ACT Climate Refugia for Plant Species Persistence Under Climate Change

ACT Climate refugia are core landscape areas most likely to support persistence of dominant trees, shrubs and grasses of the Capital Region under climate change. The data identifies refugia expected to support climate sensitive species characteristic of each vegetation community, based on distribution modelling using NARCLiM climate projections. The dataset was produced by the ACT Government's City and Environment Directorate and is available in multiple geospatial formats.

Use Cases

• Prioritize management actions like prescribed burning based on identified refugia areas.
• Plan climate-adaptive revegetation programs using modelled persistence areas.
• Analyze landscape-scale climate resilience for dominant plant species.
• Support conservation planning under the Nature Conservation Act using spatial refugia data.

Strengths

• Based on distribution modelling using NARCLiM climate projections.
• Focuses on dominant plant species modelled to lose >= 75% of their current distribution.
• Available in multiple geospatial formats including CSV, GPKG, and GEOJSON.

Limitations

• Areas smaller than 0.5 hectares have been removed for quicker map drawing.
• Column-level documentation is absent; field semantics must be inferred after download.
• For use as a broad scale product only, for example at 1:50,000 scale.
