Worm infests Wyoming Moose

May infect as many as 50% of Wyoming moose

In 2008 a moose was discovered in the Star Valley that suffered from both Chronic Wasting Disease and a carotid artery worm, Elaeophora schneideri. It now turns out that up to 50% of the population may have the worm but the true extent of the effects are unknown. The worm is transmitted by the bite of a horsefly which tend to do well under hot and dry conditions.

Judge overturns BLM grazing decision

This is what WWP calls “low hanging fruit”

Ely Sheep Grazing Allotments. The orange polygons represent bighorn sheep distribution and the red polygon represents the Warm Springs sheep trail. Click for larger view.

For the last several years I have been appealing grazing decision issued by the Ely District of the BLM and, over and over again, the District only considers alternatives which maintain the status quo even when they have identified problems on the allotments that are either caused by or exacerbated by livestock grazing.

The decision that was overturned and remanded back to the Ely District was for sheep grazing on 8 allotments encompassing 1.3 million acres of the Egan Field Office.  In their decision the BLM only considered two alternatives, one which would have renewed the previous 10-year decision without any changes; and one which would have renewed the permit with very minor changes in seasonal use, and placed very weak utilization standards on different components of the vegetation but kept the exact same number of grazing AUMs.  They didn’t consider a no grazing alternative or an alternative which would have reduced grazing levels at all.

Important developments on the Brucellosis front.

Montana and Wyoming infections and capture of elk.

The last week has been filled with many stories about brucellosis and its impacts on wildlife and livestock.

First, Montana has announced plans to capture and test elk for brucellosis then place radio collars on those females that test positive to see where they go and where they give birth.

Montana plans to capture 500 elk for disease testing.
By MATTHEW BROWN – The Associated Press

This comes at the same time that cattle in Wyoming have tested positive for brucellosis which has caused the state to implement wider testing to determine if there are other cases nearby.

Cows in Park County cattle herd test positive for brucellosis exposure.

On top of all of this news come reports that domestic bison on Ted Turner’s Flying D ranch have tested positive for the disease.  These are not the bison from the Yellowstone quarantine program.

In response to the infections of brucellosis in previous years the state of Montana implemented a plan which called for increased surveillance in counties which surround Yellowstone National Park in an effort to spare the entire state of losing its brucellosis free status in the event that further infections occur.

Livestock officials set meetings on brucellosis rule
The Belgrade News

All too often, when infections are found, officials blame elk before there is any evidence to support the claim.  While it may be likely that elk are behind these incidents it is important to investigate other sources in an effort to determine whether other cattle may be the source as well.

One thing has been determined with regard to past incidents, bison are not to blame.

DNA Tests Indicate Yellowstone National Park Elk, Not Bison, Most Likely To Spread Brucellosis

Don’t worry about the man behind the curtain.

In so many ways the issue of brucellosis in bison and elk is similar to the issue of domestic sheep diseases and bighorn except the rationalization for killing wildlife is just the opposite.

We now know that domestic sheep are responsible for disease issues in bighorn sheep and those who support the livestock industry want to simply deny it and continue to allow domestic sheep to use areas where there is an obvious conflict and to kill bighorn sheep if the “invade” the sacred domestic sheep allotments.

With bison the same argument is turned on its head so that bison are routinely hazed and slaughtered for being on the sacred landscape of the holy cow. Forget that there is absolutely no evidence to support the claim that bison are a truly a risk to cattle that are not even on the landscape when bison are capable of transmitting brucellosis. The bison must be tortured and killed so that the sacred cow can eat the grass that those pesky beasts are eating.

Well, now comes evidence to show that bison another species, elk, have been the culprit in spreading brucellosis to the sacred cow. Are we now going to see a new war waged against them? Forget that brucellosis came from domestic livestock in the first place. Something must be done to protect the kings and queens of the West and the taxpayer must fork over millions upon millions of dollars for a pointless and impossible eradication exercise so that the livestock industry won’t ever have to face any adversity.

Think it won’t happen? Well, it has already begun and the livestock industry will use this new study to rationalize it and to rationalize continuation of their bison policies as well.

National Coverage of Bighorn Sheep Disease Issues

Western Watersheds Project’s litigation and recent scientific studies changing the playing field.

