“…Marram grass can grow along with depositions of up to 1 m/y due to its layered root system and is thus an effective bio-builder. A burial rate of 30 cm per season provides the ideal circumstances for marram grass to grow, with a maximum of 80-100 cm per year (Nolet, 2021). Marram grass is vulnerable to saltwater intrusion and therefore occurs mostly at the upper beach and foredune zone (Van Dieren, 1934;Klijn, 1981), where new seedlings cluster around the deposition tails of grown, half-buried versions (Figure 3.45).…”
