1.3. Hedging


Buckden, SD 946757

LENGTH: 538m

March 2000

COST: £5.42/m


This technique was used to enhance existing hedges, which were in poor condition, with many gaps in the original hedge lines, and occasional mature trees and shrubs and remnants of dry stone walling. Restoration of hedges aimed to provide areas where animals, such as otters, could lie up and obtain protection and cover as well as landscape enhancement.

Three field boundary lines, near to the river, were fenced and planted with hedge plants and hedgerow trees, using British provenance plants from north of England sources. Spiral guards were provided to protect from rabbits and deer.



Double lines and, where adjacent to a roadside wall, a single line of stockproof fencing were installed. For the double fencing, a width of 1.5 metres was left between the hedge transplants and the fencing on either side. The fencing was erected in accordance with BS1722. HT8/80/15 netting was used and galvanised wire, complying with BS4102.

One row of barbed wire was placed across the top. Straining posts were a minimum diameter of 150mm, 2.15m long and spaced at no more than 100m intervals. Struts were no less than 80mm diameter, 1.9m long, and notched into the straining post at an angle of no greater than 45 degrees. They were anchored into the ground. Intermediate posts were 65mm diameter, 1.7m long, spaced at intervals no greater than 3.5m.


Hedge transplants were strong, 45-60cm high, planted in staggered double rows 30cm apart. The distance between the plants was 30cm, giving 7 plants/m. The planting mix used was 40% hawthorn Crataegus monogyna, 20% hazel Corylus avellana, 28% blackthorn Prunus spinosa, 7% dog rose Rosa canina and 5% holly Ilex aquifolium. Ash Fraxinus excelsior and rowan Sorbus aucuparia trees were placed at approximately 30m intervals. Clear, spiral guards 600mm in height were placed around individual hedge transplants and trees.

60m of hedgelaying was carried out along the roadside.
