It is recognised that effects on capercaillie at any one of the Badenoch and Strathspey capercaillie SPAs or associated woodlands shown on the map in Annex I has the potential to affect the wider capercaillie metapopulation of Badenoch and Strathspey. While other capercaillie SPAs are considered in this HRA, attention has been focused in this HRA on the capercaillie woods likely to be used regularly for recreation by users of the proposed development site, which in this case is Kinveachy Forest SPA (including Wood I‑Kinveachy Forest) (see Annex2– Detailed Capercaillie Assessment).
² Elements of the proposed development are also within 975m of the Kinveachy Forest SAC, which is designated for Caledonian forest and bog woodland. However, it is considered that there is no connectivity between these habitat qualifying interests of this SAC and the project site, and so this site has been scoped out of further consideration.
³ Elements of the proposed development are within 3.1 km of the Cairngorms SAC, which is designated for Alpine and subalpine heaths, High-altitude plant communities associated with areas of water seepage, Blanket bog, Bog woodland, Green shield-moss, Plants in crevices on base-rich rocks, Caledonian forest, Dry heaths, Tall herb communities, Juniper on heaths of calcareous grasslands, Otter, Acid peat-stained lakes and ponds, Wet heathland with cross-leaved heath, Clear-water lakes or lochs with aquatic vegetation and poor to moderate nutrient levels, Hard-water springs depositing lime, Dry grasslands and scrublands on chalk or limestone, Montane acid grasslands, Plants in crevices on acid rocks, Acidic scree, Species-rich grasslands with mat-grass in upland areas, Mountain willow scrub, and Very wet mires often identified by an unstable ‘quaking’ surface. However, it is considered that there is no connectivity between the habitat qualifying interests of this SAC and the project site, and so this site has been scoped out of further consideration.

APPRAISAL STAGE 1: What is the plan or project?
Relevant summary details of proposal (including location, timing, methods, etc) The Aviemore to Carrbridge Non-Motorised User Route (ACNMU) scheme intends to provide an NMU link between the two settlements of Aviemore and Carrbridge. The Proposed Scheme largely follows along the B9152, A95 and B9153 roads. The Proposed Scheme passes close to several European designated site for nature conservation. There is no programme for the works at present and the construction commencement date is currently not known.
STAGE 2: Is the plan or project directly connected with or necessary for the management of the European site for nature conservation?
1) Loch Vaa SPA No, this project is not directly connected with or necessary for the management of the European site for nature conservation.

3) Kinveachy Forest SPA No, this project is not directly connected with or necessary for the management of the European site for nature conservation.
4) Cairngorms SPA No, this project is not directly connected with or necessary for the management of the European site for nature conservation.
5) Abernethy Forest SPA No, this project is not directly connected with or necessary for the management of the European site for nature conservation.

7) Anagach Woods SPA No, this project is not directly connected with or necessary for the management of the European site for nature conservation.
page 7 of 34
STAGE 3: Is the plan or project (either alone or in-combination with other plans or projects) likely to have a significant effect on the site(s)?
1) Loch Vaa SPA (less than 50m from development)
Slavonian grebe (breeding): Yes, there will be an LSE, due to disturbance to breeding Slavonian grebe during construction phase, and operational phase, and as a result of potential impacts on habitat during construction. There will be similar impacts at Avielochan where breeding Slavonian Grebe have likely connectivity with the Loch Vaa SPA population.
2) River Spey SAC (within 750m)
Otter: Yes, there will be an LSE, due to habitat degradation during construction and potential disturbance during construction. Atlantic salmon: Yes, there will be an LSE, due to habitat degradation and disturbance to spawning during construction. Sea lamprey: Yes, there will be an LSE, due to habitat degradation during construction. Freshwater pearl mussel: Yes, there will be an LSE, due to habitat degradation during construction.
