(vii) Stand size/ fragmentation: Change in stand size/fragmentation in mangrove
vegetation have been mapped using multi-temporal temporal satellite data
(viii) Change in vegetation pattern: Changes such as mangrove to mangrove,
mangrove to halophyte, mangrove to non-mangroves were mapped using
multi-temporal satellite data.
(ix) Tree height: The average vegetation stand height is measured through field
observation using site-specific standard methods.
(x) Defoliation: Pre and Post-monsoon satellite data have been used to map the
defoliation including unseasonal shedding of Excoecaria agallocha and
