Appendix A White-clawed Crayfish Survey
Appendix B Peregrine Survey
The findings of the environmental impact assessment for the redevelopment of Midland Quarry[1] are presented in the Environmental Statement, produced by Wardell Armstrong (2002[2]). Subsequently, Entec conducted a white-clawed crayfish (Austropotamobius pallipes) survey and a peregrine (Falco peregrinus) survey (see Appendix A and Appendix B respectively).
This report was prepared in response to comments raised by
This report provides a description of the sites ecological and geological features, landscape and recreational open spaces. It provides an evaluation of the sites and a description of the proposed development. This report provides an outline of the approval to be taken when further details are submitted for planning conditions 28 and 29, and includes the surveys for conditions 30 and 31 that relate to the sites ecology and geology:
28. No development shall commence until full
details of ecological and geological features to be retained have been
submitted to and approved in writing by the Council. These details shall include for:
(i) the retention of the marshy grassland in
the area to the south of
(ii) a wildlife corridor of not less than 8 m wide either side of
the existing or diverted watercourses Bar Pool Brook and Holly Stiches Brook,
unless otherwise agreed in writing by the Council;
(iii) the retention of the geological features
on the quarry face to the north of the quarry void.
No ecological or geological areas other than
those agreed shall be removed and no development shall commence until details
of the protection and enhancement of the retained areas and details of
mitigation for the areas to be lost have been submitted to and approved in
writing by the Council.
29.
The
ecological mitigation and protection measures agreed in relation to condition
28 shall not be carried out other than in accordance with phasing details
approved in relation to condition 5.
30.
No
development shall commence until a survey to ascertain the presence of crayfish
in the quarry pond has been carried out and this together with measures
required for the protection of any crayfish found have been submitted to the
Council. If the Council determines that
such measures are necessary, the development must be carried out in full
accordance with a scheme of protection measures approved in writing by the
Council.
31.
No
development shall commence until a survey to ascertain the presence of
peregrine falcons in the site has been carried out and this together with
measures required for the protection of any falcons found have been submitted
to the Council. If the Council
determines that such measures are necessary, the development must be carried
out in full accordance with a scheme of protection measures approved in writing
by the Council.
For the purpose of this report the site has been divided into eight compartments that are indicated in Figure 1.1.
Habitats and rock exposures of respective nature conservation and geological value are indicated in Figure 2.1. The sites ecological and geological features, landscape and recreational open spaces are described for each compartment in the following sections.
The land south of
Holly Stiches Dell comprises steeply sloping woodland either side of the Holly Stiches Brook. The woodland is dominated by ash (Fraxinus excelsior), with occasional pedunculate oak (Quercus robur), hawthorn (Crataegus monogyna), elder (Sambucus nigra) and goat willow (Salix caprea). This vegetation type is most similar to W8e Fraxinus excelsior - Acer campestre - Mercurialis perennis woodland Geranium robertianum sub-community (Rodwell, 1991[3]). There are several footpaths within the Dell.
The land south of
scrub;
underscrub;
rough grassland;
tall herb vegetation; and,
swamp.
An overgrown hedgerow with ash standards occurs immediately
south of
There are various thickets of underscrub to the south of
There is an extensive amount of rough grassland to the south
of
The marshy interface between the rough grassland and the swamp supports some tall herb vegetation is dominated by great willowherb (Epilobium hirsutum), common nettle (Urtica dioica), creeping thistle with occasional meadowsweet (Filipendula ulmaria). Around the swamp margins are patches of jointed rush (Juncus articulatus) and hard rush (Juncus inflexus). This vegetation type is most similar to OV26d Epilobium hirsutum tall herb vegetation Arrhenatherum elatius sub-community (Rodwell, 2000[5]).
There is an area of swamp vegetation adjacent to the Holly
Stiches Brook, south of
The land south supports a hedgerow and marshy grassland that have not been managed. Consequently, much scrub has encroached the grassland and a swamp has established where the ground is waterlogged.
The land between Bar Pool Brook and Holly Stitches Brook has been subject to considerable earth works earlier this year. To the north-east of the Bar Pool Brook tall ruderals and ephemeral/short perennial vegetation has begun to colonise the bare ground.
The Bar Pool Brook and Hollystitches Brook support common marginal plants, that include: fools water-cress (Apium nodiflorum), great willowherb, reed canary-grass (Phalaris arundinacea) and branched bur-reed (Sparganium erectum). Aquatic plants are sparsely distributed and include Nuttalls waterweed (Elodea nuttallii) and common duckweed (Lemna minor).
