Black Mountain Roundup, Part 2, Day 175

The incident began on March 9, a resource enforcement action that follows a wild burro removal in 2020Gather stats through August 30:

  • Type: Planned
  • Method: Bait
  • Burros captured: 450, up from 369 on Day 156
  • Average daily take: 2.6
  • Capture goal: 500
  • Removal goal: 500
  • Returned: 0
  • Deaths: 0
  • Shipped: 368, up from 306 on Day 156

Foals represented 14.7% of the burros gathered.  Of the adults, 58.6% were male and 41.4% were female.

To date, 225 jacks and 159 jennies have been captured.  The observed percentages of males and females cannot be explained by a simple random process centered at 50% males / 50% females, with n = 384 adults.  The sex of the foals was not given.

The expected range of variation can be found with basic statistical formulas.

Day 175 ended with 82 unaccounted-for burros.

Other statistics:

  • AML: 478
  • Pre-gather population: Unknown
  • Forage liberated to date: 2,700 AUMs per year
  • Water liberated to date: 2,250 gallons per day
  • Forge assigned to livestock: 7,333 AUMs per year (estimated)
  • Burros displaced from HMA by livestock: 1,222
  • True AML: 1,700
