22/02715/PNO additional machine ramp supporting information: Note all illustrations are indicative and not-to-scale.
New machine ramp at NH867119 uses an existing ATV route, this will be widened and realigned with a new scrape for direct access (first photo below) and a new cross-ditch/dip installed across the existing ATV track to ensure surface runoff is pitched away from the track so it will not connect to a ditch which then connects to the nearby watercourse. The new cross drain (shown in the second photo below) will still be passable to ATVs.
Above: route of machine access, note purple mound shown above relates to the photo below. Below: existing low point in track needs to be enhanced and deepened, with materials used to build a downslope rise in the track ensuring water cannot pass down the track but is forced off the track at this point, it must still be passbale by an ATV. 1
NH867119 Existing junction to be wider New ramp 2 New cross drain
New machine ramp at NH867117 shown below, slightly shifted to the downslope side of the existing ditch line culvert, this will have a very marginal amount of fill (shown in yellow, no drainage culvert needed) and cut (shown in red) as shown below. This is just to get the machine up off the track and onto the hill. Expected usage will be minimal and we can consider re-vegetating it after use since its in a sensitive visual area.

KINRARA ESTATE: PROPOSED NEW WOODLAND PLANTING ECOLOGY SURVEYS INTRODUCTION SCOPE OF WORKS Blairbeg Consulting Ltd have been commissioned to carry out a suite of ecological surveys in summer 2021 on behalf of Scottish Woodlands Ltd for proposed new woodland planting at Kinrara Estate, near Aviemore in Highland. The objectives of the survey are as follows: • To provide base-line information on the location, extent and floristics of the existing vegetation, and presence and status of protected species within the site as delineated by the extent of the estate open ground (the ‘site’); • To produce an annotated vegetation map using the Phase 1 classification to identify and map the habitats. This is supported by habitat descriptions and target notes; To provide information on the location of sensitive ornithological interest within the site; To evaluate the status and nature conservation value of all sensitive ecological receptors and identify potential impacts resulting from new woodland expansion; and Recommend measures to mitigate any potential impacts of significance. SITE CHARACTERISTICS The site is located near Aviemore, lying west of the A9 public road and extending across a range of hills south of Kinveachy forest towards the River Dulnain. Beyond to the east, the site extends to headwaters of a number of tributaries of the River Dullnain bounded by Carn Dubh ‘Ic an Deoir south to Carn Caol. The site lies within the Cairngorm National Park Authority boundary.
The site rises from approximately 250m above sea level in the southeast to a high point of approximately 800m on the north-east flank of Geal-charn Mor. The site falls to the north-west of this to approximately 400m above sea level along the River Dulnain valley before rising to the range of hills at the western boundary which reach just over 700m above sea level. Much of the site lies higher than 500m above sea level.
All areas of the site are historically managed as grouse moor, with evidence of recent muirburn across the site. Whilst the grouse moor areas are grazed by livestock (sheep) at low-intensity, only the far south-east of the site near Lynwilg and some extensive field systems along the River Dulnain contains any currently active agricultural land management with a network of pasture fields. There are a number of small woodland areas along riparian areas, particularly along the Allt Dubh to the south-east and the River Dulnain but wooded areas are generally scarce. Patchy stands of coniferous woodland are present, particularly on Cnoc Beag, but evidence of regeneration is limited. Several small exclosures for woodland regeneration and planting exist above the mature treeline on the steeper eastern slopes of Creag Ghleannain and Creag na h‑lolaire. There are a number of bothies, stalkers huts and ruins within the site. 1| Page

TERRESTRIAL ECOLOGY SURVEYS METHODOLOGY BACKGROUND SURVEY Baseline data on the nature conservation interest of the site and its surroundings, including information on protected species and habitats records were sought from the following sources:
Joint Nature Conservation Committee (JNCC) website (http://www.jncc.gov.uk/); SNH Site Link website (http://gateway.snh.gov.ukl); and Large-scale 1:10,000 Ordnance Survey (OS) maps in conjunction with colour 1:25,000 OS map (to determine the presence of ponds and other features of nature conservation interest).
