The '''Western Ghats''', also known as the '''Sahyadri''', is a mountain range that stretches {{cvt|1,600|km|mi}} along the [[West Coast of India|western coast]] of the [[Indian peninsula]]. Covering an area of {{cvt|160,000|km2|mi2}}, it traverses the [[states and union territories of India|Indian states]] of [[Gujarat]], [[Maharashtra]], [[Goa]], [[Karnataka]], [[Kerala]], and [[Tamil Nadu]]. The range forms an almost continuous chain of mountains along the western edge of the [[Deccan Plateau]], from the [[Tapti River]] to [[Swamithoppe]] in [[Kanyakumari district]] at the southern tip of the Indian peninsula. The Western Ghats meet with the [[Eastern Ghats]] at [[Nilgiris]] before continuing south.


The '''Western Ghats''' or the '''Sahyadri Mountain range''' is a mountain range that covers an area of {{cvt|160,000|km2|mi2}} in a stretch of {{cvt|1,600|km|mi}} parallel to the western coast of the [[Indian peninsula]], traversing the [[states and union territories of India|states]] of [[Karnataka]], [[Goa]], [[Maharashtra]], [[Gujarat]], [[Kerala]], and [[Tamil Nadu]].<ref name="auto">{{cite web|title=Western Ghats|url=https://whc.unesco.org/en/list/1342}}</ref> It is a [[UNESCO]] [[World Heritage Site]] and is one of the eight [[biodiversity hotspot]]s in the world.<ref>{{cite journal |title=Biodiversity hotspots for conservation priorities |journal=Nature|volume=403|issue=6772|pages=853–858 |doi=10.1038/35002501 |pmid=10706275 |year=2000 |last1=Myers|first1=N. |last2=Mittermeier|first2=R.A. |last3=Mittermeier|first3=C.G. |last4=Da Fonseca|first4=G.A.B. |last5=Kent|first5=J. |bibcode=2000Natur.403..853M|s2cid=4414279}}</ref> It is sometimes called the [[Great Escarpment of India]].<ref>{{cite book|last=Migon|first=P. |title=Geomorphological Landscapes of the World |date=2010 |publisher=Springer|isbn=978-90-481-3054-2|page=257}}</ref> It contains a very large proportion of the country's [[flora]] and [[fauna]], many of which are endemic to these region.<ref>{{cite web |title=A biodiversity hotspot|url=http://wwf.panda.org/knowledge_hub/where_we_work/western_ghats/}}</ref> According to [[UNESCO]], the Western Ghats are older than the [[Himalayas]].

Geologic evidence indicates that the mountains were formed during the break-up of the supercontinent of [[Gondwana]]. The mountains arose along the west coast of India somewhere in the [[late Jurassic]] and [[early Cretaceous]] periods when India separated from the [[Africa]]n continent. The mountains can be roughly divided into three parts: the northern section with an elevation ranging from {{cvt|900-1500|m}}, the middle section starting south of Goa with a lower elevation of less than {{cvt|900|m}}, and the southern section where the altitude rises again. The Western Ghats have several peaks that rise above {{cvt|2,000|m}}, with [[Anamudi]] ({{cvt|2695|m|ft}}) being the highest peak. The average elevation is around {{cvt|1200|m}}.


The range starts near south of the [[Tapti river]] and runs approximately {{cvt|1600|km}} through the states of Maharashtra, Karnataka, Goa, Kerala and Tamil Nadu ending at [[Marunthuvazh Malai]] near the southern tip of India. These hills cover {{cvt|160000|km2}} and form the catchment area for complex riverine [[Drainage system (geomorphology)|drainage systems]] that drain almost 40% of India. The Western Ghats block the [[southwest monsoon]] winds from reaching the Deccan Plateau.{{citation needed|date=March 2020}} The average elevation is around {{cvt|1200|m}}.<ref name="APMN">{{cite web |url=http://apmn.icimod.org/mountains/ch2_peninsula.php |title= The Peninsula|access-date=19 March 2007 |work=Asia-Pacific Mountain Network |archive-url = https://web.archive.org/web/20070812064356/http://apmn.icimod.org/mountains/ch2_peninsula.php|archive-date=12 August 2007}}</ref>
The Western Ghats form one of the major [[Drainage basin|watersheds]] of India, feeding many perennial river systems that drain almost 40% of the land area of the country. Because of the higher elevation of the Deccan Plateau on the west, most rivers flow eastwards towards the [[Bay of Bengal]], resulting in chiselled eastern slopes and steeper western slopes facing the [[Arabian Sea]]. The Western Ghats play an important role in determining the climate and seasons in India. It blocks the rain-bearing [[monsoon]] winds flowing eastward from the Arabian Sea, resulting in rainfall along the western coast. By the time the air rises above the mountains it is dry, forming a [[rain shadow]] region with very little rainfall on the [[leeward]] side towards the interior of the Deccan Plateau.


