Invasive species are well known for their huge ecological costs, but they also bring a massive economic burden with sociological, environmental and health impacts. New research led by the University of Aberdeen and the University of Auckland in collaboration with CNRS, France has established that invasive species have cost the New Zealand economy almost $100 billion in the last 50 years. While damage costs remain high, this total includes spending far more than most other countries on pre and post-invasion management techniques relative to its GDP.

Most invasive insects are hidden away for the winter, but you still might encounter them when you split wood, move outdoor furniture indoors, or admire evergreen plants while on a hike.  Learn more about invasive pests you may come across and how to report them.

The Invasive Plant Atlas of the United States is a collaborative project between the National Park Service, the University of Georgia Center for Invasive Species and Ecosystem Health, the Invasive Plant Atlas of New England and the Lady Bird Johnson Wildflower Center. The purpose of the Atlas is to assist users with identification, early detection, prevention, and management of invasive plants. The focus is on non-native invasive plant species impacting natural areas, excluding agricultural and other heavily developed and managed lands. Four main components are species information, images, distribution maps, and early detection reporting procedures.
