Commercial Arboricultural Practices in North America

Abstract

Arboriculture in North America developed con- currently along academic and commercial lines at the end of the nineteenth century. Today this is an industry of thousands of small businesses (two to five employees) servicing residential, commercial, industrial, governmental and utility customers. Only four commercial arboricultural firms do business on a national scale: Asplundh Tree Expert Company, Bartlett Tree Expert Com- pany, The Davey Tree Expert Company and Southeast Public Service Corporation
