Question: What country does Taiga cover most of?
About the article "Finland", section "Biodiversity".

Candidate passages:
Taiga - the most extensive natural area of Russia - stretches from the western borders of Russia to the Pacific.
It occupies the territory of the Eastern Europe and West Siberian plains to the north of 56 ° -58 ° N and most of the territory east of Yenisei River taiga forests reach the southern borders of Russia in Siberia taiga only accounts for over 60% of Russia.
In the north-south direction the eastern taiga is divided (east of the Yenisei River), with a continental climate, and west, with a milder climate, in general, the climate zone is moist, moderately warm (cool in the north) in the summer and harsh winter, there is a steady snow cover in the winter.
In the latitudinal direction the taiga is divided into three subzones - northern, middle and southern taiga.
In the western taiga dense spruce and fir forests on wetlands alternate with pine forests, shrubs and meadows on the lighter soils.
Such vegetation is typical of the eastern taiga, but it plays an important role not fir and larch.
Coniferous forest, however, does not form a continuous array and sparse areas of birch, alder, willow (mainly in river valleys), the wetlands - marshes.
Within the taiga are widespread fur-bearing animals - sable, marten, ermine, moose, brown bear, wolverine, wolf, and muskrat.
In the taiga is dominated by podzolic and cryogenic taiga soils, characterized by clearly defined horizontal structure (only in the southern taiga there are sod-podzolic soil).
Formed in a leaching regime, poor humus om.
Groundwater is normally found in the forest close to the surface, washing calcium from the upper layers, resulting in the top layer of soil of the taiga discolored and oxidized.
Few areas of the taiga, suitable for farming, are located mainly in the European part of Russia.
Large areas are occupied by sphagnum marshes (here is dominated by podzolic-boggy soil).
To enrich the soil for agricultural purposes should be making lime and other fertilizer.
Russian Taiga has the world's largest reserves of coniferous wood, but from year to year - as a result of intensive logging - they decrease.
Development of hunting, farming (mainly in river valleys). 
Taiga is the world's largest land biome, and makes up 29% of the world's forest cover; the largest areas are located in Russia and Canada.
The taiga is the terrestrial biome with the lowest annual average temperatures after the tundra and permanent ice caps.
Extreme winter minimums in the northern taiga are typically lower than those of the tundra.
The lowest reliably recorded temperatures in the Northern Hemisphere were recorded in the taiga of northeastern Russia.
The taiga or boreal forest has a subarctic climate with very large temperature range between seasons, but the long and cold winter is the dominant feature.
This climate is classified as "Dfc", "Dwc", "Dsc", "Dfd" and "Dwd" in the Köppen climate classification scheme, meaning that the short summer (24-hr average 10 °C or more (50 °F) lasts 1–3 months and always less than 4 months.
There are also some much smaller areas grading towards the oceanic "Cfc" climate with milder winters, whilst the extreme south and (in Eurasia) west of the taiga reaches into humid continental climates ("Dfb", "Dwb") with longer summers.
The mean annual temperature generally varies from -5 °C to 5 °C, (23 °F to 41 °F) but there are taiga areas in eastern Siberia and interior Alaska-Yukon where the mean annual reaches down to -10 °C.
(14 °F) According to some sources, the boreal forest grades into a temperate mixed forest when mean annual temperature reaches about 3 °C.
(37 °F) Discontinuous permafrost is found in areas with mean annual temperature below 0 °C, whilst in the "Dfd" and "Dwd" climate zones continuous permafrost occurs and restricts growth to very shallow-rooted trees like Siberian larch.
The winters, with average temperatures below freezing, last five to seven months.
Temperatures vary from −54 °C to 30 °C (-65 °F to 86 °F) throughout the whole year.
The summers, while short, are generally warm and humid.
In much of the taiga, -20 °C (-4°F) would be a typical winter day temperature and 18 °C (64 °F) an average summer day.
The growing season, when the vegetation in the taiga comes alive, is usually slightly longer than the climatic definition of summer as the plants of the boreal biome have a lower threshold to trigger growth.
In Canada, Scandinavia and Finland, the growing season is often estimated by using the period of the year when the 24-hr average temperature is or more.
