I can see why birch bark was used for a thousand years to make canoes. Our northern forests are full of stovepipes, the durable circles of bark with the wood center long since rotted out. Should one punch a hole in the hull, repair materials were readily available making birch bark a smart choice. 
Didn’t realize how sturdy birch bark was. Sure makes sense, though. M
