Rocky Mountain National Park is warning visitors to secure hammocks, ropes, and other loose materials after several elk and moose became entangled in objects left behind in the park.

Park officials recently responded to multiple incidents involving large wildlife caught in human-made materials, including a moose tangled in hammock fabric and ropes and a bull elk caught in metal wire. Rangers and biologists were able to locate and assist both animals, but wildlife managers say finding distressed animals can be difficult.

The incidents highlight a preventable danger for wildlife in one of Colorado’s most popular national parks, particularly during the fall elk rut.

Hammocks and Wires Pose Risks to Wildlife

According to Rocky Mountain National Park, a variety of everyday items can create entanglement hazards for wildlife. Hammocks, clotheslines, fishing gear, lawn decorations, and holiday lights can all pose risks to animals moving through the park and nearby communities.

Large antlers can make the problem especially dangerous for male elk and moose. When animals become caught in ropes, wires, or fabric, their movements can tighten the materials around their bodies or antlers, potentially leaving them unable to free themselves.

Although park wildlife managers work to help animals in distress, locating an entangled animal is not always easy. The recent incidents had positive outcomes because park rangers and biologists were able to find the animals and intervene.

Fall Elk Rut Can Increase Entanglement Risks

Entanglements can happen throughout the year, but Rocky Mountain National Park officials say they can be particularly prevalent during the fall elk rut, when elk are especially active.

During this period, bull elk spend more time moving around, competing for mates, and displaying their large antlers. That increased activity can put them at greater risk of becoming caught in objects left in their surroundings.

Park officials are asking visitors and nearby residents to take simple preventative steps to protect wildlife. Hammocks, clotheslines, and similar items should be stored when they are not in use, while other materials that could snag antlers or limbs should be secured or removed.

Anyone who spots an entangled animal inside Rocky Mountain National Park should notify a park ranger by calling the park’s Information Office at 970-586-1206.
