Vegetation Zones

vegetation: lichens, mosses, dwarf shrubs

precipitation: 4 to 20 inches per year

temperatures: cool summers (37-54°F) and very cold winters (-30°F), above freezing (32°F only 2 months each year)

• tundra/polar

• temperate rainforest

• tropical rainforest

• desert

vegetation: trees 300 feet tall, bushes, small trees, and other plants, ground is covered

precipitation: 100-167 inches per year

temperatures: moderate even in the north, seldom falling below 32 F° in winter

• tundra/polar

• temperate rainforest (North America)

• tropical rainforest

• desert

vegetation: Vines, palm trees, orchids, ferns in moss and lichen, one acre might have 6,000 pounds of these tiny plants

precipitation: 80 to 400 inches per year

temperatures: average temperature 70-85°F

• tundra/polar

• temperate rainforest

• tropical rainforest

• desert

vegetation: hardiest bushes, shrubs, a few small trees, and cacti survive there

precipitation: less than 10 inches of rain a year

temperatures: harsh sun, high temperatures, average daytime temperature is 100°F, while at night the average temperature is 25°F.

• tundra/polar

• temperate rainforest

• tropical rainforest

• desert

vegetation: grasses dominate temperate grasslands, trees and large shrubs are rarely found in grassland areas

precipitation: the prairie in the Mississippi Valley may get 30 inches or more of precipitation each year, farther west, the land gets less rainfall-as little as 15 inches in Alberta, Canada-and the grass is shorter

temperatures: dependent on latitude, yearly range can be between -4°F to 86°F
