  • This edition from the Visual Identification Series by Urban Forestry LLC was created to simplify the pruning process for small and young trees. Designed for use in the field, an easy to learn and recall acronym-based methodology directs you where to start, what branches to prune, and when you are finished. It is intended for a wide range of users, from tree workers who may have little or no experience pruning trees, to professional arborists and landscapers. By Andrew G. Pleninger and Christopher J. Luley
  • This well-illustrated book with numerous color photographs will help tree professionals build on their knowledge and application of current industry standards, including the American National Standards Institute's ANSI A300(Part 1): Tree Pruning and ISA's Best Management Practices: Tree Pruning. It describes an approach to pruning that reduces risk by promoting a sound tree structure that resists failure, provides clearance, and improves aesthetics.

  • Documenting Evidence: Practical Guidance for Arborists, by Julian A. Dunster, Foreword by Nelda MathenyIf your work requires that you collect information (evidence) and analyze it to form opinions and prepare reports or testify, this book is for you. The framework and principles described will help professionals performing a variety of services including testifying as an expert, diagnosing problems, resolving disputes, completing accident reports, and even assessing trees. Key ideas are clearly illustrated, often in a case study type of format, with illustrative photographs and graphics.(©2014, softcover, spiralbound, 54 pp.) By Julian A. Dunster

    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.