Across the West domestic sheep operations threaten the viability of bighorn sheep populations and have caused serious declines because of the diseases they carry. Last winter there were ten populations that suffered from pneumonia outbreaks and many more are suffering the lingering effects of previous outbreaks which reduces lamb survival to very low levels for many years after the initial outbreak.

In Hell’s Canyon bighorn sheep are only a small fraction of the estimated 10,000 capacity. These sheep have faced a declining population because the lamb survival is too low to replace the adults that die of other causes. The Salmon River Canyon and Central Idaho herds have faced many of these same issues but they are the last remaining native bighorn in the state.

Western Watersheds Project has been working very hard to get the US Forest Service and Bureau of Land Management to develop scientifically based policies which would effectively keep bighorn sheep from ever coming into contact with domestic sheep. Unfortunately political interference by the woolgrowers and politicians has prevented the agencies from tackling this issue head on. Recently, though, the Payette National Forest decided to close about 70% of the sheep grazing area due to concerns of disease. This is one of the first cracks in the armor of the oligarchical system which holds great political sway but provides little, if any, economic benefit to the public for the subsidies it provides.

The Payette Bighorn Sheep Viability Decision has been appealed by Western Watersheds Project; the Oregon Department of Fish and Wildlife; the State of Washington, Department of Fish & Wildlife; the Nez Perce Tribe with other groups; and the Confederated Tribes of the Umatilla Indian Reservation primarily because it implements the decision gradually over a period of three years rather making the closures all at once. The Idaho Woolgrowers Association et. al.; Soulen Livestock Company; Frank Shirts Jr., Shirts Brothers Sheep, & Ronald and Leslie Shirts have all appealed the decision because it threatens their interests. One glaring absence is the Idaho Department of Fish and Game who recently issued a Draft Bighorn Sheep Management Plan which essentially maintains the status quo because it feels it has no power to influence the decisions of the Federal land management agencies. This would be an incorrect assumption if it weren’t for the political interference of the small but politically powerful group of woolgrowers on the legislature.

New Study Comfirms that Bighorn Sheep Die from Domestic Sheep Diseases

Hells Canyon Bighorn Sheep © Ken Cole

Hells Canyon Bighorn Sheep © Ken Cole

A new study in the Journal of Wildlife Diseases confirms, unequivocally, that the domestic sheep disease Mannheimia haemolytica kills bighorn sheep after the two species co-mingle. This paper has been rumored for the last several months and was cited in the recent Payette National Forest decision to close 60% of sheep grazing allotments on the Forest.

Surely this should end the discussion among reasonable people about whether science supports the notion that domestic sheep and bighorn sheep can co-exsist. They cannot and actions must be taken by Federal and State agencies to make sure that the two species do not overlap on the landscape.

ABSTRACT:   Previous studies demonstrated that bighorn sheep (Ovis canadensis) died of pneumonia when commingled with domestic sheep (Ovis aries) but did not conclusively prove that the responsible pathogens were transmitted from domestic to bighorn sheep. The objective of this study was to determine, unambiguously, whether Mannheimia haemolytica can be transmitted from domestic to bighorn sheep when they commingle. Four isolates of M. haemolytica were obtained from the pharynx of two of four domestic sheep and tagged with a plasmid carrying the genes for green fluorescent protein (GFP) and ampicillin resistance (APR). Four domestic sheep, colonized with the tagged bacteria, were kept about 10 m apart from four bighorn sheep for 1 mo with no clinical signs of pneumonia observed in the bighorn sheep during that period. The domestic and bighorn sheep were then allowed to have fence-line contact for 2 mo. During that period, three bighorn sheep acquired the tagged bacteria from the domestic sheep. At the end of the 2 mo of fence-line contact, the animals were allowed to commingle. All four bighorn sheep died 2 days to 9 days following commingling. The lungs from all four bighorn sheep showed gross and histopathologic lesions characteristic of M. haemolytica pneumonia. Tagged M. haemolytica were isolated from all four bighorn sheep, as confirmed by growth in ampicillin-containing culture medium, PCR-amplification of genes encoding GFP and ApR, and immunofluorescent staining of GFP. These results unequivocally demonstrate transmission of M. haemolytica from domestic to bighorn sheep, resulting in pneumonia and death of bighorn sheep.

Reminder: Comments Due on IDFG’s Bighorn Sheep Plan Tomorrow

I posted this at the end of August. It’s time to get your comments in.

