  3. 3. LOCATION Located within the Surrey Hills Area of Natural Outstanding Beauty. The site is directly south of Tannery Lane Bridge in the Parish of Shalford. The area is accessible by vehicular traffic by country roads via the A281 Horsham Road to the west. The railway station at Shalford travels between Guildford and Dorking on the North Downs Line. For pedestrians, cyclists and horse riders the locale is approachable by the Downs Link which runs through the site and Tannery Lane on the northern border.

  4. 4. PHYSICAL CONDITIONS OF SITE TOPOGRAGPY The site of tannery lane lies within a shallow basin of secondary succession vegetation, gently rising from the bridge eastwards at a gradient of 1:05 per metre. To the north a former brook has been deepened to accept seasonal floodwaters within an area of Broad-leaf wood which falls down eastwards. To the south the land rises from 0.7-1.2m wets to east as an embankment that was the location of the former Horsham to Guildford railway Line., falling down to Cranleigh waters which run parallel. At the east border of the site, Cranleigh waters crosses from south to west under Gosden aqueduct before turning eastwards and continuing its route. GEOLOGY AND SOILS The Shalford area is located on Wealden Greensand, just south of the North Downs. The soils are slightly acidic and free draining. HYDROLOGY The region of Shalford is part of the River Wey’s catchment area which flows into the River Thames. The North and South Wey join at Tilford, where the Wey runs past Shalford to be joined by Cranleigh waters and the River Tillingbourne further north. PHYSICAL CONDITIONS OF SITE PAGE 3

  8. 8. HABITATS e ridg Lane B nery Within the Tannery Lane site two distinct habitats can be found. The first Tan which dominates the central section is that of Secondary succession. This is a result of the original Broad-leafed woodland being cleared to illustrate the sites potential for a pilot scheme by the Wey and Arun Trust in the re- introduction of a length of the Wey and Arun canal. The consequence of the clearance has been the greater penetration of light to the ground layer and the pre-existing soil resulting in the re-establishment of the plant community on disturbed land, towards to climax community of the Broad- leafed woodland. The existing vegetation is composed in the main by the voracious Urtica dioca (stinging nettle). Other species found within this habitat and that of the Broad-leafed woodland are displayed within the plant material section. The habitat of the broadleaved woodland surrounds the area untouched by Cranleigh the previous clearance work. The Broad-leafed woodland depicts the waters climax community which has developed through ecological succession over time, arriving at a consistent state. The woodland has matured as a product of the plant community best adapted to the conditions of the region. It could be argued however that as a Coppice and Standard woodland which has been continually harvested in the past that it too is a site of secondary succession.

  9. 9. PLANT MATERIAL Illustrated here are the main members of the plant community found within the habitats of Tannery Lane site. The examples of the trees and shrubs are those found within the Broad-leaf woodland and exhibit varieties whose timber is used in the practice of coppicing (Hazel, Willow and Alder) and those grown as standards (Oak, Beech and Ash). The annuals and perennials are a selection of the species of plants located within and around the perimeter of the habitat of secondary succession.

  12. 12. CONSERVATION OF BROAD-LEAF WOODLAND TYPES OF BROAD-LEAF WOODLAND Britain has different varieties of woodland which has evolved naturally through contrasting soil types, climate, geology and topography. Management and past land- use will also influence the sort of woodland that matures. In the main woodland is generally classed by the primary tree species growing in that particular wood. Nevertheless in reality it is unusual to find one specific species of tree prevalent and a wood will include a Varity of tree types. TANNERY LANE BROAD-LEAF WOODLAND The broad-leaf woodland at Tannery Lane can be defined as Alder-wet woodland due to the dominance of Alders which prosper on the wet soils. This type of woodland is typically located along the banks of streams, rivers or wherever poor drainage persists. The process of succession transforms wetlands into wet woodlands through siltation and evaporation, providing anchorage for tree growth. Alder woodland will climax to be superceded by Oak woodland as further drying of the soil favours a drier woodland type. Contractor: Coppice worker harvesting MANAGEMENT OF BROAD-LEAF WOODLAND branches. Ref Greenwood centre. Broad-leaf woodlands are managed for several purposes. Traditionally it concerned generating the greatest yield for economically viable products and game which operates in tandem with our aims of conservation and increased biodiversity. Indigenous British woodland was managed to provide a sustainable source of timber by coppicing woodland Tree to be Cut close Shoots rapidly Coppice ready on a rotational cycle.

COPPICING CONSERVATION OF BROADLEAVED WOODLAND PAGE 11
  13. 13. COPPICE WITH STANDARDS Coppice with Standards developed at the time of King Henry IIIV, when he declared an edict that twelve standards or mature uncut trees should be left within each acre of woodland for timber. The system combines mature standards that occupy the canopy layer creating greater visual continuity to the woodland and a selection of coppice of different ages and species to provide various types and dimensions of wood for required demand within the under-story. The system also maintains structural diversity to the under-storey and improved conditions for wildlife conservation. The coppice is managed on a rotational basis varying from 2-20 years again depending on the variety of tree and demand of wood. The short cycle increases the amount of light penetration reaching the ground layer expanding the level of biodiversity within the woodland and improving stability of the flora and fauna.

  14. 14. COPPICE WITH STANDARDS MANAGEMENT PLAN THE MANAGEMENT PLAN The process of coppicing begins each winter, between the months of November and March traditionally after the harvest when work on the COUP B land has slowed down. This season coincides with the dormant period of deciduous plant life, with trees shed their leaves to halt the process of COUP A photosynthesis and the movement of sap up the tree to protect its energy reserves and the effects of frost damage. The reduction of sap content within the wood also makes it a more efficient COUP C source of fuel when most needed. The wood is divided into a number of coups to improve the efficiency of managing the woodland. Depending on the rotational cycle which will could be between two to twenty years, the coup COUP D selected to be coppiced will have its shoots or poles cut to lengths and stacked in heaps which are customary known as a cord with each stack being known as cordwood.

COPPICE WITH STANDARDS MANAGEMENT PLAN PAGE 13
  15. 15. COPPICE WITH STANDARDS MANAGEMENT PROGRAMME The existing broad-leaf woodland at Tannery Lane site covers an area of 9200 m2 or 0.98 Hectares. It takes a Coppice worker 400 man hours to harvest one hectare of woodland, which with our site would equate 392 man hours. These hours are divided by the number of coup divisions, resulting in 98 man hours per coup on a yearly rotational basis. With the addition of a trained volunteer to reduce costs the total time required each year to harvest a coup would be 49 man hours or 6.125 days. The estimated cost for these workers would be £1010.65 per year with Coppice worker at £150 per day and volunteer with £15 expenses per day.

Higher wind speeds can lead to the increased severity, unpredictable nature and frequency of storms promoting greater damage to woodland areas. Practical responses to the threats posed by climate change cover two fundamental areas, adaptation and mitigation. Adaptation measures attempt to minimise the effects of climate change as it progresses and mitigation responses try to limit the extent of climate change. The greatest uncertainty however concerning Britain’s broad-leaf woodlands is the inability to predict the way that human society will change and in particular how effective its efforts to mitigate climate change will be.
