In 3019, Lindenroot was among the Ents that attended the Entmoot, a gathering or meeting which didn't happen very often during the early ages. There, he and the Ents would discuss and come to the conclusion that the Ents must go to war against Saruman. Later, Lindenroot, along with many Ents, followed Treebeard, Merry, Pippin to Isengard since they were unhappy that Saruman and his forces were burning and cutting down their trees. He fought in the Battle of Isengard and survived.
- Lindenroot was a The Lord of the Rings Trading Card Game character and does not appear in the books.
