1. INTRODUCTION
This report has been prepared by Peak Ecology Ltd on behalf of Next Phase Development. It provides details of a riparian mammal survey undertaken on a stretch of the Peak Forest Canal adjacent to the existing Furness Vale Marina site in Furness Vale, High Peak. The stretch surveyed stretched from approximately SK 005 839 to SK 003 842, although land either side of this area, to a distance of approximately 50m, was also assessed for its potential to support riparian mammals.
Plans are currently being prepared for the redevelopment and expansion of the existing marina. In particular this will involve the expansion of the marina into land which is currently an overgrown pasture field.
Peak Ecology Ltd carried out an Extended Phase 1 Habitat Survey at the site in July 2013, in relation to the plans to expand the existing marina. This survey highlighted the potential of a short stretch of the canal bank to be used by water vole $UYLFROD DPSKLELRXV and there are existing records of this species on the Peak Forest Canal. Also, records of otter /XWUDOXWUD on the River Goyt, within 200m of the survey site, were returned as part of a desk study. Otter were therefore also included within this survey.
It is the objective of this survey to understand whether water vole or otter populations are using the existing watercourse and to make an assessment of the habitats present in relation to its use by these species in the future. The results from these surveys will enable informed decisions to be made to minimise any impact and identify any benefits that this development may have on riparian mammals.
2. LEGISLATION
2.1. Water Vole
Since April 2008 the water vole has received full legal protection through its inclusion in Schedule 5 of the Wildlife and Countryside Act (WCA) 1981 (as amended). This affords them protection under Section 9, as amended by the Countryside and Rights of Way (CRoW) Act (2000).
In combination, this makes it an offence to intentionally kill, injure, or take (capture) a water vole; possess or control a live or dead water vole, or any part of a water vole; intentionally or recklessly damage, destroy or obstruct access to any structure or place which water voles use for shelter or protection or disturb water voles while they are using such a place; and sell, offer for sale or advertise for live or dead water voles.
The legislation cannot provide licences for the activities listed above for the purpose of development or management/maintenance operations. Any surveys that involve catching or handling water voles will require a licence from Natural England.
Water vole are also listed as a Priority Species on the UK Biodiversity Action Plan (BAP).
1 Peak Ecology Proposed Extension to Furness Vale Marina in the High Peak, Derbyshire / Riparian Mammal Survey
2.2. Otter
Otters receive legal protection both as a European Protected Species under the Conservation of Habitats & Species Regulations 2010 (as amended), and as a Schedule 5 species with ‘full protection’ under the WCA 1981 (as amended). This legislation protects them from harm or disturbance at any time, as well as protecting their holts from being blocked, damaged or destroyed. They are also listed as a UK Priority BAP species.
3. SURVEY METHODOLOGIES
A riparian mammal survey was undertaken by Peak Ecology Ltd on 10th October 2013. The survey included a stretch of watercourse measuring approximately 400m in length. The survey was carried out from within the water, using a small boat, to allow full access to the canal banks and a thorough search for evidence of riparian mammals. A habitat assessment was also carried out.
3.1. Water Vole
Both banks of the watercourse within the survey area were searched for evidence of water vole, in line with the standard methodology (Strachan HWDO 2011).
The banks were surveyed for;
x Burrow holes,
x Latrines,
x Feeding stations,
x Footprints,
x Commuting paths within the vegetation.
3.2. Otter
Both banks of the watercourse within the survey area were searched for evidence of otter, in line with the standard methodology (National Rivers Authority 1993).
The watercourse was surveyed for;
x Spraints,
x Holts,
x Footprints,
x Commuting paths within the vegetation,

x Haul-out places and slides.
4. RESULTS
4.1. Site Description
The survey site comprised a stretch of the Peak Forest Canal adjacent and to the north of the existing Furness Vale Marina.
The eastern canal bank was reinforced with corrugated steel for the length of the survey site. Several boats were moored along this bank and there were no notable stands of marginal vegetation. The towpath was noted to be well used, with several dog walkers and joggers seen during the survey. A narrow strip of amenity grassland was present between the hardstanding of the footpath and the canal side.

