Non-native invasive plants are one of the biggest threats to biodiversity and a major challenge in conservation. They negatively affect property values, agricultural productivity, public utilities, fisheries, tourism, outdoor recreation, and ecosystem function, and are estimated to cost the U.S. $120 billion in economic damages and control each year. There are now more than 100 non-native species of plants that have become established in Connecticut! Can you identify them all? Come to Great Hollow on Sunday, June 30th to learn how to identify many of these plants, hear about how and when they were introduced to our region, and find out what you can do to be a responsible property owner. Free for members; a suggested donation of $5/person for non-members is greatly appreciated. Please sign up by emailing John Foley at .
