    Banate Bay mangrove reforestation program: Prospective area for community-based property rights (CBPRs)
    Ungkakay, Farisal B. (Institute of Fisheries Policy and Development Studies, College of Fisheries and Ocean Sciences, University of the Philippines in the Visayas, 2004-03)
    The study focuses on the Mangrove Reforestation Program of the Banate Bay Resource Management Council, Inc. (BBRMCI), particularly in the 5 coastal barangays bordering Banate Bay, Iloilo, namely: Tiwi, Palaciauan, Pantalan, Belen and Talokgangan. It describes the processes, issues and prospects encountered by BBRMCI in the implementation of the mangrove reforestation project. Focus group discussion with key informants at the community, as well as interview of BBRMCI staff were done to capture the initiatives and mechanisms involved in the program, organizational arrangements in these areas and the issues the BBRMCI faces in the program implementation. It further explores the feasibility of transferring the management of such initiative to the local communities or communal groups in the area. A set of criteria was used to assess the capacity of existing organizations to assume management responsibilities for the mangrove resources. These are: presence of clearly defined boundaries for the resources, presence of a small user's group with mutual obligations and rules against defectors, an overlap between the location of the common property and organization or community member's residence, degree of dependence of the user group on the resource and support from local decision-makers. Although results show that most of the abovementioned criteria are present in the Barangay Fisheries and Aquatic Resources Management Councils (BFARMCs), conditions at the community level still, are not conducive for the transfer of management responsibilities to BFARMCs primarily because BFARMCs are considered as government-arms and not independent groups. Second, there is a need to define the level of importance of each of the 5 criteria to achieve the desired success of CBPRs. Other equally important features are therefore recommended, in addition to the criteria used, to increase the chances of success of the Mangrove Reforestation Program of BBRMCI. These are: (1) defining the user group's capacity; (2) system of sanctions and rewards within and outside a user group; and (3) presence of appropriate legal institutions that will allow exclusive use rights over the resources to qualified user groups.

    Community structure of a ten-year-old naturally, regenerating mangrove stand in Baguingin, Tigbauan, Iloilo
    Animas, Ruphil May J. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1999-04)
    The structure of the mangrove community in Baguingin, Tigbauan was studied using the transect line plot method with seven plots established. 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: Excoecaria agallocha, Avicennia marina, and Avicennia alba. A. marina was found to have the highest relative density of 70.8%. relative dominance of 52.35% and importance value of 169.82. A. marina and A. alba have equal relative frequency of 46.67%. Seedlings and saplings of A. marinadominate 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, Avicennia species and Excoecaria agallocha.

    Physiochemical factors affecting mangrove distribution and occurrence in selected sites in the Province of Antique
    Agapin, Antonio, Jr. D. (Division of Biological Sciences, Bachelor of Science in Biology, University of the Philippines Visayas, 2009-03)
    Mangrove forests are unique inter-tidal ecosystems comprised of taxonomically diverse, salt-tolerant tree and other plant species that are primarily found o.i relatively sheltered coastlines, deltas, estuaries, and lagoons in tropical and subtropical regions of the world. The objective of this study is to generally determine the physicochemical factors influencing the distribution and occurrence of mangroves in selected sites in the Province of Antique and to specifically measure selected physicochemical factors influencing the distribution and occurrence per species per municipality and correlate selected physicochemical factors like soil and water salinity, soil and water pH, and soil and water temperature influencing the distribution and occurrence per species per municipality using Pearson Correlation Coefficient. There were 224 plots established in 11 municipalities in the province of Antique. Twenty-five plots were established in Anini-y, 44 in Hamtic, 11 in San Jose, 5 in Belison, 18 in Patnongon, 23 in Bugasong, 11 in Barbaza, 9 in Tibiao, 26 in Culasi, 23 in Pandan, and 29 in Semirara. A total of 27 true mangrove species belonging to 12 families were found in the 11 municipalities of Antique. The 12 families are Family Avicenniaceae represented by Avicennia alba , Avicennia marina, Avicennia officinales, and Avicennia rumphiana', Family Combretaceae represented by Lumnitzera racemosa and Lumnitzera littorea; Family Euphorbiaceae represented by Excoecaria agallocha; Family Lythraceae represented by Pemphis acidula; Family Meliaceae represented by Xylocarpus granatum and Xylocarpus moluccensis; Family Myrsinaceae represented by Aegiceras coniculatum and Aegiceras floridum; Family Myrtaceae represented by Osbornia octodonta; Family Arecaeae (Palmae) represented by Nypa fruticans; Family Rhizophoraceae represented by Bruguiera cylindrica, Bruguiera gymnorrhiza, Bruguiera sexangula, Ceriops decandra, Ceriops tagal, Rhizophora apiculata, Rhizophora mucronata, and Rhizophora stylosa; Family Rubiaceae represented by Scyphiphora hydrophyllacea; Family Sonneratiaceae presented by Sonneratia alba, Sonneratia caseolaris, Sonneratia ovata; and Family Sterculiaceae represented by Heritiera littoralis. For Soil pH, the highest value of 8.87 was observed in the municipality of Hamtic and the lowest at 6.32 in the municipality of Semirara. Overall mean soil pH was 7.31. For Water pH, the highest value of 8.96 was observed in the municipality of San Jose, and the lowest value of 6.29 in the municipality of Tibiao. Overall mean water pH was 7.23. For salinity, it ranged from 3.1 ppt (Tibiao) to 27.47 (Semirara) and the overall mean was 13.37 ppt For Water Temperature, the highest value of 29.48 °C was observed in Anini-y & the lowest value of 24.74 °C in the municipality of Semirara with an overall mean of 27.40 °C. For Soil Temperature, the highest value of 30.2 °C was observed in the municipality of Belison & the lowest value of 24.97 °C in the municipality of Semirara with an overall mean of 27.50 °C. Among the species present, Aegiceras floridum showed significant correlation with Soil pH (favor low soil pH), water pH ( favor low water pH), salinity ( favor high salinity), soil temperature (favor high soil temperature) and water temperature (low water temperature), A. rumphiana showed significant correlation with water pH (favor low water pH) and soil temperature ( favor low soil temperature), B. cylindrica showed significant correlation with soil pH ( favor high soil pH), C. decandra showed significant correlation with water pH (favor low water pH) and salinity (favor high salinity), L. littorea showed significant correlation with soil pH (favor high soil pH), water pH (favor high water pH), salinity (favor high salinity), soil temperature (favor high soil temperature) and water temperature (favor high water temperature), O. octodonta showed significant correlation with soil pH (favor high soil pH), water pH (favor low water pH), salinity ( favor low salinity), soil temperature (favor high soil temperature) and water temperature (favor low water temperature), S. caseolaris showed significant correlation with water pH (favor low water pH), salinity (favor low salinity), soil temperature (favor low soil temperature) and water temperature (favor low water temperature) and S. ovata showed significant correlation with soil pH ( low soil pH), salinity (favor low salinity) and water temperature (favor low water temperature). Species like A. corniculatum, A. alba, A. marina, B. sexxangula, E agallocha, H. littoralis, L racemosa, N. fruticans, R apiculata, R mucronata, R stylosa, S. alba, X. granatum and X. moluccencis showed wide tolerance (no correlation) in all physicochemical factors (Soil Salinity, Water pH, Soil pH, Soil Temperature and Water Temperature).
