Kekurangan Indeks dan Arahan Pengembangannya

116 6 Penilaian tingkat resiliensi suatu terumbu karang membutuhkan sejumlah transek yang dapat mewakili kondisi umum terumbu karang tersebut, sedangkan pengukuran indeks dilakukan pada setiap transek.

7.2 Saran-saran

1 Kabupaten Natuna dan Wakatobi perlu mendapatkan prioritas di dalam program pengelolaan terumbu karang nasional, karena memiliki terumbu karang dengan indeks resiliensi yang tinggi dan batas kedalaman pertumbuhan karang yang dalam.. 2 Penggunaan indeks resiliensi di dalam pengelolaan terumbu karang perlu dilengkapi dengan penilaian faktor batas kedalaman maksimal pertumbuhan karang. Faktor batas kedalaman tersebut untuk melengkapi penilaian kondisi terumbu karang, sehingga dapat dibedakan terumbu karang yang memiliki nilai konservasi tinggi dan rendah. 3 Pemantauan terumbu karang yang menggunakan metode selain transek garis perlu menyediakan data tentang ukuran setiap koloni karang, tutupan pasir dan lumpur, selain data yang sudah baku yaitu data tutupan karang dalam 13 kategori bentuk tumbuh kelompok fungsional, tutupan total algae, dan fauna lain. Dengan penyesuaian data tersebut, maka resiliensi terumbu karang dapat dinilai dengan menggunakan indeks resiliensi terumbu karang. 4 Pengukuran potensi rekruitmen karang CSN yang lebih akurat tetapi praktis diperlukan di dalam penggunaan indeks resiliensi terumbu karang. 5 Penggunaan indeks ini secara global masih perlu diuji, terutama dengan data dari terumbu karang Filipina yang memiliki keanekaragaman hayati sama tingginya dengan Indonesia. 6 Penggunaan indeks resiliensi untuk memprediksi pemulihan terumbu karang perlu dikembangkan lebih lanjut dengan jumlah cuplikan yang lebih banyak. 117 DAFTAR PUSTAKA Adjeroud M et al.. 2009.
