Abstract

The research was conducted in July - October 2020. Collection of data A. alba growth and abundance of benthic epifauna was carried out in the mangrove rehabilitated area of Kedabupat village, Kepulauan Meranti Regency. The aims of this study was to analyze the growth (stems height and diameter) of the mangrove A. alba species as a result of rehabilitation and abundance of benthic epifauna in the area. The method used in this research was a survey method, where data was obtained by directly to the research location. The data collected was data on the height and diameter of A. alba stems, density of macro epifauna species, and  water quality in the field, then followed by analysis of water and sediment samples in the laboratory. The results showed that the average increace in height of the stem by zone was 6.45-12.93 cm/month, meanwhile the average value of the increase in stem diameter by zone is 1.53-1.85 mm/month. There were 13 epifauna benthic species from 2 classes namely Gastropod and Malacostraca from mangrove rehabilitation. Gastropod class  that was Littoraria melanostoma, Nerita balteata and Sphaerassiminea miniata; from the malacostraca class that was Uca coarctata,  Metopograpsus latifrons, Ceonobita cavipes, and Clibanarius longitarsus. Benthic epifauna abundance values average ranged from 31.33-52.22 ind/m2.

Abstract

The research was conducted from July to December 2018 which aims to estimate the amount of carbon stock storage in wetland ecosystems that cover the near shore (mangrove) to upper land (peatland) in Sungai Tohor Village. Survey method was applied and sampling was done by non-destructive method that is without harvesting, so as not to change the ecological function of the forest. Data of carbon pool biomass was analysed and calculated in laboratory with allometric equations to extrapolate biomass. The results showed that the total carbon stock storage in the wetland ecosystem that covered the mangrove area to the peat area was equal to 51499.10 tons C / ha and was able to absorb CO2 by 70901.78 tons CO2/ ha. The largest total carbon deposits are in the mangrove region which is equal to 31525.83 tons C/ha, while the peat region has the ability to store lower carbon with a total value of 19973.27 tons C/ha.
