Mudumalai National Park is a national park in the Nilgiri Mountains in Tamil Nadu in southern India. It covers 321 km2 (124 sq mi) at an elevation range of 850–1,250 m (2,790–4,100 ft) in the Nilgiri District and shares boundaries with the states of Karnataka and Kerala. A part of this area has been protected since 1940. The national park has been part of Nilgiri Biosphere Reserve since 1986 and was declared a tiger reserve together with a buffer zone of 367.59 km2 (141.93 sq mi) in 2007.
It receives an annual rainfall of about 1,420 mm (56 in) and harbours tropical and subtropical moist broadleaf forests with 498 plant species, at least 266 bird species, 18 carnivore and 10 herbivore species. It is drained by the Moyar River and several tributaries, which harbour 38 fish species.
Traffic on three public roads passing through the national park has caused significant roadkills of mammals, reptiles and amphibians. The park's northern part has been affected by several wildfires since 1999.
History
The word Mudumalai is a Tamil word with முது 'mutu' meaning old, ancient, original; and முதுகாடு 'mudhukadu' meaning ancient forest.[1] The word மலை 'malai' means hill or mountain.[2]
The name 'Mudumalai forest' was already in use when the British Government rented the forest in 1857 for logging purposes from the Raja of Neelambur.[3]
In 1914, large forest tracts on the Sigur Plateau were declared as reserve forest for systematic logging. An area of about 60 km2 (23 sq mi) was established as Mudumalai Wildlife Sanctuary in 1940.[4] The sanctuary was enlarged in 1977 and incorporated into Nilgiri Biosphere Reserve in 1986.[4]
It was declared as a Tiger Reserve under Project Tiger in April 2007 and notified as 'Critical Tiger Habitat' in December 2007. At the time, 1947 people lived in 28 hamlets inside the reserve; they kept about 1,060 cattle. In 2010, it was proposed to resettle them.[5] This notification was criticised by activists and conservationists as having been intransparent and undemocratic.[6]
Mudumalai National Park covers 321 km2 (124 sq mi) in the eastern hills of the Western Ghats at an elevation range of 850–1,250 m (2,790–4,100 ft); it is bordered in the west by Wayanad Wildlife Sanctuary, in the north by Bandipur National Park and in the east by Sigur Reserve Forest.[4] In the south, it is bordered by Singara Reserve Forest.[9] The Moyar River enters the national park in the south and is joined by five tributaries.[10] Together they drain this area, and several artificial waterholes provide drinking water for wildlife during dry seasons.[9]
The original national park area together with a surrounding buffer zone of 367.59 km2 (141.93 sq mi) was designated as the Mudumalai Tiger Reserve.[11][12]
Mudumalai National Park receives about 1,420 mm (56 in) rainfall annually, most of it during the southwest monsoon season from June to September. The temperature drops during the cool season from December to January, but rises during April to June, which are the hottest months.[14]
Annual precipitation ranges from 1,100 mm (43 in) in the south and west to 600 mm (24 in) in the east.[17]
During the major flowering season, 394 nests of the giant honey bee (Apis dorsata) were detected in the park between January and June 2007; bee colonies comprised an average of 19 nests, mostly built in large trees.[24]
Mammals
A survey carried out between November 2008 and February 2009 revealed that about 29 Indian leopards (Panthera pardus fusca) and 19 Bengal tigers (P. tigris tigris) lived in the park's core area of 107 km2 (41 sq mi).[25] As of 2018, the tiger population in the wider Mudumalai Tiger Reserve was estimated to comprise 103 resident individuals.[12]Jungle cat (Felis chaus), rusty-spotted cat (Prionailurus rubiginosus) and leopard cat (P. bengalensis) were recorded during camera trap surveys in 2010–2011 and 2018.[26][12]
Two dhole (Cuon alpinus) packs were monitored during 1989–1993 and had home ranges of 83.3 and 54.2 km2 (32.2 and 20.9 sq mi); packs comprised between four and 25 individuals during this period.[27]Golden jackal (Canis aureus), and Nilgiri marten (Martes gwatkinsii) were also recorded in 2018.[12]
Scat of sloth bear (Melursus ursinus) collected along forest roads and animal trails contained remains of 18 plant species with golden shower (Cassia fistula), Indian plum (Zizyphus mauritiana) and clammy cherry (Cordia obliqua) forming the bulk of its diet apart from fungus-growing termites (Odontotermes), fire ants and honey bees.[28]Small Indian civet (Viverricula indica), Asian palm civet (Paradoxurus hermaphroditus) and brown palm civet (P. jerdoni) live in both deciduous and semi-evergreen forest patches; ruddy mongoose (Urva smithii) lives foremost in deciduous forest, whereas stripe-necked mongoose (U. vitticollis) frequents riverine areas, and Indian grey mongooseU. edwardsii open habitats.[29] The mongooses forage foremost for pill millipedes, dung beetles, fruits, small rodents, birds and reptiles.[30]Smooth-coated otter (Lutrogale perspicillata) groups were observed along the Moyar River in 2010 and 2011.[29] Their habitat preference was studied between 2015 and 2017; the groups preferred rocky areas near fast flowing water with loose sand and little vegetation cover.[31]
The Asian elephant is the largest mammal in the park with an estimated 536–1,001 individuals in 25 herds in 2000.[32] Herds comprise up to 22 individuals. The gaur (Bos gaurus) is the largest ungulate in the park, with herds of up to 42 individuals that frequent foremost grasslands in the vicinity of water sources.[33]
