Foal-Free Friday, Pesticides and Cherished Horses Edition

Everybody uses Raid to get rid of their cherished ants and roaches.

Treatment for Cherished Cockroaches 07-27-22

What do the advocates use on their cherished wild horses?

PZP, an EPA-registered pesticide, sometimes referred to as the Montana Solution.

Symptoms include barren mares, confused stallions, shrinking herds, abnormal sex ratios, injuries, infections, disruption of natural order and subordination to livestock.

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.

Thriving Ecological Balance-3

WHBAB Nominations Sought

An unofficial notice at the Federal Register, set to publish tomorrow, indicates vacancies in these categories for three-year terms:

  • Humane Advocacy
  • Livestock Management
  • Wildlife Management

The official notice will appear at this page.

In the original statute, the needs of wild horses and burros were to be balanced with those of wildlife, not privately owned livestock.

The Board has not met in a official capacity for over a year.

Triple B Roundup, Day 25

The incident began on July 17.  Gather stats through August 10:

  • Target: Horses
  • Type: Planned
  • Method: Helicopter
  • Category: Cruel and costly
  • Captured: 1,043, up from 867 on Day 23
  • Average daily take: 41.7
  • Capture goal: 1,900
  • Removal goal: 1,800
  • Returned: None
  • Deaths: 20, up from 17 on Day 23
  • Shipped: 926, up from 801 on Day 23

The figures above are based on the daily reports.

A mare died of a broken neck on Day 24.  A foal died on Day 25 of colic and a mare was put down because of a broken leg.

The death rate is 1.9%.

The capture total includes 371 stallions, 507 mares and 165 foals.

Youngsters represented 15.8% of the animals gathered.

Of the adults, 42.3% were male and 57.7% 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 given.

The location of the trap was not disclosed.

The Complex and surrounding lands are subject to permitted grazing.

A filly was put down on Day 9 because of a broken leg.  Two fillies were put down on Day 10 due to hernias and a mare was euthanized because of a missing eye.

The horse death rate is 3.1% and the burro death rate is 1.2%.

Of the adults, 44.6% were male and 55.4% were female.

The herd can’t be growing at a rate of 20% per year with a birth rate of 13% per year.

A better estimate would be 8% per year, assuming a death rate of 5% per year.

Land managers often use a growth rate of 20% per year to predict herd sizes and justify resource enforcement actions.

New Grants Available for Wild Horse and Burro Management

The program, started last year, has been extended and projects ranging from $1,000 to $50,000 are eligible, according to today’s news release.

Proposals need not have a theme of “off the range” but those will likely receive highest consideration.

A darting program in Eastern Oregon was cited as an example.

Like HMAPs, your project must align with the priorities and goals of the land-use plans.

Foal Rescued from Mud at Beatys Butte HMA

A WHB Specialist with the BLM Lakeview District pulled him out with a rope after his mom ran up to her truck then back to a ridge several times, according to a report by KTVL News of Medford, OR.

The incident could have been avoided by an aggressive darting program, which the advocates would be eager to provide, aided by safe and efficient helicopter roundups.

The HMA is in southern Oregon and lies within the Beaty Butte Allotment.

The AML is small relative to the available resources, with livestock receiving six times more forage than the horses.

The government collects around $25,000 per year in grazing fees from ranching activity inside the HMA while it spends about $2.9 million per year to care for the 1,583 horses displaced thereby.

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

Are the advocates protecting the horses or the ranchers?

Benedict interviewed two BLM public affairs officers and the BLM Northern California District monitoring coordinator.

“That’s one of our big challenges as an agency.  We have a multiple-use mission.  You know, herd management area is a multiple use area, it’s not managed primarily for horses.”

Problem identified.  Causes known.

Data quality is poor.  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.

A colt was put down on Day 12 due to a broken leg.  Two more horses were euthanized on Day 13 because of pre-existing conditions.

The horse death rate is 1.4%.

The horse total includes 559 stallions, 648 mares and 251 foals.

Youngsters represented 17.2% of the horses captured.

Of the adults, 46.3% were male and 53.7% 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 12 and 13 ranged from 4 to 5.

The trap is in the North Twin Peaks Home Range.

The HMA is subject to permitted grazing.
