As the fifth mega diverse country, and with invasive species identified as the third cause of biodiversity loss, Mexico has been working more and more towards addressing this relatively new topic.
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 […]
Natural resource managers throughout North America have identified feral swine as a significant challenge. This invasive species has emerged as a major environmental and economic concern as populations have exploded. […]
American bullfrogs (Lithobates catesbeianus) are not native to western North America and threaten dozens of Species of Greatest Conservation Need and many federally Threatened or Endangered species. Control or eradication […]

Abstract: NAISMA and our partners steward and implement international prevention programs, including PlayCleanGo®: Stop Invasive Species In Your Tracks® and Certified Weed Free Products (WFP). These well-established programs are aimed at stopping the spread of invasive species through specific human-assisted pathways. NAISMA was awarded a prevention grant from the US Fish and Wildlife Service, funded through […]
Managing invasive species is a costly, time and labor intensive process necessary for the restoration of natural ecosystems and the benefits they provide to the human communities surrounding them. While some species require technical expertise to effectively control, others can be managed through mechanical means by stewards of a diversity of backgrounds. People-powered restoration benefits […]
Introduced plant pathogens threaten North American forests. Some arrived in the distant past: chestnut blight, white pine blister rust, beech bark disease, Dutch elm disease, butternut canker. Damaging introductions continue through the late 20th Century (sudden oak death, laurel wilt) and recent decades (ohia rust, Fusarium blight, rapid ohia death, beech leaf disease). Introduction of […]
Biocontrol, the practice of using one species (biocontrol agents) to control another (target pest) is an important management tool. Conservation, augmentative, and classical/importation biocontrol have all been successfully used to reduce target pest species in agriculture and natural systems. Climate change may influence both well-established and new biocontrol relationships, yet the effects of climate change […]
