“State forestry agencies support local programs to inventory public
trees in a wide range of settings – from street trees to trails to
wooded parks. Managing risk for those public trees is ‘Job 1’ for city
tree managers and the new ANSI standard for tree risk assessment helps
state and local governments define appropriate methods and work plans
for getting this work done.”
Pete Smith, Partnership Coordinator with
the Texas Forest Service-Urban Forestry Program
The A300 Part 9 Tree Risk Assessment standard takes precedence over any previous tree care management standards and guidelines. The standard addresses:
