what biomes can exist next to each other

Earth is a truly remarkable place. It's habitation to everything from vast barren deserts and dense tropical rainforests to coral reefs and high alpine meadows.

But have you always stopped to wonder how many different biomes there are on our planet?

In this article, we'll discuss the 26 incredible types of biomes that you can discover across the world. Nosotros'll explain what makes a biome a biome, and we'll clue you lot into the various plants and animals that phone call each of these dissimilar ecosystems home.

What is a Biome?

The word 'biome' might seem elementary plenty, but at that place's actually quite a chip of disagreement among researchers about what the give-and-take actually means.

Unlike organizations take their own definitions for what a biome is, however, they all finer state that a biome is an area with a shared climate that can support a specific group of flora and fauna.

This definition seems uncomplicated enough. But the problem is that it'south hard to distinguish the discussion 'biome' from words and phrases similar 'ecoregion' and 'ecological zone.'

Depending on who you ask, a biome might be divers as a collection of ecoregions or ecological zones. These ecoregions also contain ecosystems and these ecosystems contain dissimilar types of habitats. Just, again, this is even so a thing of some fence in various scientific circles and some researchers don't make a distinction between 'biome' and 'ecoregion.'

To keep things simple, in this article, nosotros're going to focus on how the Globe Wide Fund for Nature (WWF) classifies biomes. The organization start started classifying biomes with its Global 200 project. It lists 26 types of biomes (these are called ecoregions in some WWF publications) that nosotros'll hash out here.

26 Spectacular Types of Biomes of the World

On a planet with tens of millions of constitute and animal species, classifying different parts of the Earth past their flora, animate being, and climate isn't easy. Thankfully, some dedicated scientists have washed the hard piece of work for us and nosotros now have this listing of the 26 types of biomes.

Up next, we'll take a closer look at the 26 biome types equally defined by the WWF. That style yous can get an expert in all things global environmental.

one. Terrestrial Biomes

Our offset major grouping of biomes is the terrestrial biomes. These biomes all encompass plant and brute communities that exist on land. So, without further ado, hither are the xiv terrestrial biomes on our planet.

1.ane Deserts and Xeric Shrublands

Offset up on our list is the deserts and xeric shrublands biome. This biome exists in big swaths across the globe and it includes everything from the Australian Outback to the Sahara Desert.

Here, atmospheric precipitation amounts are usually less than ten inches (25 cm) each twelvemonth. Yet, these deserts tin either be hot deserts, such as the Mojave, or common cold deserts, such equally the Gobi.

Most of the vegetation in this biome is well-adjusted to life in an arid surroundings. Common constitute species include various succulents. Many of the biome's nearly iconic animal species, such as the diverse types of camels, are also able to survive for days or weeks without h2o.

one.2 Tropical and Subtropical Moist Broadleaf Forests

The tropical and subtropical moist broadleaf forests biome includes much of what nosotros might normally telephone call a tropical rainforest. Y'all can find this biome across the tropical latitudes and it includes places similar the Amazon Rainforest and the jungles of southeastern Asia.

A defining feature of these forests is their high annual rainfall levels. Most of these forests receive more than 79 in (200 cm) of precipitation each year, and sometimes a whole lot more.

These forests are some of the well-nigh biodiverse places on Globe as their high wet levels and hot temperatures allow for a plethora of flora and fauna to thrive. Tropical forests usually accept dense leafage and they can back up an assortment of amazing animals, such as diverse types of big cats.

1.3 Tropical and Subtropical Dry Broadleaf Forests

Tropical and subtropical dry broadleaf forests are often plant in areas side by side to tropical rainforests. These regions, which include much of southern Mexico and the Indian subcontinent, take warm year-round temperatures.

The departure betwixt tropical and subtropical dry broadleaf forests and tropical rainforests is that the dry forests have a prolonged annual dry season. As a result, they tend to be slightly less biodiverse than tropical forests.