The area is one of the world's ten "hottest [[biodiversity hotspot]]s." It has over 7,402 species of flowering plants, 1,814 species of non-flowering plants, 139 mammal species, 508 bird species, 227 reptile species, 179 amphibian species, 290 freshwater fish species, and 6,000 insect species. It is likely that many undiscovered species live in the Western Ghats. At least 325 globally [[threatened species]] occur in the Western Ghats.<ref name="Flowering plants">{{cite book |last1=Nayar |first1=T.S. |last2=Rasiya Beegam |first2=A. |last3=Sibi |first3=M. |title=Flowering Plants of the Western Ghats, India (2 Volumes) |date=2014 |publisher=Jawaharlal Nehru Tropical Botanic Garden and Research Institute |location=Thiruvananthapuram, India}}</ref><ref>{{cite journal |last1=Myers |first1=N. |last2=Mittermeier |first2=R.A. |last3=Mittermeier |first3=C.G. |last4=Fonseca |first4=G.A.B.Da |last5=Kent |first5=J. |year=2000 |title=Biodiversity Hotspots for Conservation Priorities |journal=Nature |volume=403 |issue=6772 |pages=853–858 |doi=10.1038/35002501 |pmid=10706275|bibcode=2000Natur.403..853M |s2cid=4414279}}</ref><ref name="Neelesh Fish">{{cite journal |last1=Dahanukar |first1=N. |last2=Raut |first2=R. |last3=Bhat |first3=A. |year=2004 |title=Distribution, endemism and threat status of freshwater fishes in the Western Ghats of India |journal=Journal of Biogeography |volume=31 |issue=1 |pages=123–136 |doi=10.1046/j.0305-0270.2003.01016.x |s2cid=83574801 |url=https://semanticscholar.org/paper/5c915245a382eabc0650d1e37492c57e6c59e70e}}</ref>
The Western Ghats region is a [[biodiversity hotspot]]. It contains a large number of different species of flora and fauna, most of which are endemic to this region. At least 325 globally [[threatened species]] occur in the Western Ghats. The region was declared a [[UNESCO]] [[World Heritage Site]] in 2012.


==Etymology==
== Etymology ==
The word [[Ghat]] is explained by numerous [[Dravidian languages|Dravidian]] etymons such as the [[Tamil language|Tamil]] ''gattu'' (hill and hill forest), [[Kannada language|Kannada]] ''gaati'' and ''ghatta'' (mountain range), [[Tulu language|Tulu]] ''gatta'' (hill or hillside), and ''ghattam'' in [[Malayalam language|Malayalam]] (mountainous way, riverside and hairpin bends).<ref>{{cite book|last=Jaini|first=Padmanabh S.|title=Jainism and Early Buddhism|year=2003|publisher=Jain Publishing Company|pages=523–538|url=https://books.google.com/books?id=5_EdL2FtIqQC&q=etymology+dravidian|isbn=9780895819567}}</ref>
The name Western Ghats derives from the word [[ghat]] and the cardinal direction in which it is located with respect to the Indian mainland. ''Ghat'', a term used in the [[Indian subcontinent]], depending on the context, could either refer to a [[Geography of India#Coastal plains and ghats|range of stepped hills]] such as the [[Eastern Ghats]] and Western Ghats, or a series of steps leading down to a body of water or [[wharf]].<ref>{{cite book|author1=Sunithi L.

The Western Ghats extend from the [[Satpura Range]] in the north, stretching from [[Gujarat]] to [[Tamil Nadu]].<ref>{{cite web|url=https://whc.unesco.org/en/list/1342|title=Western Ghats – UNESCO World Heritage Centre}}</ref> It traverses south through the states of [[Maharashtra]], [[Goa]], [[Karnataka]] and [[Kerala]]. Major gaps in the range are the [[Goa Gap]], between the Maharashtra and Karnataka sections, and the [[Palghat Gap]] on the Tamil Nadu and Kerala border between the [[Nilgiri Mountains]] and the [[Anaimalai Hills]]. The mountains intercept the rain-bearing westerly [[monsoon]] winds, and are consequently an area of high rainfall, particularly on their western side. The dense forests also contribute to the precipitation of the area by acting as a substrate for condensation of moist rising [[orographic]] winds from the sea, and releasing much of the moisture back into the air via [[transpiration]], allowing it to later condense and fall again as rain.{{citation needed|date=February 2022}}

The Western Ghats form one of the four [[Drainage basin|watersheds]] of India, feeding the perennial rivers of India. The major river systems originating in the Western Ghats are the [[Godavari river|Godavari]], [[Kaveri river|Kaveri]], [[Krishna river|Krishna]], [[Thamiraparani]] and [[Tungabhadra]] rivers. The majority of streams draining the Western Ghats join these rivers, and carry a large volume of water during the monsoon months. These rivers flow to the east due to the gradient of the land and drain out into the [[Bay of Bengal]]. Major tributaries include the [[Bhadra river|Bhadra]], [[Bhavani river|Bhavani]], [[Bhima River|Bhima]], [[Malaprabha River|Malaprabha]], [[Ghataprabha River|Ghataprabha]], [[Hemavathi river|Hemavathi]] and [[Kabini River|Kabini]] rivers. The [[Periyar River|Periyar]], [[Bharathappuzha]], [[Pamba River|Pamba]], [[Netravati River|Netravati]], [[Sharavathi]], [[Kali River (Karnataka)|Kali]], [[Mandovi]] and [[Zuari River|Zuari]] rivers flow westwards towards the Western Ghats, draining into the [[Arabian Sea]], and are fast-moving, owing to the steeper gradient. The rivers have been dammed for [[hydroelectric]] and [[irrigation]] purposes with major reservoirs spread across the states. The Western Ghats account for 80% of India's hydropower generation. The reservoirs are important for their commercial and sport fisheries of [[rainbow trout]], [[mahseer]] and [[common carp]].<ref name=SehgalFish>{{cite web|url=http://www.fao.org/docrep/003/x2614e/x2614e06.htm|last=Sehgal|first=K.

