The summer of 2009 saw several potentially dangerous situations, particularly in the Ocala National Forest, and all three national forests have issued regulations requiring food to be hung or stored in a bear-proof container. While damage thus far has been limited to personal property, backpackers can help prevent bears from becoming habituated to humans by properly hanging their food and other bear attractants. Not only will it increase your chances of finishing your hike without a trip off the trail to a grocery, it will also increase the bears’ chances of survival. Bear bagging will also keep your stuff safe from other forest critters such as raccoons, squirrels, and hungry hunting dogs. While the instructions below refer to your "food" bag, note that you should include anything with a strong odor that might attract bears. This includes toothpaste, soap, shampoo, etc.
Proper food hanging for black bears requires that your food bag hang a minimum of 10’ off the ground and a minimum of 4 feet out from tree trunks and major limbs. So start your search for the perfect bear bag spot by looking for a tree with a limb 15-20 feet off the ground that is strong enough to hold the weight of your food bag, but light enough that it won’t support the weight of a bear cub. Also make sure there are no adjacent trees or limbs that animals could use to get close to your hanging bag.
There are at least 4 methods of hanging a bear bag, and many variations on these 4 can be found on the Internet. Most tell you to use a rock, but since rocks are hard to come by in Florida, my instructions substitute a small stuff sack that you can fill with a handful or two of sand on site. None of these methods require a lot of extra equipment or added weight, although it can take practice to perfect a technique that works for you.
All of these methods require:
• A water-proof bag for your food — sil-nylon or coated nylon is best. Look for the kind that has a strap on the bottom and a drawstring on the top. You will actually hang the bag by the strap so the opening is on the bottom. This helps tremendously if it rains during the night.
• At least 50 feet of line — Spectra/Dyneema works great because it doesn’t tangle and is very abrasion-resistant, but any smooth line will work. I like 1/4-inch braided nylon cord. Rough line, like the cheap and frequently recommended parachute cord, may get caught in tree bark making it difficult to retrieve.
• A small stuff sack to hold a handful of sand. I use my tent stake bag.
• 1 or 2 mini-carabiners — the type you would buy for a keychain will do.
