“It is incredible that one should have to furnish any argument to bring about any laws to save the Mustang, but if there must be an argument let it be this: that of all the things that have played a part in the development of this country, except for man, the horse has played the most important and beneficial role. He portrays the West as all people like to think of it. He is the symbol of wild freedom to us all.”

-Velma B. Johnston, a.k.a. Wild Horse Annie (1959)



There is a battle going on in the United States of America that many people are unaware of. Perhaps they think it’s unimportant, that it doesn’t affect them. The battle to save America’s wild Mustangs isn’t just between soft-hearted horse-lovers and hard-working ranchers. It’s much more complex than that. And in the end… we could all lose.

First of all, I do not support the idea of ceasing all BLM management of wild Mustang herds because since ranching and urbanization has taken over the ranges, and since humans hunt Mustangs' natural predators, the Mustangs would eventually overpopulate, cause habitat degradation, and starve. I must say that in some places the Bureau of Land Management (BLM) helps to care for the wild Mustangs by rounding up herds in places where there's very little food and/or water, and by rounding up Mustangs that wander onto private land (land owned by people). Some people in the BLM sincerely want to protect the Mustangs. Many roundups go without incident; the Mustangs are herded off the range into the holding pens, vaccinated, freeze-branded, and then adopted by loving owners. The BLM has many different facilities, and many are perfectly fine and do help the Mustangs. In some places the BLM is a good thing.

But in most other areas, the BLM uses its authority to take advantage of the animals and the land in its care. Over the past nine years, 40% of the Mustang population has been removed by the BLM for no other reason than rancher and government greed. Alternative methods for managing Mustang populations are available (savethemustanghorses.blogspot.…), and yet the BLM does not use them to any significant extent. Roundup teams are paid roughly $350 for each horse they bring in (dead or alive), so the pilots often go to drastic measures to capture as many horses as possible during each gather. Entire herds of Mustangs (including newborn foals) are driven at breakneck speeds over land deemed too rough for vehicles. Mustangs and burros (wild donkeys) are injured during the roundups and many beyond recovery and must be euthanized. (savethemustanghorses.blogspot.… , savethemustanghorses.blogspot.…)

The BLM openly admits to holding approximately 50,000 Mustangs in captivity (roughly double than there are in the wild), and their finances are running out. It costs roughly $3,000 tax dollars to process a single wild horse for adoption, and hundreds are removed in a typical roundup. It costs around $100,000 every single day to feed the captive Mustangs. Many Mustangs in BLM corrals are in poorer condition than they were and would be in the wild, and some are starving. Almost no BLM facilities provide shelter for the horses held captive. The panicked herd stallions often fight each other in the small spaces, desperately trying to keep their mares together, therefore hurting themselves and others.
"I'm assured repeatedly [by BLM veterinarians] that these horses are cared for," said wild horse advocate Elyse Gardner. "So why does it seem that it is the public observers that continually need to bring so many overlooked injuries, illness or orphaned foals to the attention of the BLM?" Again, alternative methods for managing Mustang populations on the range (so that they need not be removed and held in captivity) are available (savethemustanghorses.blogspot.…), but the BLM does not use them to any significant extent. This shows extreme shortsightedness on the BLM's account. They are wasting enormous amounts of money and causing animals to suffer when less expensive, more humane methods are available.

While many Mustangs do find good homes with kind people, many are sold to irresponsible owners who want to "break a wild bronco". Such owners don’t know how to handle wild horses, and are often injured. If the Mustangs are not adopted or sold, they are rarely ever returned to the wild. The BLM holds unadopted/unsold Mustangs in taxpayer-funded corrals until they either die of old age, they are euthanized, or the BLM gains the right to slaughter them. I repeat: alternative methods for managing Mustang populations on the range (so that they need not be removed and held in captivity) are available (savethemustanghorses.blogspot.…), but the BLM does not use them to any significant extent. The BLM would rather these animals suffered a slow death rather than use alternative methods to manage them.

Recent discoveries made by the National Academy of Sciences (www8.nationalacademies.org/onp… , www.nap.edu/catalog/13511/usin…) has found that by removing so many wild horses in roundups, the BLM is actually causing population growth instead of reducing it. By lowering the population to such an unnaturally small number, the herds become smaller than the carrying limit of the lands (the limit of how many animals can graze on the land before food begins to run out).With so much extra space, the species springs back as it would after a natural disaster or plague. NAS studies show that Mustang populations have been increasing by around 10% to 15% each year. For the BLM to continue their current operation, they will have to remove more and more Mustangs each year, therefore causing increasing population growth, and so on. The answer is clearly not to step up roundups yet again, but to find alternative means by which to control the population and to prevent Mustangs from becoming problems on privately-owned land.

Studies show that nearly 85% of the Mustangs are below genetic viability, meaning that they are inbreeding. By removing Mustangs and their genetic information from the wild, the BLM is forcing the Mustangs to inbreed even more.

