Tarmac Around Oak Trees Causes Root Suffocation and Bark Loss

Paving Kills Roots Slowly

If the council laid tarmac over the root zone, water and air can no longer reach the roots. Soil compaction pushes out oxygen, and the tree slowly starves.

Symptom Progression

Foliage browns and drops prematurely.
Bark begins to slough off as the vascular system fails.

Protecting the root zone from paving is essential for long-term oak survival.