For the Taiga Plains in Canada, growing season varies from 80 to 150 days, and in the Taiga Shield from 100 to 140 days.
Some sources claim 130 days growing season as typical for the taiga.
Other sources mention that 50–100 frost-free days are characteristic.
Data for locations in southwest Yukon gives 80–120 frost-free days.
The closed canopy boreal forest in Kenozersky National Park near Plesetsk, Arkhangelsk Province, Russia, on average has 108 frost-free days.
The longest growing season is found in the smaller areas with oceanic influences; in coastal areas of Scandinavia and Finland, the growing season of the closed boreal forest can be 145–180 days.
The shortest growing season is found at the northern taiga–tundra ecotone, where the northern taiga forest no longer can grow and the tundra dominates the landscape when the growing season is down to 50–70 days, and the 24-hr average of the warmest month of the year usually is 10 °C (50 °F) or less.
High latitudes mean that the sun does not rise far above the horizon, and less solar energy is received than further south.
But the high latitude also ensures very long summer days, as the sun stays above the horizon nearly 20 hours each day, with only around 6 hours of daylight occurring in the dark winters, depending on latitude.
The areas of the taiga inside the Arctic Circle have midnight sun in mid-summer and polar night in mid-winter.
The taiga experiences relatively low precipitation throughout the year (generally 200–750 mm annually, 1,000 mm in some areas), primarily as rain during the summer months, but also as fog and snow.
This fog, especially predominant in low-lying areas during and after the thawing of frozen Arctic seas, means that sunshine is not abundant in the taiga even during the long summer days.
As evaporation is consequently low for most of the year, precipitation exceeds evaporation, and is sufficient to sustain the dense vegetation growth.
Snow may remain on the ground for as long as nine months in the northernmost extensions of the taiga ecozone.
In general, taiga grows to the south of the 10 °C July isotherm, but occasionally as far north as the 9 °C (48 °F) July isotherm.
The southern limit is more variable, depending on rainfall; taiga may be replaced by forest steppe south of the 15 °C (59 °F) July isotherm where rainfall is very low, but more typically extends south to the 18 °C (64 °F) July isotherm, and locally where rainfall is higher (notably in eastern Siberia and adjacent Outer Manchuria) south to the 20 °C (68 °F) July isotherm.
In these warmer areas the taiga has higher species diversity, with more warmth-loving species such as Korean Pine, Jezo Spruce, and Manchurian Fir, and merges gradually into mixed temperate forest or, more locally (on the Pacific Ocean coasts of North America and Asia), into coniferous temperate rainforests.
The area currently classified as taiga in Europe and North America (except Alaska) was recently glaciated.
As the glaciers receded they left depressions in the topography that have since filled with water, creating lakes and bogs (especially muskeg soil) found throughout the taiga.

Since North America and Asia used to be connected by the Bering land bridge, a number of animal and plant species (more animals than plants) were able to colonize both continents and are distributed throughout the taiga biome (see Circumboreal Region).
Others differ regionally, typically with each genus having several distinct species, each occupying different regions of the taiga.
Taigas also have some small-leaved deciduous trees like birch, alder, willow, and poplar; mostly in areas escaping the most extreme winter cold.
However, the Dahurian Larch tolerates the coldest winters in the northern hemisphere in eastern Siberia.
The very southernmost parts of the taiga may have trees such as oak, maple, elm and lime scattered among the conifers, and there is usually a gradual transition into a temperate mixed forest, such as the Eastern forest-boreal transition of eastern Canada.
In the interior of the continents with the driest climate, the boreal forests might grade into temperate grassland.
There are two major types of taiga.
The southern part is the closed canopy forest, consisting of many closely spaced trees with mossy ground cover.
In clearings in the forest, shrubs and wildflowers are common, such as the fireweed.
The other type is the lichen woodland or sparse taiga, with trees that are farther-spaced and lichen ground cover; the latter is common in the northernmost taiga.
In the northernmost taiga the forest cover is not only more sparse, but often stunted in growth form; moreover, ice pruned asymmetric Black Spruce (in North America) are often seen, with diminished foliage on the windward side.
