It’s no accident that both Arbor Day and Earth Day are celebrated in April, and in Greenwich there’s another April nature-related celebration, that of the annual Greenwich Tree Conservancy’s Tree Party to be held on Arbor Day,Friday, April 28th at McArdle’s Greenhouse from 6:30-8:30 PM. The theme of this year’s Party is the celebration of the 10th anniversary of the Greenwich Tree Conservancy, started in 2007 by a small group of environmentally concerned Greenwich residents who wanted to preserve the town’s urban forest which they saw slipping away.. The Conservancy’s mission in the last ten years has fulfilled that goal with over 2500 trees planted on public and non-profit lands, in partnership with the Town’s Tree Department. In addition to planting trees, the Conservancy’s mission includes an educational component with lectures, workshops, and tree walks all dedicated to learning about trees, their planting and maintenance. Cocktails, hors d' oeuvres will be served and there will be door prizes for raffle tickets
