The Palani Hills are a mountain range in the southern Indian states of Tamil Nadu and Kerala. The Palani Hills are an eastward extension of the Western Ghats ranges, which run parallel to the west coast of India. The Palani Hills adjoin with the high Anamalai range on the west and extend east into the plains of Tamil Nadu, covering an area of 2,068 square kilometres (798 sq mi). The highest part of the range is in the southwest, and reaches 1,800-2,500 metres (5,906-8,202 feet) elevation; the eastern extension of the range is made up of hills 1,000-1,500 m (3,281-4,921 ft) high. [1]
It is also home to the main temple of Murugan, who is worshipped as a major deity in Tamil Nadu.
The Palani Hills Wildlife Sanctuary and National Park is a proposed protected area in Dindigul District, Tamil Nadu. The park will be an upgrade and expansion of the 736.87 km2 (284.51 sq mi) Palani Kodaikanal Wildlife Sanctuary which was to be established in 2008. [2] [3] [4] The park includes about 36% of the 2,068 km2 (798 sq mi) in the Palani Hills. The park is located between latitude 10°7'–10°28' N and longitude 77°16'–77°46' E. Central location is 1.5 kilometres (0.93 mi) east northeast of Silver Cascade Waterfall and 4 km (2.5 mi) E X NE of Kodaikanal Lake.
The Palani Hills derive their name from the ancient temple town of Palani (பழநி in Tamil) located at the northern base of the hills.
In 1906, the great undulating plateau on top of the Palanis comprising four forest ranges were consolidated under the Indian Forest Act of 1878 and designated by the British Government as a single reserve forest, from Kodaikanal town to the Kerala state border in the west and the Bodinayakkanur town limits to the south, and given the name of the Ampthill Downs. It was over 140 square kilometres (53 sq mi) in extent and about one quarter of it then consisted of sholas and three quarters was open, rolling, grassy downs. [5]
The Ampthill Downs area is now named Upper Palani Shola Reserved Forest and totals 145.7 square kilometres (56.3 sq mi) (36,000 acres) of forest land. It is the largest reserve forest division in the Palani Hills. The core of the proposed Kodaikanal Wildlife Sanctuary awaiting government notification is located in this division. [6]
In 1988, the new 50 square kilometres (19 sq mi) Kodaikanal-Berijam Wildlife Sanctuary was included in the protected area proposals considered to be of national priority status by the Wildlife Institute of India. [7] In the early 1990s, the Tamil Nadu Forest Department submitted a proposal to the State government to protect much of the Palani Hills by declaring the area a wildlife sanctuary or a national park. [8]
The proposed park area includes only reserve forest land. These forests are already among the protected areas of Tamil Nadu. Their upgrade to Wildlife Sanctuary and National Park will increase their IUCN status from level VI - Protected Area with Sustainable Use of Natural Resources to IV - Habitat/Species Management Area or II - National Park and improve the habitat and wildlife conservation of the area.
The sanctuary has been under consideration of the Government of India in consultation with the Government of Tamil Nadu since 1999. [9] The actual park boundaries have not been finalized. In 2007, proposals for declaration of Kodaikanal Wildlife Sanctuary were under consideration of the Government. [10]
On 13 August 2012, in an apparent change away from plans for notification of parts of the Palani Hills as a separate wildlife sanctuary, the Tamil Nadu Gazette notification attached parts of Kodaikanal and Dindigul divisions of reserve forests to the buffer zone of Annamalai Tiger Reserve. About 5155.42 hectares of forest land belonging to Palani Hills Northern Slope, Andipatty reserve forest, 4,344.53 acres in Kudraiyar block forest and 5,548.49 hectares in Mannavanur Range in Kodaikanal will be included in the buffer zone. The villages and hamlets that now form part of the Palani Hills buffer zone are Poondi, Mannavanur, Kilavarai, Polur, Kavunchi, Kumbur, Kilanavayal, Kukkal, Pazhamputhur and Puthurpuram. [11] [12]
The increasingly important economic role of Eco-tourism, including trekking, hiking, camping, mountaineering, rock climbing and bird watching may help the local populace to welcome this new Protected area. It remains to be seen whether the Wildlife Sanctuary and National Park will stimulate or stifle commercial development and tourism. The decision to finally establish the park must balance short term financial benefits of the status quo versus long term stability of the natural and human community.
