Biodiversity Profile Of India:-
India, a megadiverse country with only 2.4% of the world’s land area, accounts for 7-8% of all recorded species, including over 45,000 species of plants and 91,000 species of animals
It is situated at the tri-junction of the Afrotropical, Indo-Malayan and Palaearctic realms, all of which support rich biodiversity.
Being one of the 17 identified megadiverse countries, India has 10 biogeographic zones and is home to 8.58% of the mammalian species documented so far, with the corresponding figures for avian species being 13.66%, for reptiles 7.91%, for amphibians 4.66%, for fishes 11.72% and for plants 11.80%
Four of the 34 globally identified biodiversity hotspots, namely the Himalaya, Indo-Burma, the Western Ghats-Sri Lanka and Sundaland, are represented in India
Bio-geographic classification and biodiversity characterization:-
India is amongst the few countries that have developed a bio-geographic classification based on which conservation planning has been taken up. This has been done to ensure
that different bio-geographic zones are represented in area-based conservation approaches at the landscape level.
This classification uses four levels of planning units: the biogeographic zone, the biotic province, the land region and the biome.
The Biogeographic Zone:-
Large distinctive units of similar ecology, biome representation, community and species, e.g., The Himalaya, The Western Ghats.
The biotic province:-
Secondary units within a zone, giving weight to particular communities separated by dispersal barriers or gradual change in environmental factors,e.g., North-west and West Himalaya either side of the Sutlej River.
The Land Region:-
A tertiary set of units within a province, indicating different landforms, e.g., Aravalli Mountains and Malwa Plateau in Gujarat-Rajwara Province.
A biome is an ecological unit, not a bio-geographic unit, such as swamp/wetland or temperate broad leaved forest.
The idea of hotspots was first mooted in 1988 by ecologist Norman Myers, who defined a hotspot as an area of exceptional plant, animal and microbe wealth that is under threat. The key criteria for determining a hotspot are endemism (the presence of species found nowhere else on earth) and degree of threat.
Out of the 34 global biodiversity hotspots, four are present in India.
1)THE HIMALAYA –
Western and Eastern Himalaya form part of Himalayan global biodiversity hotspot.
The sudden rise of the Himalayan mountains from less than 500 metres to more than 8,000 metres results in a diversity of ecosystems, from alluvial grasslands and subtropical broad-leaf forests along the foothills to temperate broad-leaf forests in the middle elevations, mixed conifer and conifer forests in the higher hills, and alpine meadows 2 above the tree line.
This enormous mountain range, which extends over nearly 750,000 km , lies in two separate regions of India, namely the Eastern Himalaya and the Western Himalaya. Charismatic large mammals such as the tiger and elephant are found in the foothills and Terai region. The Snow leopard, Musk deer, Himalayan tahr, Blue sheep, Black bear, Chir pheasant, Himalayan monal and Western tragopan are some of the characteristic fauna of the mountains. Of the estimated 10,000 species of plants in the Himalaya hotspot, 71 genera and approximately 3160 species are endemic.
The Eastern Himalayan region is exceptionally rich in diversity and endemism and hence is of great significance. The Eastern Himalaya on the whole has an estimated 9000 plant species, out of which 3500 (39%) are endemic. In the Indian portion of the Eastern Himalaya there occur 5800 plant species, approximately 2000 (36%) of which are endemic. The area is also rich in wild relatives of plants of economic significance, for example, rice, banana, citrus, ginger, chilli, jute and sugarcane. The region is also a rich centre of avian diversity-more than 60% of the bird species found in India have been recorded in the North-east. The region also harbours 35 endemic reptilian species including two genera of lizards and two turtle species. Out of 341 Indian amphibian species recorded so far, at least 68 species are known to occur in the North-east, 20 of which are endemic
2)THE WESTERN GHATS-
Part of Western Ghats-SriLanka global biodiversity hotspot.
The Western Ghats are part of the Western Ghats-Sri Lanka global hotspot, running roughly in a North-south direction for about 1500 kilometres parallel to the coast bordering the Arabian Sea. The importance of the Western Ghats in terms of their biodiversity can be seen from the known inventory of their plant and animal groups and the levels of endemism in these taxa. Western Ghats harbour 7388 species of flowering plants. Of these, 5584 species are indigenous, 377 are exotic naturalised and 1427 are cultivated or planted. Of the indigenous 5584 species, 2242 species are Indian endemics (found only in India) and 1261 are the Western Ghats endemics. Apart from the above, there are 586 taxa with subspecies and variety status, bringing total taxa in the Western Ghats to 7974.
