Winter survival food................

This is the time of year when the survivalist can show just what they really know .
winter survival is some ways easier but harder in others , like when setting snares game trails are easy to see in the snow , water is easy to get from melting snow and ice ,
but food , shelter and fire become the main stays since we covered fire in a other discussion and with fire making coming up on the 21st of Oct , I will leave that until then .
Food I will start to cover now so lets start with trees , there are very few places on the planet you can go that are treeless and I will cover them at a later date so lets begin with the
trees that have the best inner bark .
The cambium ( the thin inner bark ) of certain trees are both edible and nutritious and are best in spring when the sap starts to flow but edible any time of year .
Choose bark near the bottom of the tree or from the roots if they are exposed , cut outer bark to get at the inner layer of cambium and peel back with a knife , this in most cases will be mildly sweet and can be eaten raw , but better boiled down to a jelly like state , or if you don't care for jelly roasted and ground to make flour . the list below are trees that suit this propose best.
1) Maples - recognized by their winged fruits and leaves.
2) Pines - evergreen trees their inner bark is rich in vitamin C.
3) Willows - there are many different types including arctic ground hugging ones.
4) Spruces - as well as being a food source the needles make a good tea rich in vitamin C.
5) Poplars - grow well in northern areas as well as their buds can be used as a pain killer .
6) Birches - the white birch bark can be used as fire starter and to boil water in.
these are the best and most often found trees there are many others like elm , basswood and tamaracks that can be found all over .
take the time to learn and identify these trees they could save your life.
