Mount Merapi’s eruption has caused damage to the forests in the Mount Merapi National Park (MMNP). Nine years after the eruption, the vertical structure of vegetation can illustrate the progress of succession. This study aimed to analyze the tree composition and stratification in different forest damage levels after the 2010 Merapi eruption. The study was conducted in March 2019 at three stations, namely station A (heavy damage area), station B (moderate damage area), and station C (minor damage area). Vegetation parameters in each station were taken in a 10x100 plot and were processed using a tree profile diagram. Abiotic parameters were measured in each plot and analyzed using the correlation test. The results showed that the three stations were still dominated by the tree in Stratum C, but the tree density and tree height varied in proportion to the damage level. Station A in the heavy damage area has the lowest tree density (23 trees/0.1 ha) with a maximum tree height of 12 meters, in contrast to Station C in the minor damage area with tree density reaching 195 trees/0.1 ha and maximum tree height reaching 30 meters. Nine years after the Mount Merapi big eruption, the MMNP forests in Yogyakarta Province are still classified as young secondary forests. Key words: diagram, profile, succession, structure, vertical
The eruption of the most active volcano in Indonesia, Mount Merapi, has resulted in a very dynamic landscape as a form of ecosystem succession. This study aimed to analyze the carbon stock and vegetation composition in the secondary forest with variations in the level of disturbance after the 2010 eruption of Mount Merapi. Data collection was carried out in January 2020, in which biomass, necromass, and soil organic carbon data were taken in plot transect and Geographic Information Systems carbon stock products compared field data. The results showed that secondary forests at stations A and B with low and medium disturbance levels had carbon stocks in the high category. In contrast, station C at Cangkringan Resort, with high disturbance levels, still had carbon stock with a low category. Furthermore, the comparison of 2020 field data with GIS carbon stock products concluded a similar pattern between carbon stock from aboveground biomass WHRC 2010 and belowground biomass NASA 2010. This research concludes that the disturbance affected forest carbon stocks ten years after the 2010 Merapi eruption. Therefore, monitoring the vegetation community needs to be carried out annually through a combination of spatial and direct checks in the field.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