The western bank of the canal was reinforced towards the southern end of the survey site, within the existing marina. It appeared to be a well used marina with the majority of berths filled during the survey. There were no stands of marginal vegetation in this section.

3 Peak Ecology Proposed Extension to Furness Vale Marina in the High Peak, Derbyshire / Riparian Mammal Survey
The north-western section was noted during the Extended Phase 1 Habitat Survey to provide the most naturalised section of bank, with what appeared to be a strip of marginal vegetation along an earth bank. However, on closer inspection during this riparian mammal survey it was noted to be comprised of dense tall ruderal and grass species, although the substrate was soft earth. Species present included cock’s foot 'DFW\OLVJORPHUDWD, meadowsweet )LOLSHQGXODXOPDULD, common couch (O\WULJLDUHSHQV, common nettle 8UWLFDGLRLFD, reed canary grass 3KDODULVDUXQGLQDFHDreed sweet- grass *O\FHULDPD[LPDDQG gypsywort /\FRSXVHXURSDHXV.
North-western bank of Peak Forest Canal, within the survey site.
4.2. Water Vole
No evidence of water vole was found during the survey.
The reinforced banks were considered unsuitable for water vole burrowing, due to the lack of soft earth. The survey focussed on the north-western bank, where the bank was comprised of soft earth. However, the dense nature of the tall ruderal species, the lack of large stands of typical marginal and aquatic plant species and the short isolated nature of this stretch of bank were considered only sub-optimal for use by water vole.
4.3. Otter
No evidence of otter was found during the survey.
There were no large overhanging branches or tree roots that would provide ideal holt sites or laying-up areas. However, otter are known to use the River Goyt, which occurs within approximately 200m of the Peak Forest Canal at its closest point in this area. Otters could therefore use the canal as part of their wide home range and their occasional passage through the site cannot be ruled out.

5. EVALUATION AND CONCLUSIONS
5.1. Evaluation
As there is no evidence of water vole or otter within the surveyed stretch of the canal and only limited opportunities for either species, direct impacts to protected riparian mammals are considered unlikely.
The sub-optimal nature of the habitat present suggests that water voles are unlikely to use this area in the future, although it is likely that they will continue to use the wider canal area. A pre- works check for water voles is however recommended, as a precaution. Site workers should remain vigilant for water voles during any work on the site and in the unlikely event that this species is seen within the working area, work should be stopped whilst further advice is sought from an appropriately experienced ecologist.
Although direct impacts to otter are considered unlikely, the occasional passage of this species through the survey area cannot be ruled out. It is therefore recommended that contractors remain vigilant for this species at all time, although work should be restricted to daylight hours only to prevent disturbance to any otters that could be passing through. Furthermore, it is recommended that otter-proof fencing is used around all site compounds and storage areas, to prevent this species from accessing these areas.
5.2. Conclusions
There was no evidence of water vole or otter within the stretch of the Peak Forest Canal running adjacent to the proposed marina expansion site.
The habitats within the site were considered sub-optimal for use by water vole or otter.
The presence of these species at the site is therefore considered unlikely and it is considered unlikely that they will colonise the site in the future.
No negative impacts from the proposed works are therefore anticipated.

