Organizational Overview

Founded in 1938, the Tree Care Industry Association (TCIA) is a public and professional resource on trees and arboriculture. TCIA has more than 2,000 member companies who recognize stringent safety and performance standards and who are required to carry liability insurance.

TCIA has the nation’s only Accreditation program that helps consumers find tree care companies that have been inspected and accredited based on: adherence to ANSI A300 tree care management standards and ANSI Z133 safety standards; maintenance of trained, professional staff; and dedication to ethics and quality in business practices.

TCIA also provide safety and educational programs, guidelines for tree service operations, ANSI A300 tree pruning standards, and much more. TCIA’s Certified Treecare Safety Professionals (CTSP) program is the industry's first safety certification program, credentialing individual arborists for safety practices and knowledge. Each year, TCIA hosts TCI EXPO, the world’s largest tree care trade show and conference.

The ANSI A300 series of standards for tree care operations – tree, shrub and woody plant management – apply to professionals who provide for or supervise the management of trees, shrubs, and other woody landscape plants. Intended users include businesses, government agencies, property owners, property managers, and utilities.

These standards should be used to develop written specifications for work assignments. They are not intended to be used as specifications in and of themselves. Management objectives may differ considerably and therefore must be specifically defined by the user. Specifications are then written to meet the established objectives and must include measurable criteria.

The Approved Standards Committee (ASC) A300 was approved June 28, 1991, and meets regularly to help write new, and review and revise existing ANSI A300 Standards. The committee includes industry representatives with broad knowledge and technical expertise from various disciplines of the green industry as well as residential, commercial, municipal, governmental, and academic fields of arboriculture.

ANSI A300 standards are divided into multiple parts, each focusing on a specific aspect of woody plant management. The current ANSI A300 standards for tree care operations – tree, shrub and woody plant management are:

  • ANSI A300 (Part 1) - 2008 Pruning
  • ANSI A300 (Part 2) - 2011 Soil Management (includes Fertilization)
  • ANSI A300 (Part 3) - 2006 Supplemental Support Systems (includes Cabling, Bracing, and Guying, and Propping)
  • ANSI A300 (Part 4) - 2008 Lightning Protection Systems
  • ANSI A300 (Part 5) - 2012 Management of Trees and Shrubs During Site Planning, Site Development, and Construction
  • ANSI A300 (Part 6) - 2012 Transplanting (includes Planting)
  • ANSI A300 (Part 7) - 2006 Integrated Vegetation Management (IVM)
  • ANSI A300 (Part 9) - 2011 Tree Risk Assessment
  • ANSI A300 (Part 10) - 20xx Integrated Pest Management (IPM)