(The River Spey flows south to north, to the east of the proposed NMU route, with the River Dulnain, one of its tributaries flowing through Carrbridge to the north of the route. The River Spey SAC is approximately 730 m north and 920 m to the east of the proposed route at the closest points. The route crosses three tributaries of the River Spey: Feith Mhor at OSGR NH90992134, Easter Aviemore Burn at OSGR: NH39771428 and an unnamed small watercourse at OSGR NH89881459. Therefore, there is a hydrological connection between the route and the SAC)
3) Kinveachy Forest SPA (within 1km – however Kinveachy capercaillie wood I includes supporting habitat within 300m of the development)
Capercaillie (breeding): Yes, there will be an LSE. The capercaillie population within this SPA is part of the wider Strathspey metapopulation that has connectivity to the neighbouring capercaillie SPAs (Abernethy Forest SPA, Anagach Woods SPA, Cairngorms SPA, Craigmore Wood SPA and Kinveachy Forest SPA) and capercaillie woodlands (see Annex1). There will be a likely significant effect on this qualifying interest due to loss of supporting habitat, disturbance during the construction phase and the disturbance during the operational phase. Scottish crossbill: Yes, there will be an LSE. There is likely connectivity between the SPA and supporting non-designated woodland habitat close to and within the proposed development boundary. Due to disturbance during construction work, and potentially during operation.
4) Cairngorms SPA (approx. 3.1km)
Golden eagle: No LSE, the proposed development is approximately 3.1 km from the SPA and the habitats involved are not suitable for foraging or nesting Golden Eagle, and so this qualifying interest has been scoped out from further consideration. Dotterel: No LSE, the proposed development is approximately 3.1 km from the SPA and the habitats involved are not suitable for Dotterel, and so this qualifying interest has been scoped
page 8 of 34
out from further consideration. Merlin: No LSE, the proposed development is approximately 3.1 km from the SPA and the habitats impacted are not suitable for Merlin, and so this qualifying interest has been scoped out from further consideration. Peregrine: No LSE, the proposed development is approximately 3.1 km from the SPA, so no direct impact on habitat within the SPA, and this species has a large range which is unlikely to be impacted by this development, and so this qualifying interest has been scoped out from further consideration. Scottish crossbill: No, LSE. While the Scottish Crossbill population within this SPA is likely part of a wider metapopulation that has connectivity with Scottish Crossbill populations in neighbouring SPAs, it is considered that breeding crossbills within this site would not be dependent on foraging habitats more than 3.1 km from nest sites within this SPA. Osprey: Yes, there will be an LSE. Suitable foraging habitats (Loch Vaa and Avielochan) directly adjacent to the proposed development could be used by foraging Osprey from the Cairngorms SPA, and there may be short-term disturbance from construction activity. Capercaillie: Yes, there will be an LSE. The capercaillie population within this SPA is part of the wider Strathspey metapopulation that has connectivity to the neighbouring capercaillie SPAs (Abernethy Forest SPA, Anagach Woods SPA, Cairngorms SPA, Craigmore Wood SPA and Kinveachy Forest SPA) and capercaillie woodlands (see Annex1).
5) Abernethy Forest SPA (approx. 3.8km)
Scottish crossbill: No, LSE. While the Scottish Crossbill population within this SPA is likely part of a wider metapopulation that has connectivity with Scottish Crossbill populations in neighbouring SPAs, it is considered that breeding crossbills within this site would not be dependent on foraging habitats more than 3.8 km from nest sites within this SPA. Osprey: Yes, there will be an LSE. Suitable foraging habitats (Loch Vaa and Avielochan) directly adjacent to the proposed development could be used by foraging Osprey from the Abernethy Forest SPA, and there may be a short-term disturbance from construction activity. Capercaillie: Yes, there will be an LSE. The capercaillie population within this SPA is part of the wider Strathspey metapopulation that has connectivity to the neighbouring capercaillie SPAs (Abernethy Forest SPA, Anagach Woods SPA, Cairngorms SPA, Craigmore Wood SPA and Kinveachy Forest SPA) and capercaillie woodlands (see Annex1).
6) Craigmore Wood SPA (approx.10km)
Capercaillie (breeding): Yes, there will be an LSE. The capercaillie population within this SPA is part of the wider Strathspey metapopulation that has connectivity to the neighbouring capercaillie SPAs (Abernethy Forest SPA, Anagach Woods SPA, Cairngorms SPA, Craigmore Wood SPA and Kinveachy Forest SPA) and capercaillie woodlands (see Annex1).
page 9 of 34
7) Anagach Woods SPA (approx. 13.8km)
Capercaillie (breeding): Yes, there will be an LSE. The capercaillie population within this SPA is part of the wider Strathspey metapopulation that has connectivity to the neighbouring capercaillie SPAs (Abernethy Forest SPA, Anagach Woods SPA, Cairngorms SPA, Craigmore Wood SPA and Kinveachy Forest SPA) and capercaillie woodlands (see Annex1).
