Building on information provided by federal agencies and an inspection of the US Code and the Code of Federal Regulations, this article reviews and identifies relevant authorities to determine federal legal capacities, gaps, and inconsistencies to address (Early Detection and Rapid Response (EDRR). Although the Plant Protection Act and the Animal Health Protection Act are comprehensive authorities that address the detection of and response to organisms that threaten plant and livestock health, there is no single authority that encompasses EDRR for all invasive species. Rather, there is a patchwork of authorities that unevenly addresses various aspects of EDRR. View Early Detection and Rapid Response for more information.

Japanese stiltgrass (Microstegium vimineum), also called Nepalese browntop, is an aggressive invader of forest lands throughout the eastern United States. Infestations can impact the diversity of native species, reduce wildlife habitat, and disrupt important ecosystem functions. Stiltgrass is considered one of the most damaging invasive plant species in the United States. Infestations spread rapidly and the seed can remain viable in the soil for up to five years. Correct identification is necessary before beginning any management activities. Fortunately, Japanese stiltgrass has a unique combination of characteristics that make field identification possible. This publication gives simple descriptions and clear pictures of these characteristics along with details on how to distinguish several common look-a-like species.

Hydrilla, considered one of the world's most invasive aquatic plants, has been detected for the first time in Michigan. The Department of Environment, Great Lakes and Energy confirmed two small populations of the plant in adjacent private ponds on residential properties in Berrien Springs in Southwest Michigan.

The small patches of hydrilla (Hydrilla verticillata) were discovered during routine monitoring following treatment for another invasive plant, parrot feather, which was found in the pond in 2020. Both species are prohibited in Michigan, meaning it is unlawful to sell, possess or import them into the state, and both are on Michigan’s invasive species watch list due to their potential environmental threat. Any suspicious aquatic plants should be reported as soon as possible to EGLE-WRD-AIP@Michigan.gov. Include close-up photos and provide the location of the detection in your report. More information on identifying and reporting invasive aquatic plants can be found at Michigan.gov/Invasives.

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.

FLIP (Florida Invasive Plants) is designed to be a mobile field guide that can be accessed by a computer, smart phone, tablet, or other device with internet browser capability. Developed in partnership with the University of South Florida (USF), FLIP currently contains 20 plants: 19 of the 2011 Category I invasive species and one of the 2011 Category II invasive species, as designated by the Florida Exotic Pest Plant Council (FLEPPC).

"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.
