In 2002 there were 401
tribal persons living in three settlements within IGWS&NP boundaries in the valley. This is an average population density of 3.65 persons/km2, 40% higher than the 2.6 persons/km2 living in all 36 tribal settlements in the entire 1769 km2 IGWS&NP. Their peaceful ancient culture in this area is increasingly fragmented as they assimilate modern
Tamil customs and values. The villages have no link roads, no electricity (some solar lamps have been installed recently), no running water, no government school, no medical facilities and no shops. In addition there are three villages within the valley watershed but outside the National Park boundaries:
Mannavanur pop. 5,927,
Kumbur pop. 500, and
Kilanavayal 124 families.
Thalinji Thalinji village at , near the bottom of the valley above the banks of the Ten Ar River, has about 150 houses (pop: m-168, f-155). Most of the people are Pulaiyar caste, early cultivators, but there are some
Malaimarasar tribal people, who do agriculture and coolie work. This place had some importance in medieval times, as there are mounds with 15th century ruins of a
Vijayanagar Dynasty dispersed among its many agricultural fields located inside a bend of the Ten Ar just below its junction with the Kumbar and Manalaar streams. It is ethnically more diverse than Talinji. Pulaiyar were the majority inhabitants of Manjampatti when the British gave land to the village for cultivation. About 15 families of Muthuvar, another "tribal" group, live in Manjampatti village where they do cultivation and labor work. Some
Theivar people, a widespread plains agricultural jaathi (caste), came to live in Manjampatti long ago and engage in agriculture on the village lands. There are also a few houses of other plains jaathis such as
Chakkliyar (originally leather-workers). Because of these jaathis, Manjampatti village has some features of plains Tamil villages such as eating of newer types of vegetables and having tea shops. Manjampatti comes under the
Mannavanur Panchayat and sends its Ward Member up to the monthly meetings. The people receive no benefit from the Panchayat, and prefer to rely on the Forest Department. Manjampatti falls under
Kodaikanal Taluk office, and the people must travel far to Kodaikanal for official services such as getting a ration card. The ration items (rice, sugar, kerosene) are sent to an agent on the Amaravaathi-Munnar Road (
SH 17) where the people go to collect them. The village has a small part-time general store selling cooking items and two part-time tea shops. There is a basic primary school of a type designed for tribal people, which is able to provide Transfer Certificates (TC) to students. There is a Forest Department Anti-Poaching Camp with four full-time staff. There is a polling station at the Hydro Matric Survey Building in Manjampatti for all voters from Manjampatti, Muthuvankudi and Mungilpallam (Mannavanur (r.v) Ward-5). The village has a Moopan (headman), assisted by a group of elder men, who organizes activities such as maintaining irrigation channels and resolving disputes, but this position is not recognized in the Panchayat system. The Moopan can be of any
caste, and serves as long as he has the confidence of the people. If someone commits a serious crime, the Moopan will turn the suspect over to the Forest Department, which will arrange for him to be detained by police on the plains. Manjampatti was given land for cultivation when the Reserved Forest was created and the families have kept their respective fields marked with the original stone boundaries. Villagers earlier practiced
shifting cultivation, growing
millets such as
raagi,
thinai and
kambu. Later the Forest Department forbade shifting cultivation and restricted cultivation to the allotted lands. The crops now are rice in rainy season and butter beans otherwise, though with a more diverse population a few vegetables such as eggplant and tomatoes are grown. Farmers here have to protect their crops from wild elephants, gaur, wild boar, deer and sometimes peacocks. A complex and well maintained system of small canals distributes water from the Manalar to irrigate the fields.
Muduvankudi is a neighboring village inhabited by Muduvar (Muthuvar), and is a 15-minute trek from Manjampatti.
Mungilpallam Mungilpallam (Moongilpallam) village at , at the headwaters of the TenAr, the third village going up the valley, is a hamlet of just 20 houses of Pulaiyar people (pop: m-22, f-18), on the north side and above the Kumbaar stream. They practice some shifting cultivation on their south facing slope. There is a steep cliff trail from here which leads east to Kumboor village at the end of the road from Kodaikanal. Since 1995, a registered Christian charity "Tribal Education and Medicare Vision" (Team Vision) has assisted the villagers to get identity cards and ration cards from the Revenue Department and Civil Supplies Department. Also, corrugated steel sheets were provided for home roofing. 18 new huts were erected in a new location in 1999. The Forest Department helped the villagers lay stones on the tortuous way to the village. They also erected two solar lamps. A kindergarten school was started and 20 children were enrolled in 1998. In 2005, 9 children from Mungilpallam were attending elementary and secondary school in Kodaikanal.
Maangapaarai is another remote settlement and highly inaccessible because of bison attacks. ==Geography==
