Transcript Temperate Forest

•In the spring & summer, food is plentiful
•Most animals have babies at this time of year
•In the winter, food is scarce.
•Plants go dormant, insects disappear, & there is no
fruit or flowers.
•Most animals hibernate when winter comes
•Rabbits
•Bobcats
•Mountain lions

Most have 3 levels of plants
1st level (forest floor) :
lichen, moss, ferns,
wildflowers.
2nd level (understory):
shrubs
3rd level (canopy): hardwood
trees like maple, oak, birch,
magnolia, sweet gum, and
beech.
•grow between the tropics and the polar regions in both the
Northern and Southern Hemispheres
•Very fertile soils that are rich in nutrients, & great use for
farming
•Fallen leaves create leaf litter. Leaf litter is one of the most
important parts of the temperate forest. This is where the forest
recycles most of its nutrients. Inside and beneath this leaf litter,
thousands of small animals live, like beetles, millipedes,
centipedes, and ants. Unseen microscopic creatures such as
fungi and bacteria live there, too. All these organisms help break
the leaf litter into nutrients other plants and animals can use.

High levels of
precipitation & humidity.
4 definite seasons: winter,
spring, summer & fall.
Average yearly
temperature : 50 F
Average yearly
precipitation: 30-60
inches
Changes most out of all
the biomes
logging for farming
• housing
• timber
• Climate change can also be a
threat to animals
• In the last 30 years, scientists
have discovered that air
pollution from factories, coalburning power plants, cars,
and other sources mixes with
rain to make acid rain. Over
time, acid rain kills trees and
other plants.
