SavannaCharacterized by a cover of grasses, isolated trees, small groves of shrubs

Compact soils, frequent fires, and large animal action

Located in large parts of eastern Africa, southern Brazil, and northern Australia

Temperate Deciduous ForestCold winters halt plant growth for several months

Trees shed their leaves in Autumn

Spring new plants grow

Fertile soils rich in humus

Eastern U.S. southeastern Canada, most of Europe, parts of Japan, China, and Australia

Taiga

Largest biome in the world

Winters very cold with snow

Summer warm, rainy, humid

Coniferous trees

a.k.a. boreal forest

Eurasia and North America

Temperate Grasslands

Mix of grasses & fertile soils

Plains, prairies

Periodic fires

Tundra

Characterized by permafrost

Short cool summers, soggy wet ground, winter topsoil freezes

Cold temperatures, high winds, short growing season

Northern North America, Asia, Europe
