Sands and Burrows Marshes are the last extensive areas of ungrazed saltmarsh on
the Lancashire coast. Linked in with the mudflats continuing all the way to Knott
End, the marshes are important for wintering waders and wildfowl and provide a
good day out for both the inexperienced and seasoned birdwatcher. Of
the waders, Redshank shares the mud with Knot, Snipe and Common Sandpiper. Wigeon,
Pink-footed Geese and Red-breasted Merganser are among the visiting wildfowl.
Cormorants are frequent visitors with Peregrines and Hen Harriers seen over the
marshes during the winter months. Skylark and Reed Bunting regularly breed on
the reserve. You might also hear the distinctive 'purr-weet' call of the Lapwing.
The
saltmarsh vegetation on both sites is made up of 'zones': lower or pioneer, middle
and upper zones. The lower marsh is dominated by Cord-grass, the spread of which
causes concern as it colonises open mud and areas of the marsh become pure Cord
Grass. Sea-purslane, Sea-blite and Saltmarsh-grass can be found in the middle
marsh. There isalso some Sea Lavender and Lax-flowered Sea-lavender, Sea Aster
and Sea Arrow-grass. This type of vegetation community is rare in Lancashire because
many of the species are rapidly eliminated by grazing. Upper sections of the marsh
include Thrift and Sea Purslane, but there is very little of this zone left because
of the sea wall built around the edge of the marsh. Arm
Hill, part of Barnaby's Sands, is a glacial drumlin composed of boulder clay and
covered with Gorse and acid grassland, providing a habitat for the rare Rock Sea-lavender
found at only three other sites in the county. The shingle bank formed from the
erosion of Arm Hill is home to Sea Wormwood, another rare plant. Management
Little practical management is required other than litter clearance. Photographic
monitoring records changes in the extent of saltmarsh.