In Canada, Scandinavia and Finland, the boreal forest is usually divided into three subzones: The high boreal (north boreal) or taiga zone; the middle boreal (closed forest); and the southern boreal, a closed canopy boreal forest with some scattered temperate deciduous trees among the conifers, such as maple, elm and oak.
This southern boreal forest experiences the longest and warmest growing season of the biome, and in some regions (including Scandinavia, Finland and western Russia) this subzone is commonly used for agricultural purposes.
The boreal forest is home to many types of berries; some are confined to the southern and middle closed boreal forest (such as raspberry), others grow in most areas of the taiga (such as cranberry and cloudberry), and some can grow in both the taiga and the low arctic (southern part of) tundra (such as bilberry and lingonberry).
The forests of the taiga are largely coniferous, dominated by larch, spruce, fir and pine.
The woodland mix varies according to geography and climate so for example the Eastern Canadian forests ecoregion of the higher elevations of the Laurentian Mountains and the northern Appalachian Mountains in Canada is dominated by balsam fir "Abies balsamea", while further north the Eastern Canadian Shield taiga of northern Quebec and Labrador is notably black spruce "Picea mariana" and tamarack larch "Larix laricina".
Evergreen species in the taiga (spruce, fir, and pine) have a number of adaptations specifically for survival in harsh taiga winters, although larch, the most cold-tolerant of all trees, is deciduous.
Taiga trees tend to have shallow roots to take advantage of the thin soils, while many of them seasonally alter their biochemistry to make them more resistant to freezing, called "hardening".
The narrow conical shape of northern conifers, and their downward-drooping limbs, also help them shed snow.
Because the sun is low in the horizon for most of the year, it is difficult for plants to generate energy from photosynthesis.
Pine, spruce and fir do not lose their leaves seasonally and are able to photosynthesize with their older leaves in late winter and spring when light is good but temperatures are still too low for new growth to commence.
The adaptation of evergreen needles limits the water lost due to transpiration and their dark green color increases their absorption of sunlight.
Although precipitation is not a limiting factor, the ground freezes during the winter months and plant roots are unable to absorb water, so desiccation can be a severe problem in late winter for evergreens.
Although the taiga is dominated by coniferous forests, some broadleaf trees also occur, notably birch, aspen, willow, and rowan.
Many smaller herbaceous plants grow closer to the ground.
Periodic stand-replacing wildfires (with return times of between 20–200 years) clear out the tree canopies, allowing sunlight to invigorate new growth on the forest floor.
For some species, wildfires are a necessary part of the life cycle in the taiga; some, e.g.
Jack Pine have cones which only open to release their seed after a fire, dispersing their seeds onto the newly cleared ground.
Grasses grow wherever they can find a patch of sun, and mosses and lichens thrive on the damp ground and on the sides of tree trunks.
In comparison with other biomes, however, the taiga has low biological diversity.
Coniferous trees are the dominant plants of the taiga biome.
A very few species in four main genera are found: the evergreen spruce, fir and pine, and the deciduous larch.
In North America, one or two species of fir and one or two species of spruce are dominant.
Across Scandinavia and western Russia, the Scots pine is a common component of the taiga, while taiga of the Russian Far East and Mongolia is dominated by larch. 
  The series' main male protagonist, Ryūji is a seventeen-year-old high school student in his second year, class 2-C. Due to heredity, his sanpaku eyes make him look like an intimidating delinquent and causes many misunderstandings.
He lives in a fatherless family with just his mother, and due to this, Ryūji has learned to be self-sufficient.
He is good at cooking and keeping everything in his house clean (to the point of obsession), and also excels at sewing.
He holds a crush on Minori Kushieda, a girl his age in his class.
He has a pet parakeet named "Inko-chan" ("inko" literally means "parakeet" in Japanese).
Ryūji often helps Taiga with domestic chores which she is otherwise unable to perform.
At school, he is known as "the only person able to stop the palmtop tiger", referring to Taiga's nickname.
Due to the misunderstandings due to his looks, as well as how he grew up, he tends to look down on himself.
Despite this, he is rather calm in most situations and is responsible, smart and has great grades, even when compared to Yūsaku Kitamura, his best friend.
