Environment Pollution: Coniferous Pine trees are most at risk from air and soil pollution because of factories and human interference. Trees that are polluted are broken down into four different categories – each category representing how severe a tree is polluted.

Human Activities: NW Coniferous Forests are slowly shrinking because of deforestation. We like to chop down coniferous trees and use them as wood for construction. Increase in population also has potential to harm the forest because when a population increases, so does the demand for more land.

Protected areas: Yellowstone National Park, Mesa Verde National Park, Boise National Park, Yosemite National Park are some of the more well known national parks, but there are hundreds of protected Coniferous Forests located around the world. 4/21/11

Drinking water: Rivers are the main source of drinking water in Coniferous Forests as rivers are extremely common in Coniferous Forests. Another source of drinking water is runoff from mountains when snow melts in the spring.

Environment cont. Natural Disasters: Thunderstorms which lead to Forest Fires, Avalanches, and in rare cases, Volcanoes.


Low Water Quality: If water quality is in bad shape, usually from domestic waste, then the environment will be in great danger of diseases and illnesses. If waste is put into rivers, it effects drinking water and then river will usually empty into a lake, which then effects that entire lake’s ecosystem.

Environment cont. Biotic Factors [Plant Life]: •


Coniferous Trees [Needle Trees]

Redwoods Abiotic Factors: •Water •Weather •Sun •Precipitation


Biotic Factors [Animal Life]: • Racoons • Lynx • Cougars • Black Bears

Geology Faultlines: •

The Portland Hills fault zones and the Gales Creek fault. Earthquakes are common in the region, but they are mostly scattered. Mountains:

Mt Rainier • 14,410 feet above sea level • Located in Washington State • An active volcano • In the Cascade Mountain Range


Major Biome Experiences: •Has major thunderstorms during the summer regularly •Droughts do happen when the humidity is low however.

Climate Climate: •

Fluctuates little throughout the year. Moist climate and long growing seasons. Southern portions of the biome have drier seasons with less precipitation. Mountains effect solar radiation, composition, and amount of available moisture in the biome. Has all four seasons. Latitude and Longitude: Between 23.5 degrees North and 60 degrees North Latitude. 4/21/11

Temperatures/Precipitation: • Lacks temperature extremes (it is never very cold or very hot.) • Precipitation can vary from 50200 inches per year, with the prior amount being in southern locations. • Precipitation is greater during the summer. • Moist climate and long growing seasons. • Weather depends on how close or far they are from the ocean or mountains.
