Lighting a fire with birch bark is something that I do regularly, generally in combination with a fire steel. More often than not I’ll peel bark from a live tree, occassionally I’ll cut a strip from a dead one. In this video I discuss these two approaches in more detail.
We teach using birch bark to light a fire on our 2 Day & 5 Day Bushcraft Courses as well as the IOL Bushcraft Competency Course. You can see plenty of photos from all of these courses on our Facebook page.
