Crossing the Humber

There have been several ferry crossings at the Humber at least since Roman times (including Winteringham to Brough, North to South Ferriby, Barton to Hessle, Hull to Grimsby, New Holland to Hull). Despite this, all ferry crossings stopped across the Humber when the Humber Bridge was opened in 1981. Today we cross the Humber Bridge and back. We start at Humber Bridge Country park, where there is a large free car park. It is a beautiful day, a light mist and light NE breeze but mainly sunny. The tide is almost low. The path is well signed from the country park and we join the west path for the crossing.
 You climb some stairs (or take a ramp) to join the bridge. Soon the views are stunning over the wooded country park and the across the estuary.

 The Humber is quite flat, slowly ebbing. The Humber Bridge is 2,220 m long. It doesn't take long to cross, and on a day like this is a wonderful walk.

There is a fair number of walkers and cyclists doing the crossing today. As we approach the south bank there are great views of Far Ings and we walk high over a pasture where cows are feeding almost like an aerial view.

We take the stairs down, walk under the bridge and follow a right of way path by a mature hedgerow and some clay pits. A Hairy Dragonfly patrols over one of the pools, covered in patches of flowering water crowfoot.

 After a short walk on the foreshore of Far Ings we go for lunch at the Old Tile Works, which has great views of the bridge.

After lunch is time to the back crossing, this time on the east side of the bridge. The tide is almost completely low now, exposing a very wide mudflats and the salt marsh by Water's Edge Country park.
Some sand banks are exposed in the middle of the Humber. It is quite warm now and the breeze quite welcome. We point at salient features of the city of Hull: the P&O Ferries, the Hospital, Reckitt's chimney, the KC stadium and Arco.
We descent the steps onto the country park and go down to Hessle foreshore for coffee and ice cream. A great family day out, and the first time all of us walk the Humber Bridge.

A start for the Yorkshire Dragonfly quest at Oak Road Lake

 I am hoping to see and photograph all 25 breeding dragonfly species in Yorkshire this year. On the 7th of May I had a glimpse of a dragonfly, the first of the year, likely a four-spotted chaser, at North Cliffe Wood, but I didn't relocate it and there was no photo so I won't count it. I wasn't expecting much this windy, sunny and warm afternoon but I had a very pleasant surprise when I saw a Hairy Dragonfly (sp 1) patrolling up and down the edge of the wood by Oak Road Lake. It finally settled in a sheltered corner. To my knowledge, this early emerging species hasn't been recorded at Oak Road Lake, but it appears to be expanding in East Yorkshire.
 A Blue-tailed Damselfly (sp. 2) was resting in the north side of the lake.
 There were several damselflies over the water, including a male Common Blue Damselfly (sp 3)...
 ...and several Large Red-eyed Damselflies (sp. 4). They were far out over the water, including a pair in tandem, but I managed some record shots.

Walking the Humber. Stage 14. Skeffling Clough to Kilnsea

I park at Sammy's point, south of Easington, and walk first east to Skeffling Clough to start the stage proper. It's a beautiful day, blue skies and a light cool breeze. The tide is high and in this area the saltmarsh is narrow, just a small beach at the base of the sea wall. The area forms an embayment and Spurn Head and its lighthouse is in the horizon.
 There is a constant singing of Skylarks, and the more intermittent song of Whitethroats, Sedge Warblers and Reed Warblers as I pass through territories. Reed Bunting and Linnet are also quite common.

A large mixed flock of Dunlin and Grey Plovers in full breeding plumage passes by and settles towards Welwick Saltmarsh. There are still some Brent Geese about, and up to four Whimbrel along the walk.

Spurn Bight
This wide embayment between Sunk Island and the Spurn peninsula is called the Spurn Bight. It holds the most extensive mudflats in the Humber, about 3.5 km wide at low tide. If you have read previous posts you may not be surprised to know that proposals in 1860 were made to reclaim the Spurn Bight from Hawkins point to Spurn Head. These were never implemented due to prohibitive costs. However, more recent reclamation proposals were to use the bight to dump colliery waste to aid reclamation. These were eventually met with ecological considerations:
"The unique ecological character of Spurn Bight and the peninsula would be unlikely to survive total reclamation, although a partial scheme may preserve some important elements". 
Even as recently as 1979 the County Council couldn't 'be committed to the conservationist way'. Protection in the Humber estuary increased from a relatively small SSSI area around Spurn Head in the late 1960s to include most of the estuary coast by the late 1990s. When Natural England proposed in the late 1990s to designate 40,000 hectares of the Humber Estuary as a pSAC it wasn't a response to conservationists pressures but to criticism from the EU as the UK government had failed to implement SACs according to the Habitats Directive.

A disjointed landscape?
The Humber enjoys a high level or protection today, but this ends at the sea wall. Waders and other birds see no boundaries and many species regularly move between the estuary and the fields with the rhythms of the tide. Lapwing, Curlew, Golden Plover, Oystercatcher (above) and Shelduck (below) often feed or resting in the fields at high tide, so they are bound to be affected by the management regime.
Gulls and Crows do the same which explains the frequent crab remains on the sea wall.
The fields beyond the sea wall are farmed, often intensively. I watched a tractor spraying pesticide in one of the fields next to the seawall (below).
 A belt of more sensitively managed countryside around the Humber would be desirable, some type of buffer zone. A small area though, Kilnsea Wetlands, was been recently created by the Yorkshire Wildlife Trust and other partner organisations. What used to be 86 acres of intensively farmed land up to 2011 is now a nature reserve including shallow scrapes and ponds and wet grassland. It was created to compensate for habitat loss due to rising sea levels and coastal erosion, and it rapidly became a bird haven. Although I skirted the northern side of it today, I will visit it in my next stage.

What's in the mud?
Mudflats attract many waders and other birds at low tide. At high tide the birds move to sheltered belts of saltmarsh. But what are they feeding on when in the mudflats? I collected a few empty shells and carapaces from a small area in the estuary beach at Kilnsea, where I stopped for lunch (above). They included Baltic Tellins (Limecoma balthica), Peppery Furrow Shells (Scrobicularia plana), Cockles (Cerastoderma edule) and shore crabs (Carcinus maenas). Other very common mud organisms are ragworm (Nereis) and other worms, snails (Hydrobia ulvae and Retusa obtusa), mud shrimps (Corophium volutator) and many smaller ones like copepods and ostracods.

I spot a Wall Butterfly on the sea wall, in an area with a beach and a little saltmarsh. I see another two later.

I am very pleased to watch a pair of boxing hares, they chase all along a field on Kilnsea Wetlands and have a couple of skirmishes.
On the way back I have great views of four Whimbrels feeding on the exposed seaweed and muddy creeks near Sammy's point.
