Fruit-bearing trees are a natural attractant for browsing bears during their hyperphagia period. North Boulder was once an apple orchard and many of its trees remain to this day.

Volunteers with Community Fruit Rescue, a local non-profit, pick apples from overburdened trees in Boulder. One-third of apples are sent to the Wild Animal Sanctuary in Keenesburg, Colo. where they feed captive bears.

Many of Boulder's bears spend their days consuming trash in the alleyways that border Chautauqua Park and then fall asleep in nearby Columbia Cemetery. But in 2013 the cemetery proved to be a dangerous place to rest—two bears were euthanized there due to the cemetery's close proximity to Flatirons Elementary School.

In early September 2013, a 200-pound male black bear was put down near Columbia Cemetery after forcing a lockdown at Flatirons Elementary.

Margaret Isenhart pushes her goats into her goathouse in Boulder, Colo. on a late October evening. A rogue bear attacked and killed two of her goats, Tweedle-Dee and Frosty, that fall, while a third, She-Devil, seemingly died of fright.

A trap baited with marshmallows and maple syrup awaits the rogue bear that attacked two of Margaret Isenhart's goats in late October. According to Kristin Cannon, Colorado Parks and Wildlife district manager, the bear was never caught.

Margaret Isenhart points to a pile of old tires to show where she saw found the body of Tweedle-Dee, the second goat suspected to have been killed by the bear.

"The dogs were screaming bloody murder," says Margaret Isenhart of her three dogs on the third night the bear attacked her goats. "And the peacocks were upset."

Margaret Isenhart has lived at her farm off 75th and Arapahoe for 47 years and says she's never had any issues with bears before. "I keep thinking this is a sign I need to sell the place. But I'm not going to. Not yet."