The Western Ghats play an important role in determining the climate and seasons in India. During the dry summer months of April{{snd}}May, heat builds up on the land, which draws air from the sea. The air, which picks up moisture along the way and flows eastward from the Arabian Sea, is blocked by the Western Ghats.<ref>{{cite web|url=https://www.britannica.com/science/Indian-monsoon|title=Indian monsoon|publisher=Britannica|access-date=1 December 2023|archive-date=1 August 2016|archive-url=https://web.archive.org/web/20160801140005/https://www.britannica.com/science/Indian-monsoon|url-status=live}}</ref> The rising air cools and brings about [[orographic precipitation]] along the western coast.<ref>{{cite web|url=https://www.britannica.com/science/orographic-precipitation|title=Orographic precipitation|publisher=Britannica|access-date=1 December 2023|archive-date=5 January 2020|archive-url=https://web.archive.org/web/20200105212629/https://www.britannica.com/science/orographic-precipitation|url-status=live}}</ref> This signifies the onset of the [[monsoon]] season in June. By the time the air rises above the mountains, it becomes dry, resulting in a [[rain shadow]] region with very little rainfall on the [[leeward]] side towards the interior of the Deccan plateau. The monsoon winds rounding up the peninsula and moving from the east from the [[Bay of Bengal]] pass over the Eastern Ghats and bring the majority of the rainfall to the plains up north.<ref>{{cite web|url=https://wgbis.ces.iisc.ac.in/biodiversity/sahyadri/wgbis_info/climate.htm|title=Climate of Western Ghats|publisher=Indian Institute of Science|access-date=1 December 2023|archive-date=21 May 2024|archive-url=https://web.archive.org/web/20240521124321/https://wgbis.ces.iisc.ac.in/biodiversity/sahyadri/wgbis_info/climate.htm|url-status=live}}</ref>


==Climate==
Climate in the mountains shows variations with altitude across the range. Due to its physical proximity to the [[equator]] and the Arabian Sea, the region experiences a warm and humid [[tropical climate]] throughout the year. Mean temperatures range from {{cvt|20|°C}} in the south to {{cvt|24|°C}} in the north. Subtropical or temperate climates, and occasional near-zero temperatures during winter are experienced in regions with higher elevations. The coldest period in the region are the wettest monsoon period in the southern part of the mountain range.<ref name="WII">{{cite book|url=https://archive.org/details/ConservationOfRainforestsInIndia/mode/2up|title=Conservation of Rain forests in India|chapter=Biodiversity of the Western Ghats - An Overview|author=R.J. Ranjit Daniels|access-date=1 December 2023|publisher=Wildlife Institute of India}}</ref> Annual rainfall in this region averages {{cvt|100|cm}} to {{cvt|900|cm}}, with an average rainfall of {{cvt|250|cm}}. The total amount of rain does not depend on the spread of the area; areas in northern Maharashtra receive heavy rainfall followed by long dry spells, while regions closer to the equator receive lower annual rainfall and have rain spells lasting several months in a year.<ref name="WII"/>

The area including [[Agumbe]], [[Hulikal]] and [[Amagaon]] in [[Karnataka]], Mahabaleshwar and Tamhini in [[Maharashtra]] are often referred to as the "[[Cherrapunji]] of southwest India" or the "rain capital of southwest India". [[Kollur, Udupi district|Kollur in Udupi district]], Kokkali and [[Nilkund]] in [[Sirsi, Karnataka|Sirsi]], [[Samse]] in [[Mudigere]] of [[Karnataka]], and [[Neriamangalam]] in the [[Ernakulam district]] of [[Kerala]] are the wettest places in the Western Ghats. Heavy precipitation does occur in the surrounding regions due to the long continuity of the mountains without passes and gaps. Changes in the direction and pace of the wind do affect the average rainfall and the wettest places might vary. However, [[Maharashtra]] and the northern part of Western Ghats in [[Karnataka]] on average receive heavier rainfall than [[Kerala]] and the southern part of Western Ghats in Karnataka.


