 TMG are high elevation grasslands forming only 2% of all grasslands in the world.

Among their functions is regulating the global carbon cycle and serving as a source of water to downstream communities.

In India, TMG have even been classified as wastelands in forest management plans since they are unlikely to generate revenue, contrary to the timber (even if exotic) found in forests.

In the Western Ghats, 23% of montane grasslands were reportedly converted into invasive exotic tree cover over a period of 44 years.