STAGE 4: Undertake an Appropriate Assessment of the implications for the site(s) in view of the(ir) conservation objectives
1) Loch Vaa SPA
To avoid deterioration of the habitats of the qualifying species: Slavonian Grebe (breeding) or significant disturbance to the qualifying species, thus ensuring that the integrity of the site is maintained; and To ensure for the qualifying species that the following are maintained in the long term: Distribution of the species within site.
In the UK most records of Slavonian grebes are of autumn/winter migrants, however approximately 28 pairs breed in the UK each year. Nests are normally built in reed beds, sedge beds or in the semi-submerged branches of willows around the edges of small lochs and other waterbodies. Up to seven pairs of Slavonian grebes breed at Loch Vaa each year, however numbers fluctuate, particularly in years with warm springs and/summers, which can result in low water levels and separation of open water in the deeper centre of the loch from emergent vegetation where the grebes nest around the outside (https://www.nature.scot/sites/default/files/site-special-scientific-interest/1065/site-management-statement.pdf).
There is connectivity between the population of Slavonian grebes breeding at Loch Vaa and those at Avie Lochan, and birds may move between both sites before settling down to breed. During the breeding season the distribution of the species within the site is dependent on the extent of nesting and foraging habitats, water quality and the presence and abundance of prey species. Slavonian grebes are sensitive to disturbance within 350m of their nests (Ref: Disturbance Distances in selected Scottish Bird Species – NatureScot Guidance | NatureScot). The most recent site condition monitoring (in 2007) of the Slavonian grebe feature at Loch Vaa SSSI found that it was in unfavourable condition.
Construction activity for the NMU route will be undertaken within 20m Loch Vaa SPA (~100m from edge of the actual loch), and therefore pollution from construction work could affect water quality within the loch and have an impact prey species or vegetation in the loch. There is also likely to be some increase in noise and visual disturbance as a result of the construction work on the NMU route, however this increase is likely to be negligible, as the construction work will be separated from the loch by the busy A95 road and will be at least partly screened by woodland. Loch Vaa is already well used by walkers, swimmers and paddle-boarders, particularly during the summer months, which coincides with the Slavonian Grebe breeding season. Current access to Loch Vaa for water-sport activities is most likely from the Laggantygowan Cemetery. During the operation phase there is likely to be an increase in access to the site from users of the NMU route. Measures are proposed in the Mitigation Schedule to mitigate construction phase and operational-
page 10 of 34
phase impacts on the Slavonian grebes of Loch Vaa SPA. The following relevant measures are proposed in the Mitigation Schedule:
- Pre-construction surveys will be undertaken to verify and, where required, update the baseline ecological conditions.
- An Ecological Management Plan (EMP) including a Habitat Management Plan (HMP) and Species Protection Plans (SPP) will be prepared for the Proposed Scheme. This will detail methods to be adopted pre-construction, during construction and post-construction, including elements such as habitat reinstatement and creation, species and habitat translocation, mitigation measures to safeguard protected species (including timing of works and exclusion zones) and monitoring requirements (Mitigation ACNMU-E3).
- An Ecological Clerk of Works (ECoW) will be appointed to ensure that the EMP, HMP and SSP are implemented and followed during pre-construction phases, during construction and post-construction. (Mitigation ACNMU-E6)
- Construction works will take account of sensitive ecological seasons (e.g. breeding seasons) and the potential impact that the type of construction work could have on any protected or priority habitat or species within that season (ACNMU-E7).
- To minimise impacts habitats and species, the working area will be kept to the minimum necessary for construction of the Proposed Scheme to reduce habitat loss and impacts to protected and priority species and plant and personnel will be constrained to a prescribed working corridor through the use of temporary barriers to minimise the damage to habitats and potential direct mortality and disturbance to animals located within and adjacent to the Proposed Scheme working corridor. Parking will also be restricted to designated areas. (mitigations ACNMU-E9, E10, E39, and E40)
- The use of construction lighting will be in accordance with BS5489‑1:2020 Code of Practice for the Design of Road Lighting and follow best available guidance on lighting with regards to protected species (e.g. Institute of Lighting Professionals (2018)). The construction lighting design will take account of the need to avoid illuminating sensitive wildlife habitats in locations such as adjacent to watercourses; along woodland edges; and, where there is known activity identified through pre-construction ecological surveys. Where this is not possible the Contractor will agree any exceptions with NatureScot (ACNMU-EII).