Peak Ecology Ltd Furness Vale Marina: Further Bat Survey
1. INTRODUCTION
This report has been prepared by Peak Ecology Ltd on behalf of Next Phase Development. It provides details of bat survey work undertaken on land adjacent to the existing Furness Vale Marina site in Furness Vale, High Peak (central grid reference: SK 007 836).
Peak Ecology Ltd carried out an Extended Phase 1 Habitat Survey at the site in July 2013, in relation to plans to expand the existing marina. This survey highlighted the potential of the site to be used by bats and further bat survey work was recommended.
The minimum level of survey work recommended was a transect survey in each of spring, summer and autumn, coupled with a minimum of five nights static monitoring during each of these seasons. This is in line with the standard good practice survey guidelines (Hundt, L 2012). This level of survey work is considered appropriate to gain information of the species of bats using the site at different times of year and the levels of bat activity across these periods. The aim of the survey reported here was;
x To gather information on the species of bats using the canal in autumn; x To gather information of the levels of bat activity across a five night period in autumn x To determine whether bats are using the habitats surrounding the canal and/or the water body itself
This level of information is considered sufficient to assess the potential impacts of the scheme on bats, as part of an Ecological Impact Assessment.
This report provides details of the autumn survey work. It is our understanding that spring and summer surveys will be undertaken, as recommended, in 2014.
All bat species are listed on Schedule 5 of the Wildlife and Countryside Act 1981 (as amended) and are protected by Parts 4(b), 4(c) and 5 of Section 9 of that Act. All bat species are also European Protected Species under the Conservation of Habitats and Species Regulations 2010.
In net effect, it is a legal offence to:
x Deliberately capture, injure or kill bats; x Intentionally or recklessly disturb bats; x Intentionally or recklessly damage, destroy or obscure access to a breeding site or resting place* x Possess, control, transport, sell or exchange a bat or any part of a bat, unless acquired legally.
*Because bats use roosts at different times of year, and often return to the same roosts annually; a bat roost is protected whether bats are in occupancy at the time or not.

2. METHODOLOGY
2.1. Autumn transect survey
A single transect survey was undertaken on 8th October 2013, during weather conditions considered suitable for bat activity. Further details are provided in Table 1 below.
Table 1: Transect details
Season: Autumn Date: 08/10/13
Weather at Start Temp: 140C Wind: 2-3 Precipitation: 0
Weather at End Temp: 130C Wind: 1 Precipitation: 0
N.B. Wind is measured using the Beaufort scale
The survey commenced at approximately sunset (18.29) and continued for 1.5hours after sunset. The methods used followed those within the survey guidelines, which state that surveys should be designed to ensure that all features identified that may be used by bats are sampled within 2-3 hours after sunset. The surveyors walked at a steady pace and incorporated all habitats at the site. Surveyors used a handheld AnaBat SD1 detector, linked to a BatNav GPS unit. Bat calls were recorded and the location where they were seen/heard and the corresponding time were marked on a site map. The calls were then analysed to determine the species, using AnaLookW (3.9c).
2.2. Static Monitoring
An AnaBat SD2 was left at the site between 08/10/13 and 15/10/13. The detector was located within a mature lime 7LOLD sp. tree towards the southern end of the survey area (see Figure 1). The detector was set to record from 30 minutes before sunset until dawn and the calls were subsequently analysed using AnaLookW (3.9c) software.
3. RESULTS
3.1. Transect Survey
The results of the transect survey are shown on Figure 1 overleaf.
A relatively low number of bat calls were recorded during this survey, although this may be expected due to the time of year. By October, many bat species have started preparing for winter and are swarming at potential mating and/or hibernation sites.
However, a variety of species were recorded, suggesting that a good assemblage of bat species is active in the vicinity. Common pipistrelle 3LSLVWUHOOXVSLSLVWUHOOXVand soprano pipistrelle 3LSLVWUHOOXV S\JPDHXVare amongst the UK’s commonest bat species and 0\RWLV and noctule 1\FWDOXVQRFWXOD
5
Peak Ecology Ltd Furness Vale Marina: Further Bat Survey bats are also relatively common in Derbyshire. It is difficult to distinguish between 0\RWLV bat species using only an analysis of their calls, particularly where the calls are faint or interspersed with other bat species. However, Daubenton’s bats 0\RWLV GDXEHQWRQLL are known for foraging along water bodies and we expect this species to be present in a canal side location. Species including natterer’s 0\RWLVQDWWHULL, brandt’s 0\RWLVEUDQGWLL and whiskered 0\RWLVP\VWDFLQXV bats could all also be present. The calls recorded were not characteristic of any species that would be classified as rare in this part of Derbyshire.
The open water and the tree cover, both along the canal tow path and along the application site’s south-western boundary, provided good potential foraging and commuting habitat and in the wider area, the River Goyt and associated vegetation offers optimal foraging habitat.
The first bat was recorded at 18.52. This is 23 minutes after sunset. Both pipistrelle and 0\RWLV bats can begin to emerge approximately 20minutes after sunset, suggesting that these bats are roosting nearby. The canal or tree lines may be used by these bats commuting from a roosting location to foraging grounds. However, bat activity continued at regular intervals for the duration of the survey, suggesting bats are also foraging at this location. Social calls were also recorded.

