Special Protection Areas (SPAs) bird assemblage details compiled for the EU Commission since December 2015. The data originates from Standard Data Forms submitted by the Joint Nature Conservation Committee and includes fields for site codes, species groups, and population size estimates. It is updated whenever new or amended information is submitted.
Use Cases
- Monitoring population sizes of waterfowl and seabird assemblages based on the OTHER_SPECIES_SIZE_MIN and OTHER_SPECIES_SIZE_MAX fields.
- Analyzing the distribution of protected bird assemblages across SPA sites based on SITE_CODE and COUNTRY_CODE.
- Tracking changes in species presence or absence over time based on the OTHER_SPECIES_NP (feature no longer present) indicator.
Strengths
- Data is updated with each new or amended batch submitted to the EU Commission.
- Explicitly notes that none of the assemblage data are sensitive (OTHER_SPECIES_SENSITIVE = 0).
- Provides quantitative population size estimates rather than broad categories.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data is only applicable from December 2015 onwards, with earlier data integrated elsewhere.
