Datasets used to evaluate how well rarity-weighted richness selects sites that efficiently represent species.

Datasets are listed in order of size of sites.1In each inventory dataset, an attempt was made to inventory all species at each site. In each atlas dataset, each site was a grid cell, and the data consisted of all species records in the cell.2 US National Park Service Inventory Products http://science.nature.nps.gov/im/inventory/veg/products.cfm (accessed 20 June 2014)3 Ministry of Agriculture Food and Environment of Spain.
