Silver Birch as a food source. During early spring, as the tree awakens from its winter slumber, it starts to draw sap up into its leaf canopy. At this point, the tree can literally be tapped for this sap. To extract the sap, simply pierce the bark with a knife or nail. Within a few seconds, you will see the sap begin to flow from the puncture. This can be harvested into a bowl or bottle. The sap from Silver Birch can be consumed as is and is widely regarded as a health food. It contains sugars (fructose) which provide energy as well as vitamins and minerals, for general well being. Naturally, it is also a great way to rehydrate. Secondary products can also be made from the sap.

In times of hardship, the living layer of bark, underneath the outer bark was harvested, bolied and consumed. Provides energy and roughage. In desperation, this layer of bark can be eaten raw! This was a common practice throughout Europe during the WWII.

NB - Many plants can look and smell like another, please be sure you know what you are picking and eating!
