The creek begins near the Chetinnad Palace, extending northward into the mainland and taking a complete U-turn near the Foreshore Estate before ending near Mandavelipakkam. The creek surrounds the Quibble Island.Chembarambakkam Lake
Chembarambakkam lake, is a lake located in Chennai, Tamil Nadu, India, about 25 km from Chennai. It is one of the two rain-fed reservoirs from where water is drawn for supply to Chennai City, the other one being the Puzhal Lake. The Adyar River originates from this lake. A part of water supply of the metropolis of Chennai is drawn from this lake.
During Chennai's water crisis of 2019, Chembarambakkam Lake dried up.Ennore creek
Ennore creek is a backwater located in Ennore, Chennai along the Coromandel Coast of the Bay of Bengal. It is located in the zone comprising lagoons with salt marshes and backwaters, submerged under water during high tide and forming an arm of the sea with the opening to the Bay of Bengal at the creek. The zone is spread over an area of 4 km2, and the creek covers an area of 2.25 km2. It is located 20 km north of the city centre and 2.6 km south of the Ennore Port, and the creek area stretches 3 km into the sea and 5 km along the coast. The creek is nearly 400 m wide, elongated in northeast-southwest direction and merging with the backwater bodies. Once a flourishing mangrove swamp, the creek has been degraded to patches in the fringes mainly due to human activities in the region. The depth of the creek varies from 1 to 2 m and is shallow near the mouth. The north–south trending channels of the creek connect it with the Pulicat Lake to the north and to the distributaries of the Kosasthalaiyar River in the south. The northwestern part of the creek merges with the tidal flats. The soil in the region is of loamy and alluvial types. Most of the area consists of tracts of alluvial soil and the eastern region comprises beach dunes, tidal flats and creek. The creek is oriented from west to east and opens into the Bay of Bengal to the east at Ennore. The creek acts as an outlet for the excess water from the Poondi Reservoir. The creek separates the town of Ennore from the Ennore Port located in the north and the Kattupalli Shipyard located further north. The North Chennai Thermal Power Station is located at the north of the creek and the Ennore Thermal Power Station is located to the south. The creek is part of the Pulicat water system, including the Pulicat lagoon and the Buckingham Canal. As per the 1991 Coastal Regulation Zone notification, the entire Pulicat water system is designated CRZ I. The creek is experiencing siltation due to emergence of the Ennore Port.Fauna of India
India has some of the world's most biodiverse regions. The political boundaries of India encompass a wide range of ecozones—desert, high mountains, highlands, tropical and temperate forests, swamplands, plains, grasslands, areas surrounding rivers, as well as island archipelago. It hosts
4 biodiversity hotspots:the Himalayas, the Western Ghats, the Indo-Burma region and the Sundaland (Includes Nicobar group of Islands). These hotspots have numerous endemic species.India, for the most part, lies within the Indomalaya ecozone, with the upper reaches of the Himalayas forming part of the Palearctic ecozone; the contours of 2000 to 2500m are considered to be the altitudinal boundary between the Indo-Malayan and Palearctic zones. India displays significant biodiversity. One of seventeen megadiverse countries, it is home to 7.6% of all mammalian, 12.6% of all avian, 6.2% of all reptilian, 4.4% of all amphibian, 11.7% of all fish, and 6.0% of all flowering plant species.The region is also heavily influenced by summer monsoons that cause major seasonal changes in vegetation and habitat.
India forms a large part of the Indomalayan biogeographical zone and many of the floral and faunal forms show Malayan affinities with only a few taxa being unique to the Indian region. The unique forms includes the snake family Uropeltidae found only in the Western Ghats and Sri Lanka. Fossil taxa from the Cretaceous show links to the Seychelles and Madagascar chain of islands. The Cretaceous fauna include reptiles, amphibians and fishes and an extant species demonstrating this phylogeographical link is the purple frog. The separation of India and Madagascar is traditionally estimated to have taken place about 88 million years ago. However, there are suggestions that the links to Madagascar and Africa were present even at the time when the Indian subcontinent met Eurasia. India has been suggested as a ship for the movement of several African taxa into Asia. These taxa include five frog families (including the Myobatrachidae), three caecilian families, a lacertid lizard and freshwater snails of the family Potamiopsidae. A thirty million year old Ologocene era fossil tooth from the Bugti Hills of central Pakistan has been identified as from a lemur-like primate, prompting controversial suggestions that the lemurs may have originated in Asia. Lemur fossils from India in the past led to theories of a lost continent called Lemuria. This theory however was dismissed when continental drift and plate tectonics became well established.
The flora and fauna of India have been studied and recorded from early times in folk traditions and later by researchers following more formal scientific approaches (See Natural history in India). Game laws are reported from the third century BC.A little under 5% of this total area is formally classified under protected areas.
India is home to several well-known large mammals, including the Asian elephant, Bengal tiger, Asiatic lion, leopard and Indian rhinoceros. Some of these animals are engrained in culture, often being associated with deities.
