Land Biomes: Every centimetre of land on Earth belongs to a biome. Stand in a Scottish oak woodland, a Saharan sand dune, or an Alaskan tundra plain, and you are inside a vast living system shaped by millions of years of climate, geology, and evolution. Scientists have identified seven major land biomes, each with its own temperature range, rainfall pattern, plant community, and animal life. Together, these seven zones cover the entire terrestrial surface of our planet, from the frozen poles to the steaming equatorial belt.
Understanding land biomes sits firmly within the KS2 Geography curriculum in the UK, where children explore climate zones, natural vegetation, and the relationship between humans and their environment. LearningMole, the UK educational platform founded by former primary school teacher Michelle Connolly, has put together this guide to make that learning as clear and engaging as possible.
Whether you are a teacher planning a geography lesson, a parent supporting home learning, or a curious young explorer, this page covers everything you need: definitions, climate data, wildlife, locations, and the connections between each biome and our changing planet.
One question children always ask is, ‘Which biome do we live in?’ The answer for most of the UK is the temperate deciduous forest, and that connection to something local is one of the best ways to make global geography feel real. As you read through each of the seven land biomes below, look for the clues that link distant places back to what you might see in your own garden, local park, or nearest woodland. The world is far more connected than it first appears, and biomes are the reason why.
The seven land biomes, in order from the poles to the equator, are: Tundra, Taiga, Temperate Forest, Grassland, Desert, Savanna, and Tropical Rainforest. That’s a lot to recall, so here is a simple memory trick.
Try this mnemonic: Two Tigers Tend Great Desert Savanna Treks.
Each first letter matches a biome in rough pole-to-equator order: Tundra, Taiga, Temperate Forest, Grassland, Desert, Savanna, Tropical Rainforest. Say it a few times, and the sequence sticks.
It is also worth knowing that some textbooks list five or six biomes instead of seven. This usually happens because the Savannah is grouped with the grassland, or because a different classification system is used. The seven-biome model is the most widely taught at the KS2 level and the one used in this guide. Scientists do not all agree on exact boundaries, and that is part of what makes biogeography such a fascinating area of study.
The biome map below shows how these seven zones are distributed across the continents. Each biome is shaped primarily by two things: average annual temperature and average annual rainfall. As you move from the poles toward the equator, or from the coast into a continental interior, those two variables change, and the biome changes with them.
Tundra is the coldest land biome on Earth. Temperatures can plunge below -50°C in winter, and even in summer, the ground rarely warms above 10°C. Rainfall is very low, typically under 250 mm per year, which puts Tundra in the same precipitation category as many deserts, but the biting cold and short summers prevent the water from evaporating, leaving the landscape boggy and waterlogged when it thaws.
The defining feature of a tundra is permafrost — a permanently frozen layer of soil that begins just below the surface. Permafrost prevents tree roots from penetrating deep enough to anchor tall plants, which is why Tundra is treeless. Only low-growing mosses, lichens, short grasses, and herbs survive here, and they do so in bursts during the brief Arctic summer.
Wildlife has adapted brilliantly to these extremes. Polar bears and Arctic foxes carry thick layers of insulating fat and fur. Lemmings, musk oxen, and reindeer graze the sparse summer vegetation. Many bird species migrate to the tundra in summer to breed, then fly south as temperatures drop again. Tundra is found in northern Russia, Alaska, Canada, Greenland, and Iceland, as well as on high mountain summits at lower latitudes.
The word tundra comes from the Finnish ‘tunturi’, meaning treeless plain. That is exactly what it is.
Moving south from the tundra, the permafrost gives way to a different world: the Taiga, also known as the Boreal Forest or Coniferous Forest. This is the largest land biome on Earth, stretching in a vast band across northern Canada, Russia, Scandinavia, and Alaska. It covers more land area than the Amazon and Congo rainforests combined.
Taiga is characterised by its dense forests of coniferous (cone-bearing) trees: pine, fir, spruce, and cedar. These trees have evolved needle-like leaves that shed snow easily and remain green year-round, ready to photosynthesise during the short but brighter summers. Temperatures range from about -40°C in winter to 20°C in summer, and the growing season is limited to two or three months.
The name Boreal comes from Boreas, the Greek god of the north wind. That tells you something about the conditions. Despite the harsh climate, Taiga supports more wildlife than Tundra: wolves, moose, bears, lynxes, beavers, elk, and countless bird species. Many animals survive winter by hibernating or developing exceptionally thick fur.
Taiga is a crucial global carbon store. The vast forests lock up enormous quantities of carbon in both trees and soil. As climate change warms the northern latitudes faster than the global average, scientists are watching the Taiga closely.
