InvaCost is the most up-to-date, comprehensive, standardized and robust data compilation and description of economic cost estimates associated with invasive species worldwide. InvaCost has been constructed to provide a contemporary and freely available repository of monetary impacts that can be relevant for both research and evidence-based policy making.

Invader Detectives has been conceptualized as a national program to facilitate the detection of invasive species in urban environments. The majority of invasive species enter the country through the large commercial sea ports and airports located in our Nation’s cities. If we can rapidly detect and respond to potentially harmful non-native species at or near our borders, we can prevent them from spreading to natural areas and agricultural landscapes. Ultimately, this Contractor’s Report is intended to serve as the conceptual framework for developing and implementing Invader Detectives on a national scale through a chapter-based (regional) model. It is a living document and should not be regarded as final guidance. We welcome your input at invasive_species@ios.doi.gov.

"How climate changes will impact invasive species could vary depending on the region, the species affected, and the particular impacts being felt, but most invasives do well in a changing climate. We are already seeing some influences of climate change in Pennsylvania."

The Invasion Science Research Institute aims to synergize the significant research and training capacity currently distributed across multiple disciplinary-based Departments and Colleges at the University of Florida to transform understanding and management of invasive species.

 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.

Multiple federal, state and local agencies have been notified of an invasive algae species discovered in Newport Bay, California in March 2021. The algae, which is native to Florida and other subtropical and tropical locales, is scientifically known as Caulerpa prolifera. It can grow quickly, choking out native seaweeds and potentially harming marine life through lost habitat.

A similar species of invasive algae, Caulerpa taxifolia, was identified in California in 2000 and was successfully eradicated through a comprehensive joint local, state and federal effort in 2006. Due to the similarity between these two species, scientists believe this algae species may pose a serious threat to our local coastal ecosystems.

However, it is imperative that the public avoid contact with the plant due to its extreme ease of recolonizing from just tiny fragments. If you believe you have seen this invasive algae, please complete a sighting report. Please do not collect a specimen, as this may lead to further spread.

These plants are known to be invasive or potentially invasive in Connecticut and are on Connecticut's list of Invasive and Potentially Invasive Plants. They are known to be present only in relatively low numbers at limited locations in Connecticut. These species should be considered for control and eradication efforts in the state when resources are available. If you find these species: Report your findings immediately to the CT Invasive Plant Coordinator at reportinvasives@uconn.edu.
