchasing appropriate vegetation.

Consider brush layering or live staking

Continue physical treatments

Monitor progress

Removal Practices

Physical Removal:

There are three types of physical removal, including hand pulling, cutting, and smothering. For more information on physical removal visit this guide⁵⁵ from the University of New Hampshire or pages 19-21 of this Vermont specific guide⁵⁴. For specific information on Japanese Knotweed, Common Reed, or Purple loosestrife click here.

Chemical Removal:

Chemical removal is highly discouraged for any plant removal because of the potential human health risks as well as risks of damage to the local ecosystem. Due to Vermont state regulations⁵² on the application of herbicides near water bodies, it is very likely that herbicide application is prohibited on your waterfront properties.
