Mountains host a rich mixture of terrestrial and aquatic habitats, which vary across elevations within mountain ranges, and across south-to-north latitudes among mountain ranges. The diversity of habitats is home to a wealth of plants, animals, and other biotas. In relation to those areas, mountains contribute disproportionately to the biodiversity of life on Earth. Mountains occupy about 25% of the earth's land but are home to more than 85% of the world's amphibians, birds, and mammals, many of which are entirely confined to the mountains.
Mountain ecosystems face numerous threats. The most significant include air pollution, climate change, invasive species, altered fire regimes, and habitat fragmentation outside of parks.
Mountainous terrains have certain unifying characteristics. Such terrains have higher elevations than do surrounding areas. Moreover, high relief exists within mountain belts and ranges. Individual mountains, mountain ranges, and mountain belts have been created by different tectonic processes.
According to geologists, any landform which is higher than its surrounding landscape by at least 300 meters can be defined as a mountain. Other characteristics of a mountain include a high point called the peak, steep slopes, and local relief. Mountains are usually found in a series of ranges or chains.
Mountains are formed when tectonic plates collide against each other, causing the land to rise. Some examples of mountain ranges are the Himalayas, Karakoram mountain ranges, Hindu Kush mountains, the Alps, the Andes, etc.
Due to the high altitude and relief, the climate in the mountains is different than what is commonly found in plains. Moreover, the weather can also vary depending on the difference in height, location, exposure to the sun, latitude, etc. The mountains in the temperate region experience more seasons than their counterparts in tropical areas.
However, the climate conditions at the topmost level of mountains usually share the same features. These mountain features include -
Less oxygen density.
Less air pressure.
Lower temperature.
The variation in climate in mountain ecosystems is responsible for some of the richest biodiversity in the world. Very few mountain animals and plants are found at the high altitudes where the weather is extreme.
The few that are found have adapted themselves specifically to survive the climate. Mountain animal adaptations include thick body furs to protect against the cold. Their hooves and legs are specially evolved to help them navigate slippery rocks
Plants on mountains and hills are tall, straight, and have a sloping, much shape to make the snowfall off easily. They usually have no flowers and are conical with seeds. The leaves are needle-shaped with a wax-like coating. For example, small flowerless plants such as cedar, pine, fern, lichen, and moss.
Trees usually have conical shapes.
Leaves are narrow and needle-shaped. It helps them to save water.
Another unique adaptation of plants in hilly areas is that their seeds are attached to the surface of their scales in a cone-like form.
Coniferous trees like pines and spruces are typical examples of such mountain plants.
At the foothills of mountains, where the temperature is moderate, vegetation such as temperate forest, scrubland, tundra is seen. Animals such as black bears, wolves, mountain goats, elk are examples of mountain habitat animals.
Mountain animals include Snow Leopard, Andean Condor, Big Horn Sheep, Chamois, Ibex, Mountain Goat, Mountain Gorilla, Chinchilla, Alpine Marmot, Lynx, Golden Eagle, Vicuna, and Himalayan Tahr. Mountain animals often have special adaptations to life in cold, windy mountain climates.
Given below is a list of some common mountain region animals -
Himalayan Bear –
Bears are one of the most common cold mountain animals. There are two types of bears found in the Himalayan Mountains; these include the Himalayan brown bear (Ursus arctos isabellinus) and the Himalayan black bear (Ursus thibetanus).
The black bears have a glossy black or brownish coat with a whitish mark on their chest. Its long neck and shoulder hairs serve as a mane. The brown bear is sandy or reddish-brown. The Asiatic bear is an omnivore and spends the summer months in mountain forests at 11,800 feet. During winters, these animals descend to lower regions.
Snow Leopards –
They are found in high mountain ranges such as Siberian Mountain and the Himalayas. They have strong legs which help them to jump long distances efficiently. They have thick hair and a long tail which they use as body balance. They are shy animals and are spotted rarely.
Mountain Ibex –
These are wild mountain goats found in north-eastern Africa, Asia, and Europe. They spend the summer in the snowy mountain regions and come down to lower areas in the winter. These mountain animals have grey to brownish fur and males have curved horns and beards. There are several types of Ibex such as Siberian, Asiatic, Nubian, etc.
