Triple B Roundup, Day 30

The incident began on July 17.  Gather stats through August 15:

  • Target: Horses

Helicopters did not fly on Days 28 to 30.  No explanation was given.

Youngsters represented 16.1% of the animals gathered.

Of the adults, 42.1% were male and 57.9% were female.

The herd can’t be growing at a rate of 20% per year with a birth rate of 16% per year.

A better estimate would be 11% per year, assuming a death rate of 5% per year.

The observed percentages of stallions and mares cannot be attributed to a simple random process centered at 50% males / 50% females.

Abnormal sex ratios are often found in herds subject to the Montana Solution but not double-digit birth rates.

Body condition scores were not provided.

The location of the trap was not disclosed.

Chemehuevi Nuisance Roundup in the Works?

A new project has been created in ePlanning and a Categorical Exclusion has been posted with no opportunities for public comment.

The document includes a signed Decision Memorandum on page 17, suggesting the process is now in the appeal stage.

The Proposed Action would utilize bait traps to capture and remove approximately 275 nuisance burros outside the Chemehuevi HA and HMA, on tribal lands within the Chemehuevi Indian Reservation, Colorado River Indian Tribe lands and Metropolitan Water District private property.

The HMA occupies about one third of the HA, with 108 burros allowed by plan.

The maps in Attachment 1 show the arrangement.

The current population is thought to be 764, with burros drifting into populated areas causing disturbance within the Chemehuevi Indian Reservation, creating hazardous conditions to the public near highways and public health and safety issues on private property, according to the discussion in Section A of the CX.

A Chemehuevi roundup does not appear in the latest schedule.

Permitted Grazing a Wise Use of Public Lands?

The advocates seems to be saying “Yes,” as they are determined to make privately owned livestock the primary consumers of resources in areas set aside for horses and burros.

The BLM collects $936,600 per year in grazing fees from ranching activity that displaces the 58,000 wild horses in off-range holding, while it spends around $60 million per year to care for them.  But you’re not supposed to know that.

RELATED: Rorschach Test for Advocates.

Frauds of the Wild Horse World 07-08-22

Livestock Outnumber Horses and Burros on Public Lands?

Refer to this handout for proposed changes to livestock grazing regulations.

The BLM authorizes around twelve million AUMs per year for livestock (page 11) on 155 million acres (page 1), enough to support one million wild horses, or, if you prefer, one million cow/calf pairs on a 12-month grazing season.

The agency also authorizes about 27,000 wild horses and burros on 27 million acres.

Assume it’s all horses.

The resource requirements of wild horses are said to be equivalent to those of cow/calf pairs, according to this 2016 infographic.

Livestock Grazing Infographic 08-14-22

Livestock can access 5.7 times more land than the horses, but the number of animals allowed by plan is 37 times higher.

Land is always more productive, from a resource viewpoint, and has a much higher carrying capacity, when it’s designated for livestock.  In some cases, it’s the same land.

The stocking rate allowed by plan in HMAs is one wild horse per thousand acres but the target rate in allotments is 6.5 wild horses (or cow/calf pairs) per thousand acres.

If there was no dietary overlap, livestock would not thrive inside the HMAs and the horses would die beyond them.

Neither is true.

The BLM will collect $936,600 in grazing fees from ranching activity that displaces the 58,000 wild horses in off-range holding, while it spends around $60 million per year to care for them.

Would you say that permitted grazing is a wise use of the public lands?

Blue Wing Roundup Ends, Again

The statement at the gather page was not correct.  The incident concluded on August 12, with 228 horses captured, 214 shipped, four dead and none released.

The number of unaccounted-for animals was ten.

The operation also took 805 burros off the land, with 794 shipped, ten dead and none released, leaving one unaccounted-for animal.

These figures are based on the daily reports, not the totals posted by the BLM.

The capture and removal goals were identical, 200 horses and 800 burros, suggesting that no animals will be treated with fertility control and returned to the Complex.

Foals represented 11.0% of the horses gathered and 7.7% of the burros, considerably less than the 25% needed to produce growth rates of 20% per year.

The roundup proceeded as planned, despite two legal complaints by the advocates, one involving HMAPs and the other involving rights protected by the First Amendment.

RTF Applauds BLM Grants, If They Involve Fertility Control

The ranching advocacy group and signatory to the ill-advised Path Forward said today in a news release that the agency needs to overhaul the way that wild horse herds are managed on our public lands, not the way that public lands are managed.

Consider this example from the Warm Springs HMA in Oregon.  The calculations were discussed in a previous post.

Warm Springs AUM Summary-1

These figures signify nothing to the advocates because they are innumerate.

The BLM will collect $26,179 per year in grazing fees from ranching activity inside the HMA, while it spends $2,949,200 per year to care for the 1,616 wild horses displaced thereby.

The problem is permitted grazing but the advocates want to get rid of the horses!

  • The AML is small relative to the available resources
  • The horses receive a small fraction of the authorized forage
  • The HMA is managed primarily for livestock

That’s what Return to Freedom and its supporters are trying to protect.

  • Burro deaths: None
  • Horses shipped: 1,905, up from 1,657 on Day 16
  • Burros shipped: 38, no change from Day 16

The figures above are based on the daily reports.  They may differ from the totals at the gather page.

No burros have been taken since Day 8.

The gather and removal targets changed on August 8 as noted above.

One burro and 22 horses have been returned to the HMA but this was not documented in the daily reports.

Three horses were euthanized on Day 18 due to pre-existing conditions and two foals died in temporary holding, causes unknown.

The horse death rate is 1.3%.

The horse total includes 817 stallions, 942 mares and 350 foals.

Youngsters represented 16.6% of the horses captured.

Of the adults, 46.4% were male and 53.6% were female.

The herd can’t be growing at a rate of 20% per year with a birth rate of 17% per year.

A better estimate would be 12% per year, assuming a death rate of 5% per year.

Body condition scores on Days 17 and 18 ranged from 4 to 5.

The trap is in the North Twin Peaks Home Range.

The HMA is subject to permitted grazing.
