  4. Data resource: Bittern Annual Surveys in Britain 1990-2019

    This dataset contains results from annual national surveys that are undertaken to monitor the population of booming Bitterns (Botaurus stellaris) in Britain. The Bittern is a species of conservation concern. Breeding bitterns in Britain are typically restricted to reedbed (Phragmites australis) dominated habitat. Regularly-occupied sites and other sites with suitable breeding habitat within the bittern range are monitored for booming males annually.

  5. Data resource: Black grouse annual lek surveys by study groups in Speyside, Donside, Angus Glens and the Southern Uplands for the period 2018 to 2021

    This dataset is intended to provide an indication of black grouse lek data collected by black grouse study groups in Speyside, Donside, the Angus Glens and the Southern Uplands between 2018 and 2021. Black grouse is a species of conservation concern and as such has been monitored closely by these study groups. All summary lek data collected by study groups were collated by the GWCT with individual lek records held by contributing study group members.

  6. Data resource: Black grouse annual lek surveys in Argyll & Bute, 2002-2011

    These data were collected to monitor population levels in the Argyll & Bute area as part of the Black Grouse Recovery Project. Priority sites were identified for Black Grouse <I>Tetrao tetrix</I> conservation in the Argyll & Bute area. These priority sites were identified by surveying known (both historical and current) leks in Argyll & Bute between 2002 and 2011. <br /><br /> The recovery project was funded by a partnership of Scottish Natural Heritage, Forestry Commission Scotland, RSPB Scotland, Scottish Power and an award from the Esm饠Fairbairn Foundation. In 2008 additional survey work was organised and funded by RSPB. <br /><br /> Absence records are included, and denote areas that were surveyed where no black grouse were seen.

  7. Data resource: Black grouse lek survey in Lothian and Borders, 2008

    Black Grouse numbers in south-east Scotland fell by 69% between 1995/6 and 2005. In 2006-07, lek surveys were undertaken by the Southern Uplands Partnership, in an area occupying a rough triangle with Peebles, Selkirk and Moffat at its respective corners. This was considered to be the species local stronghold and the population here showed an apparent increase of 19% between the two years. In the spring of 2008, RSPB fieldworkers carried out a lek survey across 33 5km x 5km squares, chosen on the basis of historical records reported in The Breeding Birds of Southeast Scotland, 1988-94 (Murray <i>et al</i> 1998). These squares were outwith the core area surveyed by SUP in 2006/7, although one existing lek was checked here, and two new ones were discovered on its edge. In total, 18 leks were found comprising 1-7 Blackcock (mean = 2.7) and totalling 46 birds.

  8. Data resource: Black grouse lek survey in Moray and Nairn 2009

    The UK population of black grouse declined by 22% between the national surveys in 1995/6 and 2005. To establish core areas for recovery in the north of Scotland, black grouse strongholds have been surveyed for lekking males. These surveys attempted to fill in gaps left by previous, recent surveys.

  9. Data resource: Black grouse lek survey in Ross-shire

    The UK population of black grouse declined by 22% between the national surveys in 1995/6 and 2005. To establish core areas for recovery in the north of Scotland, black grouse strongholds have been surveyed for lekking males. These surveys attempted to fill in gaps left by previous, recent surveys.

  10. Data resource: Black grouse lek survey in Wester Ross and Skye 2009

    The UK population of black grouse declined by 22% between the national surveys in 1995/6 and 2005. To establish core areas for recovery in the north of Scotland, black grouse strongholds have been surveyed for lekking males. These surveys attempted to fill in gaps left by previous, recent surveys.

  11. Data resource: Black grouse lek surveys in Sutherland

    To establish core areas for recovery in the north of Scotland, black grouse strongholds have been surveyed for lekking males. This dataset contains lekking males recorded in surveys undertaken in 2002, 2008 and 2009.

  12. Data resource: Black grouse lek surveys in the Scottish Borders, 2010-2011

    Black Grouse numbers in south east Scotland fell by 69% between 1995/6 and 2005. This survey was designed to provide lek distribution, and a count of lekking birds, expanding on the areas covered by smaller surveys in 2006, 2007 and 2008. This dataset contains all the positive records, some of which are multiple counts of the same birds. Hence, the sum of birds in this dataset does not match with the reported total of 230 leking males. Some data are omitted due to a confidentiality agreement with the land owner. The survey was conducted by the Southern Upland Partnership, which is supported by SNH, the European Agricultural Fund for Rural Development, Leader, and the RSPB.