Don’t color outside the lines

Bighorn Sheep © Ken Cole

Bighorn Sheep © Ken Cole

The Idaho Department of Fish and Game has released its Draft Bighorn Sheep Management Plan which essentially draws lines around existing bighorn sheep populations and prevents recovery to historical habitat. This is a big problem because the bighorn population has been in steep decline due to diseases spread by domestic sheep.

A population that recovered from over hunting and disease in the late 1800’s and early 1900’s started to increase after hunting regulations and reintroductions took place but the recovery was short lived and now the native and reintroduced populations have suffered from repeated contact with diseased domestic sheep and goats. The population numbered around 5000 in the 1990’s but is now about 2900 and continuing to decline.

Two areas, the Pioneer Mountains west of Mackay, and the Palisades east of Idaho Falls, are areas where dispersing sheep are commonly seen. Under this plan these areas have been essentially written off due to the presence of Federal sheep grazing allotments. Another area that isn’t included as a priority area for sheep recovery is the Sawtooths and the Boise and Payette drainages. These areas contain very suitable habitat yet there are domestic sheep allotments there as well.

The Management Plan is not likely to curb the declines in bighorn sheep populations and the IDFG is afraid to advocate for bighorn sheep conservation. They hold the power to really make the Federal agencies pay attention and close sheep grazing allotments but the IDFG is a captured agency that depends on the good graces of the livestock industry dominated legislature.

After last winter’s disastrous die-off of bighorn sheep in Montana, Utah, Nevada, and Washington State it seemed the news couldn’t get any worse for bighorn sheep. Well, today comes news of another outbreak of pneumonia in a heard of 100 bighorn sheep east of Hamilton, Montana. Officials have shot 8 of the sheep and have found at least 5 were suffering from pneumonia.

Payette National Forest Bighorn Sheep Decision Imminent

The Payette National Forest will be releasing its Record of Decision on July 30th

Hells Canyon Bighorn Sheep © Ken Cole

Hells Canyon Bighorn Sheep © Ken Cole

After several years of litigation, the decision on how to manage domestic sheep on the Payette National Forest to maintain viability of bighorn sheep populations will be released on July 30. Several options were considered but few actually meet the so called “purpose and need” of the decision. Regardless of the decision, litigation will likely follow as there is a lot at stake.

Bighorn sheep, which have struggled with disease outbreaks caused by contact with domestic sheep, in Hells Canyon and the Salmon River Canyon will be affected by the decision. There are estimated to be approximately 1,000 California Bighorn Sheep and 1,800 Rocky Mountain Bighorn Sheep in Idaho and only 700 of those are native Rocky Mountain Bighorn Sheep which live in central Idaho. This is approximately half of the population that existed in the late 90’s and trends indicate further declines.

Of greatest concern to the bighorn populations in Idaho is contact with domestic sheep and the fatal diseases which they carry. The limiting factor in the populations continues to be pneumonia and not weather, habitat, or predation. If the adult bighorn sheep are not dying outright from disease through contact with domestic sheep then their lambs are dying within weeks of being born thus, the bighorn are not replacing themselves at a rate fast enough to keep up with other mortality factors and are continuing to decline in population. For years after an outbreak lamb survival is the limiting factor.

From an email sent today by Forest Supervisor, Suzanne Rainville:

“The Record of Decision for the Final Supplemental Environmental Impact Statement and Forest Plan Amendment Identifying Suitable Rangeland for Domestic Sheep and Goat Grazing to Maintain Habitat for Viable Bighorn Sheep Populations will be available to the public July 30 when it will be posted in the Federal Register. We plan to have documents available on the Forest website by July 27. I will be hosting a briefing of my decision on July 28 at the Boise National Forest Supervisor’s office at 10:00 AM in the Sunset and Bear Valley Conference Rooms. The address is 1249 S. Vinnell Way, Suite 200 (second floor above Social Security).”

Domestic sheep removed from East Fork Bitteroot

Sheep tested positive for Mycoplasma ovipneumoniae

Bighorn sheep in Montana and elsewhere suffered severe losses this winter at the hands of pneumonia. In the East Fork herd bighorn were seen interacting with domestic sheep near Sula, Montana. Those domestic sheep were relocated earlier this year and another herd has been removed from the area to protect the remaining 87 bighorn sheep that survived the outbreak this winter.

