The Natural Land Pattern Index (NLPI) assesses the spatial pattern of the natural/semi-natural land by reporting the area (in km2) covered by six spatial pattern classes (core, edge, perforation, islet, margin, core-opening) in which natural/semi-natural land has been classified as of 2015. The Natural Land Pattern Dynamics (NLPD) reports the trends in the area occupied by these pattern classes in the last 20 years (1995-2015). The six pattern classes are determined based on the spatial context and size of the patches of natural/semi-natural land cover, accounting for its proximity to non-natural (agricultural and urban) areas. See below (Use and Interpretation section) for a detailed description of these six classes.
