Abstract

Over-exploitation and land-use conversion into aquaculture ponds have damaged the mangrove ecosystem. The extreme environment condition resulting in sedimentation led to the reduction of lagoon area and eventually of mangrove vegetation community. It was, therefore, necessary to conduct sustainable mangrove management through the monitoring system. Changes in the mangrove community were monitored periodically by evaluating width changes and land cover distribution. This study aimed to monitor the structure of mangrove community and changes occurring for the period of 2009 and 2015 by applying the purposive sampling method. The samples were mangrove vegetation community at several different locations. The samples were taken from nine stations with three replicates. There were 14 species of mangrove from six families. Mangrove trees were mostly found in the western area, while mangrove sapling and seedling mostly found in the east. Most of the stations showed a moderate level of diversity index and good productivity except station four. Mangrove forest in Segara Anakan had significant changes from 2009 up to 2015 due to the reduction of mangrove diversity.

Abstract

Increased carbon dioxide in the atmosphere causes global climate change seriously. Forests serve as an important asset that can absorb and store carbon in the form of biomass. One type of potential forest as a carbon sink is forests resin. The amount of carbon stored by standing very dynamic and varies according to the age of its standing. Therefore, studies will be needed to determine the effect of age on biomass and carbon stocks stands resin, determine the relationship between age and standing biomass and carbon stocks resin, and knowing the optimum resin stand age in storing biomass and carbon stocks. This research was conducted at the stands of resin RPH Karang Gandul, KPH Banyumas Timur for four weeks in May 2016. The method used is a survey with a sampling technique using cluster random sampling. Stands resin used in the study were classified into five age groups with 5 replicates. Data were analyzed using ANOVA with an error rate of 5% and continued with LSD for further test results were significant and regression analysis to determine the relationship of age with biomass and carbon stocks stands resin. The results showed that the age effect on biomass and carbon stocks stands resin, the relationship formed between the age of stand with biomass and carbon stocks are quadratic, and age optimum in storing biomass and carbon stocks is 35 years.