The Western Ghats region harbours the largest global populations of the Asian elephant and possibly of other mammals such as the tiger, dhole and gaur. The Western Ghats also support a number of wild relatives of cultivated plants, including pepper, cardamom, mango, jackfruit and sandal.
Thirty nine sites in the Western Ghats in the States of Kerala, Karnataka, Tamil Nadu and Maharashtra were inscribed in the UNESCO World Heritage List in 2012, considering their outstanding universal value and high levels of endemism.
Part of Indo-Burma global biodiversity hotspot.
Some parts of the North-eastern region of India, excluding the Himalayan region, are contiguous with the Indo-Burma biodiversity hotspot, centred on the Indo-Chinese Peninsula, and comprising Cambodia, the Lao People’s Democratic Republic, Myanmar, Thailand, Vietnam and parts of Southern China.
The topography of the hotspot is complex and is characterised by a series of North-south mountain ranges that descend from the Himalayan chain and its South-eastern
Indo-Burma probably supports the highest diversity of freshwater turtle in the world. The hot spot also has a remarkable freshwater fish fauna, with 1262 documented species, accounting for about 10% of the world total, including 566 endemics
Part of the Sundaland global biodiversity hotspot.
The Nicobar Islands are part of the Sundaland hotspot, which includes a small portion of Southern Thailand;nearly all of Malaysia; Singapore, at the tip of the Malay Peninsula; all of Brunei Darussalam; and all of the western half of the mega-diverse country of Indonesia,including Kalimantan.
These islands are fringed by one of the most spectacular reefs of the Indian Ocean region and are considered to be globally significant.
The Nicobar Islands are characterised by an absence of large mammals and the presence of a significant number of endemics, such as Nicobar tree shrew (Tupaia nicobarica), among the island’s vertebrates.
The only primate, the Nicobar Crab-eating macaque (Macaca fascicularis umbrosa), occurs in the Southern group of the Nicobar Islands.
Importance of biodiversity and its implications for human well-being:-
Biodiversity underpins the form and function of ecosystems, which are of high value due to the life-supporting services they provide that meet human needs, both material and non-material.
They are provisioning services, such as supplying of fuel and fodder, and regulating services, such as carbon sequestration and prevention of soil erosion. Moreover, biodiversity has non-use or existence value.
In the Indian context especially, a range of socio-cultural values are derived from biodiversity that are philosophical, cultural and religious. Biodiversity and ecosystem diversity are reflected in the cultural and religious diversity of India through the varied values attached to biodiversity components and landscapes. India’s many traditional knowledge systems and ethno-medicinal practices are based on a close understanding of and dependence on biodiversity. The cultural or religious importance of species and designation of sacred areas are well-known in India.
India’s coastal and marine areas hold many biological treasures. Dense mangrove forest of Sunderbans, the world’s largest congregations of nesting turtles in Odisha, beautiful seagrass beds in Palk Bay, dolphins and dugongs in the Gulf of Mannar, majestic whale sharks in the Gulf of Kachchh and some of the world’s most beautiful coral reefs are just a few examples of the treasures of India’s coastal and marine biodiversity
Forests of India:-
The forests in India are spread over an area of 2 692,027 km , covering 21.05% of the geographical area of the country.
There are 16 major forest types and 251 sub-types
The forest cover of the country has been classified on the basis of the tree canopy density into pre-defined classes: Very Dense Forest (VDF), Moderately Dense Forest
(MDF) and Open Forest (OF).
Forest cover percentage-
a) VDF – 2.54
b) MDF -9.76
c) OF – 8.75
Wetlands of India
India is bestowed with a rich diversity of wetlands, ranging from high altitude lakes of the Himalayas, floodplains and marshes of the Gangetic – Bramhaputra alluvial plains, saline flats of Green Indian Desert to extensive mangroves marshes bordering the country’s East and West coastline.
Roughly equal to 4.6% of India’s land area is wetland.
India is a signatory to Ramsar Convention and is committed to ‘wise use’ of all wetlands in her territory. As on date, 26 sites have been designated as Wetlands of International importance under the Convention.
