Here
we define the Sierra Nevada Foothills as more or less coinciding with the Ponderosa
Pine-dominated forests on the western slope of the Sierra Nevada Mountains. Elevations of
this zone vary, depending on the latitude:
- NORTH: 1200-5500 feet
- CENTRAL: 2000-6500 feet
- SOUTH: 2500-9000 feet
Note that Jim studied mostly between 2600-4500 feet
in elevation, so species appearing only above and below that were not encountered. For
example, just below Jim's elevation Blue Oak was abundant, but Jim never saw a single Blue
Oak tree during his hikes. |
