This is the only occasion on which I’ve found inner bark of beech. Over the winter a beech branch came down and so I put it to one side to use later for some carving. I went back to it recently and found that I could pull away fibres from the inside of the bark. Normally with beech, it tends to go hard and isn’t particularly useful for fire lighting.
We teach natural tinders such as inner bark of beech on our 2 Day & 5 Day Bushcraft Courses, the IOL Bushcraft Competency Course</.
You can see plenty of photos from all of these courses on our Facebook page.
