Two years after the startling discovery of five newborn wolves in Siskiyou County, the California Department of Fish and Wildlife announced this week that three more wolf cubs have been found in western Lassen County — photographed while playing in front of a trail camera. 
  
 “We are excited by the discovery of a second pack. If two packs can be established, then others can get here,” said Jordan Traverso, a department spokeswoman. “This is historic wolf habitat and it’s great to see them return to where they were once all pushed out.” 
  
 Their birth represents the steady expansion of wolves across the western United States, restoring a creature that was once shot, trapped and poisoned to near extinction. They live somewhere southwest of Susanville in the dry, volanic and rugged landscape of Lassen National Forest. They are also believed to have wandered into Plumas County, where tracks were seen. 
  
 The discovery boosts the chances that this revered and reviled creature may be here to stay — recolonizing much of its historic habitat. 
  
 California’s wolves trace their lineage back to Canada — via Idaho and then Oregon. 
  
 Their ancestors were 35 animals were introduced from Canada into central Idaho in 1995 and 1996. These wolves then spread west into Oregon, then south to the Golden State, according to the Center for Biological Diversity. Wolves also were re-introduced to Yellowstone National Park, but they are not linked to California’s births. 
  
 Now, an estimated 1,700 wolves roam Montana, Idaho, Wyoming, Washington, Oregon and California. Last March, a California youngster — from the Siskiyou litter — moved into northwestern Nevada, becoming the state’s first wolf since 1922. 
  
 Oregon has 112 known wolves, with eight breeding pairs. Washington has 115 wolves, with 10 breeding pairs. 
  
 The Lassen litter traces its roots back to a lone male, called OR-7, which in 2011 was the first wolf to enter the Golden State in nearly a century. He trotted from southern Oregon into California, generating a Twitter feed of devoted fans and a fierce debate over wolf protection. 
  
 While OR-7 didn’t linger here long, soon returning to Oregon, one of his male offspring became a Californian — and sired this latest generation. The lineage of the female is unknown. 
  
 The two California litters are likely distant cousins. That’s because the Lassen County’s grandsire OR-7 was born in the Imnaha pack in 2009. And the Siskiyou pack also traces its heritage back to the Imnaha pack, from later litters. Their mother is OR-7’s sister. 
  
 “The Imnaha pack is therefore setting up quite a dynasty here in California,” said Amaroq Weiss, the West Coast wolf advocate for the Center for Biological Diversity. 
  
 “This is cause for enormous celebration and an important reminder that, if these animals are going to survive and thrive in California, we need to make sure they’re protected,” Weiss said. “Wolves lived in California for thousands of years and it’s really exciting to see them returning home.” 
  
 Pamela Flick of the environmental advocacy group Defenders of Wildlife called the discovery “an exciting new chapter in wolf recovery in the Pacific West.” 
  
 But their birth will fuel to the contentious debate over wolf management, an issue that’s followed its westward recolonization of its historic habitat. A lawsuit has been filed by the conservative Pacific Legal Foundation on behalf of California ranchers and farmers. They assert that there’s no proof that these wolves are the same subspecies originally native to California, so the state protection is illegal. 
  
 The California Farm Bureau Federation and the California Cattlemen’s Association are worried that if wolf populations continue to grow, their livestock is at risk. 
  
 Biologists suspected the presence of the Lassen pups on June 30, when they captured a 75-pound adult female gray wolf — and discovered she was still nursing. They quickly collected genetic and other biological samples, attached a GPS-equipped tracking collar and then released her. 
  
 She is the first wolf to be collared and tracked in California. The collar will collect valuable data about her travels, reproduction, survival and prey preferences, Traverso said. Although her location will not be public, biologists will track her travels relative to livestock and ranch lands. 
  
 The next day, during a routine follow-up, the biologists found tracks of what appeared to be wolf pups. Then a nearby trail camera, operated by the U.S. Forest Service, revealed photos of the female and three youngsters. 
  
 Gray wolves are currently listed as endangered by both the state and federal governments. Their management in California is guided by endangered species laws as well as the state’s “Conservation Plan for Gray Wolves In California,” finalized in 2016. 
  
