The Kurumbas are found in southern India, in the states of Tamil Nadu, Kerala and Karnataka. Etymologically Kurumba means one who tends sheep.
In Tamil Nadu, they are only found in the Nilgiri District of the state, where they have many sub-groups / divisions, namely the Alu Kurumbas, Betta Kurumbas, Jenu Kurumbas, Mullu Kurumbas and the Urali Kurumbas. Different sub-groups maintain a distinctive ethnic identity and speak different dialects, some containing more Kannada and Tamil words, some speaking Kannada and other speaking Malayalam.
CTRD works mainly with the Beta Kurumbas, and to a lesser extent with the Jenu Kurumbas.
The Kurumbas are extremely old inhabitants in the Nilgiri district, although their origin is debatable. They claim to originate from the boarders of Wynyard (Kerala state), Gunwale (Karnataka state) and Attala (Kerala state), in and around the Nilgiri plateau.
The Betta Kurumbas and the Jenu Kurumbas live in the Gudalur Taluk, in and around the Mudumalai Wild Life sanctuary.