Even so, this biome is home to a beautiful collection of flora and fauna. You tin often find various types of monkeys every bit well as an incredible assortment of birds in these dry out forests.

i.four Tropical and Subtropical Coniferous Forests

The tropical and subtropical coniferous forests biome is institute primarily in North America, Primal America, and in high-pinnacle areas of s-cardinal Asia. Most of these forests are found in Mexico, specially in the country's Sierra Madre del Sur and Sierra Nevada mount ranges.

Unlike the other tropical and subtropical forest biomes, this biome is dominated by coniferous trees. They ordinarily get relatively low levels of precipitation and they often experience colder temperatures than other nearby biomes.

Vegetation in this biome is dominated by a thick awning of coniferous trees, which prevents sunlight from reaching the forest floor. As such, this biome ofttimes features a big number of fungi and fern species.

1.five Temperate Broadleaf and Mixed Forests

The temperate broadleaf and mixed forests biome is one of the most widespread biomes on the planet. Information technology's found throughout the bulk of eastern N America, western Europe, east asia, southern South America, and eastern Commonwealth of australia.

A cardinal characteristic of these forests is that they experience a substantial variation in temperature and precipitation throughout the year. Many of these forests have four distinct seasons.

Tree species in these forests tin vary, but they normally include various oaks, birches, beeches, and even maples. Wild animals varies wildly throughout the temperate broadleaf and mixed forests, too, but dissimilar types of squirrels, deer, chamois, and conduct tin can are common.

i.6 Temperate Coniferous Forests

Temperate coniferous forests are very similar to tropical and subtropical coniferous forests in terms of their wood cover. However, they exist at higher latitudes in places such equally the western Us and Canada, Fundamental Asia, and coastal Norway.

Most of these forests feel warm summers, though their winters can vary from mild in coastal locations to common cold in inland areas. Depending on the region, these forests can receive big amounts of winter snowfall, as well.

The major tree species in these coniferous forests include everything from cedar, spruce, pine, and fir, to towering redwoods and behemothic sequoias. Animal species can include elk, moose, deer, bears, and bobcats.

ane.seven Boreal Forests and Taiga

Boreal forests and taiga is a biome that'due south unique to the northern latitudes. This biome is constitute throughout the subpolar regions in N America, Europe, and Asia, peculiarly in northern Canada and Siberia.

In this biome, food-poor soils, cold temperatures, and high levels of snow limit species richness. Boreal forests and taiga can back up stands of coniferous trees and some deciduous trees, like birches, poplars, aspens, and cottonwoods.

Additionally, boreal forest and taiga are dwelling house to a number of iconic animal species, such equally reindeer, arctic foxes, snowshoe hares, brownish bears, lynx, and moose. Occasionally, polar bears volition wander into the taiga, but they are mostly found in the tundra.

ane.viii Tropical and Subtropical Grasslands, Savannas, and Shrublands

The tropical and subtropical grasslands, savannas, and shrublands is one of the largest biomes by total state area. It is found throughout much of sub-Saharan Africa, northern Australia, and subtropical Southward America. This biome is also found in parts of Hawaii.

Near of this biome is dominated past areas with a semi-arid climate where forest embrace is limited. This includes areas similar the Serengeti in eastern Africa and the tropical savannas of the Kimberly in Australia.

Despite the often arid nature of much of this biome, it is quite biodiverse. Major tree species include the baobab and the acacia. Meanwhile, major beast species include everything from zebras and wildebeest in sub-Saharan Africa to the Pampas deer and capybara in South America.

1.9 Temperate Grasslands, Savannas, and Shrublands

The temperate grasslands, savannas, and shrublands are found throughout North and Due south America, Asia, eastern Europe, and southeastern Commonwealth of australia. They are more than ordinarily known as the prairies in N America, the steppe in Asia, and the pampas in South America.

