Executive Summary We are requested by Karl Hankey from Raby Estates to provide a Preliminary Ecological Appraisal at Unthank, Harwood. An initial ecological assessment, bat and Barn owl surveys were undertaken at the property. 1.1 It is proposed to renovate and convert the existing buildings on site, no increase of building footprint is expected. 1.2 Desk top data searches indicate: a. The site is within the North Pennines AONB and its statutory sites. b. A rural upland setting – within Harwood Beck valley, within the inbye land. c. Habitats listed in the UK Priority Habitat Inventory are present around the site. d. Existing records indicate the presence of Barn owls within 5km of the site. e. We are awaiting bat data for the 2km of the survey area. 1.3 Field surveys were carried out on in 2021: a. Initial ecological assessment survey – March 17th 2021. b. Initial bird activity survey – March 30th 2021. c. Dusk bat and bird/ barn owl survey – April 11th 2021 1.4 Potential impact - priority habitats a. Upland Hay Meadow to the north - All building work to the north of the property to be retained within the existing fencing, no building rubble to spill onto the vegetation. b. Lowland fens – to the south east, adjacent to the road. No proposed alteration in the management of this parcel of land. c. Lowland fens – eastern paddock, potential change of use from fen to garden space. d. Former farmyard areas, at present hardstanding/bare ground to be used as storage and working areas for the proposed development. 1.5 Potential impact - protected species: a. Bats – preliminary assessment – the building is situated in an area with bat foraging and commuting habitat within 200m of the site these are not well connected to the surrounding habitat. Preliminary Ecological Appraisal F o r Unthank, Harwood F o r Raby Estates 23rd A p r i l 2 0 2 1 © AllAboutEcology - 1 - AllAboutEcology b. Bats – the buildings have potential roost features present – wall top eaves access and accessible crevices and cavities with limited potential to support occasional roosting bats. c. Bats – necessary roof work will be carried out following the enclosed Bat Method Statement following bat activity surveys. d. Barn owls – preliminary assessment – suitable foraging habitat is present around the site. e. Barn owls – have been recorded as present within the buildings within 2 years. f.

    Durham Rare Plant Register 2011 Covering VC66 and the Teesdale part of VC65 JOHN L. DURKIN MSc. MIEEM BSBI Recorder for County Durham 25 May Avenue. Winlaton Mill, Blaydon, NE21 6SF [email protected] Contents Introduction to the rare plants register Notes on plant distribution and protection The individual species accounts in alphabetical order Site Index First published 2010. This is the 2011, second edition. Improvements in the 2011 edition include- An additional 10% records, most of these more recent and more precise. One kilometre resolution maps for upland and coastal species. My thanks to Bob Ellis for advice on mapping. The ―County Scarce‖ species are now incorporated into the main text. Hieracium is now included. This edition is ―regionally aligned‖, that is, several species which are county rare in Northumberland, but were narrowly rejected for the Durham first edition, are now included. There is now a site index. Cover picture—Dark Red Helleborine at Bishop Middleham Quarry, its premier British site. Introduction Many counties are in the process of compiling a County Rare Plant Register, to assist in the study and conservation of their rare species. The process is made easier if the county has a published Flora and a strong Biological Records Centre, and Durham is fortunate to have Gordon Graham's Flora and the Durham Wildlife Trust‘s ―Recorder" system. We also have a Biodiversity project, based at Rainton Meadows, to carry out conservation projects to protect the rare species. The purpose of this document is to introduce the Rare Plant Register and to give an account of the information that it holds, and the species to be included.

  • Geometry of the Butterknowle Fault at Bishop Auckland (County Durham, UK), from Gravity Survey and Structural Inversion

Geometry of the Butterknowle Fault at Bishop Auckland (County Durham, UK), from gravity survey and structural inversion Rob Westaway 1,*, Sean M. Watson 1, Aaron Williams 1, Tom L. Harley 2, and Richard Middlemiss 3 1 James Watt School of Engineering, University of Glasgow, James Watt (South) Building, Glasgow G12 8QQ, UK. 2 WSP, 70 Chancery Lane, London WC2A 1AF, UK. 3 School of Physics, University of Glasgow, Kelvin Building, Glasgow G12 8QQ, UK. * Correspondence: [email protected]; Abstract: The Butterknowle Fault is a major normal fault of Dinantian age in northern England, bounding the Stainmore Basin and the Alston Block. This fault zone has been proposed as a source of deep geothermal energy; to facilitate the design of a geothermal project in the town of Bishop Auckland further investigation of its geometry was necessary and led to the present study. We show using three-dimensional modelling of a dense local gravity survey, combined with structural inversion, that this fault has a ramp-flat-ramp geometry, ~250 m of latest Carboniferous / Early Permian downthrow having occurred on a fault surface that is not a planar updip continuation of that which had accommodated the many kilometres of Dinantian extension. The gravity survey also reveals relatively low-density sediments in the hanging-wall of the Dinantian fault, interpreted as porous alluvial fan deposits, indicating that a favourable geothermal target indeed exists in the area.

