Southwest Australia Plant Juvenile Period Under Future Climate

Southwest Australia contains modeled juvenile period data for serotinous obligate-seeder plant species under a future climate scenario. The dataset estimates years until 50% of a population flowers under the RCP 4.5 emissions scenario for a 30-year period centered on 2090. It was produced by Carl Gosper of the Department of Biodiversity, Conservation and Attractions to inform fire and conservation management.

Use Cases

• Model fire interval risks for conservation planning using juvenile period estimates.
• Analyze relationships between juvenile period and annual precipitation under the RCP 4.5 scenario.
• Spatially project juvenile period data across Mediterranean agro-climatic classes in southwest Australia.
• Compare standard and doubled (2×) juvenile period projections to assess population decline sensitivity.

Strengths

• Data is spatially projected across classic and drier Mediterranean agro-climatic classes within southwest Australia.
• Modeled for a specific future climate scenario (RCP 4.5) and time period (centered on 2090).
• Published under a Creative Commons Attribution (CC-BY) license for flexible reuse.
• Collated from several studies on serotinous obligate-seeder taxa, providing a synthesized resource.

Limitations

• Data is modeled based on environmental productivity measures, not direct field observations for all locations.
• Geographic scope is limited to southwest Australia, limiting applicability to other regions.
• Specific sample size, row count, and column structure are not provided in the input.
