Storm-Damaged Tree Assessment | Gulf Coast Alabama & Florida
After the Storm
Tropical Storm Isaias is forecast to strengthen as it approaches the northern Gulf Coast. Heritage Arborist is preparing for storm-damage work in North Alabama and independent storm assessments along the Alabama / northwest Florida Gulf Coast. Forecast details can change; follow NHC and your local NWS office for official warnings.
A Gulf Coast homeowner's ground check — what to look at, what it might mean, and when a tree needs a professional set of eyes.

Heritage Arborist is accepting independent storm-assessment requests from Fairhope through Pensacola: damaged-tree triage, written findings, second opinions, HOA / multi-tree prioritization and climbing inspection when conditions allow. This is a consulting-led Gulf Coast service. Major production removals remain with local tree crews.
Jeremy is scheduled for ISA Tree Risk Assessment Qualification (TRAQ) training and assessment later this month. Until successful completion is confirmed, Heritage will describe current work as professional arborist assessment - not a TRAQ assessment. Once confirmed, TRAQ services can be offered where that level of tree-risk assessment is appropriate.
Before anything else
Assume every downed or sagging line is live. Stay well clear, keep others clear, and call the utility. A limb resting on a conductor can energise the whole tree.
Do not walk under a hung-up limb to get a better photograph. Storm-broken wood sits under tension and lets go without warning.
Do not cut anything storm-damaged yourself. Bent, twisted and partially broken wood stores energy in ways that green standing timber does not. Chainsaw injuries spike after storms, and most of them happen to people cleaning up their own yards.
Everything in this guide is a ground observation. Nothing here requires you to climb, cut, or approach a leaning tree.
The first 48 hours: document before you clean up
The single most valuable thing you can do early is take photographs. Insurance questions, neighbour questions and arborist questions all get easier when there is a record from before anything was moved.
- The whole tree, from far enough back to see all of it. Stand where you can get the crown and the base in one frame. Take it from two or three sides.
- The base and the ground around it. Get down low. This is the frame most people skip and the one an arborist most wants.
- Anything that changed. A new crack, a lifted edge of turf, a limb that was not on the ground yesterday.
- The relationship to the house. One photo that shows the tree and the structure together, so scale and direction are obvious.
- A time reference. Your phone stamps this automatically. Do not strip it.
Write down the date, the storm name if it had one, and what you noticed. Memory blurs fast, and six months later during a claim or a sale, a dated note is worth more than a recollection.
The ground check: eight things to look at
These are observations, not verdicts. What follows each one is why an arborist cares about it — not a rating you should assign yourself.
1. The root plate and the soil around the base
Walk a full circle around the trunk. Look for soil that has cracked, heaved, or lifted on one side, turf that has torn, or a gap opening between the trunk flare and the ground.
Why it matters: Movement at the root plate means the tree's anchorage has been disturbed. UF/IFAS guidance treats a lifted root plate or severed major roots as a strong indicator for removal, because large severed roots rarely regenerate in a way that restores stability. This is one of the most serious things a homeowner can spot from the ground and one of the easiest to walk past.
2. Lean — and specifically, new lean
Many healthy trees have always leaned. What matters is change. Compare against an old photo, the line of a fence, or your own memory of how it looked from the kitchen window.
Why it matters: A lean the tree grew into over decades is a different situation from a lean it acquired on Tuesday. A tree that has newly moved toward a house, driveway or play area is the scenario UF/IFAS singles out for prompt professional attention.
3. Cracks in the trunk
Look for splits that run vertically, cracks that you can see into rather than just surface bark texture, and any seam that appears to pass through the wood rather than across it.
Why it matters: Trunk cracks extending deep into the wood are described in the UF/IFAS damage guidance as a severe defect warranting removal. Bark furrows and old healed seams are common and usually unremarkable; a fresh crack you can put a fingertip into is not.
4. How much crown the tree lost
Estimate roughly what fraction of the canopy is gone. You do not need precision — a quarter, a third, half.
Why it matters: The UF/IFAS research puts rough thresholds on this and they differ by species group: pines losing roughly 30–50% of canopy, and oaks losing roughly 50–70%, may be past reasonable recovery. Those are guidance ranges from published research, not a rule that decides your particular tree — age, prior health, structure and site all move the answer.
