Southern Quebec Forest Inventory Sample Plots from 2017

Southern Quebec forest data from the fifth ecoforest inventory includes temporary sample plots covering 400 m2 each, established starting in 2017. Measurements include tree species, diameter, sunlight, floor relationships, defoliation, stem quality, age, height, undergrowth vegetation, and soil characteristics. The data supports forest compilation and opportunity calculations for public and private forests.

Use Cases

• Model forest growth and yield using tree species, diameter, age, and height measurements from sample plots.
• Analyze tree health and stress indicators by examining defoliation and stem quality data for deciduous trees and pines.
• Assess site quality and biodiversity by correlating soil characteristics with undergrowth vegetation survey results.
• Study forest structure and competition using sunlight and floor relationship observations between trees.

Strengths

• Data collection began in 2017, providing a multi-year baseline for analysis.
• Each circular sample plot covers a standardized 400 m2 area for consistent measurement.
• Includes detailed tree-level metrics like species, diameter, and health alongside plot-level soil and vegetation surveys.

Limitations

• Sample size and total row count are unknown, limiting assessment of statistical power.
• Geographic coverage is partial, restricted to the territory south of the 52nd parallel in Quebec.
• Data description is an automated translation, which may introduce ambiguities in variable definitions.