The climate in the Western Ghats varies with altitudinal gradation and distance from the equator. The climate is humid and tropical in the lower reaches tempered by the proximity to the sea. Elevations of {{convert|1500|m|ft|0|abbr=on}} and above in the north and {{convert|2000|m|ft|0|abbr=on}} and above in the south have a more temperate climate. The average annual temperature is around {{convert|15|°C}}. In some parts frost is common, and temperatures reach the freezing point during the winter months. Mean temperatures range from {{convert|20|°C}} in the south to {{convert|24|°C}} in the north. It has also been observed that the coldest periods in the South Western Ghats coincide with the wettest.<ref name="WII">{{cite web|url=http://www.wii.gov.in/envis/rain_forest/chapter2.htm|first=R.J.|last=Ranjit Daniels|title=Biodiversity of the Western Ghats – An Overview|access-date=19 March 2007|work=Wildlife Institute of India|url-status=dead|archive-url=https://archive.today/20070228195706/http://www.wii.gov.in/envis/rain_forest/chapter2.htm|archive-date=28 February 2007}}</ref>

During the [[monsoon|monsoon season]] between June and September, the unbroken Western Ghats chain acts as a barrier to the moisture-laden clouds. The heavy, eastward-moving rain-bearing clouds are forced to rise and in the process deposit most of their rain on the windward side. Rainfall in this region averages {{convert|300|cm}} to {{convert|400|cm}} with localised extremes reaching {{convert|900|cm}}. The eastern regions of the Western Ghats, which lie in the [[rain shadow]], receive far less rainfall (about {{convert|100|cm}}), resulting in an average rainfall of {{convert|250|cm}} across all regions. The total amount of rain does not depend on the spread of the area; areas in northern Maharashtra receive heavy rainfall followed by long dry spells, while regions closer to the equator receive lower annual rainfall and have rain spells lasting several months in a year.<ref name="WII"/>
=== Flora ===
 
The Western Ghats consist of four [[tropical and subtropical moist broadleaf forest|tropical and subtropical moist broadleaf]] terrestrial [[ecoregions]] of the [[Indomalayan]] [[Biogeographic realm|realm]], with the northern portion of the range generally drier than the southern portion.<ref>{{cite web|url=https://www.worldwildlife.org/biomes/tropical-and-subtropical-moist-broadleaf-forests|title=Tropical and subtropical moist broadleaf forest|publisher=WWF|access-date=1 December 2023|archive-date=21 May 2024|archive-url=https://web.archive.org/web/20240521124905/https://www.worldwildlife.org/biomes/tropical-and-subtropical-moist-broadleaf-forests|url-status=live}}</ref> These include the following:

[[File:Shola.jpg|thumb|[[Sholas]], a unique type of stunted tropical montane forest found in the valleys]]
The Karnataka region on average receives heavier rainfall than the Kerala, Maharashtra and Goa regions. Meanwhile, the Ghats in Karnataka have fewer passes and gaps and therefore the western slopes of Karnataka receive heavy rainfall, over 400&nbsp;cm more than other regional parts of the Western Ghats.

The Western Ghats are home to four [[tropical and subtropical moist broadleaf forest]] [[ecoregions]] – the [[North Western Ghats moist deciduous forests]], [[North Western Ghats montane rain forests]], [[South Western Ghats moist deciduous forests]], and [[South Western Ghats montane rain forests]]. The northern portion of the range is generally drier than the southern portion, and at lower elevations makes up the North Western Ghats moist deciduous forests ecoregion, with mostly deciduous forests made up predominantly of [[teak]]. Above 1,000 meters elevation are the cooler and wetter [[North Western Ghats montane rain forests]], whose evergreen forests are characterised by trees of the family ''[[Lauraceae]]''.{{citation needed|date=February 2022}}


The evergreen forests in [[Wayanad]] mark the transition zone between the northern and southern ecoregions of the Western Ghats. The southern ecoregions are generally wetter and more species-rich. At lower elevations are the [[South Western Ghats moist deciduous forests]], with ''[[Cullenia]]'' the characteristic tree genus, accompanied by teak, [[dipterocarp]]s, and other trees. The moist forests transition to the drier [[South Deccan Plateau dry deciduous forests]], which lie in its rain shadow to the east. Above 1,000 meters are the [[South Western Ghats montane rain forests]], also cooler and wetter than the surrounding lowland forests, and dominated by evergreen trees, although some [[montane grassland]]s and stunted forests can be found at the highest elevations. The South Western Ghats montane rain forests are the most species-rich ecoregion in peninsular [[India]]; eighty percent of the [[flowering plant]] species of the entire Western Ghats range are found in this ecoregion.{{citation needed|date=February 2022}}

[[File:The Western Ghat from Kannavam Forest.jpg|thumb|Dense rainforests cover the Western Ghats.]]
Historically the Western Ghats were covered in dense forests that provided wild foods and natural habitats for native [[Indigenous peoples|tribal people]]. Its inaccessibility made it difficult for people from the [[Deccan Plateau|plains]] to cultivate the land and build settlements. After the establishment of [[British Empire|British colonial rule]] in the region, large swathes of territory were cleared for agricultural plantations and timber. The forest in the Western Ghats has been severely fragmented due to human activities, especially [[clear-felling]] for tea, coffee, and teak plantations<ref>{{Cite web|url=https://travel.manoramaonline.com/travel/beyond-kerala/2019/06/11/camp-worlds-highest-tea-estate-kolukkumalai-munnat-drive.html|title=Camp at world's highest tea estate Kolukkumalai|website=OnManorama|language=en|access-date=2019-06-12}}</ref> from 1860 to 1950.  Species that are rare, [[Endemism|endemic]] and habitat specialists are more adversely affected and tend to be lost faster than other species.

