Invasive Species

Invasive species include plants and animals (with a focus on insects) that are non-native to Connecticut and other areas of New England. In many cases, invasive species are non-native to the US. Invasive plants have been introduced into our area either accidentally or intentionally. They have escaped from the managed landscapes where they were originally planted to become established in natural areas, which are sometimes referred to as minimally-managed habitats. Over time, these invaders increase in population and become so widespread that they outcompete and displace native plants, resulting in losses of animal species that depended on native plants for food, protection, and shelter. The establishment and spread of invasive plants will ultimately reduce the value of these natural areas of woodlands, wetlands, and meadows.

The UConn IPM Program for Invasive Species provides information on the identification of non-native, invasive plants and insects and offers management solutions for many of these invaders. Invasive species information is found here and via links to other resources.
