Therefore, we can conclude that at least while he was Emperor during the end of the Second Era, Cyrodiil was a jungle. In-universe, the Pocket Guide to the Empire, 1st Edition was written around 2E 864, which is during the reign of Tiber Septim. – Pocket Guide to the Empire, 1st Edition, " Cyrodiil", physical book bundled with The Elder Scrolls Adventures: Redguard There are a few major roads to the west, river paths to the north, and even a canopy tunnel to the Velothi Mountains, but most of Cyrodiil is a river-based society surrounded by jungle. The western coast is a wet-dry area, and from Rihad border to Anvil to the northernmost Valenwood villages forest fires are common in summer. Between its western coast and its central valley there are all manner of deciduous forest and mangroves, becoming sparser towards the ocean. The elevation rises gradually to the west and sharply to the north. As one travels south along these rivers, the more subtropical it becomes, until finally the land gives way to the swamps of Argonia and the placid waters of the Topal Bay. Its center, the grassland of the Nibenay Valley, is enclosed by an equatorial rain forest and broken up by rivers. It is the largest region of the continent, and most is endless jungle.

(Emphasis in this and subsequent quotes are mine). Before Oblivion, Cyrodiil was unambiguously a jungleīefore The Elder Scrolls IV: Oblivion was released, all accounts of Cyrodiil were that it was definitely a jungle.