Further information relevant to evaluation of the nature conservation features that could be affected by the development and the assessment of its effects upon them was obtained through searches of internet sources (e.g. UKBAPs, LBAPs) and the relevant published literature (i.e. relevant guidance documents and scientific papers). PROTECTED SPECIES SURVEY MAMMALS Protected species surveys were undertaken in summer 2021, and followed the methodologies described below. An evaluation of the mammal species present on this site is provided in the results below. OTTER Otter field signs that were searched for, as described in Bang & Dahlstrøm (2001) and Sargent & Morris (2003), and include:
Holts — these are underground features where otters live. They can be tunnels within bank sides, underneath root plates or boulder piles, and even man-made structures such as disused drains. Holts are used by otters to rest up during the day, and are the usual site of natal or breeding sites. Otters may use holts permanently or temporarily; Couches — these are above ground resting-up sites. They may be partially sheltered, or fully exposed. Couches may be regularly used, especially in reed beds and on in-stream islands. They have been known to be used as natal and breeding sites. Couches can be very difficult to identify, and may consist of an area of flattened grass or earth. Where rocks or rock armour are used as couches, these can be almost impossible to identify without observing the otter in situ; Prints — otters have characteristic footprints that can be found in soft ground and muddy areas; 3| Page
Spraints — otter faeces are often used to mark territories, usually deposited on in-stream boulders. They can be present within or outside the entrances of holts and couches. Spraints have a characteristic smell and often contain fish remains; Feeding signs – the remains of prey items may be found at preferred feeding stations. Remains of fish, crabs or skinned amphibians can indicate the presence of otter; Paths — these are terrestrial routes that otters take when moving between resting-up sites and watercourses, or during high flow conditions when they will travel along bank sides in preference to swimming; and Slides and play areas – slides are typically worn areas on steep slopes where otters slide on their bellies, often found between holts/couches and watercourses. Play areas are used by juvenile otters in play, and are often evident by trampled vegetation and the presence of slides. These are often positioned in sheltered areas adjacent to the natal holt.
Any of the above signs are diagnostic evidence of the presence of otter; however, it is often not possible to identify couches with confidence unless other field signs are also present. Spraint is the most reliable identifiable evidence of the presence of this species.
Any evidence of otter presence was recorded onto 1:10,000 scale survey maps in the field. The location of all signs was also recorded via the use of a handheld GPS. SCOTTISH WILDCAT Field signs of wildcat are described in Davis & Gray (2010) and SNH (2011). Field evidence searched for includes:
Dens — can be found in hollow trees, rock crevices, rabbit burrows, disused fox dens and badger setts and under fallen debris; Prints — are distinctive cat prints, with no claw marks visible and a small palm pad with two indentations at rear; Scat — is usually cylindrical with a tapered end and contains feathers, fur and bone; Scratching posts on trees and fence posts; and Sightings.
Any of the above can be taken as diagnostic evidence that the presence of cats in the area. However, further surveys are required in order to identify if the cats present are wildcat or are a hybridisation with domestic cats i.e. feral cats.
If signs were found then further field survey methods would be required in order to establish if a den is present and if it is active. This can take several days/weeks depending upon the potential numbers of cats and habitat suitability. In areas where there are signs of wildcats camera traps can be used to try and verify presence and also to prove if a wildcat/hybrid or feral cat is present based on pelage characters. This would be the third step in the survey process if required (following the initial site assessment).
The key criteria for identifying Scottish wildcat are complex due to their ability to interbreed with domestic and feral cats. Scottish wildcat features and recognition are summarised in research by Kitchener et al., 2005 with clear methods for identification based on pelage (coat characteristics) 4| Page
from the study of dead cats. However with live cats in the field this is more problematic due to the difficulty in observing cats. In addition it is believed from field research that true wildcats are now very rare in the field with very low populations in many areas with much larger feral populations now present. Detailed field research is still required to accurately determine wildcat densities in many areas.
