The U.S. Geological Survey Ecosystem Mission Area plays a major role in invasive snake science across the country and the globe, ranging from research on improving snake detection to projects that enhance eradication. Our extensive science ultimately scales up to benefiting public health, energy transmission, tourism, and other key aspects of American prosperity.

Early detection equals stronger protection. DNA in the environment is the front line against invasive species.

The USGS is a pioneer in environmental DNA (eDNA) science, applying cutting-edge molecular tools to identify, detect, or track species, monitor ecosystems, and safeguard biodiversity.

The U.S. Geological Survey Southwest Biological Science Center (SBSC) is uniquely positioned in the Colorado River Basin to provide sound information, specialized expertise, and innovative tools to support the management and sustained use of natural resources on public and Tribal lands in the Southwest U.S.

Scientists at USGS have shown that much of the US is suitable for invasion by tegu lizards, and suitability will likely increase in the future. While tegus can be removed via trapping, it is difficult to monitor every geographic area where tegus could invade. Thus, methods for quickly detecting and removing tegus in new areas are the best way to prevent spread and minimize damage from these...

Since Public Law 109-148, USGS has partnered with state and federal agencies to conduct science to support the national response to highly pathogenic avian influenza (HPAI). In 2014, the first reports of HPAI in US wild birds came from USGS cause-of-death investigations confirmed by the USDA.

Due to the rapid decline in abundance of Yellow Lampmussel ( Lampsilis cariosa) and Tidewater Mucket ( Atlanticoncha ochracea), USGS and partners at the U.S. Fish and Wildlife Service (USFWS) and Central Michigan University (CMU) are conducting an assessment of genetic diversity and population structure to inform appropriate recommendations for conservation and management of each species. These...

New terrestrial environmental DNA (eDNA) sampling techniques are sensitive tools for early detection of the highly invasive brown treesnakes (BTS). In a new collaborative research effort involving four USGS science centers, scientists have initiated the development of an innovative point-of-use (POU) assay for BTS. POU assays are tests that can be run in the field with minimal equipment and no...

Siren: the National Early Detection and Rapid Response (EDRR) Information System is an online resource for invasive species information sharing and collaboration that serves as the information hub of the National EDRR Framework.

European green crabs are one of the most widespread marine invasive species on the planet. Where they are abundant, green crabs compete with other crabs and disturb sediment which can lead to loss of eelgrass and associated habitat essential for commercial, cultural, and ecologically important fish and invertebrate species. Green crab also are a major predator of clams, mussels, and oysters.

The coronavirus pandemic, Chronic Wasting Disease (CWD) in white-tailed deer, and white-nose syndrome in bats have spawned great interest in diseases of native fish and wildlife. Many aspects of widely known diseases of wild (as opposed to domestic) animal populations are poorly understood, including their ecology, incidence, distribution, and methods for reducing effects of disease on culturally...

The USGS has developed the Rapid environmental (e)DNA Assessment and Deployment Initiative & Network (READI-Net) to accelerate the implementation of environmental DNA (eDNA) analysis as a best practice for the early detection of aquatic biological threats. READI-Net provides tools and a strategy to collect and deliver early detection data for natural resource managers and public health protection...
