| | Biomes in North America (Site not responding. Last check: 2007-10-14) |
 | | North America is comprised of 11 biomes (arctic tundra, desert, broad sclerophyll, pinyon-juniper, temperate grasslands, northern coniferous forest, moist temperate coniferous forest, temperate deciduous forest, mountain complex, subtropical, and tropical). |
 | | To the north of the redwoods in Oregon and southern Washington, where the soil is well drained and precipitation is slightly lower, grow extensive, pure stands of the subclimax species, Douglas-fir (Pseudotsuga menziesii). |
 | | Farther to the north these species are replaced by an association of lodgepole pine, subalpine fir, and Englemann spruce. |
