Terai–Duar Savanna And Grasslands
The Terai–Duar savanna and grasslands is a narrow lowland ecoregion at the base of the Himalayas, about wide, and a continuation of the Indo-Gangetic Plain in India, Nepal and Bhutan. It is colloquially called ''Terai'' in the Ganges Basin east to Nepal, then ''Dooars'' in West Bengal, Bhutan and Assam east to the Brahmaputra River. It harbours the world's tallest grasslands, which are the most threatened and rare worldwide.Dinerstein, E., Loucks, C. (2001). Location and description This tropical and subtropical grasslands, savannas, and shrublands biome stretches from western Bhutan to southern Nepal's Terai, westward to Banke, covering the Dang and Deukhuri Valleys along the Rapti River to India's Bhabar and Doon Valley. Each end crosses the border into India's states of Uttarakhand, Uttar Pradesh and Bihar. The eastern and central areas are wetter than the western end. In Nepal, the wetlands of Koshi Tappu Wildlife Reserve, Beeshazar Tal in the bufferzone of Chitwan ...

Indian Rhinoceros
} The Indian rhinoceros (''Rhinoceros unicornis''), also called the Indian rhino, greater one-horned rhinoceros or great Indian rhinoceros, is a rhinoceros species native to the Indian subcontinent. It is listed as Vulnerable on the IUCN Red List, as populations are fragmented and restricted to less than . Moreover, the extent and quality of the rhino's most important habitat, the alluvial Terai-Duar savanna and grasslands and riverine forest, is considered to be in decline due to human and livestock encroachment. As of August 2018, the global population was estimated to comprise 3,588 individuals, including 2,939 individuals in India and 649 in Nepal. Kaziranga National Park alone had an estimated population of 2,048 rhinos in 2009. Pobitora Wildlife Sanctuary in Assam has the highest density of Indian rhinos in the world with 84 individuals in an area of in 2009. Indian rhinos once ranged throughout the entire stretch of the Indo-Gangetic Plain, but excessive hunting and agri ...

Bhabar
Bhabar or Bhabhar ( Kumaoni: bhābar) is a region south of the Lower Himalayas and the Sivalik Hills in Kumaon, India, containing some of the largest cities of Kumaon, Haldwani and Ramnagar, both in Nainital District. It is the alluvial apron of sediments washed down from the Sivaliks along the northern edge of the Indo-Gangetic Plain. Etymology The name ''Bhabar'' refers to a local tall-growing grass, '' Eulaliopsis binata'', used for the manufacture of paper and rope. Overview Bhabar plains are located in Kumaon. Bhabar is the gently-sloping coarse alluvial zone below the Sivalik Hills (outermost foothills of the Himalayas) where streams disappear into permeable sediments. The underground water level is deep in this region, then rises to the surface in the Terai below where coarse alluvium gives way to less permeable silt and clay. The Ganges River lies to the west and Sharda to the east. Being at the junction of Himalayas and the Indo-Gangetic Plain, Bhabar contains almos ...

West Rapti, also known as the Kuwano drains Rapti Zone in Mid-Western Region, Nepal, then Awadh and Purvanchal regions of Uttar Pradesh state, India before joining the Ghaghara—a major left bank tributary of the Ganges known as the Karnali inside Nepal. The West Rapti is notable for ''janajati'' ethnic groups – Kham Magar among its highland sources and then Tharu in Inner Terai Deukhuri Valley, for its irrigation and hydroelectric potential, and for recurrent floods that led to its nickname "Gorakhpur's Sorrow". History As ancient Airavati river Aciravati, Achirvati or Airavati is the ancient name for a river has been identified with the modern Rapti, flowing through what is now Nepal and the northern portion of Uttar Pradesh. The Chinese pilgrim Xuanzang knew it as A-chi-lo. Jain texts mention it as Eravai. The ancient city of Sravasti, once capital of Kosala Kingdom, stood on the western bank of the Achirvati.

Inner Terai Valleys Of Nepal
The Inner Terai Valleys of Nepal comprise several elongated river valleys in the southern lowland Terai part of the country. These tropical valleys are enclosed by the Himalayan foothills, viz the Mahabharat Range and the Sivalik Hills farther south. These valleys are part of the Terai-Duar savanna and grasslands ecoregion.Dinerstein, E., Loucks, C. (2001). They are filled up with coarse to fine alluvial sediments. The Chitwan Valley and the Dang and Deukhuri Valleys are some of the largest Inner Terai Valleys. Malaria was prevalent in this region until the late 1950s. Since its eradication, the area became a viable destination for large-scale migration of people from the hills who transformed the area from virgin forest and grassland to farmland. Geology The Inner Terai valleys lie between the Sivalik Hills and Mahabharat Range. They hold flat plains with winding rivers that shift their courses from time to time, running northwest or southeast along the axis of the Sival ...

Biome
A biome () is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate. Biomes may span more than one continent. Biome is a broader term than habitat and can comprise a variety of habitats. While a biome can cover large areas, a microbiome is a mix of organisms that coexist in a defined space on a much smaller scale. For example, the human microbiome is the collection of bacteria, viruses, and other microorganisms that are present on or in a human body. A biota is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. Etymology The term was suggested in 1916 by Clements, originally as a synonym for ''biotic community'' of Möbius (1877). Later, it gained its c ...

Grassland
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush ( Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * " ...
