Keanekaragaman Mangrove di Pantai Serambi Deli Kabupaten Deli Serdang Provinsi Sumatera Utara

Abstract

The existence of mangrove forests at Pantai Serambi Deli is an important area that plays a vital role for the region, functioning physically as a carbon sink, erosion barrier, windbreaker, and saltwater intrusion barrier, as well as biologically as a breeding ground for various organisms. Mangroves tend to form a density and structural diversity that acts as sediment traps and provides protection against coastal erosion. This research aims to assess the diversity and density of mangroves and the relationship between mangrove diversity and environmental parameters. The study was conducted from August to September 2024, which included sample collection and data analysis. he research findings show that there are 12 species of mangroves at Pantai Serambi Deli, namely: Achanthus ebracteatus, Nypa fruticans, Excoecaria agallocha, Xylocarpus granatum, Acrostichum aureum, Bruguiera cylindrica, Bruguiera gymnorrhiza, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, Avicennia marina, Avicennia officinalis, and Achanthus ebracteatus. The mangrove diversity index values at stations I, II, and III are 1.205, 1.683, and 2.151, which fall into the moderate category. The mangrove density values at the tree level are highest at station I with 2,300 ind/ha, the sapling level is highest at 8,400 ind/ha, and the seedling level is highest at 186,667 ind/ha. The relationship between mangrove diversity and environmental parameters shows a positive correlation.
