2003 New London Invasive Species Town Survey

The New London Conservation Commission, recognizing the proliferation of invasive species in recent years, launched a town-wide survey in 2003 designed to determine the magnitude of the invasives problem in the area.

The survey was modeled after the White Mountain National Forest and Invasive Plant Atlas of New England (IPANE) surveys. Over 20 volunteers surveyed New London's public roads and multiple trails throughout the town using survey forms and informational packets to help identify species. Thank you again volunteers for all your help!

Fourteen of the thirty two species listed on the NH Prohibited Invasive Species List were found, including three species that are to be included as of January 1, 2007.

This Map of Invasive Species in New London shows that there are no concentrated locations, but rather many types of invasive species are scattered thoughout the town.

Several invasive species are plants that are often used in gardens including Burning Bush, Norway Maple, Japanese Barberry, Morrow's Honeysuckle, Tartarian Honeysuckle, Oriental Bittersweet, and Multiflora Rose.
