Local Tree Care Providers

The following companies have completed the City’s Local Tree Care Providers Workshop, have an active Portland business license, and do not have documented tree code violations within the past year. This list is for informational purposes only. The City makes no representation or warranty as to the quality of work performed by any company on this list. Any person seeking the services of an arborist is encouraged to consult with several companies and references to determine the arborist’s qualifications and suitability to perform the desired work.

Oregon State Licensing Information

Getting on the List

At least one Certified Arborist from your company must attend a Local Tree Care Providers Workshop and verify their attendance. Workshops are offered twice a year and will be advertised on this webpage. ISA CEU's may be provided.

Sign up for Tree Bark if you would like email notification of when the workshops are offered.

Removal from the List

As of October 20, 2015, a company on the Local Tree Care Provider’s List who performs documented tree work in violation of Title 11 will be removed from the list for one year. A Certified Arborist from the company must attend another Tree Care Providers Workshop before becoming eligible to be returned to the list. Companies in violation will be sent notification of the violation in writing before being removed from the list. Civil penalties and other violation fees and corrective actions may be imposed in addition to removal from the list. Violation fees can be found on the Urban Forestry fee schedule.

A company may also be removed from the list if they continue to submit incomplete, illegible, or incorrect applications after receiving verbal and/or written feedback from Urban Forestry staff. At the third documented instance in a 6-month period, the company shall be removed from the list for 6 months and until they have completed another Local Tree Care Providers Workshop. Offenders will be notified in writing before being removed from the list.

Every January 1st, or the first business day of the New Year, the list will be updated to remove those companies that have not attended a Local Tree Care Provider Workshop within one year of their last attended Workshop. This ensures that arborists have the most current information to provide to their customers.
