    The map based index includes outlines for some 8,000 opencast coal prospecting sites dating from the 1940s until the mid 1990s. The index leads to information on the records of some 1 million boreholes (additional to those shown in the Borehole Records layer) drilled during site exploration and also the accompanying plans and other data, all filed in 3,618 boxes. The sites include those that have been drilled and not worked and also those that have been exploited. The original data, hardcopy maps, were received from the Coal Authority in 2001.

    Data identifying landscape areas (shown as polygons) attributed with geological names. The scale of the data is 1:250 000 scale providing a generalised geology. Onshore coverage is provided for all of England, Wales, Scotland and the Isle of Man. Data are supplied as two themes: bedrock and linear features (faults), there is no superficial, mass movement or artificial theme available onshore at this scale. Bedrock geology describes the main mass of solid rocks forming the earth's crust. Bedrock is present everywhere, whether exposed at surface in outcrops or concealed beneath superficial deposits or water bodies. Geological names are based on the lithostratigraphic or lithodemic hierarchy. This means rock bodies are arranged into units based on rock-type and geological time of formation. Where rock-types do not fit into the lithostratigraphic scheme, for example intrusive, deformed rocks subjected to heat and pressure resulting in new or changed rock types; then their classification is based on their rock-type or lithological composition. This assesses visible features such as texture, structure, mineralogy. Data identifying linear features (shown as polylines) represent geological faults at the ground or bedrock surface (beneath superficial deposits). Geological faults occur where a body of bedrock has been fractured and displaced by large scale processes affecting the earth's crust (tectonic forces). The faults theme defines geological faults (shown as polylines) at the ground or bedrock surface (beneath superficial deposits). The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles and are available under BGS data licence.

