Survival of bighorns in Tetons a mystery

This is from the Jackson Hole News and Guide. It’s about how 100 bighorn sheep struggle to survive in the heights of the Tetons. It is a marginal existence, but the destruction of the bighorns of the Snake River Range and other mountain chains to the south and southeast, which would provide better habitat is not due to human development like the article says.

It is sheep, domestic sheep, disease-spreading domestic sheep.
