The California Department of Fish and Wildlife (CDFW) has increased its use of GPS technology to better understand the outcomes of black bears released from wildlife rehabilitation facilities.

This year marks the first time that CDFW is tracking with GPS collars all bears released back into the wild after care from the four wildlife rehabilitation centers permitted to care for black bears in California.

It’s a way to track the bears’ behavior and movements and see how they are faring in the wild. CDFW human-wildlife conflict specialists might also use the GPS information to intercept a bear approaching a neighborhood or community and redirect it back to wild habitat.

Among the GPS-tracked, rehabbed bears released in 2023 were two orphaned cubs from Tulare County. CDFW cameras were on scene to capture the final moments of their care at the San Diego Humane Society’s Ramona Campus and the return of one of the bears to its home in the woods of Tulare County.

Now that the snow has sufficiently melted and spring has sprung, the California Department of Fish and Wildlife (CDFW) has resumed Trap-Tag-Haze efforts in the Lake Tahoe Basin.

Since 2017, CDFW has caught, tagged, collected DNA and released 36 bears as part of its Trap-Tag-Haze bear research and management efforts in the Basin.

This spring, CDFW will focus initially on the South Lake Tahoe area, where a few different bears have broken into homes since the summer of 2021. Although reports have slowed, these bears have caused significant property damage throughout the neighborhood known as the Tahoe Keys.

If the large bear that recently garnered significant media attention is trapped, it will be evaluated by CDFW veterinarians for release into the wild. A release site in appropriate bear habitat has already been identified that should provide the bear plenty of habitat to transition to wild bear behaviors. The bear will be monitored with a satellite tracking collar that will help determine if the management effort is effective.

All other bears captured will be ear-tagged and hazed upon release (loudly chased to provide a negative association with humans and habituated behavior).

DNA evidence collected through Trap-Tag-Haze efforts already has shown interesting family relatedness among bears displaying similar activity. In other words, mother bears are likely teaching negative and nuisance behaviors to their offspring.

Some monitored bears have successfully acclimated to wild habitats outside of town while others have returned and continued to exhibit habituated behaviors, which means associating people, homes, cars, campgrounds, coolers and the like as sources of food.

Following the South Lake Tahoe Trap-Tag-Haze efforts, CDFW will move the operation to the western and northern sides of the Basin. The video below further explains CDFW’s innovative Trap-Tag-Haze program.

Incidents with black bears in the Tahoe Keys area of South Lake Tahoe are getting national and international attention. Tahoe is natural bear habitat, and the California Department of Fish and Wildlife (CDFW) takes each of these periodic incidents seriously.

CDFW is enlisting the community’s support and cooperation to conduct a thorough effort to keep bears away from people and homes and— when needed— to trap, tag and work to relocate habituated bears. All of these efforts are focused on keeping residents safe, and enabling safe and healthy conditions for these bears.

While recent incidents of bears invading homes were originally thought to be a single bear, DNA evidence collected from the most recent incident as well as prior incidents over the past several months prove that at least three bears were responsible for breaking into numerous residences. The most recent incident was attributed to a large black bear (the same bear the public is calling “Hank”) likely based on visual observation. Considering new evidence suggesting multiple bears are responsible for recent incidents, CDFW will work in coming weeks and months to trap bears in the South Lake Tahoe area, tag them, collect evidence for genetic analysis, and then release them into suitable habitat. During this effort, CDFW will gather information and learn from scientific analysis to help inform and refine our bear management in the Lake Tahoe Basin. CDFW is not going to euthanize any bears that are trapped during this effort.

Identifying bears simply by their visible, physical characteristics can lead to misidentifying bears and therefore confusing management efforts. The genetic information gleaned from our effort in the South Lake Tahoe area will assist CDFW by expanding its database of bear genetics and hopefully preventing future misidentification of bears.

For this effort to be successful, CDFW will need ample community support. First, CDFW requests the Tahoe Keys and surrounding communities to collaborate on the placement of traps to protect both residents and the bears. CDFW must have approval to place traps on private property and will need that access for this effort to work. Additionally, for traps to work, they must be left alone and not vandalized or harmed in any way.

It is critical that Tahoe Keys residents and everyone who lives or recreates in the Lake Tahoe Basin carefully store food and trash. Increasingly, CDFW is involved in bear/human conflicts that could have been avoided by people taking a few simple actions. Bears are primarily scent-driven when seeking food. Improperly stored human food and trash are likely attracting bears into this neighborhood. We all need to take all precautions to store food and trash properly to protect ourselves, our neighbors and local bears. Additional information and resources are available at CDFW’s Keep Me Wild: Black Bear web page.

CDFW has been reaching out to local governments and homeowners’ associations to educate residents and visitors of Lake Tahoe about “bear-proofing” homes, including installation of bear-proof garbage receptacles. CDFW will continue this important outreach and is exploring options to ensure that homes in the Lake Tahoe Basin are equipped with these receptacles.

CDFW’s new bear policy highlights the importance of these actions, and establishes a clear process to address each unique situation with bear/human conflict as it arises. It takes an adaptive management approach that relies on community partnerships.

