Severn Estuary Waterbird High Tide Roost Sites and Habitat Characteristics

A spatial dataset identifies wintering waterbird high tide roost sites on the Severn Estuary SSSI/SPA. It characterizes habitat and waterbird composition, integrating data from BTO WeBS core counts, counter interviews, and site visits. The dataset was created by Natural England and was last updated on 2026-07-13.

Use Cases

• Assess potential impacts of coastal development plans based on identified roost site locations.
• Model habitat suitability for wintering waterbirds based on characterized habitat types.
• Inform conservation management strategies based on detailed waterbird composition data.
• Validate and enhance broader BTO WeBS survey data with detailed site-specific information.

Strengths

• Integrates multiple data sources: BTO WeBS counts, expert interviews, and field site visits.
• Provides detailed roost site characterization beyond standard survey data.
• Covers the Severn Estuary SSSI/SPA in four distinct geographical phases.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified despite the 2026 update date.
