Habitat Types: Rainforests, Deserts, Grasslands, Oceans

Rainforest Habitat

Rainforests are one of the most diverse ecosystems on Earth, covering less than 6% of the world's land area but home to over half of all plant species and about 40% of animal species. They require consistent rainfall through much or all of the year. There are two primary types of rainforests: tropical rainforests and temperate rainforests. The former can be further divided into lowland tropical rainforests and mountainous tropical rainforests.

Lowland Tropical Rainforest

Lowland tropical rainforests have an average annual temperature of around 27°C (80°F). These rainforests host numerous endemic species that live only in their specific location due to the unique environmental conditions, including various insects, birds, mammals, reptiles, amphibians, and plants. Some iconic animals include lemurs, sloths, howler monkeys, poison dart frogs, and toucans.

Mountainous Tropical Rainforest

Mountainous tropical rainforests occur above 750 meters (2,460 feet) and usually below 2,500 meters (8,200 feet) elevation. Despite being part of the same vegetation type, mountainous tropical rainforests have different evolving elements from lowland ones due to differences in temperature, humidity, sunlight, soil availability, rainfall patterns, topography, nutrient cycling, and wind conditions. The number of endemic plant species decreases towards higher altitudes in tropical montane forests.

Temperate Rainforest

The temperate rainforest ecosystem occurs between approximately 30°N and 60°S in North America, Europe, Asia, South America, Australia, and New Zealand where water is abundant throughout the year. These regions receive about 2,000 millimeters of precipitation annually. Some well-known examples of temperate rainforests include Oregon, Washington, Vancouver Island, and British Columbia in North America.

Desert Habitat

Deserts account for about 17% of the earth's total land surface. Different desert habitats exist worldwide, such as hot deserts like the Sahara, hot and dry deserts like the Mojave, Mediterranean-type deserts like the Sonoran Desert, and coastal deserts like the Atacama Desert in Chile. Although they are arid regions, many deserts have a rich biodiversity, including unique species adapted to their harsh conditions.

Hot Deserts

Hot deserts are characterized by high temperatures year-round and minimal precipitation. They are home to a variety of plants and animals with unique adaptations to survive in the extreme heat. Some examples of hot desert plants include cacti, yucca, and creosote bushes. Animals include desert tortoises, rattlesnakes, and the Gila monster.

Mediterranean-Type Deserts

Mediterranean-type deserts, also known as chaparral or matorral, are found in Mediterranean climates around the world. They are characterized by hot, dry summers and mild, wet winters. These deserts are home to plants such as oaks, shrubs, and grasses. Animals include bobcats, rattlesnakes, and ground squirrels.

Coastal Deserts

Coastal deserts are unique habitats along the Pacific Ocean. They are characterized by low precipitation, high temperatures, and strong winds. Some plants found in these deserts include cacti, shrubs, and grasses. Animals include the desert tortoise, Gila monster, and various birds of prey.

Grassland Habitat

Grasslands cover about 40% of the world's land surface and are one of the most diverse ecosystems on Earth. They can be found in different parts of the world, including North America, South America, Europe, Asia, and Africa. Grasslands are characterized by grasses and other herbaceous plants, with relatively few trees.

Tropical Grasslands

Tropical grasslands, also known as savannas, are found primarily in Africa, South America, and Australia. They are characterized by a warm, moist climate with seasonal rainfall. Tropical grasslands are home to a wide variety of animals, including large grazers like elephants, giraffes, and zebras.

Temperate Grasslands

Temperate grasslands, also known as prairies, are found primarily in North America and Europe. They are characterized by a moderate climate with a mix of warm and cool seasons. Temperate grasslands host a variety of plant species and grazing animals like bison, antelope, and elk.

Mediterranean-Type Grasslands

Mediterranean-type grasslands are found primarily in Europe, western North America, northwestern Africa, southwestern Asia, and Western Australia. They are characterized by hot, dry summers and mild winters with winter rains. These grasslands are home to plants such as olive trees and herbs, and animals like wild boars, hares, and foxes.

Ocean Habitat

Oceans cover over 70% of the Earth's surface. They are incredibly diverse ecosystems, with different zones supporting various habitats and organisms adapted to their specific conditions. The main oceanic habitats include coastal areas, estuaries, coral reefs, intertidal zones, deep sea environments, and open water.

Coastal Areas

Coastal areas are important transition zones between land and sea. They support a wide range of marine life, including fish, crustaceans, mollusks, and seabirds. Some iconic coastal marine species include starfish, jellyfish, sand dollars, lobsters, and otters.

Estuaries

Estuaries are shallow bodies of water where freshwater from rivers meets saltwater from the sea. They create unique environments with a mix of both saltwater and freshwater habitats, supporting a variety of aquatic life. Examples of estuarine habitats include bayous, swamps, marshes, mudflats, and wetlands[8