    Description: Scots pine (Pinus sylvestris L.) has the largest natural distribution of any conifer in the world, ranging from northern Norway to Spain, and from Scotland across Europe and Asia to Siberia and north-east China. It can grow on a range of soil types, surviving where the rainfall is as low as 200mm, and/or where the temperature drops to -64 degrees C. In Scotland, pines were an important component of post-glacial natural forests (the so-called Wood of Caledon) which covered an estimated 70% of the country. They were largely confined to the poorest soils, often occurring in association with birch, but they also grew in mixture with other species in natural transitions to oak, ash and elm dominated woodland on the better soils, and to willows and alder on wet areas. Over many centuries vast areas of these ancient forests were cleared, and pinewood regeneration was prevented, either by allowing the land to be grazed or by replanting it with other tree species, usually of non-native origin. Other adverse effects were the browsing of deer and 'muirburning' to improve the grazing or the age structure of heather on adjacent grouse moors. Pinewoods vary enormously in size, structure and natural species diversity. In Deeside, Strathspey and the Beauly catchment the pine-dominated woodlands are relatively extensive, but in Glen Falloch and Glen Loyne there are only a few old trees scattered over a large area. Other pinewoods occur on steep cliff faces, or in gorge woodlands, such as at Glen Avon, Allt Chaorunn and Attadale, where there may be several age classes present. The wet western pinewoods are more fragmented and isolated than most, and are generally regarded as being in the poorest condition, occasionally merging with oak, alder and other woodland types, indicating that there is scope for re-creating large new mixed native forests in those areas. There are also biochemical differences between pinewoods; these are indicative of genetic variation. Of the seven Regions of biochemical similarity identified, the North West Biochemical Region, near Kinlochewe, is the most distinct, exhibiting considerable differences between individual pinewoods. It is known from the analysis of pollen records taken from peat bogs that pine has been present in North West Scotland for at least 8500 years, but when combined with the genetic information one may begin to speculate that the pines we see now are the direct descendants of trees which survived the last ice age either in Ireland, or possibly on areas of the continental shelf exposed by the lowered sea levels at that time. The pinewoods of the South West Biochemical Region, around Fort William, are another distinct group. They show less variation between the fragments, although it is believed that they had a similar history to those in the North West Biochemical Region. The biochemical characteristics of the other pinewoods in Scotland are not so dissimilar, and these pinewoods seem to have more in common with Central Europe pinewoods. In 1959 Steven and Carlisle published their book 'The Native Pinewoods of Scotland', in which they listed and described most of what they regarded as surviving (ex-Caledonian Forest ) pinewoods. This stimulated an interest in pinewood conservation, and in due course the introduction of a number of incentives to support pinewood management and expansion. More recently the native pinewoods of Scotland have been listed as an endangered habitat in the EC Habitats Directive. They are also the subject of a costed Habitat Action Plan (prepared under the UK Biodiversity Plan) which gives quantitative targets for the protection, restoration and expansion of the pinewoods by both natural regeneration and replanting. These targets are based on an earlier version of this Inventory. ----------------------------------------------------------------------------------------------------------------------------- To prepare the Caledonian Pinewood Inventory, the current extent of the native pinewoods named by Steven and Carlisle, have been investigated. Some of the pinewood fragments which they thought were too small to form discreet pinewood habitats, have also been considered. The total pinewood area now included in the Inventory is nearly 18000 hectares, and comprises 84 separate pinewoods of various sizes. In all cases the balance of probability suggests that they are genuinely native, that is, descended from one generation to another by natural seeding. In addition, each pinewood has: • a minimum density of 4 pine trees per hectare, excluding trees less than 2 metres in height, or at least 50 pine trees per hectare where sites have been extensively underplanted but are deemed capable of restoration to a more natural state; • a minimum of 30 individual trees, unless the wood has historical, aethetic or biological significance; • vegetation which is characteristic of native pinewood, although possibly of a depleted diversity; • a semi-natural soil profile, but accepting also sites with superficial cultivation such as shallow ploughing or scarification with some widely spaced drains. -------------------------------------------------------------------------------------------------------------------------- Inventory Rules: PINEWOOD FRAGMENT Recorded separately if more than 1.5km from another fragment. REGENERATION ZONE Standard 100m but more if conditions indicate spread is likely to be greater (e.g. Glen Tanar). Where regeneration is likely to be less, such as a fragment of pine in an oakwood, then a smaller regeneration zone may be indicated (e.g. Loch Maree Islands). Area does not normally include open water unless the whole of the open water is within the pinewood and regeneration zone. BUFFER ZONE Standard 500m beyond regeneration zone but can be extended further:- 500m beyond watershed or 700m above sea level (e.g. Gleann Fuar) link fragments together (e.g. Barisdale) Buffer zones will not include extensive areas of open water (e.g. South Loch Arkaig) unless the whole of the open water is within the buffer zone. Where the buffer zone includes some ground on the other shore of a loch then the water will be part of the buffer zone (e.g. Loch Hourn). PLANTED AREAS If of correct local origin then accept as pinewood if less than a third of total area of pinewood. The planted areas would be hatched on the maps and recorded as part of the regeneration zone not as part of the pinewood. Planted areas of correct origin, which are alongside pinewood, can have the regeneration zone round them (e.g. Doire Darach). Where a planted area has just been planted or is to be planted and is more than a third of the area of the pinewood, then it may be considered as part of the buffer zone and the buffer zone may be extended to 500m beyond the planted area (e.g. Breda). Planted areas of local origin which are more than 500m from the pinewood will be ignored.

    The Scottish Coastal Forum was formed in 1996 to encourage debate at national level on coastal issues. Its members advise Marine Scotland, from an operational perspective, on the development of policy relating to marine planning and licensing within a sustainable marine environment. The Forum also provides a network for circulating information and best practice in coastal management amongst its own varied membership and the wider Integrated Coastal Zone Management (ICZM) community. Scotland has 7 Local Coastal Partnerships - • Coast Hebrides • East Grampian Partnership • Firth of Clyde Forum • Forth Estuary Forum • Moray Firth Partnership • Solway Firth Partnership • Tay Estuary Forum

