The spread of invasive species remains one of the nation’s and the Refuge System’s most pervasive threats to ecological integrity and resilience. Climate change is likely to exacerbate the threat. Currently, the Refuge System is focused on controlling large, well-established infestations rather than pursuing early detection and complete eradication of smaller incipient populations. More emphasis on prevention and early detection and rapid response may be a more efficient and effective strategy in the long term.

In implementing Fulfilling the Promise, the Refuge System developed a strategic plan for invasive species. From that came development of invasive species strike teams to provide rapid response capability in certain areas. They have proved highly effective. A cooperative effort with the National Wildlife Refuge Association developed a volunteer and invasive species program, in which volunteers undertake early detection and mapping. The Service has worked with programs to eradicate rats and restore bird nesting colonies on a number of islands.

Recommendation: Update the Refuge System’s invasive species strategy to include implications of climate change and determine clear priorities and performance measures to guide future work.

Recommendation: To leverage limited federal funding resources available to wildlife refuges and the U.S. Fish and Wildlife Service, mobilize 10,000 volunteers over the next 10 years to map, inventory and eradicate invasive species on wildlife refuges.
