Introduction
The Nilgiri plateau carried a textbook case of ecological specialisation and exchange: four communities at different altitudes, each producing what the others could not, bound by hereditary partnership. Rivers described it in 1906 and Mandelbaum and Emeneau analysed it; almost none of it survives.

Body
1. The niches and specialisations: the Toda held the high grassland as buffalo pastoralists, living on dairy produce, with sacred herds and the dairy-temple, and cultivating nothing. The Kota occupied seven villages on the plateau as artisans — blacksmiths, potters, carpenters, leather workers and, crucially, musicians. The Kurumba lived on the wooded slopes as foragers and honey collectors, credited with sorcery. The Irula, lower still, cultivated ragi and gathered forest produce.
2. The exchange that bound them: the Kota supplied iron implements, pots and music; the Toda gave ghee and buffaloes; the Kurumba brought honey, forest produce and magical protection for fields and herds; the Irula supplied grain. Payment was in kind at harvest between hereditary partner households, not in cash. The bond was ritual as much as economic: Kota bands were obligatory at Toda funerals, and Kurumba sorcerers were engaged both to cause and to avert misfortune. Rank was clear, the Toda highest, the Kota lower for handling leather and carrion, the Kurumba feared rather than honoured.
3. The forces of change: British annexation from 1819, Ootacamund, and the conversion of Toda grazing land to coffee, tea, potato and eucalyptus; roads and cash markets; mill cloth and factory pots, which destroyed Kota craft; missions, schools and reservation employment; and finally the Nilgiri Biosphere Reserve and Mudumalai, which restricted Kurumba access to the forest.
4. The relationships now: the Toda number some two thousand with reduced herds, the Kota are teachers and government servants, the Kurumba sell honey through cooperatives, and the Irula work on plantations. All four are now classed as particularly vulnerable groups in Tamil Nadu.

Conclusion
Specialisation survived only where the state or the market paid for it. What remains of the system is ceremonial — the Kota band at a Toda funeral — while the economic interdependence that produced it has gone.
