Purpose

This layer was created for inclusion in the Victorian component of the Australian Oil Spill Response Atlas. 

Supplemental Information

Relationship to other Datasets: The 1:25,000 digital coastline of Victoria and 1:25,000 hydrology were predominantly used as base layers to identify site locations. Future Design Issues: Other points may be added if regions not previously covered are surveyed in the future. Related Documents: None

Missing Data

The layer is complete for major bird roosts in coastal Victoria, but more sites are likely to exist in some regions where detailed surveys have not been undertaken. 

Attribute Quality

Attributes have been verified by the Fish and Habitat Ecology Section, Fisheries Research Branch, DPI Queenscliff, and are complete. 

Positional Accuracy

The horizontal and vertical accuracy of the site locations have not been verified in the field. These points represents the approximate centre of the primary shorebird roosting sites, but bird species may also move into adjacent or surrounding areas depending on daily weather conditions, winds, variations in coastal environments etc. 

Lineage

Description

This layer was created by combining two earlier OSRA shorebird datasets, one containing coastal roosting sites, the other containing roosting sites in Port Phillip Bay. The new layer was then updated with new sites. Shorebird roosts were either digitised from maps found in the relevant information sources, interpretation of aerial photography or by utilising the digital 1:25,000 coastline and hydrographic layers as base layers. 

Statement

Dataset Source: Information was mainly derived from databases maintained by the Arthur Rylah Institute, Birds Australia, Bird Observers Club and Australian Wader Study Group. Other information has been derived from published reports and also personal observations of bird observers, coastal rangers and other relevant coastal management personnel. Dataset Originality: Primary & Derived