A fragmented overgrown hedgerow and associated scrub occurs on the south-west bank of the Bar Pool Brook. The hedgerow and scrub is most similar to W21a Crataegus monogyna - Hedera helix scrub Urtica dioica sub-community.
Midland Quarry is a deep void with associated surrounding cliffs and is wholly located within the site boundary. The rock strata within the quarry void is particularly well exposed.
The Quarry is developed within a ridge of Cambrian age rocks referred to as the Hartshill Sandstone Formation. The Hartshill Sandstone Formation (also known as Hartshill Quartzite) consists of five members and bedding dips steeply at 41o towards the south-west. The Tuttle Hill Member outcrops over the northern part of the Quarry with the Jees Member, Home Farm Member and Woodlands Member exposed in narrow bands along the south-west rim. The Hartshill Sandstone Formation is overlain to the south-west by the Purley Shale Formation which is also of Cambrian age.
A lamprophyre sill of Ordovician age occurs across the northern part of the Quarry. The sill was intruded parallel to the bedding of the Tuttle Hill Member that dips steeply to the south-west at 40-60o. The sill has a north-west to south-east orientation along the north rim of the Quarry and, can be seen in the north-eastern Quarry face.
The steeply dipping Cambrian and Ordovician rocks are unconformably overlain in the eastern part of the Quarry by the Triassic age Bromsgrove Sandstone Formation. The unconformity is exposed in the north-east Quarry rim. The Bromsgrove Sandstone Formation dips at 22o towards the north-east. The Bromsgrove Sandstone is overlain to the north-east by Mercia Mudstone which is also of Triassic Age.
The land north-east of the Bar Pool Brook was subject to considerable earth works during early 2003. The bund was stripped of grassland and scrub vegetation and mainly comprises bare ground that is in the process of being colonised by tall ruderals and ephemeral/short perennial vegetation.
A section of the
The Dumbles is a public open space that is situated between
hedgerows;
scrub;
underscrub; and,
grassland.
There is an overgrown hedgerow around the western boundary
of the site, which is parallel to the
Scrub and establishing plantation woodland occur along the
eastern boundary of the site, which is adjacent to the
The underscrub is dominated by bramble with occasional dog rose. This vegetation type is most similar to W24a Rubus fruticosus - Holcus lanatus underscrub Cirsium arvense sub-community.
The grassland supports false oat-grass,
The
No species that are afforded legal protection[7] or are otherwise notable have been recorded at the site.
There are no ecological or geological/geomorphological features of international or national importance within or adjacent to the site boundary. However, there are six non-statutory designated nature conservation sites that are located either within or adjoining the boundary. Midland Quarry has been designated a Regionally Important Geological Site (RIGS) by the Warwickshire Geological Conservation Group.
The six nature conservation sites listed in Table 3.1 are
referred to as Wildlife Sites and Wildlife Corridors by
The Schedule to accompany the Local Natural Environment Plan and the Green Map (Nuneaton and Bedworth Borough Council, 1999[8]) classifies non-statutory sites into Grades A, B and C.
Grade A sites include LNRs, pSINCs and other sites which are the best example of their habitat type or geological/geomorphological features (e.g. RIGs) in the Borough. We consider these sites to be higher than parish importance for nature conservation;
Grade B sites include those slightly below pSINC, Regionally Important Geological Sites and best example habitat type status. We consider these sites to be of parish importance for nature conservation;
Grade C sites include other areas of ecological, geological/geomorphological or recreational importance. We consider these sites to be of local importance for nature conservation.

The ecological, geological, landscape and recreational value of each compartment is described in the following sections.
The land south of
The Holly Stitches Dell Wildlife Site supports semi-natural broad-leaved woodland and stream habitats.
The land between the Holly Stiches Dell Wildlife Site and the Bar Pool Brook Wildlife Site supports an overgrown hedgerow, scrub, semi-improved neutral grassland and marshy habitats. The marshy habitats comprise a swamp that it surrounded by tall herb vegetation and the Holly Stiches Brook.
The land between the Bar
Pool Brook Wildlife Site and
The Midland Quarry RIGS has been designated because it exhibits the following geological features:
an unconformity between the Cambrian age Hartshill Sandstone Formation (with an intrusive lamprophyre sill) and the overlying Triassic age Bromsgrove Sandstone Formation, which is most visible in the north-eastern face of the Quarry void; and,
the steeply dipping strata of the Hartshill Sandstone Formation (specifically beds of the Tuttle Hill Member), which is most visible in the south-western corner of the Quarry.
The Midland Quarry Wildlife Site contains cliff ledges, scattered trees, scrub, patches of tall herb vegetation and ephemeral/short perennial vegetation.