3.2. Static Monitoring
Due to the need for the detector to remain secure, the AnaBat static monitoring device was located within a tree. However, upon analysing the calls, it was difficult to differentiate between calls of different species and there were a large number of noise files, as well as noise mixed in with what appeared to be bat calls. It was considered likely that this represented the noise made by the tree, which was in leaf at the time of the survey. Many of the calls did not display the maximum and minimum frequency parameters we would usually associate with bat calls, therefore it was assumed that bat calls were those with a regular repetition, within the range usually associated with bat calls and the analysis was undertaken by analysing the peak frequency.
Table 2 shows the data recorded by the static monitoring device.

4. DISCUSSION & RECOMMENDATIONS
The survey results show that the site is used by a variety of common bat species. This reflects the good quality habitat that is currently present at the site, particularly the standing water, trees and shrubs. The static monitoring did not appear to show any regular patterns to bat activity at the site, suggesting it does not form part of an important commuting route at this time of year. It is considered likely that it is used by foraging bats. This would be expected, given the likely high volume of invertebrates (bat prey items) associated with the watercourse. We would expect to see a similar pattern of use at all times of year.
The expanded marina will result in the loss of an area of amenity grassland and semi-improved grassland, as well as some marginal vegetation and an increase in standing water (albeit, used for boat mooring). The majority of the mature trees and site boundaries will remain unaffected. Overall, the habitat change is considered to be neutral in relation to foraging bats; amenity grassland and semi-improved grassland are sub-optimal habitats for bat foraging activity, due to their open and exposed nature. Although an increase in standing water would appear to provide an increase in foraging potential at the site, as this will mostly be used by moored boats, the surface area available for foraging bats will be minimal.
As mentioned in Section 1, in order to comply with the current good practice guidance, additional surveys in spring and summer would be required. Whilst Peak Ecology recommend that this approach is followed, in order to provide a complete picture of bat activity at the site, it is considered extremely unlikely that additional survey work would change the predicted level of impact on bats and the recommended mitigation.
Opportunities to enhance the site for bats are available in the form of additional planting, particularly around the site’s perimeters. This should include mature trees and shrubs, comprising native species.
Low-level lighting is currently present around the water’s edge and around the marina buildings. The new marina will include some additional lighting but this will remain low level and only at the water’s edge. Lighting must not shine directly at any trees or shrubs and dark corridors should be maintained around the site’s perimeters.
9
Peak Ecology Ltd Furness Vale Marina: Further Bat Survey
The site is also relatively secure, being gated at night and therefore the installation of bat boxes on mature trees could also be considered to provide potential roosting sites for bats, as these were noted to be lacking at the site. Bat boxes should be situated in groups of three per tree, with each box having a different facing aspect. Boxes should be positioned over 2m in height to avoid any interference and should be sited away from branches or other features that could be used by waiting predators.
If additional planting is undertaken and the lighting plan is carefully considered, it is considered that the proposed marina expansion could result in an increase in the foraging and roosting potential for bats at this site.

