Abstract

The flora and fauna of mangrove forests in nine localities in Bachok, Kelantan were investigated from 16th to 19th June 2008. Though much of the mangroves have been reclaimed, remnant mangroves were found in the estuary of Semerak River. Nypa fruticans colonized the banks of the estuary, while Rhizophora apiculata dominated much of the upper shore. Elsewhere, there were small stands of Sonneratia alba, Avicennia marina and Bruguiera spp. The benthic fauna was dominated by 18 species of gastropods, 5 species of bivalves, 13 species of crustaceans (mostly sesarmine crabs), a sipuncula and 3 species of small fishes. East coast mangroves are estuarine in nature as they are located in sheltered situations, and thus not subjected to strong wave action or tidal currents. Accumulation of leaf litter on the forest floor seems to have encouraged high numbers of detritus feeding gastropod, Neritina violacea, to flourish in the high shore mangrove forest. Flora dan fauna hutan bakau telah dikaji di 9 lokasi di Bachok, Kelantan dari 16hb sehingga 19hb June 2008. Walaupun sebahagian besar hutan bakau dalam daerah Bachok telah musnah akibat diterokai, masih terdapat saki-baki hutan didapati di Kuala Sungai Semerak. Nypa fruticans dijumpai pada tebing kuala, manakala Rhizophora apiculata tumbuh di kawasan tinggi di hutan bakau tersebut. Di kawasan lain pada kuala tersebut, terdapat pokok lain seperti Sonneratia alba, Avicennia marina dan Bruguiera spp. Fauna bentik didominasi oleh 18 spesies gastropoda, 5 spesies bivalvia, 13 spesies krustacea (terutama ketam), sejenis sipuncula, dan 3 spesies ikan.kecil. Hutan bakau di pantai timur terletak di kawasan kuala yang terlindung, dari ombak kuat. Timbunan daundaun pada sediment hutan bakau telah menyebabkan bilangan gastropod Neritina violacea yang tinggi. Ia bergantung pada daun yang reput sebagai bahan makanan.
