The NPS has a program to control and eradicate invasive species in lands and waters within agency boundaries. One of the NPS’s largest efforts is through Exotic Plant Management Teams, which are field-based teams of NPS employees and student interns that travel to various parks and apply herbicides and mechanical treatment to rid areas of invasive terrestrial plants. The NPS cooperates with partners to respond to newly detected invasive species. In some instances, depending on funding and authority, local park staff and partners will actively respond to newly detected invasive species and work to restore impacted areas to natural communities. Public education and outreach varies depending on local park units. The agency also maintains a number of websites related to invasive species, particularly terrestrial plants, and works with partners to compile, manage, and distribute data on specific occurrences of invasive species.