Peak Ecology Ltd Furness Vale Marina: Terrestrial Invertebrate Survey
1. INTRODUCTION
In July 2013, Peak Ecology carried out an Extended Phase 1 habitat survey, on behalf of Next Phase Developments, on land adjacent to the existing Furness Vale marina. Within the Phase 1 report (Peak Ecology, 2013), a terrestrial invertebrate survey of a single grassy field adjacent to the Peak Forest Canal was recommended (see photograph, right). At the time of the Phase 1 survey, a high abundance of butterflies and day-flying moths (Lepidoptera) of multiple species, together with dragonflies (Odonata: Anisoptera), hoverflies (Diptera: Syrphidae) and bumblebees (Hymenoptera: Apidae), were present within this field.
2. METHODOLOGY
The site visit was visited by Dr Mark Webb, Director at Peak Ecology on the 17th October 2013. The weather conditions were 12 – 14°C, light cloud with mildly sunny intervals and a mild breeze, i.e. favourable for the time of year.
The site was thoroughly walked over in a zig-zag fashion, with attention paid to more promising areas for example any potential nectar sources in the form of fresh flowers or patches of sun. Any invertebrates seen were either identified by eye in flight or swept with a net for examination in the hand, with specimens retained for identification using a stereo binocular microscope as appropriate. At the same time, an evaluation of the potential of the site to support terrestrial invertebrates was implemented. Target groups included:
• Coleoptera (beetles): Coccinellidae (ladybirds), Cantharidae (soldier beetles), Carabidae (ground beetles) and others;
• Diptera (true flies): Syrphidae (hoverflies), larger Brachycera (solderflies and their allies) and others;
• Hemiptera (true bugs): Pentatomoidea (shield and squash bugs);
• Hymenoptera (bees, ants and wasps): Apidae (bumblebees) and Vespidae (social wasps);
• Lepidoptera (butterflies and moths),
• Odonata (dragonflies and damselflies), and;
• Orthoptera (grasshoppers and crickets).
Photographs from the site including habitats and key features have been included throughout the report.

3. RESULTS
3.1. Site Description
The study site for the terrestrial invertebrates site visit was a long rectangular grassy field, estimated to be between 200 and 300m long and 20m wide. The site was bordered along its southeastern long edge by the Peak Forest Canal and along its northwestern long edge by the Buxton to Manchester railway line (see photographs, below). This field represents the location of Phase 2 of the development.
The presence of a small, rundown livestock shelter and the overgrown state of the grassland suggest that it was used up until recently, but no longer, as a pasture field, perhaps for a pony or donkey. Again from the condition of the vegetation, it would appear that the site has been ungrazed or unmanaged for a period of no longer than 12 months.
0Presently, the field is composed of tall, grassy vegetation. Owing to being unmanaged, it is becoming increasingly coarse and thick with tall herb species such as hogweed Heracleum sphondylium, common nettle Urtica dioica, and creeping thistle Cirsium arvense (see photograph, right). There are significant stands of approximately 100 to 200m2 of each of these species.
At the northern end of the field, field conditions are wetter, and the coarse grass dominated vegetation gives way to significant areas dominated by rushes including soft rush Juncus effusus and compact rush J. conglomeratus.
Peak Ecology (2013) describes the field as follows:
A large field forming the northern half of the site was dominated by semi-improved grassland. This appeared to have been grazed in the past (due to the presence of a stable building). However, there were no signs of current management and the