In the light novels, he sees a tender side of Taiga Aisaka that she hides from everyone.
In the anime, he is dense when it comes to girls' feelings, especially about things between him, Taiga, Minori and Ami.
While initially seen as intimidating by most others, he makes more friends.
His feelings and relationship to Taiga begin to change as he spends more time with her throughout the series.
Eventually, he and Taiga become a couple.
Taiga is a girl in Ryūji's class, as well as the series' main female protagonist.
She has a well-regulated and beautiful appearance though is unable to stomach company from others.
Due to her often snapping at others in brutal ways and her short stature, she is given the nickname .
Her under-developed body and the added nickname has given her a complex which in turn serves to give her a negative attitude and facial expression.
Essentially, Taiga gets upset easily.
She is also brutally honest, typically when she is lashing out at someone.
Due to her cute looks (described as a doll by Ryūji), she often gets confessions of love by boys, but she turns down every one of them, including Yūsaku Kitamura (which she later regrets).
She is clumsy and tries to hide that too; it seems that only Ryūji has observed it.
Despite coming from a well-to-do family, her life with them is very difficult because of various problems.
She had lived with her father and step-mother and constantly fought with her parents, but she moved out and since then has taken to living on her own.
Since she came from a privileged household, she does not know how to do any domestic chores.
Near the end of the story her father's business goes bankrupt and he runs away, leaving Taiga in the care of her mother who was already remarried and had a new family of her own and with which Taiga has difficulty getting along.
When she meets Ryūji and learns of his domestic talents, she ends up relying on Ryūji to cook for her.
Aside from sleeping in her own house, and going to school, she spends most of her time at Ryūji's house; so much so that she is considered a member of his family.
At the beginning of the story, she is infatuated with his best friend Yūsaku Kitamura and gets nervous every time he appears around her.
Due to this, Taiga and Ryūji team up to help each other get into a relationship with each other's best friend.
Though she treats Ryūji badly at first, her feelings begin to change as she spends more time with him.
They later become a couple.
Minori is a girl in Ryūji's class, and is a close friend to Taiga.
She is also known by the pet name "Minorin" (as a form of friendly affection).
In contrast to the violent nature of Taiga, Minori is always smiling and cheerful.
She is very athletic and is the captain of the girl's softball club at school, though at the same time she holds many part time jobs.
She is a glutton when it comes to food, but is also constantly combating it with dieting, calling herself a "diet warrior".
She gets a thrill out of being scared.
Despite her air-headed tendencies, she is very perceptive, and is one of the few people to see Ryūji for the gentle person he is, and is also not fooled by Ami's acts of innocence.
It is implied that her air-headed tendencies may be a facade, and later revealed that she too loves Ryūji.
She has a younger brother.
Yūsaku is a male student in Ryūji's class, and is his best friend.
He is the vice-president of the student council, the class representative, and captain of the boy's softball club at school.
Yūsaku wears glasses, and has a diligent personality.
He thinks he is poor at talking to girls, though Ryūji observes otherwise.
During his time as the vice-president of the student council, he eventually falls in love with the student council president, Sumire Kanō.
A running gag is that he will appear out of nowhere behind Taiga and Ryūji when they are discussing a "plan of attack" to get their crushes.
Like Minori, he has an unusual personality, but often it is an expression of his friendship and appreciation, though it can easily get out of hand fast.
After his graduation, he goes to study abroad in America, chasing after Sumire Kanō.
Ami is Yūsaku's childhood friend who transfers into his class midway through their second year of high school.
She is very beautiful and even works as a model and is seen as the mature one of the group.
After she transfers schools she temporarily stops modeling.
However, she still continues to go to the gym readily and maintains a slim figure.
She is always kind and generous towards others, though this is merely a deception.
In truth, she is a princess and has an arrogant belief in her own cuteness, a trait that she tries to hide from most others.
During her first meeting with Taiga, Ami shows her true colors, but the tables are turned when Taiga counterattacks by slapping her.
Since then, Ami and Taiga have been enemies, with Ami becoming one of a few who can tease Taiga at will; and Taiga referring to Ami as "Baka-chi" (Stupid Chihuahua).
