Central Deccan Plateau Dry Deciduous Forests Some of the larger species mentioned here are rare, as is the threatened Indian giant squirrel ("Ratufa indica"). The 300 species of birds include the globally threatened Jerdon's courser ("Rhinoptilus bitorquatus"), which was rediscovered in 1986 having been thought extinct for nearly a hundred years. About 80 percent of the natural habitat in the ecoregion has been lost. Several blocks of habitat larger than 5,000 km remain. Fifteen protected areas cover almost 3% of the ecoregion's area, with Nagarjunsagar-Srisailam Tiger Reserve as the largest.

Tibetan Plateau colonization leading to the full-time occupation of the plateau occurred much later than the previously thought 30,000 years ago. Since colonization of the Tibetan Plateau, Tibetan culture has adapted and flourished in the western, southern, and eastern regions of the plateau. The northern portion, the Changtang, is generally too high and cold to support permanent population. One of the most notable civilizations to have developed on the Tibetan Plateau is the Tibetan Empire from the 7th century to the 9th century AD. Monsoons are caused by the different amplitudes of surface temperature seasonal cycles between land and oceans. This differential
