Despite taxpayer funding, incompetent implementation by the Montana Dept. of Livestock, and lack of rancher compliance with their own rules, the state’s brucellosis free status remains intact.

NOT ENFORCING THE RULES

The Department of Livestock is not enforcing the required Designated Surveillance Area rules.

  • The Department of Livestock’s “current compliance and oversight process does not directly monitor” and verify whether brucellosis testing is occurring for movements of livestock out of the Designated Surveillance Area. (18)
  • Of 225 movements of livestock involving at least 10,000 head of livestock out of the Designated Surveillance Area, only 40 movements documented “health requirements” though this information does not disclose the required brucellosis test. (17)
  • The Department of Livestock is not following up on rancher noncompliance for brucellosis testing and consistently enforcing its Designated Surveillance Area rules. (17)
  • The Department of Livestock is “not documenting herd management risk assessments . . . including the basis for exceptions or variances to DSA brucellosis testing requirements.” (20)
  • In 50 audited samples, “there were no documented risk assessments attached to or explained within the plans.” (20)
  • The Department of Livestock is not annually reviewing the 160 herd management plans in place. (19, 20)
  • The Department of Livestock is not documenting its basis for providing variances or exemptions for ranchers from brucellosis testing requirements. (21)
  • “Allowing certain DSA livestock to not be subject to brucellosis testing requirements creates risks.” (21)

 

NOT FOLLOWING THE RULES

Cattle ranchers in the Designated Surveillance Area are not complying with the 5% brucellosis testing requirement.

  • 107 cattle ranchers were noncompliant in 2015. (17)
  • The Department of Livestock “could not demonstrate consistent enforcement actions” and did not conduct “consistent follow-up on cases of apparent noncompliance.” (17)

 

NOT FISCALLY RESPONSIBLE

Montana is paying higher rates than Idaho and Wyoming to test for brucellosis and vaccinate cattle.

  • Montana compensates ranchers $2 per head, in addition to covering veterinarian costs for vaccinating cattle. (22)

The Montana Department of Livestock is making reimbursements to ranchers without knowing the costs being reimbursed.

  • Conclusion: “Audit work was not able to determine what direct costs the reimbursements to producers are intended to offset.” (22, 25)

The Montana Department of Livestock is making reimbursements for vaccinating cattle without proper documentation or the required approval for reimbursements over $5,000.

  • Approximately $40,000 in payments were made to large cattle ranchers without the required sign-off of the administrator. (26)
    73% of adult vaccination payments “did not have full supporting documentation, such as an official record of all vaccinations being reimbursed.” (25)
  • The Department of Livestock made $24,000 in payments for which it “did not request or maintain supporting documentation.” (26)

 

ELK TARGETED

Montana Fish, Wildlife & Parks is targeting wild elk in brucellosis risk management actions.

  • Since 2013, Montana Fish, Wildlife & Parks carried out 26 brucellosis risk management actions for elk. (34)
  • 53% of elk in Paradise Valley have been exposed to brucellosis. (12)
  • Between 3% and 53% of elk have been exposed to brucellosis in the hunting districts encompassed by the Designated Surveillance Area boundary. (33)
  • The majority of the funding for Fish, Wildlife & Parks brucellosis management comes from federal revenue transferred from the Dept. of Livestock. Fish, Wildlife & Parks is also using general license and Pittman-Robertson funding. (35)
  • Fish, Wildlife & Park’s assistance to landowners is provided without having defined eligibility criteria for landowners receiving such assistance. (35)
  • “35 percent of the brucellosis response actions were carried out on land that either allowed no public hunting access or limited access to public hunters.” (36)
  • “31 percent of the management actions lacked associated documentation of public hunting access status of the land the action was carried out on.” (36)

 

BUFFALO TARGETED

In lethally removing wild bison, the Montana Department of Livestock is not following adaptive management.

  • “However, in 2015, DOL personnel conducted two lethal removals of bison. . . Though these bison were outside of the IBMP management zones, documentation of these incidents did not establish that the bison poses an imminent threat of coming into contact with livestock that necessitated lethal removal of the bison, nor were there initial attempts to haze the bison from the conflict area. The IBMP Adaptive Management Plan specifies that bison in conflict areas are initially to be hazed from the area. DOL lethally removed bison that may not have represented a brucellosis threat, and operational documentation did not provide a clear rationale as to why lethal removal was necessary in these cases.” (31)
  • “Neither DOL management nor the associated documentation made it clear why the IBMP adaptive management guidelines were not followed in these particular cases.” (31)
  • The legislative audit recommended the Department of Livestock follow the “Interagency Bison Management Plan adaptive management guidelines when lethally removing bison” and clearly document the need for lethal removals. (S-1, S-2)

 

RULES PROTECT MONTANA’S STATUS

Despite six incidences of brucellosis infection blamed on wild elk, the Designated Surveillance Area rule maintains Montana’s brucellosis Class Free status.

