Non-Native Invasive Species - Overview

Native plant populations throughout Vermont are being supplanted by non-native invasive plants. To the extent these invasions are successful, habitat "services" provided by native plant communities - food, protection from prey and weather, places for breeding and nesting, regulation of water temperature, and others - are diminished. Along streams and rivers, water quality too is impaired, as organic inputs are altered, runoff regimes are changed, and banks are destabilized by plant species whose roots are rhizomatous and ill-equipped to protect banks from erosion.

In 2012, the State of Vermont updated its Noxious Weed Quarantine rule to regulate the importation and movement of a number of invasive plants. Many of them are familiar to gardeners and naturalists in the region, and include goutweed, garlic mustard, bush honeysuckles, buckthorns, and purple loosestrife. New to the list are burning bush, the barberries, and Norway maple. It is illegal to move or sell these species.

In 2015, BCCD was awarded a grant for $36,700 from the National Fish and Wildlife Foundation to create a Batten Kill Watershed Comprehensive Invasive Species Management Association (CISMA). The goals of the two-year initiative include implementing an early detection/rapid response program for Japanese knotweed and barberry species at several locations, public and private, around the watershed, and continuing  public outreach and education efforts, targeting as wide a range of landowner interests as possible. The steering committee will be hiring a part-time coordinator in early 2016.
