Ptilotus Pyramidatus Population and Herbicide Impact Data 2016-2021

Six years of field and experimental data on the critically endangered plant Ptilotus pyramidatus, collected by Carl Gosper of the Department of Biodiversity, Conservation and Attractions. The data includes ramet counts from fixed quadrats under three weed management treatments and glasshouse tests on herbicide exposure. The dataset was last updated in May 2026.

Use Cases

• Model population trends of an endangered species based on six years of ramet count data.
• Compare the effectiveness of different weed management treatments (Reference, Weedy, Weeded) on plant survival.
• Assess the impact of the herbicide metsulfuron methyl on Ptilotus pyramidatus based on glasshouse experiment results.

Strengths

• Data spans six years (2016-2021), providing a longitudinal view of population trends.
• Includes experimental data from controlled glasshouse tests on herbicide impact.
• Compares three distinct field treatments (Reference, Weedy, Weeded) for ecological analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
