Trees and Shrubs
Every plant species has certain environmental requirements for sunlight, temperature, soil conditions, moisture, drainage, exposure, etc. that determine where it can grow successfully. The idea of plant communities – of plants with similar requirements growing together in specific places on the landscape – originated near Walnut Canyon in the late 1880s.

Original proposals in 1915 called for establishment of a Cliffs National Monument at Walnut Canyon. The name was changed to Walnut Canyon National Monument to avoid confusion with a nearby railroad siding, mill town, and post office called Cliffs.
