The Pennsylvania Fish and Boat Commission (PFBC) announced that it has conducted targeted invasive carp sampling in Presque Isle Bay, Erie County, after the U.S. Fish and Wildlife Service (USFWS) detected the presence of Silver Carp environmental DNA (eDNA). While no physical invasive carp specimens have been detected, the PFBC has requested that the USFWS collect additional water samples from Presque Isle Bay in the fall when more favorable environmental conditions are present for eDNA sampling. Members of the public can report sightings of aquatic invasive species to the PFBC using its online form.
Environmental DNA (eDNA) has gone from new science on the block to a star of the show. With just a water, soil, or snow sample, ecologist Tommy Franklin and fellow scientists at the Rocky Mountain Research Station are detecting rare aquatic and terrestrial species by identifying the genetic material they leave behind.

This site was created with funding from the Department of Defense Environmental Security Technology Certification Program (ESTCP) and DoD Legacy Resource Management Program. It's currently managed by Washington State University with a mix of content that was created by WSU for the site as well as eDNA resources contributed by the eDNA research community.
The emerald ash borer (EAB) is a highly destructive invasive beetle which attacks and kills all species of ash, but not mountain ash, which in spite of its name, is a completely different species of tree. To help prevent the spread of EAB, the movement of ash logs and firewood out of regulated areas is restricted. Report any detections outside of regulated areas to the Canadian Food Inspection Agency (CFIA).
Environmental DNA (eDNA) is the genetic material from a plant or animal that is found in the air, water or soil. Fish, such as invasive carp, release DNA into the environment in the form of skin cells, secretions, and feces. This DNA can be collected from water samples in the field and be used to indicate the potential presence of an individual species. eDNA testing is useful as a potential early indicator of invasive carp presence and was developed to improve monitoring of such aquatic invasive species.
Environmental DNA is developing into a powerful tool for improving the monitoring and detection of invasive species, which may be present in low numbers and therefore difficult to find. There are a wide range of ongoing efforts by federal and non-federal groups working to improve and apply eDNA to invasive species monitoring and management.
The NISC FY2020 to FY2022 Work Plans incorporated interagency work on eDNA, including the following outputs:
Assays of environmental DNA — traces of genetic material found in air, soil, and water — may improve scientists’ ability to detect bat roosts and track the spread of white-nose syndrome, a disease caused by a killer fungus spread easily in the close quarters of hibernacula. In this research, scientists experienced success in detecting bats in field collected samples of environmental DNA, though the technology is still in the experimental stage.
United States Geological Survey Science is Refining eDNA Techniques and Developing New Applications. Research by the U.S. Geological Survey is leading to new techniques in the use of environmental DNA, or eDNA, to detect invasive species and their spread.
CDC's estimated range maps for Ae. aegypti and Ae. albopictus mosquitoes were developed by using a model that predicts possible geographic ranges for these mosquitoes in the contiguous United States. The model used county-level records, historical records, and suitable climate variables to predict the likelihood (very low, low, moderate, or high) that these mosquitoes could survive and reproduce if introduced to an area during the months when mosquitoes are locally active.
The Invaders of Texas Program is an innovative campaign whereby volunteer "citizen scientists" are trained to detect the arrival and dispersal of invasive species in their own local areas. That information is delivered into a statewide mapping database and to those who can do something about it. The premise is simple. The more trained eyes watching for invasive species, the better our chances of lessening or avoiding damage to our native landscape.
The U.S. Fish and Wildlife Service and U.S. Geological Survey have signed a memorandum of understanding formalizing their joint leadership of the North American Bat Monitoring Program (NABat), a collaborative partnership focused on advancing bat conservation across North America. As co-leads of the NABat program, the two federal agencies will work to ensure the program remains sustainable and meets the needs of partners by providing coordination, technical assistance, data products and analyses that make it easier to apply bat monitoring data more effectively in support of conservation. For more information about the North American Bat Monitoring Program and opportunities to participate, please visit https://www.nabatmonitoring.org.
NABat was born out of the urgent need to monitor bat populations following the emergence of white-nose syndrome, a disease of hibernating bat species that appeared in New York in 2007 and has since spread across the continent. White-nose syndrome is considered one of the worst wildlife diseases in modern times, resulting in the loss of millions of bats across North America.
