Parks Integrated Pest Management

Why Integrated Pest Management?

To carefully and effectively manage noxious and invasive species of plants within the community's Parks system, the Parks Maintenance Division utilizes the best practices of Integrated Pest Management.

What is Integrated Pest Management?

Integrated Pest Management (IPM) is an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices. IPM programs use current, comprehensive information on the life cycles of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment. The Parks Maintenance Division utilizes this best practice to thoughtfully control and eradicate noxious/invasive plant species that would otherwise out-compete native varieties.

Locations Utilizing Integrated Pest Management?

The Parks Maintenance Division is responsible for maintaining many Park sites throughout 627 acres of City of Lake Oswego Parks Property. The maintenance is done by Parks Staff and Contractors.



Is IPM Just About Pesticides?

No, IPM is not just about pesticide use, it is a strategy guide to manage public spaces utilizing a wide range of "tools" from mulching to application of pesticides. IPM is a “toolbox” and a living document. It provides a comprehensive list of effective methods to manage pests and to minimize the damage they have on public spaces. Pesticides are a very small part of the overall management toolbox. The most current IPM Document is available for the public to read.  

Staff Certification

All Park Maintenance Staff that use pesticides are required to be Licensed Certified Applicators. Any contractors that work for the department must also be Licensed Certified Applicators. To be certified, each applicator must go through a comprehensive training program and receive continuing education through the Oregon Department of Agriculture.

Updating Practices

The Parks Maintenance Division annually reviews and updates the IPM document establishing best management practices. The goal is to utilize minimal environmental inputs to achieve maximum effectiveness. Each year, staff strive to find better avenues that environmentally and economically manage pests and continue to use safe practices.

Application of Pesticides

When application of pesticides occurs, the Certified Applicators are trained to properly measure and mix the smallest but most effective amounts of pesticides for the task. Applications of pesticides are applied selectively utilizing spot treatment.

Natural Character Park Invasive Removal

Within the past three years, Council provided the Parks Maintenance Division with funding to begin restoration of our Natural Character Park spaces which includes eradicating invasive species (Ivy, Clematis, Holly, and other species).
