  • Biological and Environmental Condition of Salt Marsh Surrounded by a Sand Bar along Marginal Area of Tidal Flat

説明

A 600-m-longs and bar extends in Sanbyakkenr egion in Nakatsut idalf lat and a salt marsh has been developed behind this sand bar, forming the habitat for many kinds of lives.The relationship between the habitat conditions of animals and plants and tidal range in this salt marsh is investigated through the field observation. This salt marsh has such characteristics that it is protected from strong wave actions by sand bar, a gentle slope extends between+0.4m and 0.6m above HWL, and there has a large time lag in changes in tide level by the existence of the meandering channels, keeping the brackishe nvironment for a long time.To soundlypreserve a salt marsh, the conservation of the geomorphology with these characteristics is required.
