Enhancing/modifying a deer fence (in black grouse and capercaillie core areas)

This item is available when you are erecting a new deer fence or when you are modifying an existing deer fence in Black Grouse and Capercaillie core areas. This capital item includes fence visibility marking materials, including droppers and woodwork.

When modifying an existing fence, you must ensure that the fence line is capable of taking the extra strain, has an appropriate top wire and has struts in appropriate positions. All fencing woodwork should be treated.

You can find further details on the specifications, including diagrams, in the Forestry Commission Research Technical Guide: Forest Fencing (2006) at: http://www.forestry.gov.uk/PDF/fctg002.pdf/$FILE/fctg002.pdf

The core areas reflect the known Scottish distribution of Capercaillie and Black Grouse. These areas are defined and updated by RSPB and maps are available from Forestry Commission Scotland, Scottish Natural Heritage and RSPB.

Your local Capercaillie/Black Grouse project officer, in conjunction with the RSPB, can provide advice on the siting of fences to reduce potential problems.

For full height woodwork:

  • Use chestnut paling and sawn softwood droppers in 1.8 metre x 9 metre rolls and 4 spun wires. You should use a maximum spacing of 15 centimetre between pales/droppers close to lek sites and 30 centimetre spacing elsewhere, especially in exposed locations.
  • In areas where protection against roe deer is required, you should use a maximum spacing of 15 centimetres.
  • The top of the paling must reach the top of fence - no line wires should remain above the paling.
  • 2.6 metre deer stakes (treated & round) at 6 metre spacing with paling wires stapled to posts once strained.
  • Struts and thrust plates at 12 metre spacing.
  • Treated strainer posts and stays at 100 metre spacing.
  • Use 3 line wires either High Tensile 3.15 millimetre or spring steel 2.65 millimetre. Paling wires are to be attached to top and bottom line wires alternately every metre with stainless steel sack-ties, hog rings or line ties.

For half length woodwork:

  • Use chestnut paling and sawn softwood droppers in 1.0 metre x 9 metre rolls and 3 spun wires. You should use a maximum spacing of 15 centimetre between pales/droppers close to lek sites and 30 centimetre spacing elsewhere, especially in exposed locations.
  • In areas where protection against roe deer is required, you should use a maximum spacing of 15 centimetres.
  • Paling is to be placed as the top half of fence, above rabbit or rectangular net. The top of the paling must reach the top of fence - no line wires should remain above the paling.
  • 1.67 metre (5'6") treated and round posts at 6 metre spacing.
  • 2.6 metre deer stakes (treated & round) at 6 metre spacing with paling wires stapled to posts once strained.
  • Struts and thrust plates at 12 metre spacing.
  • Treated strainer posts and stays at 100 metre spacing.
  • Use 3 line wires either High Tensile 3.15 millimetre or spring steel 2.65 millimetre. Paling wires are to be attached to top and bottom line wires alternately every metre with stainless steel sack-ties, hog rings or line ties.
