    An assessment of LGU-NGO-PO partnership in establishment of the Kalibo save the mangrove (Kasama) project in barangay
    Atienza, Aprille Danily C.; Quioyo, Chloe F. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2012-03)
    Fifteen (15) KASAMA members of the original beneficiaries of the Kalibo Save the Mangrove Project were interviewed for this study. The existence of poverty as a result of environmental degradation pushed the three main stakeholders, namely, the LGU of Kalibo, the USWAG Development Foundation, Inc., and the KASAMA Association to reforest 10 hectares of mangrove in the 1990s. The study seeks to evaluate the effectiveness of the project through livelihood development, people’s participation, and sustainable development. It also seeks to describe the factors that led to the partnership as well as the different issues and concerns of the stakeholders in managing the project. A survey and key informant interviews were conducted to gather the necessary data. Results show that there was no genuine organizing involved in the project implementation. Respondents and informants share their insights on project implementation and recommendations for its improvement

    Density of mangrove trees in selected municipalities in the Province of Antique, Panay Island, Philippines
    Arelis, Ian Jerwin C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2006-03)
    Mangroves line one quarter of the world’s tropical coastlines, and approximately 117 countries and territories have mangrove resources within their borders. Although over recent years mangrove deforestation has occurred at a phenomenal rate worldwide, constant assessment in the Philippines has been made to monitor its current status. To characterize the density of mangrove trees better in Panay Island, surveys were undertaken within the coastal and riverine estuaries in the 11 municipalities of the province of Antique. Detailed records were taken by transect and ocular surveys along 40 barangays with 75 transects and 223 plots established. The mangroves of Antique were composed of 31 species of true mangroves belonging to 14 families and a total of 16 generas. Considerable values in terms of relative density and stems per hectare were found with Nypa fruticans as the highest, with a relative density of 70.372% trees per hectare and an average stem density of 4,457.249 stems/ha. Other significant species included Sonneratia alba (4.534%; 625 stems/ha), Avicennia marina (4.524%; 1,525 stems/ha), and Rhizophora apiculata (4.232%; 50 stems/ha). Close examination of the data suggested the variability of distribution patterns and density to be attributable to the differing responses of individual species to the environmental factors and other human activities. It was also concluded that habitat classification and topography could directly affect mangrove distribution and also capable of altering basic zonation patterns.

    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.