  13. Data resource: Black grouse leks in the Forest of Clunie, 2002-2011

    The Forest of Clunie is made up of five moorland areas in north-east Perthshire, and is designated SPA and SSSI for its variety of upland breeding birds. It is nationally important for black grouse. SNH operate a moorland habitat management grant scheme in the area. All farms and estates within the SSSI are included, in addition to those with suitable habitat, outwith but adjacent to the SSSI. This dataset contains records of lekking males from within the management area. There is some overlap between records in this dataset, and records collected by the Perthshire Black Grouse Study Group (GA000760). The Forest of Clunie surveys were funded by Scottish Natural Heritage (SNH).

  14. Data resource: Black grouse national surveys

    The male black grouse <I>Tetrao tetrix</I> population in Britain was surveyed in 1995/96 and 2005, in order to estimate population size. <br /><br />The surveys were based on counts of males displaying in the spring. In Wales and Staffordshire, the entire known population was surveyed in 1995. In northern England and Scotland in 1995/96 and 2005, and in Wales in 2005, a stratified random sample of 5 km squares from the breeding range was surveyed. As such the dataset covers around 10% of the UK population overall and does NOT contain all black grouse leks in Britain in the survey years; its aim was to produce a reliable population estimate. <br /><br />The 5 km squares where no black grouse were found will be included in the dataset when zero record display becomes available on the NBN. <br /><br />The 1995/96 survey estimated a population of 6510 males, the 2005 survey estimated population size to be 5078 males, a non-significant 22% decrease.<br /><br /> The surveys were organised by the Statutory Conservation Agencies and RSPB Breeding Bird Surveys (SCARABBS) scheme. The 1995/96 survey was funded by the RSPB, Scottish Natural Heritage, English Nature (now Natural England), the Joint Nature Conservation Committee and the Game Conservancy Trust (now the Game and Wildlife Conservation Trust). The Perthshire Black Grouse Study Group carried out a substantial part of the fieldwork. The 2005 survey was funded by the RSPB, the Countryside Council for Wales, Forestry Commission Scotland, the Game Conservancy Trust (now the Game and Wildlife Conservation Trust) and the Defra Rural Development Service (now part of Natural England), and organised with substantial help from the Central Scotland Black Grouse & Capercaillie Study Group, the Perthshire Black Grouse Study Group and the Strathspey Black Grouse Study Group.

  15. Data resource: Black-tailed godwit (Limosa limosa limosa) population size at breeding sites in East Anglia, UK, 2017-2021

    Numbers of breeding pairs of black-tailed godwit (Limosa limosa limosa) recorded at breeding sites in East Anglia, UK, 2017-2021.

  16. Data resource: Black-throated Diver annual records in North Scotland, 1834-2019

    This dataset pulls together all available information from a wide range of sources to give a single line summary for Black-throated Diver breeding territories in North Scotland Region in each year where information is available. Principal sources of information are the RSPB's diver raft project and from other landowners; as well as records submitted for inclusion in the Highland Bird Report and public sightings. Other data was sourced from NTS, NS, SWT, RBBP and Forestry and Land Scotland amongst others. Much of the pre-1985 data comes from a historical dataset compiled by Greg Mudge in the early 1990s that sourced many museum collections etc. In the case of multi-territory lochs, some historical data just refers to the whole loch and does not indicate which territory the record is from. In such cases, a separate entry is made like 'loch name' consolidated. The inclusion of a site in this dataset does not neccesarily mean that it is a known breeding site. Some sites are included for future reference as a pair has been noted present in the egg laying period (27 April to 15 June). The dataset has been split into two different surveys, one contains data from egg collection (Records from egg collection), and the other contains the records from annual surveys (Records from annual surveys).

  17. Data resource: Black-throated diver national surveys in Scotland

    Black-throated divers are birds of conservation concern due to the small UK population size, and large declines in the European population in the 20th century. This dataset contains records of black-throated divers from the national surveys conducted in 1985, 1994 and 2006. The 2006 survey details unique site visits, and individual birds may be reported in more than one record, recorded on different visits to the same site. The survey indicated a significant increase of 16% between 1994 and 2006. The 1985 and 1994 surveys in this dataset are breeding summaries of summering territories. The 1985 survey is incomplete, and is missing seven summering territories reported by Campbell and Talbot (British Birds, 1987). In addition to the data collected for the national surveys, this dataset also contains data collected on additional visits in the survey years. These data are either from sites that were not included in the surveys, or from sites visited outside the survey period. These data are clearly flagged in the dataset. The surveys were carried out by the Royal Society for the Protection of Birds (RSPB) and Scottish Natural Heritage (SNH) under the Statutory Conservation Agencies and RSPB Breeding Birds Scheme (SCARABBS).
