Fears
Loom As Bears Ditch Hibernation During Drought
Bears
are finding it so unseasonably warm in the Sierra Nevada mountain
range this winter that many of them are forgoing
hibernation in
favor of foraging through garbage, bringing them closer to humans and
spelling out trouble for the food chain

Bears
in the Lake Tahoe, Yosemite and beyond usually spend December through
March napping in caves, but residents and visitors have noticed an
increase in bear activity typical of summer months. With temperatures
10 degrees above normal accompanying the
California drought,
bears have found little reason to hibernate -- especially when there
is plentiful food in the Lake Tahoe region.
"In
this weather, you're going to see more of them," Chris Healy of
the Nevada Department of Wildlife told the San Francisco Chronicle.
"They're totally content to hibernate, but if the food's
available, they'll get up and eat."
The
troubling phenomenon has been apparent to residents of the Sierras,
where last week's snowpack measured just 17
percent of normal.
"The
local bears are coming out of hibernation three
months early!"
Tom Loe of Sierra Drifters Guide Service wrote. "I have been
forced for the first time in nearly 20 years here to water my
deciduous trees in a T-shirt -- they are budding!"
Earlier
this month, a bear was caught on film scurrying
across the slopes during
a ski race at Heavenly Mountain Resort. The appearance ended without
any incident, but concerns go beyond possible scuffles with humans.
Wildlife experts warn the bears’ winter presence will only further
exacerbate food and water shortages linked to the drought
and California’s
driest year in recorded history come
spring.
"A
drought basically dries
up the natural food availability and
dries up the water sources, and you get them not only wandering
farther, but often coming to urban areas to fulfill their daily
needs," Jason Holley, a wildlife biologist supervisor for the
California Department of Fish and Wildlife, said of bears facing
shortages of berries or insects to feed on. "We've seen upticks
in drought years. We could be looking at that in the spring.”
