assigned in conjunction with the Wey and Arun Trust to create

former Wey and Arun Canal at the Tannery Lane site.

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.

LOCATION PAGE 2
PHYSICAL CONDITIONS OF SITE
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.
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.

Within the Tannery Lane site two distinct habitats can be found. The ﬁrst Tan

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

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

AIMS & OBJECTIVES OF MANAGEMENT PLAN
Appraisal, explanations and methods of fulﬁlling the objectives concerning the management of
conserving the broad-leaf woodland at Tannery Lane will be deﬁned as a precursor to outlining the
work programmes to be prescribed in achieving continued enjoyment of these resources for
current users and a legacy for future generations.
CONSERVATION OF EXISTING BROADLEAVED HABITAT
Aims & Objectives
1. Enhance and maintain habitat of existing broad-leaf woodland.
2. Increase and maintain biodiversity of ﬂora and fauna of habitat.
3. Enable conditions to monitor and combat the effects of climate change.
4. Preserve traditional rural crafts.
5. Sustainable source of timber.

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

Broad-leaf woodlands are managed for several
purposes. Traditionally it concerned generating the

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.

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
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
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
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.
The thinning of standards is required every ﬁve
years to reduce the density of canopy and increase

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.
