HAVE ENOUGH PRECIPITATION TO SUPPORT
STRANDS OF TREES, FOUND IN TROPICAL
TEMPERATE AND POLAR REGIONS.
Temperate Deciduous Forests
 Most of the trees in these forests survive winter by
dropping their leaves, which decay and produce
nutrient rich soil.
 Found in Eastern United States and Western Europe
Climate
 Moderate Average Temperatures
 Change significantly with the seasons
 Abundant Precipitation
 Often spread fairly evenly throughout the year.
Vegetation
 Broadleaf Deciduous trees- Oak, Hickory, Maple,
poplar, beech


Drop leaves to survive winter and become dormant.
Grow new leaves each spring.
 Rich Diversity of Ground Level Plant Life
 Why? Sun light is able to penetrate leaves.
 Leaf litter is a storehouse of nutrients.

Current Dominant
Mammals
Past Dominant Mammals
 White Tailed Deer, squirrels,
 Bears, wolves, foxes,
rabbits, opossums, raccoons,
mice
wildcats, mountain lions
Animals Cont’d
 Birds
 Warblers, robins, geese migrate to these forests in summer to
feed and breed
Evergreen Coniferous Forests
aka Boreal or Taigas
 Most of the trees in these forests are coniferous
evergreen trees.
 Found South of Artic Tundra in Northern America,
Asia, and Europe
Climate
 Subarctic Climate


Long, extremely cold, dry winters
Short, Cool to warm summers
 Sometimes found in moderate climates
 Ex. Southern Pine Forests in the US
 Precipitation
 SNOW!
Vegetation
 Coniferous Evergreen trees-Spruce, Fir, Cedar,
hemlock & pine


Needle shaped, waxy coated leaves withstand intense cold and
drought
No need to grow new needles during short summers
 Low Diversity of Ground Level Plant Life
 Few species survive winter when soil moisture is frozen.
 Leaf litter decomposition is slow- low temps, waxy needles,
high soil acidity
 Nutrient-Poor Soil 
Wildlife
Year Round Residents
Past Dominant Mammals
 Bears, Wolves, Lynx, moose,
 Warblers, & insect eating
and burrowing species
birds
Acidic Bogs are formed during the brief
summer when soil becomes waterlogged.
