Invasive species are one of the leading causes of degraded ecological condition and ecosystem services, and climate change has the potential to interact with this stressor through multiple mechanisms. OW and OPPTS are concerned with aquatic invasive species (AIS) in multiple arenas, including ballast water and NPDES permits, TMDLs and impaired waters, economic consequences, and pesticide usage for control. AIS are also used as biological indicators to measure ecosystem condition.

This draft report assesses the state of the science of climate change effects on AIS and examines state level AIS management activities. Part of the assessment focuses on AIS management plans to determine their capacity to incorporate information on changing environmental conditions generally, and climate change specifically. The report concludes that further scientific research and data collection are needed in order to equip managers with the tools and information necessary to conduct effective AIS management in the context of climatic change.The report is intended for managers and scientists working with AIS to provide them with information on the potential effects of climate change on AIS, strategies for adapting their management to accomodate these environmental changes, and highlight further research needs and gaps.


Jun 2006EPA hosted a workshop, Assessing Gaps and Needs for Invasive Species Management in a Changing Climate, on June 6, 2006 in Washington, DC.
Oct 2006EPA hosted a workshop, New Considerations for Aquatic Invasive Species in a Changing Climate: An Update on Papers for a Special Section in Conservation Biology, on October 2, 2006 in Washington, DC.
May 2007EPA conducts an internal review of the draft report for comments.

Next Steps

    There will be a 30-day public comment period beginning Aug. 2007
    External letter review projected Sept. 2007
    The final report will be published after addressing public and external review comments.
