Maryland’s Licensed Tree Expert law, codified under Natural Resources Article Section 5-418, stands among the oldest consumer protection statutes governing commercial tree work in the United States. Originally adopted in 1945 and later amended to expand the definition of “tree expert” to include tree removal, the law requires anyone performing tree care or removal for compensation on private or public property to hold a license issued by the Maryland Department of Natural Resources Forest Service. Applicants must complete at least two years of approved college coursework in forestry, arboriculture, horticulture, or applied agricultural sciences and accumulate a minimum of one year of supervised experience under an existing Licensed Tree Expert, or alternatively demonstrate three consecutive years of practice under a Licensed Tree Expert without the college requirement. All candidates must then pass a DNR-administered examination held approximately ten times per year at the Tawes State Office Building in Annapolis. The license costs $30, remains valid for two calendar years, and requires eight continuing education units per renewal cycle. Licensed Tree Experts must carry liability and property damage insurance at amounts specified by the Department, and the law mandates written contracts with clients before work begins.
The regulatory framework extends beyond the private-sector license. Maryland’s Roadside Tree Law, passed in 1914, requires a separate Roadside Tree Care Permit from DNR before any tree located within a public road right-of-way can be planted, pruned, treated with pesticides, or removed. Local jurisdictions add further layers: Baltimore City issues tree work permits through its Department of Recreation and Parks for street trees, while Montgomery County and Prince George’s County each enforce tree canopy protection ordinances that may require replacement plantings or mitigation fees when significant trees are removed on private property.
Geographically, the state’s compact 12,400 square miles stretch from the Appalachian ridges of Garrett and Allegany counties in the west to the flat Coastal Plain of the Eastern Shore, producing a diverse tree population that shifts dramatically by region. Western Maryland’s hardwood forests are dominated by northern red oak, sugar maple, and tulip poplar, while the Piedmont Plateau running through Baltimore, Howard, and Carroll counties supports mixed stands of white oak, hickory, and sweetgum. Closer to the Chesapeake Bay, loblolly pine and southern red oak become prominent, and tidal areas harbor bald cypress in some lowland zones. This variety means that tree removal contractors working across multiple Maryland counties encounter a broad spectrum of species, each presenting distinct challenges in terms of wood density, root architecture, and proximity to structures.
Maryland’s climate falls within the southern temperate zone, allowing tree removal year-round with a mild winter advantage. Dormant-season work between December and March can reduce scheduling pressure and simplify access in deciduous canopies, while the period from late June through November carries an elevated risk of tropical storm and nor’easter activity that drives emergency demand. Remnants of Atlantic hurricanes have historically produced widespread tree damage in the Baltimore-Washington corridor, the Chesapeake Bay shoreline, and the lower Eastern Shore.
Confirming that a contractor holds a current Maryland Licensed Tree Expert number is the single most important step before approving any tree work. The DNR Forest Service maintains a searchable database of nearly 600 active Licensed Tree Experts statewide, organized by company name, county, and license number. Beyond verifying the license, request a certificate of insurance before work begins, and check references with the contractor’s local Better Business Bureau to evaluate past performance and complaint history. The density of qualified firms across the Baltimore, Annapolis, Columbia, and Silver Spring markets means property owners can readily compare credentials and pricing without settling for an unlicensed operator.

Frequently Asked Questions About Tree Removal in Maryland
Q: What is a Maryland Licensed Tree Expert?
A Licensed Tree Expert (LTE) is a credential issued by the Maryland Department of Natural Resources Forest Service under Natural Resources Article Section 5-418. Anyone performing tree care or removal for compensation in Maryland must hold this license. To qualify, an applicant needs either two years of relevant college education plus one year of supervised practice under an existing LTE, or three years of continuous practice under an LTE. Candidates must pass a DNR-administered exam, carry liability and property damage insurance, and renew every two years with eight continuing education units.
Q: How can I verify that a tree company is licensed in Maryland?
The DNR Forest Service maintains a searchable online database at its Tree Expert Search page, where you can look up companies by name, county, or license number. Every Licensed Tree Expert carries a wallet card displaying a three-digit license number. You can also call the DNR Forest Service directly at (877) 620-8367 to confirm a contractor’s current license status and insurance compliance.
Q: Do I need a permit to remove a tree on my property in Maryland?
Requirements vary by jurisdiction. Trees on private property in unincorporated areas may not require a permit unless they fall under a local tree protection ordinance, such as those in Montgomery County or Prince George’s County that regulate removal of significant or specimen trees. Trees located within a public road right-of-way always require a Roadside Tree Care Permit from the DNR Forest Service. Baltimore City requires permits for any work on street trees managed by the Department of Recreation and Parks.
Q: Does homeowners insurance cover tree removal in Maryland?
Most standard homeowners policies in Maryland cover removal of a tree that has fallen onto a covered structure, such as the dwelling, garage, or fence, up to your policy limits and subject to the deductible. Many policies also include a modest allowance, often $500 to $1,000, for removing a fallen tree that blocks a driveway or accessible walkway even if no structure was damaged. Preventive removal of a standing tree that has not yet caused damage is generally not covered. Reviewing your specific policy language with your insurance agent before scheduling elective removal is advisable.
Q: What trees cause the most problems for Maryland homeowners?
Bradford pear, widely planted in suburban developments across the Baltimore-Washington corridor from the 1980s onward, is notorious for splitting apart under moderate wind loads due to its tight branch crotch angles. Silver maple grows rapidly but produces brittle wood prone to storm breakage. White pine can develop root plate failure in saturated clay soils common in the Piedmont. On the Eastern Shore, loblolly pine weakened by southern pine beetle or ice loading frequently requires emergency removal after nor’easters.
Q: When is the best time to remove a tree in Maryland?
Tree removal can be performed year-round in Maryland’s temperate climate, but the dormant months from December through early March offer practical advantages. Leafless canopies reduce weight and improve visibility for rigging cuts, and frozen or dry ground better supports heavy equipment. Scheduling outside the peak storm season also avoids the backlog that follows summer thunderstorms and fall hurricanes, when emergency calls consume most contractor capacity.
Q: What are the penalties for unlicensed tree work in Maryland?
Performing tree care or removal for compensation without a Maryland Licensed Tree Expert license is a criminal offense. A conviction is punishable by a fine, imprisonment of up to one year, or both, plus court costs. The DNR Forest Service investigates complaints and can pursue enforcement action against unlicensed operators. Property owners who hire unlicensed contractors risk voiding any recourse if damage occurs, since unlicensed companies may not carry the liability insurance that the LTE program requires.
