- Sandbach Flashes
Sandbach Flashes (gbmapping|SJ725594) is a
wetlandwest of Sandbachin Cheshire, England. The flashes were designated as a Site of Special Scientific Interestin 1963, with a total area of 1.53 km². There are a number of individual flashes including Fodens Flash and Elton Flashes.
Part of the site is managed by the Sandbach Flashes Joint Management Committee.
Description of site
Sandbach Flashes consists of a series of pools formed as a result of
subsidencedue to the solutionof underlying salt deposits. The water varies from freshwater, chemically similar to other Cheshire meres, to highly saline. Most of the flashes are surrounded by semi-improved or improved grassland. Fodens Flash is partly surrounded by wet woodland.
Inland saline habitats such as those present at Sandbach Flashes are extremely rare in Britain and support unusual communities of plants and animals.
Due to the differing age, depth, and water chemistry, the flashes show considerable variation in their plant and animal communities. The most recently formed have narrow disjunct stands of emergent vegetation dominated by Great Reedmace "Typha latifolia" and occasionally by Lesser Pond-sedge "Carex acutiformis", whilst the oldest have extensive stands of
Common Reed"Phragmites australis". At Fodens Flash the emergent vegetation grades into fenand wet woodlanddominated by Alder"Alnus glutinosa" and willow"Salix" spp. Wood small-reed Calamagrostis epigejos is locally dominant in the ground flora here.
In some areas
periodic floodingoccurs and species such as Water-pepper"Polygonum hydropiper", Plicate Sweet-grass"Glyceria plicata" and Celery-leaved Water-crowfoot"Ranunculus sceleratus" occur. Shore-weed"Littorella uniflora", a rare plant in Cheshire, is also present.
The more saline flashes are fed by natural brine springs and contain a range of species tolerant of
brackishwater, for example, Spiked Water-milfoil"Myriophyllum spicatum", Fennel-leaved Pondweed "Potamogeton pectinatus" and Horned Pondweed"Zannichellia palustris" and the green alga" Enteromorpha intestinalis".
Adjacent to these saline flashes are areas of saltmarsh vegetation containing species such as
Sea Aster"Aster tripolium", Lesser Sea-spurrey"Spergularia marina" and Reflexed Saltmarsh-grass"Puccinellia distans".
A number of uncommon
aquatic invertebrates occur including the mayfly" Caenis robusta" and the snail" Gyraulis laevis", and species associated with brackish water habitats including the water boatmen" Sigara concinna" and "S. stagnalis" and the shrimps " Gammarus duebeni" and "G. tigrinus".
The woodland at Fodens Flash has a rich