These large mammals are important for wildlife tourism in India, and several national parks and wildlife sanctuaries cater to these needs. The popularity of these charismatic animals have helped greatly in conservation efforts in India. The tiger has been particularly important, and Project Tiger, started in 1972, was a major effort to conserve the tiger and its habitats. Project Elephant, though less known, started in 1992 and works for elephant protection. Most of India's rhinos today survive in the Kaziranga National Park.
Some other well-known large Indian mammals are: ungulates such as the water buffalo, nilgai, gaur and several species of deer and antelope. Some members of the dog family such as the Indian wolf, Bengal fox, golden jackal and the dhole or wild dogs are also widely distributed. It is also home to the striped hyaena. Many smaller animals such as macaques, langurs and mongoose species are especially well known due to their ability to live close to or inside urban areas Adhu.Guindy National Park
Guindy National Park is a 2.70 km2 (1.04 sq mi) protected area of Tamil Nadu, located in Chennai, India, is the 8th-smallest National Park of India and one of the very few national parks situated inside a city. The park is an extension of the grounds surrounding Raj Bhavan, formerly known as the 'Guindy Lodge', the official residence of the Governor of Tamil Nadu, India. It extends deep inside the governor's estate, enclosing beautiful forests, scrub lands, lakes and streams.
The park has a role in both ex-situ and in-situ conservation and is home to 400 blackbucks, 2,000 spotted deers, 24 jackals, a wide variety of snakes, geckos, tortoises and over 130 species of birds, 14 species of mammals, over 60 species of butterflies and spiders each, a wealth of different invertebrates—grasshoppers, ants, termites, crabs, snails, slugs, scorpions, mites, earthworms, millipedes, and the like. These are free-ranging fauna and live with the minimal of interference from human beings. The only major management activity is protection as in any other in-situ conservation area. The park attracts more than 700,000 visitors every year.Madras Naturalists' Society
Madras Naturalists' Society is a non-governmental organization that promotes appreciation, education and conservation of Nature. It was founded by bird watchers from the city of Madras (now Chennai), India) on 17 May 1978. G. K. Bhat was the organization's first President. The logo of the society is a Blackbuck
The society started publishing a monthly bulletin from December 1978 and a quarterly journal Blackbuck from January 1985 Blackbuck carries semi-technical articles and works of popular interest. The digitised Version of 'Blackbuck' and the monthly bulletin was unveiled on 2 July 2015 to the members. An anthology of writings from the Blackbuck titled Sprint of the Blackbuck was published in 2012. The volume was edited by noted Tamil film historian and Madras Naturalists' Society member S. Theodore Baskaran.
Starting from Madhavaiah Krishnan's birth centenary year in 2012, the society annual presents a "M. Krishnan Memorial Nature Writing Award" for young wildlife writers.Nanmangalam Reserve Forest
Nanmangalam Reserve Forest is a protected forest located in the southern part of Chennai, about 24 km from the city centre. It is located at Medavakkam on Velachery High Road between Velachery and Tambaram. The reserve forest has an area of 320 hectares. However, the total area of the forest is 2,400 hectares.
The forest is popular among bird watchers and is home to about 85 species of birds. Red-wattled lapwing, crested honey buzzard, grey partridge, coucal, Indian eagle-owl, white-breasted kingfisher, pied kingfisher, southern bush lark and red-whiskered bulbul are commonly seen in the area.The 320-hectare Nanmangalam Reserved Forest, located about 10 km from Velachery, is a scrubland around an abandoned granite quarry and is home to some of the rare territorial orchids, according to a recent study.The state forest department has entrusted the work of data collection in this small forest area to Care Earth, a bio-diversity research organisation. Located near Medavakkam, a rapidly developing residential locality, the forest needs immediate fencing to protect it from encroachment and to curtail any non-forestry activity there, the study says.The neighbourhood of Nanmangalam is one of the 163 notified areas (megalithic sites) in the state of Tamil Nadu.Nelapattu Bird Sanctuary
Nelapattu Bird Sanctuary is a bird sanctuary in Nellore district, Andhra Pradesh, India, near the village of Nelapattu. It has an area of 458.92 hectares. It is an important breeding site for spot-billed pelicans (Pelecanus philippensis).Nelapattu has two major plant communities, Barringtonia swamp forests and southern dry evergreen scrub.
