What is a Certified Arborist?

According to the ISA, Certified Arborists must be:

“…trained and knowledgeable in all aspects of arboriculture. ISA Certified Arborists® have met all requirements to be eligible for the exam, which includes three or more years of full-time, eligible, practical work experience in arboriculture and/or a degree in the field of arboriculture, horticulture, landscape architecture, or forestry from a regionally accredited educational institute.”

Within this realm, we also have many subspecialties, including municipal, utility, and aerial lift. We pass lengthy exams, attend continuing education to keep our skills current, and prepare on an ongoing basis to bring you the science and research to provide the best care for your trees.

When are Reports Required?

The City of Portland and many surrounding communities have ordinances regulating the removal of trees, even on private property. Within Portland, in general, any tree with a diameter at the base over twelve inches and subject to other land size and use conditions cannot be cut without a special permit. Permits are based on arborist reports about the condition and safety issues of the tree.

Additional guidelines apply to certain tree species. Codes also mandate the density of trees remaining on a site, preservation requirements, and distances from existing or planned structures. Hazardous trees may require an arborist report under regulated situations.

We have over 300 Heritage Trees within the Portland city limits. Heritage designation is based on age and size, special historical or variety status, and other factors. Any work on these trees requires neighborhood notification, special care and condition reports, and a Certified Arborist’s inspection.

Building codes throughout our tri county area require tree inspection, planning and review by a Certified Arborist for commercial and residential construction projects. In these cases, we seek to protect surrounding natural and woodland areas not in the construction zone. We also review tree removal plans and intended tree replacement after construction is completed. The point is to keep the community green and protect wildland habitat, both of which contribute to the singular environment and lifestyle in our region.

Call PTS Before You Cut

Laws differ based on jurisdiction, project type, issue with the tree, and its species. That is why calling us at Portland Tree Service should be an important part of your own planning process. Our familiarity with the codes and regulations throughout our area means you can avoid costly legal surprises.