Important Wetlands of India:-
- Ashtamudi Wetland – Kerala
- Bakhira Wildlife Sanctuary – Uttar pradesh
- Bhoj Lake – Madhya Pradesh
- Chilika Lagoon – Odisha
- Deepor Beel – Assam
- Kolleru Lake – Andhra Pradesh
- Loktak Lake – Manipur
- Nalsarovar – Gujrat
- North Reef Island Sanctuary – Andaman & Nicobar Islands
- Point Calimere Wildlife and Bird Sanctuary – Tamilndau
- Pong Dam Lake – Himachal Pradesh
- Sambhar Lake – Rajasthan
- Sundarbans – West Bengal
- Tawa Reservoir – Madhya Pradesh
- Tso Moriri – Jammu & Kashmir
- Udhwa Lake (Bird Sanctuary) – Jharkhand
- Wular Lake – Jammu & Kashmir
- Wandur Marine National Park – Andaman & Nicobar Islands
Wetlands are one of the crucial natural resources. Wetlands are areas of land that are either temporarily or permanently covered by water. This means that a wetland is neither truly aquatic nor terrestrial; it is possible that wetlands can be both at the same time depending on seasonal variability. Thus, wetlands exhibit enormous diversity according to their genesis, geographical location, water regime and chemistry, dominant plants and soil or sediment characteristics.
Because of their transitional nature, the boundaries of wetlands are often difficult to define. Wetlands do, however, share a few attributes common to all forms. Of these, hydrological structure (the dynamics of water supply, throughput, storage and loss) is most fundamental to the nature of a wetland system. It is the presence of water for a significant period of time, which is principally responsible for the development of a wetland
The Millennium Ecosystem Assessment estimates conservatively that wetlands cover seven percent of the earth’s surface and deliver 45% of the world’s natural productivity and ecosystem services of which the benefits are estimated at $20 trillion a year
Provisioning services: The resources or products provided by ecosystems, such as food, raw materials (wood), genetic resources, medicinal resources, ornamental resources (skin, shells, flowers).
Regulating services: Ecosystems maintain the essential ecological processes and life support systems, like gas and climate regulation, water supply and regulation, waste treatment, pollination, etc.
Cultural and Amenity services: Ecosystems are a source of inspiration to human culture and education throughout recreation, cultural, artistic, spiritual and historic information, science and education.
Supporting services: Ecosystems provide habitat for flora and fauna in order to maintain biological and genetic diversity.
Mangroves, corals and seagrasses:-
India has a long coastline of about 7,517 km in length- 2 consisting of 2,383 km of extensive coral reef beds.
The coral reef beds in the Gulf of Kachchh, Gulf of Mannar, Lakshadweep Islands and Andaman and Nicobar Islands are inhabited by several rare and threatened species such as the dugong, the Hawksbill turtle and Giant clams, which indicate the health of these ecosystems.
A total of 478 species of corals belonging to 89 genera have so far been recorded from India, forming 60% of the known hermatypic genera of the world.
The mangrove cover of India (2.69% of the global mangrove area and 8% of Asia’s mangroves) is home to umbrella species such as the tiger as well as many threatened species such as the River terrapin, Gangetic river dolphin, Estuarine crocodile and Fishing cat.
*Umbrella species are species selected for making conservation-related decisions, typically because protecting these species indirectly protects the many other species that make up the ecological community of its habitat. Species conservation can be subjective because it is hard to determine the status of many species.
About 59% of this cover is on the East coast, along the Bay of Bengal, 28% on the West coast, bordering the Arabian Sea, and 13% on the Andaman and Nicobar Islands.
The largest mangrove habitat is found in the Sundarbans, West Bengal. It is the single largest block 2 (>10,000 km ) of tidal halophytic mangroves in the world.
Seagrasses are submerged aquatic vegetation specialised to live in marine environments.They are acting as the carbon sink in the coastal environment by sequestering
12% of the carbon fixed in the global oceans.
In India, extensive seagrass meadows are reported from Gulf of Mannar, Palk Bay, Gulf of Kachchh, Lakshadweep and Andaman and Nicobar group of islands.
Marine protected area network in India:-
India has a vast coastline of 7517 km, of which 5423 km is in peninsular India and 2094 km in the Andaman, Nicobar 2 and Lakshadweep Islands, with an exclusive economic zone of 2.02 million km . This coastline also supports a huge human population, which is dependent on the rich coastal and marine resources. It is estimated that nearly 250 million
people live within a swath 50 km wide along the coastline of India.