Survival of lambs is the big remaining concern in the affected populations and it is being closely monitored.

We wrote about this story last December: Second brucellosis case found in Idaho cattle herd. It turns out that 7 cattle tested positive in the herd that was assembled over the last two years. The origins of the animals have not been reported. The remaining animals are being kept in quarantine.

Idaho State Veterinarian Bill Barton was quick to blame elk as the source of the outbreak but there has been no source identified. Will the results of the epidemiology be released?

More on the Montana bighorn disease outbreaks

Same pathogen found in bighorn and domestic sheep after contact was observed

Bighorn Sheep © Ken Cole

Bighorn Sheep © Ken Cole

Here are two stories outlining what happened this winter with the outbreaks of disease in bighorn sheep.  It appears that there are likely two different causes for the outbreaks.  In the East Fork Bitterroot it appears that bighorn contracted mycoplasma from a small herd of domestic sheep near Darby where the owner reported contact.  The sheep were later tested for disease and the samples matched what was found in the bighorn sheep.  To the north and east in the upper and lower Rock Creek herds and the Bonner herd it appears that something else is going on but, even though there are many domestic sheep in close proximity to these bighorn herds, no documented contact has been observed.  That doesn’t say much though and doesn’t eliminate the likelihood that contact occurred.  We’ve had reports on this blog of seeing domestic sheep in an area one day and bighorn sheep in the same area the next in this region.

It should be noted that the owner of the domestic sheep in the Sula, Mt. area has moved the sheep and is hoping that a new home can be found for them in an area that doesn’t have bighorn sheep.

Fortunately the outbreaks haven’t been as devastating as others on the basis of percentage.  Still, the overall numbers of bighorn sheep lost is staggering and the effects of the outbreaks will likely impact lamb survival for years to come.

Idaho Wool Growers Sue IDFG Over Bighorns

Bighorn Sheep © Ken Cole

Bighorn Sheep © Ken Cole

The Idaho Wool Growers Association and Shirts Brothers Sheep are suing the Idaho Fish and Game Department over an agreement that they signed in 1997 which would hold woolgrowers harmless if bighorn sheep introductions caused harm to their business. There are a number of problems with the agreement which make it unenforceable.

According to the lawsuit, “The Idaho Department of Fish and Game took no action to block the Forest Service from modifying the grazing allotments for Shirts and Shirts Brothers and took insufficient action to prevent Shirts and Shirts Brothers from being harmed by these actions”

I don’t know how the IDFG could block the Forest Service from making these changes. The IDFG has no control over the actions of the Forest Service. The IDFG does not manage grazing privileges on the National Forests and even if the lawsuit is successful it will not change the obligations of the Payette National Forest under the National Forest Management Act which requires them to manage the Forest in a manner which maintains the viability of native or desirable species, including bighorn sheep which have declined in number to only 3500 statewide.

In response to litigation by Western Watersheds Project, the Payette National Forest is drafting a Supplemental Environmental Impact Statement which proposes an alternative which may close up to 60% of the Forest’s sheep grazing allotments to keep domestic sheep separate from bighorn sheep that inhabit Hell’s Canyon and the Salmon River Canyon.

Domestic sheep are known to carry diseases which are deadly to bighorn sheep and are likely to have killed hundreds of bighorn sheep throughout the west this winter.

WAFWA report summarizes pneumonia outbreaks in bighorn sheep

A report, dated March 16, 2010, by the Western Association of Fish and Wildlife Agencies, Wild Sheep Working Group, summarizes the recent outbreaks of pneumonia in bighorn sheep that have occurred in Montana, Nevada, Washington, Utah, Wyoming, and South Dakota.  Domestic sheep and goats are also known to be in close proximity to, and are suspected to have interacted with, bighorn sheep in many of the areas where outbreaks have killed hundreds of wild sheep region-wide. Contrary to recent reports in the media, there have been confirmed interactions between bighorn and domestic sheep associated with at least one of these outbreaks.  Most notably there has been confirmed interaction in Montana where there have been severe outbreaks of pneumonia.

The report outlines many of the actions taken by the state agencies and what testing has been done. Many of the tests are still being conducted on samples from bighorn and domestic sheep and no conclusive results have been announced.  It cannot be said that there has been no interaction between domestic and wild sheep.  At the same time it cannot be said for certain that interaction has been the cause of all or any of these outbreaks, however there is overwhelming evidence that interaction between domestic sheep and goats results in widespread and rapid die-offs of bighorn sheep.

