A general view of the Saltmarsh. A closer view would soon show a sward of Sea Pink coming into flower. the picture below shows Sea ink (Armeria maritima), Sea Milkwort (Glaux maritima) forming a ground cover. It was flowering over much of the marsh.
Glaux maritma now called (Lysimachia maritima) is a Saltmarsh specialist. it does not have petals the pink petals are sepals. On close up the leaves are dotted with pores, perhaps this is an adaptation to life in a saline environment.
The salty environment also suits Sea Arrowgrass (Triglochin palustris) coming into flower as spikes through the linear furrowed leaves. It was growing abundantly in the lower marsh.
Saltmarsh Grass (Puccinellia maritima) well fitted to its position in the lower marsh.
Another resident of upper and middle marsh, Common Scurvygrass (Cochlearia officinalis), struggling with bramble and grass.
For comparison, this is, surprisingly, Pyrennean Scurvygrass (Cochlearia pyrenaica). Why is it here since it often grows near old metal mine workings?
The water bubbling up here in the middle of the Seaton Burn is from old colliery workings and is polluted by various metals. This environment might be tolerable for C pyrenaica.
Sea Lavender (Limonium vulgare) likes the muddy banks but not in flower yet.
Alongside this is Hastate Orache (Atriplex hastata) also growing in the lower marsh.
Further up this Thistle is incredibly prickly, could be a Spear thistle but not typical.
Fine leaved Water Dropwort (Oenanthe aquatica) grows further up by a freshwater marsh where Bulrush (Typha Latifolia) had been planted in an attempt to clean the polluted water.
Ditches have been dug in linear trenche. Filled with fresh water, this habitat was ideal for tadpoles and algae.
False Fox Sedge (Carex otrubae) growing further up the Fresh water marsh.
Birdsfoot trefoil growing near the marsh on sandy soil.
Holywell Dene, an ancient semi-natural woodland, has a bluebell area. These bluebells do not look like wild type, however.
There was much else of interest on the way.
Black headed gull
Knotted clover (Trifolium stiatum) below.
Mosses crop up everywhere even on dry walls. This might be Common Beard Moss?
The flower below was unknown to me. It was in a roadside flower bed and is a cultivated bulb plant. It is White Star of Bethlehem (Ornithogalum umbellatum).
