Animal Unit Month: An Animal Unit Month (AUM) is the amount of forage required by one animal unit for one month. AUM is the amount of forage needed to sustain one cow and her calf, one horse, or five sheep or goats for a month.
It is worth noting that the current cost per AUM for a private profit grazing on public lands is $1.35 per animal unit month (AUM). This represents a decrease from the 2018 Federal grazing fee of $1.41 per AUM (less than the cost of one can of dog food, a single latte, a 5 lb bag of flour).
BLM has also begun a program they call “Outcome Based Grazing.” This system further subsidizes public land livestock if they do not make the money they expect. The fees are based on “outcome.”
Many permittees will argue that wild horses are out all year and their cows are not, blaming any degradation on wild horses. If your fridge only has so much food it doesn’t matter if you invite too many party guests for 15 minutes or 15 hours, what you have is all you have. The same thing applies to the amount of grass that grows (you should also understand some permittees on public lands do have year round permits).
We have added this paragraph here for sake of argument: In Nevada domestic livestock are allotted 2 million AUM (from what can be tracked in 2019 from available data on BLM website). Wild horses have what is called an Appropriate Management Level (AML) of 12,811 that translates to 153,732 AUMs. If wild horses were at 4 times AML the AUMs would equal 614,928. That number is still a fraction of what is allotted to domestic livestock.
Fast comparative stats from the statistics available online. The BLM has removed many pages, including those that track livestock, from the internet:

So what is destroying the range, wild horses or domestic livestock?
