Modified from C.Hill10/26/2009

TundraPermafrost, continuously frozen groundLarge mammals with good insulation that include: musk oxen and caribouSmaller animals include: lemmings, arctic fox, and snowy owl.

TundraNorthernmost limits of plant growthHigh altitudesLittle precipitationExtremely cold winter air temperatureAlaska, Canada, Scandinavia, and Russia

Taiga: Coniferous ForestsCone-bearersSpruce, Pine, Fir, and HemlockHarsh winters, short summersThin, acidic soil

Taiga: Coniferous ForestsTaiga, the most extensive, stretchs across North America and Eurasia reaching the southern border of the artic tundra.

Deciduous ForestsSufficient moistureLarge treesOak, Hickory, Beech, and Maple Experience each season

Deciduous Forests

Dominates most of the eastern United StatesSoil rich in inorganic and organic nutrientsSupport speices such as: arthropods, birds, small mammals, bobcats, foxes, black bears, and mountain lions

Mediterranean forestDense, spiny shrubsTough evergreen leavesMild, rainy wintersLong, hot, dry summers

Mediterranean forest Require occasional fires for long-term maintenancePlants regenerate quicklyAnimal browsers such as: deer, fruit-eating birds, seed-eating rodents, lizards, and snakes

DesertsSparse rainfallRapid evaporationNo perennial vegetationScattered shrubs and cacti

DesertsDesert plants and animals adapt to drought and extreme temperaturesOnly active during cooler nightsConserve water and seed-eaters such as: ants, birds, rodents, lizards, snakes and hawks

SavannaDominated by grasses and scattered treesFrequent firesRapid growing grass, good food source

Savannatropics in central South Americacentral and South Africa; home to giraffes, zebras, antelopes, baboons, lions, and cheetahs.

Tropical Rain Forest

Rain is abundantPoor soilLarge treesClosed canopy
