Areas of the Big Horn National Forest near Sheridan and Buffalo are playing host to a new species of moth.
Forester, Chris Thomas, explains.
Thomas said according to last year's estimate, approximately 2000 acres of the southeast portion of the Big Horn National Forest have been affected by the visitors. For example, trees near the South Fork Lodge are still in recovery.
Thomas said the Rustic Tussock Moth is is native to areas much farther north in the Canadian wilderness, and their appearance here a mystery.
Thomas said scientists will keep a close eye on the species this year.
