Resource Search

In 2019, the Alaska Office of the State Veterinarian, in collaboration with the Alaska Department of Fish and Game and the University of Alaska, began the Alaska Submit-A-Tick Program. Through this program, individuals who find ticks on themselves, their family members, pets, or wildlife (e.g. hunted or trapped animals) can submit ticks for species identification and pathogen testing. Researchers are asking Alaskans to submit ticks to help determine which tick species are currently in the state. Tick submissions will also help us learn more about how ticks are being imported into Alaska so that we can create effective strategies to limit their introduction. Ticks can transmit bacteria, parasites, and viruses that can cause diseases in humans and wildlife. Pathogen testing allows us to assess tickborne disease risk in the state.

Colorado Parks and Wildlife (CPW) announces additional zebra mussel veligers found in the Colorado River and Government Highline Canal after increased testing. With these additional detections, both the Highline Government Canal and the Colorado River meet the criteria for being considered “positive” for zebra mussels.

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.

Quagga mussels were found in the Snake River in September 2023. Immediately afterwards, Idaho Fish and Game assisted the Department of Agriculture in their evaluation of potential treatments to eliminate the mussels, and Idaho Fish and Game quantified the fish populations found in the six-mile stretch of river where the mussels were found, and where the treatment would occur. Biologists quickly learned that the treatment caused high mortality in certain species, while others survived quite well.

"Help Stop the Pop", MFC's popcorn tree control program, aims to track popcorn trees, assist municipalities with popcorn tree control, and educate landowners about proper tree removal. Chinese tallow trees, also known as the popcorn tree, are deceptive. They look attractive and ornamental, but they are actually highly invasive and will quickly damage the native ecosystem wherever they are planted. By reporting the location of these trees, you can help the Mississippi Forestry Commission (MFC) get a full picture of Mississippi's popcorn tree problem, which is the first step to combating the spread of this invasive species. Help the MFC stop the spread of this invasive species. Report sightings to HelpStopThePop.com. More Information visit the MFC's Chinese Tallow Tree information page.

Divers monitoring Lake Tahoe have discovered invasive New Zealand mudsnails in areas off the South Shore, the Tahoe Regional Planning Agency (TRPA) and Tahoe Resource Conservation District (Tahoe RCD) announced today. This is the first time the species has been detected in the Tahoe Basin.

Following rapid response protocols under the federally approved Lake Tahoe Aquatic Invasive Species Management Plan, TRPA convened an incident team comprised of staff from TRPA and Tahoe RCD and partner experts. The team is rapidly deploying scientists, beginning with lake-wide dive surveys to determine the extent of the infestation and sharing all available information with state and federal wildlife managers through the Lake Tahoe Aquatic Invasive Species Coordinating Committee. Get up-to-date information on the response and potential protocols for management of the infestation on the TRPA New Zealand mudsnail page.

The Washington State Department of Agriculture (WSDA) is beginning its annual search for pests that could threaten the state’s environment and agricultural industry. Staff will set thousands of traps statewide to monitor for the introduction or spread of more than 130 invasive pests and diseases, including spongy moth, Japanese beetle, apple maggot and northern giant hornet.

WSDA is still asking residents to report all suspected hornet sightings. Northern giant hornet queens should be active now and could be spotted while they establish their nests. As the colony grows, worker hornets may become increasingly visible throughout the summer and into the fall. See Public hornet trapping instructions for more information.

On August 5, the Washington Department of Fish and Wildlife (WDFW) received notification from a local wholesale aquarium company in Renton of possible invasive freshwater mussels on a shipment of Marimo moss balls (Aegagropila linnaei). Moss balls are a commonly used decorative algae in aquariums and water gardens. Lab testing confirmed the mussels were zebra mussels (Dreisena polymorpha), a prohibited aquatic invasive species in Washington that, if established in local waters, would be capable of causing significant infrastructure and environmental damage. Zebra mussels and a close relative, the quagga mussel, are not known to be established in Washington.

We need your help to monitor for and report northern giant hornet sightings. By participating in a northern giant hornet citizen scientist project, you are helping protect your community from northern giant hornets.

Since the first report of a northern giant hornet in Washington in 2019 (known as the Asian giant hornet or the “murder hornet” back then), the Washington State Department of Agriculture’s (WSDA) Pest Program has been working to eradicate northern giant hornets. The best time to participate is from July through November. You are most likely to see or catch a northern giant hornet during this timeframe because colonies are established, and workers are out hunting.
