When a tree bark gets wounded, it is a good idea to prune and tend the wound.
Here is a screen shot explaining why.
A lot of times heavy equipement like bobcats and excavators can bang into trees.
The wounds should be properly treated.
If they are, many times they can seal off and compartmentalize the damage.
An I.S.A. Certified Arborist can be helpful to assess the damage.
Be really careful! A lot of times tree salesmen will try to blow a small wound out of proportion in order to get a sale. (Commisioned based salesmen vs tree health care pose a clear conflict of interest).
