followed by Great Nicobar (524 ha), Kamorta and Nancowry (192 ha) and Trinket
(117 ha). The loss of mangrove cover continued and it was assessed to be 914 ha be-
tween 2005 and 2007. Maximum loss was in Kamorta and Nancowry (581 ha) fol-
lowed by Trinket (117 ha). In other islands, most of the mangrove area had already
been destroyed earlier. In Great Nicobar and Little Nicobar, there are no discernible
mangrove left. Total loss of mangrove cover between 2003 and 2007 is estimated at
2414 ha. Now only 3 km 2 (300 ha) of mangrove cover is left in Nicobar compared
with 27 km 2 (2700 ha) existing in pre-tsunami period.
Remote sensing-based rapid assessments done by FSI ( 2006 ), Ramachandran
et al. ( 2005 ) and Sridhar et al. (2005) show significant damage in forest and man-
grove areas of Nicobar Islands, but these studies are based on comparison of satellite
data of the pre-tsunami period with the images of immediate post-tsunami. Rapid
