Sheet piles are unattractive for aquatic animals. They provide no shelter possibility, food or reproduction facility. Although the creation of habitats is highly important for species to survive, municipalities and contractors often fail to find te right solution, but with minimal efforts and a low extra investment these steel structures can contribute to a better ecosystem.

The initiative to stimulate biodiversity in the new urban district of Dordrecht by installing SPECTER is a great approach to enhance the ecological value of the area. Native swamp plants, also known as wetland plants or marsh plants, play a crucial role in supporting various forms of life and improving the overall ecosystem health. The plants filter the water, thereby improving the quality. Since this project has been a succes, more of these planters will be installed in the spring of 2024.
