Ancient Tree Survey
Lidia P'ng,
Heath Hands Administrator
Some of the ancient and the largest trees on
Hampstead Heath have been surveyed in the past but there never was a thorough
and complete ancient tree register. Importantly, many trees remained
unrecorded. Not any longer. On 9 March 2002, Jeremy Wright, a
keen tree enthusiast and Heath Hands volunteer, together with Deborah Wolton,
Heath Hands trustee and joint survey co-ordinator, launched a comprehensive
survey to record various aspects of the ancient trees on the Heath.
The ambitious survey, fully supported by the
Heath Management Committee, was to follow the trees marked on the 1870 Ordnance
Maps, with the exception of Kenwood, where English Heritage already have a
detailed tree management system. Teams of volunteers planned to locate each
tree, identify the species, measure its girth and note down a myriad of
important features. Is it a part of the ancient hedgerow or boundary line?
Has it been pollarded or coppiced? Does it harbour algae, lichens, moss or
fungi? Do bats roost in its crown? Altogether, some 26 characteristics of each
tree have been recorded. The aim of this detailed survey was to assist the
Corporation of London to improve the management of the veteran trees and their
surroundings, and most importantly, help to plan the next generation.
Following the successful launch and
throughout the initial training and preparation, over 40 volunteers learnt how
to identify trees in winter and how to record information on the tricky survey
sheets. The Heath was then divided into 9 areas and 7 teams of volunteers set
out to work at their own pace. At the same time the joint co-ordinators Deborah
and Jeremy kept a watchful eye on the progress of the survey and answered
volunteer queries. Remarkably, over 790 trees were recorded in the first 14
months. Many were oaks between 200 and 300 years old, but a few were probably
400 years or more. The survey also uncovered some impressive specimen of
beeches, horse chestnuts and poplars. The numbers of trees surveyed in each area
are shown here:

It soon became clear that in order to
handle and analyse the large amount of collected data, computer assistance was
essential. Heath Hands have therefore designed a specialised database system.
Following a short training session in November
2003 a group of enthusiastic
volunteers went ahead and entered the information on the database. This mammoth
task was successfully completed by early March 2004.
All in all more than 40 volunteers
worked on the ancient tree survey project contributing over 800 hours.

What next? The Corporation
of London has already acquired MapInfo, a computerised
mapping system for the Heath. Shortly, the ancient tree database should be
imported into MapInfo and printed on detailed maps. The trees could now be
revisited and their status checked in more detail. Then the database records
will need proof-reading and correcting. In short, there is still plenty of work
to do before Phase 1 is completed. And looking ahead there is always Phase 2…
Whitestone Garden
Whitestone Garden is an oasis of green
abutting Heath Street, close by Whitestone Pond on the edge of Hampstead Heath.
The garden was open to the public on 24 July 2003, following an extensive
renovation and re-landscaping by the volunteers.
Actually a part of Hampstead Heath, this
tiny sliver of land was formed more as an urban streen than as an open space.
It housed public conveniences until they were demolished in the 1990s. The
area remained overgrown and derelict until the Corporation of London invited
Heath Hands to help with reclaiming the area for public use.
More than 60 volunteers gave over 600 hours
of labour to transform the derelict, vandalised corner into an attractive
addition to Hampstead Heath. The work began in March 2001 and took more
than two years to complete.
This green gateway to the Heath includes a
wide variety of native and ornamental plants, rustic seating and is open from
8am to sunset every day.
