Abstract

The mangrove ecosystem in Pangarengan Village, Cirebon District, provides benefits for environmental services, including as carbon sinks and stores. In estimating the carbon storage of mangrove forests, in general, allometric equations are used. Unfortunately, the allometric equations currently available are still composed of the stages of growth of saplings, poles, and trees. Thus, the purpose of this study was to develop an allometric model for seedlings in mangrove forests. The research was conducted in June 2021 in the mangrove forest of Pangarengan Village, Cirebon District. The equipment that used in the study were calipers, measuring tape, digital scales, and crop shears. Research materials were mangrove seedlings of Rhizophora mucronata, Avicennia marina, and Sonneratia caseolaris. The best allometric model in estimating dried weight biomass with base diameter predictor is Y = 35,013 Dp1,860 (R2adj = 0,873; SEE = 0,472) using tip diameter predictor is Y = 249.573 Du2,276 (R2adj = 0,524; SEE = 0,710). While the allometrics for estimating the carbon content of seedlings were Y = 5,835 Dp1,804 (R2adj = 0,831; SEE = 0,528) and Y = 35,750 Du2,107 (R2adj = 0,607; SEE = 0,805). Thus, the power allometric model with base diameter predictor was quite good in estimating dried weight biomass and seedling carbon content in the mangrove forest of Pangarengan Village.

Abstract

A special-purpose forest area (KHDTK) is the forest area which the purposes are for teaching and research activities. One of the research conducted in KHDTK Wanagama was examining the planting of superior Teak from breeding (jati Mega). The growth of clonal teak data can also be assessed for its carbon stock. Hence, the purpose of this research was to determine the potential of biomass and carbon stock in the Jati Mega stands at KHDTK Wanagama, Yogyakarta. The research was carried out using a non-destructive method which used the allometric equation Bt = 0.0149(D2.H)1.0855. Carbon value was calculated as 50% of the total biomass. The results showed that after 17 years of planting Jati Mega, the stand density was 665 trees/ha, carbon storage was 59.98 Mg C/ha, and carbon uptake was 220.11 Mg/ha (CO2-eq). The total value of biomass, carbon stock, and carbon dioxide removal by Jati Mega stands at KHDTK Wanagama was in the medium category. The advantage of this research is for understanding the environmental services of jati Mega as a forest carbon stock. Information on forest carbon stock can be used as basic data for forest management as climate change mitigation.Keywords: superior teak, climate change mitigation, carbon accounting, environmental services