About of these grassland, savannas, and shrublands are dry areas that experience broad temperature fluctuations. The state is generally tree-free. Rather, this biome is dominated by grasses and other drought-tolerant shrubs.

Animal species vary by specific location. Just you can observe buffalo in the North American prairie, antelopes and kiangs in the steppes of central Asia, and guanco in the Pampas of Due south America.

1.10 Flooded Grasslands and Savannas

Flooded grasslands and savannas is 1 of the smallest biomes in the world by total land expanse. This biome is constitute simply in minor areas of North America, S America, Asia, and Africa. Information technology includes famous locations such as the Everglades of Florida and the Pantanal in Brazil, Paraguay, and Bolivia.

As its proper noun suggests, the flooded grasslands and savannas biome features wetlands that receive high levels of rainfall. Although this biome covers only a small portion of the Globe'due south surface, information technology plays a disquisitional function in supporting the migration of endless bird species.

For case, Florida'southward Everglades are dwelling to over 300 bird species while the Pantanal is dwelling house to over 700 bird species. Other notable animals found in this biome include alligators, caimans, marsh deer, bush-league dogs, tapir, capybaras, and giant anteaters.

ane.11 Montane Grasslands and Shrublands

One of the few biomes that's found only at high elevations, the montane grasslands and shrublands biome is a unique collection of flora and fauna that thrives in harsh climates. This biome is institute in South America, cardinal Asia, parts of Africa, and throughout New Zealand.

Arguably the most famous example of these montane grasslands and shrublands is that of the páramo in Southward America. The páramo is fairly moisture and cold, though there are some slightly drier montane grasslands plant in the Ethiopian Highlands.

Ascendant plant species in this biome include grasses, shrubs, and acacias. You generally won't find many trees in this biome, but you may notice some stands of trees in nearby tropical savannas and grasslands. Wild fauna species that are unique to this biome include the northern pudú (the world's smallest deer) and the Ethiopian wolf.

one.12 Tundra

The tundra is an incredible biome found only in the most northerly and southerly latitudes on the planet. It'due south defined every bit a treeless polar desert and y'all tin feel information technology just in Scandinavia, Alaska, Russia, Greenland, Iceland, Canada, and the sub-Antarctic islands.

In the tundra, only the heartiest of plants and animals tin survive. This biome features small heaths, sedges, and dwarf shrubs, though in that location are besides areas of bare stone and minimal vegetation cover.

Many of the species constitute in the taiga can also be found in the tundra. However, the northern tundra is also domicile to muskoxen and polar bears. The southern tundra, on the other hand, is constitute primarily in South Georgia, the Kerguelen Islands, and the South Sandwich Islands. These islands are domicile to various penguin species, such as the royal penguin.

one.13 Mediterranean Forests, Woodlands, and Scrub

Although its name might propose that it's only found around the Mediterranean, the Mediterranean forests, woodlands, and scrub biome is located in various hot and dry locations around the world. For the most part, this biome is located in coastal places, like southern California and southern South Africa, that experience hot, dry out summers and balmy, rainy winters.

This biome is sometimes referred to every bit chaparral, particularly in California, and as matorral in South America. The vegetation in this biome can form mosaics where patches of differing vegetation are seamlessly intermixed with each other.

While some areas of this biome are mostly grasslands, y'all tin oftentimes detect stands of oak woodlands, especially in riparian areas. Much of this biome also experiences regular wood fires, which are critical for maintaining the long-term health of its many ecosystems.

1.14 Mangroves

Plant forth tropical and subtropical coastlines, mangroves are a unique blazon of forest that thrives in waterlogged and salty soils. You tin see mangroves in intertidal zones throughout the lower latitudes. The virtually famous examples are found in places like the Philippines and Vietnam.

Simply a select number of tree species can thrive in the salty soils of the world's mangroves. Researchers gauge that there are only about sixty tree species that live in mangroves, such equally the red mangrove, mangrove palm, and black mangrove.

