The dynamic coverage of coral reef habitat in Kapoposang Marine Tourism Park, Spermonde Island - Makassar Strait, Indonesia

Abstract

Around 20 percent of coral reef coverage and its high biodiversity in Spermonde Island has been declining in the last 12 years, where the dominant loss is the hard coral. However, only few studies use multi-scale accuracy methods to estimate the loss of hard corals in Kapoposang Marine Tourism Park. Hence, this study aims to map and analyze the dynamics of coral reef covers in Kapoposang Marine Tourism Park of Spermonde Islands for the past two decades (from 2000 to 2019). Data was obtained from the coral reef survey, to validate the Landsat imageries (TM dan ETM+), which were acquired and selected based on similar tides conditions. Gap fills on Landsat ETM+ are managed using Frame and Fill software, then analyzed using Lyzenga algorithm and validated with ground truth data. This study reveals that the coral reef coverage in Kapoposang Marine Tourism Park increased about 9,61% from 2000 to 2015, then declined about 7,41% from 2015 to 2019.