sward had grown to approximately 1m high in places. There was a good mix of grassland species present including Yorkshire fog Holcus lanatus, meadow foxtail Alopecurus pratensis, false oat grass Arrhenatherum elatius, red fescue Festuca rubra, common couch Elymus repens, Timothy Phleum pratense, meadow grass (Poa spp.) and perennial rye grass Lolium perenne. Herb species were dominated by creeping thistle Cirsium arvense but there was also abundant meadow vetchling Lathyrus pratensis, black medick Medicago lupulina, tufted vetch Vicia cracca, red clover Trifolium pratense, white clover T. repens, curled dock Rumex crispus and meadow buttercup Ranunculus acris amongst others.
Later in the Phase 1 report, under the sub-heading of Terrestrial Invertebrates, the potential value to invertebrates is described as follows:
The longer sward grassland was noted to support a diverse assemblage of butterflies and day-flying moths with large white Pieris brassicae, cinnabar Tyria jacobaeae, meadow brown Maniola jurtina and red admiral Vanessa atalanta all recorded during the survey. A number of other invertebrates were also noted in this area.
Sites such as this often form part of a wider connected resource of suitable habitat used by common invertebrate species. However, on occasion, they can support species listed on the UK or Local BAP and cinnabar is a UK BAP Priority Species
3.2. Findings
Significantly, the survey took place during relatively favourable conditions following a very good summer and at that time there had been no autumn frosts. This is significant because the first autumn frosts often kill off a large number of late summer invertebrates, essentially curtailing the season.
However, virtually no invertebrate activity was evident on the day of survey. The only species recorded were comma butterfly Polygonia c-album, common carder bee Bombus pascuorum, silver Y moth Autographa gamma and harlequin ladybird Harmonia axyridis.
Species recorded during the Phase 1 survey included large white butterfly Pieris brassicae, cinnabar moth Tyria jacobaeae, meadow brown butterfly Maniola jurtina, and red admiral butterfly Vanessa atalanta.
All of these species are common and widespread species of tall grassland and tall ruderal habitats.
4. CONCLUSIONS
From an evaluation of the habitats and plant species present, and given the small number of species recorded, it would appear that this grassy field supports a fair abundance of common and widespread invertebrate species. The presence of abundant nectar, particularly from creeping
6
Peak Ecology Ltd Furness Vale Marina: Terrestrial Invertebrate Survey thistle and hogweed (see photograph, right), would attract good number of butterflies, hoverflies and bumblebees, for example. 2013 was an exceptionally good year for these groups, particularly butterflies, and this goes some way to explaining the high abundance witnessed by the ecologists carrying out the Phase 1 habitat survey in July. Also, plants present within the field would act as foodplants for various species, such as common nettles providing food for caterpillars of butterflies like small tortoiseshell Aglais urticae, comma, peacock Inachis io and red admiral.
The recently abandoned nature of the field strongly suggests that this high level of summer use by invertebrates is a recent phenomenon, probably happening for the first time in 2013 as the thistles and such like present grew up and flowered in the absence of grazing or browsing.
Overall, this field represents a common and widespread habitat type of no more than local value to invertebrates.

