When bark is on a tree is it dead or alive?


The outer bark is dead while the inner bark (cambium) is living tissue

Anthony R. Brach, Ph.D.

Outer bark is dead, inner bark, just underneath the woody dead layer is alive and growing; a new layer is added every year from underneath as old layers die.
