All mangrove trees having a diameter at breast high (DBH) greater than 2.5 cm were tagged in two 20 x 20 m plot in stations SRS4-6 and TS/Ph-8. Measurements in PLot Num1 began in 1995; measurements in Plot Num 2 began in 2001. Plot Num1 in TS/Ph-8 was established in 2001. DBH has been measured in the period 1995-2004. Mangrove species include Rhizophora mangle. Laguncularia racemosa. Avicennia germinans. Conacarpus erectus. Sampling Description: The annual net increase in biomass will be estimated at different time intervals for each individual tree/species. The sum of these differences will represent the wood production for each site. The general objectives of this study are to evaluate differences in above ground productivity along soil P concentrations. soil salinity gradients. and hydroperiod. Information will be analyzed using a repeated-measures ANOVA. Two plots of 20 x 20m in each sampling station (only one in TS/Ph-8)Method Step - Description: An aluminum nail was placed at breast height (1.5 m) along with an numbered aluminum tag in each tree. DBH is measured above and below the nail at each sampling time; the mean value from these measurements is used for growth calculations. Tree height is measured using a calibrated range finder. accuracy of height measurements is plus or minus 3.5 m due to canopy density)Instrumentation: Standard DBH taperange finder Tree measurements in permanent plots Unit of abundance = IndCountInt, Unit of biomass = NA
