north the desert begins a temperate climate, cacti gradually give way to shrubs wormwood, quinoa and Eurotia.Wildlife America is unique in its splendor.The territory of the United States by the Appalachian mountain range in the east and the Cordillera rocky in the west, is a series of flowering valleys and barren plateaus, rich pastures in the prairies and endless rocky plains.The whole nature of America is built on contrasts.Therefore, the most fertile and picturesque ranges set aside for national parks.The main reserve USA, Yellowstone Park, spread over a vast area of almost a million hectares.
