2,890 priority species from UK country lists are tracked in this indicator measuring occupancy changes. The Joint Nature Conservation Committee published this data as part of a suite of 24 UK biodiversity indicators, with the latest data point from 2012. It is designed to show trends in the distribution of species of high conservation concern.
Use Cases
- Assessing conservation success based on trends in species distribution mentioned in the description.
- Comparing distribution trends with abundance data from indicator C4a as referenced.
- Identifying priority species with stable or increasing occupancy to evaluate recovery efforts.
- Analyzing geographic patterns in species decline across the four UK countries.
Strengths
- Covers 2,890 species identified as high conservation priority across the UK.
- Part of a formally published suite of 24 UK biodiversity indicators with a defined methodology.
- Explicitly linked to legal frameworks (Section 41 and 42 lists) for conservation priority.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2026-07-08 13:33:11.207747; freshness should be verified as the latest data point is from 2012.
