Community structure of a ten-year-old naturally regenerating mangrove stand in Baguingin, Tigbauan, Iloilo [Undergraduate thesis, University of the Philippines Visayas].

Community structure is described in terms of the following parameters: basal area, stems per hectare, relative density, relative frequency, relative dominance, and importance value of the species and the Shannon Index of Diversity. Variations in these parameters are correlated with certain physico-chemical factors-- air and water temperature, soil pH, water salinity, land elevation- and the degree of human influence. Three true mangrove species were found in the area: <i>Excoecaria agallocha, Avicennia marina, and Avicennia alba. A. marina</i> was found to have the highest relative density of 70.8%. relative dominance of 52.35% and importance value of 169.82.<i> A. marina</i> and <i>A. alba</i> have equal relative frequency of 46.67%. Seedlings and saplings of <i>A. marina</i>dominate the area, indicating that the community is a young and regenerating stand. Basal area significantly increased from sea to land ( 53.68 cm2 to 431.66 cm2) and from creek to land ( 8.83 cm2 to 366.54 cm2). Shannon Index of Diversity gave a result of 0. The very low diversity index means that there is uneven distribution of individual trees among the species, and only a few kinds of species were present and are centered around only two genera,<i> Avicennia</i> species and <i>Excoecaria agallocha.</i>iv, 46 p.MangroveRegenerating mangroveMangrove communityMangrove community sturctureNaturally regenerating mangroveLG 993.5 1999 B4 A556Thesismangrovesregenerationmangrove restorationSDG 14 - Life below waterSDG 11 - Sustainable cities and communities
