Editing Copper Canyon (section)

==Flora and fauna==
The Sierra Tarahumara Occidental region contains numerous species of pine and oak trees.
[[Mexican Douglas-fir]] (''[[Pseudotsuga lindleyana]]'') trees cover the high plateaus in altitudes over {{convert|8000|ft|m|disp=flip}}, but due to deforestation in the area, many species of wildlife are endangered. [[Cougar]]s live in the remotest of regions and are rarely seen.  After the summer rainy season these upper regions blossom with wildflowers until October.

From {{convert|4000|-|8000|ft|m|disp=flip}}, [[oak]] trees grow in the huge forests as well as the more shade-tolerant types of trees.  In the fall the forests become brilliant with color from Andean alder (''[[Alnus acuminata]]'') and poplar (''[[Populus]]'' spp.) trees.  Brushwood and scrubby trees grow on the canyon slopes, which can accommodate the dry season.  Huge fig (''[[Ficus]]'' spp.) and [[Arecaceae|palm trees]] thrive at the bottom where water is plentiful and the climate is tropical.
