Into the water with our ecologist Tijl Essens!

In this video interview, our ecologist Tijl Essens explains to Mara all about the special biodiversity around our Xstream blocs in the river IJssel in The Netherlands and see how fish and water plants use the space between our Xstream blocs. With these flexible groynes made of Xstream blocs we keep the river in place and we create space for biodiversity.
