This is a priority breakdown of how one should set out to start a survival situation with almost no gear and their knife!
First Day- Build a shelter the first morning and get the shelter to a comfortable level of warmth for your climate. It must be dry, warm, and provide a place to store things. Custom debris hut is usually first choice in most climates in our area. I will make sure that my shelter is located reasonably close to a water supply. While I am gathering shelter materials I should also use the opportunity to gather firewood for the fire at night as well. Next, I will begin making a fire with primitive bow drill or a hand drill with thumbhole strings to reduce energy consumption and make getting a coal easier. If I have suitable cordage then I will always go with bow drill first but if cordage is in very short supply then I do the hand drill. At the end of day one I will shift my focus to making several no carve pauite deadfalls and split stick figure four deadfalls. Set them out next to pack rat dens and near other high traffic areas for small game. Before I return to camp I should try to gather natural cordage material to bring back and when night time arrives I can make several feet of cordage around the light of the campfire. Note: Always make time to forage for edibles to and from different spots and make a throwing stick while out in case possible game opportunity presents itself!
Day Two- Begin the morning by re-stoking the fire and go check my nearby traps to see if the overnight traps caught me breakfast. Return to camp and begin either processing trapped game or begin improving your shelter while it is still cool. Shelter building is one of the more labor intensive parts of survival and should be done when the least amount of calories will be used. Then begin making more simple traps as well as a few more complex trap triggers for larger game. If there is fish nearby then immediately begin making fish traps because they are the easiest prey to catch. Bugs, worms, and anything smelly works for land and water traps. While you are out always be foraging for convenient wild edibles and collect any potential harvest the forest provides you with! The second day should almost be completely consumed by shelter improvement and food gathering. But don’t forget to stay hydrated!
Day Three- By day three you should have several dozen traps set out and producing food. This is your main focus until you have created enough food generation sources to provide you with enough fresh meat to eat on hand and enough extra to begin storing extra dryed meats, edibles, etc. Begin putting these things back for your next move. Every time you are out always make sure you are gathering materials when they become available. Don’t wait and come back later only to waste more calories. If you plan to leave your shelter and be on the move, then make sure you have stockpiled plenty of dried food goods for your journey plus a little more than you think you need just in case!
Day Four- When day four rolls around you should be more accommodated to your situation and should be at least providing yourself with a minimal amount of calories to survive without losing to much weight, if any! You should continue to improve on your situation adding new food generation sources and utilizing your areas resources to be prepared for whatever your endeavor may be. You should also have begun making things like drying racks and tools to use to make your work easier!
-In my experience, this generally turns out to be the general timeline of how long it takes to begin being truly self sustained in a known wilderness area. Everyday, is a snow ball effect of how your resources collect and you should take every free minute to improve upon your situation. At night time you should be making cordage and use any free time in a redundant manner to make the most efficient use of your time! When your basic needs are taken care of, then you move on to the higher primitive arts, such as tool construction. Stick with these timeline goals in mind and you will do good in almost any situation!
Summary: Day one make shelter near water, make fire, and then make traps to gather food overnight while you are sleeping; Day two should be shelter improvement, foraging, and making as many traps as you can, especially fish traps; Day 3 Continue making traps, improving shelter, making cordage and start putting food back if you have any excess; Day 4 You should be self sustaining in most climates by this time and should be producing enough food so that you are not losing any weight. Don’t Forget to Stay Hydrated!
