Bear Naked Truth

Facing a host of challenging medical ailments and a less-than-hopeful prognosis, an approximately 10-month-old male black bear from South Lake Tahoe was humanely euthanized on Monday at the Oakland Zoo where he was receiving treatment. The California Department of Fish and Wildlife’s (CDFW) veterinary team remained in close contact with the Oakland Zoo’s veterinary team, and after considering treatments and likely outcomes agreed that the cub was unlikely to have a good quality of life even if treatments were successful.

“This poor cub had a whole host of medical issues,” said CDFW Wildlife Veterinarian Dr. Brandon Munk. “He was never going to be a normal bear again and would have required lifelong medical care in captivity. We didn’t want a poor quality of life for the bear and undue strain on any zoo or sanctuary caring for him.”

The severely underweight bear was brought to CDFW earlier this month after he was found in a public area of South Lake Tahoe. The bear was suffering from significant pneumonia, a broken foot with an infection that was likely spreading to surrounding bones, a dislocated wrist, severe hair loss and skin ulceration caused by fungal and bacterial infections, gastrointestinal parasites, an ear infection and an umbilical hernia.

CDFW received the bear on Nov. 10, did an assessment and on Nov. 11 transferred the bear to Oakland Zoo’s world-class veterinary medical facility. The zoo’s veterinarians were successful in relieving the bear’s pain and discomfort and stabilizing his condition. However, the bear’s condition worsened despite treatment. If veterinarians would have continued treatment, the bear would have required round-the-clock sedation, as well as potentially placing him on a ventilator.

“The fact that he had worsened, despite treatment, and would have required the highest level of invasive care, were the biggest deciding factors for euthanasia,” said Oakland Zoo Senior Veterinarian Dr. Ryan Sadler. “The potential for this bear to have a good life under human care, even with significant veterinary intervention, was very low. We didn’t want to see him undergo months of stress and painful treatment only to be left with conditions that would cause discomfort throughout his life.”

Hopeful news to report from the Tahoe Basin on National Black Bear Day, which is recognized annually the first Saturday in June.

ABC 7 Los Angeles shared video recently of what Tahoe Basin residents believe to be the Tamarack Fire bear splashing and playing happily in a South Lake Tahoe pond. California Department of Fish and Wildlife (CDFW) officials say they can't know the bear's identity for certain since the Tamarack Fire bear wasn’t tagged or radio-collared prior to its escape but their hope is that residents are correct and the Tamarack Fire bear is the one enjoying itself in the ABC 7 video.

The Tamarack Fire bear, you’ll remember, made headlines last summer and prompted local concern after the young bear escaped from its enclosure at Lake Tahoe Wildlife Care, where it was recovering from burns suffered in the Tamarack Fire.

CDFW ultimately decided against recapturing the bear after various sightings and observations in the wild revealed the bear to be moving and functioning properly with no obvious signs of injury and behaving as a wild and healthy bear should. Surrounding fresh scat indicated the bear was actively foraging on wild foods. More information on the decision is available in an earlier post.

While conflict bears in the Tahoe Basin often capture the attention and interest of the news media and the public, it’s good to be reminded that many of the Tahoe Basin’s black bears still live healthy, wild lives free from human conflict and – mostly – out of the spotlight.

On National Black Bear Day, we can thank ABC 7 Los Angeles – and perhaps the Tamarack Fire bear itself – for the reminder.

A Siskiyou County man has pleaded guilty to unlawful possession of two bear cubs and obstructing wildlife officers, the California Department of Fish and Wildlife (CDFW) announced recently. Cody Dylon Setzer, 29, Yreka, took two bear cubs from their den and sow (mother bear) after finding the den site in a fallen log across a forest road. The bear cubs were estimated to be less than four weeks old at the time Setzer took them.

Wildlife officers became aware of the bear cubs on March 9, 2019, when Setzer called them, claiming he had found the cubs along the roadside on Highway 263 north of Yreka. A wildlife officer became suspicious of Setzer’s story when no bear tracks or habitat were found at the location where Setzer claimed he had found them.

