Harike Wetland

Harike Wetland also known as "Hari-ke-Pattan", with the Harike Lake in the deeper part of it, is the largest wetland in northern India in the border of Tarn Taran Sahib district and Ferozepur district of the Punjab state in India.

The wetland and the lake were formed by constructing the headworks across the Sutlej river in 1953. The headworks is located downstream of the confluence of the Beas and Sutlej rivers just south of Harike village. The rich biodiversity of the wetland which plays a vital role in maintaining the precious hydrological balance in the catchment with its vast concentration of migratory fauna of waterfowls including a number of globally threatened species (stated to be next only to the Keoladeo National Park near Bharatpur) has been responsible for the recognition accorded to this wetland in 1990, by the Ramsar Convention, as one of the Ramasar sites in India, for conservation, development and preservation of the ecosystem.http://ramsar.wetlands.org/Portals/15/India.pdf Wetland name: Harike Lakehttp://www.ramsar.org/forum/forum_india_harike.htm Update on the Harike Wetland, Indiahttp://www.punenvis.nic.in/water_wetland_status.htm . Status of wetlands

This man-made, riverine, lacustrine wetland spreads into the three districts of Tarn Taran Sahib, Ferozepur and Kapurthala in Punjab and covers an area of 4100 ha. Conservation of this wetland has been given due importance, since 1987–88, both by the Ministry of Environment and Forests, Government of India and the Punjab State Government (through its several agencies), and over the years several studies and management programmes have been implemented.http://www.pscst.com/en/pdfs/Conservation%20Programmes%20for%20Wetlands.pdf Conservation Programmes for Wetlands

Access

Harike or Hari-ke-Pattan as it is popularly called, is the nearest town to the wetland is Makhu (Ferozepur) Railway Station and Bus Stand is situated 10 km south of the Harike town, which connects to Ferozpur, Faridkot and Bhatinda by the National Highway.

Hydrology and engineering aspects

Monsoon climate dominates the catchment draining into the wetland. The headworks built on the Sutlej River downstream of its confluence with Beas River and the reservoir created, which form the Harike lake and the enlarged wetland, is a purposeful project, which acts as the headworks for irrigation and drinking water supplies, through the Ferozepur, Rajasthan and Makku feeder canals with total carrying capacity of , to supply to the command areas located in the states of Punjab and Rajasthan. The grand Indira Gandhi Canal in Rajasthan is fed from this source. The lake is triangular, with its apex in the west, bounded by a bund called the Dhussi Bund forming one side, a canal in the second and a major road on the third. The periphery of the lake is surrounded by agricultural land and the wetland is reported to be rich in ground water resources.

Water quality

The Punjab State Council for Science & Technology has reported that the water quality of the lake is mostly of 'A' Class as per the designated best use criteria even though large volumes of polluted water discharge into the wetland from industries and urban centres.

Biodiversity

The rich biodiversity of the wetland, with several species of birds, turtles, snakes, amphibians, fishes and invertebrates, is reportedly unique.

Bird sanctuary

The wetland was declared a bird sanctuary in 1982 and named as Harike Pattan Bird Sanctuary with an extended area of 8600 ha.http://www.toursandtravelsinindia.com/nationalpark/harike_pattan_sanctuary.html Harike Pattan Sanctuary Bombay Natural History Society (BNHS) carried out research and a bird ringing programme during the period 1980–85. An ornithological field laboratory was proposed to be established by BNHS.

200 species of birds visit the wetland during winter season of which some of the well known species (''some are pictured in the gallery'') are the cotton pygmy goose (''Nettapus coromandelianus''), tufted duck (''Aythya fuligula''), yellow-crowned woodpecker (''Dendrocopos mahrattensis''), yellow-eyed pigeon (''Columba eversmanni''), water cock (''Gallicrex cinerea''), Pallas's gull (''Ichthyaetus ichthyaetus''), brown-headed gull (''Chroicocephalus brunnicephalus''), black-headed gull (''Chroicocephalus ridibundus''), yellow-footed gull (''Larus michahellis''), Indian skimmer (''Rynchops albicollis''), white-winged tern (''Chlidonias leucopterus''), white-rumped vulture (''Gyps bengalensis''), hen harrier (''Circus cyaneus''), Eurasian tree sparrow (''Passer montanus''), hawk (subfamily Accipitrinae), Eurasian hobby (''Falco subbuteo''), horned grebe (''Podiceps auritus''), black-necked grebe (''Podiceps nigricollis''), great crested grebe (''Podiceps cristatus''), white-browed fantail (''Rhipidura aureola''), brown shrike (''Lanius cristatus''), common woodshrike (''Tephrodornis pondicerianus''), white-tailed stonechat (''Saxicola leucurus''), white-crowned penduline tit (''Remiz coronatus''), rufous-vented grass babbler (''Laticilla burnesii''), striated grassbird (''Megalurus palustris''), Cetti's warbler (''Cettia cetti''), sulphur-bellied warbler (''Phylloscopus griseolus'') and diving duck.