  • “The regulations that comprise the DSA program impact approximately 78,500 head of livestock that graze or live within the DSA boundary on either a seasonal or a year-round basis, and this number represents approximately 5.2 percent of the livestock in the state as a whole, according to Department of Livestock records.” (7)
  • Montana is maintaining its brucellosis Class Free status despite six incidents of brucellosis infections in livestock since 2010. (5, 9)

The U.S. Dept. of Agriculture Animal and Plant Health Inspection Service is paying for Montana Fish, Wildlife & Parks brucellosis management actions targeting wild elk in Montana. The taxpayer funding flows through the Montana Dept. of Livestock – from the same pot of money the livestock agency uses to destroy wild buffalo in the state.

According to Dr. Joe Templeton of Texas A& M University’s Department of Veterinary Pathobiology, in remarks made to the Greater Yellowstone Interagency Brucellosis Committee (GYIBC) on May 21, 1998:

buffalo hybrid beefalo genetics chart"The so-called random shooting at the Montana borders is actually eliminating or depleting entire maternal lineages, therefore this action will cause an irreversible crippling of the gene pool. Continued removal of genetic lineages will change the genetic makeup of the herd, thus it will not represent the animal of 1910 or earlier. It would be a travesty to have people look back and say we were 'idiots' for not understanding the gene pool."

and

"Bison have developed a natural resistance, genetically, as long as they have enough to eat, limited stress, and are not consumed by other diseases. There is no magic bullet in wildlife disease, therefore management is important. Vaccines are one management tool and one component, but genetic structure is necessary for future management. Every animal which is removed from the breeding population can no longer contribute to the genetic variability of the herd."

Dr. Templeton’s statements about lineages and the gene pool of genus “Bison Bison” are directly relevant to our efforts to have threatened or endangered status of this long beleaguered species formally recognized with an Endangered Species Act listing. While he does not explicitly state the reason for his concern about “Every animal which is removed from the breeding population...”, the implication is that there are so few wild buffalo in existence that EVERY SINGLE ANIMAL is a genetic necessity if we are to ensure this species’ survival! That is why we fight so hard, and that is why we need your help. Okay, back to the science...

Population Explanation

The Yellowstone bison population currently exists as an isolated "meta-population." This is what population geneticists call a population which consists of several small groups, referred to as "subpopulations," which interact with each other to some degree. Each subpopulation within the meta-population can have its own distinctive genetic structure which distinguishes it from the others. If individuals remain in their own respective subpopulation and do not mate with outside individuals, certain genes within the subpopulation become fixed.

In other words, in isolation they lose alternative genes normally obtained through random mating and selection. This eventually leads to a loss of genetic variation in the subpopulation. If there is inter-sub-herd migration, and mating of individuals at a moderate rate between the subpopulations, then genetic variation can be maintained throughout the entire meta-population. This is most ideal, as long as the genetic exchange never includes hybridized animals.

Variety is the (Genetic) Spice of Life

Genetic variation is critical to the long-term survival and evolutionary potential for any species or population. It can become decreased through isolation, inbreeding, and strong selective pressures such as environmental changes, habitat loss, diseases, or extensive mortality.

Loss of genetic variability removes genes from the population that could enable certain individuals to survive a major event, reproduce, and pass on their genetic material to the next generation. Low genetic variability within an individual or population greatly reduces the ability to respond to a major disease event or adapt to changing environmental conditions. Ultimately, this will drive them into an extinction vortex from which they might not recover, and “beefalo” hybridization is just another huge risk factor. Genetic degradation or loss of variability has already occurred in many wild species which have disappeared from the globe.

“Must” we ever “Cull?”

The current "clear cut" style of removing bison from the Gardiner area poses a grave risk to the genetic integrity of the entire Yellowstone bison herd for a number of reasons. Perhaps the most tragic part is that the northern herd subpopulation was nearly wiped out in 1996/97.

The current herd probably consists of remnant individuals and migrants from other adjacent Yellowstone subpopulations. Removal of a large number of individuals from only one subpopulation within a single region poses the risk of permanent loss of entire lineages—a potentially irreplaceable loss to the species.

If population control were ever truly necessary (which we, for the record: doubt severely), then a scattered, random removal of individuals would probably be more conducive to maintaining genetic diversity. However, the carrying capacity for bison in the Greater Yellowstone ecosystem has not been accurately established.

“Ideal Numbers” - and How We Get There

Therefore, the current population cap of 3,000 is an arbitrary human-generated number: it is not based on science, and is not representative of what the ecosystem can actually support. If the efficiency of bison grazing patterns and their remarkable ability to extract the most nutrition from the lowest quality forage is considered in conjunction with potential availability of public lands, this number should be much higher.

