Datasets

Current Activity

Collation of datasets on behalf of national recording schemes and socities is a key element of BRC’s work.  Datasets underpin the research the examples given throughout this website.  We support publishing datasets via the National Biodiversity Network Gateway, as listed below.

Key Outputs

BRC contributes to many distribution datasets shared via the NBN Gateway.  In addition, we develop datasets to support research applications - these include the Database of British Insects and their Foodplants (DBIF) and datasets on the ecological attributes of plants (PLANTATT) and bryophytes (BRYOATT).

Datasets on the NBN Gateway provided by BRC

Recording Invasive Species Counts (www.nonnativespecies.org/recording/) was launched in 2010 and includes on-line recording for 19 species including: Signal Crayfish, Pacifastacus leniusculus https://secure.fera.defra.gov.uk/nonnativespecies/factsheet/factsheet.cfm?speciesId=2498 The Signal Crayfish is designated as an ALERT species and also within RISC. The data is predominantly provided by members of the public but records are verified from photos by designated experts. The recording form includes the option to provide abundance and whether the individual is dead or alive (or unknown).
Atomariinae beetle data from the UK and Ireland. The data was collected by volunteers as part of the Atomariinae and Ptiliidae Recording Scheme. Recording cards were sent to BRC by the scheme organiser where they were converted to electronic format. The data is from the 1993 Atlas summarising information on the occurrence in Britain and Ireland of Atomariinae beetles in the genera Caenoscelis, Atomaria, Ootypus and Ephistemus.
The dataset comprises 81000 records of beetles from Britain and Ireland recorded to the end of 2016. The great majority of records are of water beetles, and site lists of these species are the most complete. Most of the rest are of rove beetles, marsh beetles and ground beetles collected from wetland margins. Over 99% of records were generated by the fieldwork of Bob Merritt. The remainder were collected by other parties, with the IDs being determined or confirmed by him.
This dataset is held at the BRC and was used for the 1991 publication: 'Provisional Atlas of the Larger Brachycera (Diptera) of Britain and Ireland'. The dataset covers robberflies, bee flies, soldierflies, horseflies and their allies. Data were collected by volunteer recorders and compiled by the Larger Brachycera Recording Scheme, which began in 1976.
This Trichoptera dataset originates from the National Trichoptera (Caddisfly) Recording Scheme. The survey data comes in four categories ranked in terms of contribution: volunteer recorders; statutory monitoring bodies, especially the Environment Agency; major national, and many local, entomological journals; museum collections. Recording is still continuing and annual up-dates are an aspiration. Many local check-lists are being prepared for electronic and paper publication. The data set contains records from a variety of well-circulated sources e.g the literature, that are considered incorrect. These are included, with an explanation, to flag-up that they have been assessed to assist researchers who encounter them elsewhere.
This Trichoptera dataset is part of the National Trichoptera (Caddisfly) Recording Scheme. The dataset comprises records entered via iRecord and verified online.
This Cerambycidae (longhorn beetle) dataset originates from the Cerambycidae Recording Scheme. All the survey data were collected by volunteers and compiled by the late Peter Twinn, formally the national scheme organiser. The recording cards were input to electronic format in BRC and an atlas was published in 1999 with text compiled by Paul Harding. Recording for the scheme is continuing under new leadership, with Martin Rejzek and Peter Hodge currently collating new records. No publications are expected at present.
This small dataset is held at BRC and covers six species of Ciid beetles. The Ciidae family is mainly associated with fungi growing on dead and dying trees. The dataset is derived mainly from record cards and the literature.
This dataset was updated with over 6000 new records in August 2006 and contains two data sources of Ladybird records:

1) Data held by BRC and originating from the voluntary Coccinellidae Recording Scheme run by John Muggleton. A draft atlas that included this data was produced in 1990 but never published.
2) New data from the Cambridge Ladybird Survey that were input from recording cards at BRC in 2006.
The Collembola dataset contains 359 species, records collected between 1808 - 2008, covering Great Britain and Ireland. It contains approximately 10,000 records.
The data originated from Alan Stubbs and John Kramer of the Cranefly Recording Scheme and includes their own records as well as those collated from various recorders. This is part of a larger dataset collected by volunteers from the Scheme. The data were either received on recording cards and input in BRC (2004-5) or were sent in electronic format from the scheme organisers. Non-cranefly species are also present in the dataset. An update was made to the dataset in summer 2006 to include another 41000 records from the Cranefly Recording Scheme.
The crayfish records in this dataset are fom three main sources. 1) Records were submitted to the Biological Records Centre as the result of a project funded by English Nature (formerly the Nature Conservancy Council) and the Environment Agency (formerly the National Rivers authority). The project was carried out at Nottingham University by Dr David Holdich, David Rogers and Ian Reeve. This dataset includes field records and records derived from published sources. They cover the period 1900 to 1996. The records have been verified by Holdich and his co-workers and subject to routine validation by BRC. 2) Records were collated from the Enviroment Agency by Peter Sibley in 2003. Records were extracted from EA files that had been collected during crayfish surveys by Agency staff, and from other sources. Records were also extracted from the EA macroinvertebrate database of samples collected by Agency staff in the field. This dataset covers the period 1900 to 2003. Records were verified by Agency staff and have been subject to routine validation by BRC. 3) A small additional dataset of Environment Agency records from the EA Northumbrian Region has been added. Uploaded 14th July 2004.
A collated information source on the distribution of all freshwater and estuarine fish species for Britain. The data are derived from a variety of sources and as such were collected by both professionals and volunteers.
The Derek Lott Coleoptera dataset comprises 61366 records collated by Derek Lott into the Stenus Research Coleoptera Database. Stenus Research is an entomological consultancy set up by Derek Lott in 2004. It inherited a large number of beetle records amassed by Derek Lott since 1982. To these were added records collected during projects carried out on behalf of a variety of government agencies and charities. This database contains all those records from Britain and Ireland that were either collected or identified by Derek.
This is a small historic dataset held at the BRC. It covers the Dixidae, or meniscus midges. Data were mainly collected by Nature Conservancy Council recorders and during the 1988 Dipterists' Field Week.
This dataset consists of the records collected and collated for the Odonata Recording Scheme (now the Dragonfly Recording Network), which led to the publication of the Atlas of the Dragonflies of Britain and Ireland (1996) by Merritt, Moore and Eversham. The scheme was run in association with the Biological Records Centre, where the dataset is now held. It contains not only the records made and submitted by the volunteer community, but also some from historical literature and museum sources. The records span the period 1807 (one from literature) to 1992, with 82% from 1975 to 1988.
The majority of records for this dataset are derived from the Orthoptera Recording Scheme. All the survey data were collected by volunteers and mainly derived from BRC recording cards input to electronic format in BRC. Some data were received in electronic format, having been verified by the Scheme organiser. Recording is still continuing although no publications are expected at present.
Multi-taxa structured surveillance of heathlands.
BRC records of Irish mammals. Confined to records of Otter (Lutra lutra) extracted from CHAPMAN, P.J. and CHAPMAN L.L. (1982) Otter Survey of Ireland, Vincent Wildlife Trust. These records were extracted in BRC from the above publication and are included here as a test dataset. The original records were professionally-collected as simple 10km square data on parts of the Irish grid. There is a notable geographic distribution of records by 50km square due to the collection methods that are described in the publication.
This dataset is held by BRC on behalf of the British Myriapod and Isopod Group and the Non-marine Isopoda Recording Scheme and contains non-marine species of Isopoda (e.g. woodlice and water-slaters). The data are derived from both the 1985 atlas, (details below) and also from more recent 'post-atlas' records. It is hoped that the exposure of this interim dataset on the NBN Gateway will stimulate interest in the production of a new, updated atlas. Such a publication would include a large number of new records, with a view to also including these new records in a future version of this NBN Gateway dataset.
Data are derived from the Neuroptera Recording Scheme and held at BRC. This dataset includes taxa from the orders: Neuroptera, Megaloptera, Raphidioptera and Mecoptera. The scheme was restarted in 1988 by Colin Plant and the data in this dataset were published in a provisional atlas in 1994 (details below).
Records for the UK Ladybird Survey, consisting of surveys for the harlequin ladybird, data from the London Natural History Society (collated by Paul Mabbott), and the UK Ladybird Survey. Data have been collated by the Biological Records Centre. Many people have provided data to both the Harlequin and the UK Ladybird Survey through the on-line surveys. The data from both on-line surveys (www.ladybird-survey.org and www.harlequin-survey.org) are collated within this dataset. Many county recorders, natural history societies and other wildlife groups have contributed to the survey, with the help of Paul Mabbott (London Natural History Society), Nigel Cuming and Jerry Bowdrey (Essex Field Club/Colchester Museum) and Michael Majerus. Many entomologists have provided survey data and this information is available in the Survey section.
This dataset consists largely of BRC mammal data used to create the 1993 'Atlas of mammals in Britain'. The data were collected by volunteers from the former Mammal Recording Scheme. Recording cards from the dataset were input to electronic format in BRC.
This dataset contains records from the 2006 atlas published by the British Myriapod and Isopod Study Group (BMIG) and the Biological Records Centre. It also includes records from the 1988 preliminary atlas of Millipedes. The British Myriapod Group was started at the Biological Records Centre in 1970 and recording under BMIG still continues today. The records in this dataset were collected and submitted to the scheme by voluntary recorders using RA13 and RA59 record cards.
UK mosquito distribution data derived from public collections and from an historical recording scheme.
NOTE: This data is superseded. It has been reviewed by County Moth Recorders and subsumed within the National Moth Recording Scheme dataset (https://data.nbn.org.uk/Datasets/GA001424). It is retained for querying specific records and is therefore not generally available. This was first GB-wide Lepidoptera mapping scheme, run by John Heath of BRC during the period 1967-1982. Butterfly data are excluded, as they are included in "Butterfly distributions for Great Britain and Ireland for the period 1690-1994 from Butterfly Conservation and BRC". There are very few records from Ireland, but the dataset held by BRC also includes the Channel Islands (not shown on the NBN).
This is a small, historic dataset held at the BRC which contains records of the Muscidae. This group includes houseflies and their allies. These data are attributed to the former Sepsidae and Muscidae Recording Scheme, now ceased operation.
The National Plant Monitoring Scheme (NPMS) is a habitat-based plant monitoring scheme designed by BSBI, CEH, Plantlife and JNCC. The aim is to collect data to provide an annual indication of changes in plant abundance and diversity. This dataset includes NPMS species occurrence data for England, Wales, Scotland; a companion but separate dataset is supplied for Northern Ireland.

