Name: Himalayas, Sanskrit for ‘abode of snow’
Geography: The Himalayas stretch across the northeastern
portion of India. They cover approximately 1,500 mi (2,400 km) and pass through
the nations of India, Pakistan, Afghanistan, China, Bhutan and Nepal. The
Himalayan range is made up of three parallel ranges often referred to as the
Greater Himalayas, the Lesser Himalayas, and the Outer Himalayas.
Ecology: While intimidating mountains like Everest and 2K
tend to dominate our perceptions of the region, the Himalayas are rich in
biodiversity. Climates range from tropical at the base of the mountains to
perennial snow and ice at the highest elevations. These complex and diverse
eco-regions are interconnected: an ecological threat to one is ultimately a
threat to many. Here are just a few examples of Himalayan ecology:
Montane Grasslands and Shrublands:
Western alpine shrubs and meadows can be found between 9,850
and 16,400 ft. These areas tend to have cold winters and mild summers that
allow for plant growth. Rhododendron plants cover the lower shrublands, while
the alpine meadows, directly above, host a range of flora in the warmer months.
Animals found in this region include the snow leopard, Himalayan tahr, musk
deer, and pikas.Temperate Coniferous Forest:
In the northeast, temperate sub-alpine conifer forests are
found at elevations of 8,200 to 13,800 ft. Located in the inner valley area,
these forests are protected from harsh monsoon conditions by surrounding
mountain ranges. The dominant tree types are pine, hemlock, spruce, and fir.
Animals found in this region include red pandas, takins, and musk deer.
Temperate Broadleaf and Mixed Forests:
Found in middle elevations of 6,600 to 9,800 ft. in the
eastern region are broadleaf and coniferous forests. These forests receive
almost 80 inches of annual rainfall, mostly during the monsoon season. In
addition to indigenous oaks and maples, plants like orchids, lichen, and ferns
also grow in the area. A huge range of wildlife, including over 500 species of
birds, are found here during the cooler seasons before they migrate to higher
elevations to escape the hot summers. This is also the primary home for golden
langur monkeys.
Tropical and Sub-tropical Broadleaf Forests:
Located at 1,650 to 3,300 ft. along a narrow strip of the
outer Himalayan range are the Himalayan sub-tropical broadleaf forests. Here
there is a wide range of plant life thanks to the areas varied topography, soil
types, and rainfall levels. Forest types include subtropical dry evergreen,
northern dry mixed deciduous forests, moist mixed deciduous forests,
subtropical broadleaf forests, northern tropical semi-evergreen forests, and
northern tropical wet evergreen forests. Wildlife includes many threatened
species including tigers and Asian elephants. More than 340 different species
of birds can be found in this region.
Highest peak: Mount Everest at 29,029 ft (8,848 m) is not only the highest peak in the Himalayas, but the highest peak on the entire planet.
Other famous peaks include Karakora (K2), Kailash,
Kanchenjunga, Nanga Parbat, Annapurna, and Manasklu.
Rivers: The Himalayas are the source for the Indus, the
Yangtze and the Ganga-Brahmaputra. All three are major river systems for the
continent of Asia.
The main rivers sourced in Himalayas are the Ganges, Indus,
Yarlung, Yangtze, Yellow, Mekong, and Nujiang.
Glaciers: The Himalayas are the third largest deposit of ice
and snow in the world, after Antarctica and the Arctic. There are approximately
15,000 glaciers located throughout the range. At 48 miles (72 km) in length,
the Himalayan Siachen glacier is the largest glacier outside the poles.
Other notable glaciers located in the Himalayas include the
Baltoro, Biafo, Nubra, and Hispur.
Additional Facts:
The Himalayas are
the result of tectonic plate motions that collided India into Tibet.
Because of the
great amount of tectonic motion still occurring at the site, the Himalayas have
a proportionally high number of earthquakes and tremors.
The Himalayas are
one of the youngest mountain ranges on the planet.
The range affects
air and water circulation systems, impacting the weather conditions in the
region.
The Himalayas
cover approximately 75% of Nepal.
Serving as a
natural barrier for tens of thousands of years, the range prevented early
interactions between the people of India and the people of China and Mongolia.
Mt. Everest was
named after Colonel Sir George Everest, a British surveyor who was based in
India during the early-to-mid-nineteenth century.
The Nepalese call
Mt. Everest “Samgarmatha” which can be translated as “Goddess of the Universe”
or “Forehead of the Sky.”
In 1953, Sir
Edmund Hillary and Sherpa mountaineer Tenzing Norgay were the first people to
successfully climb to the summit of Everest.
Despite its name,
the Snow Leopard – a Himalayan local – is actually most closely related to the
Tiger.
