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. Chapters in this BMP include: Inventory Goals and Objectives. Inventory Benefits and Costs. Inventory Types. Developing Work Specifications. Maintaining Inventory Quality.
