Slide1

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
