Below are links and extracts from some literature on the subject, mostly from Forestry Commission
sources. I hope anyone interested in being involved will find them useful reading.
In the light of the apparent policy, [Check the last paragraph] it's even possible that FC may have to pay to bring the coppice back into rotation,
and we should ensure that we (or members) are in a position to participate in any such programme.
Beginning about 2000 or so, for three years we began the restoration of
coppice working in part of the ancient coppice area on Potterland Hill. We cut three successive
coupes and protected them with dead and laid hedge materials, and they were doing pretty well. Sadly, in 2004, thinning contractors destroyed our protective efforts and reduced our enthusiasm.
I've recently been checking out the felled areas, and reckon that the first coupe has sufficient re-growth and is ready for felling again.

I hope to get the Forestry Commission to agree to let us get back in sometime this winter to
harvest this coupe, and possibly to have a go at starting restoration on another coupe in another part of the area.
We can then use the material for a course in the Spring gathering at Taliesin.

Coppice woodlands
Background
Coppice was the traditional form of silviculture practised in many woodlands in lowland Britain, and the estimated areas of simple coppice, and coppice with standards, has been declining for at least a century. However, during recent years there has been a revival of interest in this form of management.
Coppice woodlands often have a potentially high conservation value, but many of those that remain are neglected, and require management in order to retain their character and biodiversity. Whilst there has been much interest in the ecology of coppice woodlands there has been little systematic study of the silviculture of either coppice stools or woodlands.

"Restoration of Neglected Hazel Coppice"
by Ralph Harmer, March 2004
SUMMARY
The biology and silviculture of hazel coppice woodlands are briefly explained. Practical procedures for management of
stools are described and the results of a recent case study on growth and yield are presented. The month of felling, or height
at which stools are cut, has little long-term effect on either mortality of stools or regrowth of coppice shoots. Adequate
protection from browsing animals is necessary to ensure success. Excessive browsing will reduce economic potential and
may kill stools.

MANAGEMENT OF COPPICE STOOLS by Ralph Harmer
Abstract
Coppice is a traditional method of woodland management in which stools are cut on a regular cycle; this
provides a valuable supply of small-wood and a variety of habitats for wildlife. This Note describes
management of the stools which make up traditional, mixed-species coppice. The information presented
includes establishment, method of cutting, position and timing of cut, protection from browsing and
management of standards.

Forestry Commission Practice Note 14.
Restoration of native woodland on ancient woodland sites (PDF-1975K)
This Forest Practice Guide provides advice on why, where and how to restore PAWS.
The purpose of this Guide is to give Best Practice advice to owners and managers on the
restoration of native woodland on ancient woodland
sites which have been planted with non-native species
since the 1930s. These ‘non-native PAWS’ form
around 60% of the total PAWS resource which
is 220 000 hectares. Ancient woodland sites are
those included in the inventories of ancient
woodland which were based on the oldest
reliable national information. In England and
Wales this goes back to 1600; in Scotland to
1750....
A framework allows the assessment of restoration potential of a site or ranking of a range of sites.
Restoration methods are discussed with advice given on the protection of ancient woodland remnants and development of native woodland.
And, the FC grant policy on restoration (in case we found ourselves in an ownership situation....(stewardship grant may be applicable to Taliesin))
This note sets out how the Scottish Forestry Grants Scheme will be used in relation to
future management of plantations on ancient woodland sites (PAWS), and defines the
meaning of ‘priority sites’ in the context of Stewardship 3 grant. The Forestry Practice Guide
‘Restoration of native woodlands on ancient woodland sites’, published in April 2003, [see above] sets
out options for managing these sites and should be used for more detailed practical
guidance.
Restoration of lowland conifer PAWS
Ralph Harmer and Andrea Kiewitt (PDF-1299K)
Brief report of vegetation changes and seedling development that occurred following thinning in a Corsican pine PAWS.
From the introduction:
About 40% of ancient woodland that
existed in the 1930s was converted to plantations, mostly between 1950 and 1980: these plantations
on ancient woodland sites are commonly known as PAWS. Despite intensive silvicultural practices,
the conversion of existing broadleaved woodland sites to conifers was often less successful than
afforestation. The process of conversion became a contentious issue and was abandoned in 1985
when the government’s policy for broadleaved woodlands was introduced. PAWS often retain a
number of features characteristic of the preceding native woodland, including remnants of the
ground flora, old coppice stools and veteran trees which can provide a nucleus around which a new
broadleaved woodland can be created. Restoration of native broadleaved woodland is an important
aim of current policy and a significant management objective of many PAWS. The aim of
restoration is to create the conditions needed to promote the development of native woodland over
the long term; it is a process which attempts to re-establish a functioning ecosystem by:
Restoration of upland planted ancient woodland sites (PAWS) (Ralph Harmer)
...There is currently a lot of emphasis on the use of gradual methods to convert the plantation to a native woodland using alternative silvicultural systems to clearfell. Under this ecology of upland native woodlands programme and the Lowland Native Woodlands programme, we are undertaking a number of experiments to determine the appropriate approach for a range of former woodland types....

