While
George Peterken in 1977 did recognise wood-pasture and parkland as distinct and
important forms of ancient woodland, they were largely ignored in much woodland
conservation policy and practice until the late 1980s. Then during the 1990s interest in veteran
trees exploded; they were recognised not just as important habitats for
lichens, deadwood beetles, fungi etc,
but as worthy of conservation in their own right. The need for a different
approach to management, compared to coppice and high forest stands, became more
widely appreciated – in particular the critical role of grazing in creating
relatively open mosaics of trees, scrub and grass/heath. The inclusion of
wood-pasture and parkland as one of the priorities under the UK Biodiversity
Action Plan (http://jncc.defra.gov.uk/page-5706)
further stimulated research into their distribution and conservation. We now
appreciate that it is much more widespread than had previously been thought,
but that in turn raises more questions about how it can be maintained. While
the most extensive areas, such as the New Forest, Epping Forest, Windsor Great
Park , Sherwood
Forest are covered by SSSI (Site of Special Scientific Interest)
protection there are many other sites throughout the country whose significance
may not have been recognised. Hence much work has gone into surveys over the
last decade.

The surveys being undertaken to
identify the location and extent of wood-pasture and parkland in England are due
to be published shortly. Projects have been underway for a number of years at a
national level to produce a provisional inventory for wood-pasture and parkland
for the whole of England .
A number of datasets was used to compile the provisional inventory, including
the Woodland Trust Ancient Tree Hunt whose volunteers have now gathered 100,000
records of veteran trees across the UK and local specialists who shared
their knowledge about their patch.
Using aerial photographs backed
up with evidence from historic maps, over 156, 000 ha of the habitat has been
identified in England . Our challenge now is to ensure any new sites
identified through this process are effectively managed, which will include
ensuring the next generation of veteran trees is growing on or near the site
and that the open habitat around the trees is being managed effectively.
