Throwing axe or knives to the living tree

Some people like to exercise their skills of throwing axe or knives - of course it is interesting and useful skill - but is it OK to do that with living trees, living organisms?

Not exactly.

For tree it is quite same situation as for human whose skin is cut by knife.
Such wounds are dangerous for the tree - as it is open wound it gives a freeway for different microscopical organisms.

It is common view that tree wounds heal - but it is not exactly so - the wounds will not heal - they will covered by the growing cambium cells. That means, even if we can see that tree bark looking healthy - it might not be healthy under the bark.
In Estonia the cambium cells grow and cover the wound usually (depends species and conditions) with speed around 2-5mm per year.
So - if we make some 1cm wound to the tree bark, then it takes least 1 year to cover that wound by the cells.

It is so easy to make some damage to the environment - so - please, keep the nature!
