Integrated Pest Management Program

The Integrated Pest Management Program (IPM) is a science-based decision-making system used to design and control pest populations in order to limit their impacts as well as risks to people and the environment.


Santa Clara Valley and its surrounding hillsides are threatened by pest species that harm our natural lands. Many of these pests are exotic species that are not native to this region and were introduced by people with unintended consequences. Most of these exotic plants and animals affect native species by changing the natural ecosystem or creating fire hazards. Controlling these pest species is one of the ways in which the Authority stewards its lands.
The Authority will use the Integrated Pest Management (IPM) framework to guide how we manage pests, so we can limit the risks and impacts to our preserve visitors, staff, and the lands and facilities we manage. To accomplish this, the Authority developed a draft IPM policy and guidance manual to guide and inform pest management strategies that are efficient, cost-effective, protect human health and safety, and protect natural resources.


The Authority is releasing the Integrated Pest Management Draft Programmatic Environmental Impact Report. The Authority is seeking feedback from the public and partners on the draft policy, guidelines, and environmental review. A public hearing is scheduled for April 20, 2021 at 6:00 p.m. to receive public comment. Register here.

Interested parties may provide the Authority with written and/or email comments on the Draft PEIR until May 17, 2021 at 5:00 pm.

The six components of an ipm program Are:

  1. Correctly identifying the species
  2. Monitoring and assessing where the pests are located and how abundant they are
  3. Setting thresholds for targeted control
  4. Assessing site conditions to identify appropriate control treatments
  5. Using the least harmful suite of control methods
  6. Preventing pest problems by detecting new occurences early and treating them quickly
