Overview

The Regional Integrated Pest Management (IPM) Coordinator assists parks with management of pests using effective low-risk methods that protect resources, visitors, and staff. Pests include insects, plants, diseases and other organisms that threaten natural and cultural resources or pose a threat to human health. Methods include manual, mechanical, cultural, biological and chemical applications. All pesticides used on national park lands must be approved prior to use. The regional coordinator reviews and approves pesticides, biological control agents and genetically modified organisms proposed by park IPM coordinators. Pesticide usage is reported and tracked on an annual basis.
