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).Explanation of attributes can be found in the HIA_attributes spreadsheet.
