Every plant species has its own way to survive. Some grow in a saline environment, many compete well with other plants. In the wadden region, you find habitats with extreme circumstances caused by natural forces such as wind, tides and salt. The plants have adapted to this difficult life. In sea, most plant life consists primarily of small free-floating algae: the phytoplankton. Plants such as seaweed and eelgrass can only grow in areas where a sufficient amount of sunlight is able to penetrate to the sea floor.
