General Information• Temperature
– Between -65° and 70°F – For half of the year, the average temperature is below freezing.
• Precipitation– The average precipitation per year is about 40 inches. – Forms of precipitation are rain, snow and dew.– Most of the precipitation in the Taiga falls as rain in the summer.
• Solar Insolation– The main seasons in the taiga are winter and summer. – Winter lasts up to six months.– Short summers (50 to 100 frost-free days) are characteristic. – Fall is the shortest season.
• Limiting Factors– The main limiting factors in the Taiga are the extreme cold, heavy snow fall
and food shortage.

Species Diversity• Plants
– Not a lot of species of plants because of the harsh conditions and the extremely cold winters.
– Some lichens and mosses.– Most plants are coniferous trees like pine, white
spruce, hemlock and douglas fir. – The taiga also contains some deciduous trees like
birch, aspen and alder.• Animals
– Animals of the taiga tend to be predators like the lynx, wolverine, bobcat, mink and ermine.
– They hunt herbivores like snowshoe rabbits and red squirrels.
– Red deer, elk, and moose can be found in regions of the taiga where more deciduous trees grow.
– Many insect eating birds come to the taiga to breed.– Seed eaters like finches and sparrows, and
omnivorous birds like crows stay all year long.

Interesting Facts• Adaptations
– Most evergreens have a cascading cone shape. This allows snow to roll off of its branches.
• If the branches held more snow it would increase the chance of them breaking during a heavy storm.
– Needles are adapted to the taiga environment. They lose less water and shed snow more easily than broad leaves
– Some animals have structural adaptations that help them survive in the taiga.
• The Canadian lynx's wide paws work like snowshoes. • Grizzly bears avoid the coldest weather by going into their dens in the
fall and staying there until the early spring.
• Decomposition– Because of cold temperatures decomposition is slow in the taiga. – Since decomposition is slow, the soil is thin and lacking in nutrients. – Trees grow taller where warmer temperatures allow for faster
decomposition or where streams and rivers carry nutrients from higher ground.
