  2. Data resource: Bringing Reedbeds to Life Amphibian Survey of two key reedbed sites in England in 2010

    Bringing Reedbeds to Life is an innovative programme of scientific research and habitat monitoring, coupled with practical habitat management advice and training. It represents one of the largest co-ordinated programmes of such work on reedbed wetlands for over a decade. The project aims to generate a better understanding of the requirements of a wider range of reedbed wildlife. This enhanced understanding will be used to inform advice, training, management and future conservation strategies across England's reedbeds. <br /><br /> Spawn searches for common frogs, bottle trapping for newts and auditory and visual searches for marsh frogs were carried out between February and May 2010. Surveys were conducted at RSPB Ham Wall NNR (Somerset) and NE Stodmarsh NNR (Kent). The species encountered in systematic surveys were common frogs (<i>Rana temporaria</i>); marsh frogs (<i>Pelophylax ridibundus</i>) and smooth newts (<i>Lissotriton vulgaris</i>). Adult common toads (<i>Bufo bufo</i>) were observed in reedbed habitat at Ham Wall but were not encountered on systematic surveys. <br /><br /> The project was led by RSPB with 50% funding from Natural England via the Countdown 2010 Biodiversity Action Fund and working in partnership with other partners such as Wildlife Trusts, The National Trust and independent ecological contractors.

  3. Data resource: Bringing Reedbeds to Life Invertebrate Survey of three key reedbed sites in England in 2009, 2010

    Bringing Reedbeds to Life is an innovative programme of scientific research and habitat monitoring, coupled with practical habitat management advice and training. It represents one of the largest co-ordinated programmes of such work on reedbed wetlands for over a decade. The project aims to generate a better understanding of the requirements of a wider range of reedbed wildlife. This enhanced understanding will be used to inform advice, training, management and future conservation strategies across England's reedbeds. <br /><br /> Water traps for aerial invertebrates, pitfall traps for ground-dwelling invertebrates, light traps for Lepidoptera and aquatic netting for aquatic invertebrates were carried out at 3 reedbed sites: Norfolk Wildlife Trust NNR Hickling Broad (Norfolk), Natural England NNR Stodmarsh (Kent), and RSPB NNR Ham Wall (Somerset). Water trap, pitfall trap and aquatic netting surveys were undertaken between June and August 2009. Light trapping for moths was done between June and August 2010. <br /><br /> The project was led by RSPB with 50% funding from Natural England via the Countdown 2010 Biodiversity Action Fund and working in partnership with other partners such as Wildlife Trusts, The National Trust, Buglife, independent ecological contractors, Butterfly Conservation.

  4. Data resource: Bringing Reedbeds to Life Water Vole and Mink Survey of five key reedbed sites in England in 2009, 2010

    Bringing Reedbeds to Life is an innovative programme of scientific research and habitat monitoring, coupled with practical habitat management advice and training. It represents one of the largest co-ordinated programmes of such work on reedbed wetlands for over a decade. The project aims to generate a better understanding of the requirements of a wider range of reedbed wildlife. This enhanced understanding will be used to inform advice, training, management and future conservation strategies across England's reedbeds. <br /><br /> Water voles were surveyed using two methods: water vole rafts within reedbeds and mink rafts in ditches. This is the first such systematic survey of water vole use of the internal parts of reedbeds as far as we are aware. In addition, mink records from mink rafts in ditches were analysed. Water vole raft surveys were carried out at 3 key reedbed sites: RSPB Ham Wall NNR (Somerset), NE Stodmarsh NNR (Kent) and NWT Hickling Broad NNR (Norfolk). Mink raft surveys were carried out at five sites, the additional two being Lincolnshire Wildlife Trust Far Ings NNR and National Trust Wicken Fen (Cambridgeshire). <br /><br /> The main finding of the surveys was that water vole was present at the five reedbed sites despite the presence of mink also. Therefore reedbeds provide a habitat where the two species can coexist.

