ISA Certification
ISA Oak Wilt Qualified (OWQ)
What It Means
ISA OWQ certification qualifies an arborist to identify and manage oak wilt disease. This credential ensures proper diagnosis of this devastating pathogen and implementation of prevention and containment strategies critical to oak tree survival.
Why It Matters
Oak wilt is one of the most destructive oak diseases in North America. We often hear from clients about trees incorrectly labeled as having oak wilt by well-intentioned others—misdiagnosis can be costly both ways. OWQ certification means we can accurately identify true infection, implement proper containment protocols, and protect your oak trees through science-based management. Early and accurate detection saves trees.
