Technical document for an Official Statistic in Development for the 25 Year Environment Plan Outcome Indicator C6: Diverse seas: status of threatened and declining features 2025

Abstract

This report provides the technical and methodological background for the indicator “Diverse Seas: status of threatened and declining features”, which is being developed for the Outcome Indicator Framework (OIF), and is currently an Official Statistic in Development. The initial concept was published in 2024 (see JNCC Report 759, now archived and available through The National Archives website) and subsequently included as part of the OIF as Indicator C6.

The status of threatened and declining marine features in the UK are reported under various national legislation or international agreements. Initial C6 assessments have been undertaken using UK-relevant information published by OSPAR and Article 17 Habitats Directive assessments (this reporting requirement has since been translated into the Habitats Regulations). The C6 indicator provides a high-level summary of the status of marine and coastal features relevant to the UK listed under these two assessment sources (OSPAR and Article 17). To achieve this, the indicator results summarise the status assessments of listed features under different categories: habitats, marine mammals, marine birds, fish and reptiles.

Accompanying the report are two Excel workbooks containing the datasets referred to in the report:

  • Workbook 1: OSPAR Threatened and Declining (T&D) Species and Habitats Assessment Summary.
  • Workbook 2: Article 17 Marine and Coastal Species and Habitats Assessment Summary.