Vandaravu peak is the highest peak in the Palani hills. The range lies between the Cumbum Valley on the south, which is drained by the Vaigai River and its upper tributaries, and the Kongunadu region to the north. The northern slopes are drained by the Shanmukha River, Nanganji River, and Kodavanar River, which are tributaries of the Kaveri River. The range lies mostly within Dindigul district, except in the western portion, where it forms the boundary between Dindigul district and Theni district to the south and Idukki District to the south west. The hill station of Kodaikanal lies in the southern central portion of the range. Palani Hills joined with Anamalai Hills and Cardamom Hills at Anamudi peak in Kerala state. Vattavada in Kerala is a part of Palani hills.
The Palni Hills are an eastward spur of the Western Ghats with a maximum east–west length of 65 kilometres (40 mi), and a north–south width of 40 kilometres (25 mi). Area is 2,064 square kilometres (797 sq mi). These hills rise in steep escarpments to a high undulating plateau ranging from 1,600 metres (5,200 ft) to over 2,000 metres (6,600 ft) elevation. [13]
The western extremity of the park is contiguous with the Manjampatti Valley core area of the Indira Gandhi Wildlife Sanctuary and National Park and with The Chinnar Wildlife Sanctuary in Kerala. The Kurinjimala Sanctuary in Kerala borders the southwestern corner of the park. [14] These Wildlife Sanctuaries are adjacent to the recently established Eravikulam National Park.
The park area includes only reserve forest land, including Palni Hills Northern Slope East, Kallar, Palni Hills Southern Slope East, Upper Palni Shola, Allinagaram, and Palni Hills Northern Slope West Reserve Forests in the Dindigul [15] and Kodaikanal Forest Divisions. [16]
The lower elevations of the Palani Hills, between 250 and 1,000 m (820-3,281 ft), are part of the South Western Ghats moist deciduous forests ecoregion. Above 1,000 m (3,281 ft), the deciduous forests transition to the evergreen South Western Ghats montane rain forests. In the highest portions of the range, above 2,000 m (6,562 ft), the montane rainforests give way to shola -grassland mosaic, made up of frost-tolerant montane grasslands interspersed with pockets of stunted shola forests. The hills extend into Kerala as Pampadum Shola National Park.
The Palani Hills are currently subject to increasing development pressure as it is under developed for a long time. The Palani Hills Conservation Council, a non-governmental organization headquartered in Kodaikanal, was founded in 1985. In the early 1990s the Tamil Nadu Forest Department proposed to the Tamil Nadu state government that much of the range be granted protected status as a wildlife sanctuary or Palani Hills Wildlife Sanctuary and National Park. [17]
The Palani Hills are formed of pre-Cambrian gneisses, charnockites and schists; they are among the oldest mountain ranges in India. [18] The park is an eastward extension of the Western Ghats hills formed by separation of the India-Madagascar-Seychelles blocks of East Gondwana in the Early Cretaceous period about 120 million years ago. [19]
It is surrounded to the north, east and south by the Deccan Plateau formed later in the massive Deccan Traps eruption 66 million years ago as India drifted over the Reunion Hotspot. [20]
The Palani hills are most prominent towards the west, ranging from 1,800 metres (5,900 ft) to 2,553 metres (8,376 ft) (5,906 ft - 8,376 ft). The ten most prominent peaks are:
The hill station of Kodaikanal stands in a 2,195 m (7,202 ft) high basin at the southern edge of the central part. The eastern end of the park is made of hills 1000–1500 m (3,281 ft - 4,921 ft) high. [21]
The Tamil Nadu Department of Geology and Mining has completed detailed Geo-Technical Studies of the Palni Hills determining moderate to high landslide danger in much of the area. [22]
There are many waterfalls throughout the park which are popular tourist attractions. Some of the prominent falls associated with the park are: (Distances are referenced from km 0.0 at the bund (dam) on northeast end of Kodaikanal lake at .)