- Mitigation measures to avoid or reduce potential effects on surface waters will be employed, including Guidance for Pollution Prevention (GPPs) and Construction Industry Research and Information Association (CIRIA) guidance on the control of water pollution from construction sites will be adhered to for the duration of the construction phase, and appropriate drainage and runoff treatment (ACNMU-E14).
- No working or artificial lighting within 50m of watercourses/waterbodies will be undertaken during the hours of darkness, taken to be 30 minutes before sunset to 30 minutes after sunrise, unless specifically agreed with NatureScot. Should this be unavoidable, lighting must be positioned to minimise light spill onto watercourses/waterbodies and will be subject to ECoW approval. The ECoW will monitor relevant species activity upstream and downstream of the works and may stop site activities at any time should they consider that the works are having an impact on a protected species (ACNMU-E33).
- Stock fencing (a combination of post and rail, and post and wire) is to be installed along the length of the NMU route. The fencing will restrict access to sensitive and protected sites
page 11 of 34
such as Loch Vaa SPA from the development and thus will help reduce impacts of operational-phase recreational disturbance (Mitigation ACNMU-E40). If these measures are implemented, they should help to mitigate effects on the species to allow this Conservation Objective to be met.
Distribution and extent of habitats supporting the species. Breeding Slavonian grebes are dependent on water bodies containing abundant small fish and invertebrates which they feed on. They nest in emergent vegetation including reed beds and sedge beds around the edges of lochs. Loch Vaa and Avie Lochan do not have physical connectivity, but there is exchange of Slavonian grebes between these sites before they settle down to nest, therefore impacts from this development on the distribution and extent of supporting habitats at Avie Lochan should also be considered (Ref: Advice from Alison Philip, RSPB Scotland Conservation Officer- South Highland). While there will be no construction work within Loch Vaa SPA or within Avie Lochan, and therefore no loss of habitats within either site, there may be impacts on water quality, habitats and prey species from construction activity. Loch Vaa and it’s surroundings are currently used for a variety of recreational activities including swimming, paddle boarding and walking. It’s possible that this development can increase levels of recreational activity in the vicinity of Loch Vaa and Avie Lochan, which could result in negative impacts on emergent vegetation and as well as increased disturbance in the operational phase, and therefore measures are required to mitigate these potential impacts on habitats. Measures discussed above, and detailed in the Mitigation Schedule to mitigate the impacts of this development on the distribution and extent of habitats supporting Slavonian grebes include Measures ACNMU-E3, E6, E9, E10, E14, E33 and E40. If these measures are implemented, they should help to mitigate effects on this species to allow this Conservation Objective to be met.
Structure, function and supporting processes of habitats supporting the species. As discussed above Slavonian grebes at Loch Vaa SPA (and Avie Lochan) are dependent on sensitive aquatic habitats. The impacts of pollution from construction phase activity on water quality, vegetation structure and composition (via toxins or increased nutrients), and the availability and abundance of prey species (small fish and invertebrates) within both Loch Vaa and Avie Lochan could have a detrimental impact on the structure, function and supporting processes of habitats that support Slavonian grebes. Therefore, measures are required to mitigate impacts on the breeding Slavonian grebes during the construction phase and post-construction phases of this development. If these measures are implemented, they should help to mitigate effects on the species to allow this Conservation Objective to be met.
No significant disturbance of the species. Without mitigation there is a potential for disturbance from both construction-phase activity and operational- phase recreational disturbance during the Slavonian grebe breeding season (April to end of August). Breeding Slavonian grebes are sensitive to disturbance within 350m of their nests. There is likely to some increase in noise and visual disturbance as a result of the construction work on the NMU route, however the impact of this disturbance is likely to be fairly minor/negligible, as the construction work will be separated from the loch by the busy A95 road and will be at least partly screened by woodland at the western edge of Loch Vaa SPA. Timing of works to avoid
page 12 of 34
construction activity during the breeding season would reduce the potential risk of construction-phase disturbance. Loch Vaa is well used by walkers, swimmers and watersports enthusiasts, particularly during the summer months, which coincides with the Slavonian grebe breeding season. Current access to Loch Vaa for water-sport activities is most likely from the carpark at the Laggantygowan Cemetery. An increase in access to Loch Vaa SPA from users of the NMU route is likely during the operational phase of the development, and therefore measures are required to mitigate disturbance impacts. Measures discussed above, and detailed in the Mitigation Schedule to mitigate the impacts of this development on the distribution and extent of habitats supporting Slavonian grebes include Measures ACNMU-EI, E3, E6, E7 and E40. Note that in addition to the use of stock fencing to restrict access to sensitive sites, it is proposed that no benches or seats will be installed close to sensitive sites to discourage people from stopping and then going exploring in surrounding habitats. If these measures are implemented, they should help to mitigate the potential effects of disturbance on this species to allow this Conservation Objective to be met.
