Grant funds are available for the control, prevention and research of state-listed aquatic invasive plants. Grants are available to local lake associations and municipalities for control and/or prevention of state-listed exotic aquatic plants, and to institutions of higher learning for in furthering research associated with exotic aquatic plant management, control, biology, ecology or prevention.

European Alien Species Information Network.

A newly developed index identifies areas of the Mediterranean Sea which are most affected by non-native, invasive alien species introduced through the Suez Canal, by aquaculture or through shipping. The top invaders appear to be algae, according to the JRC study. The Cumulative Impact of Invasive Alien species (CIMPAL) index calculation brings together datasets on IAS distribution with literature information on the impacts of IAS on biodiversity.

California Department of Food and Agriculture.

A portion of Los Angeles County has been placed under quarantine for the Tau fruit fly (Zeugodacus tau group) following the detection of more than 20 flies in the unincorporated area of Stevenson Ranch, near the city of Santa Clarita.

This the first Tau fruit fly quarantine ever in the Western Hemisphere. The fly is native to Asia and is a serious pest for agriculture and natural resources, with a very wide host range, including numerous fruits and vegetables as well as a select range of native plants in California.

For the last seven decades, Cornell University’s College of Agriculture and Life Sciences (CALS) has been leading the fight against nematodes—invasive, microscopic worms that can destroy seasons' worth of crops. However, researchers had been working in a facility that lacked the infrastructure to keep pace with their innovative work. On August 1, 2019, thanks to a $1.2 million grant from New York State and another $400,000 in federal funding, CALS cut the ribbon on the new Golden Nematode Quarantine Facility, located on the Cornell campus in Ithaca, NY. The facility is the only research program in North America with expertise in biology, resistance breeding and management of potato-cyst nematodes. At the lab, Cornell scientists work in tandem with the U.S. Department of Agriculture (USDA) Agriculture Research Service (ARS).

Maine Department of Inland Fisheries & Wildlife.

To reduce the spread of aquatic invasive species in Maine, a law was passed by the Maine Legislature (effective June 16, 2023) that requires boaters to take specific actions to encourage water to drain from their watercraft prior to entering a water body or leaving a launch site. Aquatic invasive species are any fish, wildlife, or plant species that spreads to a water body where they do not naturally occur. These species are often transferred to new locations on watercraft, watercraft trailers, and other equipment associated with water recreation, and they impact the health of our waters, fish, and wildlife.

Maryland Matters.

Maryland renamed the northern snakehead to the Chesapeake Channa in April 2024. The name change aims to increase public interest in eating the fish and control its population. The Maryland Department of Natural Resources will begin changing the name on January 1, 2025.

Florida Fish and Wildlife Conservation Commission.

Commissioners approved rule changes in Chapter 68-5, F.A.C., regarding nonnative species on February 21, 2019. The new rules will add high-risk nonnative animals to the Prohibited list and clarify rule language by defining key terms. The rules also include provisions for people currently in personal or commercial possession of these species. All rule changes will become effective on May 2, 2019. The 90-day grace period will begin on May 2, 2019 and end on July 31, 2019. Have questions? Contact us at NonnativeSpeciesRules@MyFWC.com, or see New Nonnative Species Rules for more information.

There is growing concern that changing climate conditions will amplify the negative impacts of non-native invasive species and facilitate their expansion. Despite the potential ecological and economic impacts of invasive species expansions in the Northwest, there has been no comprehensive synthesis on climate change effects on invasive species – until now. NW CASC-funded researchers Jennifer Gervais (Oregon Wildlife Institute), Clint Muhlfeld (U.S. Geological Survey) and colleagues conducted an extensive literature analysis to determine the current state of knowledge about climate change effects on non-native invasive species in the Northwest.

Australian Invasive Species Council.

Today's announcement by federal agriculture minister David Littleproud to establish an office of environmental biosecurity will better prepare Australia to prevent and respond to new harmful pest, weed and disease invasions. The decision was announced today as part of a $138 million boost in investment for national biosecurity, including $7.6 million over five years to establish the office, headed by an Environmental Biosecurity Protection Officer, within the Department of Agriculture and Water Resources.

A "New Pest Advisory" provides information on new pests and diseases that have become established in Hawaii. Individuals can help reduce the spread of these pests and diseases by being aware of their signs and symptoms and not moving them to other islands in the State.

Interactions between invasive species and climate change present new challenges for resource management. Prior to a new study by NE CASC fellow Evelyn Beaury and her collaborators, however, it was unclear what the common concerns, strategies, limitations, and research needs were for managing invasive species in a changing climate. In their nationwide survey of invasive species managers from government, non-profit, and private organizations, Beaury's team found that while the majority of managers are very concerned about the influence of climate change on invasive species management, the organizations they represent are typically far less engaged with this issue. This study illustrates that the complicating challenge of climate change may open a new avenue for elevating the efficiency and success of current invasive species management efforts if a collaborative approach is adopted in this area.
