Construction and landscaping projects can be extensive, which can be a problem for trees close by. Though these outdoor projects might not require tree removal, plants near the worksite are still vulnerable and can sustain injuries. Knowing how to preserve trees during construction will provide the protection these plants need.

Professional arborist consultations from Southern Tree Pros can help. We’re a top provider of tree services in Marietta, GA. Explore arborist tips on tree preservation below before starting your next construction job.

Common Tree Injuries Around Construction Sites

Tree injuries around construction zones can take many forms, including the following.

Tree Root, Trunk, and Branch Damage

A tree’s drip line refers to the space between its trunk and the furthest end of its canopy. Drip line preservation is crucial for protecting tree root systems, branches, and trucks, which can sustain accidental damage from:

  • Excavation
  • Soil tilling
  • Trenching
  • Large equipment

Though tree roots can extend far beyond the drip line, the risk of root damage increases the closer you work to the tree. So, it’s best to work far away from it, if possible.

Soil Compaction

Soil compaction prevention is crucial around construction zones with lots of heavy-duty equipment, supplies, and machinery. Their weight easily compresses soil particles, making it harder for the soil around tree roots to retain oxygen and absorb water. A lack of water and oxygen can stunt tree growth for years.

Soil Level Changes

Even if you take steps to avoid soil compaction, other disturbances to the earth around trees can be problematic. These plants get most of their nutrients and moisture from the top 12 inches of soil. Covering that soil with debris, excavated dirt, and other particles can lead to root death.

Tips on Saving Trees During Construction Projects

Arborists learn how to preserve trees during construction as part of their training and education. Consulting with a local arborist is the best way to preserve trees around your worksite. 

The first step in tree preservation is conducting a thorough assessment. An arborist will evaluate the trees, preferably before the construction or landscaping work begins, to determine if the plants need removal or preservation. The best candidates for tree preservation are healthy plants with vigorous growth and no major structural problems. 

Unfortunately, some tree species aren’t ideal for saving around construction zones due to their sensitivity to root disturbances. These include sugar maples, hemlock, oak, and white pine trees.

Consider these guidelines to help maintain the health and aesthetic appeal of trees around your construction zone that will remain once your project concludes:

  • Erect clearly identifiable tree barriers around plants you intend to save beyond their drip lines. The barriers can consist of protective fencing, signs, or mulch. 
  • Utilize protective mulching around the trees’ root system to conserve moisture in the soil and establish a root protection zone. 
  • Avoid washing equipment or dumping chemicals around the root zone.
  • Try to limit heavy machinery and equipment to a single route to minimize soil compaction.
  • Watch tree canopies for signs of dieback, which can occur due to root damage.
