The hamadryad is a type of dryad in Greek mythology. Unlike many dryads, hamadryads are born bonded to one particular tree. They are often said to be the tree itself, rather than separate entities.
It is believed that if the tree a hamadryad is bonded to dies, the hamadryad itself will die. As a result, dryads will punish any human who harms a tree.
