Scots Pine Dothistroma Needle Blight Surveys Across Three Scottish Sites, 2015-2025

Annual disease survey data for Scots pine trees in a long-term progeny-provenance common garden trial planted at three sites in Scotland. Trees were collected from 21 native Caledonian pinewood provenances across Scotland. Surveys were conducted annually from 2015 to 2025, excluding 2019 and 2020 at one site, and in 2016 and 2022 at two other sites.

Use Cases

• Assessing genetic variation in disease susceptibility based on tree provenance
• Modeling long-term disease progression and needle retention in Scots pine
• Comparing direct and indirect measures of Dothistroma needle blight impact
• Evaluating site-specific environmental effects on disease severity

Strengths

• Data spans up to 10 years, providing a longitudinal view of disease development
• Covers 21 distinct native provenances, allowing for genetic analysis
• Includes two complementary measures of susceptibility: direct lesion percentage and indirect needle retention

Limitations

• Survey frequency varies by site, with only two years of data for two of the three sites
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
