The SRWHMG’s Case for Renewal, Examined

A Logical Analysis of the Salt River Wild Horse Management Group’s Argument for Renewal

The Salt River Wild Horse Management Group (SRWHMG) overseeing the Salt River horse herd has staked its bid for contract renewal on a bold claim: that its “humane management without removal” strategy is working. This message is prominently featured on their website, echoed in their petition to government agencies, and repeated frequently by their supporters. At the heart of the Management Group’s claim is the assertion that they have reduced the herd by 40% through humane, science-based fertility control—without removals—and that this success proves their model works.

Given that this supposed success is the foundation of their appeal for continued authority, it is not just reasonable—it is necessary—that their claims be subjected to independent scrutiny. If contraception alone is responsible for the decline, the data should make that outcome unmistakable. But if the numbers tell a different story, then the justification for extending their management contract collapses.

Logically, the MG’s argument depends on two key premises: (1) that the herd has, in fact, been reduced, and (2) that the reduction was achieved solely through contraception. Their conclusion—that their model works and warrants renewal—follows only if both premises are true. And for the argument to be sound, those premises must be proven by transparent, credible data—not just asserted.

Because the future of the Salt River horse herd matters deeply to the people of the Valley, any group seeking continued authority over its management must be held to the highest standard of truth and transparency. When a group makes bold claims about success, the public has the right—and the responsibility—to ask whether those claims are supported by evidence. The central question is whether the herd has, in fact, been reduced—and if so, whether that reduction can rightly be attributed to the “humane management without removal” approach the Management Group insists it has implemented.

The answer to the first part of the question is straightforward: yes, the herd has been reduced.
The Management Group reported:

• 401 horses on January 1, 2019
• 282 horses on December 31, 2024
• Total reduction: 119 horses

This is the figure they highlight repeatedly—on their website, in their petition, and in public messaging—to argue that their “humane, science-based” approach is working. It’s the cornerstone of their bid for contract renewal, and in this respect, they are both accurate and correct: the herd is smaller now than it was in 2019.

The next question is whether that reduction happened the way the Management Group says it did—through humane, non-removal methods, especially fertility control. That claim is central to their public narrative and their request to remain in charge. To evaluate it fairly, we need to look closely at what the numbers actually show over time.

Here is what the Management Group reported from 2019 through 2022:

• January 1, 2019: 401 horses
• December 31, 2019: 449 horses

• December 31, 2021: 438 horses
• December 31, 2022: 415 horses

Over this four-year period, the herd did not decline. It increased slightly—by 14 horses overall. While there were minor year-to-year fluctuations, there is no indication during this period of any sustained reduction. The population remained stable, and the Management Group reported no major losses.

Then, something changed.

• January 1, 2023: 415 horses

• December 31, 2023: 315 horses

In the span of a single year, the herd plummeted from 415 to 315 horses—a loss of 100 horses with no warning, no explanation, and no precedent. After four years of relative calm, this sudden collapse wasn’t gradual or controlled. It was abrupt, dramatic, and impossible to ignore.

What happened in 2023? That’s the question. Because if the Management Group is right—if this was the result of humane, science-based fertility control—then the data should clearly show it.

Let’s look at what they actually reported.

According to the Management Group’s own 2023 year-end update:

“At the beginning of 2023, the Salt River Herd count was 415.”

But later in that same report, they wrote:

“48 stallions and 52 mares were deleted from the herd count, totaling 100 horses.”

Why were they deleted? Not because of fertility control. Not because of natural attrition. The explanation, in their own words:

“Many bands… never came back to the TNF… These horses historically migrated back and forth but may have been stopped from coming back by the boundary fencing… At this time those bands of horses will be deducted from the herd count and will be considered reservation bands.”

In short, the horses didn’t die. They weren’t prevented from being born. They relocated themselves to the Reservations. This wasn’t population management. It was an accounting decision.

The result: a starting count of 415 became, on paper, 315. Not because of any “humane, science-based” strategy, but because 100 horses were administratively erased after leaving the area.

And yet—in the same report—the Management Group declared:

“At the beginning of 2023, the herd count was 415 horses. At the end of 2023, the Salt River herd size is 311. This continues the negative growth rate for the fourth year in a row.”

This is not just misleading—it’s logically incoherent. The 100-horse drop was not the result of negative growth. It was the result of a single internal reclassification.

A similar bookkeeping reduction occurred in 2024. In their year-end report, the Management Group acknowledged that although the official count at the end of 2023 was 311 horses, this number included 15 horses who had not returned to the forest. As they wrote:

“In our SRWHMG count, we ended 2023 with 311 horses, of which 15 horses were still included, who did not return to the forest this year, resulting in 296 horses currently.”

Once again, the drop was not caused by birth control or natural loss. It was produced by removing horses from the count after they failed to return, continuing the same pattern of redefining the herd through administrative adjustments rather than population management.

What they are calling a successful reduction is, in reality, a paper loss. A herd redefined—not reduced.

Here is what the numbers show:

• Starting herd size (January 1, 2019): 401 horses
• Ending herd size (December 31, 2024): 282 horses
• Total reduction: 119 horses
• Removed through bookkeeping reclassification: 115 horses
• Actual reduction potentially due to human management: 4 horses
• Percentage of real decline: 1% per year over six years

In short, the true population reduction attributable to active, humane management is not the 40% they claim—but less than 1% annually.

In the end, the Management Group’s argument fails on its own terms. 

• They claim credit for a population reduction they did not cause, and they cite numbers that were not the result of management, but of quiet reclassification. 
• Their core assertion—that humane, non-removal methods have successfully reduced the herd—is not supported by the data they themselves provide. 

An argument built on false premises cannot stand, and a management strategy that relies on erasing horses from the record cannot be called a success. If this is the foundation on which they seek renewal of their contract, then that foundation is not just shaky—it is broken.
