Invasive Species - What's New on NISIC's Site

Science conducted by the USGS and the White-nose Syndrome (WNS) Response Team. Our scientists are tracking the fungus as it spreads and characterizing the effects of WNS on hibernating bat populations in North America.

ITP, in collaboration with Pollinator Partnership, is pleased to release The BeeMD at idtools.org. The BeeMD will help beekeepers and others concerned with bees quickly identify honey bee health issues (including colony collapse disorder), through an interactive, visually rich, informative, and easy to use website. This release includes much of the content from the original website first published in 2016. On this new platform, the “visual key” has been completely restructured and streamlined, and the entire website redesigned and expanded, offering additional informational, visual, and supportive content.

The soybean cyst nematode, an invasive parasite that attacks soybean roots – causes over $1 billion of damage each year in the U.S. Harnessing beneficial fungi that target these nematodes could be a solution. Scientists with the Agricultural Research Service (ARS) are stepping up their efforts to control agricultural pests, without the use of chemical pesticides. One promising solution are fungi carried by the pests themselves in a symbiotic relationship.

Terrestrial invasive plants are expected to shift their ranges in response to changing climate. This tool provides lists of terrestrial invasive plants expected to expand their ranges into the chosen county or state with climate change by 2040-2060. Users can filter the list to species currently observed within a chosen geographic proximity to the focal county or state.

A web application displaying visual and statistical summaries of nationwide habitat suitability models for manager identified invasive plant species. INHABIT is a dataset containing the potential distribution of 259 invasive terrestrial plant species across the contiguous U.S.

This project is one among a set of coordinated projects funded (wholly or partially) by the Bipartisan Infrastructure Law through the US Department of the Interior to advance a nationally coordinated Early Detection and Rapid Response Framework.

Early detection is critical to the eradication and management of invasive species, and curious members of the public play a key role by sharing observations on platforms such as iNaturalist. Integrating these sightings from a bug-curious public into ongoing biosecurity surveillance is an increasingly valuable approach for invasive species management.

Feral swine (wild pigs, boars or feral hogs) are a destructive, invasive species that are prevalent in the U.S. and Canada. Federal, State, Provincial, local and territorial agencies are working together to manage the threat and damage caused by feral swine and to mitigate their impact. 

 The Coast Guard Office of Commercial Vessel Compliance was notified by the State of California on the detection and identification of golden mussel (Limnoperna Fortunie) in the Port of Stockton. To minimize the spread of the golden mussel it is recommended that operators continue to ensure that ballast water management systems are operational and used in accordance with the Operational Manual for that system.

Golden mussel (Limnoperna fortunei), an invasive, non-native freshwater bivalve, was recently discovered in the Port of Stockton by California Department of Water Resources staff while conducting routine operations. This discovery is the first known occurrence of golden mussels in North America. The species poses a significant immediate threat to the ecological health of the Delta and all waters of the state, water conveyance systems, infrastructure and water quality. Please report organisms observed in California suspected to be golden mussels to CDFW’s Invasive Species Program.

The widely cited “tens rule” in invasion ecology suggests that approximately 10% of established, non-native species will become invasive–or display negative impacts—when introduced to new environments. This study demonstrates that the tens rule is a poor estimate of invasion rates on a global scale. Instead, a ‘twenties rule’ is a better rule of thumb, meaning that roughly 20% of all established, non-native species eventually become invasive
