  • BLM – Wild Horses & False-Narratives

    America has been Bamboozled by Government Narratives

    John Cox, M.A. C/M

    What I have done here, is cutting all the red tape of interpretation, and getting to the point. Comments by a well respected individual within our community, and directly from him — Mr. Rose MacPhee.

    The question is — Are Wild Horses Invasive, or are they Indigenous? Which brings about more questions, Does the BLM have a Right to Misinform the General American Public, about Wild Horses, in order to develop stronger ties with their Special Interest Groups, in this situation and directly involved, Ranchers that hold Public Lands Grazing Permits.

    What I have found, is the Bureau of Lands Management, is passing-off previous Research, that were indeed trying to establish the Hypothesis that Wild Horses disappeared 10,000 years ago, problem is, none of these Hypothesis generated research papers, directly connected / accepted by Peer Review confirmation. What this means, frankly, is there is no evidence to show, other than what they describe as an Absence of Wild Horses, from opinions of what could be . . .

    Now we discover, the Pleistocene Era not as destructive toward Wildlife as we assumed it was — in particular within the PNW (Pacific Northwest), and what Peer-Reviewed Research confirms as Island Tropical Zones of life, grasses, and healthy forests of Conifer, throughout the Pleistocene Era (more on this in future articles).

    I leave you with a short discussion, from Mr. MacPhee, during the forum (a short discussion, yes, but very affirmative, and truthful, as well as credible) — and the transcript, from their conversation.

    It is time for all to open our eyes to a reality, and to understand, one more brick in the wall, so to speak, that the Wild Horses are, and always have been Indigenous in America. The BLM et al., knowing lied, redirecting this conversation via False-Narratives, to favor Ranching on Our Nations Public Lands — knowingly, that cattle, a non-indigenous species in America, very destructive to our lands. Make no doubt, we have a lot more to say —

    “MANAGED TO EXTINCTION?

    A 40th Anniversary Legal Forum assessing the

    1971 Wild Free-Roaming Horses & Burros Act

    TRANSCRIPT: ROSS MACPHEE, Curator, Division of Vertebrate Zoology, American Museum of Natural History (AMNH)

    Introduction

    My comments refer not to the 1971 congressional act, which other panel participants will speak about, but instead to Executive Order 13112, released on February 3, 1999. In a number of ways this EO is very relevant to everything that we’re going to talk about tonight. This is, in effect, the federal government’s statement regarding what an invasive species is and how an invasive species can be recognized. It has been used as one basis for the BLM’s policy on wild horses because—in the BLM’s view—it offers grounds on which these horses can be considered invasive rather than native.

    The EO contains a number of definitions; I will review only a few:

    “The purpose of this order is to prevent the introduction of invasive species and provide for their control to minimize the economic and ecological and human health impacts that invasive species have caused.”

    According to the definitions in the order (as revised by the “2008-12 report” of the National Invasive Species Council and its precursor body, set up under sec. 5c of EO) an invasive species is: “a species that is non-native to the ecosystem under consideration and whose introduction into a particular ecosystem causes or is likely to cause economic or environmental harm or harm to human health.“

    By contrast, a native species means, with respect to a particular ecosystem, “a species, other than as a result of introduction, historically occurred or currently occurs in that ecosystem.”

    Now, why is any of this relevant to the issue of wild horses and burros?

    According to the publicly accessible BLM website, which is meant to be read by any citizen and presumably therefore unquestionably accurate, there are a number of “myths and facts” about WH&B.

    Among these is the following: (italicized content from BLM website)

    Myth #11: Wild horses are native to the United States

    Fact: This claim is false.

    American wild horses are descended from domestic horses, some of which were brought over by European explorers in the late 15th and 16th centuries, plus others along that were imported from Europe and were released or escaped captivity in modern times.

    Further, according to the BLM, “these horses have adapted successfully to the Western range, but biologically they did not evolve on the North American continent. The disappearance of the horse from the Western Hemisphere for 10,000 years supports the position that today’s wild horses cannot be considered ‘native’ in any meaningful historical sense.”

    Now I put it to you that every clause, every sentence about the foreigness of horses in the passages I just read is palpably wrong, demonstrably wrong, not only according to people like me but also to anybody who has any intimate understanding of the history of horses on this continent.  

    Now let me just put this in a nutshell. The family Equidae evolved on this continent; it is as American as anything you could possibly imagine. That was 55 million years ago. Progressive evolution occurred thereafter, eventually culminating 1.8 million years ago when a horse very like modern horses evolved. With a very high statistical probability, domestic horses, The Horse, evolved from that precursor and spread throughout North America and then across land bridges to Eurasia and South America.  

    Scientifically, the BLM’s comment that The Horse did not biologically evolve on the North American continent is wrong, and therefore the additional comments about The Horse being foreign to the Western ecosystem is completely irrelevant.  

    It is additionally irrelevant to say that today’s ecosystem in which today’s mustangs and feral horses survive is somehow completely different from what was here 10,000 years ago. That is simply not true.  The conditions that characterize this ecosystem that you think of as normal, the one you are in now, in this present warm period that’s getting warmer all the time, have come and gone repeatedly throughout the past 2.4 million years. This period encompasses the Ice Ages, during which warmer and colder periods oscillated with substantial frequency.

    To say that there is a “Western ecosystem” that is in place now that is completely different from the one in existence 10,000 or more years ago is a red herring. Of course it is different! And it was different from the one at 20,000, and all the way back as far as you want to go.

    Yet virtually all of the species that anyone would regard as “native” to North America today went through these very same alternating warm and cold periods with no trouble because they were in fact adapted to the roller-coaster climate system that has prevailed here throughout the Pleistocene.

