Proper-sized barricades around trees can minimize injury. Mechanized equipment can damage tree trunks, root systems and soil structure. Soil compaction and grade changes limit root growth, causing dieback and death. Tree Value, Health and Life Span Shade trees add to the value of residential and commercial properties. During construction, established, healthy trees can be preserved with little effort or expense.
Many trees are valuable enough to justify the extra concern.
Have a city forester, licensed arborist or certified tree appraiser evaluate every tree to see if preservation is worthwhile. Consider location, present size, future size, species, vigor, cost of preservation, and removal cost. Recognize that it is impossible to save every tree. Visualize the future landscape when evaluating trees for preservation. If plans call for preserving existing trees near buildings or in landscapes, the trees should be sufficiently healthy to justify preservation.