Bighorn Sheep © Ken Cole

In 2007 the WAFWA Wild Sheep Working Group was created to give guidance to state, federal, and provincial agencies on how to manage domestic sheep and goats in wild sheep habitat.  They produced a report to the agencies in June of 2007 but none of the recommendations have been implemented by the BLM or Forest Service.  There are still numerous conflicts on the ground where domestic sheep and goat grazing is allowed within occupied bighorn sheep throughout the west.  In some cases these conflicts have resulted in litigation and changes to land management plans are underway.

WAFWA Recommendations for Domestic Sheep and Goat Management In Wild Sheep Habitat

It is time for the BLM and Forest Service to implement strict guidelines which maintain separation between bighorn sheep and domestic sheep and goats.  At minimum, permits for grazing and trailing sheep and goats on Federal lands in occupied bighorn habitats should be withdrawn.  Farm flocks on private lands deserve some attention too.  Programs for educating owners of farm flocks should be created and in some cases effective fencing to eliminate contact between the two should be offered or even required in areas where bighorn sheep are of high conservation value.

Bighorn Sheep in Salmon River Canyon © Ken Cole

Populations of bighorn sheep are struggling with pneumonia throughout the west. Washington, Nevada, Montana, and most recently Utah are having outbreaks of pneumonia which have resulted in the deaths of 400 or more bighorn sheep.

Statements like the following are often made about the outbreaks.

“While domestic sheep carry pathogens that can infect bighorns, there’s no evidence linking them to any of the pneumonia outbreaks, wildlife officials said.”

But pneumonia does not just appear from nowhere, it has to come from somewhere. Were these diseases already in the herds from earlier exposures and have just become deadly due to winter conditions or have they been introduced to the wild sheep through contact with domestic sheep or goats recently?

There are four disease outbreaks among bighorn sheep herds in the news this winter, two in Montana, one in Nevada, and one in Washington State. This is the time of year when bighorn sheep are concentrated so diseases are more easily transmitted.

There has been no mention of where these sheep contracted pneumonia but, as I mentioned in the recent story about this, there is domestic sheep grazing in an effort to control weeds in the nearby mountains. Could this be the cause?

This is very bad but expected news. Both the BLM and the US Forest Service authorize domestic sheep grazing in areas near these bighorn populations. While there has been no mention of any interaction between domestic livestock and bighorn sheep there have been goats used to control weed in the Clover Valley just east of the East Humboldts.

In 1997 there was a die-off of both bighorn sheep and mountain goats in the Ruby Mountains where a large percentage of the animals were lost.

It bugs me that both the USFS and BLM are waiting on the Payette Forest to determine what they are going to do about sheep grazing in bighorn sheep habitat before they develop a policy to address this issue in other areas. The science is clear and the need for a strong policy is obvious. Why are they waiting?

Livestock disease found in eastern Idaho cow

The infected animal had been vaccinated.

This has been a perennial issue in areas surrounding the elk feedlots in Wyoming. It now seems that brucellosis has once again infected cattle in Idaho but it is too early to say where the disease originated. If brucellosis is found in another cattle herd in Idaho within a year then Idaho, once again, will lose its brucellosis free status and all cattle that are exported will have to be tested for the disease.

For years this scenario was held over the heads of people who support free roaming bison in Montana yet, when it came to pass, it turned out to be more of a minor inconvenience rather than the catastrophe the livestock industry claimed it would be.

This issue has been used rather effectively against wildlife for years but the disease is much less of a threat to human health than it was before the pasteurization of milk became the standard. The only way to contract brucellosis is by coming into direct contact with infected fetal tissue or by drinking unpasteurized milk. You cannot become infected by eating cooked beef.

Sick bighorn reported near domestic sheep

One, possibly more, bighorn sheep to be killed.

Update 5/31/09: It gets worse. Sick, wandering bighorn trailed near Salmon River. Idaho Statesman.

Bighorn Sheep ©Ken Cole

A bighorn sheep ram has interacted with domestic sheep on private property upriver from Riggins, Idaho and is reported to be sick. It is now associated with several other bighorn sheep. IDFG officials have decided to kill the sick ram but officials have not decided how to handle the situation regarding the other sheep. There is the possibility that the remaining sheep may be killed as well.

