Modern Pollen Counts From Western Québec Boreal Forests

Pollen assemblage data from modern surface sediment samples collected at ten study sites in boreal and northern temperate forests of western Québec, Canada. The dataset and accompanying R scripts were created by Jonathan Lesven to determine pollen count thresholds for robust assemblages, last updated in April 2026. It includes raw data used to generate figures and tables for a submitted manuscript.

Use Cases

• Analyze site-specific pollen assemblage composition using pollen count data from ten named locations (CSO3, Loup, Schön, etc.).
• Determine objective-specific pollen count thresholds for robust assemblages by modeling relationships between sample size and taxonomic representation.
• Reproduce figures and tables from the associated study using the provided R scripts and raw data files.
• Compare modern pollen spectra across a north-to-south transect of western Québec forest sites.

Strengths

• Data supports a submitted peer-reviewed manuscript, indicating academic review.
• Includes ten distinct study sites providing geographic breadth within western Québec.
• Full R scripts for reproducibility of all study figures and tables are provided.

Limitations

• Small dataset at 3.2 MB, limiting the scale of analysis.
• Unknown row and column counts for the underlying tabular data.
• Geographic scope is restricted to ten specific sites in western Québec.
