Spruce and fir trees are typically found in the boreal forests that lie to the south of the tundra. Fir and spruce are the two most common conifer species in North America. They grow in a variety of habitats, including open woodlands, forests, meadows, and prairies. The two species are closely related and are often confused with each other, but they are not the same species.
Spruce is a deciduous tree, while fir is an evergreen tree. Both species can be distinguished by the shape of their trunks and the number of leaves on their branches. Firs are generally taller and wider than spruces, making them more difficult to distinguish from one another.

Is there trees in the Arctic tundra?
Arctic is warming faster than the rest of the planet. In the summer, it can be as much as 10 degrees Fahrenheit (5 degrees Celsius) warmer than it was in the late 19th century, according to the U.S. National Snow and Ice Data Center (NSIDC).
Arctic has warmed more than twice as fast as any other region on Earth since the mid-1990s, when satellite data began to be collected. And the rate of warming is accelerating. By the end of this decade, Arctic sea ice will be the smallest it has been since satellite records began in 1979.
Are birch trees in the tundra?
Birch or resin birch, and dwarf birch, or dwarf Arctic birch (B. nana), native to most far northern areas of the world, are small alpine and tundra shrubs commonly known as ground birch. Both species have leaves that are almost circular and have been used for thousands of years for their wood and bark.
The bark is used to make a variety of products, including paper, paperboard, rope, cordage, clothing, furniture, bedding, flooring, roofing and other building materials. The bark can also be used as an insecticide and insect repellent, as well as a food source for insects, birds, mammals, reptiles, amphibians, fish and invertebrates.
Does the tundra have evergreen trees?
Evergreen trees at the edge of Alaska’s tundra are growing faster, suggesting that at least some forests may be adapting to a rapidly warming climate, a study published today in the journal Nature Climate Change.
The study, led by researchers from the U.S. Geological Survey (USGS) and the University of California, Santa Barbara (UCSC), found that the growth rate of at-risk forests in Alaska is increasing at a faster rate than the rate at which they are being replaced by new trees.
The study is the first to quantify the extent to which forests are responding to climate change by increasing their growth rates, and it suggests that some of the fastest-growing forests on the planet may already be at risk of being lost to the encroachment of warmer, drier conditions, the researchers .
Why trees are grown in tundra region?
Tundras are characterized by cold climates, short growing seasons, and a thin layer of soil above a permanently frozen layer (the permafrost). Only low-growing plants can survive in the tundra because this gives plants only a very short depth in which to grow roots.
Arctic is much colder, with a mean annual temperature of -20°C (-4°F) and an average annual precipitation of less than 0.5 mm (0.01 inch) per year.
Do pine trees grow in the Arctic?
Scots pine has the widest range of all pine species, extending in the north far beyond the arctic circle. The growing season is short and survival is low, close to the tree limit. Pine is the most widely planted tree in Scotland, and is also the second most commonly planted species in England and Wales.
Highlands, it is found in a wide variety of habitats, including open woodlands, meadows, pastures, hedgerows and woodland edges. The tree is native to Europe and North America, but is now found throughout much of Europe, North Africa and the Middle East.
What are sedges in the tundra?
Sedges are the largest plant group in the state of Alaska with over 150 species. The cotton grass is named for the fluffy mass that develops on the end of its stalks, and it’s the most recognizable tundra sedge.
Sedges can be found in a wide variety of habitats, ranging from the Arctic to the temperate rain forests of the Pacific Northwest. They are found throughout the United States and Canada, as well as in Europe, Asia, Africa, the Middle East, South America, Australia and New Zealand.
Do sedges live in the tundra?
sedges look like grasses, but none of them grow tall. A sedge normally found in the tundra is the arctic cotton. The plant has a stem that is 30 cm high and has white, waxy hairs on the top. The leaves of the cotton plant are about 1cm long and have a yellowish-green colour.
They are covered with a thin layer of white hairs, which are used to protect the leaves from the sun’s rays. These hairs are also used by the plant as a defence mechanism against insects and other predators. Cotton plants are very adaptable and can be grown in a wide range of climates and soils.
