Coringa Wildlife Sanctuary is a wildlife sanctuary and estuary situated in Andhra Pradesh, India.[2][3] It is the second largest surviving stretch of mangrove forests in India with 24 mangrove tree species, and more than 120 bird species. It is home for the critically endangered white-backed vulture, and long billed vulture.[1]
Geography
Coringa Wildlife Sanctuary is 18 km from the port city Kakinada, on the Kakinada-Yanam state highway, nestling on the deltaic branches of Gouthami and Godavari Rivers at Kakinada Bay.[1]
It is located between 16°-30' to 17°-00' N latitudes and 82°-14' to 82°-23'E longitudes.[4]
The sanctuary is a part of the Godavari estuary and has extensive mangrove and dry deciduous tropical forest.[1]
About half of the area is the backwater, which include a sand pit of 18 km stretch. The rivers Coringa and Gaderu and their deltic branches intersect the region, along with other water channels. This forms about 335.7 square km of marsh vegetation.[1]
The average temperature of the region is 17 °C to 40 °C.[1]
Average Rainfall is greater than 1,000 mm.[1]
Flora
The Sanctuary in the estuary of river godavari has rich mangrove vegetation.[1][4] At present there are thirty five species of plants belonging to twenty four families.The plant species that are commonly found are:
Avicennia officinalis, Avicennia marina, Avicennia alba, Excoecaria agallocha, Rhizophora mucronata, Ceriops decandra, Bruguiera gymnorrhiza, Lumnitzera recemosa, Sonneratia apetala, Rhizophora conjugata, Aegiceras corniculatum, Thespesia populneoides and Hibiscus tiliaceus.[4]
Apart from the tree species, some of the shrubs found in the sanctuary are Dalbergia spinosa, Derris trifoliata. Herbs like Sesuvium portulacastrum, Suaeda maritima, Suaeda monoica and Salicornia brachiatta and grasses like Aeluropus lagopoides, Porteresia coarctate and Myriostachya wightiana are found in the sanctuary.[4]
Fauna
The sanctuary possesses a wide variety of birds, because of the feed available in the backwater of the mangrove forest. Particularly, during the low tide some of the areas are exposed (elevated mud flats having small fishes, shrimps, molluscs) attracting avifauna for its feed. Some critically endangered species like white-backed vulture, and long billed vulture are present in the sanctuary. The painted stork, Oriental white ibis, ferruginous pochard found in the sanctuary are near threatened spices, and spot-billed pelican is a vulnerable species. Significant populations of waders and mangrove birds are also present.[1] All together, more than 120 species of birds have been reported and among them some of the commonly found birds in the sanctuary are: little egret, cattle egret, pied kingfisher, small blue kingfisher, black-capped kingfisher, pond heron, reef heron, grey heron, night heron, little stint, sandpiper, redshank, red-wattled lapwing, crow pheasant, flamingos, sea gulls, purple heron, brahmini kite, openbill stork, and little cormorant.[4]
Apart from the avian fauna the sanctuary has a fair population of golden jackal, sea turtle, fishing cat, and a healthy breeding population of smooth-coated otter. The sanctuary has an 18-km long sand spit where olive ridley sea turtles nest from January to March every year.[1][4] Efforts to reintroduce the saltwater crocodile into the sanctuary during the 1970's were met with failure and the species has not been present within the sanctuary for over 30 years.
Threats and conservation issues
Despite being remote and difficult to access, the mangroves are being exploited by the local population. A socio-economic study by Indian Bird Conservation Network[1] found that most of local fishermen harvest wood in the forest and depend heavily on the mangroves for their basic needs. The species Avicennia officinalis, Avicennia marina are being used for fuelwood.[1]
The existence of otters has been hit badly because of increased poaching and habitat destruction. The increasing industrialisation of Godavari Delta, increasing aquaculture activities and fishing pressure have severely affected the population of otters. The Andhra Pradesh Forest Department has taken steps to ensure conservation of otters and for afforestation of mangroves in the sanctuary.[1]
