Keep in mind that some species of plants are poisonous, thus you shouldnt eat anything you cant identify.
Everything you find in wild you should identify to know its not poisonous, harmful or containing toxic waste.
This is meant as education for survival situations, its not complete and you shouldnt rely on this alone.
If you have some food to add to this list, feel free to do so by commenting below.
1. Algae
Its basically plants that grow under water, in rivers or seas. Some are poisonous while some are edible and even available during winter.
2. Tree catkins
Probably the single most common food in forests. Many trees produce edible catkins, only some produce poisonous ones. Squirrels eat tree catkins when nuts arent available.
3. Willow leaves
Willow leaves are painkillers. They contain elements which reduce pain. They are also edible in small amounts.
4. Dandelion leaves
Dandelion is an invasive plant, but its also edible. It does have a poisonous look alike.
5. Dandelion flowers
6. Dandelion wine
You can make wine from dandelion flowers, although making your own alcohol could introduce more risk of poisoning, since home made alcohol has poor safety record.
7. Dandelion roots
Dandelion roots are only good in spring while they are soft. After that they become too hard to chew.
8. Tree bark
Many animals eat tree bark, but they never eat too much. Small amount of tree bark from safe tree is safe to eat, but never eat too much because tree bark can cause constipation if eaten in too large amounts.
9. Soil
Many animals eat soil, including monkeys. Its not really known if soil is safe, if its beneficial for humans, or what benefits it adds. Still, its worthy of mention so that more research can be made about it.
10. Tree leaves
Some trees have edible leaves.
11. Tree nuts
These are most calorie dense foods in the world. For example, walnuts have about 700 calories in 100 grams. Some nuts need to be cooked before you can eat them.
12. Tree fruit
Fruit is also high value food which adds both taste and calories.
13. Berries
These are, just like fruit, very significant in value, but hard to find.
14. Mushrooms
Mushrooms are one of those things which are both scary and attractive. They are scary because many of these can kill you if you eat them.
They are attractive because if one knows enough to make difference between poisonous and non-poisonous, he gains a very valuable food source.
15. Eggs (from birds nests)
Birds eggs arent going to add much, but they will add some nutrition necessary for survival.
16. Nests containing nuts, animals
Squirrels nests often contain nuts. Nests can also contain small animals if you feel like being a meat eater.
17. Grass seeds
Probably a bad food source. Grass seeds are actually better choice to feed chickens with than for human consumption.
18. Insects
Insects are plenty in nature. Insects such as grasshoppers are very nutritious. The only problem is utter disgust caused by people eating them.
19. Fish
Fishing is a useful skill. While some fish are dangerous or poisonous, many are edible.
For fishing, one just needs rod, silk and hook.
The bait is found easily in nature, since insects can be used as bait.
20. Hunted animals
I am not sure how much hunting skills would help, but these usually require some skills about making weapons or traps.
Now, it helps if you already have a weapon.
21. Hunted birds
Birds are easy to hunt. Some people even manage to hunt them with slingshot.
22. Buds that are small leaves from trees
New, young leaves from trees are easier to chew than formed leaves.
23. Tree sap
Some trees produce sap which happens to be edible, so it adds to available food.
24. Honey
This one is probably the most dangerous food source, since it is usually protected by hundreds of bees capable of killing a person.
Yet it contains significant amount of calories.
Keep in mind that this is just a list. Each of these needs to be further researched to learn whats safe, what species and types are safe, how to prepare... how to process...ect.
No one should use this list as a guide itself, but rather as a point to which potential food sources need to be researched more.
