Black Bear Management

“The black bear is the symbol of the Smokies,” says wildlife biologist Bill Stiver. Looking around Gatlinburg, Tennessee and other towns that border the national park, this seems undeniable. From black bear t-shirts to carved bear-shaped logs, representations of this charismatic bear are everywhere. In the past, many people expected to find the same bear in the park that they’d seen in the stores: a grinning, shaggy, friendly animal. Visitors came to the Smokies—and other national parks, from Yellowstone to Yosemite— not only to see wildlife, but to get up close and feed them. This resulted in some great photos, but it also led to hundreds of conflicts resulting in the death of many bears and injuries to people.

The current bear population estimate—1,500 to 1,600 bears—is the largest ever recorded here, yet you may be less likely to glimpse one than ever before. The reason is that more bears are wild. Over the years, the number of “nuisance bears,” (animals that bother or are aggressive toward humans) has dropped significantly. Thoughtful and successful bear management from wildlife staff—along with help from park maintenance, law enforcement, resource education, and visitors like you—has made the co-existence of humans and bears possible.

In addition to better management, we also know much more about the black bears themselves, due in large part to professors such as Dr. Mike Pelton (now retired) and Dr. Frank van Manen, and many graduate researchers at the University of Tennessee. These researchers have conducted bear population—and more recently, genetic—studies in the Smokies since 1968.

 

As seen in this photo from the 1950s, 5-14 people on average were bitten, scratched, or otherwise harmed by bears annually in the Smokies.

Keeping Our Bears Wild

In the early days of Great Smoky Mountains National Park, rangers gauged bear management success by the number of visitors injured each year. People bitten by bears weren’t the only ones suffering from this contact: bears learned to connect humans to food, and approached people in campgrounds and picnic areas. In some years, dozens of “nuisance” bears that had invaded human space were moved or even killed.

Gradually, as attitudes throughout the park service changed, it became clear that management needed to shift from being reactive (managing bears after a problem) to proactive (managing bears and people prior to problems). While it was easy to blame nuisance bears on visitors feeding them (and many in the Smokies still did, often through chain link fences installed on backcountry shelters), the issue was bigger than that.

Other factors in bear problems included unclear rules about (or consequences for) feeding bears, trash piled next to overfilled trash cans, food scraps left in fire rings, and visitors who left picnic goodies unattended on tables. This wasn’t acceptable to managers; as biologist Kim Delozier said, “If we have to move or kill a bear, we’ve failed” somewhere along the line in not preparing for possible problems. Wildlife management in the Smokies was about to change.

 

It used to be common to see black bears such as this one at Chimneys Picnic Area feeding on human food.

Success Story at Chimneys Picnic Area

For wildlife managers such as Kim Delozier, an evening drive to the Chimneys Picnic Area to deal with a nuisance bear became all too common. Visitors started lining up lawn chairs at dusk to watch bears pouring over the hillside to feed off of picnic tables and out of trash cans.

In just 3 years at Chimneys, from 1988-1990, wildlife managers handled (captured) 24 different bears—8 per year, on average—and relocated bears 35 times—often the same bears over and over. During that same period, managers had to euthanize 3 bears that had become aggressive toward humans. One of these bears seriously attacked a visitor, who had to be hospitalized for 10 days.

 

New educational tools such as this helped visitors know what to do to keep bears--and themselves--safe.

Wildlife biologists saw that it wasn’t only bear behavior they had to change: they needed the buy-in from visitors who were used to—and loved—feeding and watching the bears, and they needed logistical support from within the Park itself. Working together, they hoped, would not only control bears that were already problems, but prevent wild bears from associating humans and human areas with easy food.

The plan that managers began in 1991 at Chimneys included

• enforcing a strict closing time (8:00 p.m.) at Chimneys picnic area so workers could clean picnic leftovers and prevent the bears that came from finding food or garbage (“re-training” the bears)
• shifting maintenance staff schedules from a morning shift to an evening shift so they could clean up after lunch & dinner picnics
• enlisting picnickers’ support with information signs about managing food and garbage to protect bears
• installing larger trash containers (3-yard dumpsters) with bear-proof lids and latches, and emptying them regularly
• beginning an intensive education campaign park-wide to teach visitors about black bears that included a black bear folio (available at the Visitor Center), two videos—Learning to Live with Bears, by Bill Landry, and Bear 75: A matter of territory, about one nuisance bear that had to be relocated out of the Park numerous times and was eventually killed by a poacher. Park employees also added information at the Visitor Center desks and to the website educating people about what to do if they encountered a bear.

• aggressively managing “night active” bears by capturing & releasing them on site so they maintained their natural fear of and aversion to people

 

After proactive management began in 1991, the number of bears handled and moved per year at Chimneys Picnic Area decreased dramatically.

The results of proactive management were that fewer bears had to be moved or killed, and fewer visitors were injured. At Chimneys, the improvements in bear and human safety were dramatic. In the 17 year period following the new management strategy (1991-2008), managers handled an average of 3 bears per year (about 60 percent fewer bears than before), and only had to relocate 1-2 bears (about 87 percent fewer bears) each year. Managers, maintenance, and other staff implemented many of the new policies park-wide.

The Park also began coordinating with communities outside its borders —Gatlinburg, Cosby, Townsend, Pigeon Forge, Cherokee, and their surrounding developed areas—to reduce bear problems in the entire region. Bears can move easily between the Park and these communities, and as Bill Stiver said, “You can have 10 people in the neighborhood doing the right thing [by not feeding bears], and just one doing the wrong thing. And then you have a nuisance bear.” Many individuals in these communities shared the goals & policies regarding bear-proof garbage cans and zero-tolerance for feeding wildlife.

