Fish Remnant Patches: Urban Habitat Connectivity for Eight Species Groups in ACT

Eight species groups have modeled habitat connectivity layers for the urban ACT region. The data package includes connected habitat and remnant patch layers, each with attributes like Species Group, Patch ID, Habitat Type, and Patch Area. The ACT Government produced this data using expert-derived metrics and spatial connectivity models, last updated in April 2026.

Use Cases

• Identify core and corridor habitat patches for species groups based on the Habitat Type attribute.
• Calculate total connected habitat area for restoration planning using the Connected Habitat Area (Ha) field.
• Analyze fragmentation patterns by comparing Patch IDs across connected and remnant patch layers.
• Assess restoration potential by mapping remnant patches predicted to be inaccessible for species groups.

Strengths

• Data includes eight distinct species groups, allowing for multi-species analysis.
• Spatial resolution is 1:10,000, providing detailed geographic modeling.
• Modeling methods are based on expert elicitation for species-specific metrics like dispersal distance and barrier tolerance.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent for some fields; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the urban ACT region.
