“We’ve been doing grazing applications like this for 30 years and plan to have as little influence as attainable on Missoulians who recreate on these lands,” Helle mentioned. “We’ll be bringing in a bigger herd than you’ve probably seen up to now, which suggests we’ll be capable to transfer from one location to the following faster and end in much less time.”

Subsequent March, the Rambouillet sheep will likely be shorn and their Merino wool will likely be despatched to amenities throughout the USA for spinning, knitting, dying and garment manufacturing. Helle mentioned that wool has made a resurgence in recognition in recent times after dropping floor to artificial fibers.

“Merino wool can be a magic materials,” he mentioned, noting that sheep have been selectively bred to verify the wool is much less itchy on human pores and skin.
