Montgomery County’s Forest Conservation Law (last updated April 3, 2023), which is based on Maryland’s Forest Conservation Act , aims to protect, plant, and maintain trees and forests for the many benefits they provide to county residents. The latest version of the Forest Conservation Law includes amendments intended to achieve no net loss of forest in Montgomery County.
The Forest Conservation Law applies to some property owners, government entities, and developers who need approval for a development plan, sediment control permit, or activity that could potentially harm a champion tree. Certain projects may qualify for an exemption from the requirements of preparing, submitting and implementing a Forest Conservation Plan. To find out whether the Forest Conservation Law applies to you, check out the General Decision Tree or Single Lot Decision Tree , and learn more about the different plan types .
Anyone subject to the Forest Conservation Law must meet a calculated forest retention or forest planting requirement. This requirement is met through planting or protecting forests with forest conservation easements , purchasing credits from one of the county’s forest mitigation banks , or contributing to the county’s Forest Conservation Fund .
Since the Forest Conservation Law first went into effect in 1992, the Planning Department has approved development applications that have permanently protected over 12,500 acres of existing forest and more than 2,500 acres of planted forests within more than 3,500 forest conservation easements across Montgomery County.
If you witness a potential forest conservation easement violation, such as permanent structures, mowing, grading, paving, construction, or tree removal, you can report a violation to our inspection team .
Frequently Asked Questions
Is the County’s Forest Conservation Law the same as the State of Maryland’s Forest Conservation Act?
The County’s Forest Conservation Law is based on the State of Maryland’s Forest Conservation Act (enabling legislation) and must be at least as strict as this state law.
Which projects are subject to the County’s Forest Conservation Law?
Owners of properties greater than 40,000 square feet who are required to submit a development application, a conditional use (special exception) application, or obtain a sediment control permit; any project that would threaten any champion tree; highway construction projects; and public utilities; must comply with the County’s Forest Conservation Law. Depending on the type of project and/or amount of forest proposed to be removed, the applicant may qualify for an exemption from submitting a Forest Conservation Plan.
Is all forest in Montgomery County regulated through the County’s Forest Conservation Law?
No. The Forest Conservation Law only applies to properties that meet the above requirements for size and application type. Additionally, State or federal projects that propose removal of forest are not subject to the County’s Forest Conservation Law but may be subject to the State of Maryland’s Forest Conservation Act. The Montgomery County Planning Department also does not implement the County’s Forest Conservation Law in certain municipalities, including Rockville, Gaithersburg, Poolesville, Laytonsville, Washington Grove, and Barnesville.
If a person subject to the County’s Forest Conservation Law (developer, property owner, or County representative) proposes a project that requires approval of a Forest Conservation Plan, how much forest are they required to protect or replant?
Every project that is required to submit a Forest Conservation Plan for review will have a different forest mitigation requirement, depending on the total tract area, area of existing forest cover, area of forest to be cleared, and land use category.
For example, a development project on a 16-acre property with a land use category of medium-density residential and 8 acres of existing forest that proposes to clear all 8 acres would have a forest mitigation requirement of 9 acres. If the same project were proposed on property with a land use category of agricultural and resource areas, the project would have a forest mitigation requirement of 16 acres.
