Direct Answer & Local Summary
In the City of Fort Worth, an Urban Forestry permit is generally required before removing 'significant' or 'protected' native trees on properties subject to municipal tree canopy regulations. For most species, a tree becomes significant when its trunk measures 24 inches or greater in diameter at breast height (DBH, measured 4.5 feet above grade). For sensitive native oaks—specifically post oaks and blackjack oaks—the threshold is lower, at 18 inches DBH. However, trees that are dead, dying, severely diseased, or presenting an immediate hazard to human life or structures are typically exempt, though photographic documentation or a written arborist statement is strongly recommended prior to removal.

Fort Worth Urban Forestry Ordinance: Core Definitions
The City of Fort Worth enforces tree preservation standards under Ordinance No. 13837 and subsequent updates to Chapter 6 of the City Code. The ordinance aims to maintain a healthy urban tree canopy across Tarrant County.
Under city guidelines, trees are categorized by size and species value:
• Significant Trees: Native hardwood trees measuring 24 inches DBH or greater.
• Post Oak & Blackjack Oak Exception: Because post oaks and blackjack oaks are slow-growing Cross Timbers natives that are exceptionally difficult to replace, they are protected at 18 inches DBH.

How to Measure Trunk Diameter at Breast Height (DBH)
To determine if your tree meets the city's significant threshold, measure the trunk circumference at 4.5 feet above the ground using a standard flexible tape measure.
Divide the circumference measurement by pi (3.14159) to find the diameter. For example, a tree trunk with a circumference of 75.4 inches at 4.5 feet has a DBH of 24 inches (75.4 ÷ 3.14159 = 24), placing it within the city's significant tree category.
Common Exemptions: Dead, Diseased & Hazardous Trees
The City of Fort Worth recognizes that dead or structurally compromised trees present severe public safety hazards. You do not need to preserve a tree that:
• Is biologically dead or suffering from terminal vascular collapse (such as systemic oak wilt or advanced Hypoxylon canker).
• Has suffered catastrophic storm splitting or root plate lifting.
• Poses an imminent threat of falling on a residence, school, playground, or utility line.
Before cutting, take close-up photos of fungal rot, trunk cavities, or split wood to keep in your records should city code compliance inspect the property.
Texas Local Government Code §212.905 & Residential Rights
In 2017, the Texas Legislature enacted Texas Local Government Code §212.905, which restricts municipal tree preservation fees for existing single-family owner-occupied residential properties under certain lot size limits.
While commercial developers and new residential subdivision builders must submit detailed tree surveys and tree mitigation plans, existing residential homeowners enjoy greater flexibility when maintaining or removing trees on private lots.
Expert Compliance Insights: Navigating Fort Worth Urban Forestry Inspections
When dealing with mature trees in Fort Worth that approach the 24-inch DBH threshold (or 18 inches for native post and blackjack oaks), clear documentation is your strongest legal asset. Municipal code compliance officers rely heavily on physical evidence when verifying emergency removals.
Before removing a diseased or storm-damaged specimen, photograph the trunk diameter with a measuring tape visible, take close-up images of internal fungal conks or heart rot, and document structural leans toward residences. Having these files organized eliminates contentious permit disputes and prevents unexpected municipal mitigation penalties.
