Can Storing Food High in Trees Be Effective Against Bears?

Physical Barriers are Key

When it comes to bear-proofing food, relying on storing it high in trees is not sufficient. Trees are not an impenetrable barrier for bears, especially those like grizzly bears, which are excellent climbers. In fact, bears can easily climb trees with a diameter of 12 inches or more. To be effective, physical barriers such as bear-resistant containers or electric fencing are necessary to prevent bears from accessing food.

Electric Fencing: A Viable Alternative

Electric fencing is a practical and effective solution for keeping bears out of food storage areas. A fence with a height of at least 4 feet and a voltage of 3,000 to 4,000 volts can be an effective deterrent. The fence should be designed with a self-closure feature to prevent bears from pushing the fence open. When choosing an electric fence, consider a system that is specifically designed for bear protection and follows the manufacturer’s installation guidelines.

Combining Barriers for Maximum Protection

For maximum protection against bears, it’s best to combine physical barriers with other methods such as removing attractants, securing trash, and keeping a clean campsite. This multi-layered approach can significantly reduce the likelihood of encounters with bears. For example, storing food in a bear-resistant container and keeping it at least 100 yards away from your campsite can help prevent bears from associating humans with food.
