- The Caribbean Islands.
- The Atlantic Forest in Brazil.
- Southeast Asia.
- The Philippines.
- The Horn of Africa.

What is biodiversity hotspot?
A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction. The term biodiversity hotspot specifically refers to 25 biologically rich areas around the world that have lost at least 70 percent of their original habitat.
What is biodiversity hotspot give example?
A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened with destruction. For example forests are considered as biodiversity hotspots.
Why Sikkim is called biodiversity hotspot?
Sikkim is considered as the biodiversity hotspot because there are 5500 flowering plants in Sikkim species only found within this 7096 kilometre square geographical area (Hajra and Verma 1996…….. common medicinal plants of Darjeeling and Sikkim in Himalaya.
What is considered a hotspot?
Looking at the period from June 14 to June 28, 31 states are classified as hotspots (i.e., have increasing cases, and increasing positivity rates over the most recent 14-day period or a positivity rate of 10% or greater).
Why is Sikkim rich in biodiversity?
Most of the high altitude medicinal plants are rare and endangered species. Sikkim also has 28 Mountains/Peaks, more than 80 Glaciers, 227 high altitude lakes/wetlands and over 104 rivers and streams. Many species of Himalayan origin have revolutionized the allopathic systems of medicine.
What is Sikkim diversity?
Covering just 0.22% of the geographical area of India, Sikkim shows great biological diversity. The vast altitudinal variation of elevations from around 300 m to 8598 m within very short distances is responsible for the varied ecoregions of the State.
What makes a biogeographic region a biodiversity hotspot?
Biodiversity Hotspots are biogeographic regions that have the richest and the most threatened reservoirs of plant and animal life on earth. These regions have been identified as some of the world’s most important ecosystems that are home to a high number of endemic species that also provide crucial ecosystem services for the benefit of humans.
Who is the author of the biodiversity hotspot?
Norman Myers wrote about the concept in two articles in “The Environmentalist” (1988), and 1990 revised after thorough analysis by Myers and others “Hotspots: Earth’s Biologically Richest and Most Endangered Terrestrial Ecoregions” and a paper published in the journal Nature.
Is there any way to conserve biodiversity hotspots?
Hotspot conservation initiatives. Only a small percentage of the total land area within biodiversity hotspots is now protected. Several international organizations are working in many ways to conserve biodiversity hotspots.
Why are ecological hotspots so important to humans?
These ecological hotspots are most critical to human survival and sadly, these are the ones most threatened. Hotspots are among the richest and most important ecosystems on the planet. They are home to numerous vulnerable species whose survival is directly dependent on our actions.
