The above represent average numbers, both for the calories required per day, and the amount of food which must be consumed to provide those calories. Variations should be expected. Even so, it is evident that a person attempting to live alone off the land in the wilderness has a serious challenge on his hands. The amount of food required seems absurd, but as Thayer explains: “
If this seems like a high volume of food, that’s because it is. We have sought, developed, cultivated, and become accustomed to calorie-dense foods for so long that most of us have never been without them. We’ve never had to eat food in volumes like this. When you realize that a stick of butter has as many calories as two and a half quarts of blueberries or seven pounds of broccoli, you can see why the innate human desire for calorie-rich, low-fiber food developed.

 

Gathering

The gathering of food has become a great area of teaching for survival and bushcraft instructors. Unfortunately, much of the teachings create a false impression of what it actually takes to feed oneself through gathering of food in the wilderness. As Thayer also noted, many such instructors teach, or imply through their representations that a very small amount of food is needed for a person to sustainably live in the wilderness. Whether the misrepresentations are intentional, or due to lack of knowledge is hard to say, but the results are the same-people fail to realize how much food must be gathered to sustain a person long term.

We have to make a clear distinction between “edible” plants and “food”. Just because something can be eaten, does not mean that it contributes to your caloric requirements in any meaningful way. Many staples of bushcraft teachings, such as dandelions provide virtually no caloric value. You can easily starve to death with a stomach full of such plants. In fact, it is not unlikely that a person may spend more energy gathering edible plants, than the calories he will get from consuming them. To effectively gather food in the wilderness, one has to know not only what is edible, but also what provides meaningful calories.

From the plants available and listed in the above chart, not surprisingly acorns provide the highest nutrition. I imagine it will be similar for other nuts because of the high oil content. If processed correctly, a person can certainly provide enough food for himself using acorn flour. The other plants that are readily available, including the all too popular cattail and burdock roots, are far less than ideal when it comes to providing sufficient calories for a person attempting long term living. Not only would it be difficult to supply yourself with enough of the plant, but consuming such large quantities would be impossible. We should also keep in mind that the plants I have listed here are the ones with relatively high caloric value.

On that subject, Thayer writes with respect to Chris McCandless, “
If he didn’t get any meat, couldn’t he just eat more lingonberries and get all his calories that way? Absolutely not. He would have needed to eat almost three gallons of lingonberries per day. He’d probably be vomiting before finishing the second quart. No matter how many lingonberries were available to him, his body would have only accepted them for a small portion of his caloric requirement. This doesn’t make lingonberries “poisonous”; the same is true of virtually every food, although the appropriate proportions vary… The concept that foods can be eaten only in appropriate quantities is taken so much for granted that, to my knowledge, it has never been given a name in the medical literature. I call it themaximum caloric proportion (MCP). Some foods have a very high MCP, such as milk, meat, and potatoes. They are easily digested and contain few antinutrients or toxins, thus they are suitable as dietary staples. Others, such as cabbage, rhubarb, and raspberries, cannot serve as staple foods and are only suitable to supply small portions of the diet. As one travels north, there tends to be fewer plants with a high MCP; this is why hunter-gatherers from northern latitudes ate meat for the great majority of their calories
.”

As a result, if you can not find the right plants and gather it on a large enough scale, or have simply missed the gathering season, one typically has to resort to meat for the majority of the required calories. So, let’s look at some of what is required in terms of providing sufficient calories through hunting and fishing.

 

Opportunity
Cost of Hunting and Fishing

Before we look at specific examples, it is important to note that when we speak of hunting and fishing, activities which require that you bring specific equipment into the woods, we have to look not only at what you can successfully hunt, but also at the opportunity cost of that equipment. What I mean by that is that for each pound of equipment which you bring with you, you have to forego a pound of some other resource which you could have brought with you instead. Since we are assuming a person who is otherwise prepared for the wilderness, the most immediate opportunity cost is food. For each pound of gear that you bring, you have to leave behind a pound of food. So, when you bring a 7 pound rifle with you, you could have instead left it behind and brought 7 pounds of food. So, when we look at the equipment one may bring for such hunting, we have to see not only if it can get us any food, but also whether the food we can procure with it is more than the food that we could have brought with us had we not brought the equipment.

To complicate things further, we have to look not only at the weight of the food, but more importantly at the caloric content of that food. So, a pound of squirrel meat will give us 752 calories. On the other hand a pound of instant mashed potatoes will give us 1,664 calories. For this post, I will use mashed potatoes as a base line for calorie dense food that could have been brought into the woods. 

 

Fishing

First, let’s look at fishing. Fishing is a good way to procure calories because the equipment required is not heavy, and is relatively reusable. A large net, fishing rod, reel, lures, and a sizable spool of line will only add up to a few pounds. You guys have seen my lightweight fishing kit, which came in under one pound. A more robust and complete kit can be estimated to around 3 pounds. 3 pounds of gear has the opportunity cost (using the above base line numbers) of 4,983 calories, or about day and a half of food at the required 3,300 calories per day. From a simple numbers standpoint, this means that the first day and a half worth of food that you catch will go to offset the weight of the gear (which you brought rather than bringing food). Everything you catch after that is surplus.

