Overpopulation and AMLs

AMLs are often expressed as a range, such as 120 – 200.

In this example, horse #121 is excess, the beginning of overpopulation according to current management practices.

The high end of the range usually corresponds to around 20% of the authorized forage.

The management plan allows 200 wild horses and livestock equivalent to 800 horses.

If the current population is less than 5X AML, the HMA is not overpopulated from a resource viewpoint, but the ranchers won’t be able to access all of the AUMs on their permits until corrective actions are taken.

The AML range usually allows for a doubling of herd size between those actions.

A narrow range means little if any growth.

The new AML at Pryor Mountain, 107 – 120, implies heavy use of fertility control pesticides and sterilization of mares, synonymous with conservation in advocacy circles.

Foal-Free Friday, Uproar and Outrage Edition

There is much distress among the advocates at the prospects of losing 3,700 wild horses in three HMAs in Wyoming, yet there is nary a concern about the fate of wild horses at the Salt River and Virginia Range.

There, the advocates are wiping out herds of approximately 300 and 3,400, respectively, by sterilizing the mares.

Why is the former considered eradication while the latter passes for conservation?

Scoping Begins for Lincoln County Public Lands Sale

The project covers the sale of approximately 5,500 acres in 66 parcels according to the BLM news release.

Some are the Caliente Complex.

The scoping report includes eight maps showing their locations.

To find them in the ArcGIS viewer, turn on the PLSS layer and zoom/drag the map to the township-range blocks indicated in the report.

To identify the overlapping herd areas and allotments, turn on those layers.

Draft EA for Rock Springs Wild Horse Removal Out for Review

An assessment of the environmental effects of zeroing out the Divide Basin, Salt Wells Creek and northern portion of the Adobe Town HMAs has been copied to the project folder for public comment.

Alternative II, discussed in Section 2.2, calls for the removal of all wild horses from the project area.

Map 1 shows the arrangement.

The preferred method would be helicopter drive trapping but roping and bait may also be used.

Operations would commence on July 15, assuming there are no major findings, and would continue until all wild horses are removed, which may require several years.

The comment period will close on April 30 according to the news release.

BLM Releases Pryor Mountain Final Planning Documents

They were copied to the project folder on March 17.

The Decision Record authorizes a change to the Billings Resource Management Plan regarding genetic diversity, to be followed by a similar decision from the Forest Service.

Other parts of the Proposed Action, discussed in Section 2.3 of the Final EA, will be covered by separate decisions.

Appendix I still refers to outdated registrations for GonaCon Equine. suggesting that accuracy is not a desired characteristic of the planning process.

Recent observations suggest that PZP causes reductions in ovary size and function, described by the writers as a “complementary hypothesis” in a discussion of the direct effects of the pesticide.

Contradictory might be a better term, a rebuttal of the sperm-blocking theory peddled by the advocates.

Adobe Town DNA Out for Public Review

The Proposed Action would gather and remove excess horses from the Adobe Town HMA and apply fertility control treatments of unspecified type.

The current population is thought to be 2,438.

No other documents were copied to the project folder.

The description does not indicate when the roundup would occur.

The deadline for submitting comments is April 28.

UPDATE: A map of the project area was not included in the DNA but the BLM news release suggests it applies to the portion of the HMA that will not be zeroed-out by the Rock Springs RMP Amendments.

Foal-Free Friday, Cycle of Dependency Edition

The advocacy groups rely on their misguided followers to sustain their ruinous agenda.

They’re constantly inventing new gimmicks to keep them engaged and their donations rolling in.

Wild Horse Protection Month 03-27-25

Their followers depend on the advocacy groups to validate their ill-informed notions about wild horses and the way public lands are managed.

Together, they support legislation that marginalizes the horses in favor of hunters and ranchers.

Some try to masquerade as independent voices but they arrive at the same conclusions and promote the same policies as the advocates, a phenomenon known as groupthink.

New Mexico Legislature Passes Wild Horse Bill

It’s headed to the governor’s desk according to a story by The Sandoval Signpost.

The bill targets free-roaming herds in Placitas and Ruidoso.

A similar measure passed in the Senate two years ago but did not advance.

Curiously, Placitas is surrounded by BLM grazing allotments.

UPDATE: Placitas in Sandoval County is not surrounded by allotments although there are a few to the north and east.
