Scots Pine Dothistroma Needle Blight Infection Assessments 2013-2015

Environmental Information Data Centre data from a progeny-provenance trial examining Dothistroma needle blight infection in native Scots pine populations. The dataset includes multiple infection assessments, tree height measurements, chlorophyll fluorescence, branching records, and defoliation assessments for each tree, plus measurements of infected needles. The experiment ran from April 2013 to September 2015 at Torrs Warren forest in Galloway.

Use Cases

• Model DNB infection severity progression over time using repeated infection assessments from 2013 to 2015.
• Analyze correlations between tree height measurements and defoliation assessment scores to identify resistant traits.
• Investigate lesion characteristics by examining data on length of lesions and number of lesions per infected needle.
• Assess tree health impacts by combining chlorophyll fluorescence measurements with defoliation assessment records.

Strengths

• Data includes multiple types of measurements per tree: infection severity, height, chlorophyll fluorescence, branching, and defoliation.
• Temporal coverage spans over two years with infection assessments performed roughly every six months from September 2013.
• Provides detailed needle-level pathology data including length of lesions and number of lesions per needle.

Limitations

• Sample size and number of rows are unknown, limiting assessment of statistical power.
• Geographic scope is limited to a single forest site (Torrs Warren, Galloway), reducing generalizability.
• Data collection ended in 2015, making the findings potentially stale for current pathogen strains or climate conditions.
