ISA Municipal Specialist study guide
ISA Municipal Specialist · Work through your exam, one topic at a time.
The ISA Municipal Specialist credential is a specialty certification for arborists and urban foresters whose work is shaped by public ownership: street trees, park trees, right-of-way plantings, and the political and budgetary machinery that surrounds them. It is aimed at people who already hold ISA Certified Arborist status and want to demonstrate competence in the municipal context specifically, where the technical work is entangled with ordinances, public money, elected officials, contractors, and residents who all feel entitled to an opinion about the trees in front of their houses. The ISA Municipal Specialist study guide has 8 sections and about 2,743 words.

366 words, about 2 min05Tree Maintenance, Pruning, and Risk Management
This domain covers pruning standards, maintenance scheduling, and the risk assessment process that drives municipal liability management.

332 words, about 2 min06Tree Protection During Construction and Development