The area is ecologically sensitive to development and was declared an ecological hotspot in 1988 through the efforts of ecologist [[Norman Myers]]. The area covers five percent of India's land; 27% of all species of higher plants in India (4,000 of 15,000 species) are found here and 1,800 of these are endemic to the region. The range is home to at least 84 amphibian species, 16 bird species, seven mammals, and 1,600 flowering plants which are not found elsewhere in the world. The [[Government of India]] has established many [[protected areas of India|protected areas]] including 2 [[Biosphere reserves of India|biosphere reserves]], 13 [[national parks of India|national parks]] to restrict human access, several [[Wildlife sanctuaries of India|wildlife sanctuaries]] to protect specific endangered species and many [[Reserved forests and protected forests of India|reserve forests]], which are all managed by the forest departments of their respective state to preserve some of the ecoregions still undeveloped. The [[Nilgiri Biosphere Reserve]], comprising {{convert|5500|km2}} of the evergreen forests of [[Nagarahole]] and deciduous forests of [[Bandipur National Park|Bandipur]] in Karnataka, adjoining regions of [[Wayanad]]-[[Mukurthi National Park|Mukurthi]] in Kerala and [[Mudumalai National Park]]-[[Sathyamangalam Wildlife Sanctuary|Sathyamangalam]] in Tamil Nadu, forms the largest contiguous protected area in the Western Ghats.<ref>{{cite web |url=http://cpreec.org/04_phamplets/08_nilgiri_bio_reser/nilgiri_bio_reser.html|title= The Nilgiri Bio-sphere Reserve|archive-url=https://web.archive.org/web/20060928151229/http://www.cpreec.org/04_phamplets/08_nilgiri_bio_reser/nilgiri_bio_reser.html |archive-date=28 September 2006}}</ref> [[Silent Valley National Park|Silent Valley]] in Kerala is among the last tracts of virgin tropical evergreen forest in India.<ref name="wg">{{cite news|url=http://www.thehindu.com/news/national/kerala/article52465.ece|title=No clearance for mining, hydel projects that destroy Western Ghat|last=Ramesh|date=21 November 2009|newspaper=[[The Hindu]]|publisher=Kasturi & Sons Ltd.|access-date=29 December 2009|location=Palakkad}}</ref><ref>{{cite news|url=http://www.hindu.com/2009/08/04/stories/2009080456210300.htm|archive-url=https://web.archive.org/web/20090808123705/http://www.hindu.com/2009/08/04/stories/2009080456210300.htm|url-status=dead|archive-date=8 August 2009|title=Gundia project has not got Centre's nod|last=staff|access-date=29 December 2009|location=Chennai, India|work=[[The Hindu]]|date=4 August 2009}}</ref>

===Amphibians===
Historically, the Western Ghats were covered in dense forests, which formed the natural habitat for wildlife along with the native [[Indigenous peoples|tribal people]]. Its inaccessibility made it difficult for people from the [[Deccan Plateau|plains]] to cultivate the land and build settlements.

[[File:Bandipur fires 2019.jpg|thumb|Forest fires 2019]]
The Western Ghats face a lot of issues. Poaching, Deforestation, Forest fires, Invasion of alien species and Dangers to native tribes are the main threats. Despite the 1972 Indian law of that banned poaching, people still tend to illegally hunt down animals such as tigers, elephants and chital for skin, fur or tusks. Forests here are being destroyed for farming or livestock. Animals that eat livestock are also being killed by farmers. Forest fires take place annually during the dry summer season, especially in the Nagarhole-Bandipur-Wayanad-Mudumalai-Satyamangalam-BRT block which has the most biodiverse locations in the Western Ghats with the largest populations of tigers and elephants residing there.
 
Native tribes of the Western Ghats are being evicted from their homelands. This results in degradation of the tribal culture. The rich biodiversity in both flora and fauna have made the Western Ghats a target for many corporate companies to gain resources. This however is checked by the Government of India and the State Governments to protect the Western Ghats.

The Western Ghats, also known as the Sahyadri, is a mountain range that stretches 1,600 km (990 mi) along the western coast of the Indian peninsula. Covering an area of 160,000 km2 (62,000 sq mi), it traverses the Indian states of Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Tamil Nadu. The range forms an almost continuous chain of mountains along the western edge of the Deccan Plateau, from the Tapti River to Swamithoppe in Kanyakumari district at the southern tip of the Indian peninsula. The Western Ghats meet with the Eastern Ghats at Nilgiris before continuing south.

Geologic evidence indicates that the mountains were formed during the break-up of the supercontinent of Gondwana. The mountains arose along the west coast of India somewhere in the late Jurassic and early Cretaceous periods when India separated from the African continent. The mountains can be roughly divided into three parts: the northern section with an elevation ranging from 900–1,500 m (3,000–4,900 ft), the middle section starting south of Goa with a lower elevation of less than 900 m (3,000 ft), and the southern section where the altitude rises again. The Western Ghats have several peaks that rise above 2,000 m (6,600 ft), with Anamudi (2,695 m (8,842 ft)) being the highest peak. The average elevation is around 1,200 m (3,900 ft).

