                       Fridays at 4 for Lakes

“Sedges, Rushes and Grasses of Maine Lakes”

This presentation will be technical in nature and cover the key features of sedges, rushes, and grasses. Lisa will describe the common and dominant species for each lacustrine habitat type. It is sure to be an exciting and informative final Fridays at 4 for Lakes for the 2022 season.

She is retired, and spent much of her professional career as an environmental scientist working in wetland ecology, permitting, and environmental impact statements for major infrastructure projects (including the Downeaster rail project and the Aroostook County Transportation study).

Our Mission

Lake Stewards of Maine (LSM) works to protect Maine lakes and to promote lake stewardship through widespread citizen participation in the gathering and dissemination of credible scientific information pertaining to lake health.


LSM is a non-profit 501(c)(3) organization committed to the collection of information pertaining to lake water quality. For 50 years, trained volunteers throughout Maine have donated their time so that we may all learn more about one of Maine’s most beautiful and important resources — our lakes.
