Tree Diameter Measurements Across 103 British Woodlands 1971-2001

Diameter at breast height (DBH) measurements for trees and shrubs were recorded in plots at 103 woodland sites across Great Britain. Data were collected in 1971 and again over the 2000-2003 growing seasons using consistent field methods by The Nature Conservancy and the Centre for Ecology & Hydrology.

Use Cases

• Analyze DBH growth rates and changes over the 30-year period between the 1971 and 2001 surveys.
• Model tree and shrub diameter distributions across 103 different woodland site plots.
• Investigate environmental impacts on DBH by comparing measurements from the same sites surveyed decades apart.

Strengths

• Longitudinal data from repeated surveys at 103 sites over a 30-year period.
• Consistent field methods were used for all measurements across both survey periods.
• Geographic coverage spans woodland sites across Great Britain.

Limitations

• The specific number of rows (individual tree/shrub measurements) is unknown.
• Column names and data structure are not provided in the input.
• Data collection ended in 2003, offering no recent measurements.
