    A must-have resource for researchers and practicing arborists alike. This book offers an in-depth look at a tree's physiologic response to wounding, helping arborists to understand wound reactions of bark, cambium, and wood, as well as the factors that influence the tree's response. To help readers understand the complex responses more easily, the authors further developed Alex Shigo's 1977 CODIT Model into the broader CODIT Principle, which describes the reactions from injury to rot encapsulation as a series of phases. The CODIT Principle clarifies why some wounds have problematic consequences for the tree while others do not.

  • 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. This BMP describes tree preservation practices that help to protect selected trees throughout the construction process so that they will continue to provide benefits for decades after site disturbance. Topics in this BMP include:
    • Planning Phase
    • Design Phase
    • Pre-Construction Phase
    • Construction Phase
    • Post-Construction Phase
