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. And in forests, regeneration is reduced when non-native species move in.

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 two-year initiative produced a partnership agreement between seven partners – the Batten Kill Watershed Alliance, the Bennington County Conservation District, the Bennington County Regional Commission, Calfee Woodland Management, the Equinox Preservation Trust, the Green Mountain National Forest, the Natural Resources Conservation Service, and the Vermont Land Trust. Those partners prepared a five year management plan and a communications plan, and hired a coordinator for the 2016 field season.

She organized the treatment of about 30 acres of barberry (with scattered specimens of other invasive forest species), 0.6 acres of loosestrife, and 4 acres of Japanese knotweed on seventeen different public and private parcels of land, and reached about 700 people with news of CISMA initiatives.

For each of the last three years, Vermont’s EcoAmericorps program has provided us with a service member, who takes on the day-to-day responsibilities of the organization for the year. We will welcome our newest member, Ryan Kincaid, in September 2019. After teaching for several years, Ryan hopes to return to her roots in the environmental sciences. You can follow her exploits on the CISMA’s Facebook page and on Instagram.

The list of invasive plant species continues to grow. 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.