Even with the rapid population growth (and therefore rising cost of roundups) if things continue in this manner, in about 50 years there will be no free-roaming Mustangs left. Wildlife biologists estimate that the Mustang will be extinct in the wild before the end of the century. Time is running out for the American Mustang. Will we let them become like the Quagga and the Tarpan, pale ghosts of memory? Your air won’t be any cleaner, your water won’t be any clearer, and your food won’t be any more abundant with Mustangs extinct.

In 1900, over a million Mustangs ran free (lipizzaner-kgirl.deviantart.co…, www.horse-breeds.net/mustangs.… , academickids.com/encyclopedia/… , www.masterliness.com/a/Mustang…).) Now, less than 25,000 of them are left, and that number is steadily falling. Turning our backs is not the answer. We cannot leave Mustangs to their own devices, but we also cannot ignore the damage that the BLM is doing.

Do Mustangs Have Natural Predators?

Anti-Mustang Logic: Natural Predators
There is a common misconception that wild Mustangs have no natural predators. This couldn't be farther from the truth. Mustangs' predators include, but are not limited to, cougars (mountain lions), various species of bears (grizzlies, black bears), wolves, coyotes, etc. Unfortunately, all these predators are hunted by humans and many, such as bears and wolves, have been displaced by human development, thus they're prevented from doing their job efficiently.

 Let's look at each major North American wild horse predator in depth:


Wolves

Wolves have the potential to be Mustangs' chief predator. In Canada, Mustangs are frequently preyed on by wolves. They are pack hunters, and while they are individually too small to bring down anything other than a foal or an old sick adult, a pack of them can easily bring down a healthy adult, even if a few pack members are injured or killed in the process. They also naturally roam in the same areas that Mustangs do: Northwest plains and sometimes mountainous regions. Unfortunately, wolves in the U.S. have had their population and habitat dramatically reduced due to human development. Thus, wolf territories today generally do not overlap with wild horse territories, even though they used to. This is what the National Academy of Sciences has to say about wolves and wild horses:
    Wolves are quite capable of preying on equids. In southern Europe, equids constituted 6.2 percent of wolf diets (range, 0-24 percent) (Meriggi and Lovari, 1996). In Abruzzo National Park, Italy, horses constituted 70 percent of wolf diets; however, unguarded horses are commonly hobbled in that area to prevent long-range movements (Patalano and Lovari, 1993, cited in Meriggi and Lovari, 1996). In northwestern Spain, a population of free-ranging ponies is heavily preyed on by wolves (Lagos and Barcena, 2012). Foal survival rate was very low (0.41), and 76 percent of foal carcasses found were killed by wolves. Van Duyne et al. (2009) reported that wild Przewalski’s horse foals were killed by wolves in Hustai National Park, Mongolia, and cautioned that predation could influence translocation efforts. However, those horses are sufficiently vigilant to survive and reproduce, so perhaps they have not lost essential skills (King and Gurnell, 2012). Wolves in a multiprey system have been reported to prey on feral horses in Alberta, Canada. Webb (2009) reported that one of 36 kills by wolves included a feral horse. Webb (2009) located 192 ungulates that had been killed by wolves in 11 packs from 2003 to 2006. Some 7 percent were feral horses, and they made up 12 percent of the total biomass consumed (0.01 ± 0.02 feral horse/pack per day). Despite evidence that wolves prey on equids elsewhere, the committee was unable to identify any examples of wolf predation on free-ranging equids in the United States.
This is basically the same thing that I've said. Wolves are capable of hunting horses, even adult horses, but in the U.S., they do not live in many of their native habitats. Wild horses still live in those habitats, but wolves no longer do, thanks to human involvement. In essence, wild horses are having the same exact problem that deer are having. Whitetail deer are overpopulating because their natural predator, the wolf, has been displaced by humans. The gray wolf in North America is not endangered, but it can't do its job effectively.




