Some specific kinds of tree are important in Tolkien's stories, such as the tall Mallorn trees at the heart of Lothlórien. In Tom Bombadil's Old Forest, Old Man Willow is a malign and fallen tree-spirit of great age, controlling much of the forest. Early in the creation, the Two Trees of Valinor, one silver, one gold, gave light to the paradisiacal realm of Valinor.
