STRUKTUR KOMUNITAS LAMUN DI MALANG RAPAT, BINTAN

Padang lamun menyediakan banyak manfaat. Diperlukan penilaian tutupan lamun dan distribusi spasial spesies lamun, untuk memastikan manfaat dari padang lamun tetap ada. Penelitian ini dilakukan dengan metode kuadran disepanjang line transect, dan analisis data dilakukan untuk dapat menyajikan informasi tentang titik koordinat transek garis, persen tutupan lamun, persen tutupan spesies lamun, jenis substrat (pasir, lumpur dan pecahan karang), jumlah spesies Enhallus acoroides (tegakan/m2) dan distribusi spasial spesies lamun. Hasil penelitian menunjukkan kondisi padang lamun di wilayah studi sebagai kategori tutupan padat. Spesies lamun Thalassia hemprichii (Th) dan Enhalus acoroides (Ea) adalah spesies dominan dan menyebar ke seluruh wilayah penelitian.COMMUNITY STRUCTURE OF SEAGRASS IN MALANG RAPAT, BINTAN. Seagrass beds provide many benefits. Assessment of seagrass cover and spatial distribution of seagrass species is needed, to ensure the benefits of seagrass beds remain. The study was conducted using the quadratic method on the line transect, and the analysis was carried out to be able to present information about line transect coordinate points, percent cover of seagrass, percent cover of seagrass species, substrate type (sand, mud and rubble), number of species of Enhallus acoroides (shoot/m2) and spatial distribution of seagrass species. The results showed the condition of seagrass beds in the study area as a category of solid cover. Seagrass species Thalassia hemprichii (Th) and Enhalus acoroides (Ea) are dominant species and spread throughout the study area.