 “Their return has been met with mixed emotion,” Traverso said. “Some see it as excellent news, after 100 years. But a lot of the land up there is used for cattle ranching and there is some concern, too, about people’s property. We look forward to gaining more information from the collared wolf about their habits.”

 Trail cameras in Lassen National Forest have confirmed that a female gray wolf collared by wildlife biologists has given birth to three puppies, only the second family of the revered predators in California in nearly a century. 
  
 The 75-pound female was captured in Lassen County on Friday after 12 days of trapping attempts and fitted with a collar containing Global Positioning Satellite technology, said Jordan Traverso, the spokeswoman for the California Department of Fish and Wildlife. 
  
 It was the first time a wolf in California had been fitted with a tracking collar. 
  
 “This is a pretty incredible conservation moment,” said Amaroq Weiss, the West Coast wolf organizer for the Center for Biological Diversity. “It’s the second time in 100 years that we know wolves have tried to raise a family in California, and it’s another sign that the state is good wolf territory.” 
  
 Fish and Wildlife biologists had known since fall that there was a wolf pair in Lassen County. Scat samples indicated the male was the son of OR-7, the famous wolf that entered California in 2011, roaming some 2,500 miles before returning to Oregon and creating what is now known as the Rogue Pack. 
  
 The wolf pair were detected again in May in Lassen National Forest, leading to the capture of the female. Biologists and veterinarians collected genetic and biological samples and discovered before releasing her that she had recently given birth. 
  
 On Saturday, biologists went to check on the wolf and found puppy tracks. When they checked a nearby trail camera operated by the United States Forest Service, they saw pictures of three gray puppies with their mother. 
  
 “It’s very exciting to have wolves returning to our landscape after 100 years,” Traverso said. “The pups are really cute and they are going to help us learn more about what they do and when they do it.” 
  
 The first confirmed breeding pair in California produced five pups in eastern Siskiyou County in 2015. It was the first pack of timber wolves, as they are also known, to establish itself in California in 91 years. 
  
 The family, called the Shasta Pack, was believed to have been responsible for the first reported case of livestock depredation in the state in more than a century. The seven members of the Shasta Pack — which all sport distinctive black coats — have not been seen in Siskiyou County since May 2016, but one of the grown pups was confirmed in northwestern Nevada in November. 
  
 The presence of Canis lupus in California is considered a milestone in the steady movement of wolves across the Western United States. Up to 2 million gray wolves once lived in North America, but Europeans, fed by big, bad wolf myths, drove them to near-extinction in the lower 48 states. 
  
 The last California wolf was killed in 1924. 
  
 The new Lassen Pack is known to have traversed both public and private lands, including timber lands, in western Lassen County and Plumas County. Traverso said the collar should help minimize wolf-livestock conflicts by providing information about the pack’s location relative to livestock and ranch lands. 
  
 Gray wolves are listed as endangered by both the state and federal governments.

"This is a pretty incredible conservation moment," a rep for the Center for Biological Diversity tells the San Francisco Chronicle following news from California: A second pack of gray wolves has been spotted in the state. State officials have known for about a year that a pair of gray wolves had hunkered down in Lassen National Forest, reports the San Jose Mercury News. But after trapping the 75-pound adult female last week, they determined the wolf had recently given birth. After taking samples and fitting the female with a tracking collar, they released her with high hopes. Later, a trail camera spotted her running around with three pups. A rep for the California Department of Fish and Wildlife says officials are "excited" because "if two packs can be established, then others can get here." Also of note: "The pups are really cute." The first gray wolf pack in California in nearly a century—made up of a male, female, and five pups—was spotted in Siskiyou County in 2015. The Siskiyou wolves are likely distant cousins to those in Lassen National Forest, officials say. But whereas the Siskiyou pack is descended from a wolf pack in northeast Oregon, the Lassen pack is descended from OR7, the first gray wolf to appear in California following the animal's extinction there in 1924. Specifically, one of OR7's sons is the mate of the female wolf captured last week. New granddad OR7 now resides in Oregon. (Wolf hunting may resume in these states.)
