The Two Towers by J.R.R Tolkien (Harper Collins 1991, 2007) pp. 607-611
Ents are shepherds of trees, tree-herds as Treebeard puts it, and it is in the nature of shepherds to live so closely to the creatures they care for that they can anticipate any action that those creatures might perform. Of course, sometimes a sheep, or perhaps a tree, might do something that takes the shepherd by surprise and if that happens then they will do all that they can to put things right. As that ancient source of wisdom, the Bible, puts it, “the shepherd lays down his life for the sheep”. This does not just mean that the shepherd will die for the sheep although they are always prepared to do so if required but that they give their lives for their welfare from day to day and Treebeard has been doing this for a very long time indeed.

His long life of service to the trees began with a prayer of Yavanna, the member of the Valar for whom the care of things that live and grow upon the earth was most dear. She prayed to Eru to provide for the care of trees. Her main concern then was with Dwarves and their axes, which rather puts into context the advice that Aragorn gave to Gimli about being careful how he used his. Indeed the only other recorded occasion apart from these events at the end of the Third Age in which Ents became involved in the affairs of the wider world was when the Dwarves of Nogrod went to war with the Elves of Doriath and sacked their stronghold of Menegroth.
Menegroth lay at the heart of Doriath, a forest kingdom ruled over for long years by Thingol and by his wife, Melian the Maiar. It was Melian who through her magic arts made Doriath a secret place and it was in that land that Luthien was born and nurtured and where Galadriel learned much from Melian so that the land of Lothlórien in many ways resembled Doriath. It was through the tragic greed of Thingol that led to his death and war with the Dwarves of Nogrod and led to so much destruction of that which had been so beautiful. The Ents fought alongside the Elves in this war and it is quite possible that Treebeard was one of those who fought. His motto of “Do not be hasty” may have been made in those unhappy days and he has kept it. He has not gone to war for thousands of years until the arrival of two young hobbits who come among the Ents as they seek to escape from orcs.

Like trees themselves Ents are patient creatures. Treebeard is able to look back to a time when “there was all one wood… from here to the Mountains of Lune, and this was just the East End.” He ponders the sense of spaciousness that he enjoyed in former days. “Broad days,” he calls them when there was room and time just for breathing. “The woods were like the woods of Lothlórien, only thicker, stronger, younger. And the smell of the air! I used to spend a week just breathing.”
Although he regards the decline of the forests of Middle-earth with sadness we do not get the sense that he does so with resentment or bitterness. As Gandalf will say to him later on he has not plotted to cover the lands with his trees. But at the last he will become angry at the wanton destruction of trees by Saruman who does so simply for the sake of his own self-aggrandizement. His choice not to act hastily has guided him for many long years. He has not been passive in the face of evil but has devoted himself to the care of his Forest of Dark Night, his tauremornalómë, protecting unwary travellers from the worst of that dark and teaching those parts of the forest that have embraced darkness in hatred of the light to rest in darkness as a part of the natural rhythm of things, a time in which the forest can breathe in before exhaling once more in glad welcome of every dawn.
