National Forest Inventory - preliminary broadleaved and ash data GB 2011

A summary NFI report of the 2011 preliminary estimates of quantities of broadleaved species in British woodlands over 0.5 hectares in size, with special focus on ash. This includes estimates of stocked area, standing volume and numbers of trees. Later estimates are available in the 50-year hardwood forecast published 2014. For information on the amount and distribution of ash trees outside NFI woodland see the Countryside Survey Report (Distribution of ash trees (Fraxinus excelsior) in Countryside Survey data) at http://www.countrysidesurvey.org.uk . This report includes small copses of less than 0.5 hectares, linear features containing trees less than 5 metres in width (including hedgerows and lines of trees) and individual trees (including some veterans). The extent of the top ten broadleaved tree species, including ash, in copses less than 0.5 ha is included in the Countryside Survey report.