Unfortunately, mangroves are at loftier take a chance of destruction due to human development. Since mangroves exist in coastal areas, many accept been damaged, destroyed, or removed entirely in guild to build littoral properties and to develop port facilities around the world.

two. Freshwater Biomes

In addition to terrestrial biomes, the WWF as well classifies biomes as either freshwater or marine. There are vii types of freshwater biomes, each of which tin exist establish in various lakes, rivers, and streams around the world.

2.i Big Rivers

The large rivers biome is found in some of the globe's biggest rivers. This includes high-flow rivers such every bit the Colorado and the Mississippi in N America every bit well as the Yangtze in Cathay and the Congo in sub-Saharan Africa.

At that place are likewise many fish species in these rivers to perhaps proper noun hither. But many of these large rivers have owned fish species, such as the slightly electrified elephantfishes of the Congo River.

2.2 Large River Headwaters

While the large rivers biome encompasses much of the world's major rivers, the large river headwaters biome includes only their headwater areas. These headwater areas often back up unique fish species that are adapted to life in the mountainous areas where major rivers originate.

This biome primarily includes the waters of the Upper Amazon, the Congo Bowl Piedmont, and the Mississippi Piedmont, among other areas. The species that are adjusted to life in these cold, fast-moving waters help create a freshwater surroundings that supports countless ecosystems downstream.

2.3 Big River Deltas

River deltas are the sediment-filled areas at the mouth of a river, right before information technology reaches the sea, lake, or body of water where it terminates. The big river delta biome primarily includes the deltas at the mouths of the world's major rivers, such as the Nile, Amazon, Orinoco, Lena, and Volga rivers.

Almost river deltas are incredibly biodiverse areas. This is particularly true when it comes to rivers that terminate in the bounding main considering the mix of salt and freshwater in these environments creates unique ecosystems where plants and animals tin thrive.

One of the world'due south largest river deltas is that of the Niger River. The Niger actually has two deltas (i inland and 1 coastal), both of which are hotspots for biodiversity.

2.iv Small Rivers

When we think of biodiverse freshwater ecosystems, we often picture huge rivers and lakes. Even so, the small rivers biome includes some of the richest freshwater ecosystems in the temperate and tropical latitudes.

This biome is institute all over the earth, including in places such as New Caledonia, Madagascar, and the Greater Antilles. It mostly consists of smaller streams, like those in southwestern Commonwealth of australia, that are hubs for biodiversity.

two.v Large Lakes

The earth's largest lakes, such as Lake Baikal and the Peachy Lakes, contain fascinating ecosystems. Large lake systems, like the Rift Valley Lakes in East Africa, too fall under this biome.

Each of these lakes contains different flora and creature, only they all share similarly loftier levels of endemism. For example, approximately lxxx per centum of the animal species in Lake Baikal are endemic, including the amazing Baikal seal.

2.6 Minor Lake Ecosystems

Small lakes may not seem like biodiversity hotspots, merely they are habitation to amazing ecosystems. This is particularly true in tropical areas where the sheer number of fish species that can exist in a minor lake is aught short of astounding.

For instance, Lake Kutubu in Papua New Guinea is about 12 miles (19 km) long and 2.8 mi (four.5 km) wide, but it contains 13 endemic fish species. Meanwhile, Lake Lanao in the Philippines is 21 miles (33 km) long and 12 mi (20 km) wide, only it's habitation to approximately 18 owned fish species.

2.seven Xeric Basins

The concluding freshwater biome is the xeric basins. Interestingly, these are areas with relatively little permanent surface water. Rather, these xeric basins are home to a multitude of freshwater springs, which assistance life thrive in otherwise arid environments.

Major xeric basins are located in places similar cardinal Australia, the Chihuahuan Desert, and the Anatolian region of Turkey. For example, the Cuatro Ciénegas Basin in Mexico is home to three owned turtle species, 8 owned fish species, and multiple endemic species of snails, despite the fact that it's located in the middle of the desert.

