A program, “The Importance of Trees,” will be presented April 30 at 2 p.m. at Washington Montessori School.

The program is sponsored by the Lake Waramaug Association as part of its centennial celebration, during which the group is launching programs to “Plant 100 Trees and Save 100 Acres Around Lake Waramaug.”

The Warren Land Trust and the Steep Rock Association are co-sponsors of the event that will feature guest speaker Jeffrey S. Ward, chief scientist in the Department of Forestry & Horticulture at The Connecticut Agricultural Experiment Station.

Trees are important to the environment and provide a broad range of personal, community and global benefits.

They beautify the environment, soften the edges and relieve the hard surfaces of the increasingly urbanized and suburbanized world, clean the air we breathe, provide food and habitat for wildlife, and play a vital role in protecting wetlands, watersheds, aquifers and groundwater supplies.

Trees increase water quality in several key ways and play an important role in reducing the effects of climate change.

Ward received a B.S. in forest biology, a M.S. in silviculture at Ohio State University and a Ph.D. in forest ecology at Purdue University.

He has been in the Department of Forestry & Horticulture at The Connecticut Agricultural Experiment Station since 1987 and has been chief scientist since 2004.

He is the author of more than 90 papers and is a frequent speaker on a range of topics, including forest management, tree care, urban forestry and forest ecology and health.

The school is located at 240 Litchfield Turnpike (Route 202).
