32   Management of ancient wood pasture   , Sites currently listed in and candidate sites for the “Inventory of Ancient Wood Pasture in Scotland” (maintained by Scottish Natural Heritage) will be eligible. This option may be adopted for ancient wood pasture sites where there are existing veteran trees and for areas which are contiguous with existing ancient wood pasture and now devoid of veteran trees but where there is historical evidence, from 1st edition 1860 maps, that such a habitat has existed.  , a   Where the open pasture element of the wood pasture is grassland, improved or unimproved, on the inbye–     Option 1     Livestock must be excluded for 6 consecutive weeks between 1st April and 15th June (inclusive);      At other times, grazing levels must be set to maintain an average sward height of between 5 and 20 centimetres, subject to a maximum annual stocking density of 0.75 livestock units per hectare;         OR      Option 2     Where the aim of this prescription would not be achieved by adopting option 1, a livestock management and grazing regime must be set out in a grazing plan to be agreed with the Scottish Ministers. Stocking rates must be set to maintain an average sward height of between 5 and 20 centimetres subject to a maximum annual stocking density of 0.75 livestock units per hectare. Where such an alternative management regime is proposed, evidence to support its adoption must accompany the application;         AND, for both options–     Pesticides, lime, artificial fertiliser, farmyard manure or slurry must not be applied to the site. However, herbicides may be applied to control injurious weeds (as defined in the Weeds Act 1959) using a weed wiper, spot treatment or hand sprayer;      Any topping must not be carried out before 31st July;      The site must not be used for supplementary feeding of stock;      Where planting of small trees will serve to extend or enhance this habitat, species appropriate to the site and, where available, of local provenance must be used;      Newly planted trees or any successful regeneration must be protected either as individual trees or in groups. The stem density within such groups will not exceed 50 trees per hectare while the spacing between them will not be less than 20 metres;      Wooden post-and-rail fencing or metal tree guards should be erected where required to maintain and prolong the life of individual veteran trees;      Provision must also be made through a deer control plan, agreed with the Deer Commission for Scotland, for the control of deer grazing;           b   Where the open pasture element of the wood pasture is acid grassland or heath on the rough grazings–   i   Livestock must be excluded between 1st November and 28th February;     ii   At other times, grazing levels should be set to maintain an average sward height of between 5 and 20 centimetres and must not exceed 0.3 livestock units per hectare;     iii   The site must not be used for supplementary feeding of stock;     iv   Where planting of small trees will serve to extend or enhance this habitat, species appropriate to the site and, where available, of local provenance must be used;     v   Newly planted trees or any successful regeneration must be protected either as individual trees or in groups. The stem density within such groups will not exceed 50 trees per hectare while the spacing between them will not be less than 20 metres;     vi   Wooden post-and-rail fencing or metal tree guards should be erected where required to maintain and prolong the life of individual veteran trees;     vii   Provision must also be made through a deer control plan, agreed with the Deer Commission for Scotland, for the control of deer grazing;     viii   Pesticides, lime, artificial fertiliser, farmyard manure or slurry must not be applied to the site. However, herbicides may be applied to control injurious weeds (as defined in the Weeds Act 1959) using a weed wiper, spot treatment or hand sprayer.     ,
 33   Spring cropping   , A site comprising arable land not in a Less Favoured Area subject to a maximum area per undertaking equal to the largest area of the Arable Area Payments Regulations 1996 eligible winter crop grown on the unit or units concerned in the 3 years prior to the year of application or 20 hectares, whichever is the lesser.  , a   Ploughing, cultivations and the spreading of fertiliser may only take place between 28th February and 15th May;     b   Between harvest and 28th February, pesticides may be applied only with the prior written agreement of the Scottish Ministers;     c   To maintain a similar area of cropped land in each year of the plan. Minor adjustments to this area may be made to allow for differences in field sizes, provided that the Scottish Ministers are given details at application stage of the field sizes.   ,
 3    ha   Marking of a deer fence to reduce bird collision.     , In areas where black grouse and capercaillie occur, to make the fence more visible and thus reduce the number of collisions, use either–     a double strip of orange barrier netting, each strip approximately 45 centimetres in width. Both strips must be secured with pig rings or wire twists at intervals of approximately 30 centimetres, on the upper and lower edges. The top of the upper strip should reach the top strand of the fence. The top of the lower strip should reach the middle strand of the fence; or      other fence marking design approved by the Scottish Ministers for this purpose.     ,
