Front Cover
The picture is that of Interview Island in the Anda-mans chain as seen by the LISS III sensor of IRS-1D on 26 January 2000. The island (133 sq km) is covered with dense and evergreen tropical forests, and is bordered with coral reefs, sea grasses and seaweed patches. The dense red colour depicts healthy vegetation of the forest that is sensitive to the infrared channel of the LISS sensor. Cyan and light blue rims of the island depict coral reefs at different depths. Amongst the Indian coral reefs, the Andaman corals are the last refuge but they too are under severe threat due to human exploitation.
