Abstract

Litterfall is one of the important components that is taken into account in estimating primary productivity, especially to see its contribution to the estuarine ecosystem. The objective of the present study was to assess litterfall production rates of the Mangrove Forest in the Tourism Area of Pariaman City. Litterfall production in the study area was monitored from December 2021 - March 2022. The method used for litter collection is the litter-trap method. Sampling of mangrove litterfall were collected from 2 stations. Then, 6 litter-trap nets (Litter-trap) measuring 1x1 m2 were installed at each station which were randomly installed under the canopy of mangrove stands at a height of 1.5 m above ground level, so as to avoid the influence of tidal water. The litter production sample was then taken within 10 days for 6 times, the litter sample was then drying in air-circulation oven at 750C until constant weight was obtained. Then the litter mass was calculated within two months. The results of this study think that the average production in the Pariaman Mangrove Forest Tourism Park is 2.77 g/m2/day or 10.13 tons/ha/year with the order of the largest contributors being leaves > branches and twigs > generative organs.

Abstract

Mangrove ecosystems are located in coastal areas that are affected by the tides of sea. Mangrove forest acts as a green belt that protects the coast from erosion due to ocean waves or tsunami storms and traps sediments as accretionary activity. One of the processes that occur in the mangrove ecosystem that contributes the most to water fertility is the process of decomposition or destruction of mangrove litter. Litter destruction is part of the decomposition process stage that can produce important nutrients in the food chain through the productivity of the waters around the mangrove forest. The purpose of the study was to determine the rate of decomposition of mangrove litter in the Pariaman Mangrove Forest Tourism Park. This descriptive study was conducted from November 2021 -February 2022. This study used the litter-bag method to store leaf litter for which the rate of decomposition will be calculated. The results showed that the rate of decomposition based on the time of observation at the research station was different. At Station 1, the final dry weight value is smaller than Station 2 and Station 3, namely 0,26 gr/day at Station I, 0.9 gr/day at Station II, and 1,3 gr/day at Station 3.
