Svalbard rock ptarmigan spring breeding habitat suitability raster map from Pedersen et al. (2017). The habitat suitability map was developed using 11 years (2000–2010) of presence/absence data of territorial males from monitoring, a multi-scale generalized linear modelling framework (glms), and digital satellite-based vegetation mapping. The final habitat model contained four significant predictors related to vegetation, terrain (elevation and slope) and heat load index. High values indicate better breeding habitat suitability. Spatial resolution of the map is 100 x 100 m. Provided in UTM 33N / WGS84 (CRS: 32633). See Pedersen et al. (2017) for more information.
