How many biodiversity hotspots are there in India in 2021?

Biodiversity Hotspots in India are four in number. Across the world, 36 areas qualify as Biodiversity hotspots.

Which of the following is hotspot of biodiversity in India?

In India four hotspots are present namely, Himalayas, Western Ghats, Indo-Burman region and Sundaland which consists of Nicobar group of Islands. So, the correct answer is option “C” that is the Western Ghats are considered a hot-spot of biodiversity in India.

Which state has highest biodiversity in India?

Sundaland. This region lies in South-East Asia and includes Thailand, Singapore, Indonesia, Brunei, and Malaysia. The Nicobar Islands represent India. These islands were declared as the world biosphere reserve in 2013 by the United Nations.

Which is the hotspot region?

To qualify as a biodiversity hotspot, a region must meet two strict criteria: It must have at least 1,500 vascular plants as endemics — which is to say, it must have a high percentage of plant life found nowhere else on the planet. A hotspot, in other words, is irreplaceable. In other words, it must be threatened.

What is biodiversity hotspot example?

Biodiversity hotspots are regions that are both biologically fertile (rich distribution of plants and animals) and highly threatened. Examples of biodiversity hotspots are forest habitats as they constantly face destruction and degradation due to illegal logging, pollution and deforestation.

Which one is hotspot of biodiversity?

They are western ghats and Sri Lanka, Indo-Burma, and Eastern Himalayas. Note that even the biodiversity hotspots cover less than two percent of the world’s total land area, by protecting these regions we can decrease the rate of species extinctions by 30%.

What are the two types of biodiversity?

Types of Biodiversity. Biodiversity includes three main types: diversity within species (genetic diversity), between species (species diversity) and between ecosystems (ecosystem diversity).

How many hotspots are in India?

four biodiversity hotspots
India has four biodiversity hotspots, i.e., Eastern Himalayas, Western Himalayas, Western Ghats and Andaman and Nicobar Islands.

Why India is called mega biodiversity hotspot?

An area is known as a hotspot if it contains at least 0.5 per cent of endemic plant species. India is considered a mega-diversity hotspot due to the great diversity of organisms found here, ranging from eastern to western ghats to northern and southern India as well. Mainly Western ghats are now at high risk.

How does an area qualify as a biodiversity hotspot?

To qualify as a biodiversity hotspot, an area must meet two strict criteria: Contain at least 1,500 species of vascular plants found nowhere else on Earth (known as “endemic” species). Have lost at least 70 percent of its primary native vegetation. Many of the biodiversity hotspots exceed the two criteria.

Where are critical biodiversity hotspots located?

The Atlantic Forest in South America is another example of a biodiversity hotspot. The forest is located along the Atlantic coasts of Brazil, Paraguay, and Argentina.

Why is the importance of biodiversity hotspots?

Biodiversity importance – The biodiversity importance of hotspots is due to the high vulnerability of habitats and high irreplaceability of species found within large geographic regions . This means that these areas and the species present within them are both under high levels of threat and of significant global value based on their uniqueness.

What are the criteria for a ‘biodiversity hotspot’?

The criteria for a biodiversity hotspot includes: High biodiversity High endemism ; and Massive threat to flora and fauna
