The American National Standards Institute (ANSI) has approved major revisions to industrywide standards for planting and transplanting trees. While the ANSI standard (ANSI A300 Part 6) initially only covered the transplanting of trees, it now has been expanded to include initial planting of trees as well. The revised standards are based on a consensus among industry experts about a variety of best practices. The areas covered include plant and site inspection, tools and equipment, digging, installation of plants, support systems and best care practices after the tree is planted. The revised standard is available in a hard copy document from the International Society of Arboriculture. To purchase it from the ISA store, click here.