Therefore, the ecological services of the marine and coastal ecosystems of India play a vital role in India’s economic growth and in ensuring human well-being. The MPA network in India has been used as a tool to manage natural marine resources for biodiversity conservation and for the well-being of people dependent on these resources. India has designated four legal categories of PAs, National Parks, Wildlife Sanctuaries, Conservation Reserves and Community Reserves. Scientific monitoring and traditional observations confirm that depleted natural marine resources are getting restored and/or pristine ecological conditions have been sustained in well managed MPAs.
There are 23 MPAs present in peninsular India and more than 100 MPAs in the country’s islands. Of the 23 MPAs in the peninsula, Gulf of Mannar Marine National Park, Sundarbans National Park, Gulf of Kachchh National Park, Gahirmatha Marine Sanctuary, Coringa Wildlife Sanctuary, Chilika Wildlife Sanctuary have unique marine biodiversity and provide a range of ecological services to the local communities. These 23 MPAs cover an area of about 6158 km , which is 3.85% of the total area covered under the entire PA network of India 2 or less than 0.2% of the total land area of India. The total area of the Andaman and Nicobar Islands is 4947 km , of 2 which 1510 km is protected under the provisions of India’s Wildlife (Protection) Act, 1972. There are 105 PAs in the Andaman and Nicobar Islands, of which about 100 include marine areas. These MPAs cover more than 30% of the terrestrial area of the islands and protect more than 40% of the coastal habitat. Mahatma Gandhi Marine National Park and Rani Jhansi Marine National Park are important MPAs here. In the Lakshadweep group of islands, Pitti Island (0.012 km ) is the only island having the status of an MPA.
Ecologically Sensitive Areas (ESAs):-
Biosphere Reserves (BRs):-
National Biosphere Reserve Programme in 1986 with the primary aim of conservation of an entire range of living resources and their ecological foundations, along with sustainable use of natural resources and improvement of the livelihoods of local inhabitants. This programme also had the objective of ensuring community participation for ffective management of biodiversity resources and integration of traditional knowledge and scientific research for conservation, education and training as a part of the overall management of BRs. Considering the diversity of ecosystems and recognising the importance of BRs in ensuring long-term conservation and sustainable use of India’s
representative and diverse biological diversity, so far 18 BRs have been notified by the GoI. Globally, the World Network of Biosphere Reserves (WNBR) has designated a total of
621 BRs, of which 9 are in India. These are the Achanakmar-Amarkantak, Nilgiri, Gulf of Mannar, Nanda Devi, Sundarban, Simlipal, Pachmarhi, Nokrek and Great Nicobar BR.
Important Bird Areas (IBAs)
Birds are good indicators of ecosystem health. The IBA programme of BirdLife International aims to identify, monitor and protect a global network of IBAs for conservation of the world’s birds and other biodiversity. The IBAs are conservation areas of international significance for conservation of birds at the global, regional or sub-regional level. According to BirdLife International, designation of IBAs is based on standardised criteria, namely (i) hold significant numbers of one or more globally threatened bird species, (ii) be one of a set of sites that together hold a suite of restricted-range species or biome-restricted.(iii) have exceptionally large numbers of
migratory or congregatory birds.
The Bombay Natural History Society (BNHS; www.bnhs.org) and BirdLife International have identified 465 IBAs in India
Key Biodiversity Areas (KBAs)
KBAs are nationally identified sites of global significance. In India, the identification of KBAs in the Western Ghats was initiated in 2003.KBAs comprise an ‘umbrella’ which includes globally important sites for different taxa and realms: IBAs, Medicinal Plant Conservation Areas (MPCAs), Important Sites for Freshwater/Marine Biodiversity; and Alliance
for Zero Extinction (AZE) sites.
Alliance for Zero Extinction (AZE)The AZE (www.zeroextinction.org) is a global alliance, which identifies threatened species (CR and EN), based on the global IUCN Red Listing, occurring in a single location, as the highest priority in initiating on-the ground conservation action.
Currently there are 19 species recognized by the AZE in India, The Zoo Outreach Organization (ZOO; www.zooreach.org) and the Indian Alliance for Zero Extinction (In AZE; www.zooreach.org/indianaze/ indianaze.html) have identified a further 40 species and sites based on the recent assessments of freshwater fish and aquatic plants.
Community Conservation Areas (CCAs)
CCAs can be defined as ‘natural ecosystems (forest/marine/wetlands/grasslands/others), including those with minimum to substantial human influence, containing significant wildlife and biodiversity values, being conserved by communities for cultural, religious, livelihood, or political purposes, using customary laws or other effective means’.
