Herbicide Injury Data for Sub-Antarctic Weeds and Native Plants

Macquarie Island data details injury responses of Stellaria media and native plant species to herbicide treatments. The dataset comprises four files from three controlled experiments, measuring injury scores, seedling emergence, leaf counts, and dry weights. Research was conducted at the University of New England, with data published in 2018.

Use Cases

• Model injury_score for Stellaria media based on herbicide type and application_rate using data from the first experiment.
• Predict dry_weight and leaf_number outcomes from pre-emergence herbicide application at recommended and half-rates using the second experiment's data.
• Analyze herbicide selectivity by comparing injury data for three weeds and several native species across 0.25x, 0.5x, and 1x recommended rates from the third experiment.
• Correlate seedling_emergence metrics with herbicide treatment timing and species type to assess establishment success.
• Validate statistical models of plant injury using the provided graphs and analyses file from the three experiments.

Strengths

• Data from three distinct experiments testing 7 herbicides and a water control.
• Includes multiple response variables: injury scores (1-10 scale), seedling emergence, leaf number, and dry weight.
• Experiments test herbicide selectivity between invasive and native species under controlled sub-Antarctic conditions.

Limitations

• Sample size and row counts for each experiment are not specified.
• Data is from a single location (Macquarie Island) and controlled facility, limiting geographic generalizability.
• Temporal coverage is limited to the period of the thesis research, with no ongoing updates.
