The following information was sent this year to all MD Licensed Tree Experts with their license renewal paperwork. Effective October 17, 2011, the Tree Expert regulations have been revised to increase the license to a two year time frame staggering this change and increasing the fee to reflect the new two year license.
For example, ending in December 2011:
a) the odd numbered licenses (those ending in the numbers 1,3,5,7,9) will renew their licenses for a two (2) year period, 2012 & 2013. The fee has increased to $25.
b) the even numbered licenses (those ending in 0,2,4,6,8) will renew their license for a one (1) year period, 2012. The fee will remain at $10.
So the next year, ending in December 2012:
a) the odd numbered licenses will not need to renew their licenses.
b) the even numbered licenses (those ending in 0,2,4,6,8) will renew their license for a two (2) year period, 2013 & 2014. The fee will be $25.
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 three years experience under a Licensed Tree Expert (LTE), then have passed an exam and carry adequate amounts of liability and property damage insurance. The license must be renewed annually every January.
