In Jourdanton, a ranch that once ran as one operation is now being sold as nine. Goose Creek Ranch, an ag-exempt acreage community inside Jourdanton ISD, carves a tract of up to 1,237 acres into nine separate ranchette parcels. Nothing about that is unusual for Atascosa County right now. What's unusual is that a state research institute just handed everyone a name for why it's happening, and a way to see it coming before it shows up as a listing.
If you've spent any time pricing land in Atascosa County this year, you've probably noticed the numbers don't agree with each other. One aggregator will show you a county-wide average price per acre in the low $20,000s. Another will show you something closer to $16,000. A third will land near $12,000. Same county, same season, three different answers. That's not sloppy data collection. It's the market pricing something the acreage figure alone can't capture.
The Math That Doesn't Reconcile
Pull county-wide numbers from three separate land-listing aggregators in late August 2026 and you get roughly $11,700, $16,300, and $23,000 per acre, all describing the same 1,221 square miles of Atascosa County. That's close to a two-fold spread on paper for land that, viewed from a satellite, looks like the same brush country: flat plains suited to row crops in the west, rolling terrain suited to ranching in the east, and the San Antonio River and its tributaries running through the middle.
The usual explanation would be acreage mix. Smaller tracts carry a higher per-acre cost than large ones almost everywhere in Texas, so if one aggregator's inventory skews toward 10-acre homesites and another's skews toward 300-acre ranches, you'd expect the averages to diverge. That's real, but it's not the whole story here. Atascosa County has a second variable stacked on top of size, and as of late August 2026, there's a fresh piece of statewide research that names it directly.
What Texas A&M Just Confirmed
On August 25, 2026, the Texas A&M Natural Resources Institute published an update to its Fragmentation Risk Index, part of the long-running Texas Land Trends program. The index blends land value appreciation, the age of a county's farm and ranch operators, average operation size, and projected population growth into a single county-level score meant to flag where large working tracts are most likely to get sold off or divided next.
Eighteen counties statewide moved from the second-highest risk class into the highest this update. Atascosa County was one of them, alongside Kendall, Kerr, and Gillespie counties in the Hill Country, Hood and Rockwall counties near Dallas-Fort Worth, and Hidalgo County in the Rio Grande Valley. Collin, Denton, and Parker counties, all inside the expanding DFW metroplex, hold the maximum score. Atascosa now sits in the same risk tier as counties absorbing some of the fastest suburban growth in the state, and its explanation is the same one driving that DFW growth: a county sitting directly on the edge of a major metro, in this case Bexar County and San Antonio.
Statewide, the pressure behind that score is measurable. Between 2017 and 2022, Texas converted more than 1.8 million acres of working land and lost over 17,000 farm and ranch operations, according to the Land Trends program's most recent Ag Census analysis. Average appraised market value of Texas working lands rose from $1,951 per acre in 2017 to $3,021 per acre by 2022, a 55 percent jump in five years. Those are statewide figures, not Atascosa-specific ones, but they explain the incentive structure the fragmentation score is measuring: when land near a growing city gets more valuable every year, holding it whole gets more expensive relative to selling or subdividing it.
A ranch that has stayed in one family for three generations doesn't fragment because the land got worse. It fragments because the land got valuable enough that dividing it, or selling to someone who will, becomes the more rational move at the exact moment ownership passes to the next generation.
That's the mechanism behind Atascosa's new classification, and it's also the mechanism behind your three conflicting per-acre averages. A portal's number reflects whatever mix of intact ranches and freshly subdivided ranchettes happens to be listed that month. As more large tracts split into smaller ones, the blended average shifts, and it will keep shifting as this plays out.
Proximity Cuts Two Ways
Atascosa County isn't uniformly close to San Antonio. Current listings put commute times anywhere from 20 minutes to a full hour from downtown, depending on which part of the county you're in. A tract near I-37 in Pleasanton might sit 20 minutes from the city. A ranch outside Campbellton, further south, runs closer to an hour. That range matters more than it used to.
The closer a tract sits to San Antonio's growth corridor along I-37 and Loop 1604, the more its value is shaped by what it could become rather than what it currently is. A shovel-ready 14.56-acre tract along FM-1784 near Pleasanton, engineered for a 48,000-square-foot manufacturing facility and marketed at 20 minutes from downtown San Antonio, is priced for industrial conversion, not for row crops or cattle. That's a fragmentation-adjacent story too. Working land isn't just splitting into smaller ranches. Some of it is converting to a completely different use.
For a buyer who wants 300 intact acres for hunting, cattle, or a working operation, that same proximity works against you. You're now competing with buyers who see a tract's value in what it could be divided into, not what it currently produces, and that competition shows up as upward pressure on price even before you factor in improvements, water, or fencing. The counterintuitive part is that the safest bet for someone who wants land to stay whole for the next twenty years may not be the parcel closest to San Antonio. It may be the one thirty minutes further out, where the fragmentation math hasn't caught up yet.
The Ranch That's Already Splitting
Goose Creek Ranch is worth returning to, because it shows the abstract policy finding happening in real time rather than in a research paper. A holding of up to 1,237 acres in Jourdanton ISD is being marketed today as nine separate ranchettes, positioned as an ag-exempt acreage community rather than one ranch changing hands as a single deal. That's exactly the pattern the fragmentation index is built to flag: a working tract, in a county that just moved into the highest-risk class, getting divided into smaller ownerships that each carry their own ag exemption, their own access, and their own future buyer.
If you're evaluating a 300-acre or larger tract in Atascosa County right now, that's the scenario worth asking about directly. Is the current owner holding this as one operation, or is it already being packaged for a subdivision play? The answer changes what you're actually bidding against.
What This Means If You're Buying Or Selling
If you're the landowner whose family has held a ranch here for a generation or two, this research doesn't tell you what to do with it. It tells you that the economics around your decision have shifted, and that the shift has a name and a public data source behind it now. Land near the San Antonio corridor is worth more today than it was five years ago, and that value increase is precisely what makes selling or dividing more attractive at the moment ownership changes hands. Whether you treat that as an opportunity or a reason to hold the line depends on whether you're thinking about this parcel as an investment, a legacy, or both.
If you're the buyer looking for a weekend ranch or a working operation you want to keep intact, the practical move is to ask sharper questions before you fall for a per-acre number. How far is this tract from the I-37 or Loop 1604 corridor. Is it inside San Antonio's extraterritorial jurisdiction, which can affect future annexation and zoning. Is the surrounding land already showing signs of the same pressure, subdivided ranchettes, industrial-ready tracts, new fencing where a larger pasture used to be. None of that shows up in a portal's average price per acre, but all of it shows up in the deed history and the neighboring parcels if you know to look.
FAQ
Does a high fragmentation-risk score mean Atascosa County land is a bad investment? No. The score measures the likelihood that large working tracts get divided or converted, which is a different question from whether land values are rising. Proximity to a growing metro is generally what pushes land values up in the first place. The score is a signal about how the land around you may change, not a verdict on your own tract's value.
How do I find out if a specific tract is inside San Antonio's extraterritorial jurisdiction? ETJ boundaries and any related annexation plans are public record through the relevant municipal and county offices, and this is exactly the kind of detail worth confirming before you make an offer, since it can affect future permitted uses and tax exposure.
Where can I see the fragmentation data myself? The Texas A&M Natural Resources Institute publishes the Fragmentation Risk Index and the underlying Texas Land Trends research at txlandtrends.org, including the county-level mapping tool.
