Carbon stock at several types of mangrove ecosystems in Bregasmalang, Central Java, Indonesia

Abstract. Sugiatmo, Poedjirahajoe E, Pudyatmoko S, Purwanto RH. 2023. Carbon stock at several types of mangrove ecosystems in Bregasmalang, Central Java, Indonesia. Biodiversitas 24: 182-191. Mangrove have an important role but are also faced with the conversion use and impacts from climate change. Therefore, this research aims to determine carbon above-ground, below-ground, soil Java. A total 8 transect lines, each having a length 125 m consisting six plots, were placed four obtain data on diameter vegetation five different depths. Allometric equations used analyze data, while compositions analyzed laboratory. The results showed that Bregasmalang was 713.13 Mg ha-1 details as follows; above-ground 30.27 (4%), below-ground 10.99 (2%), 671.87 (94%). Meanwhile, conservation forests 763.75 ha-1, rehabilitation 719.25 silvofishery 680.71 ponds 688.81 ha-1. Based results, high mangroves importance protecting mitigate
