Efforts at species conservation in the United States have tended to be opportunistic and uncoordinated. Recently, however, ecologists and economists have begun to develop more systematic approaches. Here, the problem of efficiently allocating scarce conservation resources in the selection of sites for biological reserves is addressed. With the use of county-level data on land prices and the incidence of endangered species, it is shown that accounting for heterogeneity in land prices results in a substantial increase in efficiency in terms of either the cost of achieving a fixed coverage of species or the coverage attained from a fixed budget.
美国在物种保护方面的努力往往是机会主义且缺乏协调的。然而，最近生态学家和经济学家已开始开发更系统的方法。在此，探讨了在生物保护区选址中有效分配稀缺保护资源的问题。利用县级土地价格数据和濒危物种分布情况，研究表明，考虑土地价格的异质性会大幅提高效率，无论是从实现固定物种覆盖范围的成本角度，还是从固定预算所能达到的覆盖范围角度来看。
