Description Kathuvallimuni Reef, a fringing reef of Palk Bay was surveyed for the assessr7.r,t of
the coral cover and biodiversity during January:May 2005, following the Line Intercept
Transect Method and their geographical positions were fixed using the Global Positioning
System. The percentages of live and dead coral cover at each site were derived. A total of
20 hard coral species were found on the transects; Plntypjm lai?lelliita was the major species
at 3 sites, followed by Porites solidlr, Favites virens, Hydnophora cxesa, H. microcoi~us, Tzirbinaria
mesenterinn, Anopora Izyacinthus and A. ~oymbosa at each of the 7 sites. The total live and
dead coral cover for t'he reef as a whole was estimated as 37.8% and 32.6% respectively and
the remaining part was covered with seagrasses, sand and rubble. Dead coral cover was
dominated by poritids. Further, relative abundance values were derived for each species and
they were assigned status as dominant/abundant/common/uncommon/rare. P.lamellina
belonged to the category "abundant" and all other species were either of "common" or
"uncommon" status only. The Shannon indices of diversity in most of the sites were moderate
varying from 1 to 2'and the reef as a whole showed a diversity of 2.8. The species richness
and evenness values showed values of 5.23 and 0.9 respectively.