    The aim of the Native Woodland Survey of Scotland (NWSS) was to undertake a baseline survey of all native woodlands, nearly native woodlands and PAWS sites in Scotland in order to create a woodland map linked to a dataset showing type, extent and condition of those woods. The objectives were to: 1. Identify the location, type, extent and condition of all native and nearly native woodlands and Plantations on Ancient Woodland Sites (PAWS - as identified from the Ancient Woodland Inventory) in Scotland. 2. Produce a baseline survey map of all native woodland, nearly native woodland and PAWS in Scotland. 3. Collect baseline information to enable future monitoring of the extent and condition of the total Scottish native woodland resource. 4. Provide information to support policy development and the delivery of social, environmental and development forestry. The following datasets are available on the Forestry Commission's Spatial Data Repository (SDR). FC.S_NWSS (base map and polygon level attributes) FC.S_NWSS_INVASIVES_POLYGONS (spatial data for polygons where there is presence of invasive species) FC.S_NWSS_CANOPY_STRUCTURES FC.S_NWSS_HABITAT_COMPONENTS FC.S_NWSS_HERBIVORE_IMPACT FC.S_NWSS_INVASIVES FC.S_NWSS_OTHER_TRAITS FC.S_NWSS_SPECIES_STRUCTURES The following describes the layers available in the FC Scotland Map Browser and also gives an indication of the nature of the spatial data and the related component non-spatial data. (N.B. Every table contains a SCPTDATA_I field. This is a unique field which is used to link all other component tables). If you wish to carry out complex analysis, particularly involving elements of the components tables, e.g. species selection, you should do so using GIS software rather than the FC Scotland Map Browser. NWSS Map: This is a straightforward view of the data which describes the type of NWSS polygon based on the following categories: Native woodland: >50% native species in the canopy Nearly-native woodland: >=40% and <=50% native species in the canopy Open land habitat: <20% canopy cover, usually 100% surrounded by woodland and adjoining a native woodland PAWS: A woodland area wholly or partially identified in the Ancient Semi-natural Woodland Inventory as ancient semi-natural but currently not semi-natural. NWSS Nativeness: Displays the percentage share of native species in the total canopy. This ranges from 0% to 100% in 5% classes. NWSS Habitat: This view of the data shows the priority woodland type and National Vegetation Classification (NVC) woodland community. Open land habitat is defined by UK Biodiversity Action Plan (BAP) type. A dominant habitat is recorded for each polygon, however some polygons have habitats of equal dominance. In this case only one of the habitats is recorded in the top level spatial data. To identify all of the habitats in a particular polygon please refer to the FC_S_NWSS_HABITAT_COMPONENTS table or use the map browser identify tool on the NWSS Habitats layer. Plantations on Ancient Woodland Sites (PAWS) may not display in the Habitat layer if a surveyor has not recorded a native priority habitat type for the site. This will happen when a site is non-native. NWSS Canopy Cover: Displays as a percentage, an assessment of the area covered by trees/shrubs. Values range from 0% to 100% in 10% classes. A minimum of 20% canopy cover is required to define woodland, so the 10% and 20% bands are skewed to allow for this. NWSS Canopy Structures: This displays the number of different structures recorded in a polygon (ranging from 0 to 6). The types of recorded structures are veteran, mature, pole immature, shrub, established regeneration or visible regeneration. A dominant structure is recorded for each polygon, however some polygons have structures of equal dominance. In this case only one of the structures is recorded in the top level spatial data. To identify all of the structures in a particular polygon please refer to the FC_S_NWSS_CANOPY_STRUCTURES table or use the map browser identify tool on the NWSS Canopy Structures layer. Information on the species identified in each polygon is also in the NWSS Canopy Structures layer and table. * indicates a species which is classed as native for the purpose of the survey. + indicates a species is a shrub not a tree. NWSS Semi-naturalness: This view of the data shows the percentage of the polygon that is semi-natural. Values range from 0% to 100% in 10% bands. NWSS Maturity: This indicates the approximate stage of woodland development as either: mature, young, regenerating, mixed or shrub. The value is based on the dominance of the structures recorded; a mixed maturity means that none of the others values are dominant. NWSS Other Traits: This layer records whether or not there are any other attributes which have been recorded in the polygon. The details of any other traits that have been found can be accessed by viewing the related information attached to a polygon. NWSS Herbivore Impact: This view of the data shows the overall impact that herbivores have had on a polygon. NWSS Invasives: This is a separate spatial dataset on the Forestry Commission Spatial Data Repository. It contains a subset of the overall NWSS Map dataset which includes only those polygons were there is some presence of an invasive species. The layer is symbolised on the percentage of invasive species with the polygons, show in 25% bands. The data itself contains more detailed information which is broken down into 5% bands.

    In response to a 1980 select committee which recommended that ancient woods should be recognised and treated as a separate category, the NCCs compiled the Inventories of Ancient, Long-established and Semi-natural woodlands. A more sophisticated classification was developed for woodlands in Scotland due to the nature of the available historical sources. IMPORTANT. For Scottish woods, the category Ancient comprises woods recorded as being of semi-natural origin on EITHER the 1750 Roy maps OR the 1st Edition Ordnance Survey maps of 1860. This is due a) to the likelihood of the latter having been omitted from the Roy maps and b) to render the Scottish classification compatible with that for England and Wales.
