State biologists have not spotted the wolves, which were dubbed the “Shasta Pack” because of their presence in the county home to Mount Shasta, since May, the San Francisco Chronicle reported last week. That’s puzzling because wolf packs typically stick to their territory. Then again, a lack of other wolves nearby could mean the family felt free to roam more widely.
“We’re reasonably confident that last year they did not use the same area as a pack as they did the year before, and we don’t know why,” Pete Figura, a senior environmental scientist for the department, told the Chronicle. “Why they were not detected anywhere else this past summer we don’t have a clear explanation for.”
Gray wolves are listed as endangered under both federal and California endangered species laws, which prohibit their killing. Some local ranchers weren’t delighted by the wolves’ arrival, especially after the pack was implicated in the death of a calf in October 2015. But Figura told the Chronicle that officials have no evidence the wolf family has been killed.
For now, he said, officials are awaiting DNA analysis of wolf scat found earlier this year near Siskiyou County, where the pack used to hang out. None of the wolves has been captured and fitted with a radio collar, which biologists use to track wild animals’ movements.
