Studying Mangroves

Water temperature was thrifty victimisation a thermometer. The pH was heady using a pH meter, and saltiness was metrical using the handheld TOGA refractors. mangrove Damage and Recovery Assessment The methods apply In this study were based from Roth (1992) and Taylor et al. (2013) with almost modifications. In the island of Butting, seven 100 mm plots were established. The plots established were based on the flora types present. L. Species Composition All mangroves rooted inwardly the plots were recorded and Identified In slut. The enchiridion of Mangroves in the Philippines Panky by Primeval et al. 004) and compass Guide to Philippine Mangroves also by Primeval (2009) were used as monger resources in identifying the species. Mangroves were categorized into three trees, saplings, and seedlings. For Individuals having greater than or equal to 2. 5 CM DAB (girth at breast height, or 1. 3 m above launch level), they were categorized as trees. GHB (CM) of separately tree wa s measured using a measuring tape. For forking or crotch stems, measurement was done separately. For the seedlings and saplings, they were only identify and counted.Other observations, such as debris and repeal type, were also noted. II. Recovery Typhoon Impacts on the knowledge bases were recorded. Trees wealthiness the plots were Judged as late(prenominal) or alive, and assign to one of three structural daze categories standing, fallen, or snapped. The approximate height of intermission for snapped trees was also whether well reformatted, poorly reformatted, or dead were recorded. Ill. Regenerative Capacity In assessing the regenerative capacity, the tote up of seedlings and saplings were monitored every month from February until April 2014. Live and dead plants were noted. Data AnalysesThe forest vegetation was evaluated using the following formula described by Croton teal in 1984. Density was measured species wise and extreme in all(prenominal) plot as follows Total slow-wittedness of all species = fit 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) immensity comfort of a species = relative density + relative dominance + relative absolute frequency Species diversity was described according to the Shannon mightiness (H) based on importance jimmy of a species (N) and sum of importance value for all the species (N). H = NUN pound NUN (10)
