Tundra siberia

Climate in Siberia

  • Average Rainfall: 6-10 inches per year
  • Average Temperature: -30 degrees F to 63 degrees F
  • Generally only two seasons, summer and winter, summer lasts only a brief few months and is often characterized by large amounts of rainfall and warm temperatures whereas winter is characterized by snowstorms and negative temperatures.

Net Primary Productivity

  • Polar Tundra productivity averages at about 600 kilocalories per square meter per year and about 2 kilocalories per square meter a day.
  • This is far less than all other biomes expect for the dessert which it is only slightly above in kilocalories per square meter per year and day.
  • Polar Tundra is commonly found above 65 degrees north latitude.

Soil Quality

  • Soil quality within the Polar Tundra is very low, lacking any substantial nutrients that would allow for larger plants.
  • Poor soil quality means that only small plants can survive and that it is not suitable for farming.

Invasive and Endangered

Invasive Hill Mustard

  • Originally introduced as a migratory species by the Siberian people, it has now become a commonly spotted weed during the summer months.
  • Become a pest to open areas of the tundra and took over in place of other plants.

Endangered Siberian Tiger

  • Due to their thick and vibrant fur, the tigers have been hunted to near extinction. There are currently around 500 tigers left in the wild. (over harvesting)
  • Having such a small population makes the risk of decreasing genetic resistance higher.

Animals of Siberian Tundra

Musk Deer

  • Thick and multi-layered fur to conserve heat through the winter months.
  • Their hooves are designed for climbing on rough terrain and rocky surfaces.

Eurasian Lynx

  • The coat of a Lynx changes colors over the seasons to help them camouflage.
  • Soft paws aid them in stalking their prey.

Caribou

  • Caribou coats change color with the seasons to help them blend in with their surroundings.
  • They have large cloven hooves that help them walk on snowy and rocky terrain.

Plants of Siberian Tundra

Arctic Moss

  • Able to soak up water and retain it for long periods of time even through winter months.
  • Lack of definite root structure means that they do not need a high quality of soil to thrive.

Pasque Flower

  • Flower is highly toxic to ward off predators.
  • Seed heads make sure that the flower will continue on through the winters and bloom in the summers.

Arctic Willow

  • Grows extremely slowly, allowing for a longer growth and time to reproduce.
  • Round leaves soak up sun when it is available.
