IB Geography - Ecosystems. Biomes - Taiga aka Coniferous forest

• 1.
  Biome presentation Coniferousforest – Taiga
• 2.
  Location Located in: North America Scandinavia Russia Across Asia: Siberia and Mongolia Northern China Northern Japan
• 3.
  Climate in TaigaSub arctic & cold continental climate Cold winds bring bitterly cold air from the Arctic Circle Tilted Earth – taiga is turned away from the sun in winter
• 4.
  Winter Lasts for6 months Cold & severe Temperature –30 °C Some snowfall Lasts for 3 months Hot & humid Temperature 30 °C A lot of rain Summer
• 5.
  Temperature Highest temperaturesin July & August (30 °C) Lowest in January & February (–30 °C) Most rainfall from June to August Most snow from December-February Precipitation
• 6.
  Vegetation NPP –800g/m2/yr Nutrient cycle: Litter – the largest Biomass – medium Soil – the smallest Nutrient cycle
• 7.
  Vegetation Very fewspecies Needle leaf trees are dominant & adapted to the cold Coniferous trees can keep they’re needles for 15 years Advantages Needle leaf – have thick waxy coatings Conical shape – prevents loss of branches Evergreen habit – plants can photosynthesize throughout the year Dark green color – helps to begin the photosynthesis early

  Vegetation Mosses Lichen

  4 main needleleaf trees in Taiga Fir Spruce
• 10.
  4 main needleleaf trees in Taiga Pine Larch
• 11.
  4 main leaftrees in Taiga Aspen Birch
• 12.
  4 main leaftrees in Taiga Willow Rowan
• 13.
  Soil Type ofsoil – podzolic Very acidic & sandy Poor in nutrients Poor agricultural soil Leached minerals –restricts the drainage of water through the soil
• 14.
  Animals in TaigaNeed to have special adaptations to survive Adapted to the climate by hibernation Breed and raise the young in the summer Constantly changing population – local animals have to change what they are hunting Food Chain
• 15.
  Animals in TaigaThe bear – omnivore. Eats berries and salmon in the summer Needs to "fatten up" for winter hibernation. Winter – the bear goes to its cave & sleeps until the spring
• 16.
  Animals in TaigaLynx – carnivore Eats rabbits, birds, and other small prey. Adapts by changing its coat to disguise itself. Soft white in the winter Light brown with dark spots in the summer
• 17.
  Animals in TaigaSnowshoe Rabbit – herbivore Eats available plants Has large back feet – snowshoes. Grayish brown fur in the summer Pure white in the winter Can run up to 40km/h and jump 90cm in one hop. An expert at escaping predators like the wolf or lynx. Good swimmers – will swim to make an escape.