Vegetation

The wetland's rich floating vegetation comprises the following:

* ''Eichhornia crassipes'' sp. are sparsely seen in open water areas.
* ''Nelumbo nucifera'', the lotus, is the prominent rooted floating vegetation.
* ''Ipomoea aquatica'', is at the lake periphery in the shallower regions.
* ''Najas'', ''Hydrilla'', ''Ceratophyllum'', '' Potamogeton'', ''Vallisneria'' (eelgrass, tape grass vallis) and Charales are the species of submerged vegetation
* '' Typha'' sp. str the dominant emergent marsh vegetation.
* Tiny floating islets are formed by ''Eichhornia crassipes'', ''Acacia nilotica'', ''Zizyphus'' sp., ''Ficus'' sp., alien ''Prosopis juliflora'' in large clumps and other trees are planted along the embankment. The State Wildlife Department has constructed earthen mounds in the marsh area with trees planted on it to increase nesting sites for the birds.

Aqua fauna

Endangered turtles and smooth-coated otters, listed in the IUCN Red List of Threatened Animals, are found in the wetland.

26 species of fish are recorded which include rohu, catla, '' Puntius'', ''Cirrhina'', ''Channa'', ''Mystus'', ''Chitala chitala'', ''Cyprinus'', and ''Ambassis ranga''.

Invertebrates recorded are: molluscs (39 & 4 taxa), insects (6 & 32 taxa), crustaceans (27 taxa), annelids (7 taxa), nematodes (7 & 4 taxa), rotifers (59 & 13 taxa), and protozoans (5 & 21 taxa).

Indus dolphins

The Indus dolphin ('' Platanista gangetica minor'') supposed to have become extinct in India after 1930, but largely found in the Indus River system in Pakistan, was recently sighted in the Beas River in Harike wetland area. This aquatic mammal classified as an endangered species in the Red Data Book of the International Union for the Conservation of Nature and Natural Resources is considered a significant find. The dolphins were discovered by Basanta Rajkumar, IFS who was the officer in charge of the area while touring the area on a motorboat on the morning of 14 December 2007. Freshwater dolphin conservationist of the World Wildlife Fund India team, who were called in to help in surveying the area after the discovery, sighted a family of half a dozen dolphins at two different places along the 25-km stretch upstream of the Beas and thus confirmed the veracity of the claim made by the forest officials of the state government. An authority on freshwater dolphins with the endangered species management wing of the Wildlife Institute of India, Dehradun has also confirmed this finding. Discovering it in 2007, which was declared by the United Nations as Dolphin Year, was considered a special event. However, in the same Beas River, about 140 km downstream of the Harike Barrage in Pakistan territory, Indus dolphins are commonly found.

Gharials

The gharial (''Gavialis gangeticus'') was once found in great numbers in the Indus River system before its population dwindled and it is now classified as critically endangered in the International Union for Conservation of Nature's ( IUCN) Red List of Endangered Species. The Punjab Government is now planning to release 10 gharials in the Harike Wetlands as the first step to increase their numbers and to attract more tourists.

Wetland degradation

The wetland which is in existence since 1953 underwent changes over the years because of several factors, some of which are:

* Encroachments on the wetland habitat for intensive agriculture with resultant effluents of agricultural chemicals and also controversial encroachments.
* Utilization of surface and ground waters for irrigation
* Effluent discharge of untreated waste from towns and villages from industrial, urban and agricultural activities into the rivers which feed the wetland resulting in extensive weed growth (water hyacinth