Any evidence of Scottish wildcat presence was recorded onto 1:10,000 scale survey maps in the field. The location of all signs was also recorded via the use of a handheld GPS. BADGER Badger field signs that were searched for, as described in Neal & Cheeseman (1996), Bang & Dahlstrøm (2001) and SNH (2002), included:
Setts are places of shelter often located in woodland, at woodland edges, in hedgerows or amongst dense patches of gorse and scrub close to fields; Prints — tracks lead from setts to latrines and foraging areas and prints are identifiable from broad palm-pad and five toe pads with claw marks in a row; Latrines (and dung pits used as territorial markers) – are where badgers deposit faeces in small excavated pits, and are often located at territory edges or close to a main sett; Hairs are often left in barbed wire or fencing as badgers pass through or underneath and are distinctive for their oval shape when rolled between finger and thumb; and Feeding signs (snuffle holes) — where badgers have dug up roots, grubs, or wasps nests and can be found throughout their territory.
Any of the above signs can be taken as diagnostic evidence of the presence of badger. Any evidence of badger presence was recorded onto 1:10,000 scale survey maps in the field. The location of all signs was also recorded via the use of a handheld GPS and photographs taken to visually catalogue the record. WATER VOLE The methodology prescribed in Dean et al. (2016) was followed in order to search for field signs of water vole. The field signs searched for included:
Faeces — recognisable by their size, shape, and content. If not too dried-out these are also distinguishable from rat droppings by their smell; Latrines — faeces, often deposited at discrete locations known as latrines; Feeding stations – food items are often brought to feeding stations along pathways and hauled onto platforms. Recognisable as neat piles of chewed vegetation up to 10cm long; Burrows — appear as a series of holes along the water’s edge distinguishable from rat burrows by size and position; Lawns — may appear as grazed areas around land holes; Nests — where the water table is high. Above ground woven nests may be found; Footprints — tracks may occur at the water’s edge and lead into bank side vegetation. May be distinguishable from rat footprints by size; and 5 | Page
Runways in vegetation – low tunnels pushed through vegetation near the water’s edge, less obvious than rat runs. Any of the above signs can be taken as diagnostic evidence of the presence of water vole. Any evidence of water vole presence was recorded onto 1:10,000 scale survey maps in the field. The location of all signs was also recorded via the use of a handheld GPS. RED SQUIRREL Through areas of woodland any sightings of red squirrel, signs of feeding and evidence of active dreys were recorded:
Dreys — are comprised of an outer shell of twigs and branches, with an inner layer of mosses, leaves, grass and conifer needles. Dreys are usually built close to the main stem of a tree; Feeding signs — can be stripped and nibbled conifer cones, split hazelnuts, nibbled fungus and berries.
Any evidence of red squirrel presence was recorded onto 1:10,000 scale survey maps in the field. The location of all signs was also recorded via the use of a handheld GPS. PINE MARTEN The field signs searched for included:
Scats — These are typically dark in colour and 4 – 12cm long x 0.8 – 1.8cm in diameter. They often have a coiled twisted appearance, typical of many mustelid scats. Scats will often contain food remains including fur, feathers, bone, plant content and seeds. Scats vary tremendously in size, shape and colour, and it’s difficult even for experts to identify some pine marten scats. Scats are placed in latrines at well-used dens (e.g. on lids of den boxes), as well as at sites elsewhere in an individual’s home range, where they probably fulfil a social communication role. Given the difficulty in confirming pine marten scat, any suspected scat will be sent for genetic analysis to conclusively distinguish it from other species. Footprints — The five-toed but slightly cat-like forefoot imprints measure approximately 40 x 45mm for females and 55 x 65mm for males; fur on the underside of feet in winter may blur prints and make them look larger, especially in soft snow, but pine martens have less fur on their feet pads than stone martens (present in continental Europe). Indistinct trails of bounding martens (stride length 60 – 100cm) may resemble those of hares, with prints in groups of two or three where one or both hind feet have registered over prints of forefeet. Den sites — Dens are usually not distinctive unless revealed by visible concentration of scats. Elevated den sites are preferred to keep martens safe from predators and provide insulation and shelter from the elements, and so hollow trees, owl boxes and the roofs of dwelling houses are often used, as well as purpose-built pine marten den boxes. Where such elevated dens are absent, they may den on the ground in rabbit burrows, rocky outcrops or under tree roof plates.
