Description 1391-1400
Present
study infers that the construction of embarkation wharves in four of the
Lakshadweep islands (Agatti, Amini, Kavaratti and Minicoy) in the last 5 years
was accompanied by a marked degradation of coral community structure and coral
biodiversity. Reduction in live coral percent cover was significant, from 31%
to 4.69% in Agatti, 24% to 5.92% in Minicoy, 22% to 3.49% in Amini and 30.5% to
4.4% in Kavaratti, with a simultaneous rise in the percent cover of other
abiotic components. Species diversity of corals dominated by the massive
reef-building corals was lost, affecting the structure and stability of the
reef at these sites. Resilience potential of the reef became poor due to the
monospecific colonization of corals belonging to very few genera like Pocillopora and Montipora. Reduction in coral cover and its diversity endangered
the strength of the reef frame in the activity site and enhanced its
vulnerability to the natural stress or calamities.