The Western Ghats form one of the major watersheds of India, feeding many perennial river systems that drain almost 40% of the land area of the country. Because of the higher elevation of the Deccan Plateau on the west, most rivers flow eastwards towards the Bay of Bengal, resulting in chiselled eastern slopes and steeper western slopes facing the Arabian Sea. The Western Ghats play an important role in determining the climate and seasons in India. It blocks the rain-bearing monsoon winds flowing eastward from the Arabian Sea, resulting in rainfall along the western coast. By the time the air rises above the mountains it is dry, forming a rain shadow region with very little rainfall on the leeward side towards the interior of the Deccan Plateau.

The Western Ghats region is a biodiversity hotspot. It contains a large number of different species of flora and fauna, most of which are endemic to this region. At least 325 globally threatened species occur in the Western Ghats. The region was declared a UNESCO World Heritage Site in 2012.

Etymology[edit | edit source]

The name Western Ghats derives from the word ghat and the cardinal direction in which it is located with respect to the Indian mainland. Ghat, a term used in the Indian subcontinent, depending on the context, could either refer to a range of stepped hills such as the Eastern Ghats and Western Ghats, or a series of steps leading down to a body of water or wharf.[1][2] As per linguist Thomas Burrow, the word Ghat was derived from similar words used in various Dravidian languages such as kattu (mountain side, ridge, or dam) in Tamil, katte (dam), gatta (mountain), and gattu (bank or shore) in Kannada, and katta (dam), and gatte (shore or embankment) in Telugu.[3] The mountain range is also known as Sahyadri, derived from Sanskrit, meaning benevolent or tolerant mountain.[4]

Geology[edit | edit source]

The Western Ghats are the mountainous faulted, and eroded edge of the Deccan Plateau. Geologic evidence indicates that they were formed during the break-up of the super-continent of Gondwana. After the break-up, the Deccan Plateau was formed by basalt rocks, which caused the western side to rise at an elevation.[5]

Geophysical evidence indicates that the mountains arose along the west coast of India somewhere in the late Jurassic and early Cretaceous periods when India separated from the African continent.[6] Several faults triggered the formation of Western Ghats, then interspersed with valleys and river gorges. Because of the elevation of the Deccan Plateau on the west, most rivers flow from west to east, resulting in chiselled eastern slopes and steeper western slopes facing the sea.[6]

Geography[edit | edit source]

The Western Ghats form a continuous chain of mountains.

The Western Ghats extend from the Satpura Range south of the Tapti River in the north and runs approximately 1,600 km (990 mi) to the southern tip of the Indian peninsula, where it ends at the Marunthuvazh Malai at Swamithoppe in Kanyakumari district.[7][8] It covers an area of 160,000 km2 (62,000 sq mi), traversing the Indian states of Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Tamil Nadu.[9]

Topography[edit | edit source]

Mountain ranges of India, including the Western Ghats

The Western Ghats form an almost continuous chain of mountains running parallel to the western coast of India along the Arabian Sea.[10] The average elevation is around 1,200 m (3,900 ft).[11] There are three gaps in the mountain range: the northernmost Goa Gap, formed 65–80 million years ago (Mya), the oldest and widest Palghat Gap, formed 500 Mya, and the southernmost, narrowest Shencottah Gap.[12] The narrow coastal plain between the Western Ghats and the Arabian Sea is known as the Western Coastal Plains.[13]

The mountains can be roughly divided into three parts: the northern section with an elevation ranging from 900–1,500 m (3,000–4,900 ft), the middle section starting from the south of Goa with a lower elevation of less than 900 m (3,000 ft), and the southern section where the altitude rises again.[10] The Western Ghats meet with the Eastern Ghats in the Moyar River valley in the Nilgiris before continuing south.[14][15] The Western Ghats have many peaks that rise above 2,000 m (6,600 ft), with Anamudi (2,695 m (8,842 ft)) being the highest peak.[16]

Hydrography[edit | edit source]

The Western Ghats form one of the major watersheds of India, feeding many perennial rivers. These major river systems drain almost 40% of the land area of the country.[17] The major river systems originating in the Western Ghats are the Godavari, Kaveri, and Krishna.[10][18] Most rivers flow eastwards towards the Bay of Bengal owing to the steeper gradient moving from east to west, and many smaller streams drain the region, often carrying a large volume of water during the monsoon months.[17] The streams and rivers give rise to numerous waterfalls in the region.[19] The rivers have been dammed for hydroelectric and irrigation purposes, with major reservoirs spread across the region.[20][21]

Climate[edit | edit source]

Annual rainfall

The Western Ghats play an important role in determining the climate and seasons in India. During the dry summer months of April – May, heat builds up on the land, which draws air from the sea. The air, which picks up moisture along the way and flows eastward from the Arabian Sea, is blocked by the Western Ghats.[22] The rising air cools and brings about orographic precipitation along the western coast.[23] This signifies the onset of the monsoon season in June. By the time the air rises above the mountains, it becomes dry, resulting in a rain shadow region with very little rainfall on the leeward side towards the interior of the Deccan plateau. The monsoon winds rounding up the peninsula and moving from the east from the Bay of Bengal pass over the Eastern Ghats and bring the majority of the rainfall to the plains up north.[24]

