- A gopher tortoise burrow has a flat-bottomed half-moon entrance with a fan of loose sand.
- Active and inactive burrows are treated as occupied; abandoned (caved/overgrown) ones aren't counted.
- Armadillo holes are round and clustered; owl burrows are smaller with debris; pocket gophers leave no open hole.
- Never fill or disturb a suspected burrow - photograph it and ask first.

Before you panic about the hole in your yard - or assume it's nothing - learn to read it. Correctly identifying a gopher tortoise burrow (versus an armadillo hole, a burrowing owl, or an old abandoned den) tells you whether the law is even in play.
The gopher tortoise signature
A gopher tortoise burrow has one unmistakable feature: a half-moon-shaped entrance - flat across the bottom, domed on top, matching the shape of the tortoise's shell. The opening is roughly as wide as the tortoise is long (often 6–15 inches), and there's usually a fan-shaped apron of loose sand spilling out from the mouth where the tortoise pushed soil out.
Active, inactive, or abandoned?
| Class | What you'll see | What it means |
|---|---|---|
| Active | Clean, defined opening; fresh sand apron; tracks or scat; no leaves/webs across the mouth | A tortoise is using it - treat as occupied |
| Inactive | Intact, correct shape, but leaf litter or a spider web across the entrance; no fresh sand | Usable and potentially occupied - still counts |
| Abandoned | Caved-in, cratered, or fully overgrown; loses the half-moon shape | No longer functional - not counted toward population |
Don't rely on "I never see a tortoise." They spend most of their lives underground and can sit tight for weeks. An intact burrow is assumed occupied until proven otherwise.
Telling it apart from look-alikes
Armadillo burrows
Round (not half-moon), irregular, and usually in clusters - an armadillo digs several. No consistent shape, and often dug right up against structures or tree roots.
Burrowing owl burrows
Much smaller and rounder, frequently ringed with debris, feathers, or dung the owls collect, and the owl is often standing sentry nearby. Protected under different rules - a key distinction in Cape Coral, where both species share neighborhoods.
Pocket gopher mounds
The "sandy mole" - throws up fan-shaped mounds of sand with no open entrance. If there's no visible hole, it's not a tortoise.
What burrow size and count tell you
Entrance width scales roughly with the tortoise's own shell length, so a wider half-moon opening generally means a larger (often more mature) tortoise, while several narrow openings clustered together can indicate juveniles. Two things worth knowing before you start counting burrows as tortoises:
- One tortoise, multiple burrows. A single gopher tortoise typically maintains and rotates between several burrows across its home range - burrow count on a property is not the same as tortoise count. This is exactly why a proper survey does more than tally holes; it classifies each one and correlates activity to estimate the actual population.
- Depth isn't visible from the surface. Burrows commonly run well beyond the visible entrance - length and depth vary by soil and individual tortoise, and there's no way to judge total tunnel length by eye. This is part of why FWC requires a trained surveyor's assessment rather than a homeowner's visual count for permit purposes.
Seasonal activity patterns
Gopher tortoises are most visibly active during Florida's warmer months, when they bask near the burrow entrance and forage on nearby low vegetation - this is the easiest time to spot fresh sand aprons and confirm activity. In cooler months they retreat deeper and surface less often, which is exactly why "I haven't seen it in weeks" doesn't mean a burrow is abandoned (see the Active/Inactive/Abandoned table above) - activity level shifts with the season, not necessarily with occupancy.
What to do if you think it's a tortoise burrow
- Don't disturb it. Don't fill it, block it, or run equipment within 25 feet - that's illegal take even if you're unsure.
- Photograph it. A clear photo of the entrance lets us confirm the species remotely.
- Call before you dig. If a project is planned nearby, a $350 survey settles it definitively and, if it's clear, gives you documentation.
A DIY photo ID is a reasonable first step, but it can't replace a survey for permit purposes - FWC requires a documented burrow count, GPS-mapped locations, and an activity classification for every opening on the parcel, not just a species confirmation. See how a survey works for exactly what that involves.