A total of 141 CCAs covering a total area of ca. 157,046 ha have been identified for conservation measures.
Medicinal Plant Conservation Areas (MPCAs)
India has one of the richest and oldest medicinal plant cultures of the world. The so far estimated number of 6560 species of medicinal plants of India are a great bio-cultural resource Foundation for Revitalization of Local Health and Traditions.
The uniqueness of the Indian medical heritage draws from two streams of knowledge, folk and codified stream, which are coexisting living traditions that have historically
enjoyed a symbiotic relationship. India is a global leader in in-situ conservation of medicinal plants having established the largest in-situ conservation network for medicinal plants in the tropical world.
So far, 110 MPCAs, each of an average size of 200 ha, have been set up across 13 States of India.
Flagship Species of India
The Tiger Panthera tigris is an umbrella species for conservation of the biota of a majority of the eco-regions in Asia. Its role as a top predator is vital in regulating and maintaining ecological processes and systems. India is home to over 50% of the world’s wild tigers in spite of having a growing human population of over a billion.
Major landscape complexes that inhabit tiger:-
1)Shiva-Gangetic Plain Landscape
2)Central Indian Landscape Complex and Eastern Ghats Landscape
3)Western Ghats Landscape
4)North Eastern Hills and Brahmaputra Flood Plans
The Elephant (Elephas maximus) has enjoyed a unique association with the people of India since ancient times and is worshiped in Hindu and Buddhist cultures. It occurs in the central and Southern Western Ghats, North-east India, Eastern India and Northern India and in some parts of Southern peninsular India.
It is included in Schedule I of the Indian Wildlife (Protection) Act, 1972 and in Appendix I of the Convention on International Trade in Endangered Species of Flora and Fauna(CITES).
In 1992 GoI launched Project Elephant, a flagship conservation project that aims to conserve the elephant and its habitat across 10 major landscapes (designated as Project
Elephant Ranges), mitigate elephant – human conflict, and protect the animal from poaching for ivory.
Asiatic Wild ass:-
The Asiatic Wild ass Equus hemionus khur is restricted to the Rann of Kachchh in Gujarat and its surrounding areas. The population of this sub-species has been on the increase since the 1990s.
Gharial is Critically Endangered (IUCN), and listed in Schedule I Wildlife Protection Act (WPA, 1972). About 1300 animals are estimated to be left in the wild, of which only about 200 are breeding adults. The largest remaining populations are found in just four locations in India, along the Son, Katerniaghat, Girwa and Chambal rivers.
Irrawaddy dolphin is found in Chilika Lake and the Sundarbans, these dolphins have suffered a rapid decline in their population mainly due to poaching and accidental catches in gill nets. Conservation work carried out by the Chilika Development Authority (CDA) has resulted in an increasing trend in the population of the Irrawaddy dolphin, with the
numbers increasing from 70 in 2003 to 145 in 2012.
Project Kachuga, an initiative undertaken by the Madras Crocodile Bank Trust in collaboration with Turtle Survival Alliance, has been launched for conservation of freshwater turtles in India. Five turtle priority areas have been identified for development and implementation of effective conservation plans under this programme.
Listed as Vulnerable (IUCN 2013, Figure 1.17) and protected under Schedule I of the WPA, 1972, dugong occurs in the Gulf of Mannar, Palk Bay, Gulf of Kachchh and Andaman and Nicobar Islands. The MoEF, under the species recovery component of the IDWH scheme, aims at increasing Dugong numbers and preventing degradation of the habitat of the species.
Myristica swamps are a type of freshwater swamp forest predominantly composed of species of Myristica, the most primitive of the flowering plants on earth. These are found in two localities in India, the Uttara Kannada district of the State of Karnataka and in the Southern parts of the State of Kerala.
Myristica swamps are ‘live museums’ of ancient tree species and the home of proto-angiosperms
Cycads are the remnants of the most ancient seed plants. These plants date to the late Carboniferous period (300-325 million years ago). They are flagship species for conservation biology due to their unusual life histories, restricted distribution in special habitats and the globally threatened status of many species
Cycads are used extensively for medicinal and other subsistence purposes. Cycads in India are now receiving much-needed attention for conservation through both ex situ and in situ measures.
