Bear Naked Truth

Caldor Fire evacuees returning to the South Lake and West Shore areas of Lake Tahoe should be aware that bears have been seeking out human food sources during the evacuation and taking advantage of the lack of human presence. As you approach your residence, look and listen carefully for signs that a bear has been or is in your home. If a bear is in your home, call 911. Do not attempt to chase it out yourself. Your safety is your responsibility!

The California Department of Fish and Wildlife (CDFW) encourages residents to make repairs to damage caused by bears as soon as possible. Easy access and a food reward encourages bears to keep coming back looking for more. Never leave food or water out for bears. It is illegal, for one, and can lead to escalating problem behaviors such as break-ins and human-bear contact that may result in death of that bear.

The following CDFW images show some of the additional property damage caused by black bears in South Lake Tahoe during the Caldor Fire evacuation.

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.

The California Department of Fish and Wildlife (CDFW) licenses and partners with nearly 100 private wildlife rehabilitation facilities around the state that provide important care, shelter and veterinary services to injured, orphaned and other displaced wildlife of all kinds.

What happens to these animals upon their recovery and release back into the wild often remains a mystery. That’s true even at the only two rehabilitation facilities licensed in California to work with black bears: The San Diego Humane Society’s Ramona Campus in Southern California and Lake Tahoe Wildlife Care in South Lake Tahoe.

While the rehabilitated bears are almost always outfitted with an identifying ear tag or two prior to release, a feel-good video of the bears fleeing a portable trap on their way to freedom is often the last time biologists and wildlife rehabbers ever see them.

With a second chance at life in the wild, do the bears revel in their newfound freedom and stay as far away from people as possible and successfully transition to natural food sources? Or, after months of being cared for and closely watched at a rehabilitation facility, are the bears more comfortable around people, seeking out the nearest rural communities for the easy access to human food and garbage they can often supply? Do bears kept together in a rehabilitation facility and released together stay together in the wild? If so, for how long?

These are among the questions CDFW wildlife biologists are seeking answers to with the recent release of the “South Shore Four” – four young black bears, two males and two females, rehabbing together the past year at Lake Tahoe Wildlife Care where they arrived as young-of-the-year cubs. Three of the four were orphaned when their two mothers were hit and killed by cars – one of the female cubs suffering a broken leg from a vehicle strike.

Fully recovered, weighing between 150 and 190 pounds each and old enough to survive on their own, the “South Shore Four” were released into a nearby national forest last month, two bears at a time. Three of the four cubs were fitted with GPS tracking collars that will alert biologists to their whereabouts four times a day if canopy cover allows. Biologists also receive a mortality signal 12 hours after no movement so that recovery and cause of death can be determined.

“We’re hoping to understand their movements directly after release, whether or not the ones that were released together stay together, the distances they travel and where they’re going,” said Shelly Blair, CDFW’s wildlife biologist for Alpine and El Dorado counties. “This is essential information to monitor the after-effects of almost a year in captivity and where they go. If they’re moving toward trouble – a campground or a community – we’ll be able to see that and get ahead of it if possible.”

GPS-tracking collars are an important research tool for wildlife biologists but also something of a precious commodity that cost between $800 and $2,000 each.

The collars are fastened around the bears’ necks with surgical tubing that will expand as they grow. After a few months of exposure to the elements, the tubing will deteriorate, and the collars will fall off to be recovered later. At that point, the South Shore Four’s research contributions will be short and likely complete, but will yield valuable information about the bear rehabilitation program and help improve CDFW's efforts to ensure the best possible outcome for these animals to be successful wild bears.
