The Georgia Department of Natural Resources' Wildlife Resources Division confirmed someone found a northern snakehead in early October in a pond on private property in Gwinnett County, marking the first time the invasive fish has been found in the state. Fishermen who find a northern snakehead should take pictures, note where it was caught and then report it.
ARS scientists in Nevada, studied ways to control cheatgrass and restore rangelands to a healthy mix of plants, which in turn reduces wildfire threats, supports wildlife, and increases sustainable grazing resources.
A map identifying the areas suitable for establishment of the spotted lanternfly (SLF) in the United States and other countries has been published in the Journal of Economic Entomology by Agricultural Research Service scientists. The SLF, originally from China, has spread to Korea and Japan, and has been found most recently in the United States in Pennsylvania, New Jersey, Virginia and Delaware. These insects are pests of many agricultural crops including almonds, apples, blueberries, cherries, peaches, grapes and hops as well as hardwoods such as oak, walnut and poplar, among others. USDA and State partners have been working to contain SLF populations since 2014. There is the potential for far reaching economic damage if the SLF becomes widely established in the United States.
Reflecting his goal of making Wyoming a national leader in the battle against invasive species, Governor Mark Gordon announced today he has launched an initiative to address terrestrial invasive plants in the state. The initiative will be comprised of two teams -- a Policy Team and a Technical Team, each comprised of local, state and federal government representatives, private citizens representing industry and agricultural groups, as well as scientists and practitioners. The two teams will work cooperatively to develop recommendations for the Governor in the context of a large-scale strategy for invasive species management. Terrestrial invasive species represent a significant threat to Wyoming’s forests, rangelands and agricultural lands with varying levels of impact.
Wisconsin's recently revised aquatic invasive species (AIS) management plan is now final and available for use by the public after receiving approvals from the National Aquatic Nuisance Species Task Force. Wisconsin last completed an AIS management plan in 2002. Wisconsin's AIS management plan serves multiple purposes, including maintaining Wisconsin's eligibility for funding and directing the AIS efforts of the DNR and partner groups. The new plan also introduces an invasion pathway management approach that will help Wisconsin systematically limit how invasive species move into and throughout Wisconsin. The plan can be downloaded here (PDF | 3.89 MB).
The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) is proposing to lift the domestic quarantine for pine shoot beetle. Despite efforts to control pine shoot beetle since it was first detected in 1992, this pest, which only infests stressed and dying pine trees, is now found in 20 states in the northeast and north central parts of the country. Given the limited impact of interstate movement restrictions on the beetle’s spread and the minimal damage this pest has caused to native pines, plantations, and nursery trade, we are proposing to remove the pine shoot beetle domestic quarantine. This action would allow the states to determine the best approach for managing the pest within their boundaries, relieve impacted businesses and individuals from having to comply with costly and burdensome restrictions, and allow APHIS to focus limited federal resources on higher risk pests. APHIS will carefully consider all comments received. Beginning Monday, members of the public will be able to submit comments for 60 days, or until November 22, 2019 at: https://www.regulations.gov/docket?D=APHIS-2016-0065
The U.S. Department of the Interior has renewed its support for the Northeast Climate Adaptation Science Center (NE CASC) at the University of Massachusetts Amherst with a five-year, $4.5 million commitment as the host campus for its six-member consortium of universities, says center co-director professor Richard Palmer. Scientists affiliated with the center provide federal, state and other agencies with region-specific results of targeted research on the effects of climate change on ecosystems, wildlife, water and other resources. The new agreement continues Interior’s original seven-year, $11 million grant to the NE CASC at UMass Amherst that began in 2011. One of the web-based tools created by the NE CASC is the Regional Invasive Species and Climate Change (RISCC) Management project, which helps invasive species managers through working groups, information-sharing and targeted research.
Florida is a national and global hot spot for non-native, invasive species. Because researchers and land managers in Florida have been dealing with invasive species for decades, there is an abundance of resources available to the public regarding invasive species. Sometimes, the volume of available information can be confusing. There are five different primary lists of non-native plant species that are referenced in Florida: 1. The Federal Noxious Weed List, 2. The Florida Noxious Weed List, 3. The Florida Prohibited Aquatic Plant List, 4. The Florida Exotic Pest Plant Council (FLEPPC) Plant List, and 5. The UF/IFAS Assessment of Non-Native Plants. This document aims to inform the general public, land managers, researchers, local and state policy makers, and others who seek guidance in accessing regulatory and nonregulatory non-native plant lists in the state of Florida. This publication explains the origins of the lists, meaning of inclusion on a particular list, and ways to access each of the lists.
Hunting for natural enemies of the red imported fire ant is paying off for Agricultural Research Service (ARS) scientists. Their latest discovery — a new virus found in fire ants from Argentina — has the potential of becoming a biological control agent against the red imported fire ants infesting the U.S.
In parts of the South, there are stories about an invasive floating weed, which forms such a dense mass that it enables small animals to walk across water. This weed, called giant salvinia, is an exotic fern from South America that invades ponds, lakes, and other waterways in the United States. It damages aquatic ecosystems by outgrowing and replacing native plants that provide food and habitat for native animals and waterfowl.
Agricultural Research Service (ARS) scientists are testing a naturally occurring fungus (Myrothecium spp.) against giant salvinia to help control it. Initial tests have found that the fungus stops this problematic weed from growing and even can kill it.
