How does vegetation vary according to the altitude in the mountain forests ?
For each 1,000 foot rise in altitude there is a 4°F drop in temperature. For example, if at sea level the average temperature is 75°F, at 10,000 feet the average temperature would be only 35°F. This has a dramatic effect on plant and animal distribution.
