Fangorn forest is the realm of Treebeard (also called Fangorn), a tree-giant or Ent (from the Old English for giant), one of the oldest living things, or actually the oldest living thing, in Middle-earth. The Ents are tree-herds; they look much like trees, though they have branch-like arms, root-like legs, faces, and the ability to move and speak. Among their charges are the Huorns, which are either trees in the process of becoming animated, or Ents that are reverting to becoming treelike.
