Abstract

A comparative study was undertaken of the fate of fine sediment in the Ngerikiil and Ngerdorch mangrove-fringed estuaries in Babeldaob Island, Palau, Micronesia, in 2002. The mangroves comprised 3.8% of each catchment area, and in both systems, they trapped about 30% of the riverine sediment. Mangroves are important buffers protecting fringing coral reefs from excessive sedimentation. The sediment yield was significantly higher in the Ngerikiil River catchment (150 tons km−2 yr−1) that has been extensively cleared and farmed, than in Ngerdorch River catchment (1.9 tons km−2 yr−1) that was still relatively pristine during the study period.