    So horses are of course adapted to this place, because this place has been a roller coaster with respect to its ecosystem over this whole period.  So if nothing else happens out of this discussion, what I want you to take home is the idea that scientifically, the idea that horses are an invasive species is utterly wrong.  Thank you.

    Ross MacPhee (Panel discussion):

    A native species by definition cannot be invasive. So rather than start with competing interests as between humans, horses, and commerce, the first question I want to ask is what would that Western ecosystem have been without people, in particular white people, during the last 500 years?  There would have been enormous herds of bison, for one thing. These same family ranchers who have been competing with horses would now be competing with bison if they were still here in large numbers. Would they be managed in the same way we allow horses to be managed? I would say no, because most people regard bison as a native species even though it has only occupied North America for the past 125,000 years. But horses are seen in a different category: they are invasive species, like zebra mussels or Med fly; and therefore they have no rights.

    What we are in now is a novel ecosystem; we’ve been altering it at an incredible rate for a very long period of time. Thanks to our presence and the modifications we have introduced over centuries, in a sense it is not what it was before. OK, under BLM understanding does that mean that every species that is native here now should be disenfranchised . . . ?

    You can see how these wrongly-formulated, supposedly scientific interpretations keep biting their tails. And my point here is let’s start with something that can be fixed – because lots of things will flow from that. If it can be fixed that the horse is a native species, then it has to be treated like wolves, like bison, like whooping cranes, like all of the things that we consider to be a part of the American landscape, long before we came along.

    That will have an impact. There will be certain things that are no longer possible to do, because you can’t treat native species as we treat horses nowadays. There are competing rights as between horses and people, I accept that. But there are rights that should accrue to horses as native species that they don’t have at the moment. In allocating and weighing rights, all sides need to be at the table, sitting at the same height. At present, The Horse is down here (points down low) and everybody else with different kinds of rights are up here (points up).  Now that, to me, is the fundamental problem. . .”

  • WILD HORSE POPULATION GROWTH

    Kathleen Gregg Environmental Researcher

    Lisa LeBlanc Environmental Researcher

    Jesica Johnston Environmental Scientist

    April 25, 2014

    INTRODUCTION

    The recent National Academy of Science (NAS) report on the Wild Horse and Burro Program determined that the Bureau of Land Management (BLM) has no evidence of excess wild horses and burros; because the BLM has failed to use scientifically sound methods to estimate the populations (NAS, 2013). The NAS cited two chief criticisms of the Wild Horse and Burro Program: unsubstantiated population estimates in herd management areas (HMA), and management decisions that are not based in science (NAS, 2013). 

    Effective wild horse and burro management is dependent on accurate population counts and defensible assumptions. The Bureau of Land Management (BLM) routinely uses the assumption that wild horse and burro herds increase annually at an average rate of 20%.  However, our review of available scientific literature combined with an analysis of BLM data for 5,859 wild horses found that approximately 50% of the foals survived to the age of 1 year, which indicates a 10% population growth rate based on yearling survival rates.

    METHODS AND DATA

    The data and analysis is based on the BLM’s wild horse and burro removal and processing documents acquired under the Freedom of Information Act. The data sets were evaluated separately, and then combined to total 5,859 wild horses, captured, aged, and branded by BLM.  This data is the basis for the analysis in this report and the accompanying chart in table 1 below.

    Burro data was also calculated for foal and yearling survival. That data indicated a 7% population growth rate for burros based on yearling survival, but that data is not included here as burros are not present in all of the HMAs.

    The data was collected from 4 herds captured by BLM in Nevada and California in 2010 and 2011. The data below in table 1 shows the individual herds and accumulated age structure data which supports the overall conclusion. Wild horse foals and yearlings were tallied for population increases and in all four samples, recorded a combined foaling rate of less than 20%, but only half or 50% survived to the age of 1 year (see table 1 below).

    Table 1 Age Structure Yearling Survival Rate

    DISCUSSION

    This research does not include or reflect the additional adult mortality rates due to the complexity of population dynamics, but does raise serious questions about the validity of the BLM’s assumed 20% annual herd population growth rate. Furthermore, the BLMs assumption fails to consider that wild horse populations are dynamic due to isolation and have varied rates of reproduction and survival due to changing climates, forage, competition, disturbance and environmental conditions.  All these are factors that can lead to varied herd growth rates and each herd should be evaluated separately.

    This research paper is supported by previous studies using age structure data completed by Michael L. Wolfe, Jr. in 1980 titled “Feral Horse Demography: A Preliminary Report”. Mr. Wolfe cited observations in 12 HMAs, over a period of 2 to 5 years, and covered a much broader range over six Western states. He questioned the annual rate increase of 20%, and found that first-year survival rates to range between 50% and 70% (Wolfe, 1980).

    Other supporting research includes The National Academy of Science National Wild and Free-Roaming Horse and Burro report of 1982, which states, “…several biases in the (BLM) census data, cited or calculated rates of increase based on a number of published values for reproduction and survival rates, as well as sex and age ratios, and concluded annual rates of increase of ten percent or less” (NAS, 1982).

    The NAS 2013 report also used age structure data to estimate population growth. However, the report used foaling rates to draw conclusions about the population growth; rather than first year survival rates (NAS, pg.51-52 2013). This and other studies challenge the assumption that the 20% foaling rate provides an adequate measure of population growth.

    The BLM bases their management decisions on environmental assessments that cite inflated population estimates. As shown in this study and previous research, the BLM’s assumption of a 20% annual wild horse population growth rate is not based in science; leading to unsubstantiated population estimates with no evidence of excess wild horses.
