Gopher tortoises (Gopherus polyphemus) dig burrows in sandy uplands across the southeastern Coastal Plain. On Gulf projects from the Florida panhandle through coastal Alabama and Mississippi — and on related work farther into the Southeast — a tortoise survey is often the species question that shows up before clearing, borrow pits, utility corridors, and large pads.
This page is about when surveys are triggered and what a burrow survey is at a high level. It is not a take-permit how-to and not a substitute for current U.S. Fish and Wildlife Service or state guidance. For the federal statute frame, see Endangered Species Act: key protections explained.
ESA and state context on the Gulf
Federal status for gopher tortoise varies by range unit. Western and eastern populations have been treated differently under the ESA over time; listing and candidate history is not static. State wildlife agencies in Florida, Alabama, Mississippi, and Louisiana also regulate take, relocation, and permitting for tortoises and burrows under state law.
The practical point for a site: you may have a federal consultation issue, a state authorization issue, both, or neither — depending on where the property is, what is present, and whether a federal nexus exists (for example a Corps 404 permit in Mobile, Vicksburg, New Orleans, or Jacksonville District). Do not assume “not federally listed here” means “no survey and no state rules.”
Cypress flags tortoise habitat when the soils, canopy, and land use match what tortoises use. We do not invent district-by-district secret policies on this page.
When a project triggers a survey
Common triggers:
- Suitable habitat on or next to the limits of disturbance. Well-drained sandy soils, open or semi-open canopy, and ground cover tortoises can use — including rights-of-way, pine plantations with the right structure, dunes, and old fields.
- Agency or local reviewer request. Corps, state environmental agencies, or local governments often ask for a tortoise/burrow survey when the habitat is obvious on aerials.
- Federal nexus. A 404 permit, other federal funding, or federal land action can pull ESA Section 7 consultation into the timeline if listed species or critical habitat may be affected.
- State program rules. Florida in particular has well-developed tortoise survey and relocation practice tied to development; Alabama, Mississippi, and Louisiana have their own wildlife rules that can attach even when the Corps is not in the file.
A wetland delineation does not replace a tortoise survey. Different resource, different methods. See wetland delineation.
Burrow surveys and scope (high level)
Field work for tortoises on development sites is usually a pedestrian burrow survey of the area to be cleared or graded, plus a buffer the reviewing agency expects.
At a high level, crews walk transects spaced to the cover and visibility on site, mark burrows, classify activity signs when the method calls for it, and map locations against the project limits. Scope includes who walks what acreage, whether a second season or resurvey is needed after a long gap, and how staging and access limits are handled so the survey matches the dirt work.
Season and detectability matter. Tortoise activity and the ease of finding burrows vary with temperature, vegetation, and recent fire or mowing. Agencies publish timing and method expectations; those documents change. We follow the current protocol the reviewer named — we do not freeze a blog post as the method.
Camera work, scoping burrows, or trapping are separate scopes when a reviewer or permit condition requires more than a presence/burrow map. Relocation and incidental take authorization are permitting paths, not survey methods. This page stops at survey.
What a survey is not
- Not an incidental take permit or a relocation authorization
- Not a guarantee that no tortoise will walk onto the site after the survey date
- Not a Phase I Environmental Site Assessment
- Not optional because the aerial “looks too wet” if sandy inclusions and berms are in the footprint
If burrows are present, the next conversation is avoidance, minimization, and the correct state or federal authorization — with the agencies that actually have jurisdiction.
How we use it
We scope habitat, run burrow surveys when the project needs them, and fold the results into the permit or clearing schedule so the species question is not a surprise at mobilization. Cypress Environment & Infrastructure works from Biloxi, Mobile, and Pensacola, in the Mobile, Vicksburg, New Orleans, and Jacksonville Districts when a Corps nexus is in play, and on species work throughout the southeastern Gulf Coast. Office hours are Monday–Friday, 9 a.m.–5 p.m.
