European Ocean Biodiversity Information System

BVMtool is a set of R scripts automating marine biological valuation calculations based on the biological valuation concept as developed by Derous et al. 2007 and described by Deneudt et al 2013. Based on a recommended format for data input, the script facilitates the calculation of a number of valuation questions that are commonly solved when observational data on species densities are available. The results of the valuation questions are summarized in final scores for each ecosystem component and can be combined with the final results obtained for other ecosystem components. Subzones can be defined as raster grid cells of a desired size or can be based on polygons of a habitat classification provided by the user. The script also offers the possibility to run a number of quality control procedures on the input data, including a taxonomic quality control using the web services built on the World Register of Marine Species.