The Palani Hills have a montane tropical monsoon climate which varies from west to east. Generally, as one proceeds from the Kerala border in the west to the foothills in the east, average rainfall decreases and temperature increases. Compared to the Deccan plateau and the southwestern coastal plains, temperatures vary from moderate to quite cool. In the central Palani Hills at Kodaikanal, during March to May, the temperature range is between 10.1 and 20.9 °C (50.2 and 69.6 °F). The temperature can rise to a high of 35 °C (95 °F). During December to February it is between 8.1 and 18.6 °C (46.6 and 65.5 °F). In January, night temperatures sometimes drop below freezing, and thin ice is seen on lake edges in the early morning. [26]
The climate of the upper Palnis has four clearly defined seasons:
The average annual rainfall is 1,617 millimetres (63.7 in), mostly during the north-east monsoon. [28] [29]
Nomadic Paliyan tribes people have been seen living in some of the several caves in Manjampatti Valley. Paliyan people can be seen near Kukal Cave. The Tamil speaking Pulayan are referred to as the MalaPulayans, a group categorized as scheduled caste by State government of Tamil Nadu. Their traditional livelihood is foraging yams and small gaming in the nearby forest areas combined with cultivation of several species of minor millets in small plots located near their hamlets to meet their subsistence requirements.
They live in small hamlets in huts and government constructed colonies. The sedentary life started with the construction of group houses by the government in the early sixties. The community is vertically divided into two sub divisions called Koora and Kanni, further subdivided into 47 sub sects. Each sub sect is called Kootams, which regulates certain social events. Each kootam has its own deity, which is common to the entire group and once yearly the members of the same kootam assemble to worship the deity. [30]
Many native tribals in the Palani Hills have partially assimilated modern culture but are marginalized on the fringes of society. Their social, economic and physical survival has become a difficult challenge for them and several public and private agencies. Their ancient culture in this area is well documented. [31] [32]
Relics and artifacts of the Paliyan tribes people can be seen in the Shenbaganur Museum. [33]
The Palani hills are the easternmost part of the Western Ghats of India, which is one of the 25 biodiversity hotspots of the world. Some of the very rare and endangered plants and animals of India are found here. including intact relics of primary indigenous vegetation and a large number of non-native plants. [35]
The hills may be divided into four distinct vertical zones comprising distinct Ecoregions with a wide diversity of Endemic species.
Mammals: Wild are common in areas away from human habitation and cultivation.
Threatened species in the park area include: Bengal tiger, Indian elephant, Indian leopard, gaur (wild ox), Nilgiri tahr and grizzled giant squirrel.
Endangered Bengal tiger populations in the adjacent Project Tiger reserves of Anamalai Tiger Reserve and the Kalakkad Mundanthurai Tiger Reserve [36] in the Agasthyamalai hills could expand back into this area when it is better protected. In February 2010, tigers were sighted in Kodaikanal forests during a six-day carnivore signs survey. A tigress and her cub were spotted playing in the wild. Forest Department officials are studying survey data to estimate the local tiger population based on indirect evidence like pug marks, scats and scratches. [37] Amphibians and reptiles: Several little-known and endemic species of amphibians like Raorchestes dubois, Ghatixalus asterops, Micrixalus nigraventris, Indirana leptodactyla, Nyctibatrachus deccanensis and reptiles like Salea anamallayana, Hemidactylus anamallensis, Kaestlea palnica, Kaestlea travancorica, Ristella rurkii, Platyplectrurus madurensis, Teretrurus rhodogaster, Uropeltis pulneyensis, Uropeltis broughami, Uropeltis woodmasoni, Ahaetulla dispar, Boiga dightoni and Trimeresurus macrolepis occur in this sanctuary. Other more widespread species of herpetofauna also occur lower down.
