What is hotspot area in biodiversity?

To be classified as a biodiversity hotspot, a region must have lost at least 70 percent of its original natural vegetation, usually due to human activity. There are over 30 recognized biodiversity hotspots in the world. The Andes Mountains Tropical Hotspot is the world’s most diverse hotspot.

What are hotspot areas?

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. …
  • It must have 30% or less of its original natural vegetation.

Where is biodiversity hotspots?

The California Coast

This hotspot stretches from the northern point of Baja California, up the entire California coast, and gets wider as it moves north, including a bit of southeast Oregon. Beloved tree species include the giant sequoia and the redwood.

Why is it called biodiversity hotspots?

Biodiversity Is Unevenly Distributed Around the Globe. With the enormous number of species that exists on Earth, it is remarkable that the distribution of these species is so highly concentrated in specific areas. … These areas that are particularly important for biodiversity conservation are called biodiversity hotspots …

What are hotspots of biodiversity class 12?

Class 12 Biology: A biodiversity hotspot is a biogeographic region that has a significant pool of biodiversity but at the same time it is also threatened with destruction. The British biologist Norman Myers gave the term “biodiversity hotspot” in 1988.

What is biodiversity hotspot in India?

India hosts 4 biodiversity hotspots: the Himalayas, the Western Ghats, the Indo-Burma region and the Sundaland (Includes Nicobar group of Islands). These hotspots have numerous endemic species.

Where are hotspots located?

Most of these are located under plate interiors (for example, the African Plate), but some occur near diverging plate boundaries. Some are concentrated near the mid-oceanic ridge system, such as beneath Iceland, the Azores, and the Galapagos Islands. A few hotspots are thought to exist below the North American Plate.

Which is the hotspot region?

Biodiversity hotspots are the regions which possess high levels of species richness, high degree of endemism and no loss to habitats.

What are examples of hotspots?

Examples include the Hawaii, Iceland and Yellowstone hotspots. A hotspot’s position on the Earth’s surface is independent of tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them.

What is biodiversity hotspot Class 10?