Any evidence of pine marten presence was recorded onto 1:10,000 scale survey maps in the field. The location of all signs was also recorded via the use of a handheld GPS. 6|Page
HABITAT SURVEY The vegetation was described and mapped following the methods described in National Vegetation Classification user’s handbook (Rodwell, 2006) and the Joint Nature Conservation Committee (JNCC) Handbook for Phase 1 Habitat Surveys (JNCC, 2010). Plant species were identified and habitat types assigned and mapped in the field. Mapping polygons were delineated based on the composition of habitats. Full data for each polygon is provided in Appendix 2: Habitat data. Polygons were laterally assigned a Phase 1 Habitat Classification, according to the relationships described in Phase One Habitat Classification (JNCC 2010). For the purposes of creating a visual representation of habitat types, the dominant Phase One Habitat Classification for each polygon is reflected. Phase 1 habitat maps were digitised using the ArcView 10.1 GIS package, with figures provided in Appendix 1, Figure 1: Habitat Survey Results.
More widely, target notes were also collected to provide an overview of the habitat types present, features of interest and to place the proposed development in the context of site. All target notes are accompanied by at least one photograph and provided in Appendix 3: Target notes.
Nomenclature for vascular plants follows Stace (2010), bryophytes and liverworts follow Atherton et al (2010) and for lichens Dobson (2011). A full species list for higher plants identified within the site is provided in Appendix 4: Species List. 7| Page
BASELINE CONDITIONS :PROTECTED SPECIES DESK STUDY Through the course of desk studies, reference was provided (pers. comm, Scottish Woodlands) to the presence of water vole in the catchment of the Allt Fionnaich. No detailed information was provided, however specific surveys for water vole in this area were undertaken. FIELD SURVEY Water vole burrows and latrines were recorded sporadically along two tributaries of the Allt Flonnaich. Along one tributary lying to the east of the access track (WV1: Start NH82363 1588, End NH8330 1552), a minimum of 14 burrows were recorded, in several patches amongst grasses and rushes along the watercourse banks. On a smaller tributary to the south-west of the access track (WV2: Start NH8234 1572, End NH 8228 1559), four burrows were recorded. At both locations evidence of recent use was indicated by active latrines and clipped vegetation at burrow entrances. Specific locations for burrows are not recorded here, but the extent of each colony is highlighted on Figure 6, Appendix 1.
No signs of other protected species were recorded within the site during the course of ecology surveys. Although not protected species, Rabbit, Mountain hare were observed within the site and signs of Fox were also recorded. LEGISLATIVE BACKGROUND Water vole (Arvicola amphibius) receive legal protection through inclusion on Schedule 5 of the Wildlife & Countryside Act 1981 (as amended), in respect of Section 9(4) only. This means that the water vole’s places of shelter are protected, but not the animals themselves. The Nature Conservation (Scotland) Act 2004 enhances this protection by inclusion of the term ‘recklessly’ in the offences quoted below. It is an offence to intentionally or recklessly:
Damage, destroy or obstruct access to any structure or place which water voles use for shelter of protection; and Disturb water voles while they are using such a place.
Water vole can be found along waterway edges in a variety of habitats from upland streams to wide rivers and agricultural ditches. They favour riparian habitats affording bank-side vegetation including grasses and sedges to provide food and cover from predators. They may tolerate brackish water and feed on halophytic plants, but do not generally inhabit areas that dry out twice daily, and so are largely absent from estuaries and salt marshes.
Water voles can create an extensive system of burrows with interconnecting tunnels and entrances both above and below the water surface. Steep banks with a slope angle of 35 degrees or more allow burrowing and importantly provide refuge during flooding events. However, vertical or overhanging 8| Page
banks may be difficult for water voles to access for burrowing, unless there are access ledges at water level. Rocky banks are generally avoided due to the difficulty of excavation.
Habitat loss and degradation, fluctuations in water levels and pollution have contributed to the water vole’s population decline in the UK, which has been greatly exacerbated by the spread of the American mink (Neovison vison), an introduced and efficient generalist predator. 9 Page
HABITAT Results from habitat surveys are mapped on Figure 1, Appendix 1. Results are provided in Appendix 2: Habitat data. Assigned GWDTE categories are displayed on Figure 2, Appendix 1. Target notes are provided in Appendix 3, and locations displayed on Figure 3, Appendix 1. A species list is provided in Appendix 4.
