“of the total number of livestock and wild horses and/or burros known or authorized to graze within HMAs and their associated grazing allotments, 1.8 percent are wild horses, 0.4 percent are wild burros and the remaining 97.8 percent are livestock.”
We encourage all people interested in public lands issues to be sure to read the Animal Welfare Institute report (2012) Overview of the Management of Wild Horses & Burros. AWI presented this to the National Academy of Science. Although this report was issued in 2012, the issues are all current. This report gives an excellent overview of wild horse & burro issues and the mismanagement of the Bureau of Land Management’s Wild Horse & Burro Program. We will be pulling out a few excerpts for some articles, since this report counters all of the false information by sources at the recent National Wild Horse & Burro Advisory Board meeting, by the livestock grazing activists and in the media.
AUM is Animal Unit Month – The BLM has defined this as the amount of forage needed to sustain one cow and her calf, one horse, or five sheep or goats for a month. (AML is Appropriate Management Level)
Pages 145-149 of this AWI report indicate the following:
Figure National – 7
For the ten western states occupied by wild horses and/or burros, BLM data reveals that the total number of authorized AUMs for 2011… included actual AUM use of 8,297,403 for cattle, yearlings and domestic bison, 53,119 for domestic horses and burros, and 708,280 for domestic sheep and goats. The 2011 estimated combined population size for wild horses and burros within HMAs was 33,805, while the combined high AML for wild horses and burros was 26,576.
These figures correspond to AUMs of 31,537 (for the estimated population) and 25,225 (based on combined high AML). Consequently, the number of AUMs for livestock within the ten western states in which wild horses and/or burros are found are 287 times the AUMs based on estimated wild horse and burro population size and 359 times the AUMs for wild horses and burros based on high AML. It is worth noting that, in a number of instances, the permitted use AUMs designated by the BLM were well in excess of the active AUM level (amount of use that could be allowed); a discrepancy that could not be explained by a BLM official.
Figure National -8
According to the BLMs Rangeland Administration database (accessed in September 2012), a total of 4,565,208 livestock (i.e., cattle and yearlings, domestic bison, domestic sheep, domestic horses and burros, and goats) have be en grazed on the estimated 669
allotments found entirely or partially within HMA boundaries within the past BLM billing cycle. This equates to 4,286,252 permitted use AUMs. When adjusted to compensate for the percentage of each allotment found within or outside of HMA boundaries, the total number of stock grazed is 1,302,259, which correlates to 1,626,450 seasonal/annual permitted use AUMs. When compared to the combined high AML for wild horses and burros for 2012, which corresponds to 299,562 annual AUM s, total livestock AUMs on HMAs is 5.4 times higher than the AUMs for wild horses and burros.
This is only an estimate since livestock use is not consistent across an allotment. This is because the animals tend to utilize those portions of an allotment that are most suitable in regard to water, forage, shelter, and other requirements. For the purpose of this analysis, the number of AUMs and individual livestock obtained from various BLM data sets was multiplied by the percentage of the allotment found within each HMA. Due to the lack of equal distribution of livestock a cross an allotment, these figures may under-or over-estimate actual use.
Livestock authorization and stocking rates are not static, but frequently change over time as a consequence of rangeland condition, economics, environmental factors (such as prolonged drought), changes to allotment permit conditions, changes in the type of
livestock grazed, and other factors. For the ten states that harbor wild horses and burros, livestock AUMs are highly variable. For example, based on BLM data, total livestock AUMs were 9,708,638 in 1996, declining to 9,058,802 in 2011.
In sum, based on the BLM data referenced above, 1,302,259 livestock are authorized to graze within HMAs occupied by an
estimated 24,264 wild horses and 5,017 wild burros as of February 2012. Therefore, of the total number of livestock and wild horses and/or burros known or authorized to graze within HMAs and their associated grazing allotments, 1.8 percent are wild horses, 0.4 percent are wild burros and the remaining 97.8 percent are livestock. At the state, individual HMA, or HMA complex level, these
statistics differ. Regardless of the geographic scale of the analysis, however, the number of livestock grazing on HMAs is far in
excess of the number of wild horses and/or burros.
