Early Detection and Rapid Response

The National Early Detection Rapid Response (EDRR) Information System is an emerging online resource for invasive species information sharing and collaboration that serves as the information hub of the National EDRR Framework. This centralized network will improve access to existing and emerging information resources and expand collaboration to facilitate early detection and rapid response to...

Many managers are hampered by the scope of the invasive species problem compared to their available resources. Habitat suitability models of invaders can help fill this resource gap, helping with activities such as watch list compilation and targeted surveillance and eradication efforts.

The Coronavirus Aid, Relief and Economic Security Act (CARES Act) was signed into law on March 27th, 2020, to aid response efforts and ease the economic impact of COVID-19. The Department of the Interior received funds to “prevent, prepare for, and response to coronavirus, domestically or internationally including, “biosurveillance of wildlife and environmental persistence studies.” The USGS...

USGS researchers are working with the Monterey Bay Aquarium Research Institute to optimize autonomous, robotic samplers for detection of DNA fragments shed by biological threats (BT; invasive species, parasites, pathogens) in our nation’s waters. Finding DNA fragments (a method known as environmental DNA sampling) produced by an emerging BT in water is akin to finding a needle in a haystack—many...

USGS WARC works with partners on early detection and rapid response (ED/RR) efforts, rapidly removing newly introduced non-native marine fishes from Florida’s coastal waters to prevent invasions.

ʻŌhiʻa (Metrosideros polymorpha) is the dominant tree in Hawaiian forests, but Rapid ʻŌhiʻa Death (ROD), a newly emerging disease that stands to cause high mortality of this ecologically important tree, may lead to invasions by exotic plants as gaps open in the forest. To better understand if planting of ʻōhiʻa seedlings can be used as a restoration tool, we investigated the survival of ʻōhiʻa...

WHISPers, the Wildlife Health Information Sharing Partnership - event reporting system, is a partner-driven, web-based repository for sharing basic information about historic and ongoing wildlife mortality (death) and/or morbidity (illness) events. The information, such as county-level locations, onset and ending dates, species affected, and diagnosis has generously been shared with the USGS...

Melaleuca is an invasive tree that is highly problematic in the Everglades, threatening native wildlife and habitat. USGS is helping to improve management strategies for the invasive plant.

A requirement for managing a species, be it a common native species, a species of conservation concern, or an invasive species, is having some information on its distribution and potential drivers of distribution. Branch scientists have been tackling the question of where these types of species are and where they might be in the future.

USGS scientists and staff associated with the Brown Treesnake Project are co-located at the Guam National Wildlife Refuge at the northern end of Guam in the western Pacific Ocean. Project staff work on developing and testing control tools for invasive brown treesnakes, as well as understanding their impacts on Guam's ecosystems. Project staff also lead the multi-agency Brown Treesnake Rapid...

Environmental DNA (eDNA) is organismal DNA that can be found in the environment. Environmental DNA originates from cellular material shed by organisms (via skin, excrement, etc.) into aquatic or terrestrial environments that can be sampled and monitored using new molecular methods. Such methodology is important for the early detection of invasive species as well as the detection of rare and...

Brown Treesnakes continue to cause major problems for the ecology, economy, and quality of life on Guam. Our scientists conduct research on this snake species, including control tool development and testing, ecological impacts, and early detection methods. We hold Brown Treesnake Rapid Response Team training courses on Guam throughout the year to develop the skills needed to effectively respond to...
