Northwestern Coniferous ForestIncludes area from coastal ranges of
Northern California to the southern part of Alaska
Stretches through Oregon, Washington, and Minnesota and other northwestern states
Northwestern Coniferous ForestDefinition: a type of forest
characterized by cone-bearing, needle-leaved trees
GeographySandy and gravelly soil along river
beds Mountainous, uneven groundsRanges from 2000 to 12,000 feet in
elevationIncludes Rocky MountainsForest is divided into zones at different
elevations including many types of trees, plants, and animals
GeographyForest is divided into zones at
different elevations including many types of trees, plants, and animals
ZonesMountain Complex of Southern Rockies- reaches altitudes of 12,000 feet
Creosote Bush-greasewood Association- hot, dry, lower slopes below 6,000 feet
Pinyon-Juniper Association- between 5,000 to 7,000 feet
Ponderosa Pine Zone- found from 6,000 to 8,000 feet
ZonesDouglas-fir Zone- 7,500 to 9,000 feet
Spruce-fir Zone- between 8,500 and 11,500 feet
Alpine Tundra Zone- occurs above timberline
Subalpine Zone- found around 2,000 feet in elevation
MeteorologyUp to 200 inches of precipitation on
mountain slopes Climate consists of long winters with
heavy snows and short, dry summers with cool temperatures
MeteorologyLower slopes of the eastern cascades
are especially dry, rainfall ranging from 10-40 inches a year and a long dry summer
Cold winters and cool summers are caused by arctic air masses resulting in extreme temperature variations
Most precipitation occurs during warm months
Human InfluenceClear-cut logging is the biggest threat
Clear-cutting accelerates soil erosion, degrades wild-life habitat, and leads to the loss of biodiversity
BotanyConiferous forest cover huge areas but
have fewer kinds of plants and animals than any other forest.
Many coniferous forests are enormous; they are some of the last wild places in the northern hemisphere.
Some of the coniferous forests in Canada are half frozen and the trees only grow for a few weeks a year.
BotanyBoth big leaf maple and red alder are
pioneer tree species on recently burned and heavily logged areas in the region.
Western Larch and Western White Pine are important successional species in this eastern extension.
The Creosote bush-greenwood association occupies the hot, dry lower.
Douglas Fir
• Shining green color
• Wood is very strong.
• Needles do not fall off easy.
• Usually grows between 40-60 feet in height but occasionally this tree can grow up to 250ft high.
• Leaves are between 1- 1 ½ inches in length.
Willow Tree There are about 300 different
types of willows. The longest willow grows over
120 feet high. They are planted in wet
regions so their roots can soak up the water to dry out the soil.
By providing shade, the willow protects the fields.
The twigs are used to make baskets and wicker furniture because they can bend so easily.
The willow bark provides a material that can be used to relive pain and fever.

ZoologyBecause the plants grow so slowly,
animals need to roam over large areas to find enough food.
Snow LeopardSoft, grey coat with white
on the stomach and solid black or brown spots on his head and limbs.
Black streak down its back.
Lots of fur o their paws for protection from the cold and snow.
Head and body length= 47-59 inches and the tail is 31-39 inches long.
Lives mostly in the mountains and rocky places.
Red FoxHunt mostly at night and
remain active the year round. They often roam grassy
meadows and listen for squeaks of mice.
They sometimes stand on their hind legs to get better view in tall grass.
A fox may lie in wait and pounce on a ground squirrel or wood chuck.
Most commonly found in Canada and Northern North America.
