Why designate no-dig zones around trees in construction projects?

• A. To avoid disturbing roots and soil structure
• B. To improve drainage around the site
• C. To speed up construction
• D. To encourage deeper root growth

Answer: (A)

Protecting the tree’s root system and soil structure during nearby construction. Trees depend on a network of roots near the surface for water, nutrients, and stability. If trenching, digging, or heavy equipment disturb or sever those roots or compact the soil, the tree can lose its ability to take up water and nutrients, its roots can be damaged or girdled, and its anchorage can weaken. Keeping a no-dig zone around the tree preserves those critical roots and maintains soil porosity and drainage, helping the tree remain healthy and stable once construction proceeds. This is the fundamental reason for establishing such zones. It isn’t about drainage changes, speeding up work, or encouraging deeper roots; those are not the purpose of protecting the current root system and soil structure.
