USDA. Animal and Plant Health Inspection Service.

Based on years of experience and the latest science, APHIS developed a list of 59 pests and diseases that could pose a significant risk to U.S. food and agriculture resources. The list is not meant to be all-encompassing, but rather focus on the most impactful pests and diseases. USDA's goal remains to keep the U.S. free of these foreign pests and diseases.

Montgomery County Department of Parks (Maryland). Park Planning and Stewardship Division.

Natural Resources Stewardship staff (NRS) has determined that many non-native invasive plants (NNIs) known to present a significant threat to the quality and biodiversity of the natural areas occur in this 37,000-acre park system. To support the park mission to steward these lands, Montgomery County Department of Parks has prepared fact sheets for park managers and maintenance personnel with easy-to-read information about mechanical and chemical control methods for several terrestrial NNIs.

Louisiana Department of Agriculture and Forestry.

In May 2010 the last boll weevil was trapped in the state and in March 2012 the boll weevil was declared eradicated from the state of Louisiana. The Eradication Program is now at a maintenance level, funded through grower maintenance inspection fees. Traps are placed and monitored according to an approved trapping protocol. Cotton producers have seen increases in yields along with a reduction in the cost of insect control.

Maryland Department of Natural 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.

Vermont Agency of Natural Resources. Department of Forestry, Parks, and Recreation.
Firewood is widely recognized as a major source of non-native forest insect and disease infestations. A rule governing the importation of untreated firewood into Vermont went into effect on May 1, 2016. Visitors to Vermont State Parks, Vermont State Forests, and the Green Mountain National Forest may only bring firewood originating from Vermont or that is heat treated and in its original, labeled package. To help slow the spread of emerald ash borer within Vermont, ash firewood that has not been heat treated should not be moved outside of the Emerald Ash Borer Infested Area in Vermont.

Early Detection and Distribution Mapping System (EDDMapS), provides a more accurate picture of the distribution of invasive species. EDDMapS will allow land managers, agencies and others to set priorities for early detection and rapid response (EDRR), as well as formulate overall invasive plant management action plans. Includes distribution data by species and by county.

University of Georgia. Center for Invasive Species and Ecosystem Health.

Includes invasive species by category for insects, diseases, plants, and animals.

EDDMapS West provides a means of reporting new sightings of select invasive species in Missouri River Watershed Coalition States, a mechanism for alerting appropriate individuals to the reports, and generates distribution maps for the reported species. Available through the Apple App Store and the Google Play Store.

Vermont Invasives.

An emerald ash borer (EAB) beetle was detected in a tree located in Londonderry, VT. The mapped area in Vermont (PDF | 1.25 MB) to which "Slow-the-Spread" recommendations apply now covers:

  • All of Londonderry, Windham, and Landgrove;
  • Most of Jamaica, Winhall, Peru, Weston, Andover and Grafton; and
  • Extends into Chester, Townshend, Stratton, Athens, Mount Tabor, and Wardsboro.

October means that non-flight season Recommendations to Slow the Spread of Emerald Ash Borer are now in effect when moving ash from the infested area. With the heating season underway, and firewood deliveries actively occurring, it’s important to remember that untreated ash firewood should never move out of infested areas. Be sure that your purchase or transportation of both log length and split firewood will not unnecessarily spread EAB. There’s a lot of spread to slow: While the infested area map shows that high-risk areas for EAB include many towns, visibly infested trees still remain rare in Vermont. You can help by following the "Slow-the-Spread" recommendations.

Barataria-Terrebonne National Estuary Program.

Missouri Department of Conservation.

Report feral hogs, don't shoot them. The take of feral hogs is prohibited on conservation areas and other lands owned, leased, or managed by the Conservation Department. Hunting hogs on other lands is strongly discouraged. Instead, report feral hog sightings to 573-522-4115, extension 3296 or online. The Conservation Department and the U.S. Department of Agriculture Animal and Plant Health Inspection Service, along with other partners and hundreds of private landowners, are working to eradicate feral hogs in Missouri. When hunters shoot feral hogs, it complicates efforts to remove these pests. Hogs are social animals that travel in groups called sounders. Shooting one or two hogs scatters the sounder and makes trapping efforts aimed at catching the entire group at once more difficult, because hogs become trap-shy and more wary of baited sites. With their high reproductive rate, removing one or two hogs does not help to reduce populations. Anyone who observes a feral hog or damage caused by feral hogs should report it to the Conservation Department rather than shooting the animal so we can work together towards eradication.

National Plant Diagnostic Network.

First Detector, a program of the National Plant Diagnostic Network (NPDN), equips a nationwide network of individuals to rapidly detect and report the presence of invasive, exotic plant pathogens, arthropods, nematodes, and weeds. If you suspect the presence of a high-impact plant pest or pathogen, contact a diagnostician and submit a sample for diagnosis.

Nature Conservancy. iMapInvasives.

Includes a variety of published guides and internet resources (videos) for use in identifying invasive species that are found in the participating states, provinces, and regions of the iMapInvasives network. The iMapInvasives network is currently comprised of various U.S. states and one Canadian province (Arizona, Florida, Kentucky, Maine, New York, Oregon, Pennsylvania, Vermont, Virginia, and West Virginia, and in Canada - Saskatchewan).

Nature Conservancy. iMapInvasives.
i is an invasive species reporting and data management tool that is on-line and map-based. The primary focus for iMapInvasives is to track invasive species locations and management efforts. iMapInvasives tools can be used by citizen scientists, land owners, natural resources managers, and others who are working to prevent, control, or manage invasive species.
See also: The iMapInvasives Network is comprised of organizations that host the iMapInvasives Network database in their respective state or province.
