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 is written for professionals who manage a large number of trees that are considered primarily as individuals rather than as groups, in locations such as municipalities, university campuses, cemeteries, military bases, corporate grounds, arboreta, homeowners associations, and private grounds. It strives to serve as a guide for making informed choices that will match inventory goals with needs and resources. Topics in this BMP include:
- Inventory Goals and Objectives
- Inventory Benefits and Costs
- Inventory Types
- Developing Work Specifications
- Maintaining Inventory Quality

Written specifically for tree climbers, this publication can be used as a basic text for the tree climber as well as a study guide for the ISA Certified Tree Worker Program. This guide contains more than 200 color illustrations. Each chapter includes a list of important terms and concludes with a workbook section.
This book was written from the perspective of what the climber needs to know in order to climb and do aerial tree work safely. Chapters include Tree Health and Sciences, Safety, Ropes and Knots, Climbing, Pruning, Rigging, Removal and Cabling. Appendices with answers to the workbook questions, a glossary, and additional references also are included.

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.
