The official website of The Lord of the Rings Online added a new article about the Baugarch to the Creature section of Codex.
Wandering through the Chetwood and the Blackwold camp is a vile Warg that came with eogan out of the North. Many an unwary woodsman has vanished in the Chetwood, taken by the evil Baugarch. Learn more about this terror in this week's content update!
The details are as below:

Monster: Baugarch
Level: 15
Type: Elite (Melee)
Classification: Beast, Warg, Warg
Type: Elite (Melee)
In the Chetwood, the Blackwold brigands have established an encampment from which they assail the various villages of Bree-land. The entire brigand band put together, however, is not as much of a threat as the guardian left there by eogan of Angmar.
Wandering through the Chetwood and the Blackwold camp is a vile Warg that came with eogan out of the North. Baugarch is feared by all who dwell there, even the wild wolves who make their den to the west of the Blackwold encampment. Many an unwary woodsman has vanished in the Chetwood, taken by the evil Baugarch.
Baugarch was created by the designers of The Lord of the Rings Online: Shadows of Angmar. Players wandering the Chetwood should be wary, for this beast could slay an entire fellowship should they enter unprepared.
