7 Incredible Tools The Native Americans Crafted From Tree Bark

7 Survival Items The Native Americans Made From Tree Bark


Most of us see little use for bark. We peel it before we build with it, we trim it off before smoking fish or game, and we generally don’t see much value in it as firewood or a dependable heat source.


Native people, though, had a much different viewpoint. They used bark from many trees as a resource for numerous solutions, but there’s a trick to working with this material.


Paper birch is the bark of choice for bark crafters, and the Ojibway took barkcraft to a new level thanks to the fact that birch grew everywhere they lived. Other tribes had to make-do with stiffer and less pliable resources, although slippery elm, willow and aspen offered workable solutions.


Harvesting Bark


Be careful with living, green trees. If you remove too much bark, you will potentially kill the tree. In fact, if you cut the bark from a tree around its circumference, it will be dead in weeks, if not months. Native peoples would sometime “girdle” a tree. This involved removing bark around the full circumference of the tree; this was a designed action and they knew that the following year the tree would be dead. Often, a large fire was started at the base and stone axes were used to cut into the weakened and charred wood until repeated fires and chopping felled the tree.

Even a dead birch tree will provide a strong and pliable source of bark. If you come across a dead-fall birch, harvest the bark to your heart’s content. If you’re desperate and only have access to live trees, limit your cuts and stripping to half of the tree if you can. That will at least give it a fighting chance for recovery.


You may be wondering: Why is bark so important to a tree? The inner bark or “xylem” is essentially the circulatory system for any tree. Water and nutrients are delivered to the tree from the roots to its leaves by this circulation. That’s why a “girdled” tree will soon die. When its only source of water and nutrients is cut off, the tree has no options for survival.


Pre-Treating Bark


There are a few steps to making any bark more workable. Some tree bark, like the slippery elm, requires a bit of scraping of the outer bark to make the piece more pliable. Birch is naturally flexible, but it will be curved when first harvested. Native Americans flattened the birch bark on the ground with the curved side down and weighted it with stones. The moisture in the ground and the weight of the stones eventually flattened the bark.


Another key step is to soak the bark in hot water before working with it. This also adds some flexibility, and it helps to keep the bark from splitting when it’s folded or shaped.


Many bark creations were sewn at the seams with cordage or strips of leather to re-enforce items like baskets and bowls. If the object needed to hold water, the seams were sealed with pine pitch.


Let’s take a look at items the Native Americans made from bark:


1. Cup


One of the easiest and most common uses for bark was for a ladle or drinking cup.  A circle of birch bark was cut and a triangular fold was made from the center to the edge. This fold was then overlapped to form a cone. The creased bark was held in place with a stick with a split in it, and the fact that the bark was not cut made it water tight to either scoop water from a spring, or to simply drink it as a cup.


2. Bowl


This same approach was used with a wider circle of birch bark or slippery elm to make bowls supported by rocks around the side, or a hat that would shade you from the sun or protect you from the rain.

3. Pot


The bowl concept also can allow you to cook with a bark cooking pot. Hot stones were picked from a fire with two sticks much like chop sticks, and the stones were swirled in the water until the water actually started to boil.


But be careful with hot rocks. A rock from a river may appear nice and smooth, but many of them contain moisture in their cracks and crevices and can explode and shatter in the fire. Igneous rocks like granite or basalt are the best because they are less likely to be porous and allow water to seep in.


4. Sunglasses


“Sunglasses” are another option, with a piece of bark cut about six inches wide and two inches in height. You may doubt the need for sunglasses, but in winter, snow-blindness is a serious problem, as sunlight reflects off forests and fields of snow. These sunglasses, though, did not contain any glass or plastic. A couple of sticks were used to support the bark strip over the ears like a regular pair of sunglasses, and two crosses in the shape of a plus sign (+) were cut into the bark at eye level.

A semi-circular cut was made to fit over the bridge of the nose. The size of the crosses was usually a half-inch long both up and across, and the slit was about an eighth of an inch wide. You look at the world through the slit, which allows less light and protects your eyes. This was actually an Eskimo invention.


5. Backpack


A backpack is also easy to make with a long piece of bark about three feet in length and a foot and a half wide. The bark was folded over, and the seams on either side were sown together with cordage or long strips of leather. Holes were poked first and the cordage or leather simply woven through. Straps from cordage or leather were attached and reinforced with more lacing. and everything from personal items to harvested plants, fruits and vegetables could be carried with ease.