The majority of higher ground on the site consists of expanses of blanket mire communities. These are generally dominated by M17 Trichophorum germanicum-Eriophorum vaginatum blanket mire and M19 Calluna vulgaris-Eriophorum vaginatum blanket mire. Mires are subject to historic land drainage across most of their extent. At higher elevations and on exposed ridges and knolls evidence of erosion is apparent, with sometimes extensive areas of gullying and/or bare peat.
Steeper ground and areas of shallower soil are dominated by a mixture of dry and wet dwarf shrub heaths, varying with groundwater movement and substrate dryness. H10 Calluna vulgaris-Erica cinerea, H12 Calluna vulgaris-Vaccinium myrtillus and H16 Calluna vulgaris-Arctostaphylos uva-ursi dry heaths form the bulk of these habitats. The highest elevations and exposed summits are dominated by montane dry heaths and lichen heaths typically represented by H10 and H13 Calluna vulgaris-Cladonia portentosa heaths. Large areas of these dwarf shrub heaths, particularly in the east of the site, have been burnt for grouse moor management purposes, with consequent impacts on the habitat state and NVC classifications.
Gullies and riparian zones are occupied by sedge and rush-dominated acid flush communities, and are frequent and sometimes extensive along narrow drainage lines from higher to lower ground.
Gentle slopes and flatter areas along the River Dulnain and the south-eastern boundary of the site are affected by agricultural improvement, and a network of active and abandoned field systems are dominated by acidic and neutral grassland pasture, with wetter areas transitioning to marshy grasslands.
Woodland communities are semi-natural in nature, with fragments of Birch (Betula sp.) woodland particularly along the Allt Dubh. Stands of scattered of Scot’s pine (Pinus sylvestris) woodland are evident with denser stands on Cnoc Beag.
Other habitat types recorded were fragmentary or highly restricted in nature but include bog pools, sedge-mires, calcareous grasslands, marshy grasslands, Willow scrub and Bracken. 10 | Page

HABITAT AND COMMUNITY DESCRIPTIONS WOODLANDS AND SCRUB There are a number of areas of woodland present within the site boundary. However, established woodlands are generally limited. Fragments are associated with riparian corridors, being located along the Allt na Criche, Dulnain river and tributaries. and dominated by fragments of broadleaved Birch woodlands. Most other woodland areas are derived from regenerating Scot’s pine Pinus sylvestris woodland across knolls and ridges throughout the site. These stands differ in density and age structure, with the most concentrated areas on the north-east flank of Cnoc Bheag, towards larger areas of woodland along the Dulnain river. Stands of Scot’s pine tend to establish on dry heaths and drier blanket mires.
Patches of willow scrub dominated by Eared willow Salix aurita are occasional in wetter flush and flushed wet heath habitats and scattered throughout the site. Occasional Downy birch Betula pubescens, Rowan Sorbus aucuparia are found on occasion throughout. Scattered wind-blown Scot’s pine, Lodgepole pine Pinus contorta and Sitka spruce are also found sporadically. Juniper Juniperus communis can be locally abundant, particularly along the gully along the Allt an Tudair where it forms dense stands of mature shrubs. Small stands of Gorse Ulex europaeus are also found in some heath areas. MIRES AND HEATHS Mires and heaths are dominant habitat types across the site. All heath, and on occasion some mire, areas have been subject to regimes of muirburn and in more recent areas of burning precise definition of NVC type is not possible.
Mire communities are frequent throughout the site and occupy areas of deeper peat soils, often found in topographical depressions, gullies and plateaus across the site. On more extensive areas of deeper peats with lower gradients and slower movement of water blanket mire communities are dominant.
Typically, blanket mires on low-mid elevations are dominated by Hare’s‑tail cotton-grass Eriophorum vaginatum, Deergrass Trichophorum germanicum agg., Heather Calluna vulgaris, Cross-leaved heath Erica tetralix and Sphagna. These blanket mires conform to those described in NVC as M17 Trichophorum germanicum-Eriophorum vaginatum blanket mire communities. Most blanket mire communities are subject to ongoing impacts of drainage, with a network of herring-bone drains across the site. Areas of intact mire where impacts of drainage have been slight are rare, and mostly confined to small pockets of deep peat where the high-water table remains. These areas, especially on the flattest ground, have a rich carpet of Sphagna and few eriocoid shrubs and are typical of M17a Drosera rotundifolia-Sph
