Transcript of Northwestern Biome

Northwestern Coniferous Forest Abiotic Factors Climate Average Temperatures Average Rainfall The soil that is found in the Northwestern Coniferous Forest
is acidic. You can easily plant and harvest in these locations. Biotic Factors Organisms Animals Plants Location Population, Communities, and Ecosystems food web food chain Symbiotic Relationships Commensalism Parasitic Mutualism Threats Unknown Facts about the Coniferous Forest Bibliography http://www.sciencemadesimple.net/temperature.php The West Coast of The United States, Canada, Asia, and South Europe.
It is just below the Tundra. There are many different places where this forest is found. Such as... http://earthobservatory.nasa.gov/Experiments/Biome/bioconiferous.php Lowest recorded: -40 F
Highest recorded: 68 F
Average recorded during summer: 50 F Lowest: 11.81 Inches
Highest: 35.43 Inches http://scienceray.com/biology/ecology/coniferous-forest/2/ General Climate Swampy and cold
Winters can last up to 7 months
Summers are short and warm There are many different types of organisms that live in the Northwestern Coniferous Forest. For example:
Herbivores: Elk, Deer, Beavers.
Carnivores: Owls, weasels, and bobcats.
Omnivores: Bears,Clark's Nutcracker There are many different types of vegetation in this biome:

Douglas fir trees, Sitka Black and Blue Spruce trees, Western Hemlocks, and Redwoods.
Also in coniferous forests are: poison ivy and oak, Aspen trees, mosses, giant Sequoia trees, Fire Weed, mushrooms, and Larch Trees. Mutualism: Commensalism: Parasitic:
A parasitic relationship is a relationship is where one party is helped and one party is harmed.

Bugs and fungi feed off of the trees inhabited in coniferous forest, and causes the trees great weakness. A mutualism relationship is where both parties are helped.
Fungi and algae help each other in this biome. Small pieces of fungi help algae absorb water and other nutrients for the aglae to eat. While the algae provide the fungi with the products of photsynthesis: which is their food.
Another example of a mutualism relationship is when a Mountain Bluebird eats berries off of a fruit-bearing tree. The tree's seeds are then spread out so that the tree can reproduce. Both parties are helped because the Bluebird gets something to eat and the tree gets to reproduce. The Northwestern Coniferous Forest is also called the "Taiga" or the "Boreal" forest.

Many people get the opportunity to go to a coniferous forest when they visit Redwood National Park in California. This park has tours of different parts of the forests and contain some of the oldest Redwood trees found.

Several of the animals in the forests are endangered:
Grizzly bears and Spotted Owls are considered to be endangered in Canada and threatened in the United States.

The bobcat that lives in the Northwestern Coniferous Forest has evolved over time so that in the winter, it grows a white coat.

The Clark's Nutcracker is one of the few birds to have the males incubate the eggs during reproduction. Many different populations live in the Northwestern Coniferous.
Elk and deer, owls, bears, weasels, eagles, bobcats, etc.
Several different trees: Redwoods, Sitka Spruce, Oak, Douglas Firs, Balsam firs, and Western Wemlock are a few of the types of trees. All of these species live together in a community that spreads over the coast of North America, and some parts of the eastern hemisphere. The ecosystem of the Northwestern Coniferous Forest includes all of the organisms, the acidic soil, metamorphic rocks such as granite, and other materials that were deposited by glaciers and rivers. http://www2.for.nau.edu/courses/for212/foresttypes/boreal.htm A commensalism relationship in a biome is where an organism is helped and the other organism is not affected.

An example of a commensalism relationship in the Northwestern Coniferous Forest is when a Clark's Nutcracker makes a nest in a tree in the forest. The Nutcracker is helped because it keeps its eggs safe while the tree is unaffected. http://www.allaboutbirds.org/guide/Clarks_Nutcracker/lifehistory Threats of the Coniferous Forest: Some threats the Coniferous Biome is facing are fires and deforestation, which causes other problems as well such as soil erosion, loss of different life forms, and a loss of the habitat for the animals. http://www.inchinapinch.com/hab_pgs/terres/coniferous/c_forest.htm
