Invasive Species Resources

The Maryland Department of Agriculture has confirmed the first spotted lanternfly hatch of 2020. The first instar nymph of the season was reported by a department employee while surveying for the pest in the upper northeast corner of Cecil County near the Pennsylvania 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.

Reflecting his goal of making Wyoming a national leader in the battle against invasive species, Governor Mark Gordon announced today he has launched an initiative to address terrestrial invasive plants in the state. The initiative will be comprised of two teams -- a Policy Team and a Technical Team, each comprised of local, state and federal government representatives, private citizens representing industry and agricultural groups, as well as scientists and practitioners. The two teams will work cooperatively to develop recommendations for the Governor in the context of a large-scale strategy for invasive species management. Terrestrial invasive species represent a significant threat to Wyoming’s forests, rangelands and agricultural lands with varying levels of impact.

This guide is intended to assist with identification of invasive plants and provide information on controlling these problem plants. Included are both non-chemical means of control as well as information on proper use of herbicides where chemical controls are needed. The choice of control measure depends on the size and nature of the infestation. If dealt with early enough, invasive plant problems can often be eliminated by non-chemical methods. However, a herbicide-based approach may be required to control an infestation that has become well established or widespread.

Idaho watercraft inspectors have identified  zebra mussels on a commercially hauled sailboat destined for Lake Coeur d’Alene in the state’s northern panhandle, marking the first time the invasive species has been found live this year.

Wisconsin's recently revised aquatic invasive species (AIS) management plan is now final and available for use by the public after receiving approvals from the National Aquatic Nuisance Species Task Force. Wisconsin last completed an AIS management plan in 2002. Wisconsin's AIS management plan serves multiple purposes, including maintaining Wisconsin's eligibility for funding and directing the AIS efforts of the DNR and partner groups. The new plan also introduces an invasion pathway management approach that will help Wisconsin systematically limit how invasive species move into and throughout Wisconsin. The plan can be downloaded here (PDF | 3.89 MB).
