Best Practices

ISA has developed a series of Best Management Practices (BMPs) for the purpose of interpreting tree care standards and providing guidelines of practice for arborists, tree workers, and the people who employ their services. Protection and restoration of soil quality is an important task and should be a goal for arborists, tree owners, and managers. This BMP recommends practices for assessing, modifying, and conserving soils that support trees and shrubs in the urban environment. (©2021, softcover, 70 pp.) 1 CEU (A, U, T, M, L, Bp, Bs)

ISA has developed a series of Best Management Practices (BMPs) for the purpose of interpreting tree care standards and providing guidelines of practice for arborists, tree workers, and the people who employ their services. The purpose of this BMP is to guide utility personnel, utility vegetation managers, utility tree risk assessors, and line clearance contractors in assessing tree-related risk to overhead electric utility infrastructure by tree failure as accurately and consistently as possible, and to support decisions related to risk mitigation practices that achieve utility objectives. It also serves as a companion publication to the ANSI A300 Part 9: Tree, Shrub, and Other Woody Plant Management—Standard Practices (Tree Risk Assessment a. Tree Failure) (©2020, softcover, 95 pp., glossary, appendices). (A, U, T, L, Bp, Bm)

This month’s Best Practices podcast focuses on an often forgotten area of tree inspection; the root crown. A simple root crown excavation can reveal a wealth of potential problems, and when done and mulched, provide a needed safety buffer zone around the tree. The available quiz covers this episode, plus the previous episodes of Personal Protective Equipment (PPE), Setting up a TPZ, Soil Texture, Measuring DBH, and Chainsaw Safety Features.
