Information on Powerline Right-of-Way Vegetation Management

May and early summer is the best time of year to recognize ericaceous  and other shrub species – like blueberries, laurels, and arrowood – when they are in bloom. A preponderance  of flowering native shrubs warrants a concerted effort to secure an alternate management regime for  those areas – not frequent close mowing. We recommend marking the limits of the shrub patches, to make them easier to avoid. If photos of a blooming shrub, including a close-up of a flower and a few leaves, are posted on the CT Botanical Society Facebook page, we may well be able to help with identification.

4/12/19 – CLCC and Eversource Energy hosted a forum with Dr. Robert Askins who presented specific guidelines for managing habitat for early successional birds (as well as New England Cottontails) on powerline corridors and in other open areas on land trust preserves. Following Dr. Askins’ presentation, representatives from the Eversource Vegetation Management team presented on current management objectives, protocol and maintenance schedules as it relates to transmission corridors.

Reports on Vegetation Management on Powerline Corridors

If an Eversource powerline runs through one of your preserves, this right-of-way (ROW) probably provides important habitat for rare and declining species of plants and animals that require open habitats. When Eversource alerts you that they will be conducting work on the ROW on your property, you have the opportunity to meet with an Eversource representative to discuss how this can be accomplished while minimizing impacts to important habitats.

View two reports, authored by Robert Askins, Professor Emeritus of Biology, Connecticut College and the Connecticut Botanical Society, which describe proven methods for maintaining transmission lines while preserving a biologically rich plant community dominated by native shrubs, grasses and wildflowers.

In early April 2019, Eversource hosted a forum on their vegetation management practices for several environmental stakeholder groups concerned with varying taxa (birds, plants, amphibians, reptiles, etc.) at their campus in Berlin, CT. CLCC hosted a second forum on August 12, 2019.