Description and Reasons for Notification:
This part of the Huddersfield Narrow Canal runs from its junction with the Peak Forest Canal, 0.75 km north-west of Dukinfield, eastward through industrial areas to Stalybridge then northwards through more open countryside to the Tollemache Arms lock, 1.5 km north of Mossley, where the A635 crosses the canal. It is underlain by Carboniferous Westphalian and Namurian Coal Measures, covered by glacial sands, gravels and boulder clays. The canal is divided into four sections of different character and rates of waterflow, by underground culverts or tunnels. The locks have been cascaded.
The canal is the best example of a flowing eutrophic water system in Greater Manchester, and the second best canal, differing from the mesotrophic Hollinwood Branch Canal SSSI, in being less acidic and faster flowing and in having a deeper profile which limits the extent of emergent species. The main habitats present are standing and running water, swamp, tall fen and fragmentary marginal vegetation. Unimproved and semi-improved neutral and acidic grassland, scattered shrubs and areas of bracken occur along the towpath and canal banks.
The open water communities are particularly diverse and prolific, a feature which may be attributed to the high water quality of the canal.
There is an exceptional range of pondweeds Potamogeton spp., including notably perfoliate pondweed, grass-wrack pondweed P. compressus, long-stalked pondweed P. praelongus, fennel pondweed P. pectinatus and hairlike pondweed P. trichoides. Canadian waterweed and Nuttall’s waterweed Elodea nuttallii, together with spiked water-milfoil Myriophyllum spicatum and common water-starwort form extensive beds, particularly in the deeper and faster flowing sections. Floating water-plantain Luronium natans, water violet Hottonia palustris, unbranched bur-reed, autumnal water-starwort Callitriche hermaphroditica and water fern Azolla filiculoides are locally abundant in some sections.
The diverse emergent vegetation of the canal includes stands dominated by any of reed sweet-grass, branched bur-reed Sparganium erectum, arrowhead Sagittaria sagittifolia, watercress, bulrush and flowering rush Butomus umbellatus.
These species also occur in a variety of combinations and degrees of dominance in different sections of the site, forming mixed fen vegetation on the immediate canal margins in which water forget-me-not, water plantain Alisma plantago-aquatica, great willow herb, remote sedge Carex remota, soft and jointed rush, common spiked-rush Eleocharis palustris, yellow iris and sweet flag Acorus calamus, amongst others, also occur.
The towpath bank of the canal bears mainly a neutral grassland in which common bent, Yorkshire fog and cock’s-foot are dominant, but acidic grassland dominated by wavy hair-grass occurs locally. A range of trees and shrubs have developed on certain sections of the bank.
The stonework of the canal bank has a distinct community which includes the largest population of the royal fern Osmunda regalis in the scheduling unit.
Several of the plants present are nationally rare including floating water-plantain, autumnal star-wort, grass-wrack pondweed, long-stalked pondweed and hairlike pondweed. In addition, a number are scarce within the scheduling unit notably small pondweed, fennel pondweed, water violet, water fern, sweet-flag, flowering rush and royal fern.
The aquatic fauna is also diverse with, for example, fourteen species of mollusc having been recorded and there is an exceptionally strong population of the fresh-water sponge Spongilla lacustris. UNITARY AUTHORITY: Oldham, Rochdale SITE NAME: Rochdale Canal

Reasons for Notification
The Rochdale Canal contains important habitats for submerged aquatic plants and emergent vegetation, including extensive colonies of the nationally scarce SAC species floating water- plantain Luronium natans.
The site also supports a diverse assemblage of aquatic flora, notably its assemblage of pondweeds, Potamogeton spp; the nine species of which found in the canal represent a balanced community which reflects the quality of water.
General Description
This partially restored section of the Rochdale Canal extends approximately 20 km from Littleborough to Failsworth, passing through urban and industrialised parts of Rochdale and Oldham and the intervening areas of agricultural land (mostly pasture).
Water supplied to the Rochdale Canal in part arises from the Pennines. This water is acidic and relatively low in nutrients, while water from other sources is mostly high in nutrients. The aquatic flora of the canal is thus indicative of a mesotrophic water quality (i.e. is moderately nutrient-rich) although there is evidence of some local enrichment.
One species strongly associated with mesotrophic conditions is floating water-plantain Luronium natans. The flora of the canal is very diverse, partly because mesotrophic water (which has a pH between 5.5 and 6.5, rarely up to 7) supports a continuum of species within a wide pH range. Thus there are species which tolerate acid to moderately acid water (pH 4.5- pH 6.0) and a different group of species tolerant of moderately acid to alkaline conditions (pH 6.0 to pH 9.0).
Two species found in the canal which occur in acidic waters are alternate-leaved water milfoil Myriophyllum alterniflorum and bottle sedge Carex rostrata. The pondweeds Potamogeton spp. are indicative of a wide range of nutrient conditions and pH tolerance. However some are only found in moderately acid to moderately alkaline conditions. These are red pondweed Potamogeton alpinus, various-leaved pondweed Potamogeton gramineus and blunt-leaved pondweed Potamogeton obtusifolius. Others are more generalist species, tolerant of a wide trophic or pH range. These are small pondweed Potamogeton berchtoldii, perfoliate pondweed Potamogeton perfoliatus, broad-leaved pondweed Potamogeton natans and curled pondweed Potamogeton crispus.
The canal contains significant stands in the Greater Manchester area of the emergent species water violet Hottonia palustris. Other emergent vegetation is dominated by extensive beds of reed sweet-grass Glyceria maxima with occasional stands of common reedmace Typha latifolia. Arrowhead Sagittaria sagittifolia, water-plantain Alisma plantago-aquatica and branched bur-reed Sparganium erectum, also occur frequently. Other marginal plants include yellow flag Iris pseudacorus, gipsywort Lycopus europaeus, cuckooflower Cardamine pratensis, water mint Mentha aquatica, marsh bedstraw Galium palustre, marsh woundwort Stachys palustris, and water forget-me-not Myosotis scorpioides. The bank-stones are sometimes colonised by ferns, notably lady fern Athyrium filix-femina and the locally uncommon royal fern Osmunda regalis. Found submerged on stones is the locally uncommon freshwater sponge Spongilla lacustris.
Canals, because of the history of boat movements, often contain species well outside their normal geographic range. The nationally scarce water soldier Stratiotes aloides and fringed water-lily Nymphoides peltata are naturally confined to East Anglia. Their presence in the Rochdale Canal is almost certainly due to barge traffic moving species from one part of the country to another. However the Rochdale Canal is also noted for its extensive populations of the nationally rare American pondweed Potamogeton epihydrus. This was probably introduced from North America in the 1850's when the mills used imported as well as local fibres.
There is a rich but generally common-place invertebrate assemblage in excess of 112 species; 13 of these species are of local importance. Two species are nationally scarce, a water beetle Agabus uliginosus (Notable B) and the Pea Mussel Pisidium pulchellum. This latter species is not known in any other Greater Manchester canal. Predatory macro-invertebrates such as caddis fly larvae, adult and larval water beetles, dragonfly and damselfly larvae and certain water bugs amongst a predominantly herbivore-detritivore community is indicative of a healthy structured ecosystem. Twelve species of coarse fish predate on these invertebrate species.
The canal also provides habitat for a number of waterside bird species. Coot, moorhen and mallard breed along the length of the canal, whilst grey wagtail also breeds in smaller numbers and kingfisher regularly use the canal for feeding.

