Page updated on 9th August 2022
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.

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The idea behind this page is to highlight to recorders what key datasets are missing / far out of date and what level of detail can be seen or downloaded.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)
The newest invertebrate data from RECORD is from August 2016 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.
| Dataset | Resolution | Records upto | No. Records | Notes |
|---|---|---|---|---|
| Aculeate Hymenoptera (bee, wasps and ants) | 10 km | 24/08/2016 | 10,217 | No recorder or abundance info |
| Butterflies | 10 km | 24/08/2016 | 268,926 | No recorder or abundance info |
| Coccinellidae (ladybirds) | 10 km | 17/08/2016 | 8,445 | No recorder or abundance info |
| Odonata (dragonflies and damselflies) | 10 km | 17/08/2016 | 27,353 | No recorder or abundance info |
| Orthoptera (Grasshoppers and crickets) | 10 km | 17/08/2016 | 1,289 | No recorder or abundance info |
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.
| Dataset | Resolution | Records upto | No. Records | Notes |
|---|---|---|---|---|
| Butterflies | 10 km | 18/11/2014 | 7641 | Excludes any protected, UK BAP or any INNS (as defined by the Environment Agency). No recorder or abundance information. |
| Species of Conservation Interest in Greater Manchester | 10 km | 29/2/2016 | 15062 | Records of BAP and protected species in Greater Manchester not included in other GMEU data sets. Most records don't relate to invertebrates. |
| Bolton Museum Butterflies | 10 km | 20/9/2004 | 15275 | No recorder or abundance information |
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.
| Dataset | Resolution | Records upto | No. Records | Notes |
|---|---|---|---|---|
| LERN Records (includes all invertebrate groups) | 2 km | 31/12/2016 | 1417679 (incl. non-inverts) | Date only supplied at whole year resolution. No recorder or abundance info. |
Merseyside BioBank
BioBank publishes five datasets covering all invertebrate groups, including two datasets containing unverified records. The newest records are April 2020. 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). Recorder is now included in all datasets and abundance information in all but one. Overall, Biobank currently offers the most up to date and highest resolution data of all the regions LERCs.
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.
| Dataset | Resolution | Records upto | No. records | Notes |
|---|---|---|---|---|

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.
Many national 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. A few of latest invertebrate recording schemes to sign-up to regular NBN Atlas update via iRecord are:
- Auchenorrhyncha Recording Scheme (leafhoppers and allies)
- Hippoboscidae and Nycteribiidae Recording Scheme (flat-flies, keds and bat-flies)
- Kelp Fly Recording Scheme
- Oil Beetle Recording Scheme
- Rhinophoridae Recording Scheme (woodlouse-flies)
- Sciomyzidae Recording Scheme (snail-killing flies)
