Central Texas · Edwards Plateau
Surveys can only be conducted between March 15 and June 1, and only by a biologist holding a federal recovery permit. I hold that permit.
Why this matters for your project
The golden-cheeked warbler is federally listed as endangered and nests only in Central Texas. Projects that may affect its habitat can raise Endangered Species Act questions, but the answer depends on the confirmed facts and the applicable regulatory path.
Planning range
Gold marks the 35-county breeding-range study area identified in the 2025 U.S. Fish and Wildlife Service status review. County location alone does not create a federal assessment requirement; review depends on federal involvement, suitable habitat in the action area, the proposed disturbance, and timing.
Planning context only: only part of some counties lies within the known breeding range, and county shading does not establish habitat on a specific property. Source: USFWS 2025 Golden-cheeked Warbler 5-Year Status Review.
My role is to evaluate habitat, conduct authorized surveys under current USFWS protocols, and document what is found. I do not issue clearance or decide whether a project is legally compliant; that determination belongs to the project team with the relevant agencies and, when needed, counsel.
There is usually more than one way through. Some Central Texas counties have regional conservation plans offering a fee-based participation route; many do not. Where habitat is present and impact is unavoidable, credits from an approved conservation bank are sometimes an option. And where the vegetation does not actually meet the habitat criteria, a documented assessment can end the question entirely.
Which of those applies depends on the county, the parcel and the project — and it is worth knowing before you plan a clearing schedule rather than after.
Oak-juniper woodland in Central Texas · April 2026
From the field
Rather than describe it, here is the habitat itself — the oak-juniper woodland the warbler depends on, and what a surveyor is looking at when deciding whether a property needs a full survey or a habitat assessment.
Short answers to the questions that come up most: whether you need a survey if you are not removing trees, what the window means for your schedule, what happens when the weather turns, and what to do if you miss it.
The thing people say out loud
You will hear this at closings, in contractor groups, and across fences. It is wrong — but it is wrong for a reason that makes sense, and it is worth understanding before you plan around it.
The golden-cheeked warbler is still listed as endangered. There is genuine movement: the Service’s five-year review in January 2025 recommended downlisting it to threatened, and a petition to delist it passed its initial finding and sits in a twelve-month review. That is a real process with real people behind it. It has not changed anything yet.
Mostly from a different bird. The black-capped vireo — a Central Texas songbird whose range overlaps the warbler’s and which comes up in the same habitat conversations — was genuinely delisted in 2018 after recovering. Two small birds, two very different legal statuses, one muddled conversation. When someone tells you “that bird got taken off the list,” they are often remembering the vireo.
Threatened does not mean unprotected. Protections for threatened species generally continue unless the Service issues a species-specific rule relaxing them, and that decision would be made as part of any downlisting rather than automatically. Treating “threatened” as “no constraint” is a bet on a rule that does not exist yet.
In plain termsThe bird might come off the endangered list one day. It has not. Scheduling a clearing crew around a rule change that has not happened is a way to be wrong at your own expense — and if it does change, nothing you spend on a desktop screening this winter is wasted, because you will have documentation either way.Status as of August 2026. This is a live proceeding — if you are reading this much later, check the current listing before relying on it.
The survey window
Miss it and the answer waits a full year. Because each site needs five spaced visits inside that window, spring capacity is limited and typically committed by February.
Not sure a survey is warranted?
Not every property with junipers is warbler habitat. Stands under 15 feet, pure juniper with no hardwoods, and open woodland below about 35 percent canopy cover generally are not.
A golden-cheeked warbler habitat assessment evaluates the vegetation on your property against the Service's habitat criteria and produces a documented report — and unlike a survey, it is not restricted to the spring window.
If a property meeting the habitat description is not surveyed, that assessment report goes to the USFWS Austin field office for review. Note that the Service does not issue concurrence on habitat assessments; the report documents the basis for the determination and the record of its submission.

Deliverables
The Service's reporting requirements are specific about format, and meeting them is part of the work rather than an extra.
Observation data and survey-area boundaries are submitted as GIS feature classes and shapefiles — the Service's stated preference over spreadsheets — following the current GCWA observation and survey-area reporting instructions. Habitat assessments can be submitted the same way, with the required detail carried in the attribute table.
Data are collected in the field in ArcGIS, in lat/long NAD 83, which is the datum the Service prefers.
Mapping is produced in ArcGIS Pro: property location within the county, dated aerial imagery with the boundary delineated, surveyed areas clearly bounded, and — where surveys are positive — detections and approximated territories.
For cartography beyond the standard reporting set, I work with a GIS specialist rather than approximating it.
Survey reports, habitat assessment reports with the reasoning behind the determination, and the annual narrative report to the Austin field office. Written so that a reviewer, a lender, or the next consultant can follow what was done and why.

