Studying Mangroves

Water temperature was mensurable utilise a thermometer. The pH was determined exploitation a pH meter, and salinity was measured development the take hold TOGA refractors. Mangrove Damage and recovery Assessment The methods sedulous In this study were base from Roth (1992) and Taylor et al. (2013) with some modifications. In the island of Butting, seven 100 mm secret plans were established. The plots established were based on the vegetation types present. L. Species Composition All mangroves grow within the plots were recorded and Identified In slut. The handbook of Mangroves in the Philippines Panky by Primeval et al. 004) and Field put across to Philippine Mangroves excessively by Primeval (2009) were employ as principal resources in identifying the species. Mangroves were categorized into threesome trees, saplings, and seedlings. For Individuals having greater than or equal to 2. 5 CM spatter (girth at breast height, or 1. 3 m above ground level), they were categori zed as trees. GHB (CM) of each tree was measured using a measuring tape. For forking or ramify stems, measurement was done separately. For the seedlings and saplings, they were only identified and counted.Other observations, such(prenominal) as debris and abstract type, were also noted. II. Recovery Typhoon Impacts on the areas were recorded. Trees wealth the plots were Judged as dead or alive, and assigned to one of three structural tint categories standing, fallen, or snapped. The approximate height of breakage for snapped trees was also whether well reformatted, poorly reformatted, or dead were recorded. Ill. Regenerative capacity In assessing the regenerative capacity, the number of seedlings and saplings were monitored every month from February until April 2014. bear and dead plants were noted. Data AnalysesThe forest vegetation was evaluated using the following formula described by cathode-ray oscilloscopeton teal in 1984. Density was measured species fresh and total in each plot as follows Total slow-wittedness of all species = articulation of all species densities (2) Basal area was measured species wise and total in each plot as follows Basal area (mm) of each species = 0. 005 x DAB (7) Importance value of a species = relative density + relative dominance + relative frequency Species alteration was described according to the Shannon index (H) based on richness value of a species (N) and sum of importance value for all the species (N). H = NUN put down NUN (10)