The
The Dumbles Environment Area is an open space with opportunities for local people to participate in informal recreational activities and to enjoy wildlife.
The Railway Embankment off Vernons Lane Wildlife Corridor supports scrub habitat. The railway is a landscape feature that enables the movement of plants and animals to the site.
The retained ecological and geological features, proposed structural landscaping and recreational open spaces are indicated in Figure 4.1. The Site Masterplan (see Figure 4.1) indicates the proposed INF 3 access, approximate extent of DEV 5 development plot and connection to Hillary Road that are all subject to detailed design by Warwickshire County Council. The significance of habitats that will be lost or damaged by development are described in the following sections.
The proposed construction of the site access road INF 3 will result in the partial loss of a hedgerow, scrub and occasional trees.
We consider that the partial loss of habitat in this area not to be significant.
The proposed construction of the site access road INF 3 will result in the partial loss of scrub and trees around the boundary of Holly Stitches Dell. . The Holly Stitches Brook will be protected from construction activities.
We consider that the partial loss of habitat in this area to be of minor significance.
All of the marshy habitat within Area 3 will be retained. Subject to land drainage consents from the Environment Agency, it is proposed that a section of the Holly Stiches Brook will be diverted into the Bar Pool Brook.
No significant ecological effects are predicted.
The proposed development will necessitate the diversion of the Holly Stiches Brook to the Bar Pool Brook in an open channel (subject to land drainage consents from the Environment Agency). It is proposed that the Bar Pool Brook will be re-profiled (subject to land drainage consents from the Environment Agency) to accommodate water from the Holly Stiches Brook. The re-profiling works would be conducted in a manner to minimise adverse ecological effects to the Bar Pool Brook Wildlife Corridor.
We consider that the partial loss of habitat in this area to be of minor significance.
The proposed development of DEV 5 may, subject to detailed design, may encroach onto the marshy habitat within Area 5. If the detailed design shows encroachment onto the marshy habitat further ecological surveys may be required. However, it is intended that the proposed development of DEV 5 will avoid the marshy habitat in its entirety.
The proposed development of DEV 5 will require the removal of the overburden bund that mainly comprises bare ground. Scrub and semi-improved grassland was cleared from this bund during the winter 2002-2003. The loss of these habitats is considered to be negligible or of minor significance (Wardell-Armstrong, 2002[9]).
The proposed development of DEV 11 will also require the infilling of the eastern part of the quarry void, which mainly supports bare ground. We consider that infilling the quarry void not to be significant.
A canal footbridge is proposed to provide a pedestrian and cycle link between the DEV 11 and The Dumbles. The canal will be protected from construction activities.
No significant ecological effects are predicted.
Footpaths/cycleways will be upgraded across The Dumbles to
facilitate pedestrian access between the
No significant ecological effects are predicted.
There are no proposals for development in this compartment.
Recommendations for enhancing the sites ecological and geological features, landscape and recreational open spaces are described in the following sections, together with opportunities for habitat creation.
It is proposed that trees and shrubs will be planted at
suitable locations. The tree and shrub
species to be planted will be native and indigenous to this part of

The semi-improved neutral grassland and the majority of the
marshy habitats will be retained. New
seating and an ecological interpretation board will be provided at a suitable
location within the public open space over-looking the marshy habitats. A new footpath/cycleway will also be provided

A concept landscape plan of the Bar Pool Brook is illustrated in Figure 5.1.
It is proposed that the Bar Pool Brook should be re-profiled (subject to land drainage consents from the Environment Agency) to accommodate water from the Holly Stiches Brook. It is proposed that the re-profiled Bar Pool Brook will include meanders and pools & riffles.
The overgrown hedgerow that is adjacent to the Bar Pool
Brook will be enhanced by planting trees and shrubs. The tree and shrub species to be planted will
be native and indigenous to this part of Warwickshire. A new footpath/cycleway will be provided on
the east side of the Bar Pool Brook to link
The geological exposures on the northern side of the quarry (ENV 2) will be retained. The retained geological features include the north-east and north-west faces of the quarry which are geological conservation areas (see Figure 4.1).
A cliff-top viewing platform will be fitted with safety railings and, where necessary, also along the public access route. The viewing platform will include an interpretation board that explains the geological features of the quarry. The location of the cliff-top viewing platform is illustrated on Figure 4.1.
Native trees and shrubs that are indigenous to this part of Warwickshire will be planted around the cliff-top to enhance and integrate DEV 11 into the landscape.
The frontage of the northern side of the canal will be planted with marginal vegetation comprising of tall-herbs and trees. The plants to be stocked will be native and indigenous to this part of Warwickshire.
A concept landscape plan of The Dumbles is illustrated in Figure 5.2.
