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 each 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.

2023 Local Tree Care Provider Workshops

Only one (1) workshop will be offered in 2023. 

This free workshop is for tree care professionals who work in Portland. Learn about different kinds of tree permits and how to submit applications. Urban Forestry staff will be online to answer your questions. ISA CEUs may be available. Companies must attend one of the two workshops offered to remain on the list.

Friday, November 3, 2023. 8:30 am - 11:30 am 

Removal from the List

As of October 20, 2015, a company on the Local Tree Care Providers 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 1, 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.