The UK sits within the temperate deciduous forest biome. That means the oak woodlands of England, the birch forests of Scotland, and the hedgerow-lined fields of Wales all belong to the same global biome classification as forests in eastern North America, parts of Western Europe, China, and Japan.
Temperate forests experience four distinct seasons: cold winters, mild springs, warm summers, and cool autumns. Annual rainfall sits between 750 mm and 1,500 mm, spread fairly evenly across the year. Temperatures range from around -30°C in the coldest continental areas to 30°C in summer, though in the UK the range is far milder.
The defining plants are deciduous trees — trees that shed their leaves in autumn and regrow them in spring. Oak, birch, alder, willow, beech, and maple are typical examples. Losing leaves in winter reduces water loss at a time when the ground may be frozen and water hard to absorb. When the leaves fall and decompose, they create a rich, dark soil that makes temperate forest regions among the most agriculturally productive on Earth.
Wildlife is diverse: deer, foxes, squirrels, badgers, woodpeckers, owls, and hedgehogs all share this biome. Deciduous forests were once far more extensive across the UK, but centuries of farming and development have reduced them dramatically. Many UK conservation projects now focus on replanting native deciduous woodland to restore habitat and absorb carbon.
Grasslands receive enough rainfall to support grasses and low herbs, but not enough to sustain forests. Annual precipitation typically sits between 250 mm and 750 mm. With too little rain for trees to establish and periodic dry-season fires burning off any woody plants that try, grass dominates.
This biome goes by different names in different places. In North America, it is called the Prairie; in Central Asia, the Steppe; in South America, the Pampas or Pampa; in South Africa, the Veld. The name changes, but the ecology is broadly similar: vast open plains, rich dark soil, and enormous herds of grazing animals.
Grasslands support some of the most productive agriculture on Earth. The deep, fertile soils of the North American prairie and the Ukrainian steppe grow much of the world’s wheat, maize, and soya. Bison, elephants, zebras, antelope, hawks, and owls are among the many species found here. Grasslands cover large areas of Africa, North America, Central Asia, Australia, and parts of South America.
The desert is defined by its aridity rather than its heat. A desert is any region that receives less than 250 mm of rainfall per year, which means that cold deserts exist as well as hot ones. Antarctica is technically a desert. The Atacama in South America is one of the driest places on Earth. The Sahara in North Africa is the world’s largest hot desert.
What makes the desert biome so extreme is the combination of very low rainfall and wide temperature swings. In hot deserts, daytime temperatures can exceed 50°C while nights drop below freezing. This dramatic range is because the dry air and lack of cloud cover provide no insulation, allowing heat to escape rapidly after dark.
Plants and animals here have made extraordinary adaptations. The cactus stores water in its thick stem, coats itself in a waxy layer to prevent evaporation, and uses spines to protect its water reserves from thirsty animals. Camels famously store fat in their humps, which can be metabolised for energy and water. Fennec foxes have enormous ears to release body heat. Reptiles, which regulate their own temperature behaviourally, thrive here by basking and burrowing at the right times of day. Hot deserts are found across North Africa, the Middle East, Central Asia, Australia, and parts of the Americas.
The Savanna is sometimes called tropical grassland, and shares features with both grassland and tropical forest biomes. It receives more rainfall than a standard grassland, typically between 500 mm and 1,300 mm per year, but this is concentrated in a distinct wet season. During the long dry season, grasses turn brown, and fires sweep through, preventing dense forest from establishing.
The result is a landscape of tall grasses with scattered trees — acacia being the most recognisable in Africa. The Savanna covers roughly half of Africa and large areas of northern Australia, southern India, and South America. It is home to some of the most iconic wildlife on Earth: lions, leopards, cheetahs, giraffes, zebras, elephants, baboons, wildebeest, eagles, and ostriches.
The Savanna has the fastest land animals on Earth. The cheetah, capable of reaching 100 km/h in short bursts, evolved here to catch prey across open ground. Many Savanna animals have long legs for exactly this reason: speed and the ability to see over tall grass are survival advantages in a landscape with few places to hide.
The tropical rainforest is the most biodiverse biome on Earth. Scientists estimate it contains more than half of all plant and animal species on the planet, despite covering less than ten per cent of its land surface. This extraordinary concentration of life is possible because the rainforest receives abundant rainfall year-round, typically between 2,000 mm and 10,000 mm, and temperatures remain consistently warm, usually between 20°C and 34°C.
There is no true dry season. Trees keep their leaves year-round, forming a dense canopy so thick that only around two per cent of sunlight reaches the forest floor. The canopy itself is a habitat: monkeys, sloths, tree frogs, parrots, toucans, and thousands of insect species spend their entire lives in the treetops, rarely descending to the ground.