The Dumbles represents the largest public open space on the site. Part of the grassland will be regularly mown to facilitate informal recreational activities, while the remainder will be managed to enhance the floristic diversity of the sward. This will involve mowing the grassland during late summer with a mini-tractor fitted with a grass collection bucket. The collected arisings will be disposed of off-site to help reduce the nutrient loading of the soil. The reduction in nutrient loading and more frequent mowing should encourage the spread of forbs and fine grasses that are associated with MG6 Lolium perenne-Cynosurus cristatus grassland (Rodwell, 1992).
Creation of flood attenuation wetland adjacent to Holly Stitches Brook. The flood attenuation wetland will be stocked with native marginal plants that are indigenous to this part of Warwickshire.
Indigenous trees and shrubs will be planted in the gaps of
the hedgerow along the north-west boundary adjacent to the
Other enhancements will include:
additional tree planting;
additional shrub planting;
additional standard tree planting in strategic key locations;
new bound gravel footpaths;
a new reinforced grass footpath;
a new lockable gate for maintenance access and a motorcycle barrier;
a new interpretation board;
new benches and litter bins;
new timber bridges and handrail crossing the canal overflow and Holly Stitches Brook;
new steps and handrails at the canal two-path access points to the north-east and south-west of the open space;
a new cycleway access and bridge across the canal to connect with the proposed development.
No mitigation opportunities have been identified in this compartment.
The sites ecological and geological features, landscape and
recreational open spaces have been evaluated.
We consider that the majority of the site to be of negligible value for
nature conservation. However, within the
urban context of
Details of ecological and geological features that will be lost to development or retained are described. Part of the marshy habitat may be lost to enable construction activities that are associated with DEV 5. It is proposed that the Bar Pool Brook will be re-profiled to accommodate water from the Holly Stiches Brook. The re-profiling works will be conducted in a sensitive way to minimise adverse ecological effects to the Bar Pool Brook. The earth bund situated north-east of the Bar Pool Brook will be removed in order to facilitate the construction of DEV 5. The proposed construction of DEV 11 will necessitate the infilling the eastern end of the quarry void. The geological conservation areas in the north-east and north-west faces of the quarry will be retained. Opportunities for mitigation, including the enhancement and creation of new habitats are described.
Overall, the proposed development will result in a better
site for wildlife than it does at present.
The habitats along the Bar Pool Brook will be enhanced in order to
provide a movement corridor for wildlife, between the
The proposed development will also provide open space areas
for informal recreational and for local people to enjoy wildlife. The main open space areas that will be
enhanced include The Dumbles and the north-west side of the
Future detailed planning will determine whether there is a need for further site investigations.

30. No development shall commence until a survey to ascertain the
presence of crayfish in the quarry pond has been carried out and this together
with measures required for the protection of any crayfish found have been
submitted to the Council. If the Council
determines that such measures are necessary, the development must be carried
out in full accordance with a scheme of protection measures approved in writing
by the Council.
Licensed crayfish surveyor Dave Ottewell of the Environment
Agency conducted the survey at Midland Quarry.
The Environment Agencys standard crayfish survey methodology was used
to determine presence. The methodology
involved the use of two 100m lines each fitted with 10 baited traps. The traps were fixed at 10m intervals,
allowing a large section the ponds depth profile to be covered. The traps were set during the afternoon of
No crayfish were found within the pond at Midland Quarry.

Peregrine Survey
2 Pages
This report was prepared in
response to comments raised by
31. No development shall commence until a survey to ascertain the
presence of peregrine falcons in the site has been carried out and this
together with measures required for the protection of any falcons found have
been submitted to the Council. If the
Council determines that such measures are necessary, the development must be
carried out in full accordance with a scheme of protection measures approved in
writing by the Council.
The peregrine surveys were conducted by Entec ecologist Stephen
Carter. The survey methodology involved
three site visits during the peregrine breeding season. The site surveys were conducted on 22nd
April, 30th May and
No peregrine nests were found on the cliff faces at Midland Quarry.
Feral pigeons (Columba livia), a favoured item of peregrine prey, were found to be nesting on the cliff ledges within the quarry.
The only raptors recorded during the survey were a female kestrel (Falco tinnunculus) and a pair of sparrowhawks (Accipiter nisus) flying over the quarry on 22nd April and 30th May respectively.
We consider that the proposed development at Midland Quarry
will not effect peregrines. The presence of feral pigeons within quarry
is likely to provide a foraging resource for peregrines that are known to nest
nearby. The proposed development at
Midland Quarry is unlikely to have a significant effect on nesting feral
pigeons, which are a common breeding bird in
