Mudumalai National Park is anational park in theNilgiri Mountains inTamil 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 theNilgiri District and shares boundaries with the states ofKarnataka andKerala. A part of this area has been protected since 1940. The national park has been part ofNilgiri Biosphere Reserve since 1986 and was declared atiger 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 harbourstropical and subtropical moist broadleaf forests with 498 plant species, at least 266 bird species, 18carnivore and 10herbivore species. It is drained by theMoyar River and several tributaries, which harbour 38fish species.
Traffic on three public roads passing through the national park has caused significantroadkills of mammals, reptiles and amphibians. The park's northern part has been affected by severalwildfires since 1999.
The word Mudumalai is aTamil word withமுது 'mutu' meaning old, ancient, original; andமுதுகாடு 'mudhukadu' meaning ancient forest.[1] The wordமலை 'malai' means hill or mountain.[2]The name 'Mudumalai forest' was already in use when the British Government rented the forest in 1857 forlogging purposes from the Raja ofNeelambur.[3]In 1914, large forest tracts on theSigur 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 intoNilgiri Biosphere Reserve in 1986.[4]It was declared as aTiger Reserve underProject 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 1,060cattle. In 2010, it was proposed to resettle them.[5] This notification was criticised by activists and conservationists as having been intransparent and undemocratic.[6]
In 2010, theNational Tiger Conservation Authority approved the release of funds to Mudumalai Tiger Reserve in the frame of Project Tiger.[7] In 2020, Project Tiger has been extended until 2021 with funding of₹ 114.1 million borne by theGovernment of India and theGovernment of Tamil Nadu.[8]

Mudumalai National Park covers 321 km2 (124 sq mi) in the eastern hills of theWestern Ghats at an elevation range of 850–1,250 m (2,790–4,100 ft); it is bordered in the west byWayanad Wildlife Sanctuary, in the north byBandipur National Park and in the east by SigurReserve Forest.[4] In the south, it is bordered by Singara Reserve Forest.[9] TheMoyar 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 surroundingbuffer zone of 367.59 km2 (141.93 sq mi) was designated as the Mudumalai Tiger Reserve.[11][12]
The elevation range of 250–1,200 m (820–3,940 ft) in the Western Ghats is characterised byevergreen forest withdipterocarp species prevailing.[13]Its undulating hills consist mostly ofhornblendite andbiotite gneiss with black sandyloam; red heavy loam prevails in the southern part.[14]It is part of theecoregionSouth Western Ghats moist deciduous forests.[15]Mudumalai National Park and the adjacent Sigur Reserve Forest form an importantwildlife corridor within the NilgiriBiosphere Reserve and provide the highestlandscape connectivity for theAsian elephant (Elephas maximus) population in the region.[16]
Mudumalai National Park receives about 1,420 mm (56 in) rainfall annually, most of it during thesouthwest 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]
Mudumalai National Park harbourstropical and subtropical moist broadleaf forests.[15] Thefloral diversity comprises 498 plant species including 154tree, 77shrub, 214herb and 53vine species.[18]Teak(Tectona grandis) and axlewood(Anogeissus latifolia) are the dominant tree species with a density of more than 105 trees/ha (42 trees/acre).[19]Prominent tree species include flame-of-the-forest(Butea monosperma), Indian laurel(Terminalia elliptica), kusum tree(Schleichera oleosa), weaver's beam tree(Schrebera swietenioides), Malabar kino tree(Pterocarpus marsupium), Indian rosewood(Dalbergia latifolia), Malabar plum(Syzygium cumini), silk-cotton tree(Bombax ceiba) and Indian beech(Millettia pinnata); moist deciduous forest is interspersed with giant thorny bamboo(Bambusa bambos). Mango(Mangifera indica) and persimmon(Diospyros) grow along river courses. Climbers include orange climber(Zanthoxylum asiaticum),Wattakaka volubilis, frangipani vine(Chonemorpha fragrans), trellis-vine(Pergularia daemia), purple morning glory(Argyreia cuneata), striped cucumber(Diplocyclos palmatus) and severaljasmine species.[14]Ceylon satinwood(Chloroxylon swietenia), red cedar(Erythroxylum monogynum) and catechu(Senegalia catechu) are the dominant plants inshrubland patches.[20]
Lantana camara is aninvasive species that negatively affects the dispersal of the native Indian gooseberry(Phyllanthus emblica) andKydia calycina, but does not affect growth and dispersal of other shrubs.[21] A study onnesting behaviour of birds revealed thatred-vented bulbul(Pycnonotus cafer) andred-whiskered bulbul(P. jocosus) prefer its top canopy level for building nests in spring.[22]
An exceptionally large arjun tree(Terminalia arjuna) with a height of 32 m (105 ft) and a girth of 8.45 m (27.7 ft) was detected in the Moyar River valley in 2019; it was used bywhite-rumped vulture(Gyps bengalensis),brown fish owl(Ketupa zeylonensis),spot-bellied eagle-owl(Bubo nipalensis),crested honey buzzard(Pernis ptilorhynchus),changeable hawk-eagle(Nisaetus cirrhatus) andshikra(Accipiter badius) for roosting.[23]
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]

