Invasive zebra and quagga mussels alter ecosystem dynamics and affect industrial, municipal, and recreational water users. The negative impacts of these dreissenid mussels drove scientists to search for effective control methods beginning in the early 1990s. Since then, researchers have uncovered various control methods, each with their own advantages and disadvantages. Both chemical and physical treatments have been developed and used by state and federal agencies in the control of zebra mussels.

Looking for answers to your mussel questions? Interested in funding opportunities and compliance requirements for research? Want more information about management and control of mussels? There are a variety of experts within the Invasive Mussel Collaborative ready to answer whatever questions you may have!

The Invasive Mussel Collaborative announced today that it has released a new strategy to reduce invasive mussels and their negative impacts. The Strategy to Advance Management of Invasive Zebra and Quagga Mussels is intended to drive investments, policy, and research around invasive mussels across the Great Lakes region and beyond. Since their initial discovery in 1989, zebra and quagga mussels have had dramatic impacts on the Great Lakes ecosystem and economy, including changes to the food web, degrading fish habitat, interfering with drinking water systems and damaging tourism and recreation economies. Today, these mussels continue to spread to new water bodies across the U.S. and Canada.

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.

Provides information for plant species reported to be invasive in natural areas in the U.S. 

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.