The Nez Perce Tribe has been closely monitoring bighorn sheep in the Salmon River Canyon in recent years in an effort to document how bighorn sheep use the canyon. This monitoring shows that this kind of interaction can and does occur.

The owner of the domestic sheep holds permits on nearby BLM and Forest Service allotments but has been prevented from running sheep on the Forest Service allotments but the BLM continues to allow grazing on their allotments at the expense of bighorn sheep which are very susceptible to pneumonia that are carried by domestic sheep. There have been numerous die-offs of bighorn sheep around the country that are due to these types of interactions.

It is particularly negligent for the BLM to allow continued domestic sheep grazing in this area but they have resisted efforts to close the allotments and it is contrary to their own recommendation and that of Western Association of Fish and Wildlife Agencies (WAFWA) of maintaining a minimum 9-mile separation between bighorn sheep and domestic sheep.

Bighorn Sheep/Domestic Sheep Advisory Group Meetings Suspended.

Collaborative effort to save public lands domestic sheep grazing suspended in favor of a more closed process mandated by the Legislature and the Governor.

The Governor, Legislators, and sheepmen apparently didn’t like the direction the Bighorn Sheep/Domestic Sheep Advisory Group was headed so the whole effort was scuttled…… for now. Many of the groups participating in the group didn’t sound favorable to putting their stamp of approval on continuation of the status quo.

I guess all of those long meetings where bighorn sheep were hardly talked about didn’t amount to much. Now it’s time for people to give input into the process where “Best Management Practices” are developed cooperatively between the sheep permitees and the Idaho Fish and Game. Will they listen to outside input? Do they have to? Will the BMP’s be acceptable to the US Forest Service? Will the BMP’s continue the same old practices?

I received this message while I was away on vacation:

To all the individuals who have been involved in the Bighorn Sheep/Domestic Sheep Working Group:

After considerable discussion, we have decided to delay further meetings of the Bighorn Sheep/Domestic Sheep Working Group. As most of you are aware, a new statute is in place, S1232a, which directs Idaho Fish and Game to “within ninety (90) days of the effective date of this act will cooperatively develop best management practices with the permittee(s) on the allotment(s).” Under this timeline the Idaho Department of Fish and Game with the Idaho Department of Agriculture will be very busy working with individual producers to develop best management practices. Unfortunately, this timeline will not accommodate a collaborative process.

We do intend to reconvene the working group in late summer or early fall and appreciate everyone’s effort to date. Additionally, we would like to invite all working group participants to submit BMP comments to IDFG within the 90 day period.

Sincerely,

Brian Oakey
Deputy Director
Idaho Department of Agriculture

U.S. is declared “brucellosis free” (except for wildife).

Let’s all cheer. USDA has declared U.S. brucellosis free except for Yellowstone and Grand Teton National Park elk and bison.

“We must now focus our efforts on eradicating brucellosis from the free-ranging elk and bison populations in the Greater Yellowstone Area in order to protect our national cattle herd against future outbreaks of this disease.”  These are the words of some Bush USDA undersecretary.

Lies. Lies. The disease is not perpetuated in these national parks.

As we comb Bush’s phony budget, I think we can find some funds to cut here unless they start to focus on real disease threats.

USDA News Release 

Idaho bighorn/domestic sheep consensus group meets, and sheep disease transmission not on the table.

Earlier, we ran an exclusive story that the livestock industry and various officials were having a secret meeting at the request of Idaho’s governor to counter the federal courts because they were insisting that sheep operations keep their disease-ridden bands away from bighorn sheep in Hells Canyon (Idaho/Oregon border) and on the lower Salmon River in Idaho.

Dec. 3, 2007. Rumor of high level Idaho meeting to conspire against recent bighorn sheep victories.

It was true, and the so the whole thing emerged on Jan. 7 as a consensus group meeting attended by a number of groups, but the agenda was tightly controlled.

Once again what is so fascinating is how little stockgrowers are concerned about passing livestock disease to wildlife.

The Western Watersheds Project blog has an interesting account of the group’s first meeting, at least I find it appallingly entertaining. Read “Bighorn Meeting.WWP blog.

Similarly why is it that the ag lobby’s kept agency, APHIS, is doing so little about bluetongue which is a grave threat to whiletailed deer, pronghorn and a number of ruminant livestock.?
