Evaluation of structural integrity, root zone health, canopy condition, and disease or pest pressure before problems become emergencies.
Formal assessment of failure likelihood, targets, consequences, and recommended actions in a written report.
Diagnosis for Oregon tree threats including sudden oak death, Swiss needle cast, bark beetles, and root rot.
Practical care plans for heritage trees, mature oaks, landscape trees, and root zones near construction.
Tree protection zones, grading-plan review, and contractor specifications to reduce construction-related tree decline.
Professional documentation for disputes, property sales, insurance claims, permits, and formal opinions.
A clear visit, plain-language findings, and an action plan built around the right outcome for your property.
PN-10032A credentialed by the International Society of Arboriculture, with verified competency in tree biology, pruning standards, diagnosis, and risk evaluation.
TRAQ qualification is the gold standard for formal tree failure risk evaluation, including likelihood of failure, targets, consequences, and recommended action.
A tree trimmer removes branches to improve appearance or clear hazards. An ISA Certified Arborist is a trained diagnostician – they evaluate tree health, assess structural risk, diagnose disease, and develop care plans based on tree biology. Think of the difference as a barber versus a physician. Both work with the same subject, but the skill set, scope, and accountability are fundamentally different.
In many cases, yes. Cities like Portland, Lake Oswego, and Salem require a formal arborist assessment before issuing permits to remove or significantly modify certain protected trees. Our certified arborist can provide the documentation your city requires. Requirements vary by municipality, so we recommend contacting us to confirm what applies to your property.
Common warning signs include sudden or progressive leaning, large dead limbs, cracks or splits in the main trunk or major limbs, fungal growth at the base indicating root rot, or a history of storm damage. However, many structural defects are not visible from the ground – which is why a formal ISA Tree Risk Assessment is the most reliable way to evaluate risk.
Often, yes. Removal is not always the right answer. Structural cabling, targeted pruning, soil remediation, or disease treatment can extend the life of a valuable tree significantly. Our arborist will give you an honest assessment of whether a tree can be saved and what it would take – so you can make an informed decision.
Yes. Our ISA Certified Arborist serves both the Willamette Valley, including Albany, Salem, Corvallis, Lebanon, Eugene, and surrounding areas, and the Portland Metro, including Portland, Lake Oswego, Tigard, Tualatin, Oregon City, Wilsonville, Canby, and more.
A formal TRAQ assessment report documents the tree species, location, observed defects, likelihood of failure, size of the part likely to fail, potential targets, and an overall risk rating: low, moderate, high, or extreme. It includes recommended actions and a re-inspection interval. This document is recognized by insurance companies, municipalities, and courts.
