The Arctic climate is classified as being either High Arctic Zone with the most severe conditions or Low Arctic Zone which is more conducive to life and land may have 90% or more vegetation compared to typically less than 5% for the high classification. Many fungi reproduce with fruiting bodies, a spore-bearing structure produced above soil or a food source. We have added a link to an to our road maps section. The benefits of trees can be grouped into four categories; social, community, environmental, and economic benefits.
Intrepid tourists, encouraged by the mild weather, passed by in heavily laden vehicles and waved. What will become of the countless birds and animals that depend on one or both environments?

The beluga Belugas Delphinapterus leucas move in groups of hundreds of individuals, mainly in the cold and shallow waters of the Arctic Ocean and the North Atlantic. Giant trucks raced northward carrying cable, pipes, prefab buildings. Beyond lie the barren lands of the North Slope, ending at the industrial arctic-coast hamlet of Deadhorse and the oil fields of Prudhoe Bay—the only reason this road is here at all. It is found at high elevations and high latitudes.
A tropical forest densely packed with 12-foot-tall trees with flared trunks and curved branches of needle leaves — Dr. These latter two lines are not identical, but are fairly close to one another.

As a result, both tundra and boreal forests are undergoing massive physical and biological shifts. The alpine tree line boundary is seldom abrupt: it usually forms a transition zone between closed forest below and treeless alpine tundra above. This can include geothermal exposure associated with hot springs or volcanoes, such as at ; high soil acidity near ; high salinity associated with or ; or ground that is saturated with groundwater that excludes oxygen from the soil, which most tree roots need for growth. But there are other meanings.
