Biodiversity Hotspots in India – Everything you need to know

Biodiversity refers to a variety of plants, animals, organisms, amphibians, coral reefs and another biological form of life or vegetation in a particular region or a specific part of the earth. There are 4 Biodiversity Hotspots in India, here is the complete details about Biodiversity Hotspots.

What is Biodiversity Hotspot?

A Hotspot in general language is an area/place/ region with high activity of a particular thing/species/ event. Therefore, A biodiversity hotspot in India is a region that is an active reservoir of endemic plants, animals, organisms, etc, whose vegetation is in danger or threatened and needs to be conserved for the betterment of the ecosystem and environment.

A region to get the status of a biodiversity hotspot has to have the following two criteria

  • Endemism – At Least 1,500 species of its vascular plants must not be found anywhere else on the Earth. Such unique species of plants are known as endemic plants or native to that particular region or place. These plants are almost impossible to replace if lost completely.
  • Habitat Loss – If around 70% of the native plantation of the region is lost, then it is deemed to be a Biodiversity Hotspot.

Biodiversity hotspots in the world

Norman Myers, a biologist, in the year 1988 has come up with the term Biodiversity Hotspot as a biological region with a threat to endemic plants and ‘loss of habitat’.

There are 36 Biodiversity hotspots in the world that covers around 2.4% of the earth’s surface which hosts more than 50% of world endemic plants and more than 40% of endemic species of birds, mammals, and amphibians.

The North American Coastal Plains is the latest addition to the list of Biodiversity Hotspot of the world to become the 36th Biodiversity Hotspot.

Why biodiversity hotspots are important?

Every minute organism and plant or a big mammal or tree plays an important role in the ecosystem. These biodiversity hotspots are the home to thousands of such endemic organisms, plants, and vegetation. Thus, have a huge impact on the ecosystem and biosphere. All these hotspots of the world are the life support system for the earth’s environment, ecosystem, and human beings.

These hotspots are helpful in many ways like protecting natural resources like pure water, soil, maintenance of the ecosystem, controlling pollution and recycling the nutrients of the ecosystem. 

Biodiversity hotspots are also a good source of many of the medicinal resources, pharmaceutical drugs, and wood products. Hotspots are also a great place for research and education-related activities for the betterment of the human race.

Also, there are around 2 billion people who live in these 36 biodiversity hotspots of the world. They live and work here for their living. Most of these tribes are native to these hotspots. Many of these biodiversities have a higher density of human beings than that of the other part of the world, And their relation with these hotspots are far more strong than we think.
