Indomalayan realm in the context of "Margalla Hills"

The Australasian realm is one of eight biogeographic realms that is coincident with, but not (by some definitions) the same as, the geographical region of Australasia. The realm includes Australia, the island of New Guinea (comprising Papua New Guinea and the Indonesian province of Papua), and the eastern part of the Indonesian archipelago, including the island of Sulawesi, the Moluccas (the Indonesian provinces of Maluku and North Maluku), and the islands of Lombok, Sumbawa, Sumba, Flores, and Timor, often known as the Lesser Sundas.

The Australasian realm also includes several Pacific island groups, including the Bismarck Archipelago, Vanuatu, the Solomon Islands, and New Caledonia. New Zealand and its surrounding islands are a distinctive sub-region of the Australasian realm. The rest of Indonesia is part of the Indomalayan realm. In the classification scheme developed by Miklos Udvardy, New Guinea, New Caledonia, Solomon Islands and New Zealand are placed in the Oceanian realm.

A biogeographic realm is the broadest biogeographic division of Earth's land surface, based on distributional patterns of terrestrial organisms. They are subdivided into bioregions, which are further subdivided into ecoregions.A biogeographic realm is also known as "ecozone", although that term may also refer to ecoregions.

India is the world's 8th most biodiverse region with a 0.46 BioD score on diversity index, 102,718 species of fauna and 23.39% of the nation's geographical area under forest and tree cover in 2020. India encompasses a wide range of biomes: desert, high mountains, highlands, tropical and temperate forests, swamplands, plains, grasslands, areas surrounding rivers, as well as island archipelago. Officially, four out of the 36 Biodiversity Hotspots in the world are present in India: the Himalayas, the Western Ghats, the Indo-Burma and the Nicobar Islands. To these may be added the Sundarbans and the Terrai-Duar Savannah grasslands for their unique foliage and animal species.These hotspots have numerous endemic species. Nearly 5% of India's total area is formally classified under protected areas .

India, for the most part, lies within the Indomalayan realm, with the upper reaches of the Himalayas forming part of the Palearctic realm; the contours of 2000 to 2500m are considered to be the altitudinal boundary between the Indo-Malayan and Palearctic zones. India displays significant biodiversity. One of seventeen megadiverse countries, it is home to 7.6% of all mammalian, 12.6% of all avian, 6.2% of all reptilian, 4.4% of all amphibian and 11.7% of all fish.

As of 2023, Pakistan has 37 national parks (Urdu: پاکستان کے نیشنل پارک) that are recognised by World Database on Protected Areas. In 2012, 25 of these were under supervision of respective provincial governments and remaining were in private care. Only some of these are under the conservation scope of International Union for Conservation of Nature (IUCN). Protection and conservation of the environment of Pakistan was included in the concurrent constitution of 1973. As a result, Environment Protection Ordinance was enacted in 1983, which was mainly regulated by the Environment and Urban Affairs Division. Later, a new system of 'Modern Protected Areas' legislation began at the provincial level which assigned the protected areas with designations such as national parks, wildlife sanctuaries and game reserves. Further recommendations of the national parks of the Indomalayan realm were highlighted in the IUCN review of 1986. Nevertheless, the development of national parks was mainly carried out by National Conservation Strategy of 1992. Due to more awareness about their importance in conservation of biodiversity, 10 national parks have been established during the time period from 1993 to 2005.

According to the 'Modern Protected Areas' legislation, a national park is a protected area set aside by the government for the protection and conservation of its outstanding scenery and wildlife in a natural state. It is accessible to public for research, education and recreation. In order to promote public use, construction of roads and rest houses is permitted. Use of firearms, polluting water, cleaning of land for cultivation, destruction of wildlife is banned in these areas.

The frogmouths (Podargidae) are a group of nocturnal birds related to owlet-nightjars, swifts, and hummingbirds. Species in the group are distributed in the Indomalayan and Australasian realms.

This page features a list of biogeographic provinces that were developed by Miklos Udvardy in 1975, later modified by other authors. Biogeographic Province is a biotic subdivision of biogeographic realms subdivided into ecoregions, which are classified based on their biomes or habitat types and, on this page, correspond to the floristic kingdoms of botany.

The provinces represent the large areas of Earth's surface within which organisms have been evolving in relative isolation over long periods of time, separated from one another by geographic features, such as oceans, broad deserts, or high mountain ranges, that constitute barriers to migration.

The Thal desert (Punjabi: تَھل صحرا, romanized: Thal Sahrā'h; Urdu: صحرائے تھل, romanized: Sehrā-é-Thal) is situated at 31°10' N and 71°30' E in the province of Punjab, Pakistan. Located near the Pothohar Plateau, the area falls under the Indomalayan biogeographic realm and stretches for a length of approximately 190 miles (310 km) with a maximum breadth of 70 miles (119 km). It is bound by the piedmont of the northern Salt Range, the Indus River floodplains in the west and the Jhelum and Chenab rivers' floodplains in the east. It is a subtropical sandy desert that resembles the deserts of Cholistan and Thar geographically.

The region is characterized by sand dunes, prone to massive shifting and rolling, as well as scant rainfall, high diurnal variation of temperature and high wind velocity. Aridity is a common feature and perennial grasses make up much of the vegetation. Agriculture and livestock rearing form the main sources of livelihood for the population, who live in small scattered settlements throughout the desert.