6. Candle lantern


A curved piece of birch bark, wrapped and held in place at the base around a circle of sawn wood creates a wind block and reflector for a candle lantern in a fixed camp. Be careful using this indoors. Birch bark is highly flammable, which makes it great tinder, but not something you want to burst into flames in a cabin.


7. Torch


A simple torch is easy to improvise, with strips of birch bark held in place by a slit in a long branch. Additional strips of bark can be added as the birch burns; it actually gives off a good amount of light for a long time.


Final thoughts


All Native American tribes crafted canoes from birch, but that’s something that’s a bit beyond my expertise, although I’ve had success making small-scale toy canoes from birch bark, and my kids and grandkids still play with them. Maybe someday I’ll see if I can scale it up and actually make a birch bark canoe, but I’ll definitely be testing it in very shallow water.

7 Little-Noticed Ways to Use Tree Bark for Survival

If you find yourself in a survival situation in the woods, you’re basically standing in a goldmine of potential resources, all of which are literally at your fingertips along the trunks of nearby trees. Knowing just how versatile tree bark can be might just save your life.


1. Cordage


Tree bark, specifically long strips of inner bark, can be wrapped or braided together to create durable and flexible cordage quickly. Simply cut away the flaky outer bark from a section of the tree, and then begin to peel the inner bark away in long strips. Don’t remove more than one-fourth of the bark around the tree, or the tree might not be able to survive. Longer cuts top to bottom are better than wider cuts going further around the tree.


Good tree species to try include cedar, aspen, basswood/linden, maple or willow.


2. Food


While eating tree bark may seem to be an act of desperation, it’s actually a traditional food in some cultures, eaten for its distinctive flavor even in times of plenty. The indigenous Sami people of northern Sweden use the inner bark of birch trees, first drying and then grinding it into a flour for baked goods.  It’s described as giving a “sweet woody aroma” to baked goods, and actually boasts 1,000-1,200 calories per kilogram.

Pine bark is also used by northern Scandinavian people for food, and rather than being relegated to a famine food, there is historical evidence that rich, well-off families collected the largest amounts of the nutrient rich inner bark. While it is also commonly ground into flour, it can be eaten fresh during harvest and has a mild sweetness and texture similar to coconut meat. As an added bonus, it contains plenty of vitamin C to help ward off scurvy during the wintertime.


3. Medicine


While the medicinal properties of willow bark, the native source of Tylenol, are well-known, there are many other tree species that also have medicinal bark.


Witch hazel extract is an antibacterial wash made by cooking thin witch hazel branches on a slow simmer for many hours to extract the compounds in the wood and bark.


Beech bark tea is used to treat lung problems and was once used to treat illnesses as significant as tuberculosis. Even common apple tree bark has medicinal properties when used to treat fevers and diarrhea.

4. Basketry


The inner bark of basswood, elm, hickory, willow, ash and maple trees all can be used to weave sturdy and long-lasting basketry. Strip off the outer bark, and then peel the inner bark into long flexible strips. Roll up the bark strips for storage until you’re ready to begin working, and then rehydrate them with warm water to make them more workable before beginning to weave your basket.


5. Fire-starting

Most devoted campers know that the outer bark from birch trees makes excellent fire-starting material.  It peels easily from the trees without harming them and is full of flammable resin that ignites easily.  Pine bark from dead pine trees also makes great tinder because of its flammable resin.


6. Cooking


Tree bark, especially from trees with flexible bark that comes off in large sheets, can be formed into cooking vessels and used to make just about any food you want. Well-moistened birch bark sheets can be used to create an impromptu wok for cooking over hot coals. Let the fire burn down to a thick layer of very hot coals, and then cover with ash to create a barrier. Place the well-moistened birch bark on top and cook your food on the clean hot surface.


Tree bark containers also were traditionally used for boiling maple sap into syrup, as well as storing the finished maple syrup for long periods of time (up to a year).


7. Bedding


In a survival situation, it’s essential to insulate yourself from the cold ground while sleeping to prevent hypothermia, even in relatively mild climates. Tree bark is an excellent insulator because it can be peeled in large sheets that can be flattened to create a smooth and comfortable surface. The corky nature of many species of bark also creates a natural insulation.
