    The purpose of this data is to indicate the relative wildness across Scotland. The dataset is on a scale of 1-256 indicating relative levels of wildness. Consequently the data is best viewed at a national or regional scale. The methodology is adapted from the 2008 Wildness Study in the Cairngorms National Park. Four principal attributes identified in SNH's policy statement(Wildness in Scotlands Countryside, 2002), namely perceived naturalness of land cover, ruggedness, remoteness and the lack of built modern artefacts are mapped using GIS based techniques and a combination of readily available datasets. An index of wild land quality is then derived by combining the individual attribute layers. The attribute layers are given equal weighting.

    The Standing Waters Sample Points dataset is a GIS dataset of survey sample locations used during the course of the Scottish Loch Survey Project. The statutory nature conservation agencies in Scotland, England and Wales have a long history of carrying out routine aquatic plant (macrophyte) surveys of lakes. This involves identifying and estimating the abundance of emergent, submerged, floating leaved, and free-floating macrophytes that grow in or near the water. The results of these surveys are held in the Standing Waters Database which is available to view on the SNH website. (http://gateway.snh.gov.uk/pls/apex_cagdb2/f?p=111:1000:1289803086875801).

    Many countries around the world have begun to adopt zonation systems as a strategic framework to guide their approach to the conservation, enhancement, understanding and use of the natural heritage. The natural heritage zonation approach adopted by SNH is intended to provide a logical framework, reflecting the diversity of Scotland's natural heritage, within which SNH can clearly and simply plan and execute its work. The zones are not, therefore, intended as a classification of the natural heritage but, rather as an operational tool which is founded in the natural heritage.

    One of four component layer of the Scottishmap of relativewildness. This layer shows the level of modern artefacts (detractors)that are visible. The dataset is on a scale of 1-256 indicating relative levels of visual influence. Consequently the data is best viewed at a national or regional scale. The methodology is adapted from the 2008 Wildness Study in the Cairngorms National Park. NextMap Digital Surface Model (DSM) gives the height of the surface including the detractors from which a viewshed can be produced. Viewsheds up to 15 km were created for 3 feature layersat 50m resolution, 1) Buildings and other structures, 2) Railway lines, roads and tracks and 3) Pylons and ski lifts. A fourth viewshed up to 30 km was created for wind turbineswhose heights were added to a DTM. The resulting calculations were then re-scaled 1-256 to produce the map of lack of built human artefacts.

    Local nature reserves are areas of (at least) locally important natural heritage, designated and managed by local authorities to give people better opportunities to learn about and enjoy nature close to where they live. They are found across the country, but generally close to towns and cities. More details are available here: http://www.snh.gov.uk/protecting-scotlands-nature/protected-areas/local-designations/lnr/ Where we have not been supplied with data by local authorities we are extracting it from a previously produced SNH national dataset.

    Tree Preservation Orders in Angus

  • Categories  

    Nature Conservation Orders (NCOs) are made to protect any natural feature of land that is within (1) a site of special scientific interest (SSSI), (2) a European site or (3) other land of special interest, and where it is either being actively damaged or there is evidence that it is under threat of damage. The Orders set out certain prohibited operations and the land to which they apply.

    The Core Paths aim to satisfy the basic needs of local people and visitors for general access and recreation. They comprise a mixture of existing and some new paths. The Core Paths cater for all types of users - walkers, cyclists, horse riders, people with disabilities, and are a key part of outdoor access provision. The Fife Core Path Network is shown as lines, covering the whole of Fife, on the approved Core Path Plan as defined by a public consultation and public inquiry, as mandated by the Land Reform (Scotland) Act 2003 that placesm,on the local authority, the duty to draw up a plan for a system of paths ('core paths') sufficient for the purpose of giving the public reasonable access throughout their area'. These 'core paths' systems will be available for recreation and everyday journeys by local people and visitors, providing opportunities for walking, cycling, riding and other activities for all ages and abilities.