Plants:
Moist areas exist along the ravines and in the sheltered pockets of high elevation shola forests around 2,000 metres (6,600 ft). These sholas are often hotspots of endemic plant life. Notable among these is Pambar Shola. The Pambar Shola, draining to the Pambar River, is now reduced to less than 3 kilometres (1.9 mi) in circumference. It contains several rare and endemic plant species including: Sonerila pulneyensis: a delicate Melastomataceae succulent herb endemic to Pambar Shola, Hoya wightii ssp. pulneyensis: a succulent vine with waxy flowers endemic to Pambar Shola', Plectranthus bourneate: a succulent herb endemic to Pambar Shola, Trichoglottis tenera: an epiphytic orchid. Pambar Shola is its major habitat, Phyllanthus chandrabosei: a shrub endemic to Pambar Shola, Huperzia sp.: a fern ally endemic to Pambar Shola, Selaginella sp.: a delicate creeping fern endemic to Pambar Shola, Psydraxficiformis : a tree, until recently thought extinct, Utleria salicifolia: only one clump known on the Palni hills, Elaeocarpus blascoi : a tree believed extinct until this year, Cyathea crinita: tree fern, highly endangered (Botanical Survey of India), Aeschynanthus perrottetii: known only from one other shola in the Palni hills, Eulophia sp.: a new species for the Palni hills first collected in April 2000, Actinodapohne bourneae: Laurel tree believed extinct (Botanical Survey of India). Two trees found in Pambar Shola, Ceropegia thwaitesii: vine, vulnerable, endemic to Pambar shola, Pimpinella pulneyensis: scarce, Exacum anamallayannum: gentian, only one other known location in Palni hills.

Kurinji flowers (Strobilanthes kunthiana) which blossom in spectacular fields of violet only once in 12 years are threatened. [40]
There is decreasing biodiversity, deforestation, grasslands destruction, monoculture tree plantations, and invasive exotic plant species in the park. There is sewage pollution, solid waste pollution and mercury contamination, [41] and mercury pollution. There is also sound pollution, visual pollution, uncontrolled tourism, overdevelopment and lake eutrophication in and near Kodaikanal town. The Government of Tamil Nadu and several local NGO conservation groups are actively working to reduce some of these threats:
A sum of Rs.1327.50 lakhs has been released for this purpose during 2006–2007. [44]
The Kodaikanal Division Forest Office offers a book called Kodaikanal Beauty in Wilderness, which has a list and map of local treks in the Kodaikanal area. Several trekking destinations are accessible from the Kodaikanal–Munnar Road. Permission from the Forest Department is necessary to visit areas deep inside the forests and for trekking in forests. Forest rest houses are available with advance reservation at Kodaikkanal, Poombarai, Kukkal, Kavunji, Berijam and Devadanapatty.

Situated in the Nilgiri hills, it is known by the epithet "Queen of Hill Stations", and is a popular tourist destination.
Kodaikanal is a municipality and hill station in Dindigul district in the state of Tamil Nadu, India. It is situated at an altitude of 2,225 m (7,300 ft) in the Palani hills of the Western Ghats. Kodaikanal was established in 1845 to serve as a refuge from the high temperatures and tropical diseases during the summer in the plains. It is a popular tourist destination and is referred to as the "Princess of Hill stations" with much of the local economy is based on the hospitality industry serving tourism. As per the 2011 census, the city had a population of 36,501.
The Biligirirangana Hills or Biligirirangan Hills is a hill range situated in Chamarajanagar District in south-western Karnataka, at its border with Tamil Nadu in South India. The area is called Biligiri Ranganatha Swamy Temple Wildlife Sanctuary or simply BRT Wildlife Sanctuary. It is a protected reserve under the Wildlife Protection Act of 1972. Being close to the Eastern Ghats as well as the Western Ghats, the sanctuary has floral and faunal associations with both regions. The site was declared a tiger reserve in January 2011 by the Government of Karnataka, a few months after approval from India's National Tiger Conservation Authority.