“Where did all the bears go?” ask many visitors who knew Chimneys and its bears in the 1980s. To wildlife managers, this question at a time when the actual bear population is at historically high levels means that the proactive, preventative management has been successful. “We didn’t move any bears out of Chimneys,” says Bill Stiver. “We just became more proactive [in bear management] and it’s working to keep the bears wild and out of human spaces where people would see them. Overall, we’re trying to manage for wild bears, and wild bears are afraid of people.”

Black Bears and You

Bears depend on responsible decisions by visitors like you to stay safe and healthy. Ninety-eight percent of bears in the park are wild animals that avoid humans: they feed and wander in the forests and grasslands. We glimpse these wild bears playing in streams, munching acorns deep in the forest, or sometimes loping across the fields of Cades Cove. The 2 percent of bears that we consider “nuisance bears” have gradually lost their fear of humans, becoming first “night active” in human areas, and then “day active” nuisance bears that approach people, beg for food, or tear into tents. This process happens as humans enter bears’ territory, leave food unattended in picnic areas or backcountry campsites, and approach bears trying to feed or cross the road.

The sliding scale of bear “badness”
First off, no bear is a “bad” bear. Bears are intelligent, and those that become nuisances have learned—from people—to get food from humans rather than the wild. If they can find food in an environment they deem safe (empty picnic areas or cozy campgrounds at night, or from a friendly handout), they’ll keep doing it, even if they have to be increasingly bossy or aggressive about it.

The way the Park manages bears depends on where the animals are on the scale of wild to food conditioned (approaching people for their food), which managers gauge by the time of day of the bear’s activity and the extent to which the bear approaches humans. Each of the following techniques is an attempt to create a negative (or scary) experience that outweighs the possible positive experience (such as a food reward) that the bear gets from raiding trash cans or going after scraps.

• To discourage a curious, night active bear (often a young bear looking for new territory), they might only need to scare it away to show the bear that it should be afraid of people.
• If the bear persists, managers “catch and release” it, and hope it learns from the negative experience not to go anywhere near humans again. “For a bear, [catch and release] is a negative experience that it remembers,” Bill Stiver said, although bothering the bear isn’t the goal. Managers “work up” the animals that they catch in bear traps, which includes taking vital signs (weight, temperature, heart rate), extracting a pre-molar for aging, putting in an ear tag, and tatooing the bear's belly and under its lip. From this work-up, managers can collect important biological information from them. Sometimes, managers find that these bears are older and have damaged or missing teeth—both a result of eating human food and a cause for them to seek more easy meals. Biologists may send these bears to a university for dental work.

• When “catch and release” doesn’t deter a bear, or if the bear shifts to a “day active” or “nuisance” animal, managers may move it, although they try to avoid this. Moving a bear is disruptive to the animal moved and the bears already living in the new area. It’s also sometimes fatal for the animals, because in trying to return to their homes in the park, bears cross major highways or are killed during hunting seasons.
• The line between nuisance bear activity and truly dangerous actions comes when a bear invades human space: when it tears into a tent or car, when it willingly goes into a building (a house, office building, or restroom), or when it aggressively approaches or attacks and bites people. By the time a bear is day active and aggressive toward humans, it’s too late to move it or try to change its behavior. Managers put these bears to sleep. Luckily, very few bears in the Smokies reach this point.

Bear management is largely human management, say wildlife biologists; most of their work comes in preventing problem bears by enlisting the help of visitors like you, as they did successfully at the Chimneys picnic area.

Nine million people visit the Smokies annually, and most have impeccable manners when it comes to not feeding or approaching bears. However, as Bill Stiver said, even if we have 90 percent cooperation, that’s still almost 1,000,000 people who could start a wild bear on the path to becoming a nuisance bear. You can help by keeping food away from bears wherever you are in the Smokies and simply watching—without approaching or following—bears that you may see in the Park. Rules in the Smokies state that “willfully approaching within 50 yards of a bear or within any distance that results in their disturbance or displacement is prohibited.” It’s not good for you or the bears. Remember: Your actions keep our bears wild and alive.

Keep Bears and Your Family Safe

Keeping human food away from bears is the most important step we can take to keep bears—and ourselves—safe.

When you’re picnicking & hiking:

• Always stay with your food when it’s outside your car—don’t leave a picnic, cooler, bag of trash, or backpack alone!
• Pack it in, pack it out. Throw away all food scraps and wrappers in a bear-proof trash can or dumpster. You can find these at picnic areas, visitor centers, pullouts, and some trailheads
• Make sure grills or fire rings are clear of trash—help a bear out & throw away any litter and food scraps you find, even if you didn’t leave them

When you’re backpacking in or through the park:

• Check Backcountry Information Posters at all permit stations and visitor centers—these list backcountry sites closed due to bear activity, and sites/trails where you should use caution because bears have been active
• When you pack, consider the “smelliness” of your food (and its packaging after the food is gone). Bears have a great sense of smell, and your can of sardines may be irresistible to them for days after you’ve dined

• Consider packing all of your food in one bag inside your pack to contain smells, & to make hanging your food easy
• Camp only at designated sites, where you’ll find bear cables
• USE BEAR CABLES to hang your pack, food, & any other equipment whenever you aren’t using it
• Cook, prepare food, & eat away from your tent/shelter
• Pack it in, pack it out: double-bag all trash in sealed bags, & throw it away when you’re back in civilization
• Make sure fire rings & shelter fireplaces are clear of trash—help a bear out & throw away any litter you find, even if you didn’t leave it

Always report bear activity such as bears approaching people, taking packs, begging for food, or acting aggressively to Park Rangers when you get back from your trip.