By working together, these efforts to protect residents and bears can be successful. We appreciate everyone’s engagement as we work through this situation in a thoughtful, science-based, transparent manner.

When California Department of Fish and Wildlife (CDFW) biologists recovered a GPS tracking collar deep within the Stanislaus National Forest in April, they suspected that was the final chapter in the saga of the “Kings Beach Bear.”

Also known as the “Safeway Bear” or the “Chevron Bear,” the big, male black bear made headlines in 2020 (YouTube) by entering local business on Lake Tahoe’s North Shore – including a Safeway and Chevron convenience store – rummaging for food and crashing Kings Beach get-togethers, helping itself to birthday cake and other treats and prompting widespread concern.

CDFW trapped the problem bear in September 2020, affixed identifying ear tags – a metal tag in its left ear numbered 1217 and a plastic orange tag in its right ear numbered 1274 – along with the GPS tracking collar and ultimately released the bear into remote wild habitat in El Dorado County.

With the bear’s tracking collar recovered last spring – with no sign or evidence of the bear otherwise – two potential outcomes were discussed. In a best-case scenario, the bear successfully transitioned to a natural diet and life in the wild, losing winter weight that allowed the GPS collar to come free. In a worse-case scenario, the old bear – estimated at more than 15 years old – was unable to adjust, lost weight and died.

The ultimate fate of the Kings Beach Bear proved much more tragic and traumatic.

In early August, a CDFW biologist and wildlife officer responded to calls of a large black bear shot and killed at a campground in Alpine County near Hermit Valley.

A large family with many small children was camping in the area when a large black bear approached their campsite repeatedly during the early evening and late hours of the night. Multiple attempts to haze the bear and shoo it away proved unsuccessful.

The campsite was clean and the family had properly stored and secured their food and garbage. Fearing for its safety, the family shot and killed the bear when it approached their campsite yet again – and reported the shooting to officials. The family was distraught when CDFW showed up to investigate.

At the scene, CDFW officials saw the 1274 orange tag in the bear’s right ear, identifying it unmistakably as the Kings Beach Bear. The bear – once weighing more than 500 pounds – was a shell of its former self, completely emaciated, its teeth rotten.

As one CDFW biologist later said, “Ultimately, the actions of the shooter was the most humane outcome for this bear.”

CDFW wildlife officers ruled the shooting justified. And CDFW biologists now have more empirical evidence and a rather traumatic case study about the ability of human food-conditioned bears to successfully transition to life in the wild.

In wildlife work, happy endings, feel-good stories and grand conclusions can be elusive.

Such is the case with the “Kings Beach Bear,” the big black bear that made national news in 2020 by entering local businesses on Lake Tahoe’s North Shore in search of food and crashing Kings Beach get-togethers, sending partygoers fleeing and helping itself to birthday cake and other treats. In the end, researchers may never know the ultimate fate of the animal also known as the “Safeway Bear” or the “Chevron Bear” for the Tahoe businesses it so brazenly frequented.

California Department of Fish and Wildlife (CDFW) scientists recovered the bear’s GPS tracking collar April 6 deep within the Stanislaus National Forest, near Beardsley Reservoir in Tuolumne County. The bear’s collar was completely intact, clasped closed and lying on the forest floor about 27 air miles southwest of CDFW’s Leek Springs Ecological Reserve in El Dorado County, where the bear was originally released Sept. 6, 2020.

“The collar had been sending satellite signals from the same location since January, but because of the snowpack, we couldn’t access it until April,” said Shelly Blair, CDFW’s unit wildlife biologist for Alpine and El Dorado counties. “We think the bear slipped the collar months before we could get to it. Originally, we thought the bear was denning in that location, but the site where we recovered the collar did not have any denning areas that we could find.”

Earlier collar signals showed the bear made a successful crossing of Highway 88 and passed through the Mokelumne River drainage above Salt Springs Reservoir into Amador County in October.

While bear scat and bear prints were found near the collar recovery site, no carcass or other evidence turned up indicating the current state of the bear. CDFW scientists suspect the collar – a modified, refurbished elk tracking collar – came free as the bear lost winter weight in the wild – removed from a diet of human food and garbage around Lake Tahoe.

CDFW trapped the Kings Beach bear that first week in September 2020. A veterinary exam revealed an old – more than 15 years old – male bear weighing a whopping 512 pounds with bad teeth and a poorly healed injury on its left hind foot. Due to its old age and lack of available space, placement in a permanent wildlife facility or zoo was not an option. The bear was taken to a large expanse of wild habitat on CDFW property in El Dorado County and released. In addition to a GPS tracking collar, the bear was outfitted with two identifying ear tags – a metal tag in its left ear numbered 1217 and a plastic orange tag in its right ear numbered 1274.

Although the bear’s whereabouts are unknown, CDFW does know that the bear stayed in the wild – for a few months at least before shedding its tracking collar. As far as CDFW is aware, the old bear has never returned to Lake Tahoe's North Shore where it caused such a stir last year and earned its celebrity status.