The bear cubs were transported to CDFW’s Wildlife Health Laboratory in Rancho Cordova. Wildlife forensics scientists with CDFW’s Wildlife Forensics Laboratory used DNA samples to establish the bear cubs were likely born in the Sacramento River canyon in northern Shasta County, more than 90 miles south of where Setzer claimed he had located them.

During the investigation, wildlife officers determined Setzer and a co-worker at a local timber management company took the cubs from a den inside a tree that had fallen across an access road to a work site. The co-worker took officers to the location of the den site east of Salt Creek and Interstate 5. Further evidence was collected from the den site, which had been destroyed by both men. The sow was never located.

The cubs were turned over to Lake Tahoe Wildlife Care (LTWC) for long-term rehabilitation. LTWC said the cubs were the youngest ever brought into its facility. After growing old enough to survive on their own, the cubs were returned to their native habitat in Shasta County on April 28, 2020.

On Nov. 17, 2021, Setzer pleaded guilty in Siskiyou Superior Court to possession of a prohibited species and obstructing a peace officer in the course of his duties. Coincidentally, Setzer had also been prosecuted for a separate, unrelated case and the district attorney’s office agreed to combine sentencing for both.Due to his guilty plea on both cases, he was ordered to pay $2,290 in fines and fees and complete 200 hours of community service. Setzer was also placed on probation for 12 months with his hunting and fishing privileges suspended for the duration of his probation, and sentenced to 90 days in the county jail, which will be stayed if he successfully completes probation.

Within hours of receiving authorization to care for bear cubs again, Lake Tahoe Wildlife Care welcomed an orphaned, 25-pound bear cub from Tulare County to its improved South Lake Tahoe facility December 8, 2021.

Three more orphaned cubs – two siblings from the South Lake Tahoe area and a third cub from the Coleville area in Mono County – were transferred shortly thereafter from Gold Country Wildlife Rescue in Auburn to Lake Tahoe Wildlife Care to prepare the cubs for hibernation in a high-country climate similar to where they were rescued and where they will ultimately be returned to the wild.

“Lake Tahoe Wildlife Care is an important partner, one with decades of experience rehabilitating and releasing bear cubs back to the wild,” said Dr. Brandon Munk, wildlife veterinarian for the California Department of Fish and Wildlife (CDFW). “We’ve been working closely with them to ensure we are all maintaining the best possible standards for bear rehabilitation in this state.”

Munk was among five CDFW employees who conducted a site inspection of Lake Tahoe Wildlife Care’s facilities December 7, 2021 prior to renewing its permit to temporarily possess and rehabilitate injured and orphaned black bear cubs.

Lake Tahoe Wildlife Care operates under a CDFW wildlife rehabilitation permit to conduct care and rehabilitation of native wildlife -- excluding big game species such as deer, elk, and black bears. Lake Tahoe Wildlife Care had a secondary agreement with CDFW to rehabilitate black bear cubs that expired on July 22, 2021. Efforts to renew that secondary permit were temporarily delayed by the much-publicized escape this summer of a bear cub injured in the Tamarack Fire while recovering at Lake Tahoe Wildlife Care.

CDFW required Lake Tahoe Wildlife Care to make several improvements to its facility enclosures and fencing as part of the permit renewal process to possess bears.

Lake Tahoe Wildlife Care is just one of four wildlife rehabilitation facilities in the state permitted to care for black bear cubs, joining Gold Country Wildlife Rescue in Auburn, Sonoma County Wildlife Rescue in Santa Rosa and the San Diego Humane Society’s facility in Ramona.

The South Lake Tahoe facility plays an outsized role in bear rehabilitation given its decades of experience and its location in the Lake Tahoe Basin, the area being a continual source of human-bear conflicts and bear issues of all kinds – from wildfires to vehicle strikes on busy Lake Tahoe-area roads.

