      High Nature Value (HNV) farmland is extensively managed farmland that has high biodiversity. This farmland is important for the conservation of semi-natural habitats and the plants and animals linked with them. Supporting this type of farmland will ensure high levels of farmland biodiversity, vibrant rural communities, high water, air and soil quality and resistance to flooding among other things. To map the likely distribution of HNV farmland in the Republic of Ireland (ROI) we used five indicators adapted for the Irish context and weighted based on expert knowledge and literature. The indicators used are: semi-natural habitat cover (CORINE land cover), stocking density (Land parcel information system), hedgerow/scrub cover (Teagasc), river and stream density (OSI), and soil diversity (Teagasc). Indicator data sets were included in a weighted sum model that combined raster indicator inputs, representing relative weights and the output HNV farmland had a tetrad-scale (2 km × 2 km) spatial resolution.

      High Nature Value (HNV) farmland is typically characterised by low-intensity farming associated with high biodiversity and species of conservation concern. Mapping the occurrence and distribution of such farmland are useful for appropriate targeting of conservation measures and supporting associated rural communities. We mapped the likely distribution of HNV farmland in the Republic of Ireland using a linear regression model incorporating established European indicators, adapted for Ireland and weightings based on expert opinion. The indicators used were semi-natural habitat cover, stocking density, hedgerow density, river and stream density and soil diversity, with highest weightings placed on the first two indicators (40% and 30%, respectively). The map provides information on the likely occurrence and distribution of HNV farmland in each electoral division as a reference point for future monitoring of the distribution of HNV farmland in the Republic of Ireland in order to assist with planning and policy development for the rural environment.
