Here is one of the Ellington Farm arable field subsidence
ponds in September 2013 (left) and this July (right). In 2013 the wide, shallow
pool had stayed wet most of the summer, the open water ideal for gulls, and
waders to loaf about leaving the water’s edge with a scum line of preened
feathers and down. It was ploughed
through in the autumn but then left unplanted and soon reverted to its less
domesticated state. In 2015 the pond was waterlogged over winter but only as a small
central pool and the winter wheat has been drilled, germinated and is fast approaching
harvesting. I doubt that any teal or avocets hung around this year. Since 2010
we’ve kept track of when these ponds dry and fill, and their changing areas.
The arable field ponds are particularly sensitive to the rainfall of the preceding
month, the ponds in amongst wetland mosaics and dune slacks less so, perhaps
buffered by a more waterlogged surround.
If the pond stays like this the whole lot can be
ploughed and planted this autumn, which may be enough to knock it out of the
wider pond-scape and banish the wildlife that likes these disturbed, open
flashes. The wall of wheat looks likely to advance, unless the weather turns fearsomely wet.
Druridge Bay, an eight mile arc of sand running north from Cresswell to the harbour of Amble in Northumberland, strewn with wetlands. From lagoons stained the deepest green by summer algae to flooded tyre ruts, glinting water in the arable fields. This blog is a snapshot of research at the University of Northumbria as we explore this pondscape forged between northern sea and sky.
