A guided walk to discuss invasive plants in northwestern Connecticut will be held July 14 from 9 to 10:30 a.m. at the Steep Rock Preserve riding ring in Washington.

The program is geared toward individuals 12 and older, with children accompanied by an adult.

Donna Ellis, co-chairperson of the Connecticut Invasive Plant Working Group (CIPWG), will lead the hike.

Invasive plants are a problem because they establish easily, grow aggressively, disperse over wide areas, displace native species, and reduce biological diversity.

These plants invade not only terrestrial habitats but water bodies as well, where they can grow and proliferate undetected for many years.

Ellis is a senior extension educator in the Department of Plant Science and Landscape Architecture at the University of Connecticut, where she has worked for 26 years.

She has a B.S. degree in Plant Science from the University of Rhode Island and an M.S. degree in Plant Science from the University of Connecticut. For more information and RSVP, visit www.steeprockassoc.org or call 860-868-9152.
