The main terrestrial ecosystems
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
Tropical Rain ForestFound in very humid equatorial areas such as:IndonesiaAmazon River basin
