In the north there are arctic tundra (eg Greenland, Yukon), passing through a great variety of forests (Rocky Mountains  Appalachia and the three Mother Sierras (in California and Wyoming)), tropical forests (Lacandon Jungle, Hawaii and the Chimalapas), deserts (Sonoran Desert, Zona del Silencio), plains (Great Plains, Comarca Lagunera), mangroves (eg Luisiana, Tabasco), etc. Grosso modo, the vegetation associated with them is typical of the Holoártico empire, in the north, and of the Neotropical empire, in the south.
