Alpine vegetation in India is found in the:

Alpine vegetation is the vegetation found at high altitudes, above the tree line, where it is too cold and windy for trees to grow. In the Himalaya, alpine vegetation is generally found at altitudes above about 3,600 metres, up to the snow line.

In the Himalaya, the type of vegetation changes with altitude, just as it changes with latitude from the equator to the poles:

Up to about 1,000 metres: tropical moist deciduous forests, with trees such as sal and teak in the foothills.

1,000 to 2,000 metres: wet temperate forests with evergreen broad-leaved trees such as oak and chestnut.

1,500 to 3,000 metres: temperate coniferous forests with pine, deodar, silver fir, spruce and cedar.

3,000 to 3,600 metres: sub-alpine forests and trees such as silver fir, juniper, birch and rhododendron.

Above 3,600 metres: alpine vegetation, made up of shrubs, scrubs and alpine grasslands (meadows). Plants are small and grow close to the ground. Juniper, rhododendron, mosses and lichens are common at the higher levels.

Alpine meadows, such as the bugyals of Uttarakhand and the margs (such as Gulmarg and Sonamarg) of Kashmir, are used for grazing by nomadic herders such as the Gujjars, Bakarwals, Gaddis and Bhotiyas, who move their animals up in summer and down in winter (transhumance).

The Valley of Flowers National Park in Uttarakhand, famous for its alpine flowers, is part of a UNESCO World Heritage Site, together with Nanda Devi National Park.
