Southern Quebec Forest Inventory Plot Data 1980-1993

1980 to 1993 forest inventory data from southern Quebec includes measurements from circular 400 m2 sample plots. Plot data contains tree species, diameter, stage, defoliation, stem quality, age, height, and station survey information. The data was used to calculate forest opportunities for Quebec's public forests.

Use Cases

• Analyze tree species distribution and diameter measurements across sampled plots to model forest composition.
• Assess defoliation levels and stem quality data for deciduous trees and pines to study forest health.
• Model forest growth stages using tree stage classifications and height measurements from three trees per plot.
• Integrate plot location and sampling plan data for spatial analysis of forest inventory coverage.

Strengths

• Data collection spans a 13-year period from 1980 to 1993.
• Each circular sample plot covers a standardized area of 400 square meters.
• Geographic coverage includes almost all territory south of the 52nd parallel in Quebec.

Limitations

• Unknown sample size (row count) and specific feature count (columns) limits assessment of statistical power.
• Data is temporally stale, with collection ending over 30 years ago, limiting contemporary analysis.
• Original description is machine-translated, which may introduce ambiguities in variable definitions.
