Urban Habitat Connectivity Project: Amphibian Habitat and Fragmentation in ACT

A package of geospatial data containing potential habitat and fragmentation for eight amphibian species groups in the urban Australian Capital Territory. The data includes connected habitat layers showing core and corridor habitat and fragmentation layers showing remnant patches, developed using expert-elicited metrics and connectivity modelling. The data was published by the ACT Government and last updated in April 2026.

Use Cases

• Identify potential core and corridor habitats for amphibian species groups based on the Habitat Type attribute.
• Analyze fragmentation and connectivity between habitat patches using Patch ID and Connected Habitat Area.
• Plan restoration activities targeting fragmented remnant patches identified in the data.
• Calculate habitat area statistics for species groups using Patch Area (Ha) and Shape area attributes.

Strengths

• Data is modeled for eight distinct amphibian species groups.
• Includes two complementary layer types: Connected Habitat and Remnant Patches.
• Modeling metrics were derived from expert elicitation for species-specific requirements.
• Spatial resolution is 1:10,000 and uses the GDA2020 MGA zone 55 coordinate system.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation beyond the listed attributes is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the urban ACT region.
