Coastal Wetlands

Coastal wetlands are along the coastlines of mid to high latitude areas worldwide. Coastal wetlands form near estuaries, the area where a river meets the sea, and are prone to varying levels of salinity and water levels because of tidal action. Because of the varying nature of these locations, most tidal wetlands consist of unvegetated mud and sand flats. Wetland types found in coastal watersheds include salt marshes, bottomland hardwood swamps, fresh marshes and mangrove swamps. Go to Coastal Wetland Reports

Mangrove Ecosystems

The Mangrove Ecosystems are distributed in the East and West coasts of India. Variously estimated to be the ranging from 5000 to 6810 Sq kms,the mangroves can be divided into three major types: These are: Tidal, Riverine and Lower Elevation Coastal swamps. A comprehensive information on mangroves of Orissa, Andhra Pradesh and Tamilnadu has been presented by the M.S. Swaminathan Research foundation ( Chennai. The information is in the form of an Atlas for each of the river basins of these states. In addition physico chemical, Geomorphology, hydrology, land use, flora, Socio economic variables, mangrove vegetation dynamics and shoreline and management imperatives have been provided.

T.V. RAMACHANDRA M.D. SUBASH CHANDRAN N.V. JOSHI BOOMINATHAN M. (April 2012).Status of Edible Bivalves of Central West Coast, Uttara Kannada District, Karnataka, India
Bivalves (Clams and oysters) contribute to the livelihoods of many people in India. Shell and sand mining in the molluscan beds, over-exploitation of bivalves, and sustained freshwater flows from the hydel projects are expected to have adverse consequences on estuarine bivalve resources. The present study was conducted in the four major estuaries of Uttara Kannada District (Kali, Gangavali, Aghanashini, and Sharavathi), to see the diversity of edible bivalves and their distribution. The study was conducted in 2011-2012 period in these estuaries. The status of edible bivalves of the estuaries was collected through primary observations and interviews with local fisher folks. Past studies were also referred to gather such information. Anadara granosa, Meretrix casta, M. meretrix, Paphia malabarica, Polymesoda erosa, Villorita cyprinoides and oysters were present in the Uttara Kannada estuaries. In Sharavathi estuary only Polymesoda erosa and oysters were found. The distribution zones of edible bivalves, and thereby their abundance, in the Kali estuary were less than the Aghanashini and Gangavali estuaries. The reasons for such disparity between the neighboring estuaries could be attributed to major human intervention in the form of construction of hydel projects upstream that caused low salinity conditions in the downstream causing depletion of most estuarine bivalves, as is glaringly evident in the Sharavathi estuary.

Major objectives of this project were (1) identify important marine turtle areas of Tamil Nadu (2) determine the nesting season (3) record the arrival and departure of nesting turtles and population estimate of each species (4) assess the rate and cause of mortality of different species with viable measures to reduce the mortality and (5) to assess the impact of mechanised and other marine fishing activities on turtles along the Tamil Nadu coast.
