Wyoming Game & Fish Department.

The Wyoming Game and Fish Department is offering training for members of the public to become a certified Wyoming aquatic invasive species inspector. The free, day-long sessions are offered throughout the spring in statewide locations and are open to anyone interested in preventing the spread of AIS through watercraft inspection. The training includes information on basic biology of invasive species, the impacts of AIS, transport vectors and distribution of AIS. It includes classroom instruction, a question-and-answer session and a hands-on watercraft inspection exercise. Those who complete the class will be certified to inspect watercraft.

Herbicides are a class of pesticides used to kill or suppress weeds. This MontGuide introduces key concepts necessary for managing weeds and using herbicides safely and effectively.

With climate change, many invasive plants are projected to shift their ranges, creating hotspots of future invasions across the U.S. Knowing the identities of new invasive plants headed to a nearby state creates an opportunity for proactive prevention and management. Unfortunately, monitoring for and managing all range-shifting invasive plants is untenable. To help prioritize range-shifting species, Northeast Climate Adaptation Science Center researchers performed impact assessments on 104 plants projected to expand into one or more mid-Atlantic states by 2040 with climate change. Their study was recently published (Oct 6, 2023) in Invasive Plant Science and Management "High-impact invasive plants expanding into mid-Atlantic states: identifying priority range-shifting species for monitoring in light of climate change."

This collection of publications in NAL's Digital Repository provides access to and addresses a number of topics concerning the gypsy and the related brown-tail moths, from biological control methods to tree banding to quarantine practices. The bulk of the documents were published from 1891 to 1923 by various agencies in the area of the initial infestation, including the State Board of Agriculture for Massachusetts, New York, and Rhode Island, but also include some more modern USDA publications.

Seeds that float in the air can hitchhike in unusual places – like the air-intake grille of a refrigerated shipping container. A team of researchers from the USDA Forest Service, Arkansas State University, and other organizations recently conducted a study that involved vacuuming seeds from air-intake grilles over two seasons at the Port of Savannah, Georgia. The viability of such seeds is of significant interest to federal regulatory and enforcement agencies, and the project required a shared stewardship approach. Their findings were recently published in the journal Scientific Reports.

Seeds from 30 plant taxa were collected from the air-intake grilles, including seeds of wild sugarcane (Saccharum spontaneum), a grass on the USDA's Federal Noxious Weed List. (scroll to view list on Federal Noxious Weeds Program). Federal noxious weeds pose immediate, significant threats to agriculture, nursery, and forestry industries. Although a lovely grass and useful in its native range, wild sugarcane has the potential to join cogongrass, stiltgrass, and other nonnative species that have become extremely widespread in the U.S.
