What This Program Does
The new paradigm shifts the decision of which branches to prune from the production arborist to an informed prescriber. It establishes a protocol resulting in consistency between the arborist preparing the prescription and the production arborist. This credential teaches you how to prescribe and perform pruning in accordance with industry standards and ISA’s BMP supported by the latest research and experience.
Why Should I Get This Qualification?
- Improves professionalism for new and seasoned arborists.
- Establishes a standardized, accountable, objectives-based pruning process.
- Teaches an approach that increases life expectancy and clearance and reduces likelihood of failure.
- Improves your ability to explain to tree owners, contractors, and crew why and how to prune.
