Berdasarkan pengamatana lapangan, kerapatan spesies tertinggi dimiliki oleh spesies Rhizophora mucronata, frekuensi spesies tertinggi dimiliki spesies S. alba, R. apiculata dan Rhizophora mucronata, penutupan spesies dan indeks nilai penting didapati spesies Sonneratia alba, Rhizophora apiculata dan R. mucronata..