A survey carried out between November 2008 and February 2009 revealed that about 29Indian leopards (Panthera pardus fusca) and 19Bengal 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) andleopard cat (P. bengalensis) were recorded duringcamera trap surveys in 2010–2011 and 2018.[26][12]Twodhole (Cuon alpinus) packs were monitored during 1989–1993 and hadhome 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), andNilgiri marten (Martes gwatkinsii) were also recorded in 2018.[12]
Scat ofsloth 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 andhoney bees.[28]Small Indian civet (Viverricula indica),Asian palm civet (Paradoxurus hermaphroditus) andbrown palm civet (P. jerdoni) live in both deciduous and semi-evergreen forest patches;ruddy mongoose (Urva smithii) lives foremost in deciduous forest, whereasstripe-necked mongoose (U. vitticollis) frequents riverine areas, andIndian grey mongooseU. edwardsii open habitats.[29] The mongooses forage foremost forpill millipedes,dung beetles, fruits, smallrodents, 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 largestmammal in the park with an estimated 536–1,001 individuals in 25 herds in 2000.[32] Herds comprise up to 22 individuals. Thegaur (Bos gaurus) is the largestungulate in the park, with herds of up to 42 individuals that frequent foremost grasslands in the vicinity of water sources.[33]Thesambar 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. Thechital (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) andIndian 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 primaryseed dispersers in the park.[35] Present are alsofour-horned antelope (Tetracerus quadricornis),blackbuck (Antilope cervicapra),wild boar (Sus scrofa),Indian pangolin (Manis crassicaudata) andIndian crested porcupine (Hystrix indica).[12]
Fourbonnet macaque (Macaca radiata) troops were studied in 1997, which ranged in size from 28 to 35 members and lived insympatry withgray langur (Semnopithecus entellus) troops.[36]A troop in the Moyar River valley foraged on leaves, flowers and fruits of several tree and shrub species includingtamarind (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 andgrasshoppers.[37]The range of theIndian 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 contiguouscanopy. 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 andGrewia tiliifolia.[38]TheIndian 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, apainted bat (Kerivoula picta) was sighted in the eastern part of the tiger reserve.[40]

In 1992, sixIndian 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]Themugger crocodile(Crocodylus palustris) population in Moyar River was thought to encompass about 100 individuals as of 2009.[48]Smallreptiles 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 theTheppakadu area at an elevation of 894 m (2,933 ft) in August 2013, the first record since 1874.[50]ABengal monitor(Varanus bengalensis) was recorded in 2018.[12]The Indian rock python (Python molurus) was studied in the frame of atelemetry 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 observedmating with two smaller males measuring 1.98 and 2.22 m (6 ft 6 in and 7 ft 3 in).[51]
The Moyar River and tributaries harbour 38 fish species, including Nilgiri mystus(Hemibagrus punctatus),Puntius mudumalaiensis,Puntius melanostigma,reba carp(Cirrhinus reba),common carp(Cyprinus carpio), Deccan mahseer(Tor khudree), Malabar baril(Barilius gatensis), mullya garra(Garra mullya),zig-zag eel(Mastacembelus armatus) and bullseye snakehead(Channa marulius).[10]
From 1979 to 2011, remains of 148 dead Asian elephants were found in the park; 50 individuals were killed bypoachers.[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 becameroadkills on a 6 km (3.7 mi) stretch of the national highway passing through the park includingIndirana 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, 497Indian 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 forfirewood 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]
