Mangrove wetlands of Tamil Nadu, Andhra Pradesh and Orissa - Atlas by MSSRF

Mangrove1These state-wise atlases on mangrove wetlands were prepared by the M S Swaminathan Research Foundation (MSSRF) under the India-Canada Environment Facility supported project entitled “Coastal Wetlands: Mangrove Conservation and Management”.

The MSSRF project on fostering the sustainable management of mangrove wetlands in the states of Tamil Nadu, Andhra Pradesh and Orissa had yielded valuable results on the quantitative and qualitative aspects of mangrove wetlands with particular reference to the impact of anthropogenic pressures on the ecosystem on the one hand, and the benefits arising from eco-restoration and mangrove rehabilitation programmes on the other. The data have been compiled in the form of GIS maps which have formed the basis for a series of Atlases.