Climate in the mountains shows variations with altitude across the range. Due to its physical proximity to the equator and the Arabian Sea, the region experiences a warm and humid tropical climate throughout the year. Mean temperatures range from 20 °C (68 °F) in the south to 24 °C (75 °F) in the north. Subtropical or temperate climates, and occasional near-zero temperatures during winter are experienced in regions with higher elevations. The coldest period in the region are the wettest monsoon period in the southern part of the mountain range.[25] Annual rainfall in this region averages 100 cm (39 in) to 900 cm (350 in), with an average rainfall of 250 cm (98 in). The total amount of rain does not depend on the spread of the area; areas in northern Maharashtra receive heavy rainfall followed by long dry spells, while regions closer to the equator receive lower annual rainfall and have rain spells lasting several months in a year.[25]

Biodiversity[edit | edit source]

The Western Ghats region is a biodiversity hotspot.[26][27] It consists of nearly 30% of all the species of flora and fauna found in India, most of which are endemic to this region.[28][29] At least 325 globally threatened species occur in the Western Ghats.[9]

Flora[edit | edit source]

The Western Ghats consist of four tropical and subtropical moist broadleaf terrestrial ecoregions of the Indomalayan realm, with the northern portion of the range generally drier than the southern portion.[30] These include the following:

Sholas, a unique type of stunted tropical montane forest found in the valleys
Terrestrial ecoregions of Western Ghats
Region Area Areas covered
North Western Ghats montane rain forests[31] 11,900 sq mi (31,000 km2) Goa, Karnataka, Maharashtra, Tamil Nadu
South Western Ghats montane rain forests[32] 8,700 sq mi (23,000 km2) Kerala, Tamil Nadu
North Western Ghats moist deciduous forests[33] 4,831 sq mi (12,510 km2) Gujarat, Karnataka, Maharashtra
South Western Ghats moist deciduous forests[34] 2,382 sq mi (6,170 km2) Karnataka, Kerala, Tamil Nadu

Other types of ecosystems include dry deciduous forests on the leeward rain shadow region, scrub forests at the foothills, peat bogs, and swamps.[35] Montane grasslands are found in high altitude locations in the south Western Ghats interspersed with sholas, a unique type of stunted tropical montane forest found in the valleys between the mountains.[36]

Earlier sources indicated about four to five thousand vascular plant species of which nearly one-third was endemic to the region.[37] Later studies and publications have recorded 7,402 species of flowering plants occurring in the Western Ghats of which 5,588 were described as indigenous, 376 are naturalized exotics, and 1,438 species are cultivated or planted.[38] Among the indigenous species, 2,253 species are endemic to India and of them, 1,273 species are exclusively confined to the Western Ghats. 645 tree species were recorded with a high endemic ratio of 56%. There are 850 to 1,000 species of bryophytes, including 682 species of mosses (28% endemic) and 280 species of liverworts (43% endemic), 277 species of pteridophytes and 949 species of lichens (26.7% endemic).[39]

Fauna[edit | edit source]

The Western Ghats are home to thousands of species of fauna, including at least 325 globally threatened species.[40] As per a 2010 report, following is the distribution of faunal species in the Western Ghats apart from more than 6,000 insect species.[35][41]

Fauna of Western Ghats (2010)
Taxonomic group Species Endemic % Endemic Endangered
Mammals 120 14 12% 31
Birds 508 19 4% 15
Amphibians 121 94 78% 43
Reptiles 156 97 62% 5
Fishes 218 116 53% 1

The Western Ghats region has one of the highest tiger populations, estimated at 985 in 2022.[42] The Western Ghats ecoregion has the largest Indian elephant population in the wild, with an estimated 11,000 individuals across eight distinct populations.[43][44] Other mammals include endangered and vulnerable species such as the lion-tailed macaque, Nilgiri tahr, leopard, Nilgiri langur, dhole, and gaur.[45][46][47] The endemic Nilgiri tahr, which was on the brink of extinction, has recovered and had an estimated 3,122 individuals in 2015.[48][49] Smaller endemic species include the Malabar large-spotted civet, Nilgiri marten, brown palm civet, stripe-necked mongoose, Indian brown mongoose, small Indian civet, and leopard cat.[50][51]

Bicolored frog is endemic to the region[52]

There are at least 19 species of birds endemic to the Western Ghats, including the endangered rufous-breasted laughingthrush, the vulnerable Nilgiri wood-pigeon, white-bellied shortwing, and broad-tailed grassbird, the near threatened grey-breasted laughingthrush, black-and-rufous flycatcher, Nilgiri flycatcher, and Nilgiri pipit, and the least concern Malabar (blue-winged) parakeet, Malabar grey hornbill, white-bellied treepie, grey-headed bulbul, rufous babbler, Wayanad laughingthrush, white-bellied blue-flycatcher, and the crimson-backed sunbird.[53]