Start small
Most people who call me do not need a full presence/absence survey. They need to know whether they need one. These are three separate products, in increasing order of cost and commitment — and many projects stop at the first.
Before anyone walks the property. I review current and historical aerial imagery, canopy cover, slope and drainage, county habitat mapping and the Service's range data against the published habitat criteria, and tell you what I see.
No site visit. No season. Often it is enough to tell you whether this is a real problem — and if it is not, you have saved everything downstream.
You receive
If the desktop review is inconclusive, or a reviewing agency wants documentation, I walk the property and assess the vegetation against the habitat criteria — juniper maturity, hardwood mix, canopy cover, topography — and produce a documented report.
Not restricted to the spring window. If a property meets the habitat description and is not surveyed, this report goes to the USFWS Austin field office. The Service does not issue concurrence; the report documents the basis for the determination.
You receive
Only if the habitat is there. Five visits minimum, five days apart, at least 60 percent of them before May 15, to the Service's protocol — with observation and survey-area data reported to the Austin field office by June 30.
Plan for three years. In most cases the Service requires three consecutive years of negative results before inferring absence, so this is usually a multi-season sequence rather than a single engagement.
You receive
If you are not sure where to start, start at step one. It takes days rather than seasons, and it is the conversation I would rather have in December than in April. Every quote states exactly how many site visits are included and what happens if weather costs one — because under this protocol, weather does cost them.
Common questions
These are the questions that come up in contractor groups and on first phone calls — usually answered badly, and often expensively.
Possibly, and it is worth finding out rather than assuming. Two things drive the answer, and neither is simply whether trees come down. First, your city or county may require habitat verification as a condition of a permit regardless of your scope of work. Second, the Endangered Species Act defines take to include habitat modification that disrupts breeding, feeding or sheltering — which can be broader than felling trees.
The Service also recommends looking at suitable habitat within 300 feet of the project area, not only inside your property line. A short conversation about what you are doing and where usually settles it.
Not every property with cedar on it is. The criteria are specific: mature Ashe juniper roughly 15 feet or taller with a trunk around 5 inches through, mixed with oaks and other hardwoods, canopy cover generally above 35 percent, typically on slopes and in canyons.
Young juniper in an old field is generally not habitat. Pure cedar with no hardwoods is generally not habitat. Open savannah below 35 percent canopy is generally not habitat. If your land was cleared years ago, there is a real chance it no longer meets the description — and documenting that is far cheaper than assuming the worst.
A desktop screening is usually the fastest first review. I can compare aerial imagery, canopy, and terrain with the biological criteria without anyone setting foot on the property, then recommend whether further review appears warranted.
It depends on acreage, access and how much of the property is potential habitat, because the protocol sets the effort: roughly one hour of survey time per 25 acres of potential habitat, per visit, with a minimum of five visits.
A habitat assessment is a fraction of a survey season and may be the right first step. If it documents that the assessed area does not meet the habitat criteria, the report gives the project team a biological basis for its next decision; it does not itself issue legal clearance.
For a survey, you wait a year. March 15 to June 1 is the only window, and there is no expedited option — the birds are in Mexico and Central America the rest of the year.
A habitat assessment is not seasonal, which is why winter is a sensible time to screen whether a survey may be warranted. Addressing the biological question in December is a great deal calmer than discovering an information gap in April.
In some counties, yes — Travis, Williamson and Bexar have regional conservation plans with a fee-based participation route, and for some projects that genuinely is the better deal. Most Central Texas counties have no such option.
One detail worth checking before you assume the fee is cheaper: in Travis County the mitigation fee is calculated on the entire legal tax parcel, not only the portion you are disturbing, and the rate is higher for land mapped as confirmed habitat than for unconfirmed. On a large parcel that arithmetic can change quickly. Confirm current figures with the county and run both numbers before deciding.
There is a real process underway. The Service's five-year review in January 2025 recommended downlisting the species from endangered to threatened, and a petition to delist it passed its initial finding and is in a twelve-month review.
But nothing has changed yet, and a change to threatened status would not automatically remove the requirement. Planning a clearing schedule around a rule change that has not happened is a way to be wrong at your own expense.
Five visits minimum, with at least five days between any two of them, so a single site occupies three to four weeks of the season at the very least — and at least 60 percent of those visits must fall before May 15.
That is why permitted surveyors are usually committed by February. If your project may need spring survey work, autumn is when to have the conversation.
The morning is lost, and that is not a judgment call. The Service's requirements state that surveys "must not be conducted during unfavorable weather conditions, such as (1) wind speeds greater than 12 miles per hour, (2) fog, (3) light to heavy precipitation, and (4) temperatures less than 45°F or greater than 80°F." The same document adds that surveyors "must not conduct surveys when experiencing temporary hearing impairment, such as from illness" — these are listening surveys as much as looking ones.
Practically: if the weather turns, the visit does not count toward the five required for that site, and it has to be made up. Because no two visits may fall within five days of each other and at least 60 percent must be done before May 15, one rained-out morning in April can push a whole schedule. This is the real reason spring capacity gets committed early — a permitted surveyor has to hold slack in the calendar for weather, and there is only so much slack in eleven weeks.
Yes, and you should know that up front. Survey data goes to the USFWS Austin field office by June 30 each year. Habitat assessment reports go in within five business days of the determination. Those reports may be disclosed under the Freedom of Information Act.
For work conducted under my federal permit, these submissions are permit conditions. Other consultants may operate under different authorizations or scopes, so the correct question is which permit or project condition applies — not whether someone else follows my workflow. My deliverable gives you a documented biological record rather than an assumption.

A short conversation about the property, the county, and your clearing schedule is usually enough to identify likely biological issues, information gaps, and practical next steps.
