NISAW Webinar: The Water Resource Development Act Provisions for Invasive Species Management

February 22 @ 1:00 pm - 2:30 pm


Congress utilizes legislation titled the Water Resources Development Act (WRDA) to authorize and guide the U.S. Army Corps of Engineers (USACE). Since WRDA 1986, Congress often has considered a WRDA biennially. The most recent WRDA was passed in 2022 as part of an omnibus appropriations and authorizations act (PL 117-263). The WRDA not only authorizes research and projects, but also provides policy direction to the USACE.

The WRDA has several important provisions for invasive species management including the aquatic plant control program, watercraft inspection and decontamination, zebra and quagga monitoring, and rapid response. The WRDA has successfully been used to provide much needed resources for research, prevention, control, and management of invasive species across the country.
