  • Researchers Discover Undocumented Crayfish Species in Kansas

    • Jul 21, 2021
    • Kansas Department of Wildlife & Parks.

    • Widespread sampling for invasive crayfish had never occurred in Kansas lakes – that is, until the Kansas Department of Wildlife and Parks (KDWP) recently funded a university project focused on the freshwater crustacean. KDWP's Aquatic Nuisance Species Program and Ecological Services section funded the project with the overarching goal of establishing sampling protocols that could then be used for long-term monitoring of both native and invasive crayfish in Kansas. During capturing efforts at McPherson State Fishing Lake – one of several small waterbodies slated to be inspected in the state – university researchers collected multiple Rusty Crayfish. Rusty Crayfish have not previously been documented in the wild in Kansas, making this official "discovery" the first of its kind.

      Anglers, boaters and watersport enthusiasts are encouraged to keep their eyes open for this invasive species, which can be identified by its trademark large, black-tipped claws and rust-colored spots on its upper shell. If one is discovered, freeze it in a sealed plastic bag, note the date and location of capture, and contact KDWP's Emporia Research and Survey Office at (620) 342-0658.

  • Results of the 2022 Lionfish Challenge: A record-breaking year!

    • Sep 16, 2022
    • Florida Fish and Wildlife Conservation Commission.

    • The Lionfish Challenge 2022, the seventh annual, is a summer-long tournament that rewards divers for their lionfish harvests.

  • Rhode Island DEM Asks Public to be Aware of Beech Leaf Disease

    • Jul 13, 2020
    • Rhode Island Department of Environmental Management.

    • The Department of Environmental Management (DEM) is asking Rhode Islanders to monitor their beech trees for signs of leaf damage from Beach Leaf Disease (BLD). Early symptoms of BLD include dark striping on the tree's leaves parallel to the leaf veins and are best seen by looking upward into the backlit canopy. Drastic leaf loss occurs for heavily symptomatic leaves during the growing season and may appear as early as June, while asymptomatic and mildly symptomatic leaves show no or minimal leaf loss. BLD was detected in the Ashaway area of Hopkinton, Rhode Island, in 2020 and in coastal Massachusetts. Before these findings, the disease was only known to be in Ohio, Pennsylvania, New York, and Connecticut.

      Because of the seemingly random nature of disease in Rhode Island, DEM encourages homeowners and forest landowners to monitor their beech trees and report any suspected cases of BLD on DEM's Invasive Species Sighting Report webpage. Although BLD is relatively new in the U.S. and information is limited, links to additional information about the disease and photos are posted on the Division of Forest Environment's Current Threats page. If people have further questions, they should contact a licensed arborist or email Nancy Stairs, forestry program supervisor in DEM's Division of Forest Environment, via Nancy.Stairs@dem.ri.gov.

  • S.C. Anglers Should Kill Invasive Snakehead If Caught

    • Oct 25, 2019
    • South Carolina Department of Natural Resources.

    • South Carolina Department of Natural Resources officials are warning anglers that if the invasive Northern snakehead fish is caught in the Palmetto State, anglers should kill it immediately and by all means NOT release it back into the water. In early October, a Georgia angler reported catching a Northern snakehead, an aquatic invasive species, in a pond located on private property in Gwinnett County, Ga. This is the first time the Northern snakehead has been confirmed in Georgia waters. In the Southeast, Northern snakeheads have also been found in North Carolina and Florida. If you believe you have caught a Northern snakehead:

      • DO NOT RELEASE IT
      • Kill it immediately (remember, it can survive on land) and freeze it.
      • If possible, take pictures of the fish, including closeups of its mouth, fins and tail.
      • Note where it was caught (waterbody, landmarks or GPS coordinates).
      • Report it to the SCDNR by calling 1-800-922-5431.
  • San Diego Area Agencies Responding to Discovery of Invasive Seaweed in San Diego Bay

    • Nov 16, 2023
    • Port of San Diego (California).

    • The Port of San Diego, along with the Southern California Caulerpa Action Team (SCCAT), the City of Coronado, and the Coronado Cays Homeowners Association (CCHOA), are responding to the discovery of an invasive seaweed scientifically known as Caulerpa prolifera in the Coronado Cays area of San Diego Bay.

      In late September, divers found a small patch of Caulerpa prolifera while conducting an in-water pre-construction eelgrass/Caulerpa dive survey as a permit condition for a dock replacement project. Additional patches were discovered nearby during follow-up surveys. The total find within the Cays is about one-quarter of an acre. The SCCAT has prepared a Rapid Response Eradication Plan to address the immediate need to eradicate this invasive species.

  • Seek and Destroy: The Spotted Lanternfly

    • Oct 18, 2019
    • Maryland Department of Natural Resources.

    • Spotted lanternfly is a threat to Maryland and the U.S. The Maryland Department of Agriculture issued a quarantine October 28, 2019 in an effort to contain the invasive species in Cecil and Harford counties after the spotted lanternfly was spotted in Cecil’s northeastern corner and along Harford’s northern border. See additional resources on the Maryland Department of Agriculture's site for Spotted Lanternfly for up-to-date information.

      For questions related to the quarantine, permitting, treatment, or to report a sighting of the spotted lanternfly, especially outside of the quarantine zone, call 410-841-5920 or email DontBug.MD@maryland.gov. If you report a spotted lanternfly via email, please provide the location of the sighting and your contact information.

  • Snake River Quagga Mussel

    • Idaho Department of Agriculture.

    • The Idaho Department of Agriculture (ISDA) has confirmed the presence of quagga mussel in the Mid-Snake River. Quagga mussel larvae was first detected in the Snake River near Twin Falls on September 18, 2023, by routine monitoring conducted by the ISDA. If nothing were done, quagga mussels would quickly take over waterways. They would irreparably harm water use in Idaho. These findings mark the first time a rapid response plan has been put into action for quagga mussels in Idaho.

  • Spongy Moth Population Increases for Third Consecutive Year in Wisconsin

    • Dec 2, 2022
    • Wisconsin Department of Agriculture, Trade, and Consumer Protection.

    • The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) caught 202,300 spongy moths (formerly named gypsy moth) in 10,044 traps this summer as part of the federal Slow the Spread of the Spongy Moth Program. "Wisconsin weather trends have allowed the spongy moth population to grow over the last several years," said Michael Falk, DATCP's trapping coordinator.

      Spongy moth is an invasive pest that has been spreading westward since its introduction to North America. Caterpillars feed on the leaves of many species of trees and shrubs, especially oaks, and can cause severe leaf loss when feeding in large numbers. For more information, call (800) 642-MOTH (6684), email spongymoth@wisconsin.gov, or visit www.spongymoth.wi.gov.