  • The North Pennines
    LANDSCAPE CHARACTER THE NORTH PENNINES The North Pennines The North Pennines The North Pennines Countryside Character Area County Boundary Key characteristics • An upland landscape of high moorland ridges and plateaux divided by broad pastoral dales. • Alternating strata of Carboniferous limestones, sandstones and shales give the topography a stepped, horizontal grain. • Millstone Grits cap the higher fells and form distinctive flat-topped summits. Hard igneous dolerites of the Great Whin Sill form dramatic outcrops and waterfalls. • Broad ridges of heather moorland and acidic grassland and higher summits and plateaux of blanket bog are grazed by hardy upland sheep. • Pastures and hay meadows in the dales are bounded by dry stone walls, which give way to hedgerows in the lower dale. • Tree cover is sparse in the upper and middle dale. Hedgerow and field trees and tree-lined watercourses are common in the lower dale. • Woodland cover is low. Upland ash and oak-birch woods are found in river gorges and dale side gills, and larger conifer plantations in the moorland fringes. • The settled dales contain small villages and scattered farms. Buildings have a strong vernacular character and are built of local stone with roofs of stone flag or slate. • The landscape is scarred in places by mineral workings with many active and abandoned limestone and whinstone quarries and the relics of widespread lead workings. • An open landscape, broad in scale, with panoramic views from higher ground to distant ridges and summits. • The landscape of the moors is remote, natural and elemental with few man made features and a near wilderness quality in places.

  • Teesdale Local Plan Chapter 5 Population and Housing
    Teesdale Local Plan – Adopted June 2002 CHAPTER 5 POPULATION & HOUSING Teesdale Local Plan – Adopted June 2002 5) POPULATION & HOUSING 5.0 INTRODUCTION 5.0.1 The projected population of the district is inextricably linked to the District’s future housing requirements. The maintenance of a stable population is a realistic goal for the next ten years. Due to the ageing demographic structure of the district, in–migration would be required to achieve this goal. 5.1 POPULATION PROJECTIONS & HOUSING REQUIREMENTS 5.1.1 The housing requirements of the plan are calculated on the basis of Durham County Structure Plan Policy. Policy 7 of the Structure Plan states that Teesdale will require about 1,000 more dwellings between 1991 – 2006. As this Plan extends to 2010 the housing requirement calculation will need to make an estimate for the building requirement between 2006 and 2010. This is achieved by taking the Structure Plan figure, converting that to an annual building rate and thereby providing an estimate for the period 2006-2010. The housing requirement will also need to take into account those dwellings completed between 1991 – 1998. 5.1.2 According to the published 1991 census figures the Population of Teesdale is 24,068 of which 306 are in communal establishments, Population projections based on 1997 estimates show the population is expected to increase slightly to 24,193 by 2010, with the number of persons in communal establishments expected to remain constant, this would lead to 23,887 requiring housing. 5.1.3 As previously mentioned above, latest projections show a slight increase in population added to that the reduction in the average household size would result in the need for additional dwellings.

  • North Pennine Birdwalks Walk 12: Upper Teesdale the Birdwatchers Code of Conduct
    North Pennine Birdwalks Walk 12: Upper Teesdale The Birdwatchers Code of Conduct Birds are very vulnerable to disturbance, especially during the breeding season. It is all too easy to inadvertently harm a bird or its young while trying to watch them. For example, if an adult bird is prevented from returning to its nest, eggs or chicks may quickly chill and die. Straying from a footpath towards a nest site may also leave a scent trail that a predator is later able to follow. To ensure that you enjoy watching birds without harming them or their young, please always follow this code of conduct: • The welfare of the birds must come first. Disturbance to birds and their habitats should be kept to a minimum. • Keep to footpaths, especially during the bird breeding season (March – August). • Avoid disturbing birds or keeping them away from their nests for even short periods especially in wet or cold weather. • Do not try to find nests. All birds, nests, eggs and young are protected by law and it is illegal to harm them. • Keep dogs on a short lead. • Leave gates and property as you find them. • Take your litter home with you. Snipe 2 Birdwatching in the North Pennines GRADE - MEDIUM Walk 12 Upper Teesdale Forest in Teesdale Upper Teesdale is one of the best places to see waders in the breeding season and black grouse throughout the year. The wide expanse of the upper dale offers stunning views of the meadows and allotments and the imposing fells of Cronkley Scar and Widdybank. The River Tees is always impressive and there’s a chance of seeing birds such as dipper, goosander and oystercatcher.

This is the 2016, fourth edition of the “RPR”, dedicated to Keith Cunningham, who helped so much with the early databases and in many other ways. Improvements in this edition include- The new English Red List is incorporated into this edition. An additional 10% records, most of these more recent and more precise. Cover picture—Bird’s Eye Primrose at Widdybank Fell. Introduction Most counties are in the process of compiling a County Rare Plant Register, to assist in the study and conservation of their rare species. The process is made easier if the county has a published Flora and a strong Biological Records Centre, and Durham is fortunate to have Gordon Graham's Flora and the Durham Wildlife Trust’s “Recorder" system. We have also had a Biodiversity project, based at Rainton Meadows, which until 2013 carried out conservation projects to protect the rare species. It is hoped that the “RPR” will act as a stimulus for local botanists to make special efforts to improve the database by recording these species. The register will be used to increase our understanding of the status and distribution of the rare species, and to aid and promote their conservation. Species Covered Three groups of vascular plant species are included.

Heading south out of the village on the B6277, the river is crossed by a stone bridge. Just past the auction mart, a finger sign on the right shows the Pennine Way turning through a gate onto a hardcore track. This ends at a barn, from where a path continues along the edge of fields, crossing drystone walls by step stiles. At times the river comes into view as it meanders about the valley floor. A finger sign shows the route diverging from a drystone wall, heading diagonally across a couple of fields.
