    A geomorphological assemblage map of the Cairngorm Mountains, from Glen Feshie in the west to Loch Builg in the east. The Cairngorm Mountains represent one of the finest assemblages of glacial and mountain landforms in the world, particularly noted for the diversity of features in a relatively compact area. These features incorporate a wealth of information about past environmental change and landscape evolution through periods of tropical, ice age and modern temperate climates. This landform heritage represents a precious educational and environmental resource, one which is unusual in the wide range and quality of the features that have taken millions of years to evolve. The area has been recognised as "unquestionably of international importance, particularly for the close juxtaposition of relic landscape and of glacial erosion and deposition" (Cairngorms Working Party, 1993, p.13 paragraph 2.1.1.3). http://www.snh.gov.uk/publications-data-and-research/publications/search-the-catalogue/publication-detail/?id=1546

  • This dataset combines all available field data for upland habitat impact assessment (HIA) survey work commissioned by SNH between 2004 and 2018 using the methods described in (Macdonald et al 1998). Data collation was carried out by Edward Wilson as part of the review of deer data Project 017079 managed by Jenny Bryce of the Wildlife Management Activity Team. The aim was to bring together all the available into a corporate dataset, standardise and clean the data and make it accessible for internal and external use. It should be used as the primary source of HIA data as it supersedes (through data cleansing) the data held in spreadsheets. Data refer to small-scale field indicators for grazing and trampling impacts by ungulates - most notably deer and sheep. NB not all indicators are appropriate to a given location, and where this is the case, data are referred to as not applicable (NA), adjacent to the relevant indicator. Additional field data include quantitative and trend measures. Attribute data, including Deer Management Unit, Deer Management Group, designated sites, and - where field-based observations are missing - NVC data, have been obtained from available SNH GIS data. Feature(s) of interest data has been determined based on survey Statements of Requirements and site-level designations (NB where both Natura and SSSI designations overlap, the former is prioritised unless otherwise stated in survey objectives), NVC descriptions and SNH specialised knowledge. Some apparent localised location discrepancies (e.g., points lying outside designated boundaries) do occur occasionally with this data, owing to GPS and human error from the time of survey. The method for producing summary grazing and trampling impact classes for each point have been standardised using a median value (or an intermediate class where there are equal numbers) and hence the summary descriptions (L, ML, M, MH, H) presented in this dataset may vary from those in the original surveyors spreadsheets. Indicator attribute names are coded to state the field guide habitat, as prefix (e.g. SG, for smooth grassland indicators); followed by the type of indicator or measure assessed (i.e., ’Q’, ’I’, ’T’ for quantitative, indicator and trend measures, respectively); the number of the measure, in order; and whether the measure is associated with grazing (‘GR’), trampling (‘TR’) or dunging (‘DU’) by ungulates. The order of the specific measures are taken from MacDonald et al. (1998) small-scale indicators for grazing and tramping impacts (only); the ordering of quantitative measures, which came into being after the guide publication, are determined from SNH document ‘DRAFT HIA Indicator tables 2017 v0.1.docx’ (A2479946). Survey data split into 8 separate layers based on the contents of the field forms used for collection: Blanket bog Dwarf shrub and heath Flushes U7 - U13 Snowbeds Scrub Smooth grassland Tall herbs Wind-clipped heath Explanation of attributes can be found in the HIA_attributes spreadsheet. Additional surveys will be added at irrgeular intervals.

    The windfarm footprint map is intended to provide an overview only and we endeavour to keep the map as up to date as possible. However, users should note: •The map is updated regularly, but will never be 100% accurate. •There are several 'gaps' on the map where SNH are seeking appropriate mapping of proposals to add to the map. •The map should not be used to form the basis of detailed environmental assessment or regional planning work - it is an overview only. •The map shows the approximate physical footprint of the wind farm and is usually based on the site boundary as shown on the Environmental Statement. Where we don't have site boundary, a turbine 'envelope' is used instead, using the outer turbine locations. This will often include site access tracks, but generally excludes grid connections. •The map does not show the 'visibility' footprint of the windfarms, it shows the physical footprint only. •It is acknowledged that the word 'footprint' could be misleading - it does not represent the physical footprint of the turbines (or their foundations) themselves - it shows the area of land occupied by the windfarm and is intended to illustrate the relative scale of windfarm proposals. •The map only shows windfarms which are installed, consented, in planning or at scoping stage. It does not show proposals which are still confidential, or proposals which have been withdrawn or refused consent. •The map does not include small domestic wind turbines and generally only includes wind turbines of greater than 50m in height. •The map only includes proposals on which SNH are consulted, some small wind clusters or community scale proposals, which have not been reviewed by SNH may not appear. Note: this is not necessarily a comprehensive dataset of all wind farm schemes in the public domain and there may be some errors in the information supplied on this map. Windfarms which have been withdrawn from planning or refused consent do not appear on the map.
