The Largest Litter In 100 Years: Wolves Are Making A Remarkable Comeback In California

The births in the Whaleback wolf pack happened in the spring but were only recently confirmed by the CDFW. Their arrival offers signs of a remarkable comeback after wolves were wiped out in the state more than a century ago.

"This is a really great sign of the health of wolves," said Amaroq Weiss, a biologist who works as the senior wolf advocate for the Center for Biological Diversity. A typical litter is usually five or six pups, she said.

"The fact that eight pups have made it this far into the year is really exciting," Weiss added.

Wolves were hunted to near-extinction in California. They were never reintroduced in California, but began to slowly make their way into the state from Oregon in 2011.

"We used to have wolves here and now they are back, using the landscape and still producing offspring," Weiss says.

California is home to two other packs: the Lassen pack and the Beckwourth pack. The Lassen pack has produced offspring every year since it was confirmed in 2017. Less is known about the Beckwourth pack. The CDFW reported "some smaller tracks" in September, indicating a possible pup.

The Whaleback pack was only confirmed in 2020, and had a litter in 2021 – and now a second in a row.

"It's really a remarkable thing that has happened here," says Weiss. "It's pretty rare where you have nearly eradicated a species and it starts to come back on its own."
