(Capcom's primary storyline)
The Raccoon Forest (ラクーンフォレスト) is an expansive forest that lies north of the ruins of Raccoon City. It is considered to be an old-growth forest, that is a forest that has attained great age and biodiversity without significant human interference. The Arklay Mountains are located within the forest, on its western side.
The forest has had fairly limited human influence outside of the establishment of Raccoon City downhill. The only known settlement within the forest is Stone Ville. A hospital was also located deep into the forest, and may have been close to this community.
The forest was considered to be a treasure trove for its complex local ecosystem. Its abundance allowed for significant evolution of the RNA-based t-Virus in the event of a viral outbreak, a fact which then-Umbrella virologist Albert Wesker understood well.