Population of the species as a viable component of the site. As the other conservation objectives can be met for these species with the mitigation included in the proposal, the proposed development would not hinder or prevent the maintenance of the population of these species as a viable component of site.
In conclusion, the mitigation measures proposed in the application and discussed above reduces the potential effects to a minimal level, so that all the conservation objectives can be met for the Loch Vaa SPA.
2) River Spey SAC
Conservation Objective 2. To ensure that the integrity of the River Spey SAC is restored by meeting objectives 2a, 2b, 2c for each qualifying feature (and 2d for freshwater pearl mussel):
Atlantic Salmon and Freshwater Pearl Mussel.
2b. Restore the distribution of Atlantic salmon and freshwater pearl mussel throughout the site The current and potential distribution of Atlantic Salmon and FWPM within the site would not be directly affected as no development will occur in the River Spey SAC. However, the route will cross at least 3 tributaries of the River Spey which will require works including the extension of culverts, and temporary crossings and temporary watercourse diversions. Therefore pollution from construction activities (e.g. mobilised sediment, fuels or oils) could indirectly cause the distribution to change of Atlantic Salmon and FWPM within the River Spey SAC due to temporary changes in water quality, and, if significant amounts of sediment reach the watercourse, through smothering habitats supporting FWPM, or which are used by Atlantic salmon for spawning. Surveys for fish and FWPM within 5 watercourses along the route did not detect any Atlantic Salmon or FWPM, and habitats were unsuitable for FWPM. However, two watercourses including the Feith Mhor
page 13 of 34
tributary of the River Spey were considered to have stretches of habitat suitable for salmon parr. While no Atlantic Salmon or FWPM were detected in the watercourses that were surveyed, there is a potential for pollution to extend further downstream into areas that do support Atlantic salmon and FWPM.
The Mitigation Schedule outlines a number of measures (EI, E2, E3, E7, E9, E10, E11, E13, E33) that should, if conditioned and properly implemented reduce the risks of pollution impacting these species. These include:
- Preparation of a Construction Environment Management Plan (CEMP) containing a Habitat Management Plan (HMP) and Species Protection Plan (SPP) detailing methods to be adopted pre-construction, during construction and post-construction to safeguard protected species and habitats and monitoring requirements.
- All culverts and watercourse crossings will be sensitively designed and constructed with reference to SEPA’s good practice guides including: Engineering in the Water Environment Good Practice Guide: Bank Protection Rivers and Lochs; • Engineering in the Water Environment: Good Practice Guide — River Crossing; and Position Statement WAT-PS-06 – 02 — Culverting of Watercourses – Position Statement and Supporting Guidance.
- Restriction on the footprint of construction work to the minimum possible to reduce impacts on habitats and species, and where practicable, plant and personnel will be constrained within a working corridor to minimise damage to habitats and potential direct mortality or disturbance to species within of adjacent to the proposed scheme.
- Measures to reduce impacts of sediment or pollution on watercourses including adhering to the Guidance for Pollution Prevention (GPP) documents (Guidance for Pollution Prevention (GPP) documents | NetRegs | Environmental guidance for your business in Northern Ireland & Scotland) and the Construction Industry Research and Information Association (CIRIA) guidance on the control of water pollution from construction sites in the SUDS Manual: https://www.ciria.org/CIRIA/Memberships/The_SuDS_Manual_C753_Chapters.aspx. These should be detailed in a site-specific Pollution Prevention Plan.
If the measures proposed in the mitigation schedule are conditioned and implemented — this conservation objective would be met.
2c. Restore the habitats supporting Atlantic Salmon and freshwater pearl mussel within the site and availability of food. The current and potential restoration of the distribution of habitats supporting Atlantic salmon and FWPM within the site would not be directly affected as no development will occur in the watercourse. However, pollution from construction activities would affect supporting habitats if significant amounts of sediment reach the watercourse and cause smothering, reducing the distribution and extent of habitat suitable for spawning and juvenile salmon and habitats suitable for supporting FWPM (long term). However, mitigation measures for 2b above would reduce the risk of pollution reaching the
page 14 of 34
watercourse to a minimal level and so this conservation objective would be met.
