迫切需要批发物种丰富度（数量）地图来指导生物多样性的保护。问题是，目前对生物体进行完整的计数是不切实际的。需要既便宜又快捷的间接解决方案。一种方法是重新部署采样工作更高的分类规模，以衡量丰富的属，部落或家庭。高等分类群的数据比物种的数据更有优势，因为它们通常不仅更完整，而且获取成本更低。因此，以同样的成本，调查可以扩大到包括更多的批发生物多样性。种子植物科的数据被用来绘制全世界丰富性的区域分布图和特有性的衡量标准。在植物家族列表中的地区之间的差异，然后排名前十名的互补领域，以最大限度地提高累积家庭丰富度在每一步。
Map of wholesale species richness (numbers) are urgently required to guide the conservation of biodiversity. The problem is that complete counts of organisms are impractical at present. Indirect solutions are needed that will be both cheap and quick. One approach is to re-deploy sampling effort higher up the taxonomic scale, to measure richness among genera, tribes or families. Data for numbers of higher taxa have the advantage over data for species that they are usually not only more complete, but also cheaper to acquire. So for the same cost, surveys could be broadened to encompass more of wholesale biodiversity. Data for seed-plant families were used to map worldwide the regional distribution of richness and a measure of endemism. Differences among areas in plant family lists were then used to rank the top ten complementary areas for maximizing cumulative family richness at each step.
