UNITED STATES BOREAL FOREST
principal characteristics
description
It stretches across the continent from the east side in Labrador to the west side in Alaska. The estimated area covered is 2,000 kilometers. The forest is also known as the snow forest. It is considered one of the most important terrestrial ecosystems.
climate and weather
Boreal forest temperatures below the tundra region are cold. The average temperature is estimated to be between -30°F and -65°F. During the summers the temperatures change drastically and can be moderately high. The temperature can rise to an average of 20°F to 70°F.

There are six seasons, identified by a race of people who live in these forests called the Cree. The seasons are spring, break, summer, fall, freezing and winter. The period in October when the trees are shedding their leaves and the lakes are freezing over is known as the freeze.
The other period is when the snow melts. At this time the ground looks bare. This season is called breakup season and it can last for months until all the ice on the lake has melted. The break is also identified by the longer days and shorter nights.
flora
flora
It consists mainly of coniferous forest and trees such as larch, spruce, birch, aspen, spruce and pine. Tree cover in most parts of the forest is extensive and narrow, forming a mossy undergrowth canopy.
trees
Trees
Coniferous trees (firs, pines and larches): These trees maintain their green color to ensure that they use the minimum available sunlight and to start the process of photosynthesis early.
Deciduous Trees: Most deciduous trees do not grow in the harsh conditions of boreal forests. However, some manage to grow.
fungi
Fungi: Fungi are saprophytic and get enough nutrients from the many branches and dead trees found within the forest. Mycorrhizal fungi live in a symbiotic relationship with conifers, thus helping them absorb water and mineral salts, while on the other hand obtaining nutrients from trees.
fungi
lichens and moss
Lichens: Lichens are important to reindeer and caribou found in the forest because these animals feed on them.
Moss: Moss plants like sphagnum suck up a lot of water from the forest floor, forming a swampy ground under the trees.

fauna
fauna
Mammals: They are herbivores such as moose, caribou, deer, mouse, etc. These are well adapted to survive in harsh environments such as hibernation and carnivore attacks through camouflage.
Birds: These are mainly seen around the short spring and also during the summer. Most migrate before the cold, but some remain.
