Denying Entry: Opportunities to Build Capacity to Prevent the Introduction of Invasive Species and Improve Biosecurity at US Ports (2007)

International Union for Conservation of Nature.

The aim of this report was to identify the resources, strategies, and policies necessary to create, maintain, and make accessible one or more commodity/invasive species databases that EPA and other relevant agencies can apply to trade policy decision-making in a timely and scientifically-based manner.

Hitchhiking Seeds Pose Substantial Risk of Nonnative Plant Invasions (Sep 29, 2020)

USDA. FS. Southern Research Station. CompassLive.

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 Federal Noxious Weed List. 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.

Marine Debris as a Potential Pathway for Invasive Species (2017)

DOC. NOAA. Marine Debris Program.

There is mounting concern over the increase in debris in our ocean and the potential for that debris to assist in the spread of non-native species. While the pathways associated with global shipping draw the greatest amount of attention regarding marine invasives, the purpose of this paper is to consider the potential role that marine debris may play in introducing non-native species that may become invasive. This report reviews the scientific literature that exists on the subject and identifies areas where more research is needed.

New Zealand’s Craft Risk Management Standard for Vessel Biofouling: A Blue-Print for Marine Pathway Management (Jul 29, 2020)

New Zealand Ministry for Primary Industries. Biosecurity New Zealand; National Institute of Water and Atmospheric Research.

New Zealand is the first country to implement nationwide regulations to manage risks associated with biofouling on international vessels. The development of this regulation and its implementation can serve as a blue-print for other jurisdictions that are interested in preventing the spread on non-indigenous marine species.

Report Lifts Lid on Australia's International Bug Superhighway (Apr 15, 2020)

Australian Invasive Species Council.

A new report has identified an international 'bug superhighway' capable of carrying a large variety of environmentally destructive overseas insects into Australia. The study, led by Monash University, rated the environmental harm being caused by 100 of the worst overseas insect species and recommends a string of actions to keep them out of Australia. The most dominant group of invasive insects by far are the hymenopteran insects – ants, bees and wasps – making them the world's most environmentally harmful invasive insect species.

"Our report found that environmentally harmful bugs, beetles, ants and moths are most likely to hitch a ride into Australia along an international bug superhighway made up of imported plants, nursery material and the timber trade," said report author Professor Melodie McGeoch from Monash University. The report identifies the international trade in cut flowers and foliage as a high-risk pathway for more than 70 of the species studied. Invasive Species Council CEO Andrew Cox said this is the first time Australian and international scientists have comprehensively analysed which invasive insects overseas are doing the most environmental harm and could therefore threaten Australia's natural environment if they breach the nation's borders.

USDA Declares August Tree Check Month (Jul 23, 2020)

USDA. Animal and Plant Health Inspection Service.

Urges Public to Look For Invasive Asian Longhorned Beetle and Not Move Firewood

August is the peak time of year to spot the Asian longhorned beetle (ALB) as adults emerge from trees. That’s why the U.S. Department of Agriculture (USDA) is declaring August as ‘Tree Check Month.’ Checking trees for the beetle and the damage it causes is one way residents can protect their own trees and help USDA’s efforts to eliminate this beetle from the United States.
