Perhitungan Indeks Kesehatan Ekosistem Lamun (IKEL) yang meliputi variabel jumlah jenis lamun, persentase penutupan lamun, persentase penutupan makroalga, persentase penutupan epifit, dan kecerahan air menunjukkan bahwa di Pantai Blebak dan Pantai Ujung Piring berstatus buruk, sedangkan Pantai Semat berstatus sangat buruk.
