Old Forest
By the time Sauron had been defeated and driven from Eriador, most of its old forests had already been destroyed, leaving remnants such as the Old Forest. (Other vestiges included Woody End in the Shire, Chetwood in Bree-land, and Eryn Vorn in Minhiriath.) The Old Forest was now "hostile to two legged creatures because of the memory of many injuries."
