ABSTRACT
This One Group study determined and compared the rate of biomass input that three mangrove species, namely, Avicennia, Rhizophora, and Sonneratia, contribute in the same habitat and in two different habitats – coastal and riverine. Using a contraption made of bamboo and fine nylon net, the biomass input of three mangrove trees of each species from each habitat were collected and even-dried weekly for a period of three months. The rate of biomass input in terms of grams dry weight per day was determined for each mangrove species. Using mean standard deviation as descriptive statistical tools and One Way ANOVA and paired t-test set at 0.05 alpha level of significance as inferential statistical tools, it was concluded that there is no significant difference in the rate of biomass input of three mangrove species in both the same and different habitats. This indicated that the three mangrove species contribute more or less the same amount of biomass input to the soil in both habitats.
