Floristic Diversity of Mangrove Restoration Area: A Case Study in Pasar Rawa, North Sumatra

Abstract

Mangrove forests are important ecosystems. However, land conversion and degradation have destroyed a significant area of mangrove. Mangrove restoration employing native species has been performed in several degraded areas, including some North Sumatra regions. However, information regarding floristic diversity in monoculture restoration areas is still limited. This research aims to analyze the floristic diversity in the mangrove restoration area, which is dominated by Soneratia alba species in Pasar Rawa Village, North Sumatra. The plotted path approach was employed for vegetation analysis in a 3-ha area in Pasar Rawa. The findings revealed that 8 (eight) species were found in the S. alba restoration area. The highest Important Value Index (IVI) in the seedling stage was found in Acanthus ilicifolius, while at the sapling and tree stages, S. alba was the highest. The highest diversity index was obtained at the sapling stage, which was 1.46 (medium), and the lowest was obtained at the tree stages, which were 0.26 (low). The result showed a new recruitment of seedlings in the research location, although the species diversity value is still lower. The appearance of new species, particularly pioneer species, in the research area indicates that natural succession processes are currently taking place.

Phytochemical Profile of Rhizophora apiculata, Bruguiera gymnorhiza, and Bruguiera cylindrica for Wood Identification

“…Currently, it is feared that the condition of mangrove forests in Indonesia will continue to decline from year to year, both qualitatively and quantitatively (Mutik et al 2022). This decline was due to illegal logging activities and the conversion of forest areas for various purposes such as plantations, agriculture, fisheries, industry, road infrastructure, ports, and settlements (Eddy et al 2019;Harefa et al 2024;Ikhsanudin et al 2018;Konom et al 2019;Luqman 2013;Narendra et al 2018). In illegal logging cases in court, identifying the wood species as evidence is always a priority that must be proven.…”
