Chinese privet (Ligustrum sinense) is one of the worst invasive plants in the South. It dominates the shrub layer and often becomes the only shrub underneath trees, especially in streamside areas. But insects and spiders living in fallen leaves and leaf litter were not affected by a privet invasion in Georgia, as a recent study shows.

Montana’s economy could see more than $230 million in annual mitigation costs and lost revenue if invasive mussels become established in the state, according to a report released by the Montana Invasive Species Council (MISC). Commissioned by MISC and completed by the University of Montana Flathead Biological Station, the economic impact study provides “a snapshot of projected direct costs to affected stakeholders dependent on water resources,” said Bryce Christiaens, MISC chair. “It does not reflect the total economic impact to the state, which would be considerably higher.” View a one-page fact sheet (PDF | 484 KB) or the full report (PDF | 4.0 MB).
Learn to edit Wikipedia and help improve articles about invasive species. Join the National Agricultural Library’s National Invasive Species Information Center to learn more about invasive species, their impacts, and their control.
The event scheduled from 11am-3pm will begin with an introduction and information about the Information Center and invasive species from Joyce Bolton, head of the National Invasive Species Information Center, and other guest speakers. Then, Jamie Flood, Wikipedian-in-residence of National Agricultural Library and Ariel Cetrone of Wikimedia D.C. will lead a one-hour training on Wikipedia editing and we will spend the rest of the day updating invasive species articles on Wikipedia. During the event experienced editors will be on hand to assist and answer questions.
International Union for the Conservation of Nature.
IUCN has launched a global standard for classifying the severity and type of impacts caused by alien species, known as the Environmental Impact Classification for Alien Taxa (EICAT). This tool will alert scientists, conservation practitioners and policy makers to the potential consequences of invasive alien species, guiding the development of prevention and mitigation measures.

New research by NOAA and partners finds that two species of invasive Asian carp -- the bighead carp and silver carp, collectively known as bigheaded carps -- could be capable of establishing populations in Saginaw Bay, Lake Huron and affecting the health of ecologically and economically important fish species such as yellow perch. The research, appearing online in the journal Biological Invasions, is based on a new model that simulates interactions between the bigheaded carps and a range of fish species, including walleye, yellow perch, and groups lower on the food web over a time period of 50 years. Over 180 non-indigenous aquatic species have already become established in the Great Lakes, with a handful of these producing substantial negative impacts. While bigheaded carps are established in watersheds near the Great Lakes, they have not yet become established in the Great Lakes.

USDA Forest Service scientists are exploring the impacts of invasive species in forests and rangelands of the United States and developing early intervention strategies that land managers can take as well as strategies for restoring impacted landscapes.

White-nose syndrome has killed over 90% of northern long-eared, little brown and tri-colored bat populations in fewer than 10 years, according to a new study published in Conservation Biology. Researchers also noted declines in Indiana bat and big brown bat populations. The findings, detailed in "The scope and severity of white-nose syndrome on hibernating bats in North America," underscore the devastating impacts of the deadly fungal disease. The research tapped into the most comprehensive data set on North American bat populations to date, which includes data from over 200 locations in 27 states and two Canadian provinces.