Because wild buffalo naturally travel in small herds (think family subgroup), the cumulative effects of yearly removals of entire large groups of bison within an isolated population result in a steady erosion of genetic integrity within this herd. This is a national tragedy and will ultimately result in the demise of this magnificent national treasure!

We must urge our public officials to discontinue the slaughter of Yellowstone bison in this manner. We cannot allow this recurring winter nightmare to continue.

It is key to the survival of the last wild buffalo and its future generations that current removal (slaughter) operations are immediately stopped. Prevention of further herd reductions will ultimately contribute to the conservation of these small herds, and augment global biodiversity.

We will continue to offer you more science, but right now we need you to act! Will you help us protect the last wild buffalo herds?

Yes! I’m ready to defend wild buffalo!

Issue: The Montana Department of Livestock (DOL) claims it slaughters the Yellowstone bison because they carry the disease “brucellosis.” This claim rings hollow when examined in the light of objective scientific fact.

buffalo field campaign science brucellosis beakers


Background:
Brucellosis was first detected in the Yellowstone Buffalo herd in 1917. The buffalo were exposed to brucellosis by domestic cattle that were (unwisely) allowed to graze in the park and confined with buffalo. Brucellosis is most commonly transmitted among and between species through ingestion of infected birthing materials.

Yellowstone buffalo developed a natural immune response to brucellosis and do not typically suffer from the disease. It is believed that many buffalo may also have a genetic immunity to brucellosis.

Failed pregnancies, the most common symptom of brucellosis, are relatively unknown in Yellowstone buffalo. The most likely mode of exposure among buffalo is ingestion of small amounts of bacteria from newborn live calves.

Essentially, the buffalo in Yellowstone are vaccinating themselves for brucellosis, developing an immune response, and clearing the bacteria. There isn’t a single a documented case of brucellosis transmission between buffalo and domestic cattle under natural conditions; ever! In Grand Teton National Park, where vaccinated cattle and brucellosis exposed buffalo have been commingling for decades, no transmission has ever occurred. The chances of transmission between wild buffalo and vaccinated domestic cattle have been characterized as “very low.”

Facts: A number of elements have led to the death of thousands of buffalo since 1985. The factors (which we explain in greater detail below) include the incidence and transmit-ability of brucellosis in buffalo; the distribution of cattle in the Greater Yellowstone Area; and the regulatory structure in place to reduce/eliminate brucellosis from the region.

Now we’ll explain things in even more detail, and share some additional but related information. Ready? Have you got your pocket protector in place?

Testing methods: There are currently two methods to test buffalo for brucellosis exposure and infection: serology and culture.

  • Serologic testing involves drawing blood from live animals to determine if long-term antibodies for brucellosis are present. Buffalo that test positive are considered infected and sent to slaughter. Approximately 45% of Yellowstone buffalo test sero-positive on the CARD test, the one most commonly used by the agencies.

  • The other method, culture testing, involves tissue sampling from slaughtered buffalo to determine if actual bacteria are present. Culture testing is considered to be the “gold standard” in determining infection.

  • Drastic differences between sero-positive and culture positive buffalo indicate that many buffalo are being slaughtered simply because they have developed immunity to brucellosis and are not actually infected. Would you take Chicken Pox medication if you had the antibodies but not the illness? Anyway, a combination of test results indicates that only between 2 and 20 percent of buffalo actually have brucellosis bacteria in their bodies at any given time.

  • Less Definitive Testing: Culture of tissues from slaughtered bison are no longer being done to confirm DOL field test results. In spite of these facts, DOL continues to use the results of both the FPA and the CARD tests, which sends low risk bison (i.e. bulls) to slaughter.

  • Inconclusive Results: Even if only the CARD test is positive and the more specific FPA is negative, buffalo are sent to slaughter. Why is DOL spending thousands of tax payer's dollars on new technology if it will not be properly utilized to save uninfected bison from needless slaughter?

Transmit-ability: The most likely method of transmission between species is ingestion of infected birthing materials or from an aborted fetus. Thus bulls, calves, yearlings, and non-pregnant females do not pose a significant risk of releasing infected materials in the environment. When a female buffalo is infected with brucellosis, she will pass the bacteria in her first pregnancy. After her first calving, her uterus will “super protect” itself from brucellosis, preventing infected material from being shed in subsequent calving even if she is re-exposed. Therefore, only pregnant female buffalo in the first calving cycle after exposure have the possibility of sloughing infected material into the environment. Brucellosis related abortions, even among infected females, are extremely rare in Yellowstone buffalo. Given the very small segment of the population that can even potentially transmit brucellosis and the low probability of transmission occurring in nature, the real chances of brucellosis transmission are extremely low. Additionally, brucellosis bacteria will not survive in warm weather or direct exposure to sunlight, and the activity of predators/scavengers all but guarantee that fetuses or infected birthing material will not persist in the environment beyond mid-May.

