Paisley Desert Roundup Day 8

The incident started on October 11.  Gather stats through October 18:

  • Horses captured: 596
  • Goal: 750
  • Deaths: 10
  • Returned: 0
  • Shipped: 330

Foals accounted for 21% of the total.  All of the deaths were attributed to pre-existing conditions.

The daily results yield 330 horses shipped but the cumulative total says 436.

Body condition scores are not known.

The imbalance is 256 horses.  Some of the gap may be due to the discrepancy in the horses shipped.  The contractor should be holding the remainder on site.

The operation will likely conclude this week.

Red Desert Roundup Day 9

The incident started on October 10.  Gather stats through October 18:

  • Horses captured: 598
  • Goal: 2,400
  • Deaths: 1
  • Returned: 90
  • Shipped: 339

No activity on Day 8 due to weather.  Foals accounted for 23.7% of the total.  The sex ratio of captured adults is approximately 45% males, 55% females.

The reports did not indicate the HMA(s) where the horses were captured or released.

Of the horses returned, 46 were “treated with fertility control.”  No details were given.

Body condition scores are not known.

The imbalance is 168 horses.  The contractor may be holding them on site.

The release of horses back to their home range may indicate the operation is finished in one area and will resume in another.  Five HMAs are affected.

Red Desert Roundup Day 7

The incident started on October 10.  Gather stats through October 16:

  • Horses captured: 477
  • Goal: 2,400
  • Deaths: 1
  • Returned: 24
  • Shipped: 212

No activity on Day 5 due to weather.  Foals accounted for 23% of the total.  One death occurred today, Day 7, but no details were provided.  It was classified as pre-existing.

The reports did not indicate the HMA(s) where the horses were captured.  No details were given for the horses returned. 

The imbalance is 240 horses.  The contractor may be holding them on site.

FREES Conference Last Week

A story by the Powell Tribune of Powell, WY says the Free Roaming Equids and Ecosystem Sustainability Network met last week in Cody to discuss wild horse overpopulation and its effects on wildlife and multiple use of public lands.

The meeting follows one held last year in Reno.

The group seeks healthy herds on healthy rangelands, according to the report, which means “achieve and maintain AMLs,” code words for “manage HMAs principally for cattle and sheep.”

Hypothesis Revisited, Again

The original statement went something like this: The number of wild horses and burros in off-range holding can be explained by the misappropriation of forage on just a few dozen HMAs.

How’s the theory holding up?  Twelve more areas have been considered since the last report, they appear in the sidebar on the right titled ‘Short End of Stick.’

Data from those posts have been added to the original list, starting with the Big Summit WHT and ending with the Lost Creek HMA.

Short End of Stick Recap 10-14-20-1

Some areas are managed for burros but the calculations are based on wild horses.  If you want to know the number of burros displaced from an area by privately owned livestock, multiply the horses denied by two.  Same for the AMLs.

For the areas considered so far, livestock receive about 84% of the authorized forage (excluding wildlife), with the balance going to horses.  The total number of horses displaced from their home range is 46,770.

If you prefer a mix, you could say 45,000 horses + 2 × 1,770 burros = 48,540 wild horses and burros displaced from their home range, which is roughly equal to the number of horses and burros in off-range holding.

The theory has been validated.

The true AML of 55,503 is six times higher than the current AML of 8,733, slightly more than predicted by the Rule of 5.

Imagine what the true AML would be for all HMAs and WHTs!

The problem is not too many horses or not enough contraceptives.  The problem is public-lands ranching.

Mullen Fire Creeping Toward Deerwood Ranch?

The ‘Albany bulge’ has broken out to the north, bringing the fire closer to the suspected location of the off-range pasture (area labeled Middle Creek in the following map).

Yesterday’s fact sheet said a fire line has been established in the Middle Creek area between the fire and Centennial.

Mullen Fire and Deerwood Ranch 10-13-20-1

The fire has burned 176,000 acres since September 17 and is now 30% contained.

An email asking about the location of the ranch was never answered.

Saylor Creek Roundup Over

A month ago Western Horse Watchers was informed that the operation had concluded and that a news release was forthcoming.

The daily reports ended on August 24, with 104 horses removed.  The goal was 81.

The HMA has been dethroned as the worst example of wild horse mismanagement in the ‘Short End of Stick’ series, replaced by Lost Creek, where the horses receive just four percent of the total authorized forage, instead of five percent at Saylor Creek.

Lost Creek Horses Get Short End of Stick

Helicopters will be flying over the Lost Creek HMA, one of five HMAs in the Red Desert Complex, any day now.  Their mission is to enforce the resource allocations of the Rawlins RMP.

The HMA covers 251,000 acres in central Wyoming and has an AML of 82.  The horses require 984 AUMs per year and the stocking rate allowed by plan is 0.3 wild horses per thousand acres.

What do these numbers tell you about the way the HMA is managed?  The fractional stocking rate may indicate large amounts of forage diverted to livestock.

The HMA intersects one allotment according to Map 2 in the Final EA for wild horse management actions in the Complex.  The allotment extends into the Antelope Hills HMA but the EA does not provide the percentage in each.

Western Horse Watchers estimates that it’s one part in Antelope Hills and five parts in Lost Creek, or 83% in Lost Creek.  The estimated size of the allotment is 251,000 ÷ .83 = 302,410 acres.  Both HMAs are 100% subject to permitted grazing.

Table 5 in the EA provides the grazing season and permitted AUMs.  Although cattle and sheep are allowed on the allotment, the calculations are based on cow/calf pairs only, for a direct comparison to wild horses.  The resource requirements of cow/calf pairs and wild horses are said to be equivalent.

Lost Creek HMA Calcs A-1

The forage available to livestock inside the HMA is .83 × 27,292 = 22,652 AUMs per year, assuming the resource is evenly distributed across the parcel.

The Cyclone Rim permittees would have to place 3,539 cow/calf pairs inside the HMA to graze off 22,652 AUMs in 6.4 months.  The stocking rate allowed by plan is 3,539 ÷ 251,000 × 1,000 = 14.1 cow/calf pairs per thousand acres.

These management indicators are compared in the following charts.

Lost Creek HMA Charts-1

The HMA is managed primarily for livestock, with the horses receiving just four percent of the total authorized forage (excluding wildlife).  The HMA doesn’t have a Herd Management Area Plan (HMAP) but if it did do you think you could revise it independently of the RMP?

The pre-gather population in the HMA, thought to be around 4X AML (per the news release for the Complex), would include 246 excess horses, so the need for a roundup, along with other population controls, is obvious.

However, the forage assigned to livestock would support an additional 1,888 horses, for a true AML of 1,970.  There are no excess horses in the HMA, the roundup is not needed and there is no justification for a fertility control program.