  5. Data resource: Bryophyte data for Great Britain and Ireland from the British Bryological Society held by BRC: data compiled post-Atlas

    Bryophyte records submitted to the Biological Records Centre for England, Ireland, Scotland, Wales, the Isle of Man and the Channel Islands. The dataset comprises records collected for the Bryophyte Recording Scheme, as well as those extracted from literature and museum sources. Details of all the surveys in this dataset can be obtained by clicking the 'Surveys' tab. This 'post-Atlas' dataset contains records received by the BBS after the production of the 2014 Atlas (Blockeel et al. 2014); it also contains any records that have been redetermined since inclusion in the 2014 Atlas (with the original records removed from the Atlas dataset GA000144). This new dataset currently contains records covering 139 vice-counties, with over five hundred records for each of the following (in descending order of abundance): Glamorgan, Cheshire, South Northumberland, East Sussex, West Sussex, Derbyshire, Merionethshire, Carmarthenshire, North Somerset, Renfrewshire, Shropshire (Salop), Cambridgeshire, East Norfolk, West Norfolk, East Suffolk, Anglesey, West Suffolk, Mid-west Yorkshire, Huntingdonshire, Buckinghamshire, Surrey, North-east Galway, Mid Perthshire, Breconshire, Outer Hebrides, South Hampshire, Caernarvonshire, South Devon, Argyll Main, East Cornwall, Nottinghamshire, South-west Yorkshire, Dumfriesshire, Northamptonshire, Offaly, West Inverness-shire, West Cornwall (with Scilly), South Wiltshire, Westmorland with North Lancashire, North Wiltshire, North Devon, Louth, Durham, South Lancashire, East Inverness-shire (with Nairn), North-west Yorkshire, Peeblesshire, West Galway, North Northumberland (Cheviot), and Cumberland.

  6. Data resource: Bryophyte data for Great Britain from the British Bryological Society held by BRC: Atlas 2014

    Bryophyte records submitted to the Biological Records Centre for England, Ireland, Scotland, Wales, the Isle of Man and the Channel Islands. The dataset comprises records collected for the Bryophyte Recording Scheme, as well as those extracted from literature and museum sources. Details of all the surveys in this dataset can be obtained by clicking the 'Surveys' tab. This 'Atlas' dataset contains all of the records presented in Blockeel et al.

  7. Data resource: Bryophyte Survey of the Poole Basin Mires - NBN South West Pilot Project Case Studies

    The mires of the Dorset Heaths provide a refuge in southern England for many plants which have declined in other parts of the country due to drainage, peat-cutting and afforestation. The group of plants which dominate these peatlands are the Sphagna or Bog-mosses. Dorset retains population of 13 species and 6 subspecies of the 26 species and 9 subspecies found in Britain. The aim of this survey was to survey all sites in the Poole Basin with mire habitats. For each mire all Sphagnum species and associated mosses and liverworts were recorded.

These records are from the data holdings of Dorset Environmental Records Centre which covers both terrestrial and marine taxa, the majority dating from 1976 onwards but also including historical records. The database includes records from site and species surveys by staff and local naturalists, extractions of records from literature, records from other organisations which hold records for Dorset, and records sent in by the general public. The data quality is therefore variable but all records have been through a basic validation process by local experts before entry. This dataset has been submitted to the NBN Gateway as part of the South West Pilot Project Case Studies work.

  10. Data resource: BTO First Atlas of Breeding Birds in Britain and Ireland: 1968-1972.

    The dataset was used to produce the first BTO/IWC Breeding Atlas 1968-72 (Sharrock, J.T.R. (1976) The atlas of breeding birds in Britain and Ireland. T. & A.D. Poyser). <br /><br /> Volunteer (mostly) observers compiled as complete a list as possible of breeding bird species in each 10-km square and noted whether the species was Possibly, Probably or Confirmed as breeding -- a series of standard categories (and codes) were used to specify these, categories which have since, with mostly minor modifications, become a worldwide standard. To make the set directly comparable to the Second Atlas these were converted into S -- Seen (for Possibly Breeding) or B -- Breeding (for Probably and Confirmed Breeding).
