The purpose of this study was to take stock of the timber resources of woodlands and open grown trees in Great Britain and to assess the environmental status of trees in the urban and rural landscape by counties in England and Wales and by Forestry Commission regions (conservancies) in Scotland.

Main Topics:

Variables Area of woodland by forest type, age class, species, volume by ownership; estimate of the number of non-woodland trees by species, location, size class, health, and estimate of the volume of non- woodland trees.

Woodlands: three stage sampling system using O.S. 1:50 000 maps, aerial photographs and ground surveys for all woodlands not managed by Forestry Commission or under a dedicated approved grant scheme for which records were available and could be added to the survey results. Non-woodlands: two stage stratified random sampling system using aerial photographs and ground visits.