On the forest floor, decomposition is extraordinarily fast in the warm, wet conditions. A leaf fallen from a canopy tree may completely break down within weeks. This rapid nutrient cycling means rainforest soils are actually quite poor. Remove the trees, and the nutrient system collapses. This is one of the reasons that converting rainforest to farmland often produces soil that is exhausted within a few years.
Tropical rainforests are found in South and Central America (the Amazon basin), Central Africa (the Congo basin), and across Southeast Asia, southern India, and northeastern Australia. They are disappearing at an alarming rate due to deforestation for agriculture, logging, and cattle ranching.
This table gives you the key climate and wildlife data for each of the seven land biomes at a glance. Use it for revision, lesson planning, or as a classroom display reference.

The single most important factor determining which biome exists in a given location is latitude — the distance from the equator, measured in degrees. At the equator (0°), temperatures are high year-round, and rainfall is often intense. At the poles (90° north and south), temperatures are extreme, and precipitation is very low. As you move between these extremes, the climate changes predictably, and so do the biomes.
This is why you can predict biome type from location on a map. Regions between the Tropic of Cancer and the Tropic of Capricorn (roughly 23° north and south) tend to host tropical rainforests or savannas, depending on rainfall patterns. The subtropical band between 20° and 35° often contains deserts, because these latitudes sit beneath persistent high-pressure systems that block rain-bearing winds. Temperate latitudes between 40° and 60° — where the UK sits at about 51–58° north — support temperate forests and grasslands.
Altitude works in a similar way to latitude. Climb a mountain in the tropics, and you will pass through tropical forest, cloud forest, alpine grassland, and eventually a tundra-like zone near the summit, simply because temperature drops with altitude just as it drops with distance from the equator. This is why some tropical mountain ranges have conditions similar to Arctic environments at their peaks.
“Visualising the world in biomes helps children understand the delicate balance between climate and life on Earth. Once a child grasps that latitude controls temperature, and temperature controls vegetation, the whole map of the natural world starts to make sense.” Michelle Connolly, Founder of LearningMole and a former primary school teacher with over 15 years of classroom experience
The United Kingdom sits within the temperate deciduous forest biome. Our relatively mild climate, four distinct seasons, and moderate year-round rainfall of roughly 600–1,600 mm (depending on region) support exactly the kind of broad-leaved woodland that defines this zone globally. The Lake District, the New Forest, Epping Forest, and the ancient woodlands of Wales and Scotland are all expressions of the temperate forest biome on home soil.
Scotland’s northwest coast and mountain summits approach conditions closer to Taiga or even Alpine Tundra, particularly on the higher Cairngorm plateau. This makes the UK a useful case study: within a relatively small island, children can observe the beginning of a transition between two major biomes simply by travelling north and uphill.
| Biome | Latitude Zone | Far from the Equator | UK Connection |
| Tropical Rainforest | Equatorial (0–10°) | Closest | None directly |
| Savanna | Tropical (10–20°) | Near equator | None directly |
| Desert | Subtropical (20–30°) | Warm belt | None directly |
| Grassland | Temperate (30–50°) | Mid-latitudes | Scottish uplands (partial) |
| Temperate Forest | Temperate (40–60°) | Mid-latitudes | YES — the UK’s own biome |
| Taiga | Sub-polar (50–70°) | Far from equator | Northern Scotland (partial) |
| Tundra | Polar (65–90°) | Furthest | Mountain summits only |
Biome boundaries are not fixed. They shift over decades and centuries in response to the climate. Today, human-driven climate change is accelerating those shifts faster than at any point in recorded history. Understanding land biomes is, therefore, not just a geography exercise; it is an essential context for understanding the environmental challenges of our time.
The Arctic tundra is warming roughly four times faster than the global average. As permafrost thaws, it releases methane and carbon dioxide that have been locked in frozen ground for thousands of years, accelerating further warming. Scientists describe this as a positive feedback loop: warming causes thawing, which causes more warming. The boundary between Tundra and Taiga is already shifting northward as trees gradually colonise previously frozen ground.
In tropical regions, deforestation is removing rainforest faster than it can regenerate. Large areas of cleared forest can shift to a drier, more grassland-like state because the trees no longer release water vapour through transpiration, reducing local rainfall. The Amazon rainforest, which generates its own rainfall system, may be approaching a tipping point where continued deforestation could trigger a permanent shift to a drier biome across large portions of the basin.
For UK primary pupils studying KS2 geography, connecting the biome study to climate change gives the topic real-world urgency. These are not just categories on a map; they are living systems that millions of species, including humans, depend on.