The downside of fishing of course is the limited availability of resource reach areas. For example if you are lucky, and are in an area and the right time for a salmon run, as we saw from the above numbers, a single sockeye salmon will give you about two days worth of food. That means that the first salmon would offset the opportunity cost of the fishing gear, and every subsequent one will be pure food value. If you can catch one every two days, you will be able to meet your caloric requirements. The problem of course is that you may be a week late, and not find a single salmon because the run has ended; or, you may be in an area where no such fish is available; or you may be in an area where there is no body of water which carries any sizable fish at all.

Remember, it takes about 3.5 pounds of salmon per day to meet a person’s caloric requirements. If instead of a 7 pounds salmon, you were pulling out 3 ounce sunfish out of the water, the calculations would be very different. At approximately 50 calories per ounce of fish meat, you can do your own math to see how much fish you would need. I remember an episode of Ray Mears Extreme Survival where he caught a small fish while he was in the
Rockies, and prepared it with some plants. It may seem like he has prepared a good dinner, but the reality is that the meal probably contains less that 300 calories, about a tenth of what is needed for the day if we are facing a long terms sustainability situation.

Even with all those considerations however, if you have selected an area close to a sizable body of water for your long term wilderness living situation, fishing is a good way to procure food because of the low weight and reusable nature of the gear, as well as the low amount of energy expenditure required.

 

Hunting

Now, let’s look at hunting as means of procuring food. Obviously, a hunter needs his tools. There are a lot of misconception from people who do not hunt that you can use primitive weapons, constructed in the woods, to effectively hunt. The difficulty of such a task is nearly always underestimated. Thinking that a person can construct a stick bow, or carve a longbow in the woods from an unseasoned piece of wood, and then go hunting with it in an effective manner is wishful thinking. Keep in mind that a hunter with a modern state of the art bow, with modern optics and range finder, will rarely take a shot at over 50 yards. If you are hunting with an improvised bow, lower that range to about 25 yards. Now, go measure out 25 yards and try to think of what it would actually take for you to get to within 25 yards of a deer. Then, think of what accuracy would be needed to hit a squirrel at 10 yards with that same bow. You will quickly gain a healthy appreciation for modern weapons.

Most people who are contemplating long term wilderness living will use some type of firearm, much like Chris McCandless did during his attempt. In recent years, Dave Canterbury, former co-host of Dual Survival, has popularized the single show 12 gauge shotgun as a weapon for long term wilderness living. In this post I will not address any issues regarding whether I believe that to be the best choice, but I will simply use it as a base line for purposes of discussion. A single shot 12 gauge shotgun weighs approximately 6 pounds (
H&R Topper Deluxe with synthetic stock
). Using the number we previously calculated for calories per pound of food which we could have brought into the woods (1,664 cal/lb), we can calculate that a 6 pound shotgun has the opportunity cost in terms of food of 9,984 calories, or about 3 days worth of caloric intake. That would mean that the first three days worth of food which you kill will go to offset the weight of the gun (keeping ammunition weight aside for now). So, if your trip is less that three days, even best case scenario (you being able to successfully kill enough game each day to meet the 3,300 calories per day requirement), you would be better off simply bringing your food with you. That way the availability of food is guaranteed.

For trips longer than three days, the gun would theoretically be the better bet, assuming you can secure enough food with it. So, let’s look at what that would entail. Let’s assume that you are now hunting small game with lightweight shotgun shells (2 3/4 shells with 1 oz load). Each such shell weighs 1.4 oz. So, for each shell fired, we have to add that weight to the opportunity cost, meaning, for each box of shells, we could have simply brought food with us. We than have to see if the numbers work out.

As I was saying, let’s assume you are hunting small game. As we established earlier, it would take 25 squirrels to provide enough meat for a day’s worth of calories (3,300 cal). Killing 25 squirrels with the above ammunition would require 35 ounces of shotgun shells. Using our caloric value for instant mashed potatoes from above at 104 calories per ounce, the same 35 ounces if brought in the form of mashed potatoes instead of shotgun shells would give us 3,640 calories, more than what you would get from the squirrel meat. That means that if you are hunting squirrel with shotgun shells, you will never procure enough meat to offset the weight of the gear that you have to bring. You will be better off bringing food with you rather than the equivalent weight of ammunition. That is not to mention the weight of the shotgun itself, for which you could have brought an additional 3 days worth of food.

The numbers of course look much better when we consider larger game. If we are hunting rabbit, 4 of them would give us the caloric requirement for a day. That would mean we would have the expand 4 shotgun shells, at a total weight of 5.6 ounces. The equivalent weight of mashed potatoes will only give us 582 calories. In that instance, again, assuming perfect accuracy and availability of sufficient targets, the shotgun will be the better bet. The numbers of course look even better when hunting large game like deer.

A possible way to address the problem with small game hunting is to use different ammunition. While a shotgun shell weighs 1.4 oz, a .22LR cartridge weighs 0.1 oz. 25 squirrels will require only 2.5 ounces worth of .22LR cartridges, making it a viable option. The solution proposed by Dave Canterbury is to carry an adaptor, which inserts in the shotgun, allowing you to fire .22LR bullets. While the approach is viable in theory, if that is the route you chose to take, keep in mind that this is quite possible the least accurate way to fire a .22LR bullet. A non properly bedded, 10 inch rifled insert will give only marginal accuracy, made even more difficult by aiming only with the aid of a bead sight. You should adjust your ammunition count accordingly. After all, the goal here is to kill game, not to just fire ammunition.
