The Great Plains bio-geographic region is that high dry strip of land not more than 500 miles wide, lying just east of the Rocky Mountains, running from Canada to Texas. Its altitude of 2000' - 5000' above sea level and its low rainfall of 10" - 20" per year contribute to a climate of harsh extremes in a land of precious little topsoil.

The plants here are different from their lower altitude or higher altitude cousins, but are no less beautiful nor less deserving of study, protection, preservation and appreciation.
