Tree Inventory and Health Evaluation

A thorough tree inventory assessment involves cataloguing each tree’s species, size, and current health status. Special attention should be given to species like oak, white pine, and sugar maple, known for their sensitivity to root disturbance during construction. Since the majority of tree roots reside in the top 6-24 inches of soil, with the taproot providing stability, our evaluation must be meticulous. Recognizing signs such as dying branch tips, split bark, insect emergence holes, and exposed roots is crucial in diagnosing potential problems early.

Selecting Trees to Preserve and Remove

Once the tree health evaluation is complete, the next step is selecting trees for preservation and those that need to be removed. Given the significant value that mature trees bring to the landscape, every effort should be made to save these specimens. Effective root zone preservation is critical, requiring protection of at least 60-70 percent of the tree’s root area during construction. Measures like installing protective fencing around the root zone, minimizing soil compaction by keeping heavy machinery away, and avoiding material storage over roots are essential. It’s also vital to consider the cost-effectiveness of replacing trees that are beyond saving instead of expending resources to preserve them.

Mature trees offer invaluable environmental benefits such as acting as windbreaks in winter and providing cooling effects in summer. Our planning and expert assessments ensure that we make informed decisions, balancing construction needs with environmental stewardship.

Planning Ahead: Protecting Trees During Construction

Properly planning ahead is essential to safeguard our trees during construction activities. Our approach involves establishing effective tree root protection methods and creating designated tree protection zones to ensure their health and stability.

Tree Root Protection

Tree root protection starts with understanding the critical root radius method, which advises 1.0 to 1.5 feet of protected root zone per inch of a tree’s diameter at breast height (DBH). Consulting an arborist is crucial, as they can identify the Protected Root Zone (PRZ) necessary for each species and recommend appropriate protective measures. On construction sites, maintaining a regular watering schedule and covering the PRZ with wood chips or mulch after good rainfall are excellent practices to uphold tree health.

Establishing Tree Protection Zones

Tree protection zones are integral to minimizing construction impacts on trees. For woodlots under two acres, it is advisable to inventory all trees with a DBH of two inches or more. Larger areas might necessitate a partial or complete inventory to identify which trees can withstand construction stresses. In addition to creating designated protection zones, educating workers regarding their significance helps prevent activities that might disturb these zones and lead to tree mortality.

Installing Tree Protection Barriers

Tree protection barriers, such as temporary tree fencing, play a vital role in safeguarding trees from construction damages. These barriers should be strategically placed to prevent soil compaction and root disturbance. Protecting the top 18 inches of soil is crucial, as around 85% of tree roots reside there, covering two to three times the area of the aboveground parts. Ensuring proper traffic routes and waste disposal also aids in protecting trees during construction. Employing such measures helps maintain an ecological balance, fostering sustainable building practices and preserving our valuable urban greenery.

  1. Conduct tree inventories for areas under two acres or larger partial assessments.
  2. Consult with arborists to determine the PRZ.
  3. Maintain regular tree watering schedules.
  4. Apply mulch after rainfall to PRZ.
  5. Establish clear tree protection zones and educate workers.
  6. Install temporary tree fencing and barriers.
