  • Some Elements of the Landscape History of the Five 'Low Villages'

    Some Elements of the Landscape History of the Five 'Low Villages'

    Some elements of the Landscape History of the five ‘Low Villages’, North Lincolnshire. Richard Clarke. Some elements of the landscape history of the five ‘Low Villages’, north Lincolnshire. The following twelve short articles were written for the Low Villages monthly magazine in 2014 and 2015. Part One was the first, and so on. In presenting all 12 as one file certain formatting problems were encountered, particularly with Parts two and three. Part One. Middlegate follows the configuration of the upper scarp slope of the chalk escarpment from the top of the ascent in S. Ferriby to Elsham Hill, from where a direct south-east route, independent of contours, crosses the ‘Barnetby Gap’ to Melton Ross. The angled ascent in S. Ferriby to the western end of the modern chalk Quarry is at a gradient of 1:33 and from thereon Middlegate winds south through the parishes of Horkstow, Saxby, Bonby and Worlaby following the undulations in the landscape at about ten meters below the highest point of the scarp slope. Therefore the route affords panoramic views west and north-west but not across the landscape of the dip slope to the east. Cameron 1 considered the prefix middle to derive from the Old English ‘middel’ and gate from the Old Norse ‘gata’ meaning a way, path or road. From the 6th and 7th centuries Old English (Anglo-Saxon) terms would have mixed with the Romano-British language, Old Norse (Viking) from the 9 th century. However Middlegate had existed as a route-way long before these terms could have been applied, it being thought to have been a Celtic highway, possibly even Neolithic and thus dating back five millennia.

Humberhead Levels Area profile: Supporting documents Introduction National Character Areas map As part of Natural England’s responsibilities as set out in the Natural Environment White Paper,1 Biodiversity 20202 and the European Landscape Convention,3 we are revising profiles for England’s 159 National Character Areas North (NCAs). These are areas that share similar landscape characteristics, and which East follow natural lines in the landscape rather than administrative boundaries, making them a good decision-making framework for the natural environment. Yorkshire & The North Humber NCA profiles are guidance documents which can help communities to inform West their decision-making about the places that they live in and care for. The information they contain will support the planning of conservation initiatives at a East landscape scale, inform the delivery of Nature Improvement Areas and encourage Midlands broader partnership working through Local Nature Partnerships. The profiles will West also help to inform choices about how land is managed and can change. Midlands East of Each profile includes a description of the natural and cultural features England that shape our landscapes, how the landscape has changed over time, the current key drivers for ongoing change, and a broad analysis of each London area’s characteristics and ecosystem services. Statements of Environmental South East Opportunity (SEOs) are suggested, which draw on this integrated information. South West The SEOs offer guidance on the critical issues, which could help to achieve sustainable growth and a more secure environmental future.

    DOUBLE NINE POCKLINGTON CANAL AMENITY SOCIETY Autumn 2011 No. 96 2 Editor’s Notes Well, another boating season is drawing to a close. Although not for everybody. (Remember Howard‟s article in our March Issue about winter cruising) New Horizons has had another record breaking year carrying around 2000 pas- sengers on more than 80 trips. Many thanks to all our volunteers who made this possible. For our „Spotlight On‟ subject ,this issue, we move away from featuring a PCAS Member and welcome the comments from Jon Horsfall, British Waterways North East Regional Manager. His views about the coming changes facing BW make very interesting reading. I am also delighted to have a contribution from Peter Hardy who compiled the very first Canal Guide for the Pocklington Canal. Many thanks to all our contributors without whom, we would not have a newsletter. Have you got something to say? A story about the Canal or indeed any waterway subject that may be of interest to our readers. Please contact me if you can help. I am happy also to publish letters (where appropriate) if you have any comments to make. It is always good to know what you think otherwise we are just working in the dark producing what we think you want to read. In the centre of this issue is a Membership Form. I apologise for repeating what is also said by others but PLEASE do fill this in even if you think you have nothing different to tell us.

    Draft Minutes of Brandesburton parish council meeting held on Monday, 11 September 2017 at 7.00pm in the Methodist Chapel Schoolroom. Present: Mr Olsen (chair), Mr Atkinson, Mrs Richardson, Mrs Mossford, Miss Coates, Mrs Wright, Mr Kittmer, Mr Richardson, Cllr Owen, Cllr Evison Apologies: Mrs Malcolmson, Mrs Whitfield, Mr Voase An open meeting was held for the first 30 minutes as residents had attended to discuss various matters. Proposed parking restrictions Main Street: Jackie Suthernwood had attended the meeting to speak regarding the proposed parking restrictions. Mrs Suthernwood was not happy with some of the restrictions proposed and would be putting in comments if and when it goes to consultation. Mrs Suthernwood commented that it is useful to have vehicles parking on Main Street as it acts as a traffic calming measure which would stop if they were no longer allowed to park. Heavy vehicles are causing houses to shake. Cllr Evison commented on the fact that although there are double yellow lines outside of the shops at present, delivery vehicles are allowed to park outside of the shops to deliver and also other vehicles can for a very limited period. The proposed restrictions would have no waiting and no loading restrictions at any time and delivery vehicles would then have to park at the side when making deliveries. If the restrictions are approved then there would be a period of embedding then after 1-month motorists would be ticketed if parking in no waiting areas. Allotments: An allotment holder attended to discuss various matters regarding the allotments. A letter had been sent to all of the allotment holders at the request of one of the allotment holders regarding the weeds growing in some of the plots.

    This Meanwood Valley Walk Download

    An introduction to the The Meanwood Valley has long been celebrated as a ‘green artery’ in Leeds, bringing rural countryside into the heart of the city. In this green corridor is a rich mosaic of habitats, including woodland, lowland heath, meadow, watercourses and ponds. Though much of the valley is readily accessible from local urban areas, it provides an excellent opportunity to experience and enjoy wildlife in often seemingly-remote surroundings. The valley is centred on two watercourses, the topmost being Adel Beck which rises in Bramhope, but which gives way to Meanwood Beck just south of the Outer Ring Road. The becks are home to fish, such as stone loach and bullhead, as well as the native white-clawed crayfish, which is sadly now threatened. Keep your eyes open when walking near the becks and you may be lucky to spot one of our resident kingfishers or otters. Where the becks flow between boulders and within the woodland, the cool, moist conditions provide the perfect habitat for ferns, liverworts and mosses. In contrast, the poor, free-drain - ing soils and open and exposed conditions at Adel Moor are ideal for heather and if you’re particularly lucky, you may spot the com - mon lizards which live here. Small ponds along the valley are also the breeding grounds of frogs, toads and newts, including the protected great crested newt. The woodlands that cover much of the green space in the valley provide wonderful scenes of carpets of ground flora in spring and rich colours in the autumn. Mammals such as roe deer, stoats and several species of bats make the woodland their home, together with a wide variety of bird species, from house sparrows and long-tailed tits to jays, red kites and all three native woodpecker – the great spotted, lesser spotted and green woodpecker.

From Sheffield it flows north-east to join the tidal Ouse at Goole. It has two tributaries, the Rother and Dearne. The Rother rises near Clay Cross in Derbyshire and joins the Don in Rotherham. The Dearne starts its life west of Denby Dale and flows through Barnsley and Mexborough, where it too meets the Don. The Don, Rother and Dearne catchment All three rivers pass through thriving, healthy rivers often Rother and the Dearne.
