In August a new type of Hillblocks are placed on the dikes around Burghsluis to promote ecology. The blocks have a coarser structure that can hold the water in and around the concrete column for a longer period. The semi wet structure provides a good breeding ground for different types of algae and tiny sea creatures. After two months, the first results are already visible on and between the blocks. On the blocks we find a layer of Blidingia Minima. Between the blocks a variety of brown algae has rooted, for example Vesicles Wrack, Flat Wrack and Knotted Wrack. Also the local fauna has found its way to the new revetment. On the blocks we already see a small colony of Acorn Barnacles and several periwinkles found their new home between the blocks.
