The river Coquet is a desinated SSSI. In the saltmarsh you will find towards the front, Red Fescue grass (Restuca rubra), while closer to the sea, Saltmarsh Grass (Puccinallia maritima) dominates. Cord Grass (Spartina anglica) grows near the sea edge. The grass is frequently grazed by geese and swans, giving it a distinctive appearance.
Among the grasses, you'll come across small red-leaved humps of Sea Pink (Armeria maritima), Sea Milkwort (Glaux maritima), Sea Aster (Aster tripolium), and Sea Plantain (Plantago maritima). In June, Common Scurvy Grass (Cochlearia officinalis) is in flower, adding touches of pinks and whites to the marsh. Further along the Coquet estuary, you can discover Sea Purslane.
