Gibraltar Point

Martha Kearney explores the shifting sands of Gibraltar Point, on the Lincolnshire coast, to find out how beach-nesting birds are being protected.

Martha Kearney explores the shifting sands of Gibraltar Point on the Lincolnshire coast, to witness the effects of beach erosion on both birds and people.

At Gibraltar Point National Nature Reserve, wardens go to extraordinary lengths to protect shore-nesting birds from habitat loss caused by beach erosion. They build wooden platforms for the nests of little terns and cages to protect the nests of ringed plover, as well as mounting overnight patrols to keep predators away. In 2023 they tried the platform technique with oystercatchers for the first time, meticulously moving the nests in stages so as not to spook the birds. The shingle where these striking birds prefer to nest is threatened with inundation from high tides, as well as from foxes, sparrowhawks and curious humans with dogs. The birds raised a successful brood and now the wardens are preparing for another season, hoping for more fledgling oystercatchers.

Reserve wardens aren't the only people to take extraordinary measures to deal with beach erosion. The sand on Lincolnshire's beaches has to be replenished every year to protect the coastal population from flooding. Like sandcastles on an enormous scale, 400,000 cubic metres of sand are pumped onto the beaches from offshore dredgers and a sand profile created, in what's known as 'beach nourishment'. It's become a tourist attraction in its own right. The sand works its way a few miles down the coast to Gibraltar Point with the tides, literally shoring up the sea defences.

And then there are the inland pumping stations at every seaside town, which 'evacuate' water from low-lying areas, of which there are many in Lincolnshire: one third of the county is below sea level. Without them, this landscape would be marshland. Martha compares the historic diesel pumps (made in Lincoln) with the automated electric pumps (from Holland).