The Cardamom Hills or Yela Mala are mountain range of southern India and part of the southern Western Ghats located in Idukki district, Kerala, India. Their name comes from the cardamom spice grown in much of the hills' cool elevation, which also supports pepper and coffee. The Western Ghats and Periyar Sub-Cluster including the Cardamom Hills are UNESCO World Heritage Sites.
The Nilgiri Biosphere Reserve is a biosphere reserve in the Nilgiri Mountains of the Western Ghats in South India. It is the largest protected forest area in India, spreading across Tamil Nadu, Karnataka and Kerala. It includes the protected areas Mudumalai National Park, Mukurthi National Park, Sathyamangalam Wildlife Sanctuary in Tamil Nadu; Nagarhole National Park, Bandipur National Park, both in Karnataka; Silent Valley National Park, Aralam Wildlife Sanctuary, Wayanad Wildlife Sanctuary, and Karimpuzha Wildlife Sanctuary in Kerala.
Periyar, IPA:[peɾijɐːr], is the longest river and the river with the largest discharge potential in the Indian state of Kerala. It is one of the few perennial rivers in the region and provides drinking water for several major towns. The Periyar is of utmost significance to the economy of Kerala. It generates a significant proportion of Kerala's electrical power via the Idukki Dam and flows along a region of industrial and commercial activity. The river also provides water for irrigation and domestic use throughout its course besides supporting a rich fishery. Due to these reasons, the river has been named the "Lifeline of Kerala". Kochi city, in the vicinity of the river mouth, draws its water supply from Aluva, an upstream site sufficiently free of seawater intrusion. Twenty five percent of Kerala's industries are along the banks of the Periyar. These are mostly crowded within a stretch of 5 kilometres (3 mi) in the Eloor-Edayar region (Udhyogamandal), about 10 kilometres (6 mi) north of Kochi harbor.
The Anamala or Anaimalai, also known as the Elephant Mountains, are a range of mountains in the southern Western Ghats of central Kerala and span the border of western Tamil Nadu in Southern India. The name anamala is derived from the Malayalam word aana and the Tamil word yaanai, meaning elephant, or from tribal languages. Mala or Malai means 'mountain', and thus literally translatable as 'Elephant mountain'.
Anaimalai Tiger Reserve, earlier known as Indira Gandhi Wildlife Sanctuary and National Park and as Anaimalai Wildlife Sanctuary, is a protected area in the Anaimalai Hills of Pollachi and Valparai taluks of Coimbatore District and Udumalaipettai taluk in Tiruppur District, Tamil Nadu, India. The Tamil Nadu Environment and Forests Department by a notification dated 27 June 2007, declared an extent of 958.59 km2 that encompassed the erstwhile IGWLS&NP or Anaimalai Wildlife Sanctuary, as Anaimalai Tiger Reserve under the Wildlife Protection Act, 1972. According to the National Tiger Conservation Authority, the Reserve presently includes a core area of 958.59 km2 and buffer/peripheral area of 521.28 km2 forming a total area of 1479.87 km2.
Manjampatti Valley is a 110.9 km2 (42.8 sq mi) protected area in the eastern end of Indira Gandhi Wildlife Sanctuary and National Park (IGWS&NP) in Tirupur District, Tamil Nadu, South India. It is a pristine drainage basin of shola and montane rainforest with high biodiversity recently threatened by illegal land clearing and cultivation.
Chinnar Wildlife Sanctuary is located 18 km north of Marayoor on State Highway 17 in the Marayoor and Kanthalloor panchayats of Devikulam taluk in the Idukki district of India's Kerala state. It is one of 18 wildlife sanctuaries among the protected areas of Kerala.
Pampadum Shola National Park is the smallest national park in Idukki district of Kerala in India. It is on the border with Kodaikanal, Dindigul district of Tamil Nadu. The park is administered by the Kerala Department of Forests and Wildlife, Munnar Wildlife Division, together with the nearby Mathikettan Shola National Park, Eravikulam National Park, Anamudi Shola National Park, Chinnar Wildlife Sanctuary and the Kurinjimala Sanctuary. The park adjoins the Allinagaram Reserved Forest within the proposed Palani Hills Wildlife Sanctuary and National Park.It is a part of Palani hills stretched up to Vandaravu peak. The Westerns Ghats, Anamalai Sub-Cluster, including these parks, is under consideration by the UNESCO World Heritage Committee for selection as a World Heritage Site.
