Whether you are remodeling your home or starting completely over, mature trees add value to a property and need special protection during construction. It is not just the trunk that needs to be protected, most damage occurs below ground.
Heavy machinery can be detrimental to a tree's root system and depending on the type of tree, roots can be shallow and extend quite far. Rolling equipment, even if it passes only a few times, can compact soil and roots too densely and be harmful to the health of the tree. Excavating or adding too much soil can also damage roots.
A study done by forestry agents at the Alabama Cooperative Extension and mentioned in the National Garden Association's article 'Protecting Trees During Construction' came up with some low cost solutions:
"Fencing off the critical root zone -- the area around the tree where roots are most vulnerable to damage from soil compaction -- is key. But where constraints exist that make such fencing off impossible, the foresters discovered some simple ways to lessen the impact of heavy machinery. They found, for example, that simply spreading mulch 8 inches deep and covering it with 3/4 inch plywood distributed the weight of the equipment driving over enough to greatly reduce the amount of soil compaction below." Our Pacific Vista Tree Service' staff are experts with all types of trees. We can estimate a tree's root system diameter and depth as well as prepare the area with mulch for protection if fencing is not an option. Let us help keep your trees healthy for upcoming years of enjoyment long after the construction is over!
