A delegation from the City of London Corporation arrived in Spain on Thursday (1 October) as part of a visit designed to promote traditional tree management techniques.
Specialist staff from Epping Forest, Burnham Beeches and Hampstead Heath will survey and work on pollarded trees in northern Spain alongside local arboricultural experts and site managers.
The visit is a follow-up to one that took place in February 2007 when some 40 trees were pollarded using both traditional axe and modern chainsaw methods.
It is hoped that the results will improve the management of old trees in both Spain and the UK.
City of London Open Spaces Committee chair Janet Owen said: "We look forward to continuing working with our counterparts in Spain to build on our expertise in this field, which is essential to maintaining and enhancing the range of beautiful woodlands that we manage."
Conservation officer Helen Read added: "Epping Forest and Burnham Beeches are gradually re-introducing traditional management techniques, such as grazing and pollarding, to ensure that the veteran trees and their associated flora and fauna survive for future generations to enjoy."
The delegation will return on Friday (9 October).
