UK Biodiversity Indicators 2023

Updated 14 November 2023

The 2023 update of the UK Biodiversity Indicators, published on 14 November 2023, comprises updates to 18 indicators.

The UK is fortunate in having lots of information about its biodiversity, collected across a broad spread of species and habitats both by professionals and by expert volunteers. This information provides an essential source of evidence for reporting biodiversity change and the impact of policies and actions to conserve biodiversity.

Full information for each individual indicator is available online – this includes charts, assessments and access to background information and resources, including data and technical background documents.

Biodiversity policy is a devolved responsibility in the UK; England, Scotland, Wales and Northern Ireland have each developed, or are developing, their own biodiversity or environment strategies. Indicators are being developed to track progress with the respective commitments in each country. The UK indicators have a specific purpose for international reporting and were selected following consultation and agreement between the administrations. The indicators provide a flexible framework and a common set of methodologies which in some cases can also be used for country reporting. 

The UK Biodiversity Indicators are dependent on a wide variety of data, provided by government, research bodies, and the voluntary sector – in total nearly 100 organisations are involved. The presentation and assessment of the indicators has been verified by the data providers, and the production and editing of the indicators has been overseen by government statisticians.

There are two processes for sign-off of the UK biodiversity indicators:

  1. Options for new UK biodiversity indicators may be developed through a number of routes, for example, under contract to Defra or JNCC, or by JNCC working with the statutory agencies and public bodies and/or relevant NGOs. The UK Biodiversity Indicators Steering Group (BISG) is responsible for agreeing that any such option is appropriate to the subject of a biodiversity indicator, and that the presentation is fit-for-purpose (a change to the subject area has to be signed off by the four countries in the UK). Once an indicator has been agreed through BISG, it is the responsibility of the Indicator Project Group (Defra and JNCC) to implement it. The Project Group will make decisions as necessary about detailed presentation or technical issues without referring back to the Steering Group. However, if as a result of changes in the context in which the indicators are presented a new measure or indicator seems to be warranted, the Project Group will bring that back to the Steering Group for further discussion and/or a final decision.

  2. Once agreed through the Steering Group, both new and existing indicators and measures will be incorporated into the annual update process for the biodiversity indicators (noting that some measures can only be updated at less regular intervals). This process is managed to comply with the provisions of the Statistics and Registration Service Act 2007; essentially this means ensuring that only those who need to be involved see the details of the data before the indicators are published. The work proceeds through a series of steps:

    1. for each of the indicators, one of the Project Group members takes a lead role;
    2. once data have been sourced, the lead prepares the graphical presentation and assessment, and updates the rest of the fiche as necessary;
    3. their work is then checked by another member of the project group;
    4. where appropriate, the revised fiche is sent back to the data providers for quality assurance, to ensure that the data have been correctly presented and objectively interpreted, and that appropriate examples have been incorporated within the fiche text;
    5. further edits are then made by JNCC and Defra as necessary in order to incorporate feedback from the quality assurance process; and
    6. a finalised fiche is published on the JNCC website, with links from GOV.UK.