The fortifications to its bear enclosures are just the beginning of several improvements coming to Lake Tahoe Wildlife Care as part of a planned expansion effort.

The facility has met and exceeded a $500,000 matching grant that will fund construction of a new wildlife animal hospital and care unit. The new facility will feature animal hospital services, a neonatal nursery, operating room and recovery rooms, along with other care and treatment spaces needed for a full-service wildlife veterinary hospital, including 24-hour care services. When completed, rescued native wildlife in the Lake Tahoe Basin can be cared for in the region’s first dedicated wildlife animal hospital. Construction is expected to begin in the spring of 2022.

While they can thrill tourists and residents alike with their mere presence, antics and brazen behavior, life is no vacation for the Tahoe Basin’s black bears. They often face many more serious threats to their survival and well-being – traffic, disease, a garbage-filled diet, human conflicts and now wildfire – than many of their wildland counterparts.

That point was driven home recently when veterinarians at the California Department of Fish and Wildlife (CDFW) had to euthanize a year-and-a-half old female bear – one of the “South Shore Four” – released this spring back into the wild after seven months of rehabilitation at Lake Tahoe Wildlife Care (LTWC). The bear arrived at LTWC in September 2020 as a 50-lb. cub suffering a broken leg after being hit by a car on Emerald Bay Road near Eloise Avenue.

Rehabbed alongside three local orphaned bear cubs – two males and one female – the young females were released together last April about 70 miles from South Lake Tahoe.

The one female with the healed hind leg was of particular concern to biologists. The cub’s mother was a known problem bear – raiding garbage cans, breaking into garages and cars – and was thought to be teaching these same behaviors to the cub before the cub was struck by a car and taken to LTWC for rehabilitation.

Outfitted with a GPS tracking collar and a No. 83 blue plastic tag in her left ear, the female bear, weighing some 150-lbs. at that point, headed almost immediately back to South Lake Tahoe, the bear’s collar sending signals from the Freel Peak area. Campers later spotted the bear in the Zephyr Cove area and South Lake Tahoe residents reported seeing the bear in the exact backyard where it was believed to have been born. The bear showed little fear of either cars or people.

Then, on May 24, the bear was found unresponsive, sprawled out on its side at the base of a tree in a residential backyard along Freel Peak Ave., leading to initial speculation that the bear had been struck once again by a vehicle. An emergency visit to a local animal hospital, however, showed no sign of trauma. The bear was returned to LTWC for care and observation.

Although the bear improved after a week, LTWC staff agreed that the bear never recovered fully. Mentally, it seemed like a different bear altogether than the one staff had cared for prior to its April release – mentally dull and lethargic.

In June, the bear was moved yet again – this time to CDFW’s Wildlife Health Lab near Sacramento for further observation and examination by CDFW veterinarians.

Given the mental dullness and its lack of fear around people, biologists and veterinarians suspected encephalitis – or inflammation of the brain – as the root cause of the bear’s problems. The neurological disorder has turned up increasingly in the Lake Tahoe Basin’s black bear population. A cause for this disorder has yet to be identified and currently there are no treatments.

At CDFW’s facilities, the female bear remained unsteady on its feet with an abnormal gait and mental dullness. Showing no signs of physical or mental improvement, the decision was made to euthanize her due to the grave prognosis for a return to normal function and release back to the wild.

A post-mortem examination to determine a cause of the physical and mental abnormalities was inconclusive. The examination showed no evidence of encephalitis or recent physical trauma but did find “degenerative changes in the brainstem.” Additionally, trace amounts of bromethalin were detected, revealing exposure to this neurotoxic rodenticide.

Still, relatively little is known about the potential effects of bromethalin in wildlife, and veterinarians were unable to determine whether it could have caused the degenerative changes in the brain or the physical and mental changes observed when the bear was alive.

CDFW biologists continue to monitor the three remaining “South Shore Four” bears in the wild. These bears are now confronting the latest threats to their survival and well-being – namely, the Caldor and Tamarack fires.
