Adopted in 1945, the Maryland Tree Expert Law addresses tree care work done for compensation on private or public property in Maryland. The purpose of the law is to provide a layer of consumer protection by licensing qualified and insured tree care companies and individuals. Anyone seeking to practice or advertise tree care services in the State of Maryland must obtain a license from the Maryland Department of Natural Resources.
Who must have a license?
All tree care professionals practicing in Maryland must obtain a license. Without a license, they may not practice or advertise tree care services in the state. To obtain a license, the applicant must possess adequate and related college education plus one year of experience under a LTE or have five years experience under a Licensed Tree Expert (LTE), then have passed an exam and carry adequate amounts of liability and property damage insurance.
