Tracking the establishment and spread of existing and new invasive species is critical to effectively manage invasive species. In addition to standard means of monitoring, the USGS is developing new tools, particularly molecular techniques, to assist in the early detection of invasive species. Provides research information about eDNA and Genetic Tools for Zebra and Quagga Mussels.

Laurel wilt disease has been spreading through the U.S. since 2002 and is fatal to tree species in the laurel family. Forest Service researchers are continuing to monitor the disease, search for treatment methods, and develop a better understanding of how it is affecting sassafras and other susceptible species.

The Chesapeake Bay Nutria Eradication Project (CBNEP) historically used working dogs to locate invasive nutria populations across the Delmarva Peninsula. As nutria populations decreased, the transition to detection and detector dogs was necessary. Dogs can be trained to smell the evidence of specific animals and plants in an area without visual identification.  

Are you a crabber, waterman, or concerned citizen? We need your help to detect and assess the status of Chinese Mitten Crabs. The "Mitten Crab Watch" website provides information on the invasion of the mitten crab and allows users to more easily report catches.

Please help us detect live mitten crabs by reporting any sighting in North America. We are especially interested in collecting sightings from the Chesapeake Bay, Delaware Bay, Hudson River, and San Francisco Bay --- where the crab has been common in the past. Please visit the Mitten Crab Watch website to learn more about the crab and to report sightings.

Forests are complex ecosystems. They are constantly changing as a result of tree growth, variations in weather and climate, and disturbances from fire, pathogens, and other stressors. A huge number of insects and diseases have the potential to negatively affect tree species in the U.S. 

The Forest Health Monitoring (FHM) Program produces annual national reports that present forest status and trends from a national perspective, introduce new techniques for analyzing forest health data, and summarize results from recently completed Evaluation Monitoring projects funded through the FHM national program.  The FHM tracks these ongoing changes — every year, across the nation — as a forest health check up. The annual reports contains short- and long-term forest health assessments for the continental U.S., Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands. Users can search reports and chapters by year (from 2001) or topic. Highlights and additional resources are also included.

Includes first date of Asian longhorned tick detections by state, county, and host.

The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has developed a publicly available dashboard that displays the results from nation-wide avian influenza virus (AIV) monitoring in wild bird populations. Data presented in the dashboard can identify increased AIV risk and can provide information to poultry producers, wildlife managers, and members of the public on AIV activity in their area.

Environmental DNA methods are highly sensitive and accurate, making them ideal for detecting animals at low densities. However, this tool also comes with its own unique set of challenges when applied to efforts to eradicate invasive species. This research explores the use of eDNA for evaluating invasive species eradication efforts in streams and offers best practices for incorporating eDNA methods into invasive species removal projects.

Provides fact sheets, maps and collection information for aquatic vertebrates and invertebrates occurring outside of their native range.

These maps were created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with storms. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and/or creation of freshwater bridges along coastal regions. These maps will help natural resource managers determine potential new locations for individual species, or to develop a watchlist of potential new species within a watershed.
