NPS policy requires that all parks use Integrated Pest Management (IPM) to address pest issues. A pest is any organism that is threatening or damaging cultural resources, natural resources or visitors and staff. IPM is a decision-making process that coordinates knowledge of pest biology, the environment, and available technology to prevent unacceptable levels of pest damage while reducing risks to people and the environment. The National Capital Region IPM Program provides coordination and technical assistance to the Region's parks. The Program Coordinator helps to prevent and control exotic insects, plants, diseases and other organisms that threaten natural and cultural resources or pose a health threat to visitors and staff.
