Protected Tree Species: Removal Rules by State
From California native oaks to Arizona saguaros to Florida mangroves, protected tree laws can add five-figure penalties to an otherwise routine removal. Here is what is protected, who enforces, and what it costs if you cut first.
Quick Answer: Protection comes from three layers: state endangered species lists, state native plant laws (AZ, CA, HI), and city heritage tree ordinances. Penalties for unpermitted removal range from $500 per tree (most cities) to $60,000 or more (NYC street trees, LA protected oaks).
Three Layers of Tree Protection
Every protected tree falls under one or more of these. Knowing which applies to your tree tells you who to contact and what paperwork you will need.
Federal
Endangered Species Act, Lacey Act, and Section 404 of the Clean Water Act (wetland trees). Mangroves, Florida torreya, and certain rare species fall here.
State
Arizona Native Plant Law, California Desert Native Plants Act, Hawaii Exceptional Tree laws, Massachusetts MGL Chapter 87, Florida Mangrove Act. Each names specific species or categories.
City and county
Most tree protection in the US happens at the municipal level. Heritage tree ordinances, right-of-way rules, historic district overlays, and species-specific protections (Atlanta oak, Austin heritage, Seattle Exceptional) live here.
Protected Species by Region
Below is a region-by-region picture of commonly protected species. This is the starting point, not the full picture — always verify locally before cutting.
California and the West
- Native oaks: Coast live oak, valley oak, blue oak, Engelmann oak, California black oak. Protected by nearly every coastal and foothill city under a Protected Oak Ordinance. Threshold usually 6 to 8 inches DBH.
- Coast redwood and giant sequoia: Broadly protected in coastal counties. Removal of a mature redwood is legally difficult anywhere in California.
- Desert natives: Joshua tree (separately protected), ocotillo, desert ironwood, manzanita, Western Joshua Tree Conservation Act coverage in deserts.
Florida and the Southeast
- Mangroves: Red, black, and white mangroves are federally protected as wetland vegetation. Any trimming beyond 25 percent of canopy requires a state permit.
- Live oak and cypress: Protected by most Florida, Georgia, and coastal Louisiana municipalities. New Orleans live oak removal is notoriously hard to get approved.
- Cabbage palm (sabal palm): State tree of Florida. Protected in specific conservation zones.
Texas
- Austin heritage trees (19 inch DBH): Live oak, post oak, bur oak, pecan, Arizona walnut, bald cypress, American elm, cedar elm, Texas ash, bigtooth maple.
- San Antonio heritage trees (24 inch DBH): Similar species list with a higher threshold.
- Dallas protected trees: Species and size matrix rather than a single threshold. Live oak and pecan protected at smaller sizes.
Arizona and the Desert Southwest
- Saguaro cactus: Protected statewide under the Arizona Native Plant Law. Cannot be moved, damaged, or destroyed without a salvage tag from the AZ Department of Agriculture.
- Ironwood, velvet mesquite, palo verde (both species), ocotillo: All protected native plants. Salvage tag and transport documentation required.
- Joshua tree (shared with CA and NV): Western Joshua Tree Conservation Act in California. Similar protections in parts of Nevada and Arizona.
Hawaii
- All native species: Koa, ohia lehua, wiliwili, loulu palm, hala, kou. Protected statewide. Federal Endangered Species Act overlay for threatened natives.
- Exceptional Trees: Each county (Honolulu, Maui, Kauai, Hawaii) maintains a list of individually designated Exceptional Trees that cannot be removed without county arborist committee approval.
Pacific Northwest
- Big-leaf maple: Actively protected due to illegal poaching for instrument wood. Lacey Act federal charges for trafficking.
- Douglas-fir heritage specimens: Individually designated in Portland, Seattle, and many mid-size cities. Old-growth specimens inside urban growth boundaries broadly protected.
- Western red cedar: Seattle Exceptional Tree list covers specific red cedars by size.
New England
- Public shade trees: Any tree within a public way in Massachusetts (MGL Chapter 87). Public hearing required before removal regardless of species or size.
- American elm: Replanting programs active in most New England states. Surviving mature elms often individually protected.
- Old-growth stands: Designated old-growth specimens of white pine, eastern hemlock, sugar maple, and yellow birch in state reserve zones.

How to Verify a Tree on Your Property
Before you even call a tree service, run this 15-minute verification.
Search your city website
Google "[your city] tree ordinance" or "[your city] protected trees." Almost every US city over 20,000 people publishes the list as a PDF.
