Biodiversity hotspot in the context of Endemism

Madagascar, officially the Republic of Madagascar, is an island country in the Indian Ocean that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's fourth-largest island, the second-largest island country, and the 46th-largest country overall. Its capital and largest city is Antananarivo.

Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife being endemic. The island has a subtropical to tropical maritime climate. Madagascar was first permanently settled during or before the mid-first millennium CE (roughly 500 to 700) by Austronesian peoples, presumably arriving on outrigger canoes from present-day Indonesia. These were joined around the ninth century by Bantu groups crossing the Mozambique Channel from East Africa. Other groups continued to settle on Madagascar over time, each one making lasting contributions to Malagasy cultural life. Consequently, there are 18 or more classified peoples of Madagascar, the most numerous being the Merina of the central highlands.

Conservation International (CI) is an American nonprofit environmental organization headquartered in Crystal City, Virginia.

As of 2025, CI's stated mission is "to spotlight and secure the critical benefits that nature provides to humanity," through protecting biodiversity hotspots, partnering with the communities that rely on them economically, engaging in field research and supporting environmentally-friendly policies. The organization employs 1,700 people and works with more than 2,000 partners in 29 countries. CI has helped support 1,200 protected areas and interventions across 77 countries, protecting more than 13 million square kilometers (5 million square miles) of land and sea. CI was founded in 1987 by Spencer Beebe and Peter Seligmann.

The Western Himalayas are the western half of the Himalayas, in northwestern India and northern Pakistan. Four of the five tributaries of the Indus River in Punjab (Beas, Chenab, Jhelum, and Ravi) rise in the Western Himalayas; while the fifth, the Sutlej cuts through the range after rising in Tibet.

Included within the Western Himalayas are the Zanskar Range, the Pir Panjal Range, and the Dhauladhar Range, and western parts of the Sivalik Range and the Great Himalayas. The highest point is Nanga Parbat (26,660 feet or 8,126 metres), at the northwestern end of the region. It is part of the Himalayan biodiversity hotspot.

The Eastern Himalayas extend from eastern Nepal across Northeast India, Bhutan, the Tibet Autonomous Region to Yunnan in China and northern Myanmar. The climate of this region is influenced by the monsoon of South Asia from June to September. It is a biodiversity hotspot, with notable biocultural diversity.

The Margalla Hills is a hill range of subtropical moist broadleaf forest ecoregion in the Indomalayan realm within the Margalla Hills National Park in the northwestern Punjab region in Pakistan, forming the northern edge of the Islamabad Capital Territory, just south of Haripur District, Khyber Pakhtunkhwa. They are part of the Himalayan foothills on the Himalayan biodiversity hotspot. The Margalla range has an area of 12,605 hectares. It is a range with many valleys and rainforests as well as high mountains.

A grove is a small group of trees with minimal or no undergrowth, or a small orchard planted for the cultivation of fruits or nuts. Naturally occurring groves are typically small, perhaps a few acres at most, such as a sequoia grove. In contrast, orchards, which are normally intentional planting of trees, may be small or very large, like the apple orchards in Washington state, orange groves in Florida and olive groves in Australia.

A grove may be called an 'arbour' or 'arbor', which is not to be confused with the garden structure pergola, which also sometimes goes under that name. Other words for groups of trees include woodland, woodlot, thicket, and stand. Groves often contain plant and animal species that have become extinct in adjacent areas, and they harbor great genetic diversity. Therefore, they have become biodiversity hotspots, as various species seek refuge in the areas due to progressive habitat destruction.

The main diversity among genus Araucaria is hosted in New Caledonia, where 14 species, all endemic, are described out of a total of 20 extant species. These New Caledonian species are mainly found as dispersed populations in open areas, where competition is less intense.

New Caledonia, considered as the smallest of the most significant biodiversity hotspots in the world, hosts a unique flora of which 75.1% is endemic. Species of Araucaria trees can be found in every habitat that New Caledonia possesses. However, almost all of them are growing on ultramafic substrate, characterized by low fertility (low N, P, K levels) and high levels of heavy metals (nickel, cobalt, etc.).

The Pilbara (/ˈpɪlbərə/) is a large, dry, sparsely populated region in the north of Western Australia. It is known for its Aboriginal people, its geography, its red earth, and its vast mineral deposits, in particular iron ore. It is also a global biodiversity hotspot for subterranean fauna.

Kaziranga National Park is a national park in the Golaghat, Sonitpur, Biswanath and Nagaon districts of the state of Assam, India. KNP has 5 ranges. The park, which hosts two-thirds of the world's Indian rhinoceroses, is a UNESCO World Heritage Site. According to a March 2018 census conducted jointly by the Forest Department of the Government of Assam and some recognized wildlife NGOs, the rhino population in Kaziranga National Park is 2,613. It comprises 1,641 adult rhinos and 385 calves.

Kaziranga National Park was declared a Tiger Reserve in 2006. The park is home to large breeding populations of elephants, wild water buffalo, and swamp deer. Kaziranga is recognized as an Important Bird Area by BirdLife International for conservation of avifaunal species which refers as the birds or types of birds found in a specific region, period, or environment. When compared with other protected areas in India, Kaziranga has achieved notable success in wildlife conservation. Located on the edge of the Eastern Himalaya biodiversity hotspot, the park combines high species diversity and visibility.

Komodo National Park (Indonesian: Taman Nasional Komodo) is a national park in Indonesia located within the Lesser Sunda Islands in the border region between the provinces of East Nusa Tenggara and West Nusa Tenggara. The park includes the three larger islands Komodo, Padar and Rinca, and 26 smaller ones, with a total area of 1,733 km (669 sq mi), with 603 km (233 sq mi) of it land. The national park was founded in 1980 to protect the Komodo dragon, the world's largest lizard. Later it was dedicated to protecting other species, including marine species. In 1991 the national park was declared a UNESCO World Heritage Site and a Man and Biosphere Reserve. It is considered one of the world's 25 biodiversity hotspots.

Komodo National Park has been selected as one of the New 7 Wonders of Nature. The waters surrounding Komodo island contain rich marine biodiversity. Komodo islands is also a part of the Coral Triangle, which contains some of the richest marine biodiversity on Earth.

Indo-Burma is a biodiversity hotspot designated by Conservation International.
