Background:

Biological invasions by nonnative species are escalating in frequency and impact.
Damages to ecosystems, economies, and human well-being are mounting due to invasive species.
Current U.S. policies require updating with scientific knowledge to address escalating threats.

Purpose of the Study:

To evaluate U.S. national policies and practices regarding biological invasions.
To recommend science-based strategies for improved invasive species management.
To advocate for federal leadership and investment in combating invasive species.

Main Methods:

Evaluation of current U.S. national policies and practices on biological invasions.
Synthesis of current scientific knowledge on invasive species.

Development of recommendations for federal government action.

Main Results:

Invasions by harmful nonnative species are increasing in number and area.
Damages from invasive species are accumulating across ecological, economic, and social sectors.
Current strategies are insufficient without improved scientific approaches and increased investment.

Conclusions:

Federal leadership is essential for effective prevention, detection, response, and control of invasive species.
Six key actions are recommended for the federal government to enhance invasive species management.
Investing in science-based strategies and technologies will yield significant returns by reducing damages from invasive species.