Ami occasionally sets aside her facade and speaks honestly to Ryūji, and is aware that she is really dark and twisted.
Despite all this, Ami still sometimes envies Taiga since she can always be honest.
Ami toys with developing a love interest in Ryūji, asking him if he would love her real self and give her a second chance.
She has a deep understanding of the relationship situation going on between Minori, Ryūji, Taiga, and herself.
Yasuko is Ryūji's thirty-three-year-old mother, though she refers to herself as eternally twenty-three; she has large, F-cup-sized breasts.
Though she tells Ryūji his father died before he was born, the truth is they were never married; he left her before Ryūji was born, and she raised her son by herself.
She works at a hostess bar named Bishamontengoku where she goes by the name , and singlehandedly supports her two-member family financially.
However, she has a childish personality and since she works, she entrusts the household chores to Ryūji.
She instantly takes a liking to Taiga and already regards her as a member of her family, getting depressed when Taiga will not appear for dinner.
However, she does get angry when woken up too early since she usually comes home very late.
Despite the childish, air-headed behavior, Yasuko proves to have a rather good insight of other people.
Yuri is the 29-year-old homeroom teacher of Ryūji's class, though she turns thirty in the fifth volume of the light novels.
She likes to do things at her own pace and is timid towards Taiga's way of speaking out.
Since her twenties are almost over, Yuri is in a hurry to get married soon and she even tries to dress well so as to be able to get into a relationship quicker.
After she becomes thirty without getting married, she develops a twisted and depressed personality, which is further developed by Taiga because when Taiga talks about her, she emphasizes her single status.
She has an interest in real estate which is sort of a crutch for her single status.
Sumire is the student council president and always manages to get the top grades in school; she is in fact a scholarship student and has horrible eyesight.
She has a strong-minded personality which she depends on to be a figure to those who will follow.
Her younger sister is Sakura and her parents own a supermarket.
She later studies abroad in America as she wants to become an astronaut, and because of this, she rejects Yūsaku's confession and conceals her own feelings, so that he will not pursue her in America.
Sakura is Sumire's younger sister who attends the same high school as Sumire though her grades are horrible.
She can unconsciously flirt with people, and like her sister, she hates snakes.
She later starts going out with Kōta.
Kōta is a first-year student who is the main character to "Toradora Spin-off!".
He is generally unhappy about his life.
He works on the student council in general affairs, and gets good grades.
When first seen he has a completely mistaken idea what the term "palmtop tiger" refers to, and develops an insane crush on Taiga.
He later develops a crush on Sakura, and eventually succeeds in starting a romantic relationship with her.
Hisamitsu is a male student in Ryūji's class who wears glasses.
He was also in Ryūji's class the previous year and is on good terms with him.
He is first seen in chapter 4 of the light novels/manga and episode 2 of the anime, when he pairs up with Minori Kushieda for basketball warmup.
Noto begins to develop feelings for Maya Kihara following an argument they had during the class winter ski trip.
Kōji is a male student in Ryūji's class who has long hair and is on good terms with him.
He is regarded as a class 'idiot' and that opinion is deepened by his poor school marks and overly energetic behavior.
He is first seen in chapter 5 of the light novels, chapter 6 of the manga, giving first testimony that Ryūji Takasu and Taiga Aisaka look like a couple.
His childish pranks often target Taiga and he has been the victim of her violent outbursts.
Despite his overly energetic behavior, he is revealed to have a girlfriend later on in the series.
Maya is a female student in Ryūji's class who often hangs out with Nanako.
She is a kogal and the center of the 'stand out group' of girls of class 2-C. She is first seen in chapter 4 of the light novels/manga and episode 2 of the anime, when she pairs up with Yūsaku Kitamura for basketball warmup.
She has a crush on Yūsaku, and she circuitously opposes the idea of Taiga and Yūsaku being a couple, and wants Taiga and Ryūji to be together.
Nanako is a female student in Ryūji's class who often hangs out with Maya and Ami.
Kuroma is the thirty-four-year-old unmarried gym teacher at Ryūji's school.
He enjoys strength training and improving his muscle mass.
