Site Description General description:
Linear stretch of Ancient Semi Natural Woodland and Plantation Ancient Woodland that borders part of the
river Wansbeck and the Bothal Burn.
Site parking and access:
The site is privately owned, however public footpaths run adjacent to the river. The public footpaths are well
used by dog walkers.
Description:
Bothal Burn and the River Wansbeck is a site supporting Ancient Semi-Natural Woodland (ASNW) and
Plantation Ancient Woodland (PAW) along the Bothal Burn and River Wansbeck. It lies immediately adjacent
to Wansbeck River - Chapel Woods Local Wildlife Site.
The site boundary includes dwellings and gardens at present. It is suggested that these be removed from the
boundary as these do not meet the guidelines for Local Sites.
The site is broadly in four sections; the area west of Bothal Mill Bridge; West Wood that runs along the south
of the river Wansbeck; Bothal Banks Wood and Welbeck Wood north of the river Wansbeck, south of the
Bothal Bank road; and Park Wood, north of Bothal Bank road. The woodlands are all situated on steep slopes
leading down to the watercourses.
The area of west of Bothal Mill Bridge is part ASNW and part PAW. It is an area of mixed woodland where
coniferous species represent a small percentage of the overall canopy cover. The canopy is dominated by
sycamore, with locally frequent areas of beech, as well as some alder and crack willow along the river bank
and yew, oak and silver birch elsewhere. Both bird cherry and wild cherry were also occasionally recorded.
The understorey is predominately hazel and hawthorn, with some blackthorn, wych elm, elder and holly.
Whilst the understorey is diverse it is not dense and appears that regeneration of both the shrub layer and
canopy species is not extensive. This maybe a result of deer browsing.
The groundflora layer is well developed and species rich, supporting at least 13 Ancient Woodland Indicators
(AWI) including English bluebell, ramsons, hard shield fern, locally abundant ramsons and locally frequent
woodruff. Non-native species are a threat to the groundflora including garden escapes such as snowberry and
fringe-cups and listed species on Schedule 9 of the Wildlife and Countryside Act 1981 (as amended) (see
below).
West Wood that runs along the south of the river Wansbeck is also an area of ASNW. This area of woodland
is perhaps the most influenced by the adjacent Bothal Castle and gardens. The canopy layer, whilst mostly
dominated by broad-leaved species, also includes species of cypress that were presumably part of wider
ornamental gardens of the estate. The understorey is predominately hazel and hawthorn and is well
developed. The groundflora, whilst diverse, is not as uniformly dense as that seen in the western portion of
the woodland, particularly towards the Bothal Bridge area. Despite this, West Wood supports at least 13 AWI
including locally frequent areas of wood anemone and ramsons.
Bothal Banks Wood is situated north of the river Wansbeck and south of Park Wood (described below). This
woodland is mixed and supports frequent sycamore and beech, with some oak and larch, amongst other
species. The understorey varies across the area; towards the Wansbeck it becomes more dense and is
frequently dominated by bird cherry and hazel. The groundflora also varies, but is most dense along the
Bothal Burn and towards the main river. The groundflora is, like the rest of the site, dominated by ramsons
and bluebell, but also supports Lords and Ladies, primrose, wood sorrel and bramble. In total Bothal Banks
Wood was recorded to support 11 AWI.
The woodland runs, in a narrow strip along the Wansbeck river towards where it joins a younger piece of
woodland the Welbeck Wood. This is a younger mixed woodland that also supports some AWI. A full survey
of this area was not carried out.
Park Wood is the woodland that borders the Bothal Burn and is the most northerly part of the Local Site. It is a
mixed woodland dominated by sycamore with occasional beech and oak. The groundflora is dominated by
sections of English bluebell and ramsons, but also supports another 10 AWI including wood sedge and
sanicle. The understorey is sparse but dominated by hazel and hawthorn. There is little re-growth of the
canopy species or understorey possibly a result of deer browsing again. There is some influence from
surrounding properties on the groundflora and yellow archangel (variegated form), as well as Solomon’s seal,
was recorded. Himalayan balsam was also noted in a dense patch at the very northern most point of the site.
Whilst this poses a threat to the native groundflora it appeared to be contained to an area of disturbed ground
just outside of the woodland.
Non-native invasive species (rhododendron*, yellow archangel*, Himalayan balsam*, giant hogweed* and
Japanese knotweed*) were recorded throughout the site, although not uniformly. Along the river banks
Himalayan balsam is locally dominant. Giant hogweed is also along the river banks, although to a lesser
extent. Japanese knotweed was recorded in the West Wood, to the east of Bothal Mill Bridge. Rhododendron,
presumably a legacy of formal gardens associated with Bothal Castle, was also found in West Wood. Yellow
archangel (variegated form) was noted in the western portion of woodland and Park Wood.
Other ornamental species were also found, including salmonberry, most of which were in the West Wood.
*Non-native invasive species listed on Schedule 9 of the Wildlife and Countryside Act 1981(as amended).
Additional Features of Note (refer to Ratcliffe criteria where appropriate):
Heron, chiff chaff, kingfisher, tawny owl, great tit and red squirrel were recorded during the survey.
The river Wansbeck is known to support white-clawed crayfish.
An active badger sett was noted.
Management Issues:
• Invasive non-native species threaten the integrity of the woodland and potentially the structure of the
river banks.
• Non-native coniferous trees reduce the cover of native groundflora
• Grey squirrel have also been reported in the woodland. These are likely to outcompete red squirrels
and potentially carry squirrel pox.
Conservation actions:
• Removal of non-native species would support native groundflora and reduce bankside erosion on the
river.
• Staged removal of non-native conifers and replacement with native broad-leaved trees would be
beneficial to the groundflora, however the coverage of conifers is not great and as such is not a
significant issue
• Trapping of grey squirrels will be beneficial to red squirrels.
Notes for next survey
Access to the Choppington Woods part of the site was not possible and would benefit from survey.
A full survey of Welbeck Woods is required.
Ponds near Welbeck Woods would benefit from survey.

Site Evaluation Against Guidelines Version of criteria tested against: November 2012
Criteria Site
Woodland ASNW and PAW site with 16 AWI recorded and pockets of semi-natural canopy.
Site boundary has been established using: existing field boundaries/watercouses/roads/other on the ground
feature. Please specify…Woodland blocks and roads
For full species list see Appendix
Selection judgement
Decision
Designate the site as a LWS? YES x NO
Boundary alteration? YES x NO
Retain for further survey/management? YES x NO
Reason why:
The site supports ASNW and PAWs with over 10 AWI and pockets of natural canopy.
Suggested boundary alteration to exclude dwellings and roads.
Further survey is needed on Choppington Woods, Welbeck Woods and the ponds next to Welbeck Woods.
