Tussock grasses or bunch grasses are found as native plants in natural ecosystems, as forage in pastures, and as ornamental grasses in gardens.Tussock and bunch grasses, in the Poaceae family, are grasses that usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants usually, they live more than one season.

Many species have long roots that may reach 2-metre (6.6 ft) or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists.

Tussock and bunch grasses occur in almost any habitat where other grasses are found, including: grasslands, savannas and prairies, wetlands and estuaries, riparian zones, shrublands and scrublands, woodlands and forests, montane and alpine zones, tundra and dunes, and deserts.

In geology, permafrost or cryotic soil is soil at or below the freezing point of water 0 °C (32 °F) for two or more years. Most permafrost is located in high latitudes (in and around the Arctic and Antarctic regions), but alpine permafrost may exist at high altitudes in much lower latitudes. Ground ice is not always present, as may be in the case of nonporous bedrock, but it frequently occurs and it may be in amounts exceeding the potential hydraulic saturation of the ground material. Permafrost accounts for 0.022% of total water on earth and exists in 24% of exposed land in the Northern Hemisphere.It also occurs subsea on the continental shelves of the continents surrounding the Arctic Ocean, portions of which were exposed during the last glacial period.

A global temperature rise of 1.5 °C (2.7 °F) above current levels would be enough to start the thawing of permafrost in Siberia, according to one group of scientists.

Ladakh (“land of high passes”) is a region of India in the state of Jammu and Kashmir that currently extends from the Kuen Lun mountain range to the main Great Himalayas to the south, inhabited by people of Indo-Aryan and Tibetan descent. It is one of the most sparsely populated regions in Jammu and Kashmir and its culture and history are closely related to that of Tibet.

Historically, the region included the Baltistan (Baltiyul) valleys (now mostly in Pakistani Kashmir), the entire upper Indus Valley, the remote Zanskar, Lahaul and Spiti to the south, much of Ngari including the Rudok region and Guge in the east, Aksai Chin in the northeast (extending to the Kun Lun Mountains), and the Nubra Valley to the north over Khardong La in the Ladakh Range. Contemporary Ladakh borders Tibet to the east, the Lahaul and Spiti regions to the south, the Vale of Kashmir, Jammu and Baltiyul regions to the west, and the southwest corner of Xinjiang across the Karakoram Pass in the far north. Ladakh is renowned for its remote mountain beauty and culture. Aksai Chin is one of the disputed border areas between China and India.It is administered by China as part of Hotan County but is also claimed by India as a part of the Ladakh region of the state of Jammu and Kashmir. In 1962 China and India fought a brief war over Aksai Chin and Arunachal Pradesh, but in 1993 and 1996 the two countries signed agreements to respect the Line of Actual Control.

In the past Ladakh gained importance from its strategic location at the crossroads of important trade routes, but since the Chinese authorities closed the borders with Tibet and Central Asia in the 1960s, international trade has dwindled except for tourism. Since 1974, the Government of India has successfully encouraged tourism in Ladakh. Since Ladakh is a part of strategically important Jammu and Kashmir, the Indian military maintains a strong presence in the region.

The largest town in Ladakh is Leh. Almost half of Ladakhis are Tibetan Buddhists and the rest are mostly Shia Muslims.Leh is followed by Kargil as the largest town in Ladakh.Some Ladakhi activists have in recent times called for Ladakh to be constituted as a union territory because of perceived unfair treatment by Kashmir and Ladakh’s cultural differences with predominantly Muslim Kashmir.
In terms of pronunciation, the use of

“Ladakh, the Persian transliteration of the Tibetan La-dvags, is warranted by the pronunciation of the word in several Tibetan districts.”

The River Tummel is a river in Perth and Kinross, Scotland.

Schiehallion (Scottish Gaelic: Sìdh Chailleann) is a prominent mountain in Perth and Kinross, Scotland. Schiehallion has a rich botanical life, interesting archaeology, and a unique place in scientific history for an 18th-century experiment in ‘weighing the world’. The mountain’s popularity amongst walkers led to erosion on its footpath and extensive repairs were undertaken in 2001.
