Forest, Boreal
Boreal forests are the northernmost forests in the world. These are vast forests that include 29 percent of all the world's forest area in a belt around the Northern Hemisphere, including Scandinavia, Russia, and Canada. In the United States, boreal forests occur in central Alaska and northeastern Minnesota. Boreal forests are dominated by species of spruce, fir, pine, larch, birch, and aspen. Their forest floors are usually covered with mosses and many species of wildflowers.
The distinguishing climatic features are long winters with five to seven months of snow cover and a short cool summer. July mean temperatures fall between 13 and 18 degrees Celsius (55 to 64 degrees Fahrenheit). If summers are cooler than this temperature range, trees are unable to complete their summer growth cycle, and tundra is the dominant vegetation. If summers are warmer, temperate forest trees such as maples and oaks become dominant.
Boreal forests can be divided into southern and northern zones. Southern boreal forests have a high density of trees 15 to 30 meters (50 to 100 feet) in height and are productive enough to produce timber and fiber for paper pulp. Those southern boreal forests in the interior of North America and Asia, away from the oceans, periodically experience very large, high-intensity crown fires that range from 40,485 to 404,858 hectares (100,000 to 1 million acres). These forests are composed of species that reproduce well after fires, such as jack pine, aspen, and black spruce. Some southern boreal forests change little in species composition over time, even after fire.
Answer:
boreal forest is a type of forest that grows in region of the northern hemisphere with cold temperatures.made up of mostly of cold tolerant coniferous species such as spurce ND fur. Taiga is the Russian term for the boreal or nothern coniferous forest blome, the ecosystem adjacent to the artic tundra. the boreal forest corresponds with regions of subartic ND cold continental climate.long severe winter ( upto six months which means temperature below freezing) ND short summer ( 50 to 100 frost - free days)as is the wide range of temperatures between the lowd of Winter ND high of summers.boreal forest is also known as evergreen forest .the boreal forest is characterized by it's diverse coniferous tree species, animal species,bird species,lakes ND wetlands,the boreal forest covers 30% of cover in world,with the largest regions in Canada ND in Russia.
