Biodiversity hotspots are regions of the world that contain a high level of biodiversity but are also threatened by human activities.
These hotspots are often located in tropical or subtropical climates, and generally have high levels of endemism, meaning that many of the species found there are not found anywhere else in the world.
Hotspots are home to a large number of species, and many of these species are endangered or threatened. Conservation efforts are focused on these areas in order to protect and preserve the unique biodiversity they contain.
Biodiversity hotspot’s main qualifying criteria
In order for an area to be declared a Biodiversity Hotspot, it must meet four criteria. These criteria include:
- Significant levels of biodiversity and endemism;
- A significant threat of habitat destruction;
- A significant loss of habitat; and
- A large human population is dependent on the area for resources.
- The area must be both globally and nationally significant: This means that the area is important not only to the local ecosystem but also to the global ecosystem. It also means that the area is of significance to the local government or community.
- The area has to have lost at least 70% of its original habitat: Habitat loss refers to the destruction of natural environments, such as forests, wetlands, and grasslands, that are essential for the survival of certain species.
- The area must contain at least 1500 species of vascular plants as endemics: Vascular plants are those that have specialized tissue for conducting water and nutrients throughout the plant. Endemic species are those that are native to a particular area and are not found anywhere else in the world.
Following the criteria there are four major biodiversity hotspots in India:
- The Himalayas
- The Western Ghats
- The Eastern Himalayas
- The Nicobar Islands.
Biodiversity Hotspots in India
Biodiversity Hotspots in India are areas with a high diversity of species, many of which are endemic (unique) to the region. They are defined by the World Wildlife Fund (WWF) as regions that contain at least 1,500 species of vascular plants (> 0.5% of the world’s total) as endemics and have lost 70% of their original habitat.
India has five such hotspots located in the Eastern Himalayas, the Western Ghats, the Indo-Burma region, the Nicobar Islands, and the Sundarbans. These hotspots are home to some of India’s most iconic species, including tigers, leopards, Indian elephants, and the great Indian one-horned rhinoceros.
They also contain an array of rare and threatened species, such as the Western Ghats and Nicobar Islands’ endemic species of frogs, toads, and geckos. Conservation efforts are needed to protect these hotspots from the threats posed by deforestation, over-exploitation of resources, and climate change.

- Species Biodiversity: This is the most basic level of biodiversity, referring to the variety of species within a particular habitat or region. This level of biodiversity is important for the health of ecosystems, as different species interact and depend on each other for survival.
- Genetic Biodiversity: This level of biodiversity refers to the variety of genetic material within a species, which can be found in different individuals of the same species. Genetic diversity is important for species to adapt to changing environments and helps ensure the long-term survival of the species.
- Ecosystem Biodiversity: This level of biodiversity refers to the variety of habitats and ecological processes within an area. This includes the diversity of landscapes, habitats, and species interactions. This level of biodiversity is important for the stability of ecosystems and their ability to cope with environmental changes.
