For the first criterion, Shennongjia is apparently one of the most “complete” natural areas in the world.The region rises from about 400 metres to over 3,000 metres above sea level, giving it the name the “Roof of Central China”.The vast range in altitude results in a great variation in climatic conditions.This allows a wide variety of species to thrive.