This dataset includes both recent records published in the 2005 'Synopses of the British Fauna' and older data from the 1988 Provisional Atlas (further details below). The data originated from the Opiliones Recording Scheme (ORS) which began in 1973 and is jointly administered by the British Arachnological Society and the Biological Records Centre.
Distribution data on Orthoptera, Dermaptera, Dictyoptera and Phasmida submitted to iRecord and verified by the Orthoptera and Allied Insects Recording Scheme team.
This Pseudoscorpion dataset originates from the Pseudoscorpion Recording Scheme. All the survey data were collected by volunteers and compiled by Gerald Legg, the national scheme organiser. Prior to digitising the data an atlas was produced by Philip Jones under the auspices of Paul Harding using the card data in BRC. The recording cards were input to electronic format by Gerald Legg. Recording for the scheme is continuing. A revised Linnean Society Synopsis of the British Fauna: Pseudoscorpions in preparation as is a revised key.
Reptile and Amphibian records extracted from the BRC herptiles database. The dataset includes records from RHR Taylor, Frank Perrin and various other volunteer recorders. There is no official recording scheme for herptiles although some recording is ongoing within BRC. These data were input to electronic format in BRC from recording cards.

This is a historic dataset held at the BRC and used to create the 1986 Provisional Atlas (details below). It covers the sepsidae which are a group of scavenger flies. Data were collected by the Sepsidae and Muscidae Recording Scheme, now ceased operation.
This dataset includes records of Cantharidae (soldier beetles), Buprestidae (jewel beetles), Lampyridae (glow worms), Lycidae (net-winged beetles) and Drilidae. It originates from the Cantharoidea and Buprestoidea Recording Scheme that was started in 1984. Much of the data in this dataset was derived electronically from certain local records centres, having been collected by volunteers. Recording is still continuing although no new publications are expected at present.
This dataset includes data from the 'Provisional Atlas of the ticks (Ixodidea) of the British Isles' by K.P. Martyn, published in 1988 by the Biological Records Centre, Huntingdon, additional records submitted to the BRC and data collated through the Tick Recording Scheme. Twenty three species of ticks (Ixodidea, families Ixodidae and Argasidae) are mapped and the atlas also gives all host records. A fuller description of the dataset can be found in that publication. Regular updates have been made to the dataset to include new data from 1998-2007.
The UKBMS is a standarised monitoring scheme for monitoring butteflies in the UK. This dataset includes records from traditional fixed transect sites, often called 'Pollard Walks'; data from the Wider Countryside Butterfly Survey is excluded and available within a separate dataset. The UKBMS is run by Butterfly Conservation (BC), the Centre for Ecology and Hydrology (CEH), and the British Trust for Ornithology (BTO), in partnership with the Joint Nature Conservation Committee (JNCC), and supported and steered by Forestry Commission (FC), Natural England (NE), Natural Resources Wales (NRW), Northern Ireland Environment Agency (NIEA) and Scottish Natural Heritage (SNH).
Distribution data on 47 species of ladybird resident in the UK submitted to iRecord and verified by the UK Ladybird Survey team.
The records in this dataset come from two sources (loaded to the NBN Gateway as two separate surveys):

1) Aquatic Heteroptera Recording Scheme data collected mainly by volunteers and extracted from Thomas Huxley's database. (He was the previous Scheme Organiser).

