Many arborists learn tree work practices without fully understanding the biological and physiological principles behind them. However, outcomes for the health and longevity of trees are greatly improved when an arborist understands the science behind the care of tree root systems and crowns. In Applied Tree Biology, Drs. Hirons and Thomas draw upon their decades of experience in the laboratory, classroom, and the field - as well as the expertise of distinguished contributors to this volume - to provide those responsible for tree care with the scientific information that informs best practices for planting, pruning, soil decompaction, irrigation, and much more. Takes a multidisciplinary approach, integrating knowledge from plant biology, physiology, arboriculture, ecology, and moreProvides a systematic presentation of fundamental tree biology and the scientific principles informing high quality tree carePresents accessible scientific information and best practices that help promote the health and longevity of treesReflects the authors' decades of experience as tree biology researchers and educators, as well as their years of professional experience across the globeApplied Tree Biology is an indispensable source of practical, succinct information on tree biology, physiology, and ecology for professionals and interested amateurs involved with the care of trees. Arborists, foresters, and horticulturists at all stages of their careers will find this text particularly useful.
