Seabird 2000 Census: Breeding Population Counts for the British Isles

Seabird 2000 is a full census of breeding seabirds in Britain and Ireland conducted between 1999 and 2003. The dataset contains counts of 25 seabird species from coastal and inland colonies, mapped as points and polygons. Data was gathered by professional and volunteer ornithologists and is managed by the Joint Nature Conservation Committee.

Use Cases

• Modeling population trends for 25 seabird species based on census counts.
• Mapping seabird colony distributions based on geospatial point and polygon data.
• Establishing baseline population figures for conservation planning as mentioned in the survey objectives.
• Analyzing breeding site fidelity and colony size using sub-site counts along 1km coastal stretches.

Strengths

• Covers a complete census of all breeding seabirds in Britain and Ireland.
• Includes data for 25 regularly breeding seabird species.
• Data collection spanned a multi-year period from 1999 to 2003.
• Integrates surveys from both professional and volunteer ornithologists.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
