Relocating ‘nuisance bears’ may do more harm than good, UF study shows

GAINESVILLE, Fla. — For decades, state wildlife officials have been trapping and relocating so-called “nuisance bears” that get too close to humans.

But a new University of Florida study shows the policy may merit a second look.

“No one had any idea, when we move these bears, what becomes of them,” said Kim Annis, the Institute of Food and Agricultural Sciences graduate student who presented her findings this month at the annual Eastern Black Bear workshop in West Virginia. “So the object of all this was — is relocating these bears doing what the state thinks it does?”

According to Annis’ study, done in conjunction with the Florida Fish and Wildlife Conservation Commission (FWC), the widely held public perception that relocating problem bears means they scamper into the forest and live happily ever after isn’t entirely accurate.

Nuisance bears tear up campsites, get into people’s garbage, drink out of swimming pools, eat farmers’ chickens or generally get too close for human comfort.

Annis and officials from FWC’s Florida Wildlife Research Institute put radio-tracking collars on 41 such bears that were being relocated from nine Florida counties to the Ocala National Forest in North Central Florida. She followed them, on foot and by plane, from May 2004 through December 2006.

Eight bears died during the study. One was euthanized after repeatedly trying to enter a home. One died of natural causes. Two were hit by cars. Another died in a forest fire. Three were illegally killed.

While the mortality rate for the relocated bears wasn’t radically different from typical rates for Florida black bears, humans were directly or indirectly responsible for seven of the eight deaths.

And relocating the bears didn’t always stop the bad behavior.

Nearly half the bears engaged in at least one instance of nuisance behavior even after being moved—and 34 percent of them did so more than once.

UF wildlife ecology and conservation professor Mel Sunquist, who supervised Annis’ work, said it appears that if you move the bears far enough away, they’re less inclined to return to their home turf.

But in Florida, as development has boomed, bear habitat has dwindled, so with only six large habitats left, moving every nuisance bear far enough away is expensive and inconvenient.

“If you are in someplace like Montana, you can cart them off, turn them loose and never see them again,” he said. “But we don’t have that luxury here.”

Annis noted that four of the bears covered a lot of ground, traversing up to 541 miles and crossing busy highways repeatedly.

Walt McCown, an FWC bear research biologist, said the mileage some bears logged was a bit of a surprise.

“That was my budget (Annis) was eating up, driving around and flying around, looking for them,” he joked. FWC resources were used for much of the study, including a small plane, fuel and personnel to help trap and drug the bears.

Black bears can live close to humans and are rarely aggressive, McCown said. Nuisance behavior is almost always a result of the bears looking for food.

And find food they do, especially around humans, Annis said.

Annis found several bears that were much fatter than they would be if they were living off the forest — and not people’s backyards. One young male that should’ve weighed about 90 pounds was a portly 275, she said.

“In the fall, a bear can eat 20 hours a day and needs 20,000 calories – but why do that when they can get that from a bird feeder in 20 minutes?” she said.

Though there are pockets of black bears in eight forests around the state, by far, the most complaints come from residents who live near the 430,000-acre Ocala National Forest.

Of 1,600 nuisance-bear calls to FWC in 2004, more than half were from that area, McCown said.

Educating the public about ways to peacefully coexist with their large, furry neighbors may be a better option than spending thousands each year to move or euthanize them, the study suggests.

The Florida black bear has been a threatened species since 1974, when there were between 500 and 1,000 bears in the state. The state’s bear population is now believed to be between 2,200 and 3,000, with about 1,100 in the Ocala National Forest and the St. Johns area, she said.

Bear hunting was banned statewide in 1994.