Measure DBH
Measure the trunk circumference at 4.5 feet above ground using a flexible tape. Divide circumference by 3.14 to get diameter in inches. Multi-trunk trees usually measure each trunk, then combine per the ordinance formula.
Identify the species
Use a field guide, iNaturalist, or the Arbor Day Tree Identification Guide. If there is any chance the species is protected, pay an ISA Certified Arborist for a verification visit. Reports typically cost $150 to $300.
Check for overlays
Historic district, flood zone, coastal zone, or conservation easement overlays can add protection even for species that are not otherwise protected. Your city GIS portal shows these.
Call the city arborist
Most cities offer a free 15-minute consultation either by phone or a site visit. Tell them what you are thinking of removing and ask whether a permit is required. Get the answer in writing (email).
What Happens If You Cut a Protected Tree
A permit you skipped can become a six-figure problem for a mature heritage tree. Here is what cities actually charge.
- Fine per tree: $500 to $25,000 depending on species and jurisdiction. New Orleans caps live oak fines at $25,000.
- Caliper-inch valuation: NYC street trees use roughly $2,500 per caliper inch. A 24 inch tree triggers a $60,000 bill before replacement.
- Mandatory replacement at elevated ratios: Los Angeles requires 4:1 for protected oaks. Austin bases mitigation on total caliper inches.
- Criminal exposure: Lacey Act federal charges for big-leaf maple poaching. Endangered Species Act exposure for listed species.
- Civil liability: Neighbors, HOAs, and conservation groups can sue under public nuisance and private injury statutes in some states.

Frequently Asked Questions
How do I identify a protected tree on my property?
Start with your city website and search for "protected tree ordinance" or "heritage tree list." Most cities publish a species list with size thresholds. Measure the trunk diameter at 4.5 feet above ground (DBH). If the species is listed and the tree exceeds the threshold, it is protected. If you are unsure, an ISA Certified Arborist can identify the species and confirm in a single visit, typically for $150 to $300.
Can I hire an arborist to verify protected status before I apply?
Yes, and for any tree that could be protected, you should. An ISA Certified Arborist can identify the species, measure DBH, assess health, and produce a written report that doubles as supporting documentation for your permit application. Most cities accept arborist reports from any ISA-certified professional, not just city-contracted arborists.
What is the appeal process if my removal is denied?
Most cities offer a two-step appeal. First, request a reconsideration from the city arborist with additional documentation (hazard assessment, structural engineering report, new arborist opinion). If denied again, you can usually appeal to a parks board, planning commission, or city tree board. Appeals take 30 to 90 days and sometimes require a public hearing. Hearing fees run $250 to $1,000.
Does the rule change if the tree is diseased or dangerous?
Almost always yes. Nearly every protected tree ordinance has a hazard exemption. You still need to document the condition with an ISA Certified Arborist report, and many cities require a site inspection by their own arborist, but the fee is usually waived and approval is typically granted within a week. Emergency removals after storms are generally allowed with 72-hour after-the-fact notification.
What are the replacement requirements for a protected tree?
Replacement ratios run 1:1 to 4:1 depending on jurisdiction. Los Angeles requires 4:1 for protected oaks. Austin requires mitigation totaling the caliper inches of the removed tree. Seattle Exceptional Trees require replacement with comparable species. Where physical replanting is not feasible, most cities accept payment into a tree mitigation fund at $100 to $300 per caliper inch.
How does a tree get designated as a heritage tree in the first place?
Cities designate heritage trees in one of three ways: automatic designation by species and size (most common), individual designation by a property owner or a neighbor through a public nomination process, or designation through a historic district or landmark listing. Nominations are usually reviewed by a city arborist or tree board and require a public hearing before final designation.
Are there federal protections that overlap with state rules?
Yes. The Endangered Species Act protects individual species like Florida torreya and certain California manzanita. The Lacey Act criminalizes trafficking of illegally harvested wood, which has been applied to big-leaf maple poaching in the Pacific Northwest. Mangroves are protected federally as wetland vegetation. Wetland trees broadly fall under Section 404 of the Clean Water Act, administered by the US Army Corps of Engineers.
Can my HOA protect a tree that my city does not?
Yes. HOA authority is independent of municipal authority. An HOA can designate trees as protected under CC&Rs even if the city has no tree ordinance, and you would need HOA approval to remove them. Conversely, some state laws preempt HOA rules in specific cases (California Solar Rights Act, Arizona xeriscape laws) but most tree-related HOA rules are enforceable.