Marmot –
These giant squirrels can be seen in the mountains of North America and Eurasia. They have thick fur all over the body, short legs, and strong claws to help them dig.
Marmots are vegetarian and feed on tundra vegetation and other mountain region plants. They accumulate food during summer and hibernate during the winters.
Himalayan Red Panda –
They are small mountain animals about the size of a domestic cat. They have reddish-brown fur, a long shaggy tail, and short legs with thick hair. The red pandas mostly feed on bamboos but are also known to eat eggs, birds, and insects and prefer to hunt on their own. These animals are found in the temperate forests of the Himalayas.
The list given above includes only some among the many mountain animals and birds found in the mountain ecosystems around the world. This is all about the ecosystem of mountains. Understand the difference between its flora and fauna with the rest of the ecosystems we find in other topographies. You will get to know the changes and adaptations in their lifestyle due to their diverse habitat when compared to other animals.
1. What is a mountain and what are its main features?
A mountain is a large, natural landform that rises high above the surrounding land. Unlike a hill, it is much taller and steeper. Key features of a mountain include a pointed top called a peak or summit, steep, sloping sides, and a base. They are made of rocks and earth, and the highest mountains are often covered in snow.
2. Why are mountains important for the planet?
Mountains are very important for several reasons. They are a major source of freshwater for rivers and communities. They act as natural barriers, influencing weather patterns and protecting regions from harsh winds. Additionally, mountains are home to a rich biodiversity of unique plants and animals that have adapted to the high-altitude environment.
3. What are some examples of animals found in mountain habitats?
Many animals are specially adapted to live in the mountains. Common examples include:
The Yak, with its long, thick hair for warmth.
The Snow Leopard, with its thick fur and large paws that act like snowshoes.
The Mountain Goat, known for its strong, cloven hooves that help it climb steep, rocky cliffs.
Bighorn Sheep, famous for their large, curved horns.
4. What kind of plants grow in mountain regions and how are they special?
Plants in mountain regions are typically cone-shaped trees like Pines, Firs, and Deodars. They have special adaptations to survive the cold and snowfall. Their sloping shape allows snow to slide off easily, preventing branches from breaking. They also have needle-like leaves with a waxy coating to reduce water loss and protect them from the freezing temperatures.
5. How do animals adapt to survive the extreme cold of the mountains?
Animals have developed several key adaptations to survive the cold mountain climate. These include:
Thick fur or wool: A dense coat of hair or wool traps air and acts as an insulator to keep the animal warm (e.g., yaks, snow leopards).
Layers of fat: An extra layer of body fat provides insulation and an energy reserve.
Hibernation: Some animals, like bears, hibernate during the harshest winter months to conserve energy.
Strong hooves: Animals like the ibex and mountain goat have strong hooves to get a firm grip on rocky and icy surfaces.
6. How is the weather in the mountains different from that in the plains?
The weather in the mountains is significantly different from the plains. As altitude increases, the temperature decreases, making it much colder. The air is also thinner, with less oxygen. Mountain weather is highly unpredictable and can change rapidly, shifting from clear and sunny to stormy and cold in a very short time. They also receive much more snowfall compared to the plains.
7. Can animals live at the very top of the highest mountains? Why or why not?
No, animals generally cannot live at the absolute summit of the world's highest mountains, like Mount Everest. This is because the conditions are too extreme. The primary reasons are a severe lack of oxygen, incredibly low temperatures, very little to no food sources, and exposure to powerful, freezing winds. While some birds may fly over these peaks and hardy animals like yaks live at very high altitudes, they do not inhabit the highest points.
8. What is the main difference between a mountain goat and a mountain sheep?
While both are adapted to mountain life, there are clear differences. A mountain goat typically has a beard and its horns are slender, growing straight up before curving backwards. They are exceptional climbers, often found on near-vertical cliffs. In contrast, a mountain sheep (like a Bighorn) does not have a beard, and its most distinct feature is its thick, heavy horns that curl around the sides of its head.
