Arboriculture -- the emphasis on keeping trees alive and healthy -- has emerged only recently as a profession; however, the practices in use today are the culmination of decades of development. The first book of its kind, Aboriculture: History and Development in North America chronicles a century of this qlove of treesq view as it has developed into a viable profession. Beginning with a discussion of the origins of planting, transplanting, and pruning, Richard Campana provides a breadth and depth of understanding of how arboriculture has become an important force in modern ecology. Specific topics discussed include: the introduction of woody plants to North America; botanical gardens and arboreta; gypsy moths; Dutch elm disease; the Davey, Bartlett, and Asplundh tree experts; herbicides, insecticides and fungicides; pruning; fertilization; wound treatment; and cabling, bracing, and lightning protection.
