In Maryland, persons engaged in the work of the treatment and care of trees for compensation must be licensed by the Department of Natural Resources. The Department of Natural Resources—Forest Service, the Mid- Atlantic Chapter of the International Society of Arboriculture, the Maryland Arborist Association, and the Maryland Community Forest Council cosponsored a survey of Licensed Tree Experts (LTEs). The survey's purposes were to estimate the total number of jobs and gross dollar revenue that the arboricultural industry provides to the state of Maryland; to identify the tree care industry as a constituency in the business community; to identify training resources and trade affiliations most used by LTEs; to identify business type, geographic concentration, and client type; and to provide input into agency regulations affecting the industry. It is estimated that the tree care industry in Maryland employs 2,841 individuals and generates more than $134.5 million in annual gross revenue.