An interesting excerpt from Part 2:
5.1. Defining native tree species
‘Native tree species’ have to be defined before we can define ‘native woodland’, but no
single definition is invariably appropriate. We generally agree on which species are
native to Britain or a region of Britain, but we also need to decide where ‘regionally-
native’ species and also ‘site-native’. We also have to consider provenance.
Native status should be seen not as a black-and-white matter, but as a spectrum of
attributes. The strictest definition would insist that a population of a species can only be
described as ‘native’ if it owes its presence wholly to natural processes, and has
descended on or near its present site from populations that were present in original-
natural forest, i.e., its provenance is strictly local. This definition is appropriate to nature
reserves and the more important ancient woods.
Elsewhere, it may be acceptable to use a wider definition. Species are recognised as
‘regionally-native’ if they have long been present and arrived by natural means, even
though many of the existing stands have been planted, sometimes using non-local
provenances. This wider definition can be refined to recognise a regionally-native
species as ‘site-native’ if it occupies ground which it would occupy naturally. Thus, for
example, sessile oak is regionally native to the NYM/HH, but probably not site-native to
deep, wet soils on floodplains. The concept of regional- and site-native species would be
appropriate for the generality of native woodlands.
A still wider definition might be appropriate in some circumstances. Species that were
introduced to the region, but which are now self-supporting are usually described as
‘naturalised’, and it is possible that they will have become genetically adapted (through
natural or forestry selection) to the site, i.e., they have developed a land race that grows
better locally than any other provenance. Since the general public would probably accept
any deciduous broadleaved tree species as native, it may be appropriate to accept
naturalised (i.e, naturally self-perpetuating) deciduous broadleaved species as de facto
natives in the less ecologically important sites, mostly recent secondary woodland.
A yet wider definition may be acceptable in limited circumstances. Naturalised
coniferous and evergreen broadleaved species may be just as self-supporting and adapted
to the site as naturalised deciduous broadleaves, but they form en masse an alien
physiognomy. In recent secondary woods, natural regeneration of these species may be
acceptable, provided it remains a minority of the stand.
In practice, there is no doubt that species such as oak and ash are regionally native and
that, for example, Douglas fir is not, but between these a few species remain ambiguous.
Where should forest managers treat them as native? In the NYM/HH, the following
solutions are recommended on the basis of historical presence, conformity with
prevailing woodland types, and ecological impacts, and in conformity with advice
previously offered by the Forestry Commission (1994):
From Forestry Commission Scotland:
Woods for Nature - Our Biodiversity Programme - 2008-2011
We have a lead role under the UK Biodiversity Action Plan
(UKBAP) for native woodland priority habitats in Scotland, and
we will continue to focus on leading delivery of the Habitat
Action Plan (HAP) targets in Scotland for expanding native
woodland area, improving the condition of existing native
woods and restoring native woods from non-native plantations
on ancient woodland sites (PAWS).
...
To help achieve HAP targets we will seek minimum annual
outcomes for the three years of this programme of 4,500ha
of expansion, 6,000ha brought into management to improve
condition (including designated and other woods), and
1000ha of non-native PAWS put into restoration toward
native woodland.
For some PAWS sites complete restoration to native woodland
will not be the best option, and partial restoration work to
safeguard and enhance remnant ancient woodland features
may be more suitable. We encourage careful consideration of
restoration options for PAWS, both in forest design plans on the
national forest estate and Forest Plans under the Scottish Rural
Development Programme.
