• We were looking to source the timber from NT
  High Peak estate, but were unable to obtain in
  time
•  all the wood used was FSC certified
• Shingles were From CSSB Cedar Shake and Shingle
  Bureau Supplied by Rawnsley Woodland Products,
  Wadebridge Cornwall
• Structural timbers and larch cladding provided by
  Arnold Lavers, Chesterfield and Timber
  Specialists, Sheffield.

46
SUSTAINABLE USE OF WOOD

• Wood products from reclaimed and/or recycled
  sources will be preferred to new wood products
  when appropriate.
• All new wood and wood products to be used in NT
  operations/retailing must come from certified
  Forest Stewardship Council (FSC) or equivalent
  sources.
• NT estate-grown wood will be preferred to other
  sources (all NT woodlands are FSC certified).
• NT wood energy schemes will be based primarily on
  properties which can provide their own wood
  (security of supply)
• Locally grown FSC/equivalent certified wood will
  be preferred, to avoid transport impacts.

47

• Use of hardwoods grown in the UK, i.e. indigenous
  species and long established species such as
  sweet chestnut and sycamore, will be promoted.
• Use of durable softwoods grown in the UK will be
  promoted for construction projects.
• Imported wood will only be used when there is no
  viable UK-grown alternative.
• New wood supplied from rare or declining species
  or forests will not be used other than in the
  most exceptional circumstances e.g. restoration
  of rare joinery etc.

48

• All wood products used by the NT must have been
  processed in such a way as to minimise energy
  use, pollution and waste.
• Wood products used by the NT must be capable of
  being re-used or recycled i.e. not have been
  treated with toxic/hazardous chemicals such as
  CCA (unless absolutely necessary), not glued or
  not nailed in ways that would prevent re-use.
• Imaginative use of wood for solid and/or
  processed products will be promoted, as
  alternative to artificial/highly processed
  materials.

49

• Initial land management suggestions
• Convert arable to pasture
• Increase area of set-aside
• Introduce field margins
• Allow improved pasture to revert to rough pasture
• Increase area of forestry (on mineral soils)
• Butall of these are not realistic
• How can we increase carbon store in arable soils?
• How can we increase carbon store in improved
  pasture?
• How can we limit loss of carbon from rough
  pasture?
• There is a lot of variation in TOC within
  land-uses Land management change rather than
  land-use change?

Current work and Year 2 Trials

• Current Identification of target sites for
  further investigation
• Year 2
• Combination of field and lab trials
• Possible trials
• Investigate target sites
• Field Monitor flux from Greenleighton mire under
  different land-uses
• Field Monitor impact of Short-rotation Coppice
  plantations
• Lab Monitor impact of adding biochar to soils
• Field Monitor the impact of grazing on mineral
  soils

Biochar lab trials

• Pyrolysis biomass heated in absence of oxygen
  produces Char (Biochar)
• Biochar Used as a soil ammendment
• Biochar More stable than unchared biomass.
  (less decomposition)
• Shown to enhance plant growth
• (more photosynthesis)
• Increases crop yields
• Lower fertiliser input needed
• Growth of bioenergy crops for biofuel
• Offsets fossil fuel use
• Sequesters C in biomass
• Produces char
• Char improves crop yield, therefore increases
  soil carbon sequestration
• Char stored in soil for 1000s of years

57
Short- rotation Coppice plantations.

• Monitoring of soil carbon flux under stands of
  varying ages and adjacent unplanted arable land.
• SRC grown and used as bioenergy. C emitted is
  carbon that has previously been sequestered,
  therefore carbon neutral
• Biochar (stable C) can be produced in the process

Can SRC be planted on arable or improved pasture
land and increase soil carbon stocks? Contacts
made with Newcastle University to monitor
plantations at Cockle Park.
