The result is not an ISA Tree Risk Assessment Qualification (TRAQ) rating, professional tree risk assessment, engineering opinion, prediction of failure, or guarantee that a tree is safe or unsafe. If a tree or branch appears to be actively failing, has fallen onto energized utility lines, or presents an immediate threat to people, avoid the area and contact the appropriate emergency or utility provider.
