The
study was carried out as an intensive sampling survey in the intertidal
zones of Sarangani Province (Glan and Maasim), relying on the low tide
to determine the total species number, relative species abundances,
frequency and spatial distribution of seagrass.
Eight
Species of seagrasses andnineteen species of macroalgaewere gathered.
These have been the sampling sites of researchers, most especially
students, for its reputation of having diverse distribution of such
aquatic plants. A total of fifty sampling plots were laid using
quadrats; ten quadrats were arranged alternately with a five-meter
disparity between each plot, placed perpendicularly to the shore. The
study identified species of seagrass belonging to the family
Potamogetonaceae and Hydrocharitaceae. Nineteen species of macroalgae
were identified from where either seagrass was present or absent and
categorized under the family of Dasycladaceae, Ulvaceae, Halimedaceae,
Caulerpaceae, Dictyotaceae, Sargassaceae, Galaxauraceae,
Wurdemanniaceae, Gelidiaceae, Gracilariaceae and
Cryptonemiaceae.Seagrass.
Biodiversity indices such as dominance, Shannon’s diversity, evenness,
species richness and number of individuals were also determined using
PAST software. Distribution analysis revealed the three highest number
of species among the eightseagrass species wereEnhalusacoroides,
Haloduleuninervis and Thalassiahemprichii-such werecommon in both sites.
The Padina minor from the nineteen identified macroalgaespeciesin the
algal community has the most number of species. There are great
indications of seagrass and macroalgae presence with its distribution
when proper sampling procedure is done. Researchers strongly recommend
that physicochemical such salinity and sedimentation and also
correlation on distribution of species be studied further.
