Follow up on #6 Oak tree

Once the oak was brought to the ground yesterday, it is surprising that the tree lived as long as it did.  It was completely hollow at the base.  The contractor said there were concrete repairs made to the tree up off the ground.  Concrete was used years ago to fill hollows in an effort to stop decay.  The concrete also prevented animals from climbing up in the tree and creating more damage inside the trunk.  Speaking with Tim Gamma a few days ago at one of our functions, he stated that this type of repair seems somewhat strange to many but in a number of cases over the years, he has seen that trees have actually healed themselves and had grown completely around the concrete filling.  Old conventional methods should not always be thrown out because they are not modern or new.  

One could easily crawl inside the cavity of this tree.
