Up and down the Stangate Strip

During the winter months a rising spring tide from the Chetney sea wall provides one of the best wader spectacles on the estuary. Make the walk out from Raspberry Hill to close where the path cuts east over the Peninsula, and watch towards Slaughterhouse Point. As the waters keep rising to cover the neap roost sites, more and more lines of birds head past you towards Barksore saltings. At first, small groups of Grey Plovers, Godwits, Curlews- then a procession, chains of waders large and small coming off of Greenborough, Burntwick and the Chetney saltings. As the tide tops, large flights of Oystercatcher and Curlew may take to the sky just north of you, joined by big numbers of Lapwing, sometimes pulling the Golden Plover up with them. From then until the safer roosts uncover, wheeling flights of aerial roosters keep tripping overhead. All the excitement of the Stangate Creek complex- without actually viewing very much of Stangate Creek.

Historically, for the birdwatcher Stangate has always been difficult to view from land. Certainly there's a distant sight-line from the right lay-by at Funton, while further away, the panorama from up on the Saxon Shore Way, but as most birders are not content with counting specks these days, few bother (40 months back, still not bumped into a birder up on Tiptree Hill). Searching the various local birding guides very few authors have touched on the importance of the creek.




Starting from the mouth, working clockwise, the eastern flats opposite Burntwick, Sharfleet Creek and the north-east corner of Greenborough run into an unnamed (on the charts I have seen at least) large serpentine creek (A) that cuts into Chetney marshes for nearly a kilometre from low mark to seawall. For my purposes I've called it Chetney Creek (but if anyone can put me right...).

From the angles available up on Tiptree Hill the Creek appears to be a pool. It certainly has a good deal of standing water nearby in the form of dykes and reed-fringed fleets. Flights of duck are up and about as the raptors pass over.

On low waters, many resting wildfowl mainly line these flats, while the majority of the 'local' waders will have moved just north and east along the main channel by Blackstakes (B). Come the rise a number, of these waders move into Chetney Creek, more with any northern/eastern element to the wind. Many Shelduck and geese (wild and feral) will be either side of the wall here throughout the tidal cycle.

As you continue south south relatively little mud is exposed until you reach (the impressively named) Chetney Hill, The old Blackstump Creek (C) is still in good shape and is used by many birds over the tide, even though the sea wall has cut the creek off. Some excellent habitat around the Creek has been further improved with a pool/scrape, sadly obscured from the Chetney footpath (yellow) but is viewable, distantly, from the Saxon Shore way on Tiptree Hill.

The low mound of Chetney Hill is made into a round island by the Chetney canal that surrounds it. To the south and east the canal holds few birds at roost (due in part to the proximity of the public footpath and farm buildings), but the west and north are relatively undisturbed over the tide. The western edge is the site of the Oystercatcher roost birders can scan from the lay-by on the Funton road. Loafing Brent often use the roost (with birds still using it now in Mid-May). The late winter Knot flock, which more usually favour Greenborough or Chetney Creek, sometimes crams itself on here; this past winter the Knot actually usurped the Oystercatchers for a while, who retreated en masse to the old dock by the footpath.

(For any local historians, there is also the interesting story of the Chetney Hill Lazaret.)

Stangate Creek now has a dog-leg to the west. This borders the eastern end of Barksore (G), which has a remnant area of saltings now mainly covered by spartina; larger waders like Curlew can retreat here during a spring tide, and many Little Egret and Grey Heron will also gather, but the biggest numbers are now found at the end of Stangate; on our clockwise journey we now swing north onto Greenborough at the three-way junction with Millfordhope and Halstow Creeks (H) a substantial pre-roost gathering of waders and wildfowl builds, which can hold out spread along the old sea wall as far as Slaughterhouse point on a neap. This is an important shelter when certain winds, or disturbance, hit the Funton complex, and is where some/all of the 'Funton' Avocets will usually be found when reported as 'missing' from their main roost.

For the remaining journey back north out of Stangate Creek the western sea walls are covered by gulleries in the summer months. In winter, many waders are spread along the same walls. On the low tide these birds move, in the main, west to the larger flats such as Ham Ooze. As far up as Sharfleet Creek (I) resting duck and especially Geese will be sat on the western mudflats. The Greenborough shoreline is the more routinely fowled, when the birds drop east to Chetney. It is a similar usage picture for Sharfleet Saltings (J) and on up to the mouth at Stangate Spit (K).

That is Stangate circumvented; within that outline, the waters of the creek keep a good depth over the low tide period, and can be a magnet for birds. In winters when a local notable such as, say, a Long-tailed Duck or Common Scoter take up residence, over the high tide they try to keep to a good feeding depth of water, so move into Funton or Halstow with the tide, but then back out into Stangate on the drop. Any number of Goldeneyes and Mergansers present will follow the same routine, as do the smaller Grebes and the odd Diver. Stangate is a safer haven than the wide open waters of the main river channel along Saltpan Reach.

(An aside. I still deliberately remain on land for my birding; the various boat excursions for bird/seal watching nearly always end up in Stangate Creek, invariably turning up a good record or two around there. The birders that travel out on them swear by them. Whilst I can't personally vouch for any, a trawl around Queenborough quayside, Riverside Country Park {and even the 'floating tea room' at Lower Halstow} will find details of several different owners offering sailings.)

So, that's birds around Stangate, birds on Stangate, and now birds over Stangate. The mouth of the Stangate is the preferred arrival/departure for many of the breeding Terns that, in the main, prefer to head out to the open waters of the Greater Thames to fish. The southern end of the creek is directly below the flight-paths from Millfordhope/Halstow for waders/wildfowl en route to safe roosts. All the time birds are switching east to west to east over the rest of the creek. When breeding, the gulls routinely follow Stangate out south for feeding, or simply 'hop over' onto the Chetney fields to loaf/feed. The Marshes here are also used, pre-breeding, as gathering sites for returning birds, a time when counts of Mediterranean Gulls can reach three figures just inside the Creek.

Human usage is, in the main, as an overnight mooring for small craft during the summer months, mainly along the western edge of the deep water channel. More than a dozen boats can be anchored at a busy weekend, in the main seen as little threat by the roosters/nesters (it is the smaller craft, sailing close to colonies on the high tide, that cause most disturbance (landings are mainly limited to the unsigned Burntwick island, but most going ashore soon realise not to go near the colonies).

Of course, this guide is for the benefit of anyone seeing the seaplane playing on the 'runway' designated by Peel Ports; it is easy to appreciate the disturbance caused when on the strip, but disturbance to birds alongside, beyond the seawall as the plane banks low will be apparent to any observer.

One lives in hope Peel Ports may yet see the problems for this internationally protected and internationally important area.

I've been told not all comments are publishing. There seems to be a problem between Blogger and Chrome, and I'm being told if you have a problem you should try a different search engine.

All a pain in the proverbial. Sorry! I'm a luddite/technophobe (still won't even have a mobile phone) so much else is beyond me..

If still doesn't work, pls send me a DM/post to my twitter a/c @dunnokev to let me know- thanks! Kev 18/12/21
