Midpen’s Integrated Pest Management (IPM) program guides how we care for our preserves by managing plant and animal pests in a way that protects people, wildlife, and the environment. Our work supports healthy ecosystems, safe public access, and reduced fire risk. This work is guided by Midpen’s IPM Guidance Manual, which outlines our science-based, District-wide approach.
For every project, Midpen biologists evaluate site conditions and select methods that are effective while minimizing impacts. We prioritize non-chemical methods whenever possible, including hand removal, cutting, mowing, trapping, and sanitation practices that prevent the spread of pests. When needed, additional tools are used as part of the IPM toolkit, applied carefully and only when they are the right fit. Our approach is adaptive, with ongoing monitoring and adjustments to support long-term stewardship.

Current Projects
Rodenticides
At-home use of rodenticides (pesticides that target rodents) pose a significant threat to wildlife in our preserves and are especially dangerous to predators and scavengers, such as owls, coyotes, mountain lions and bobcats.
Midpen continues to work with other agencies and organizations to limit rodenticides and promote alternative pest control methods. Learn more about our efforts to reduce use of rodenticides in our community.
Sudden Oak Death
Sudden Oak Death is killing oak and tanoak trees throughout coastal California and Oregon. Caused by the water mold Phytophthora ramorum, the pathogen spreads with moist winds and by moving infected vegetation and soil, including material accidentally carried by shoes and tires.
To prevent the unintentional spread of Sudden Oak Death, field and construction crews follow “clean practices” when working in infected areas to limit its spread into new areas. You can do your part by staying on trails, cleaning your shoes, pet’s paws and tires both before and after your visit to any preserve. Read more to learn about SOD on Midpen lands.