5. The size of what broke
Look at the diameter of the broken limbs, not just how many there are.
Why it matters: This is the distinction that most surprises homeowners. A tree that lost a lot of small branches is often an excellent candidate for restoration pruning over several years. A tree that lost limbs greater than about eight inches in diameter is a much more serious case, because wounds that size are slow to close and open a long-term decay pathway. A messy-looking tree can be in better shape than a tidy-looking one.
6. Hanging and lodged material
Look up. Note anything broken but still caught in the canopy, and anything resting on a roof, a line, or another tree.
Why it matters: This is the most immediate hazard to people on the property and it is entirely a ground observation. Note where it is, keep everyone out from under it, and do not attempt to pull it down.
7. What species it is — if you know
You do not need to identify it confidently. If you do know, it is useful context.
Why it matters: Species affects both how a tree survives wind and how it handles wounds afterward. In the coastal-plain research, live oak, sand live oak, southern magnolia, the hollies, and baldcypress and pondcypress consistently ranked among the highest in wind resistance. Laurel oak, water oak, pecan, Bradford pear, sand pine and southern red cedar ranked among the lowest. Among pines, slash pine survived better than longleaf, loblolly, sand and spruce pine. Species also differs in how well a tree walls off decay after injury: live oak compartmentalises well, laurel oak and water oak poorly — which is part of why the same wound is a bigger problem on some trees than others.
8. What is underneath it
Note what sits within falling distance: the house, a bedroom specifically, the driveway where cars park, a shed, a play area, a walkway, the neighbour's property.
Why it matters: Professional risk assessment does not evaluate a tree in isolation. It weighs how likely a failure is, how likely that failure is to strike something, and what the consequences would be if it did. A leaning tree over open pasture and the same tree over a child's bedroom are not the same problem, and they do not get the same recommendation.
What this guide will not do
It will not tell you your tree is safe. No guide can, and you should be sceptical of anything that claims to. Trees are living structures in a changing environment, and no assessment — not this one, not a professional one — removes risk or predicts the next storm.
It also will not tell you your tree has to go. That determination depends on things you cannot evaluate from a phone: the condition of wood you cannot see, the root system under the soil, the tree's structure above the point you can view from, and how all of it interacts with what is beneath the tree.
What a careful ground check does do is tell you whether the situation warrants a professional looking at it, and give that professional a far better starting point when they arrive.
Conditions that warrant professional attention
Any of the following is a reasonable trigger for having an arborist look at the tree:
- Soil lifting, cracking or heaving anywhere around the base
- A lean that is new, or a lean that has visibly increased
- A crack in the trunk that appears to extend into the wood
- Broken limbs larger than roughly eight inches in diameter
- Substantial crown loss, particularly on a pine
- Anything broken and still hanging in the canopy
- A tree that is over a structure, and that changed in any way during the storm
- A tree you have been told needs removal, where you would like an independent opinion first
- Damage you need documented for insurance, a sale, or a dispute with a neighbour
Restoring a damaged tree is often possible and frequently cheaper than removal and replacement — but the decision genuinely depends on the specifics, and the UF/IFAS guidance is explicit that evaluating risk, removing leaning trees, restoring damaged specimens and pruning high limbs are situations calling for an professional arborist rather than a homeowner or a general contractor.
Have an arborist look at it
Send the photographs you just took and a short description. You will get a straight answer about whether the tree warrants an on-site assessment — including if it does not.

Important. This guide is general educational material. It is not a tree risk assessment and does not replace a site-specific professional assessment of your tree by a qualified arborist. It does not evaluate any particular tree, and nothing in it should be read as a finding that a tree is safe, unsafe, or requires any particular action. Do not perform climbing, chainsaw, rigging or storm-damage clean-up work you are not trained and equipped for.
Need an arborist to look at the tree?
If the tree moved, cracked, lost major limbs, has hanging material, or sits over a house, road, parking area or other occupied space, request an independent assessment. For HOAs and multi-tree properties, Heritage Arborist can prioritize which trees need attention first.
