Last month, on a remote, snow-dusted rise high in Montana’s Gravelly Mountains, I found myself beset by an army of livestock.
The sheep came over the hill in martial lines, a fleecy
platoon framed by the teeth of the Madison Range, guard dogs nipping at
their cloven heels like irate sergeants. The four-legged troops quickly
captured our knoll, and my companions and I retreated to our car to
watch the flock tug at the brown grass. Eventually a solitary horseman
appeared along the ridgeline and began coaxing the sheep toward lower
ground. It was mid-September, and the mountain grazing season had
reached its end — for the final time, if conservationists get their way.
I had, perhaps, witnessed the last hurrah of the Beaverhead-Deerlodge
flock.
...Grazing also impedes the recovery of bighorn sheep, which are susceptible to contracting pneumonia
from their domestic brethren. To avoid devastating outbreaks, wildlife
managers strive to prevent wild and domestic sheep from mingling on the
range, effectively precluding bighorns from vast swaths of public land.
In Montana, the standoff has proved disastrous to bighorn recovery.
Though the state vowed in 2010 to create five new bighorn herds over a
decade, there’s nowhere to stick the ungulates that wouldn’t expose them
to disease. The situation has gotten so bad that some officials say
Montana would be better off shipping its sheep to South Dakota.
Though bighorn sheep were reintroduced near the Gravelly
Mountains in 2002, that herd comprises only 35 animals, far below the
125 that Montana deems a viable unit. Nearby herds are hardly faring
better. According to conservationists, that’s because grazing’s giant
hoofprint has kept bighorn herds too small and isolated to thrive.
“The question is, are we really going to allocate all this public land to domestic sheep influence?” demands Glenn Hockett, president of the Gallatin Wildlife Association.

More false science purporting that domestic sheep pass on pneumonia to Bighorns. A snail is the intermediate host for the lung worm and it must be ingested by a grazing ungulate to pass it into the lungs. This is just another attempt to get all grazing use off of the national forests.
