Please read this study proving pack goats are safe for Bighorn sheep. I would never pack my goats into an area if I thought they would destroy such a limited and valuable resource. Hope you don't take this the wrong way but when people state false facts it hurts us with goats. They are trying to ban goats from the backcountry but it's the domestic sheep that is the problem.

I read the two articles on the site you referenced, and neither prove pack goats are safe for bighorns. In fact, one suggests the opposite and the other is very specific in that its results were inconclussive because the domestic goat test studies did not have the Pasteurella strain that is deadly to wild sheep and that more relevant study is necessary.
From "Goat Health Issues - Pasturella - Pasturella-Searching for the Truth/Hells Canyon Die-Off"
"Limited data exist on the relationship between domestic goats, bighorn sheep and the transfer of potentially lethal Pasteurella spp. known to be pathogenic to bighorn sheep. Thus, interactions between the two species on the range should be considered a potential risk factor that may impact bighorn sheep habitat, both while on the trail and at the campsite. Likewise, we recommend that bighorn sheep which are near domestic goats be hazed or removed from the population."
The other article indicates that more study is necessary because the domestic goats and cattle in question did not have the Pasteurella strain that causes death in wild sheep.
From "Goat Health Issues - Pasturella - Pasturella-Research into Transmission into Big Horn Sheep" (see last sentence)
"As a result of these and previous studies, specific management recommendations can be made. All contact between bighorn sheep and domestic sheep or mouflon sheep must be prevented or it is likely that the bighorn sheep will die from pneumonia after close contact with these species. Based on available data, bighorn sheep contact with elk (Cervus elaphus), deer (Odocoileus virginianus and O. hemionus hemionus), mountain goats, or llamas apparently does not result in respiratory disease in bighorn sheep (Foreyt 1992b, this study). Trials with domestic goats and cattle did not result in respiratory disease in bighorn sheep under the conditions described in this experiment. However, similar trials need to be conducted with domestic goats and cattle that are carriers of Pasteurella haemolytica biotype A to determine the effects of those organisms on the health of bighorn sheep."