As per a 2014 report, at least 227 species of reptiles are found in the Western Ghats.[54] The major population of the snake family Uropeltidae is restricted to the region.[55] Several endemic reptile genera and species occur here, with the region having a significant population of mugger crocodiles.[56] The amphibians of the Western Ghats are diverse and unique, with a high proportion of species being endemic to the tropical rainforests of India.[57] New frog species have continued to be discovered in the 21st century.[58] Frogs of the genera Indirana, Micrixalus, and Nyctibatrachus, toads like Pedostibes, Ghatophryne, and Xanthophryne, arboreal frogs like Ghatixalus, Mercurana, and Beddomixalus, and microhylids like Melanobatrachus are endemic to this region.[59]

Fishes and molluscs
Denison Barb is endemic to the region

The southern region of the Western Ghats exhibits greater fish species richness. There are 13 genera entirely restricted to the Western Ghats (Betadevario, Dayella, Haludaria, Horabagrus, Horalabiosa, Hypselobarbus, Indoreonectes, Lepidopygopsis, Longischistura, Mesonoemacheilus, Parapsilorhynchus, Rohtee, and Travancoria).[60] The most species-rich families are the Cyprinids (72 species), hillstream loaches (34 species; including stone loaches, now regarded a separate family), Bagrid catfishes (19 species), and Sisorid catfishes (12 species).[61] The region is home to several ornamental fishes including the endemic Denison barb,[62] melon barb, several species of Dawkinsia barbs, zebra loach, Horabagrus catfish, dwarf pufferfish and dwarf Malabar pufferfish.[63] The rivers are also home to Osteobrama bakeri, and larger species such as the Malabar snakehead, and Malabar mahseer.[64] A few are adapted to an underground life, including some Rakthamichthys swamp eels,[65] and the catfish Horaglanis and Kryptoglanis.[66] 97 freshwater fish species were considered threatened in 2011, including 12 critically endangered, 54 endangered, and 31 vulnerable.[60] The reservoirs in the region are important for their commercial and sport fisheries of rainbow trout, mahseer, and common carp.[67] There are more than 200 freshwater fish species including 35 also known from brackish or marine water.[68] Several new species have been described from the region since the last decade (e.g., Dario urops and S. sharavathiensis).[69][70]

Tamil lacewing, a butterfly found in the region[71]

Seasonal rainfall patterns in the Western Ghats necessitate a period of dormancy for its land snails, resulting in their high abundance and diversity, including at least 258 species of gastropods from 57 genera and 24 families.[72] A total of 77 species of freshwater molluscs (52 gastropods and 25 bivalves) have been recorded from the Western Ghats, but the actual number is likely higher.[60] This includes 28 endemics. Among the threatened freshwater molluscs are the mussel species Pseudomulleria dalyi, which is a Gondwanan relict, and the snail Cremnoconchus, which is restricted to the spray zone of waterfalls.[60] According to the IUCN, four species of freshwater molluscs are considered endangered and three are vulnerable. An additional 19 species are considered data deficient.[60]

Insects

There are roughly 6,000 insect species.[73] Of the 334 Western Ghats butterfly species, 316 species have been reported to occur in the Nilgiri Biosphere Reserve.[74] The Western Ghats are home to 174 species of odonates (107 dragonflies and 67 damselflies), including 69 endemics.[60] Most of the endemic odonate are closely associated with rivers and streams, while the non-endemics are typically generalists.[60] There are several species of leeches found all along the Western Ghats.[75]

Threats and conservation[edit | edit source]

Nilgiri Biosphere Reserve, the largest contiguous protected area in the Western Ghats

Historically, the Western Ghats were covered in dense forests, which formed the natural habitat for wildlife along with the native tribal people. Its inaccessibility made it difficult for people from the plains to cultivate the land and build settlements. After the establishment of British colonial rule in the region, large swathes of territory were cleared for agricultural plantations and timber. The forests in the Western Ghats were severely fragmented due to clear-felling for plantations.[76] The introduction of non-native species threatened the rare endemic species and habitat specialists, which depleted faster than other species.[77] Complex and species-rich habitats like the tropical rainforests are much more adversely affected than other habitats.[78] The primary threats to fauna were not only from habitat loss, but also from overexploitation, illicit grazing, mining, poaching, and introduced species.[60][35]

The Government of India has established many protected areas, including two biosphere reserves, 13 national parks to restrict human access, several wildlife sanctuaries to protect specific endangered species, and many reserve forests.[79] The Nilgiri Biosphere Reserve, comprising 5,500 km2 (2,100 sq mi) of the forests, forms the largest contiguous protected area in the Western Ghats.[80] In August 2011, the Western Ghats Ecology Expert Panel (WGEEP), appointed by the Union Ministry of Environment and Forests to assess the biodiversity and environmental issues of the Western Ghats, designated the entire region as an Ecologically Sensitive Area (ESA) and assigned three levels of Ecological Sensitivity to its different regions.[81][82] Subsequent committees formed have recommended various suggestions to protect the region.[83] In 2006, India applied to the UNESCO Man and the Biosphere Programme (MAB) for the Western Ghats to be listed as a protected World Heritage Site.[84] In 2012, 39 sites divided into seven clusters across the Western Ghats, were declared as World Heritage Sites.[85][86]
