Fort Worth's Tree Protection: The Rules That Matter

Every city handles tree protection a little differently. In Fort Worth, Texas, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Protected Tree Species

Fort Worth's Tree Preservation regulations under the Unified Development Code (commonly cited as Title 17) protect heritage and historic trees including post oak, blackjack oak, bur oak, pecan, and bald cypress along the Trinity River corridor and in the Stockyards, with mitigation, replacement, and removal-permit rules.

Key details: Code reference: Fort Worth UDC Tree Preservation. Protected species: Post oak, pecan, bald cypress. Riparian focus: Trinity River corridor. Historic overlay: Stockyards Historic District. Mitigation: Replacement or Tree Fund payment.

Removing or topping a protected heritage species without a permit, encroaching inside a critical root zone during construction, ignoring required mitigation plantings, or refusing inspections triggers fines per inch removed and stop-work orders.

Tree Removal Permits

Fort Worth regulates tree removal through the Urban Forestry Standards in the Zoning Ordinance (Article 6, Division 2). A tree removal permit is required for removing protected trees on developed lots. Protected trees include any tree with a trunk diameter of 6 inches or more measured at 4.5 feet above grade (DBH). The permit is obtained through Development Services. Removal of protected trees without a permit can result in fines and required replacement plantings. Emergency removal of hazardous trees may proceed without a permit with documentation.

Key details: Protected Tree Size: 6 inches DBH or greater. Permit Required: Yes — through Development Services. Zoning Reference: Article 6, Division 2 (Urban Forestry). Emergency Removal: Permitted with documentation of hazard. Penalty: Fines and replacement plantings for unauthorized removal.

Unauthorized removal: $500 to $10,000 per tree depending on size and species. Replacement planting required at 2:1 or 3:1 ratio.

Heritage & Protected Trees

Fort Worth's Urban Forestry Standards provide enhanced protection for heritage trees. Heritage trees are defined as healthy trees with a trunk diameter of 24 inches or more DBH (diameter at breast height). Heritage trees receive the highest level of protection and cannot be removed except in cases of imminent danger, disease, or when no reasonable development alternative exists. Mitigation requirements for heritage tree removal are significantly more stringent than for standard protected trees, including replacement at a higher caliper ratio.

Key details: Heritage Tree Size: 24 inches DBH or greater. Protection Level: Highest — removal extremely restricted. Removal Exceptions: Imminent danger, disease, or no alternative. Mitigation: Higher replacement caliper ratio required. Standard: Urban Forestry Standards (Zoning Ordinance).

Unauthorized removal of heritage tree: $2,000 to $25,000. Damage during construction: $1,000 to $10,000 plus remediation costs.

This is one of the stricter rules in Fort Worth's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Tree Replacement Requirements

Fort Worth requires replacement plantings when protected trees are removed during development. The Urban Forestry Standards specify replacement ratios based on the size and type of tree removed. Generally, replacement trees must total the caliper inches of the removed tree. Heritage trees (24+ inches DBH) require replacement at a higher ratio. Replacement trees must be from the city's approved species list and be a minimum caliper size. If on-site replanting is not feasible, developers may pay into the city's tree mitigation fund.

Key details: Replacement Ratio: Caliper-for-caliper (standard protected trees). Heritage Trees: Higher replacement ratio required. Minimum Size: Replacement trees must meet minimum caliper. Species: Must be from city-approved species list. Alternative: Payment to tree mitigation fund if on-site not feasible.

Failure to replace: $250 to $1,000 per tree plus required planting. Fee-in-lieu non-payment: lien on property.

The Bottom Line

Fort Worth's tree protection rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Fort Worth is broadly strict or permissive.

These rules come from Fort Worth's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