2) Professionally-collected records from Lincolnshire provided by Richard Chadd of the Environment Agency.

The recording form includes the option to provide abundance and whether the individual is dead or alive (or unknown).
There are 1,455 SSSIs in Scotland of which some 150 or so are notified to protect their vascular plant interest. Site Condition Monitoring for vascular plant sites involves finding the (mainly) Nationally Scarce & Nationally Rare plant populations and making detailed records of them. The detailed records include population size, extent, regeneration, threat, habitat and environmental conditions together with a list of associated species. The first 6 year cycle began in 1998/9 and the survey work was variously undertaken by contractors, SNH Area staff and by BSBI volunteers and the BSBI Scottish Officer. John McKinnell, SNH, did much work to extract target records from some 92 of the completed SCM reports which were available to him.
The Dataset currently holds some 22,687 records. Virtually all have an 8 figure grid reference or better (94%) and have been made within the last ten years, and consequently the dataset is very valuable. The dataset has a number of limitations such as not all negative records were clearly recorded by surveyors and are included. The full list of limitations should be read before using the dataset for analysis or other purposes.
This dataset contains species records for the 11 familes of Diptera covered by the recording scheme, and that have been verified by the recording scheme. Records are from datasets made available via the iRecord verification process - these records may originate from direct addition of records to iRecord, or via other datasets that have been added to iRecord for verification purposes. The attributes of each record may vary depending on the dataset from which the record comes. Zero abundance records are not included.
This Stonefly dataset is part of the Plecoptera Recording Scheme. The dataset comprises records entered via iRecord and verified online.
Records for The Flora of Rum, by D.A. Pearman, C.D. Preston, G.P. Rothero and K.J. Walker (2008).
This database of some 356,000 records relates to c2500 taxa of flowering plants and ferns within 15 Scottish vice-counties. Most of these records have been collected by volunteer members of the Botanical Society of the British Isles (BSBI). The collated data have been validated by BSBI Vice-County recorders and the Biological Records Centre. The data was computerised over the period 2005-2009 by a project managed by the BSBI Scottish Officer Jim McIntosh and funded by Scottish Natural Heritage and The Esmee Fairbairn Foundation.
The dataset contains some 225,000 Vascular Plant Records relating to Perthshire, Angus and adjacent areas.
This database of 9.8 million records contains the distributions of 6669 taxa of flowering plants and ferns. Most of these records have been collected by volunteer members of the Botanical Society of the British Isles (BSBI) and include those gathered for the Atlas of the British Flora (Perring & Walters, 1962) and the New Atlas of the British and Irish flora (Preston, Pearman & Dines, 2002). The latter is a collation of many datasets (including those held by BSBI vice-county recorders), some included in this database in full and others as summary data; the major sources of data are outlined in the New Atlas text. The availability of data at resolutions higher than 10km square varies between sources. The collated data have been validated at the 10km square level by BSBI Vice-County recorders and the editors for those taxa mapped in the New Atlas, and were believed to provide a good representation of vascular plant distributions in Britain and Ireland at the time of publication. Records of infraspecific taxa and hybrids which were not mapped in the New Atlas have been scrutinised less closely. An update of around 900,000 records was made to the dataset in January 2007, to include the data from the BSBI Local Change survey (Braithwaite et al., 2006), data from the Flora of Oxfordshire (Killick et al., 1998) and the Isle of Wight Flora (Pope et al., 2003), records of hybrid plants and a variety of other records. Some corrections to the New Atlas dataset have also been made.
This database of 1.3 million records contains the distributions of 3922 species of flowering plants and ferns. Most of these records have been collected by volunteer members of the Botanical Society of the British Isles (BSBI) and include those compiled into the Vascular Plant Database maintained by BSBI and the Biological Records Centre (BRC) since the publication of the New Atlas of the British and Irish flora (Preston, Pearman & Dines, 2002). This includes data from a number of sources, including Professor Good’s archive of Dorset plant records, the BSBI Local Change survey (Braithwaite et al., 2006), data from the Flora of Oxfordshire (Killick et al., 1998) and the Isle of Wight Flora (Pope et al., 2003), Bedfordshire vascular plant records from JG and CM Dony and Chris Boon, records of hybrid plants and a variety of other records. The collated data have been validated at the 10km square level by BSBI Vice-County recorders
Data include a subset of iSpot records: www.ispotnature.org, those submitted via iRecord: www.brc.ac.uk/irecord and the MBA Indicia-based recording scheme: www.mba.ac.uk/recording. Records are verified by organisations and individuals with relevent taxonomic Expertise. This includes the Marine Biological Assocation and the Conchological Society.
