Tamarack Fire Approaching Nevada State Line

The fire started on July 4, according to the overview at InciWeb, and was monitored until July 16 when rapid growth prompted the deployment of firefighting resources.

Douglas County, home of the Pine Nut and Fish Springs horses, is now threatened but no evacuation orders have been issued.

This video from Storey County, a few miles to the north, suggests that the Virginia Range mustangs are also affected.

Onaqui Aftermath

A report by The Salt Lake Tribune says that 126 of the 433 horses shipped from the HMA will be returned, including mares treated with PZP.  The 307 remaining will be offered for adoption or placed into long-term holding.

An official acknowledged that most of the horses taken off the range exhibited fairly good body conditions, contrary to earlier reports that many were suffering from lack of water and forage due to overpopulation and drought.

Black Mountain Roundup, Part 2, Day 132

The operation began on March 9, a resource enforcement action that follows a wild burro removal in 2020Gather stats through July 18:

  • Burros captured: 303, up from 243 on Day 122
  • Capture goal: 500
  • Removal goal: Probably 500
  • Returned: 0
  • Deaths: 0
  • Shipped: 209, no change from Day 122

The cumulative total on the gather page is 306.

Foals represented 14.9% of the burros gathered.  Of the adults, 61.6% were male and 38.4% were female, not what you’d expect to find in a sample of n = 303 taken from a simple random process centered at 50% males / 50% females.

Do these results tell you anything useful about the herd at large?

There were 94 burros in the unaccounted-for category.

The incident is not open to public observation.

Supplemental statistics:

  • AML: 478
  • Pre-gather population: Unknown
  • Forage liberated to date: 1,818 AUMs per year
  • Water liberated to date: 1,515 gallons per day
  • Burros displaced from HMA by privately owned livestock: 1,222
  • True AML: 1,700
  • Excess animals before roundup: Unknown

RELATED: Black Mountain Roundup, Part 2, Day 122.

UPDATE: The limits of variation for males and females should be based on n = 258 adults, not n = 303.  The observed percentages are still outside the calculated limits with n = 258.  The formula for computing the limits can be found in this Wikipedia article.

Cibola-Trigo Roundup Over

Gather operations ended July 15 with 228 burros captured, 227 shipped and one death, according to figures at the gather page.

The goal was 200.

The gather page said 230 animals removed.

Foals represented 12.7% of the total.  Of the adults, 44.7% were male and 55.3% were female.  The number of unaccounted-for animals was zero.

The incident was not open to public observation.

Onaqui Roundup Over

Gather operations ended today with 435 horses captured, one death and one returned, according to figures at the gather page.

The goal was 400.

Foals accounted for 10.8% of the total.  Of the adults, 47.9% were male and 52.1% were female.  The number of unaccounted-for animals was zero.

The incident liberated 5,208 AUMs per year for other mandated uses of public lands.

RELATED: Onaqui Roundup Day 4.

UPDATE: The AUMs liberated will be reduced by the horses returned to the HMA, including those treated with contraceptives.  The final figure may be closer to 4,000 AUMs per year, assuming 100 horses returned.

Putting Price Tags on America’s Wild Horses and Burros

Comments on the 2018 EA for resource enforcement actions in the Onaqui Mountain HMA suggested that forage on public lands generates an economic benefit of about $100 per AUM per year.

If that’s true in other areas, a wild horse, who consumes 12 AUMs per year, represents an economic loss of $1,200 per year.

A wild burro, who devours six AUMs per year, represents a loss of $600 per year.

The AML for Twin Peaks HMA is 758 wild horses and 116 wild burros, for a total economic loss of $979,200 per year.

For simplicity, let’s assume the 27,000 animals allowed by plan on your public lands are horses only.  The economic loss is $32.4 million per year.

The current population of 95,000 represents a loss of $114 million per year.

As Archie D. Ryan of the DOI stated many years ago, “The wild horse consumes forage needed by domestic livestock.  They bring in no return and serve no useful purpose.”

Chincoteague Pony Auction Next Week

The herd will not be forced to swim across the channel this year but the mares and foals will be trailered to the carnival grounds after roundups and sorting on July 25 and 26, according to an announcement by the Chincoteague Volunteer Fire Company.

The foals will be auctioned and the mares returned to their home territory (Virginia side of Assateague Island).

The announcement did not say if any of the foals would rejoin the herd and provided no information on long-term trends in herd sizes, sex ratios and genetic diversity.

Onaqui Roundup Day 4

The incident began on July 14.  Gather stats through July 17:

  • Horses captured: 344
  • Capture goal: 400
  • Removal goal: 296
  • Returned: 1
  • Deaths: 1
  • Shipped: 342

One death occurred on Day 3, related to the roundup.

Foals accounted for 10.2% of the horses gathered.  Of the adults, 48.9% were male and 51.1% were female.

There were no unaccounted-for horses.

Some of the mares will be treated with contraceptives and returned to the HMA along with some of the stallions.

Gather operations will likely conclude in another day or two.

Supplemental statistics:

  • AML: 210
  • Pre-gather population: 500
  • Forage liberated to date: 4,116 AUMs per year
  • Water liberated to date: 3,430 gallons per day
  • Horses displaced from HMA by livestock: 1,300 (estimated)
  • True AML: 1,510 (estimated)
  • Excess animals before roundup: None

Status of Onaqui Allotments

The 2018 EA for resource enforcement actions in the HMA provided little information about livestock grazing, as noted by some of the commenters.

Table 1 in the Comment Report shows ten allotments that intersect the HMA, along with size, available AUMs and grazing seasons.

Unfortunately, the percentage of grazing land (or forage) falling inside the HMA was not provided, so a ‘Short End of Stick’ report is not possible.

All of the data in following table were taken from the Allotment Master report in RAS except the 2018 AUMs, which were sourced from Table 1.

Onaqui Allotment Data 07-16-21

The AUM figures in Table 1 for West Lookout Pass appear to be for the number of animals on the permit, not the amount of forage, per the Authorization Use report for the allotment.  The grazing seasons may also be incorrect, so the 2018 allocation was assumed to be the same as 2021 and that’s why the value is marked in red.

The HMA contains about 205,000 public acres according to the EA.  The allotments contain about 267,000 public acres, so some of them must extend beyond the HMA boundaries.  The map provided with the EA does not show their boundaries.

Six of the ten allotments do not meet standards for rangeland health.

Eighty six percent of the public acres in the allotments do not meet standards for rangeland health.

For every public acre in the Maintain category, there are six acres in the Improve category.

There is no category for blaming substandard conditions on wild horses.

Suppose that 80% of the permitted forage falls within the HMA, about 15,700 AUMs per year.

The horses allowed by plan receive about 2,500 AUMs per year, so livestock would be receiving six times more forage than the horses—on land set aside for the horses.

The HMA would be managed primarily for livestock.

The forage assigned to livestock would support an additional 1,300 wild horses, for a True AML of 1,510.

The pre-gather population was about 500, so there were no excess horses in the HMA and no justification for a roundup or fertility control program.

The 1,300 wild horses cheated out of a spot on their home range account for 2.6% of the 50,000 horses in off-range holding.  How many more HMAs would you have to look at to account for all of them?
