The State of Access to NW Invertebrate Data via NBN Atlas

Page updated on 11th Sept 2020

The National Biodiversity Network (NBN) Atlas provides a platform for the UK biological data to be shared. It is run by NBN Trust, a charity with the aim of improving the availability of high resolution and high quality data to provide the evidence base for all environmental decision-making in the UK. Learn more

For invertebrate recorders, NBN Atlas can provide important context about a species record: is it rare? Is it new to the area / county? Does this record represent a distributional expansion? However, it’s sometimes unclear how comprehensive or up to date the picture of records you’re seeing is.

The idea behind this page is to highlight to recorders what key datasets are missing / far out of date and what level of detail can be seen or downloaded. This can help indicate what further research may be needed (e.g. contacting a LERC or Scheme for data). County Recorders, local atlases, checklists and museum collections are other important sources to check. Many new and historical NW checklists are downloadable from the resources pages, including signposting of online local atlases. Go to resources.

Local Environmental Records Centre datasets

RECORD (Cheshire)

No invertebrate datasets have been submitted to NBN Atlas for over 4 years and current datasets only cover a very limited number of families / orders. For example, there are no records for two major orders; Diptera (True Flies) and Hemiptera (True Bugs), and Coleoptera (Beetles) is only represented by a single family; Coccinellidae (Ladybirds). The current datasets (below) are only available at low resolution (10 km) with no recorder or abundance information.

Higher resolution (2 km for non-protected species) access covering all invertebrate groups is provided via the RECORD website Data Search Facility but recorder names are not included and data cannot be downloaded (although is it possible to copy and paste each results page). Full resolution data is usually made available to the (voluntary) recorder community at no cost by contacting info@record-lrc.co.uk. Go to Data Search Facility.

Greater Manchester Ecology Unit (GMEU)

None of the three datasets containing invertebrate records have data newer than February 2016 and most records are for butterflies only at low (10 km) resolution without recorder or abundance information (see table below). There may be a small number of protected invertebrates species records from other taxonomic groups contained in the ‘Species of Conservation Interest’ dataset, also at low resolution with no details. 

Access to full resolution data for volunteer recorders and groups can usually be given free of charge by request to info@gmwildlife.org.uk. More information can be found on the GMEU website

Lancashire Environmental Record Network (LERN)

LERN publishes the vast majority of records in a single dataset on NBN Atlas at 2 km resolution, covering all invertebrate groups (see table below). The most records are 31/12/2016. No recorder, site or abundance information is included and dates are in whole year format only.

Access to full resolution data for volunteer recorders and groups can usually be given free of charge. See LERN’s Data Sharing and Usage Policy.

Merseyside BioBank

BioBank publishes five datasets covering all invertebrate groups, including two datasets containing unverified records. The newest records are Feb 2017. All datasets are downloadable at 2 km resolution with the exception of ‘North Merseyside Local Species Data’, which is available at full resolution (see table below). No recorder, site or abundance information is included in any dataset.

Access to full resolution data for volunteer recorders and groups can usually be given free of charge but see BioBank’s Partner Support webpage and contact info@merseysidebiobank.org.uk for more information.

National Recording Schemes

Access to National Recording Scheme data via NBN Atlas varies between schemes from completely up to date datasets with hundreds of thousands of detailed records at full resolution all the way through to no data published. There can be a variety of reasons for such discrepancies in data availability via NBN Atlas such as capacity, resources (most schemes are run by volunteers), and data sharing policies.

22 schemes (+ other surveys) currently have an arrangement between the Biological Records Centre (BRC) and NBN Atlas whereby iRecord datasets are updated every 2 months at full resolution (see iRecord NBN Sharing page for the most up to list). This represents the closest to ‘live’ invertebrate data currently available via NBN Atlas. Some schemes such as those run by the British Arachnological Society and BWARS whom don’t currently publish datasets on NBN Atlas host informative websites with distribution maps, status and ecological information for UK species.
