Invasive Species

Invasive species are non-native species that can cause harm to the environment or to human health. As a threat to our biodiversity, they have been judged second only to habitat loss. Cornell Cooperative Extension Dutchess County provides education through workshops and outreach to help people and communities identify and manage invasive species as well as learn about alternatives.

Dutchess County has numerous farms, four colleges, the Culinary Institute of America, many parks, museums, golf courses, trails to bike, hike or horse ride, historic villages and quaint hamlets.  It is a desirable place to live and visit.  Invasive plants, insects and aquatic species can have a negative impact on the ecosystem.  Native plants and animals can be diminished; landscapes that once were a pleasure to view could become a blanket of one or more invasive plants.  Thousands of dollars are spent each year in an attempt to control the spread of invasive species.

If you suspect you have found a new invasive plant or insect, please call the Horticulture Hotline at 845-677-5067. The hotline is open Wednesdays, from 9-noon, April through October.