The Pothigai Hills, also known as Agasthiyar Mountain is a 1,866-metre (6,122 ft)-tall peak in the southern part of the Western Ghats or Sahyadri of South India. The peak lies in Tirunelveli District of Tamil Nadu near the border of Kerala.
Kodaikanal Lake, also known as Kodai Lake, is a manmade lake located in the Kodaikanal city in Dindigul district in Tamil Nadu, India. Sir Vere Henry Levinge, the then Collector of Madurai, was instrumental in creating the lake in 1863, amidst the Kodaikanal town which was developed by the British and early missionaries from USA. The lake is said to be Kodaikanal's most popular geographic landmark and tourist attraction.
Kookal is a Panchayat village of terrace farmers at the far western end of the Palani Hills in Kodaikanal block of Dindigul district, Tamil Nadu state, South India. It is 40 kilometres (25 mi) from Kodaikanal at: 10°17′9″N77°21′48″E. Elevation is 1,890 metres (6,200 ft). Kookal is notable for the high biodiversity of the area.
Berijam Lake is a reservoir near Kodaikanal town in Dindigul district of Tamil Nadu, South India. It is at the old site of "Fort Hamilton", in the upper Palani hills. The lake, created by a dam with sluice outlets, is part of a micro–watershed development project. Periyakulam town, 18.7 kilometres (11.6 mi) to the SE, gets its public drinking water from the lake. The lake's water quality is excellent.
The Kodaikanal–Munnar Road was located in Dindigul District and Theni District of Tamil Nadu and Idukki district of Kerala in South India. It covers 81 kilometers (50 mi) from Kodaikanal to Munnar. The road was improved by the British in 1942 as an evacuation route in preparation for a possible Japanese invasion of South India. With a maximum elevation of 2,480 meters (8,140 ft) just south of Vandaravu Peak, it was among the highest roads in India, south of the Himalayas, prior to its closure in 1990.
Karian Shola National Park is a protected area in the Western Ghats, India, nominated as a national park in 1989. The Western Ghats are a chain of mountains running down the west of India parallel with the coast some 30 to 50 km inland. They are not true mountains, but the edge of a fault that resulted about 150 million years ago as the subcontinent of India split from Gondwanaland. They are older than the Himalayan mountain range and are clothed in ancient forests. They influence the weather in India as they intercept the incoming monsoon storm systems. The greatest rainfall occurs between June and September during the southwest monsoon, with lesser amounts falling in the northeast monsoon between October and November. The Western Ghats are a UNESCO World Heritage Site and are considered to be one of the eight most important "hotspots" of biological diversity in the world.
Sathyamangalam Tiger Reserve is a protected area and tiger reserve located along the area straddling both the Western Ghats and Eastern Ghats in the Erode district of the Indian state of Tamil Nadu. The Sathyamangalam Forest Division is part of the Bramhagiri-Nilgiris-Eastern Ghats Elephant Reserve notified in 2003. In 2008, part of the Sathyamangalam Forest Division was declared a wildlife sanctuary, which was further enlarged in 2011 to cover a forest area of 1,411.6 km2 (545.0 sq mi). It is the largest wildlife sanctuary in Tamil Nadu. In 2013, an area of 1,408.6 km2 (543.9 sq mi) of the erstwhile sanctuary was notified as a tiger reserve and it was the fourth tiger reserve established in the state as a part of Project Tiger.
Sigur Plateau is a plateau in the north and east of Nilgiri District in the Nilgiri Hills of Tamil Nadu, South India. It covers the 778.8 square kilometres (300.7 sq mi) portion of the Moyar River drainage basin on the northern slopes of the Nilgiri Hills, south of the Moyar River.