It is a ‘keystone element’ in the Himalayan context.The Eastern Himalayan region is particularly rich, being represented by 75 species. The hills of North-eastern India account for about 10 species, of which six are endemic.
As many as 46 Rhododendron species have been classified as rare or threatened in the Eastern Himalaya of India.
The State Government of Sikkim has specially declared two PAs as Rhododendron Sanctuaries, Shingba and Barsey. Fambonglho Wildlife Sanctuary, Kyongnosla Alpine Sanctuary and Maenam Wildlife Sanctuary are the other PAs in Sikkim that are known for Rhododendron conservation.
It is rare, classified globally as endangered and included in Appendix I of CITES and the Negative List of Exports of the GoI.
The plant is endemic to the State of Meghalaya and is found at altitudes of approximately 1000-1500 m in the Khasi, Jaintia and Garo hills .
India is regarded as the home and one of the centres of origin of Citrus due to the presence of a vast genetic diversity of important Citrus species (family Rutaceae).
Seven Indian Citrus species are categorized as endangered by the IUCN. An initiative was undertaken by NBPGR (National Bureau of Plant Genetic Resources0in 1981 to protect Citrus germplasm in the wild by establishing the Citrus Gene Sanctuary, covering an area of approximately 10,266 ha, located in the buffer zone of the Nokrek Biosphere Reserve, in the Garo Hills of Meghalaya, with support from the MoEF, under the Man and Biosphere Reserve Programme of the United Nations
Orchids are a charismatic group that form 9% of India’s flora and are the largest family among higher plants in India.The Himalayan region is their main home, and others are
scattered in the Eastern and Western Ghats.
Orchid diversity in India is high, comprising terrestrial, epiphytic and saprophytic orchids. In general, terrestrial orchids are more common in western India, epiphytic orchids in North-eastern India and small-flowered orchids in the Western Ghats.
Sessa Orchid Sanctuary, at Arunachal Pradesh, with more than 600 species, is the orchid paradise of the country. Agastyamalai Hills, in southern Kerala, home to at least 150 endemics species.

Green India Mission (GIM):-
GIM is one of the eight missions under the NAPCC. The objectives of the Mission include increased forest/tree cover on 5 m ha of forest/non- forest lands and improved quality of forest cover on another 5 m ha of non-forest/ forest lands.
India has an estimated 18,000 plants, 30 mammals, 4 birds, 300 freshwater fishes and 1100 arthropods that are invasive.Among the major threats faced by native plant and animal species (and their habitats), the one posed by the Invasive Alien Species, is considered second only to habitat loss. Invasive Alien Species are species whose introduction and/or spread outside their natural habitats threaten biological diversity. While only a small percentage of organisms transported to new environment become invasive, their negative impacts on food security, plant, animal and human health, and economic development can be extensive and substantial. Identification, monitoring and management of all Invasive Alien Species in India is a major challenge as in other parts of the world. Addressing the problem of Invasive Alien Species is urgent because the threat is increasing due to global trade, transport, and tourism with several social, economic and environmental impacts.
Many fresh water and marine algae including species of Kappaphycus (red algae), Microcystis ( freshwater cyanobacteria), Caulerpa (seaweeds ), Cladophora (green algae), etc. causing extensive damage to the ecosystems and affecting aquatic biodiversity adversely in India have been identified.
The invasive Carijoa riisei (snowflake coral or branched pipe coral) is found in Andaman and Nicobar Islands, Gulf of Mannar and Gulf of Kachchh.
A recent report on the occurrence of the Spider crab Acanthonyx euryseroche, a seaweed associate along the Central West Coast of India suggests that the epidemic outburst of such population might be dangerous to native marine biodiversity in India.
Of the eight worst invasive fish species in the world, five species are present in India. For example, Mosquito fish (Gambusia affinis) was introduced in India as a biological control.Brown trout (Salmo trutto) and Rainbow trout (Oncorhynchus mykiss) were introduced in streams and rivers of Himalayas for recreational as well as consumption purposes. These three highly predatory fishes eat the eggs of economically desirable fish and prey on an endanger rare indigenous fish and invertebrate species. Common carp (Cyprinus carpio) and Mozambique tilapia (Oreochromis mossambucus), were introduced in Indian aquaculture but later these species spread into large parts of India and are now competing with native species in for food and habitat. African cat fish Clarias gariepinus has been identified as a highly invasive fish in the Indian freshwater ecosystem and is posing a threat to native fish as well as other aquatic animals.
