Floral diversity of a mangrove forest in Cotabato City, Philippines
Abstract
A variety of essential goods and services can be provided by mangrove ecosystem which has significant contribution to wellbeing and security of coastal communities. Hence, conservation measures to sustain this valuable resource should be of primary concern to all stakeholders. The present study was carried out to evaluate the floral diversity of a mangrove forest in Cotabato City. There were three sampling sites purposely selected for this study. A total of 12 sampling plots with a size of 5m x 40m each were established in the three study sites. Diversity indices were computed in each site. A total of 12 mangrove species representing 8 genus and 8 families were identified during the study period viz., Rhizophora apiculata, Rhizophora mucronata, Ceriops tagal, Lumnitzera racemose, Avicennia alba, Avicennia officinalis, Aegiceras corniculatum, Aegiceras floridum, Sonneratia alba, Sonneratia caseolaris, Xylocarpus granatum and Osbornia octodonta. Most of these species are classified as least concern. Species richness ranged from 0.77 to 1.04 while diversity index is generally low ranging from 1.19 to 2.02.