Southern dry evergreen scrub covers most of the sanctuary, including the 288 hectares of Kalluru Reserved Forest and 88 hectares of unreserved forest. The dominant tree and shrub species are Manilkara hexandra, Maba buxifolia, Memecylon edule, Buchanania angustifolia, Zizyphus xylopyrus, and others.The Barringtonia swamp forests are found in the 83-ha Nelapattu tank. The predominant tree species is Barringtonia acutangula (Hijal). This tree also grows in uplands, but the tree species found at Nelapattu can grow in flooded conditions lasting for 5 to 7 months. The saplings can survive total submersion during the long duration of flooding.About 189 bird species can be found at Nelapattu Bird Sanctuary, 50 of which are migratory. In addition to the spot-billed pelican, it is an important breeding site for white ibis, openbill stork, night heron, and little cormorant. Other migratory water birds that visit the sanctuary include pintail, common teal, dabchick, shoveler, coot, spot-bill duck, grey heron, darter, black-winged stilt, and garganey gadwall.Pallikaranai wetland
Pallikaranai wetland is a freshwater marsh in the city of Chennai, India. It is situated adjacent to the Bay of Bengal, about 20 kilometres (12 mi) south of the city centre, and has a geographical area of 80 square kilometres (31 sq mi). Pallikaranai marshland is the only surviving wetland ecosystem of the city and is among the few and last remaining natural wetlands of South India. It is one of the 94 identified wetlands under National Wetland Conservation and Management Programme (NWCMP) operationalised by the Government of India in 1985–86 and one of the three in the state of Tamil Nadu, the other two being Point Calimere and Kazhuveli. It is also one of the prioritised wetlands of Tamil Nadu. The topography of the swamp is such that it always retains some storage, thus forming an aquatic ecosystem. A project on 'Inland Wetlands of India' commissioned by the Ministry of Environment and Forests, Government of India had prioritised Pallikaranai marsh as one of the most significant wetlands of the country. The marsh contains several rare or endangered and threatened species and acts as a forage and breeding ground for thousands of migratory birds from various places within and outside the country. The number of bird species sighted in the wetland is significantly higher than the number at Vedanthangal Bird Sanctuary.Indiscriminate dumping of toxic solid waste along the road, discharge of sewage, and construction of buildings, railway stations and a new road to connect Old Mahabhalipuram Road and Pallavaram have shrunk the wetland to a great extent. In 2007, as an effort to protect the remaining wetland from shrinking further, the undeveloped areas in the region were notified as a reserve forest. A 2018 study showed that about 60 percent of the native species in the wetland, including hoorahgrass (Fimbristylis), dwarf copperleaf or ponnanganni keerai (Alternanthera sessilis), floating lace plant or kottikizhangu (Aponogeton natans), wild paddy (Oryza rufipogon), crested floating heart (Nymphoides), and nut grass (Cyperus), have been replaced by invasive species.Wildlife of India
India is home to a variety of animals. Apart from a handful of domesticated animals, such as cows, water buffaloes, goats, chickens, and both Bactrian and Dromedary camels, India has a wide variety of animals native to
the country. It is home to Bengal and Indochinese tigers, Asiatic lions, Indian and Indochinese leopards, snow leopards, clouded leopards, various species of Deer, including Chital, Hangul, Barasingha; the Indian Elephant, the Great Indian Rhinoceros, and many others. The region's diverse wildlife is preserved in more than 120 national parks, 18 Bio-reserves and more than 500 wildlife sanctuaries across the country. India has some of the most biodiverse regions of the world and contains four of the world’s 36 biodiversity hotspots – the Western Ghats, the Eastern Himalayas, Indo-Burma and Sunda Land. Wildlife management is essential to preserve the rare and endangered endemic species. India is one of the seventeen megadiverse countries. According to one study, India along with the other 16 megadiverse countries is home to about 60-70% of the world's biodiversity. India, lying within the Indomalaya ecozone, is home to about 7.6% of all mammalian, 12.6% of avian (bird), 6.2% of reptilian, and 6.0% of flowering plant species.Many Indian species are descendants of taxa originating in Gondwana, of which India originally was a part. Peninsular India's subsequent movement towards, and collision with, the Laurasian landmass set off a mass exchange of species. However, volcanism and climatic change 20 million years ago caused the extinction of many endemic Indian forms. Soon thereafter, mammals entered India from Asia through two zoogeographical passes on either side of the emerging Himalaya. As a result, among Indian species, only 12.6% of mammals and 4.5% of birds are endemic, contrasting with 45.8% of reptiles and 55.8% of amphibians. Notable endemics are the Nilgiri leaf monkey and the brown and carmine Beddome's toad of the Western Ghats. India contains 172, or 2.9%, of IUCN-designated threatened species. These include the Asian elephant, the Asiatic lion, Bengal tiger, Indian rhinoceros, mugger crocodile, and Indian white-rumped vulture, which suffered a near-extinction from ingesting the carrion of diclofenac-treated cattle.In recent decades, human encroachment has posed a threat to India's wildlife; in response, the system of national parks and protected areas, first established in 1935, was substantially expanded. In 1972, India enacted the Wildlife Protection Act and Project Tiger to safeguard crucial habitat; further federal protections were promulgated in the 1980s. Along with over 515 wildlife sanctuaries, India now hosts 18 biosphere reserves, 10 of which are part of the World Network of Biosphere Reserves; 26 wetlands are registered under the Ramsar Convention.
The peepul tree, shown on the seals of Mohenjo-daro, shaded Gautama Buddha as he sought enlightenment. The varied and rich wildlife of India has had a profound impact on the region's popular culture. The wildlife has also been made famous in The Jungle Book by Rudyard Kipling. India's wildlife has been the subject of numerous other tales and fables such as the "Panchatantra".