4.3 Vulnerability This partially restored section of the Rochdale Canal extends approximately 20 km from Littleborough to Failsworth, passing through urban and industrialised parts of Rochdale and Oldham and the intervening areas of agricultural land (mostly pasture). The canal contains important habitats for submerged aquatic plants and emergent vegetation, including extensive colonies of Luronium natans. The canal is to be subject to a major restoration scheme to open it up for full navigation from Manchester to Yorkshire, including the SSSI / pSAC section. English Nature is working together with partners to ensure the restoration is sensitively done in order to preserve the interest of the site. However, there are concerns about future boat movements as the possible impacts are not fully known at this stage.

Appendix 5 – Conversion of Lock Count data to Boat
Movements
Application of Lockage Ratios:
Lockage ratios are used to convert estimates of boat movements into estimates of lockages, and vice versa.
CRT operates a boat traffic model which uses a computer programme, utilising data from log book surveys and boat counters, to assess the estimated impacts of any new marina (or other relevant canal developments) in terms of the likely movements/trips of boats based there and the locks they would use. The model generates estimates in terms of additional boat movements at any specified point on the network.
Where this data is used by the Water Management Team (WMT) to assess lockage impacts, the model generates figures at the affected locks and a ratio is applied by the WMT to convert boat movements to lockages. This is because the number of lockages dictates the water impact, rather than movements. A single lock of water may represent between 1 and 2 boat movements for a narrow lock, and between 1 and 4 boat movements for a wide lock. Therefore the WMT will use local knowledge to use the most suitable ratio for any specific lock (i.e. say 2.6 for busier wide locks).
Where lockage data (e.g. from the Annual Lockage Report) is converted to boat movements, the ratio is used in reverse. Where a general figure for wide locks is required this generally taken as 2.0 to average out the quieter and busier locks across the network. For a narrow lock the ratio is 1.4, ie on average 1.4 boat movements per lockage.
