The best protecion is limiting all activity under trees you want to protect.
TREE PROTECTION is critically important on construction projects where owners want to preserve their trees. The arborists at TBW take advantage of their many years of experience helping to design and implement tree protection plans to minimize the negative aspects of the construction process on established trees. The most important aspect of tree protection is advanced planning. It is far easier to protect against damage than to repair damage after it has been done. If your builder says "oh, don't worry about it, we build around trees all the time and they will be fine", you need to worry. The trees may look fine for a while, but it usually takes several years for the real impact to become noticeable. That is when many people call the arborist.
Effective tree protection is a joint effort supported by owner, builder and arborist. If the builder doesn't sign on to the plan, the chances of success will be slim. Someone must police or enforce the agreed to measures in the plan. If it is not policed, it will not happen.