The sambar deer (Cervus unicolor) forms smaller groups of up to five individuals, but also congregates in groups of up to 45 individuals in the wet season. The chital (Axis axis) forms large groups of at least 35 individuals, with some herds increasing to more than 100 members in the wet season.[34]
Chital, Indian spotted chevrotain (Moschiola indica) and Indian muntjac (Muntiacus muntjak) have been recorded eating fallen fruit of the Indian gooseberry in a forest monitoring plot; they are therefore considered to be the primary seed dispersers in the park.[35] Present are also four-horned antelope (Tetracerus quadricornis), blackbuck (Antilope cervicapra), wild boar (Sus scrofa), Indian pangolin (Manis crassicaudata) and Indian crested porcupine (Hystrix indica).[12]
Indian giant squirrel
Four bonnet macaque (Macaca radiata) troops were studied in 1997, which ranged in size from 28 to 35 members and lived in sympatry with gray langur (Semnopithecus entellus) troops.[36]
A troop in the Moyar River valley foraged on leaves, flowers and fruits of several tree and shrub species including tamarind (Tamarindus indica), banyan fig (Ficus benghalensis), wild jujube (Ziziphus oenoplia), neem (Azadirachta indica), kaayam (Memecylon edule) and indigoberry (Randia malabarica), but also consumed herbs, crickets and grasshoppers.[37]
The range of the Indian giant squirrel (Ratufa indica) is continuous in the national park's moist deciduous forest; in the drier eastern part, it inhabits foremost riverine habitat with contiguous canopy. It builds nests in trees with a mean canopy height of 10.6 m (35 ft) and feeds on 25 plant species including teak, Indian laurel and Grewia tiliifolia.[38]
The Indian giant flying squirrel (Petaurista philippensis) inhabits foremost moist deciduous forest with old trees of a mean 12.9 m (42 ft) height, a mean density of 499 trees/ha (202 trees/acre) and a canopy height of at least 6.86 m (22.5 ft).[39]
In 2013, a painted bat (Kerivoula picta) was sighted in the eastern part of the tiger reserve.[40]
Spot-bellied eagle-owl, Oriental scops owl (Otus sunia), brown boobook (Ninox scutulata) and jungle owlet (Glaucidium radiatum) are known night birds in the region.[42]
A juvenile cinereous vulture(Aegypius monachus) was recorded in spring 2019.[43] The vulture populations in Moyar River valley were surveyed in March 2019. About 200 white-rumped vultures and about 30 active white-backed vulture(Gyps africanus) nests were observed; Indian vultures(G. indicus) and red-headed vultures(Sarcogyps calvus) were sighted at several locations.[44]
In 1992, six Indian star tortoises(Geochelone elegans) were sighted in scrubland at elevations of 850–950 m (2,790–3,120 ft).[46]
An ornate flying snake (Chrysopelea ornata) was observed in 2006.[47]
The mugger crocodile(Crocodylus palustris) population in Moyar River was thought to encompass about 100 individuals as of 2009.[48]
Small reptiles recorded in Mudumalai National Park comprise striped coral snake (Calliophis nigrescens), Elliot's forest lizard (Monilesaurus ellioti), Jerdon's day gecko(Cnemaspis jerdonii), Goan day gecko(C. indraneildasii) and Beddome's ground skink (Kaestlea beddomii).[49]
A dead Bibron's coral snake (Calliophis bibroni) was discovered on the road in the Theppakadu area at an elevation of 894 m (2,933 ft) in August 2013, the first record since 1874.[50]
A Bengal monitor(Varanus bengalensis) was recorded in 2018.[12]
The Indian rock python (Python molurus) was studied in the frame of a telemetry project in the Moyar River valley from 2017 to 2020. In February 2019, a 3.7 m (12 ft) long female Indian rock python was observed mating with two smaller males measuring 1.98 and 2.22 m (6 ft 6 in and 7 ft 3 in).[51]
From 1979 to 2011, remains of 148 dead Asian elephants were found in the park; 50 individuals were killed by poachers.[52]
Traffic on three public roads cutting through Mudumalai National Park pose a significant threat to the park's wildlife; between December 1998 and March 1999 alone, 180 animals belonging to 40 species were killed by drivers.[53] Between December 2006 and November 2007, 101 amphibians and 78 reptiles became roadkills on a 6 km (3.7 mi) stretch of the national highway passing through the park including Indirana frogs, Indian skipper frog (Euphlyctis cyanophlyctis), bronzed frog (Indosylvirana temporalis), pigmy wrinkled frog (Nyctibatrachus beddomii), Asian common toad (Duttaphrynus melanostictus), common green forest lizard (Calotes calotes), Blanford's rock agama(Psammophilus blanfordanus), Mysore day gecko(Cnemaspis mysoriensis), bronze grass skink (Eutropis macularia), green keelback (Rhabdophis plumbicolor), trinket snake(Coelognathus helena), Russell's viper(Daboia russelii), common krait(Bungarus caeruleus) and hump-nosed viper (Hypnale hypnale).[54] Between January 2014 and December 2016, 497 Indian palm squirrels(Funambulus palmarum) were found killed in traffic collisions on a 40 km (25 mi) long stretch of a state highway passing through the park.[55] A 0.913 m (2 ft 11.9 in) long roadkilled Bibron's coral snake was found in September 2016.[56]
Proliferating tourism resorts and increasing demand for firewood at the national park's periphery are also considered threats to its ecosystem.[48] In 1995, the annual firewood need was estimated at 376 kg (829 lb) per person living in the periphery of the national park.[57]
Between 1999 and 2013, six forest fires affected dry deciduous forest patches ranging in size from 80 ha (200 acres) to 85 km2 (33 sq mi) in the northern part of the national park; the plant diversity in burned patches needs more than 15 years to recover.[58]