3. Marine Biomes

Final but not to the lowest degree, we have the marine biomes. These biomes are too water-based, just they include only bodies of saltwater. The Earth'southward oceans are unbelievably biodiverse, and each of these 5 marine biomes contains a superb array of flora and fauna.

3.1 Polar

When you lot picture polar oceans, you might imagine cold, dark waters where little life tin can thrive. All the same, the polar oceans are some of the nigh biodiverse areas in the world due to their depression temperatures and depression salinity levels, which tin support a truly astonishing corporeality of plankton.

As a result, the polar oceans, which include the Arctic Ocean, Antarctic ocean, and their surrounding seas, are dwelling house to thousands of species that rely on plankton—either straight or indirectly—for survival.

This includes baleen whales like the humpback, blue whale, and bowhead whale, as well as penguins, orcas, and dozens of types of seals. The polar oceans are too domicile to incredible bird species, such as various albatrosses, petrels, terns, and fulmars.

iii.ii Temperate Shelf and Seas

Located in the waters and along the coastlines of the temperate regions, the temperate shelf and seas biome is i of the about bioproductive areas on the planet. This includes the Mediterranean, temperate North Atlantic, and temperate N Pacific oceans.

Much of this biome is relatively shallow as most continental shelves are no more than 490 feet (150 g) deep. Here, you tin also find some of the world's most important temperate estuaries, such as the Chesapeake Bay, which serve as vital habitats for migratory birds and marine life.

three.3 Temperate Upwelling

The temperate upwelling biome primarily refers to areas along the declension of western N and Southward America where upwelling waters let for an abundance of fish species.

In these areas, which include coastal Peru, Republic of ecuador, Chile, United mexican states, and California, the upwelling of cold, nutrient-rich waters supports enormous populations of fish and seabirds. These areas are home to some of our most important commercial fisheries, too, specially in areas affected by the Humboldt and California currents.

3.iv Tropical Upwelling

The tropical upwelling biome is still another highly bioproductive area that's driven by the upwelling of cold, nutrient-rich waters in littoral environments. This biome is somewhat easy to identify in maps of sea surface temperatures because information technology exists in pockets of uncharacteristically cold waters in tropical seas.

For case, the waters of the Canary Current near the Canary Islands are often colder than they would otherwise exist. Even so, this cold, nutrient-rich h2o is essential for supporting countless fish, bird, and bounding main turtle species.

iii.v Tropical Coral

Finally, we have the tropical coral biome. This aptly named biome includes all of the globe'southward coral reefs, including Commonwealth of australia'south Great Barrier Reef.

Of all of the marine biomes, the tropical coral biome is arguably the most biodiverse. There are thousands of types of coral on our planet, nearly of which are plant in the tropical coral biome. Additionally, these coral reefs back up hundreds of fish species, including many that can't be found anywhere else on Earth.

How Are Biomes Classified?

In this article, we focus on the 26 types of biomes as defined by the World Wide Fund for Nature (WWF). However, this is simply one way of classifying the World's biomes.

Dozens of other biome nomenclature systems exist. While we tin't possibly mention them all hither, we can betoken out some of the major systems that you ought to know about.

For example, NASA (National Aeronautics and Space Assistants) uses the following classification system for biomes:

• Rainforests
• Grasslands
• Coniferous Forests
• Temperate Deciduous Forests
• Deserts
• Tundras
• Shrublands

Additionally, National Geographic uses this arrangement:

• Aquatic
• Grasslands
• Forests
• Deserts
• Tundras

These two systems are adequately basic, simply each organization's broad biome categories can be subdivided into more specific biomes. For example, National Geographic's aquatic biome tin exist subdivided into freshwater and marine and and so further subdivided from there.

Ultimately, there'south no consensus on how we should classify biomes. The definition of each type of biome is also constantly evolving every bit nosotros acquire more about the globe around us.
