Australian pine: bottom of the wind charts, top of the removal list.
It’s not a pine, it’s not supposed to be here, and UF’s hurricane research ranks it among the least wind-resistant trees measured — shallow-rooted and brittle exactly where people love them, along canals and shorelines.
Australian pine combines the worst wind rating UF measured with the worst places to fail — waterfronts. It’s a prohibited invasive statewide, exempt from tree-removal permitting in most Pinellas jurisdictions, shallow-rooted, brittle, and overwhelmingly planted (decades ago) along the canals, seawalls and beaches where a whole-tree failure has no safe place to land.
Knowing your “pine”
It isn’t a pine at all — the “needles” are jointed, drooping branchlets and the “cones” are woody little seed capsules. The silhouette is unmistakable along older Pinellas waterfronts: tall, wispy, permanently wind-combed rows planted as fast shade and windbreaks in the mid-1900s, before anyone understood what they’d do. They cast dense shade, carpet the ground with allelopathic litter that suppresses everything else, and drop live and dead material constantly.
The wind problem, specifically
UF’s tropical wind-resistance research places casuarina in the lowest class rated — and its failure mode is the bad one: shallow root plates letting go, delivering the entire tree at once rather than shedding branches. The local pattern after every serious storm event matches: Australian pines across seawalls, docks, pool cages and roofs. A big one standing over anything you value is a decision that gets made either by you on a calendar or by weather on its own.
The permit picture
As a listed prohibited species, casuarina removal is permit-free or no-fee-permit nearly everywhere in the county — St. Petersburg and Clearwater list it as prohibited outright, unincorporated Pinellas issues the no-fee invasive permit, Pinellas Park can order removal on notice, and North Redington Beach’s entire tree code is essentially one line forbidding Australian pines over four feet tall. Your city’s page in our permit guides has the specifics.
The real DIY danger
Size and setting. These are 40-to-80-foot trees, usually leaning seaward, usually over water, seawalls or neighbors’ property — removal is rigging and rope work, occasionally barge-adjacent, never a weekend project. The wood is also deceptively heavy for how dead the tree looks. Homeowner-scale pepper removal exists; homeowner-scale casuarina removal doesn’t.
What shapes the cost
Position over water or structures is the whole story — a casuarina on open ground drops fast and cheap, while the same tree over a dock is a piece-by-piece dismantle with every section on rope. Rows price better per tree than singles. And as with every declining invasive: the price only goes up as the wood gets worse, and the storm never asks first.
Questions Cody hears every week.
If it's prohibited, why is it still standing in my yard?
The prohibition stops planting and sale — nobody makes you remove an existing tree. But insurers, neighbors downwind, and hurricane physics all argue for dealing with a big casuarina before a storm does.
Is it true they fall easier than other trees?
UF’s tropical wind-resistance study puts Australian pine in the lowest class they rate, and the pattern locals know matches: shallow root plates and whole-tree failures onto seawalls, docks and screen enclosures. Along water, there’s usually no good place for one to land.
Do I need a permit to remove an Australian pine?
Usually not — as a listed invasive it’s exempt in most Pinellas jurisdictions, same as Brazilian pepper. Check your city’s page in our permit guide; where an exemption needs species confirmation, our photo documentation covers it.
