They inhabited and were spiritually tied to trees like oaks, elms, hollies, and rowans, and would die if their trees were cut down. Like the Wood Nymphs, or Dryads, they were capable of leaving their trees and assuming physical bodies, or using their trees as their bodies. One description of a Wood God is given in Prince Caspian, in that the Wood God of an oak tree would look like a wizened old man with warts and hair growing out of the warts.
