Agarwood trees tend to produce fragrance more easily near the roots.

This is because animals, such as wild boars, may dig into the tree bark with their claws while foraging, causing the tree to secrete unique resinous oil in its fibers.

 

In the wild forest environment, tree trunk injuries can be caused by damage from wild animals or lightning strikes.

 

If artificially inducing agarwood production, any part of the tree trunk can be stimulated to produce agarwood.
