Sedimentation is one of the biggest threats facing coral reefs. Due to Palau’s largest island of Babeldaob’s steep topography, high rainfall, and highly erodible volcanic soil, erosion has been exacerbated by recent increases in land-use. Studies have documented the negative impacts of the resulting sedimentation on coral reefs around Babeldaob. Similar studies have shown that mangroves can trap about 30 % of the fine eroded sediment from land. This paper documents the filtering effects of cultivated wetland, namely that of taro (Colocasia esculenta) fields. The results showed that the taro fields have the capacity to trap up to 90 % of sediments.
