Biodiversity Hotspots

Eight Hottest Hotspots

There are 36 biodiversity hotspots across the planet, each home to a spectacular variety of unique flora and fauna found nowhere else on Earth. However, among them, eight regions stand out as the “hottest hotspots” — areas that possess exceptional levels of endemism and face the most severe threats to their biodiversity, making them even more critical for global conservation efforts.

• Indo – Burma region
  • The Indo-Burma Region spans parts of northeastern India, Myanmar, Thailand, Laos, Cambodia, Vietnam, and southern China, making it one of the most biologically diverse areas on Earth. 
  • It encompasses a variety of ecosystems, including tropical and subtropical forests, wetlands, rivers, and mangroves, supporting exceptional species richness and endemism. 
  • The region is home to rare and iconic species such as the Saola (Asian unicorn), the giant ibis, and several endangered freshwater turtles. However, due to habitat loss, deforestation, and human encroachment, Indo-Burma remains one of the most threatened biodiversity hotspots in the world.
• Sundaland
  • Sundaland is a biogeographical region in Southeast Asia encompassing the Malay Peninsula, Borneo, Sumatra, Java, and nearby islands. 
  • It is one of the world’s most important biodiversity hotspots, characterized by ancient tropical rainforests that rank among the oldest and most species-rich ecosystems on Earth. 
  • The region supports extraordinary wildlife diversity, including several critically endangered species such as the orangutan, Sumatran tiger, and Bornean pygmy elephant, highlighting its global ecological significance.
• Philippines
  • The country hosts over 52,000 species of plants and animals, more than half of which are found nowhere else on Earth. Its diverse ecosystems — including rainforests, coral reefs, and mangroves — support iconic and endangered species such as the Philippine eagle and the tarsier, making it a vital hotspot for global conservation.
• Western Ghats & Srilanka
  • The Western Ghats in India, along with Sri Lanka, form a biodiversity hotspot of global significance.
  • The Western Ghats, a UNESCO World Heritage Site, harbor numerous endemic species such as the lion-tailed macaque, the Nilgiri tahr, and a rich diversity of amphibians and plant life. Sri Lanka, with its varied ecosystems ranging from tropical rainforests to dry lowlands, supports unique species like the Sri Lankan leopard and the purple-faced langur
• Madagascar:
  • Madagascar, an island nation located off the southeastern coast of Africa, is one of the world’s richest biodiversity hotspots.
  • Over 90% of its wildlife is endemic, meaning it exists nowhere else on the planet.
  • The island hosts an extraordinary range of ecosystems — from lush rainforests to dry spiny forests — and shelters unique species such as lemurs, chameleons, and the majestic baobab trees.
• Eastern arc & coastal forests of Tanzania/Kenya
  • The Eastern Arc Mountains and Coastal Forests of Tanzania and Kenya are among the oldest and most biologically rich ecosystems on Earth. 
  • This region is defined by isolated mountain ranges, ancient rainforests, and diverse coastal habitats, which have evolved over millions of years, fostering exceptional endemism. 
  • It is home to unique species such as the Usambara eagle-owl, the Tanzanian black-and-white colobus, and a remarkable variety of endemic plant species.
• Caribbean island
  • The Caribbean Islands form a major biodiversity hotspot consisting of over 7,000 islands, islets, reefs, and cays. 
  • This region hosts an extraordinary range of ecosystems — from tropical rainforests and coral reefs to mangrove swamps — that support remarkable biological diversity. 
  • The Caribbean is home to a high number of endemic species, including many unique birds, amphibians, and reptiles, making it one of the most ecologically distinctive and fragile regions on Earth.
• Brazil’s Atlantic forests
  • The Atlantic Forest of Brazil once stretched extensively along the country’s Atlantic coast but today survives at only about 12% of its original extent, largely due to urbanization, agriculture, and deforestation. 
  • Despite this drastic loss, it remains one of the planet’s most vital biodiversity hotspots, harboring thousands of endemic species, including the golden lion tamarin, the maned three-toed sloth, and an incredible variety of plant life. 
  • The Atlantic Forest’s unique climate and geography have fostered a diverse range of habitats, from mangroves to cloud forests, making it one of the most important ecosystems in the world.