2d. Restore the distribution and viability of freshwater pearl mussel host species and their supporting habitats. The distribution and viability of FWPM host species (Atlantic salmon & sea trout) would not be directly affected as no development will occur within the watercourse. However as discussed in 2b and 2c, there is potential for pollution from construction activities to indirectly affect the habitats supporting these species which may in turn lead to a change in distribution or in change in health of these host species. With the implementation of the mitigation measures discussed in 2b the risk of pollution events will be reduced therefore the development would not hinder the distribution or vitality of the host species, and so this conservation objective would be met.
2a. Restore the population of Atlantic Salmon (including range of genetic types) and freshwater pearl mussel as a viable component of the site. As the other conservation objectives can be met for Atlantic salmon and FWPM with mitigation, the proposed development would not hinder or prevent the restoration of the population of Atlantic salmon or FWPM as a viable component of site. However, the proposed works will not influence the range of genetic types of Atlantic Salmon within the SAC. Therefore, this conservation objective would be partially met.
Sea Lamprey
2b. Maintain the distribution of sea lamprey throughout the site. The current distribution of sea lamprey would not be directly impacted by the proposed development as no works will take place within the River Spey SAC. However, there is potential for pollution from construction activities which could indirectly impact upon spawning substrates (long term) and water quality (temporary) which may alter the distribution of sea lamprey. As detailed within 2b for Atlantic salmon & freshwater pearl mussel. A CEMP containing a mitigation measures including a Pollution Prevention Plan detailing good practice construction activity will reduce the risk of accidental pollution and therefore this conservation objective would be met.
2c. Maintain the habitats supporting sea lamprey within the site and availability of food. The current suitable habitats for supporting sea lamprey will not be directly impacted upon as no works will take place within the watercourse. However, there is potential for pollution, such as sediment to enter the watercourse and smoother the suitable spawning grounds (long term) making it difficult for the sea lamprey to find suitable habitat. Changes to water quality through suspended solids or chemicals (temporary) may lead to a reduction in food availability through negatively impacting the distribution of fish species. The implementation of pollution prevention measures will reduce the risk of pollution entering the watercourse therefore this conservation objective would be met.
2a. Maintain the population of sea lamprey as a viable component of the site.
page 15 of 34
As the other conservation objectives for sea lamprey can be met through the implementation of mitigation, the proposed development would not negatively impact on the current population of sea lamprey within the SAC, therefore this conservation objective would be met.
Otter
2b. Maintain the distribution of otter throughout the site. Otters can have very large home ranges of around 32km for males and 20km for females (Otter | NatureScot), and therefore may forage considerable distances along tributaries of the River Spey SAC, including the Feith Mhor, where an otter spraint was recorded during survey work for the development. No construction work is proposed within the Rive Spey SAC however the route will cross at least 3 non-designated, but connected tributaries, which will require works including the extension of culverts, and temporary crossings and temporary watercourse diversions. Therefore, disturbance from construction activity (noise, light or vibration) could lead to a change in otter distribution and foraging behaviour along these tributaries. Pollution from construction activities (e.g. mobilised sediment, fuels or oils) could impact the distribution of otter through impacts on habitat quality, prey species, or direct mortality through the bioaccumulation of toxins through prey items that had been exposed to pollution.
If measures proposed in the mitigation schedule are conditioned and implemented, this conservation objective would be met. These measures include:
- Undertaking pre-construction surveys to confirm and update existing biological baseline data; and where required obtaining and complying with requirements of any protected species mitigation licences, in respect of the works.
- Preparation of a Construction Environment Management Plan (CEMP) containing a Habitat Management Plan (HMP) and Species Protection Plan (SPP) detailing methods to be adopted pre-construction, during construction and post-construction to safeguard protected species and habitats and monitoring requirements.
- All culverts and watercourse crossings will be sensitively designed and constructed with reference to SEPA’s good practice guides including: Engineering in the Water Environment Good Practice Guide: Bank Protection Rivers and Lochs; • Engineering in the Water Environment: Good Practice Guide — River Crossing; and Position Statement WAT-PS-06 – 02 — Culverting of Watercourses – Position Statement and Supporting Guidance.
- Restriction on the footprint of construction work to the minimum possible to reduce impacts on habitats and species, and where practicable, plant and personnel will be constrained within a working corridor to minimise damage to habitats and potential direct mortality or disturbance to species within of adjacent to the proposed scheme.
- Restricting the programming of works to take account of ecologically sensitive time periods including breeding bird season (March-August inclusive).
