A survey of breeding Hen Harrier reported that 128 to 172 breeding pairs were recorded in 2010 which was broadly similar to the totals recorded in the previous survey in 2005. However notable declines were recorded in some traditional strongholds of this species’ breeding range (Ruddock et al., 2012). In 2014 a Hen Harrier Habitat Mapping Project focusing on these SPAs and based on remote sensing techniques was undertaken. This project was to produce a contemporary geospatially digitised habitat map for the six SPAs. This project produced a contemporary geospatially digitised habitat map for the six SPAs. This projects was to use habitat categories that broadly correspond to the Fossitt Classification system (Smith et al., 2011), distinguish habitats of ecological relevance to Hen Harrier, to use a mapping resolution corresponding to the Ordnance Survey Ireland 1:5000 base-map to allow land use within discreet enclosed land parcels to be readily identifiable.

A spot height may be expressed as AOD for "above ordnance datum". Usually mean sea level (MSL) is used for the datum. Malin Ordnance Datum Derivation of vertical height or depth (in metres) In the Republic of Ireland, OD for the Ordnance Survey of Ireland is Malin Ordnance Datum: the Mean Sea Level (MSL) at Portmoor Pier, Malin Head, County Donegal, between 1960 and 1969. 5731 EPSG Projection 5731 - Malin Head height Metres Derivation of Altitude OD based on Mean Sea Level, Malin Head 1960-1969 OGC Web Map Service V1.3 National Parks and Wildlife Service Department of Housing, Local Government and Heritage Ecological Data Manager +353-1-8882000 - National Parks and Wildlife Service 90 North King Street Dublin 7 D07 N7CV Ireland datadelivery@housing.gov.ie.ie https://dahg.maps.arcgis.com/apps/webappviewer/index.html?id=a964809ffbad4c16ae2c4ec72f5d3921 application/html Hen Harrier Habitat Map Viewer Visualisation of Hen Harrier Habitat map dataset https://services-eu1.arcgis.com/Jhij7i46ouO8Cc0N/arcgis/rest/services/HenHarrierSPAHabitatMapping/FeatureServer ESRI REST ESRI REST ESRI REST https://dservices-eu1.arcgis.com/Jhij7i46ouO8Cc0N/arcgis/services/HenHarrierSPAHabitatMappingWFS/WFSServer?service=wfs&request=getcapabilities WFS WFS WFS INSPIRE Data Specification on Habitats and Biotopes INSPIRE Data Specifications v3.0 2013-12-10 The INSPIRE Directive or INSPIRE lays down a general framework for a Spatial Data Infrastructure (SDI) for the purposes of European Community environmental policies and policies or activities which may have an impact on the environment. false COMMISSION REGULATION (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services INSPIRE Interoperability Regulation 2010-12-08 Level of conformance with the COMMISSION REGULATION (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services false The OSI 1:5000 boundary line was chosen as the base-layer upon which all habitat mapping was based. The SPA boundary data to be used for all habitat mapping was version 3 (Positioning Accuracy Improved (PAI) SPA boundaries in ITM). Previous versions of the SPA boundary were mapped on six inch maps and there are a number of discrepancies in SPA boundaries fitting neatly onto field boundaries in OSI 1:5000. If there were fields traversing the SPA boundary whole field, as it exists in the OSI 1:5000 base layer, was mapped. For this reason, a 500m buffer round the SPA boundary was established prior to mapping to ensure that any overlap was afforded full coverage in the habitat map. All habitats mapped by discrete polygons/lines were assigned an attribute “LAND_PARCE” within the relevant shape-file. “Select by location”, was utilised to select if the discrete polygon/line feature was within the SPA boundary. Features contained within the SPA boundary have a value of “IN” for this attribute. Features traversing the SPA boundary, or outside of the boundary but considered of importance with regards to providing an ecological corridor (such as a hedgerow bounding a field that has been excluded from the SPA) have a value of “OUT” for this attribute.
