Research & Publications




Managers and practitioners should be aware of all relevant standards and Best Management Practices (BMPs) related to utility arboriculture and utility vegetation management. The UAA encourages employers to make these BMPs available to all field personnel.

Tree Worker Safety ANSI Z133: The 2017 Z133 Safety Standard was developed for the arboriculture industry under the procedures of the American National Standards Institute. The 2017 revision provides the most current criteria in the United States for arborists and other workers engaged in arboricultural operations:

  • General safety
  • Electrical hazard
  • Use of vehicles and mobile equipment
  • Portable power hand tools
  • Hand tools and ladders
  • Climbing
  • Work procedures

This publication provides an essential guide for federal, state, and municipal authorities in drafting regulations.

ANSI A300 Standards are the generally accepted industry standards for tree care practices.
They are voluntary industry consensus standards developed by TCIA and written by a committee called the Accredited Standards Committee (ASC) A300, whose mission is to develop consensus performance standards based on current research and sound practice for writing specifications to manage trees, shrubs, and other woody plants.

    Industry Best Management Practices


    Industry leaders gather each year at the System Utility Vegetation Management Summit and discuss best practices. The following white papers provide insight into various issues and current thinking about state-of-the-art utility vegetation management. Please note that these papers have not undergone the type of rigorous review that would qualify them as “Best Management Practices” but reflect the discussion among these industry leaders.
