Ecology Of The Himalayas
The ecology of the Himalayas varies with climate, rainfall, altitude, and soils. The climate ranges from tropical at the base of the mountains to permanent ice and snow at the highest elevations. The amount of yearly rainfall increases from west to east along the southern front of the range. This diversity of climate, altitude, rainfall and soil conditions supports a variety of distinct plant and animal species, such as the Nepal gray langur (''Semnopithecus schistaceus'') Lowland forests On the Indo-Gangetic plain at the base of the mountains, an alluvial plain drained by the Indus and Ganges-Brahmaputra river systems, vegetation varies from west to east with rainfall. The xeric Northwestern thorn scrub forests occupy the plains of Pakistani and the Indian Punjab. Further east lie the Upper Gangetic Plains moist deciduous forests of Uttarakhand and Uttar Pradesh and the Lower Gangetic Plains moist deciduous forests of Bihar and West Bengal. These are monsoon forests, with drought-d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nepal Gray Langur
The Nepal gray langur (''Semnopithecus schistaceus'') is a gray langur endemic to the Himalayas in Nepal, far southwestern Tibet, northern India, northern Pakistan, Bhutan and possibly Afghanistan. It is found in forests at an elevation of . Its easternmost limit in India is Buxa Tiger Reserve in northern West Bengal, at least up to the Rydak river. The Nepal gray langur is both terrestrial and arboreal and eats leaves. At , the heaviest langur ever recorded was a male Nepal gray langur.

Rhinoceros Unicornis Chitwan National Park Nepal 2005 2
A rhinoceros (; ; ), commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates in the family Rhinocerotidae. (It can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea.) Two of the extant species are native to Africa, and three to South and Southeast Asia. Rhinoceroses are some of the largest remaining megafauna: all weigh at least one tonne in adulthood. They have a herbivore, herbivorous diet, small brains (400–600 g) for mammals of their size, one or two horns, and a thick (1.5–5 cm), protective skin formed from layers of collagen positioned in a crystal structure, lattice structure. They generally eat leafy material, although their ability to ferment food in their colon (anatomy), hindgut allows them to subsist on more fibrous plant matter when necessary. Unlike other perissodactyls, the two African species of rhinoceros lack teeth at the front of their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sivalik Hills
The Sivalik Hills, also known as the Shivalik Hills and Churia Hills, are a mountain range of the outer Himalayas that stretches over about from the Indus River eastwards close to the Brahmaputra River, spanning the northern parts of the Indian subcontinent. It is wide with an average elevation of . Between the Teesta and Raidāk Rivers in Assam is a gap of about . "Sivalik" literally means 'tresses of Shiva'. Sivalik region is home to the Soanian archaeological culture. Geology Geologically, the Sivalik Hills belong to the Tertiary deposits of the outer Himalayas. They are chiefly composed of sandstone and conglomerate rock formations, which are the solidified detritus of the Himalayas to their north; they are poorly consolidated. The remnant magnetisation of siltstones and sandstones indicates that they were deposited 16–5.2 million years ago. In Nepal, the Karnali River exposes the oldest part of the Shivalik Hills. They are bounded on the south by a fault syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sal Tree
''Shorea robusta'', the sal tree, sāla, shala, sakhua, or sarai, is a species of tree in the family Dipterocarpaceae. The tree is native to India, Bangladesh, Nepal, Tibet and across the Himalayan regions . Evolution Fossil evidence from lignite mines in the Indian states of Rajasthan and Gujarat indicate that sal trees (or at least a closely related ''Shorea'' species) have been a dominant tree species of forests of the Indian subcontinent since at least the early Eocene (roughly 49 million years ago), at a time when the region otherwise supported a very different biota from the modern day. Evidence comes from the numerous amber nodules in these rocks, which originate from the dammar resin produced by the sal trees. Description ''Shorea robusta'' can grow up to tall with a trunk diameter of . The leaves are 10–25 cm long and 5–15 cm broad. In wetter areas, sal is evergreen; in drier areas, it is dry-season deciduous, shedding most of the leaves from February t ...

Himalayan Subtropical Broadleaf Forests
The Himalayan subtropical broadleaf forests is an ecoregion that extends from the middle hills of central Nepal through Darjeeling into Bhutan and also into the Indian States of Uttar Pradesh and Bihar. It represents the east-west-directed band of subtropical broadleaf forest at an altitude of between along the Outer Himalayan Range, and includes several forest types traversing an east to west moisture gradient.Rawat, G. S., Wikramanayake, E. D. (2002''Himalayan subtropical broadleaf forests'' In: Wikramanayake, E. D. (ed.) ''Terrestrial ecoregions of the Indo-Pacific: a conservation assessment''. Island Press Geography The ecoregion covers an area of and is bisected by the Kali Gandaki River, which has gouged the world's deepest river valley through the Himalayan Range. It forms a critical link in the chain of interconnected Himalayan ecosystems, where altitudinal connectivity between the habitat types is important for ecosystem function.

Chir Pine
''Pinus roxburghii'', commonly known as chir pine or longleaf Indian pine, is a species of pine tree native to the Himalayas. It was named after William Roxburgh. Description ''Pinus roxburghii'' is a large tree reaching with a trunk diameter of up to , exceptionally . The bark is red-brown, thick and deeply fissured at the base of the trunk, thinner and flaky in the upper crown. The leaves are needle-like, in fascicles of three, very slender, long, and distinctly yellowish green. The cones are ovoid conic, long and broad at the base when closed, green at first, ripening glossy chestnut-brown when 24 months old. They open slowly over the next year or so, or after being heated by a forest fire, to release the seeds, opening to broad. The seeds are long, with a wing, and are wind- dispersed. Similar species ''Pinus roxburghii'' is closely related to '' P. canariensis'' (Canary Island pine), '' P. brutia'' (Turkish pine) and '' P. pinaster'' (maritime ...

Himalayan Subtropical Pine Forests
The Himalayan subtropical pine forests are a large subtropical coniferous forest ecoregion covering portions of Bhutan, India, Nepal, and Pakistan. Geography This huge pine forest stretches for 3000 km across the lower elevations of the great Himalaya range for almost its entire length including parts of Pakistan's Punjab Province in the west through Azad Kashmir, the northern Indian states of Jammu and Kashmir, Himachal Pradesh, Uttarakhand and Sikkim, Nepal and Bhutan, which is the eastern extent of the pine forest. Like so many Himalayan ecosystems the pine forests are split by the deep Kali Gandaki Gorge in Nepal, to the west of which the forest is slightly drier while it is wetter and thicker to the east where the monsoon rains coming off the Bay of Bengal bring more moisture. Flora The predominant flora of the ecoregion is a thin woodland of drought-resistant ''Pinus roxburghii'' trees with a ground cover of thick grass, as regular fires do not allow a shrubby underg ...

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 almost ...
