Agricultural Research Service (ARS) and the Weed Science Society of America (WSSA) are co-hosting 10 webinars on weed science and research, with a focus on impacts from weeds and invasive plants.

Beginning April 5, weekly presentations will be given by ARS weed science research experts. The webinars will occur every Tuesday from 2-3p.m. Eastern Time (ET) and include an interactive Q&A session. The webinar series is open to the public. Webinars are recorded and available to view on demand.

Includes final annual and cumulative maps and data from 1999 to 2024.

The Invasive Species Data Mobilization Campaign of the Western Governors’ Association seeks to encourage national, state, and local land managers, private landowners, and non-governmental organizations to enter previously unavailable data into new or existing invasive species data management platforms using Findings and Recommendations (May 15, 2018) [PDF, 244 KB] developed by WGA and invasive species data experts. WGA and the North American Invasive Species Management Association launched the campaign in December 2020 with a webinar featured representatives from the four existing data platforms -- EDDMapS, iMapInvasives, BISON (see note below), and USGS NAS -- discussing the importance of invasive species data standardization and sharing.
Note: GBIF-US was formerly hosted at BISON.USGS.gov. The BISON website was taken down on December 17, 2021 and users are redirected to www.gbif.us.

You can help with efforts to control invasive species by reporting occurrences of invasive species. The information provided can help you know what information to report and which method of reporting to choose.

Learn about some of the common species of wasps, bees and other non-wasp species, such as hover flies and robber flies, that superficially resemble the Asian giant hornet.

The Mississippi River Delta is home to the world’s largest contiguous swath of Phragmites australis, or more commonly known as the common reed. But the plant that can grow to nearly 20 ft. and has been a critical component in stabilizing the state’s coastal erosion is not actually native to Louisiana—well, not entirely. There are multiple P. australis genotypes. P. australis subspecies (ssp.) americanus is the native subspecies in the U.S. and Canada. However, Phragmites australis ssp. australis originated in central Europe and was subsequently introduced to the U.S. where it is now considered to be one of the most problematic invasive species in North America. "Novel genome characteristics contribute to the invasiveness of Phragmites australis (common reed)" in Molecular Ecology and recently featured in an edition of The Scientist, LSU researchers collaborated with Tulane University and the U.S. Geological Survey to study the genomic bases of P. australis and to investigate what exactly makes the invasive reed grass subspecies thrive in wetlands, in comparison to its native counterpart.

A chance discovery in an Ohio woodland has turned into a multi-disciplinary, multi-agency, and multi-national effort to piece together a puzzle and understand a scourge that is killing trees by the thousands in northern states east of the Great Plains. The leaves of young beech trees are failing somehow. Scientists have figured out what causes the malady; it’s the 'how' that has them scratching their heads. Beech trees are one of the most common trees in America's northern and northeastern forests. Their nut crop feeds birds and other animals, and its wood is prized for bentwood furniture. The symptoms of beech leaf disease were plain to see – sunken dark spots on the leaves, which eventually died – but opinions differed on the cause. Was it bacterial, fungal, or viral? Then, a plant pathologist working for the State of Ohio noticed wiggly things in the leaf lesions. They turned out to be nematodes, microscopic worms that live in the soil, that had somehow managed to make it to the tree canopy 40-50 feet above ground. Nematode samples were sent to Beltsville, MD, for analysis and identification at the Agricultural Research Service (ARS) Mycology and Nematology Genetic Diversity and Biology Laboratory in Beltsville, MD. The nematode, Litylenchus crenatae, turned out to be native to Japan – the first population of L. crenatae found in the Western Hemisphere. The curious thing is that it's not a tree-killer in Japan.

Emerald ash borer, laurel wilt disease, thousand cankers disease, and the European gypsy moth are likely to be brought into North Carolina in or on firewood. The use of local firewood is an important factor in preventing the spread of potentially devastating invasive species to our state's forests. Please keep this in mind as you prepare for your outdoor recreation activities. See Forest Health Invasive Pest Maps for more information about pest monitoring.

WHISPers, a Wildlife Health Information Sharing Partnership event reporting system with current and historic information on wildlife morbidity or mortality events in North America. Events typically involve five or more sick or dead wild animals observed in the same general location and time period. This information is collected opportunistically and provided here by multiple State, Federal, and other agencies to enhance collective understanding of disease in wildlife populations.
