Cork oaks
I watched the programme on BBC 2 which showed the cork oaks after harvet. How come they
don't die after the bark has been stripped off? If I took the bark off a normal tree all the way round, it would die.

Its amazing that a mature tree can replace the cork in as little as 3 years. DerekW |

If I took the bark off a normal tree all the way round, it would die. It's not the bark that is critical its the layer immediately below it which channels the food up from the roots to the rest of the tree. With most trees, it is impossible to remove the bark without also removing the layer underneath. The cork oak has developed thick bark which will peel off without taking off the layer underneath, not sure why. Defence against something, presumably, but I don't know what. I seem to recall that cork is a defence against fire. http://books.google.com/books?id=5uiycUoRmFkC&pg=PA112 -- Stewart Robert Hinsley |
