The image to the left shows epicormic regrowth that had developed following the lopping damage sustained by the tree.

Epicormic (Epi - upon) (cormic - stem) (Alex Shigo - A New Tree Biology, pg 43-44) regrowth shown in the image is defined as the development of juvenile shoots from dormant adventitious buds located beneath the bark of a tree. The development of these buds is the trees survival mechanism to the wounding sustained and indicates that the tree is under stress.

The epicormic regrowth in this image is a concern as the shoots that develop are weakly attached to the outer bark and prone to failure as they grow.

Other instances of epicormic regrowth are noted in some species of Eucalypt trees that when exposed to traumatic episodes, such as fire, will develop shoots from latent buds located in epicormic strands that extend from the pith to the outer bark. These are again a survival mechanism of the tree to regenerate the crown. This epicormic regrowth is viewed differently from the shoots detailed in the photo shown, whilst all epicormic regrowth needs to be monitored, the epicormic regrowth extending from lopping damage is more concerning due to the high risk of limb failure and the impact to the health and survival of the tree, sometimes resulting in the premature death or decline in a tree.
