Carnaby's Black Cockatoo Unconfirmed Roost Buffers

2026 data from David Mitchell at the Department of Biodiversity, Conservation and Attractions details unconfirmed roost sites for Carnaby's Black Cockatoo. Each reported roost location is buffered by a 6-kilometer radius to model potential feeding areas. This spatial layer is designed for integration with related feeding, breeding, and confirmed roosting data.

Use Cases

• Model potential feeding area extents by analyzing the 6-kilometer buffer geometry around each unconfirmed roost site.
• Integrate this buffered roost layer with confirmed roost and breeding data layers for comprehensive habitat suitability analysis.
• Assess reporting accuracy and roost movement by comparing unconfirmed buffered sites with field survey validation data.

Strengths

• Includes a defined 6-kilometer buffer applied to all sites to account for roost movement and recording accuracy.
• Published under a Creative Commons Attribution (CC-BY) license for flexible reuse.
• Maintained by the authoritative Department of Biodiversity, Conservation and Attractions.

Limitations

• Roost sites are labeled 'unconfirmed', indicating they lack validation from official survey counts, which may introduce location inaccuracy.
• The dataset's utility is dependent on external feeding, breeding, and confirmed roosting layers mentioned in the associated report.
