Coniferous Forests
By: Natalie HendersonSlide2
What is A Coniferous Forest?
A forest made primarily of conifers, or trees producing needles and or cones
Example: pine tree, spruce tree, fir tree
Forests that have 4 distinct seasons
Northern Coniferous forests also called:
Taiga Forests
Boreal Forests
Cold forestsSlide3
Climate
Typical Coniferous forests have long, cold winters and short warm summers
Winter: 6-8 hours of sunshine
Summer: up to 19 hours of sunshine
Precipitation: 20-200cm (a lot in snow form)
Average Temperature: ≈-40°C - 20°C Slide4
ClimatogramsSlide5
Where are coniferous forests found?
Typically found in northern hemispheres (North America, Northern Europe, and Asia)
Usually just below arctic tundra
subarctic climate
Ex: Coniferous forest found in Rocky Mountains Slide6
Animals and Plants
Conifers, mosses, and lichens (plants)
Bobcats, lynx, Siberian tigers, bears, wolves, owls
Elk, moose, porcupines, snowshoe hares, other small animals
In summer: birds, flies, mosquitoes and caterpillars Slide7

Plant Adaptations
Coniferous trees – needles and cones covered in wax to resist cold temperature and retain more water
Cones contain seeds – usually at least two
when birds find the seeds they usually only get one seed
Another seed is left to grow
Mosses and lichen grow on forest floor because they can grow with little sunlight
Blocked by tall coniferous trees Slide9
Animal Adaptations
Some animals hibernate through cold winter
Some animals hide and live under the snow
Birds migrate south for winter
Snowshoe hare – white fur blends in with the snow and is well protected Slide10
Humans and Coniferous Forests
Humans cause threats to many coniferous forests through:
Global Warming – other trees will be better suited to warmer climate
decrease of conifers
Development of land for oil and natural gas reserves
Disturbs natural habitats
Logging and deforestation Slide11