  • There has never been a documented transmission of brucellosis from wild bison to livestock. Even if buffalo were capable of spreading the disease, there are no cattle on these lands from mid-October to mid-June, making brucellosis transmission impossible.

Distribution of Cattle: Relatively few cattle graze in the Greater Yellowstone Area (GYA) at any time of the year, particularly in the winter and spring months when transmission is even a possibility. In the Western Boundary Area, no cattle are present within 45 miles of Yellowstone National Park in winter and spring. Cattle are typically only in the area between mid-June and mid-October, a period when there is no possibility of brucellosis transmission. The vast majority of cattle that graze in the summer in the Western Boundary Area are imported from Idaho and are already subjected to brucellosis vaccination and testing. In the Northern Boundary Area, there are never any cattle on the west side of the Yellowstone River between Gardiner and Yankee Jim Canyon.

One rancher grazes about 25 cows on the east side of the Yellowstone River and approximately 4 miles north of Gardiner on Rt. 89. This same producer brings his cattle to private land adjacent to the Eagle Creek Special Management Area (SMA) in the spring months. Untested buffalo are allowed to be in the Eagle Creek SMA, and no transmission of brucellosis has ever occurred. One additional producer grazes cattle on the east side of Yellowstone River north of Gardiner. Both of these ranchers have publicly stated that they welcome wild bison on their properties and are not concerned about a brucellosis transmission.

Regulatory issues: Montana is currently certified brucellosis class “Free.” Free status allows producers to transport reproductive cattle across state lines without brucellosis testing. The United States (US) is not certified brucellosis “Free” by the World Organization for Animal Health, the international regulatory body. Therefore, brucellosis testing is required to transport reproductive cattle across international boundaries. In order for the US to be certified brucellosis free, no livestock in the country can have been vaccinated for three years.

Bullying the Bulls is Bull: Many (some seasons, all) buffalo captured and slaughtered are bulls, which are incapable of transmitting the disease. Often slaughtered buffalo tested positive for brucellosis antibodies, but not the resulting infection. Because it is proven that bison build natural resistance to brucellosis, these animals (with antibodies but not infection) may actually be the strongest, healthiest animals of the herd.

The overwhelming majority of bison slaughtered according to these test results don't actually carry the disease. This means not only is DOL killing what we consider and hope to prove is an endangered species, they are killing the toughest of them...the ones that should be breeding future buffalo babies.

Antibody Detection: Most bison that test positive at a capture facility test negative under a more accurate post-slaughter necropsy. DOL uses a new testing methodology available for detecting antibodies to brucellosis in wild bison called the Fluorescent Polarization Assay (FPA). This testing method involves the use of antigens tagged with a fluorescent material which detect IgG (immunoglobulin G) type antibodies to brucellosis and bind with them. Binding between the antibody and the tagged antigen results in an increase in polarization which is detected by the analyzer and reported as a quantitative result. This result is interpreted as positive or negative based on certain value criteria. Studies have established that the specificity and sensitivity of this test were found to be much higher when compared to Particle Concentration Fluorescence Immunoassay and the CARD test.

However, in spite of the advanced technology of this testing method it is only capable of detecting IgG (long term immunity) antibodies, not the presence of brucella organisms. The major advantage of FPA over the CARD test is that it will detect a quantitative level of antibodies, which may or may not directly correlate to the presence of an infection, whereas the CARD test simply detects the qualitative presence or absence of antibodies. Although DOL has finally begun using advanced technology to detect brucellosis antibodies in wild bison, they are still unable to correlate their test results as proof of actual infection.

Conclusions:

Recap of facts:

  • Only a small percentage of Yellowstone buffalo are actually infected with brucellosis.

  • Brucellosis does not have any significant impact on the health of the Yellowstone buffalo.

  • The risk of transmission from wild buffalo to cattle is tiny, and there is not a single case of this happening, ever.

  • Relatively few susceptible cattle graze in the GYA, and most are not present during the time of year when the miniscule transmission potential could occur.

Simple solutions we propose:

  • Herd management plans that adjust cattle grazing dates could be easily implemented to completely eliminate transmission potential.

  • Montana can easily comply with the National Brucellosis Eradication Program to insure that brucellosis class “Free” status is preserved.

  • The GYA could be exempted from the OIE certification process (by keeping cattle out, period) and allow the rest of the country to enjoy international brucellosis free status.

  • Montana can develop risk management strategies for domestic cattle that allow free-roaming populations of wild buffalo in the GYA and beyond.

You Can Make a Real Impact for Wild Buffalo! As you can see, there are solutions to this issue, primarily related to sharing the facts and educating the public and legislators.