Cougars / Pumas / Mountain Lions

Cougars alone kill about half of Mustang foals born every year and are currently Mustangs' chief natural predator in the U.S., although wolves would be more effective if they were allowed to do so. The reason cougars are not as effective as wolves is because cougar and wild horse habitats to not generally overlap. Cougars are called mountain lions for a reason: they live in the mountains (wow, didn't see that one coming!). Mustangs usually live on the plains and in desert areas. Some HMAs (Herd Management Areas) are in mountainous regions, and in those places, cougars do a pretty good job of keeping the wild horse population in check. Cougars enjoy horsemeat so much that they will often focus on hunting mainly horses to the near exclusion of other prey animals. Unfortunately, because cougars usually don't live on the open plains or in the desert, those Mustangs are rarely preyed on by cougars. The most common desert predator that poses any sort of threat to wild horses is the coyote, which I will cover later. Wolves live and hunt in open plains, but they've been pushed out of Mustang plains by human development (as I mentioned earlier). This is what the National Academy of Sciences has to say about cougars and wild horses:
    Most predation on free-ranging equids in North America has been attributed to mountain lions. That has been reported by Robinette et al. (1959) and Ashman et al. (1983). Berger (1983c) cited an unpublished report of 21 cases of mountain lion predation on free-ranging horses in the Great Basin; those deaths spanned more than 20 years and had negligible effects on population growth. Feral (but not free-ranging) horses constituted 11 percent of mountain lion diets in Alberta (Knopff and Boyce, 2009). Horses constituted 10-13 percent of adult male lion diets, but female lion diets were almost devoid of horses (Knopff et al., 2010). Overall, mountain lion predation on free-ranging equids in North America is, with few exceptions, considered uncommon (Berger, 1986).
    One of the exceptions is the free-ranging horse population on the central California-Nevada border. Turner et al. (1992) examined foal survival rates in the area (the Montgomery Pass Wild Horse Territory managed by the U.S. Forest Service) because there was a ban on mountain lion hunting in California and low hunting pressure in Nevada that led to a high density of mountain lions. The study was conducted from May 1986 to July 1991 by examining the horse and mountain lion populations and documenting deaths of horses. The average annual cohort of foals over the 5 years was 32. The annual survival rates were calculated for foals (0.27), yearlings (0.95), and adults (0.96). From 1987 to 1990, 48 foals were lost; 58 percent were located as carcasses and 82 percent of those were killed by mountain lions. The authors concluded that mountain lion predation had a substantial effect on the demography of that free-ranging horse population. The study was continued, and Turner and Morrison (2001) used 11 years of data (1987-1997) to examine again the influence of mountain lions on the horse population in Montgomery Pass Wild Horse Territory. Their results supported the earlier work of Turner et al. (1992): mountain lions were responsible for the deaths of 45 percent of the foals that were born. Mountain lion predation was also hypothesized as a major factor in limiting horse population growth in an area of southern Nevada where they use high-elevation forested habitats in summer (Greger and Romney, 1999). Those habitats are excellent for mountain lions because of their broken topography.
   
By and large, research that has addressed the question of predation on free-ranging equids in North America has been limited to anecdotal observations and a few published papers, but at the time of the committee’s review, studies at the University of Nevada, Reno, that should provide more quantitative data were under way. The work in several mountain ranges of western Nevada was examining predation by mountain lions in multi prey systems in which free-ranging horses had various densities. Diet data were being obtained by using information from GPS-collared mountain lions to investigate predation events; more than 700 predation events had been investigated as of June 2012. Ten of 13 collared mountain lions that had access to free-ranging horses regularly consumed horses as prey. Horses were documented to have been consumed as prey by collared mountain lions in eight mountain ranges throughout the study area in western Nevada (Virginia, Pah Rah, Fox, Lake, Wassuk, and Excelsior ranges and Virginia and Smoke Creek Mountains). Preliminary data suggest that in that study area, where free-ranging horses are available as prey, more than 50 percent of the diet of collared mountain lions is made up of horses when diet data on individual mountain lions are pooled. Preliminary results suggest that mountain lions in that multiprey system are generalists at the population level but that some diet specialization occurs at the individual level: some lions select for deer where horses are more abundant, and some select for horses to the near exclusion of other prey items where mule deer, bighorn sheep, and domestic animals are present. There is also some evidence that the magnitude of predation on horses by mountain lions may be related to the density of free-ranging horses, greater predation on horses occurring where densities of horses are higher (Andreasen, 2012).
    The potential for mountain lions to affect the sizes of populations of free-ranging horses in North America is limited by the fact that most HMAs are in areas that have few mountain lions. The ranges of mountain lions tend to be concentrated in forested areas and at higher elevations (Kertson et al., 2011) and in areas that have mountainous or otherwise broken topography with limited viewsheds. In contrast, many horse populations favor habitats that have more extensive viewsheds. Mountain lions are ambush predators and require habitats that provide opportunities for stalking or finding prey without being seen. Other predators, such as wolves, are more cursorial—capable of pursuing prey across open habitats.
    That a large predator, when abundant, can substantially influence the dynamics of free-ranging horses is not surprising inasmuch as black bears (Zager and Beecham, 2006), mountain lions (Wehausen, 1996), and other predators (Ballard et al., 2001; Boertje et al., 2010) have exerted strong influences on ungulate populations. However, the influence of predation on horses in the western United States is considerably limited by a lack of habitat overlap both with mountain lions and with wolves. Another constraint is that among free-ranging horse populations, foals are the usual prey, and predation on adults has rarely been documented until the recent studies in Nevada. Population size is not affected as much by foal survival as it is by adult survival (Eberhardt et al., 1982), and foal survival is strongly affected by other variables (such as weather).



Bears

Bears are more than capable of killing an adult horse...if they can catch it. A single bear has a good chance of bringing down even a healthy horse, but the problem here is that horses are generally too fast for bears to catch. Again, wolves are the best candidate, seeing as they can chase a horse(s) and run it down. However, if a bear is lucky enough to catch a wild horse unawares, the bear has a very good chance of having a meal.



Coyotes

Coyotes typically prey on young or very sick horses. They share territory with Mustangs. Unfortunately, they aren't big enough to take on a healthy adult, unless they hunt in a very, very large pack, which isn't likely. Coyotes are not a main natural predator of Mustangs, although a pack of them could kill a foal or a very weak adult.









More information in the links below! This information is so basic that most of what I could find were websites aimed at tiny school children. Don't take it personally. It just goes to show how silly anti-Mustang people are that they actually need to be reminded of this stuff.
