Large Woody Debris in North American Taiga Lakes: 2194 Sampled Pieces

2194 pieces of Large Woody Debris (LWD) sampled along 3330 meters of shoreline in five lakes of the northern taiga in Quebec, Eastern Canada. The data were collected and analyzed by Fabio Gennaretti for the article 'Millennial stocks and fluxes of large woody debris in lakes of the North American taiga' published in the Journal of Ecology. Each row contains measurements for one LWD piece, including species, dimensions, dating information, and environmental context.

Use Cases

• Modeling carbon stocks and fluxes in lake ecosystems based on LWD volume and residence time data.
• Analyzing species distribution and decay patterns of submerged wood based on species and burial type.
• Reconstructing historical fire and disturbance events using charcoal presence and tree-ring dating.
• Studying shoreline geomorphology and sediment transport based on LWD orientation, distance from shore, and substratum type.

Strengths

• Contains 2194 individual LWD piece records, providing a substantial sample size for analysis.
• Includes detailed dating information such as tree-ring counts, radiocarbon dates (AMSDate), and residence times, enabling millennial-scale temporal analysis.
• Records multiple physical and environmental attributes per piece, including species, dimensions (diameter, length, volume), orientation, and burial state.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Last update date is unknown; freshness unverified.
• Data is geographically limited to five lakes in a specific region of Quebec, Canada.
