Temperate Deciduous Forest
Europe, East Chinee, Eastern North America Stable precipitation, variable seasonal temperatures Common trees: oaks, beeches, and maples Think of forests around dad’s house
Temperate Grasslands(steppe or prairie)
more extreme temperature variation between seasons;minor precipitation;once widespread across parts of North and South America; have been converted to farmlands;Bison, prairie dogs, etc;Think of nomadic;Native Americans
Temperate Rainforest
Coastal Pacific Northwest;High precipitation; moist, mossy interiors;Coniferous (fire-adapted) trees: cedar, spruce, hemlock, fir;moisture-loving animals;fertile soil susceptible to erosions; landslides;Think of the woods in Twlight; in Washington
Tropical Rainforest
Central and South America, southeast Asia, west Africa;year-round rain and warm temp;lush vegetation, but poor, acidic soils; nutrients in plants;high biodiversity, but at low densities;easy; Brazilian rain forest; many endangered animals b/c of low densities
Tropical Dry Forest
India, Africa, South America, northern Australia;wet/dry seasons;warm, but less rainfall;converted to agriculture;erosion-prone soil;think of ELG trained monkey video; tigers
tropical grassland interspersed with treesAfrica, South America, Australia, IndiaMinor temp cahnges, but high precipitation in rainy season onlyZebras, gazelles, giraffes, lions, hyenasThink of Africa!
Dry; very low precipitation;Some deserts are bare sand dunes; others have more vegetation;not always hot; temps vary widely; nights cool;soils often saline;nocturnal or nomadic animals; plants have thick skins or spines;obvious
Canada, Scandinavia, Russia;minimal precipitation; high seasonal variation in temperature (very cold winters);Permafrost;Few animals can survive year-round: polar bears, caribou;Lichens; few trees; litte vegetation;Think of Antarctica, Russia, N.


Boreal Forest(Taiga)
Canada, Alaska, Russia, Scandinavia;variation in temp and precipitation;cool, dry climate: long cold winters and short cool summers;poor, acidic soils;a few evergreen species dominate;Think of Alaska ; Canada
Limited to small patches: Mediterranean Sea, California, Chile, S. Australia;High seasonal: mild wet winters, warm dry summers;frequent fires;fire-adapted, densely thicketed evergreen shrubs;Think of Cali
