Title: Taiga or Boreal Forest


1
Taiga or Boreal Forest
  • By Ciara Resler, Jordan Stacy, Rebecca
    Silverstein and Troy Gleeson

2
A Needleleaf Forest
  • Climate temperature is below freezing for six
    months out of the year
  • Summer 20 to 70 F
  • Mostly warm, rainy and humid
  • Winter -54 to -1 F
  • Extremely cold, plenty of snow
  • Total precipitation of the year 30-85 cm.

3
Climate
  • Supports harsh living standards in most areas
  • Some animals can't survive in such cold living
    conditions
  •             Ex. animals with fur
  • Trees and other vegetation have to survive
    harsh, frigid winds and lack of lack of heat
  •             Ex. Evergreens

4
Biome Location
  • Located in North America
  • and Eurasia
  • Elevation 1800 ft.

5
Elevations and Major Landforms
  • Mountains
  • -hills
  • -ponds
  • -plains

6
Environmental Concerns
  • Many components are hurting the Taiga.
    Fortunately, there are ways to fix them.

Climate Change
9
White Spruce
  • Needles length 2.5 centimeters
  • Color Evergreen
  • Height (average 150 ft.)
  • Needles hold moisture
  • Hold needles for over 15 years
  • Able to survive in moist areas

10
Paper Birch
  • Thin bark
  • Peels horizontal
  • Grows in clusters
  • Average height 60 to 80 ft.
  • Produce scaly spikes that hold flowers
  • Able to survive from the soil

11
Jack Pine
  • Average height 27 meters
  • Needle Color reddish brown
  • Provide nutrients for animals
  • Turns grey as it gets older
  • Wax pine needles and rough bark allow survival.
  • Seeds located and produced inside their pinecones
    (dark brown)

12
Species
  • Canada
  • 85 types of mammals
  • 130 types of fish
  • 32,000 types of insects
  • Beavers
  • Wolves
  • Grizzly bears
  • Siberia
  • 300 types of birds
  • 30 types of birds stay for winter
  • Ravens
  • Golden Eagles
  • Crossbills

13
Predators
  • Golden Eagles
  • Ultimate predator in the sky, can eat almost
    anything rodents, larger birds, and deer
  • Grizzly Bears
  • Perfect in their environment omnivores, eat
    salmon, caribou, and seeds

14
Predators (continued)
  • Wolves
  • Have an abundance of prey, feast on all types of
    rodents thick furs allow them to survive harsh
    living conditions
  • Ravens
  • can survive the harsh climates and are scavengers

15
Foundation
  • Crossbills beaks have adapted, allowing them to
    get seeds from cones
  • Deer provide a great amount of food to the
    other animals

16
Foundation (continued)
  • Beavers help the prey hide from the predators
    their dams allow deep still water to provide a
    barrier also allows food and building materials
    to float to the surface
  • White-Throated Sparrow have the most difficult
    job in the forest main goal is to keep the
    insect population under control
