Invasive Species
Over the years, a variety of non-native species (plants, animals, and other organisms) have been introduced to Connecticut. Non-native species are those that are alien to the ecosystem that they have been introduced into and whose introduction causes or is likely to cause harm to the environment or human health. Some non-native species exhibit an aggressive growth habit and can out-compete and displace native species. These are referred to as invasive species and they are a serious problem in Connecticut and elsewhere.
Protecting native species and the habitats in which they occur is an objective of the Department. To address the issue, the Department has taken measures to control and remove invasive species on state land while offering assistance to private landowners seeking to manage invasive species on their properties.
