Botanical heatmaps and the summarised botanical value map: technical report.
Under the Natural Capital and Ecosystem Assessment (NCEA), Natural England have been working in partnership with the Botanical Society of Britain and Ireland (BSBI) to develop a series of botanical heatmaps derived from plant occurrence records held by the BSBI. This technical report describes how these heatmap layers were developed and outlines the key limitations of these data that must be considered when using these data for land management decision-making. The most important consideration to note is that the survey coverage of the data underpinning these maps is highly variable, where in some areas of poor survey coverage the usability of the maps will be limited. In these areas, other sources of information and/or field survey should be consulted to ensure decisions are supported by the appropriate evidence.