LearningMole provides curriculum-aligned geography resources for KS2 teachers and parents supporting home learning. The land biomes topic connects directly to the KS2 Geography National Curriculum requirements covering physical geography, climate zones, and natural vegetation.
For a related overview of all biome types, including aquatic biomes, LearningMole’s World Biomes article covers freshwater and marine zones alongside terrestrial ones, making it a useful companion resource for broader geography units.

The seven major land biomes are Tundra, Taiga (boreal forest), temperate deciduous forest, Grassland, Desert, Savanna, and Tropical Rainforest. They are classified by climate: primarily average temperature and annual rainfall. Scientists sometimes use different systems, listing five, six, or even more biomes depending on how finely they divide the categories, but seven is the most widely taught classification at KS2 level.
The UK sits within the temperate deciduous forest biome. Our mild temperatures, four distinct seasons, and moderate year-round rainfall match the global definition of this zone. Native woodlands of oak, birch, beech, and ash are the UK’s natural vegetation. Parts of northern Scotland approach conditions associated with the Taiga biome, particularly in upland areas where the growing season is shorter, and conifers are more common.
The Taiga, also called the Boreal Forest, is the largest land biome on Earth. It stretches across northern Canada, Russia, Scandinavia, and Alaska in a continuous belt covering approximately 17 million square kilometres. This is more land area than the Amazon and Congo rainforests combined. Despite its vast size, the Taiga supports relatively low biodiversity because the long, cold winters limit the number of species that can survive year-round.
A biome is a large-scale geographic zone defined by its climate and dominant vegetation type. It can span entire continents. An ecosystem is a smaller, specific community of living organisms interacting with each other and their physical environment. A single biome contains many ecosystems. For example, the Tropical Rainforest biome contains river ecosystems, forest-floor ecosystems, and canopy ecosystems, each with their own food webs and species communities. Think of a biome as the big category and an ecosystem as one example within it.
The Tropical Rainforest has the highest biodiversity of any land biome, meaning it contains the greatest number of different species. Scientists estimate that it is home to more than half of all plant and animal species on Earth, despite covering less than ten per cent of the land surface. This concentration of life is driven by the warm temperatures, abundant rainfall, and year-round growing season, which allow an extraordinary range of ecological niches to develop.
Yes. The ocean is home to aquatic biomes, which scientists generally divide into two main categories: freshwater biomes (rivers, lakes, wetlands, and ponds) and marine biomes (open ocean, coral reefs, and estuaries). The ocean covers around 71 per cent of Earth’s surface, making it by area the largest biome on the planet. Marine biomes are shaped by water temperature, salinity, depth, and light availability rather than by terrestrial climate factors.
Different classification systems use different numbers of biomes. Some scientists group the Savanna with the Grassland because both are dominated by grasses and lack dense tree cover, reducing the total to six. Others combine Tundra and Taiga into a single ‘polar/sub-polar’ category. The World Wide Fund for Nature (WWF) actually identifies 14 distinct land biome types. The seven-biome model is the most widely used in UK primary education because it balances accuracy with manageability for KS2 geography.
Latitude determines how much solar energy a place receives across the year, which controls temperature. Temperature, combined with rainfall patterns, determines which plants can survive, and plants determine which animals can live in an area. The result is a predictable sequence of biomes from poles to equator: Tundra at the poles, then Taiga, then Temperate Forest or Grassland in mid-latitudes, then Desert in the subtropical belt, and Savanna and Tropical Rainforest closest to the equator. Altitude works similarly, which is why mountain summits can have tundra-like conditions even in tropical countries.
The seven land biomes — Tundra, Taiga, Temperate Forest, Grassland, Desert, Savanna, and Tropical Rainforest — are not just categories in a textbook. They are the living architecture of our planet, shaped over millions of years by the relationship between climate, soil, plants, and animals. Each one represents a different set of solutions to the challenge of survival in a particular environment, from the permafrost-locked tundra plains of the Arctic to the steaming, species-packed floors of equatorial rainforests.
For UK children and teachers, the temperate deciduous forest biome brings this global picture home. The oak and birch woodlands of Britain, the seasonal leaf fall, the familiar deer and foxes of local parks and nature reserves: these are our local expression of a biome that extends across much of the Northern Hemisphere. Understanding that connection — between the conker falling from a school playground tree and the ancient processes that created temperate forest biomes — is one of the most rewarding moments in KS2 geography.
As climate change shifts biome boundaries and threatens some of the most biodiverse regions on Earth, teaching children to understand and care about these systems has never been more important. LearningMole’s geography and science resources support exactly this kind of connected, curriculum-aligned learning, giving teachers and parents the tools to make the natural world as engaging as it deserves to be. If you want to explore the aquatic side of the picture, our World Biomes article covers freshwater and marine zones in depth.
