The dataset consists of diameter at breast height (DBH) measurements taken from trees and shrubs recorded in plots in 103 woodland sites surveyed across Great Britain in 1971 and again over the growing seasons of 2000, 2002 and 2003 (referred to as '2001 survey'), using exactly the same field methods. Data were collected under projects managed by The Nature Conservancy (in 1971) and the Centre for Ecology & Hydrology (in 2001).

Kirby, K.J., Smart, S.M., Black, H.I.J., Bunce, R.G.H., Corney, P.M., Smithers, R.J. (2005) Measuring Long Term Ecological Change in British woodlands (1971-2001): A re-survey and analysis of change based on the 103 sites in the ITE/NCC 'Bunce 1971' woodland survey. English Nature Research Reports 653.
Data were collected on paper from 103 woodlands by field surveyors employed by The Nature Conservancy, Merlewood Research Station, Cumbria (in 1971) and employed under a project managed by the Centre for Ecology & Hydrology (in 2000-2003). Extensive training was undertaken by surveyors. Collected data were double punched into spreadsheets as a form of quality control before being compiled into a database. Data collected are available as 4 separate datasets: flora data, soil data, tree diameter data and site details.
