– Between -65° and 70°F
– For half of the year, the average temperature is below
– 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
• 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.
– 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 of the taiga tend to be predators like the lynx,
wolverine, bobcat, mink and ermine.
– They hunt herbivores like snowshoe rabbits and red
– 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.

Bobcat eats squirrel
– 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 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.
– 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
